ISS-Imagery in the period 2015-1998

• December, 2015: Expedition 46 Flight Engineer Tim Kopra on a Dec. 21, 2015 spacewalk, in which Kopra and Expedition 46 Commander Scott Kelly successfully moved the International Space Station's mobile transporter rail car ahead of the Dec. 23 docking of a Russian cargo supply spacecraft. After quickly completing their primary objective for the spacewalk, Kelly and Kopra tackled several additional "get-ahead" tasks. Kelly routed a second pair of cables in preparation for International Docking Adapter installment work to support U.S. commercial crew vehicles. Kopra routed an Ethernet cable that ultimately will connect to a Russian laboratory module. They also retrieved tools that had been in a toolbox on the outside of the station, so they can be used for future work. -The three-hour and 16-minute spacewalk was the second for Kopra, who arrived to the station on Dec. 15, and the third for Kelly, who is nine months into a yearlong mission. 1)

• On Dec. 11. 2015, Expedition 45 crew members Kjell Lindgren of NASA, Oleg Kononenko of Roscosmos and Kimiya Yui of JAXA safely concluded their nearly 5 month mission aboard the massive orbiting lab complex with a soft landing on the frozen steppes of Kazakhstan. The trio, led by Soyuz commander Kononenko, leave behind three more comrades from Russia and America who remain aboard the ISS until early March, including the first ever one year mission crew comprising Station Commander Scott Kelly of NASA and Mikhail Kornienko of Roscosmos. 2)

- The station crew will soon be supplemented by the remaining half of Expedition 46, comprising the three new crew members of NASA astronaut Tim Kopra, Russian cosmonaut Yuri Malenchenko and Tim Peake of ESA (European Space Agency). They are slated to blastoff from the Baikonur Cosmodrome, Kazakhstan, on Dec. 15, 2015.

• November 16, 2015: Using a powerful lens, an astronaut aboard the ISS photographed the north end of the Suez Canal, along with the city centers and port facilities of Port Said and Port Fuad. Local ship traffic takes on and discharges cargo at the angular shaped docks. A long breakwater protects ships in canal from the prevailing westerly winds and waves that blow across the canal entrance. Muddy, light-brown water from the Nile delta banks up against the west side of the breakwater. 4)

- Both ports lie on the west fork of the canal. The east fork was specifically built to allow ships on long hauls—typically between Europe and Asia, via the Mediterranean Sea—to avoid congestion at the west-fork ports. In 2014, Egypt announced plans to ease congestion by digging another canal parallel to the present one; canal tolls provide much needed foreign exchange for Egypt. Current plans only include a parallel canal along half pf the 160 km length.

As of November 2, 2015, the ISS achieved 15 years of a continuous human presence in orbit — aboard the football field sized research laboratory ever since the first Russian/American crew of three cosmonauts and astronauts comprising Expedition 1 arrived in a Soyuz capsule at the then much tinier infant orbiting complex on Nov. 2, 2000. 5)

Figure 6: The 6 person ISS Expedition 45 Crew celebrates 15 Years of operation with humans on 2 Nov 2015. The complete Expedition 45 crew members include Station Commander Scott Kelly and Flight Engineer Kjell Lindgren of NASA, Flight Engineers Mikhail Kornienko, Oleg Kononenko and Sergey Volkov of the Russian Federal Space Agency (Roscosmos) and Flight Engineer Kimiya Yui of the Japan Aerospace Exploration Agency (image credit:: NASA)

- The space station is the largest engineering and construction project in space combining the funding, hardware, knowhow, talents and crews from 5 space agencies and 15 countries – NASA (USA), Roscomos (Russia), ESA (European Space Agency), JAXA (Japan Aerospace and Exploration Agency) and CSA (Canadian Space Agency).

- The collaborative work in space has transcended our differences here on Earth and points the way forward to an optimistic future that benefits all humanity.

- The station orbits at an altitude of about 400 km above Earth. It measures 109 m end-to-end and has an internal pressurized volume of 915 m3, equivalent to that of a Boeing 747.

- Over the past 15 years, after more than 115 construction and logistic flights, the station has grown by leaps and bounds from its small initial configuration of only three pressurized modules from Russia and America into a sprawling 450,000 kg orbiting outpost sporting a habitable volume the size of a six bedroom house, with additional new modules and hardware from Europe, Japan and Canada. — The ISS has been visited by over 220 people from 17 countries.

- The longevity of the ISS was recently extended from 2020 to 2024 after approval from President Barack Obama. Most of the partners nations have also agreed to the extension. Many in the space community believe the station hardware is quite resilient and hope for further extensions to 2028 and beyond (Ref. 5)


• October 28, 2015: Having reached the halfway mark of his latest one-year mission and overall logging a record-breaking time in space approaching 400 days, U.S. astronaut and commander of the current Expedition 45 crew Scott Kelly has been dazzling audiences with beautiful pictures taken from beyond Earth's atmosphere. He recently photographed the Nile River during a nighttime flyover on Sept. 22, 2015 (Figure 7). 6)

- The The Nile is the longest river in the world at 6,650 km. Although typically associated with Egypt, the river also flows through Burundi, Ethiopia, Sudan and Uganda, providing water to more than 300 million people.


Figure 7: NASA astronaut Scott Kelly captured this nighttime image on Sept. 22, 2015 of the Persian Gulf and Nile River, which empties into the Mediterranean amid the bright lights of Cairo the Nile Delta and many cities and urban areas (population centers) in the Near East (image credit: NASA/JSC)


• Sept. 7, 2015: Figure 8 is an astronaut photo from the ISS of Chilubi Island in Zambia. The light-toned sand island stands out from the dark waters of Lake Bangweulu. In the two photos, we see a few patches of open water between the fingers of the island. The waters are crowded by areas of aquatic vegetation and wetland (reeds, papyrus, and floating grass) in green. Lake Bangweulu, which is only 4 m deep on average, is rich enough to supply fish for the copper-mining towns to the west. 7)

- Chilubi Island has 100 km of coastline, providing prime access to the richest fishing waters in northern Zambia. Those coastlines are smoothed by easterly winds that erode ancient sand dunes. The narrow strips of lighter toned land along the shorelines are areas that have been mostly denuded of vegetation by residents of the densely populated fishing villages. - The UK explorer and missionary David Livingstone (1813-1873) was the first European to visit the lake in 1868.

Figure 9: This is an image of the OLI camera on Landsat-8, acquired on August 22, 2015, providing a perspective view of Chilubi Island and Lake Bangweulu (image credit: NASA Earth Observatory, M. Justin Wilkinson)


• August 24, 2015: The astronaut photos of Figures 10 and 11 were acquired on August 10, 2015 by a member of the Expedition 44 crew, with a Nikon D4 digital camera using a 28 mm lens, and are provided by the ISS Crew Earth Observations Facility and the Earth Science and Remote Sensing Unit, Johnson Space Center. 8)

- These photos show the sprite's tendrils reaching as much as 100 km above Earth's surface. Sprites are major electrical discharges, but they are not lightning in the usual sense. Instead, they are a cold plasma phenomenon without the extremely hot temperatures of lightning that we see underneath thunderstorms. Red sprites are more like the discharge of a fluorescent tube. Bursts of sprite energy are thought to occur during most large thunderstorm events. They were first photographed in 1989.


Figure 10: Viewing from a point over northwest Mexico, astronauts aboard the ISS looked northeast and shot this unusual photograph of a red sprite above the white light of an active thunderstorm. In this figure, acquired on August 10, 2015, the sprite was 2,200 km away, high over Missouri or Illinois; the lights of Dallas, Texas appear in the foreground. The sprite shoots up to the greenish airglow layer, near a rising moon (image credit: NASA/JSC)


Figure 11: Two minutes and 58 seconds later, as the ISS was over the coastal Mexican resort of Acapulco, the crew documented another red sprite over a brilliant white thundercloud and lightning discharge near the coast of El Salvador. The shorter distance to the storm—about 1,150 km—makes it somewhat easier to see details of the sprite. City lights are a diffuse yellow because they are shining through clouds (image credit: NASA/JSC)


• August 10, 2015: Astronauts on the International Space Station recognize the smooth, broad bend that separates mountains and plains as the Front Range of the Rocky Mountains. This sudden break between plains and mountains makes Denver one of the most spectacular cities in the United States. Canyons cut through the snow-covered mountains. Boulder Canyon provides water to the city of Boulder, while tourists exploring the Rocky Mountains pass through Idaho Springs in the Clear Creek valley. 9)

- The plains fronting the mountains are now heavily populated. The cities and urban counties centered on Denver have an estimated population of 2.7 million people. The rectangular plot of highways and main roads gives the cityscape a blocky appearance—a pattern that has spread southward more than 40 km to the wooded hills south of the town of Parker.

- Rich farmland competes with urban land uses areas in the fertile Platte River valley (bottom right of the image) and surrounding plains north of Denver. This intensively farmed area appears from space as a pattern of numerous smaller plots. Less intensive land-use areas (such as spring and winter wheat) are marked by much larger plots of land, as seen around Denver's international airport.


Figure 12: This astronaut photo of the Expedition 44 crew, ISS043-E-156572 of the Denver region, was acquired on April 29, 2015 with a Nikon D4 digital camera using a 140 mm lens (image credit: NASA/JSC Gateway to Astronaut Photography of Earth)


• June 29, 2015: The astronaut photo (Figure 13) from the ISS, provided by the Expedition 43 crew, depicts the brightly colored Laguna Colorada in the Bolivian Andes Mountains. The lack of atmospheric haze at high altitude — the lake sits 4,300 m above sea level — helps make images of the region especially clear. The strong red-brown color of this shallow, 10 km long lake is derived from algae that thrive in its salty water. 10)

- Occasionally the lake has green phases as well because different algae display different colors. The type of algae at any given time is determined by the changing salinity and temperature of the water. As lake water evaporates in the desert climate, it becomes saline. Ancient shorelines show that the lake has been larger in the past.

- Laguna Colorada is the center of a wildlife reserve, and it was listed in 1990 as a "Ramsar Wetland of International Importance." The lake is home to vast numbers of flamingos.

- Snow-capped volcanoes appear at the top center and lower left. Access roads on three sides of the lake are used by tourists to visit these other-worldly landscapes.

• June 13, 2015: On his last full day in space aboard the ISS, NASA astronaut Terry Virts captured a truly iconic shot of one of the "Seven Wonders of the World" – the Great Pyramids of Giza in Egypt. The three pyramids of Giza dominate the fantastically beautiful photo. They are located about 9 km from the town of Giza on the Nile, and some 25 km southwest of the Egyptian capital city of Cairo. 11)

• June 11, 2015: Three crew members of the ISS (International Space Station) returned to Earth on the Soyuz TMA-15M spacecraft after a 199-day mission that included several spacewalks, technology demonstrations, and hundreds of scientific experiments spanning multiple disciplines, including human and plant biology. 12)

- During their time aboard the orbiting laboratory, the crew members participated in a variety of research activities focusing on the effects of microgravity on cells, Earth observation, physical science, and biological and molecular science. Their research included the start of a one-year study into human health management over long-duration space travel with the March arrival of NASA astronaut Scott Kelly and Roscosmos cosmonaut Mikhail Kornienko — the One-Year Crew.

- In preparation for the arrival of U.S. commercial crew vehicles, Virts ventured outside the station for three planned spacewalks to make adjustments for new International Docking Adapters (IDA) that can accommodate the spacecraft. The first IDA is scheduled to arrive on SpaceX's seventh commercial resupply flight later this month.

- The returning crew members will celebrate individual milestones in their space exploration careers. With the completion of his second mission, Virts now has spent 212 days in space. Shkaplerov, having completed his second long-duration mission on the station, has spent 364 days in space. Cristoforetti set a new record for single mission duration by a female astronaut with 199 days in space on her first flight, surpassing NASA astronaut Suni Williams' previous record of 195 days as a flight engineer on Expeditions 14 and 15 from December 2006 to June 2007.


Figure 15: Expedition 43 Commander Terry Virts of NASA, Flight Engineers Anton Shkaplerov of the Russian Federal Space Agency (Roscosmos) and Samantha Cristoforetti of ESA touched down on June 11, 2015, southeast of the remote town of Dzhezkazgan in Kazakhstan (image credit: NASA TV)


• Since docking with the International Space Station on 24 November 2014, the Soyuz TMA-15M has been waiting for its return flight to Earth. On June 11, 2015, ESA astronaut Samantha Cristoforetti, NASA astronaut Terry Virts and cosmonaut commander Anton Shkaplerov will enter the spacecraft and close the hatch after 200 days in space. 13)

- Not much will remain of the craft once it lands on the Kazakh steppe some three hours after leaving the Space Station. The vessel will separate into three modules, with only the middle one designed to survive the extreme heat and forces of reentry. The sections sporting the solar wings, symbols and antenna will burn up harmlessly in the atmosphere.

- When the trio slowly back away from the Station at around 10:20 GMT they will be travelling at 28 800 km/h relative to the ground. The Soyuz thrusters, parachutes and even springs will bring them to a halt with a thump at the end of their mission.

- It is a bumpy ride, but a safe one. Each Soyuz comes with a ‘space warranty' of 210 days, leaving TMA-15M with a comfortable margin as it comes home.

• June 8, 2015: Astronauts aboard the ISS used a high magnification lens to capture the details of the Aswan High Dam on the River Nile in southern Egypt. This vast engineering project was started in 1960 and completed in 1970, and it is one of the largest earthen embankment dams in the world at 3,830 m long and nearly 1,000 m wide. 15)

- The Aswan High Dam holds back 132 km3 of water in Lake Nasser. Hydropower generated at the dam wall provides 2.1 GW— which was fully half of Egypt's needs in 1970 — giving numerous villages access to electricity for the first time. The dam virtually eliminated the danger of floods downstream in the Nile Valley, which has had both positive and negative effects downstream.

- The highly indented shoreline of 550 km long Lake Nasser is a familiar sight to astronauts. Building the new reservoir necessitated the relocation not only of nearly 100,000 residents, but also of four famous archaeological sites that were later reconstructed in sites above the lake level. The tourist road that passes near the airstrip (Figure 18) leads to the massive rock temple of Abu Simbel (outside the image), built by Pharaoh Ramses II in the 13th century BCE. The temple was reassembled above the shoreline of Lake Nasser.


Figure 18: The astronaut photo of the Aswan High Dam was acquired on April 12, 2015, with a Nikon D4 digital camera using an 800 mm lens, taken by a member of the Expedition 43 crew (image credit: NASA/JSC)


• June 1, 2015: The photo of Figure 19 was taken as astronauts on the International Space Station flew over the delta and green swamps of the Paraná River on the Atlantic coast of Argentina. The Paraná, South America's second largest river after the Amazon, pours muddy water into a wide estuary known as the Plata River. 16)

- The gray mass of Argentina's capital city, Buenos Aires (metro population of 12.7 million in 2010), is less prominent when viewed from space, although astronauts quickly attune their eyes to the subtle signature of cityscapes. Numerous small farm plots on red soils surround the delta and city. — The muddy, brown Paraná originates in the Andes Mountains. The river mirrors the Amazon, which is also turbid and arises in the Andes. In this image, tidal backwash transports muddy water a short distance upstream into the smaller Uruguay River.

• May 11, 2005: ESA astronaut Samantha Cristoforetti is sharing her world in space with video tours of her experiments, the space toilet and bathroom as well as giving lessons about gravity. Samantha's mission is named ‘Futura' to highlight the science and technology research she runs in weightlessness to help shape our future. She is flying as an ESA astronaut for Italy's space agency ASI under a special agreement between ASI and NASA. Samantha, Terry Virts and Anton Shkaplerov arrived at the Space Station when their Soyuz TMA-15M spacecraft docked with the space laboratory on 24 November 2014. Since then they have seen five supply spacecraft arrive and leave, and worked on countless experiments. As much time as possible is spent on science during their 40-hour working week. Samantha runs experiments from ASI and ESA, but takes part in even more from scientists all over the world. Many are continuations from previous expeditions – the longevity of the International Space Station is part of what makes it so special for scientists. 20)

• April 27, 2015: The photographs of Figure 22 and Figure 23 were acquired on April 10, 2015 as astronauts aboard the ISS flew over the headlands of the southern Brazilian port city of Florianópolis. The east side (top right) and west side (lower left) of the city are joined by bridges spanning the 400 m wide narrows. The International Airport of Florianópolis appears on the lower right in both images. The city has one of the highest-quality-of-life indices in Brazil. 21)

- Astronauts gain a sense for the sunglint point moving across Earth's surface as the ISS is orbiting the planet. These images are an example of the training, crews receive in the special effects inherent in near-glint-point images of water bodies. The astronaut photographs ISS043-E-101431 and ISS043-E-101445 were acquired with a Nikon D4 digital camera using an 800 mm lens, and are provided by the ISS Crew Earth Observations Facility and the Earth Science and Remote Sensing Unit, Johnson Space Center. The images were taken by a member of the Expedition 43 crew. The images have been cropped and enhanced to improve contrast, and lens artifacts have been removed.


Figure 22: This image is illuminated by the partial reflection of the Sun. This sunglint reveals many details in the water surface, especially wind streaks and boat wakes. The water south of the city is far brighter than to the north, probably because the hills of the city protect water surfaces from the wind on the leeward side, leading to calmer water and a brighter reflection. On the day of the photograph (April 10, 2015), the winds were blowing from the north (upper left), meaning waters were calmer south of the city.


Figure 23: This photo was taken just 31 seconds after the glint point had moved off the view, and it shows quite different features in the water—especially the brown, muddy outflow of a small stream that enters the bay near the airport. Most coastlines show faint brown tinges in the water; these arise from wave action stirring up shoreline muds, as well as from city pollution.


• April 1, 2015: NASA astronaut Terry Virts shared his views of Super Typhoon Maysak, including this terrifying view looking straight down into the huge eye of the storm (Figure 24). The Pacific Ocean typhoon has slammed several Micronesian islands, killing 5 people so far, and is now on its way westwards to the Philippines. As of early on April 1, Maysak had sustained winds of 240 km/h, equivalent of a category 4 hurricane. Gusts as high as 390 km/h are possible with this storm. 22)

• March 30, 2015: The east-looking astronaut photo of Figure 25 from the ISS shows the arid landscapes of the Sahara and the darker vegetation of the wetter, semi-arid woodland known as the Sahel. 23)

The dark green marshes of Lake Chad stand out in the foreground. Even though it is more than 200 km long, modern Lake Chad is just a small remnant of a vast lake that has repeatedly occupied the most of this landscape in the recent geological past. This lake basin stretches almost 1000 km from the foreground of the image to the foot of the Tibesti Mountains. The lowest slopes of the Tibesti show the remnants of great deltas.

The image also captures an active dust plume, though it is partly obscured by the "Canadarm" of the Space Station. The dust rises from the white mud flats of the ancient lake bed, likely from the Bodele Depression. Lofted into the atmosphere by northeasterly winds, dust from this basin often reaches the Atlantic Ocean, which is thousands of kilometers to the west. Occasionally this dust is even carried by weather systems as far as the Americas.

Legend to Figure 25: This photograph was acquired with a Nikon D4 digital camera using a 32 millimeter lens, and is provided by the ISS Crew Earth Observations Facility and the Earth Science and Remote Sensing Unit, Johnson Space Center. The image was taken by a member of the Expedition 42 crew. The image has been cropped and enhanced to improve contrast, and lens artifacts have been removed.


• March 23, 2015: ESA astronaut Samantha Cristoforetti took these two images (Figure 26) from the International Space Station during her six-month mission. The Progress cargo ship and Soyuz crew spacecraft reflect sunlight as our star sets behind Earth. Samantha commented on the pictures: "Before the orbital night embraces our outpost in space this cold metallic light shines on the Space Station." 24)

- The colors appear as sunlight slices through the atmosphere. Light with shorter wavelengths is scattered by oxygen in the air first and appears blue. If sunlight hits the atmosphere at a low angle, it travels further through the air and more blue light is filtered out, creating the redder hue.


Figure 26: A sunset happens quickly in orbit – these two images (left and right) were taken on March 3, 2015 just two minutes apart before the Sun disappeared, returning just 45 minutes later (image credit, ESA, NASA)

Legend to Figure 26: Traveling at 28 800 km/h, astronauts can enjoy a sunset and sunrise 16 times a day as they circle our planet in the Space Station.


• March 16, 2015: Astronauts of the Expedition 42 crew, flying on the International Space Station, took this photograph of California's southernmost coastal city. The mouth of San Diego Bay, between North Island and the Point Loma peninsula, is just over a kilometer wide. The rocky coast near Point Loma appears jagged compared to the smooth curve of the sandy beach on North Island. - Despite some thin clouds, the image shows port facilities and the San Diego International Airport. Near the mouth of the bay, numerous civilian boats occupy the marinas at Shelter Island and Harbor Island (south and southwest of the airport). 25)

• NASA astronauts Terry Virts and Barry Wilmore ended their spacewalk at 17:30 UTC on March 1, 2015 with the repressurization of the Quest airlock. Wilmore and Virts accomplished all planned objectives and one get-ahead task within a Phased Elapsed Time (PET) of 5 hours 38 minutes. Cristoforetti and Shkaplerov assisted during suit donning and doffing activities. The Joint Airlock egress took place at 6:52 UTC and post EVA hatch closure at 12:27 UTC. Objectives accomplished during today's EVA are as follows:27)

- P3 C2V2 Boom, Antenna, and Retro-Reflector Install

- All activities are completed unless otherwise noted.

Background: The ISS program managers and engineers are working on long-term plans to support future crew and cargo vehicles, including the installation of a new docking system onto the station for use by future commercial crew vehicles, along with the relocation of some Station modules, in order to free up ports for use by future crew and cargo spacecraft. - In preparation for the arrival of new commercial crew vehicles to the ISS in late 2017 – which will use a brand new docking system – the existing docking ports on the ISS need to be converted to the new standard, before any commercial crew vehicles can dock to the outpost. 28)

Currently, the station has one usable port for docking – Pressurized Mating Adapter-2 (PMA-2) located on the Forward end of the Node 2 module. Another PMA (PMA-3) is also on the ISS, however in its current location (the Port side of Node 3) it is inaccessible for docking.

Both PMA-2 and PMA-3 feature a Russian-designed APAS (Androgynous Peripheral Attachment System) docking interface as was used by the now retired Space Shuttle fleet.

However, the new fleet of commercial crew vehicles currently planned to begin arriving at the ISS in 2017 will use a new docking interface, known as the NDS (NASA Docking System).

In October 2010, the ISS international partners met to agree on a new IDSS (International Docking System Standard), which rather than being a specific docking system, was simply a standard to which any country or company could design their own docking system to. Hence, NASA's implementation of the IDSS became known as the NASA Docking System (NDS).

The current (2015) plan of NASA is to fly two IDAs (International Docking Adapters) to the ISS, which will attach to the two PMAs in order to convert their APAS interfaces into SIMAC (Soft Impact Mating Attenuation Concept) interfaces, which in turn will be used by all future commercial crew vehicles.

- SpaceX CRS-7 is a cargo resupply mission to the ISS planned for launch in June 2015. The IDA-1 is scheduled to be delivered to the International Space Station on CRS-7. This adapter will be attached to one of the existing PMAs (Pressurized Mating Adapters) ,specifically, PMA-2 or PMA-3, and convert the existing APAS-95 docking interface to the new NASA Docking System (NDS). The new adapter is intended to facilitate future docking of new US human-transport spacecraft. Previous US cargo missions since the retirement of the Space Shuttle have been berthed, rather than docked, while docking is considered the safer and preferred method for spacecraft carrying humans.

NASA is introducing IDSS (International Docking System Standard) to promote interoperability. The goal is to enable exploration collaboration between partners using different spacecraft. Two IDAs were developed for implementation on the International Space Station. 29)

Boeing is the primary contractor for the IDAs (International Docking Adapters) and the adapters were assembled at their Houston Product Support Center.


ISS (International Space Station) Mission Control Centers:

1) MMC-H (Mission Control Center-Houston) of NASA/JSC (Johnson Space Center) is responsible for overall mission control of the ISS . MCC-H has overall authority and responsibility for the safety of the ISS and crew, planning and plan execution, systems operations, and anomaly troubleshooting. The MCC-H FD (Flight Director) leads the real-time execution and will receive status information from the various control centers on significant Station operations activities which are being conducted. The MCC-H FD approves all MCC-H commands to the Station, and the initiation of any potentially hazardous operation.

2) POIC (Payload Operations and Integration Center) of NASA/MSFC (Marshall Space Flight Center), Huntsville, AL. POIC is the headquarters for International Space Station science operations. This Control Center links Earth-bound researchers and developers from around the world with their experiments and astronauts aboard the ISS. The role of POIC has become ever more important since space station assembly was completed in the fall of 2011. Since 2001, the center has worked with thousands of scientific investigators from around the world to perform scientific research in a variety of disciplines from astrophysics to human research to technology demonstrations to help future space explorers.

3) TsUP (Mission Control Center Moscow for International Space Station), Korolov City, Moscow Region. TsUP is the primary Russian facility for the control of human space flight; it is responsible for the launch, rendezvous, docking, assembly and control of the Russian elements. In coordination with NASA, it directs ISS component launch activities at the Baikonur Cosmodrome in Kazakhstan. RSC Energia (S. P. Korolov Rocket and Space Corporation Energia) integrates spacecraft hardware and manages the ISS Program implementation for the Russian segment. Roscosmos, the Russian Federal Space Agency, oversees all Russian human space flight activities.

4) ESA (European Space Agency) has two ground control centers for control to operate the European contributions to the International Space Station. These are the Col-CC (Columbus Control Center) at DLR in Oberpfaffenhofen, Germany and the ATC-CC (Automated Transfer Vehicle Control Center), at CNES in Toulouse, France. Col-CC controls and operates the Columbus laboratory and coordinates European experiments while ATV-CC controls and operates the European ATV spacecraft.

5) SSIPC (Space Station Integration & Promotion Center) of JAXA (Japan Aerospace Exploration Agency) at the TKSC (Tsukuba Space Center), Ibaraki prefecture, Japan. The SSIPC is responsible for the Japanese elements of the ISS involving in particular the operation of JEM/Kibo and of the HTVs (H-II Transfer Vehicles) of JAXA as well as the coordination with MCC-H.

1) A Soyuz vehicle flew the first crew to the ISS in Nov. 2000 (launch on Oct. 31. 2000). Since that time, at least one Soyuz has always been at the Station, generally to serve as a lifeboat should the crew have to return to Earth unexpectedly.

- Up to three crew members can launch and return to Earth from the Station aboard a Soyuz TMA spacecraft.

- A new Soyuz capsule is normally delivered to the station by a Soyuz taxi crew every six months - the taxi crew then returns to Earth in the older Soyuz capsule.

- A Soyuz spacecraft generally takes two days after launch to reach the space station. The rendezvous and docking are both automated. The Russian Mission Control Center monitors the close approach maneuvers to the ISS.

- A modernized Soyuz TMA-M of Roscosmos is used since 2010. The TMA-01-M (launched on Oct. 7, 2010) was the 107th flight of a Soyuz spacecraft, and the first flight of the modernized TMA-M series to the ISS.

• Feb. 3, 2015: There's an oft-used idiom that you can't see political borders from space, but we've known for a while it's no longer true. Between higher resolution cameras and the increase in human activity, there have been several examples of borders visible from space (Figure 33). 32)


Figure 33: This image, taken by astronauts on the ISS on Nov. 7, 2014, shows patterns of fortification along the Iraq-Iran border (image credit: NASA/Expedition 41)

Legend to Figure 33: Astronauts aboard the ISS took this photograph in November of 2014 of a 20 km stretch of the Iraq-Iran border, near the coast of the Persian Gulf. Clearly visible is the border between the two countries, along with signs of fortification: circular gun emplacements, systems of large curved earthworks and straight connecting roads that run parallel to the border.

NASA said the ISS team that analyzes astronaut photos first thought the circular features to be oil-pad installations . But they said the "strategic location of these formations along the international boundary made it easier to see these as patterns of military fortifications. This region of oil refining and exporting was the center of numerous military actions during the war in the 1980s, especially during the defense of the southern city of Basra."

• Figure 35, released on January 27, 2015, lightning illuminates the area it strikes on Earth but the flash can be seen from space, too. This image was taken from 400 km above Earth in 2012 by an astronaut on the ISS travelling at 28,800 km/h. At these distances a camera flash is pointless to take night-time images of Earth, but our planet moves by so quickly images can end up being blurred. 34)

- ESA's Nightpod camera aid compensates for the motion of the Station, allowing for crystal-clear night images such as these. The target stays firmly centered in the frame, so the final image is in focus. Astronauts can set up the device to take ultra-sharp images automatically using off-the-shelf cameras. — Nightpod is an intelligent tripod head that is used to accurately track a SLR (Single Lens Reflex) camera, potentially with a large SLR, to track objects. Extremely sturdy and user friendly, it can be used to take long exposure photographs or eliminate motion blur under demanding conditions. It can be used for accurate tracking of moving objects or track stationary objects from a moving platform, such as boats, airplanes and cars.

• January 14, 2015: A false alarm of the thread of a possible ammonia leak forced the crew into a middle of the night evacuation from the US side of the International Space Station, and a hatch closure. Nearly 12 hours later, top level managers from the partner space agencies gave the all clear and allowed the astronauts and cosmonauts to reopen access to the American portion of the orbiting outpost. The six person crew was allowed to open the sealed hatch to the U.S. segment later in the day after it was determined that the ammonia leak was quite fortunately a false alarm. No ammonia leak was actually detected. But the crew and mission control had to shut down some non essential station systems on the US segment in the interim. All the Expedition 42 crew members were safe and in good health and never in danger, reported NASA. 35)

- The alarm is part of the environmental systems software on the station designed to monitor the cabin's atmosphere. At the same time, the station's protection software shut down one of two redundant cooling loops (Thermal Control System Loop B). Ammonia is a toxic substance used as a coolant in the stations complex cooling system that is an essential requirement to continued operation of the station. - Meanwhile, flight controllers are continuing to analyze data in an effort to determine what triggered the alarm that set today's actions in motion.

- The evacuation came just two days after a commercial SpaceX Dragon cargo freighter, CRS-5 (Commercial Resupply Service-5), successfully rendezvoused and berthed at the station on Jan. 12., 2015. The crew had just opened the hatch to Dragon and begun unloading the goodies stored aboard.

- According to a NASA report, the flight controllers in Mission Control at NASA/JSC (Johnson Space Center) in Houston saw an increase in pressure in the station's water loop for thermal control system B then later saw a cabin pressure increase that could be indicative of an ammonia leak in the worst case scenario. Acting conservatively to protect for the worst case scenario, the crew was directed to isolate themselves in the Russian segment while the teams are evaluating the situation. Non-essential equipment in the U.S. segment of the station was also powered down per the procedures. 36)

Figure 37: Human spaceflight and operations image of the week: chemistry creating hollow structures in space (image credit: NASA, Roscosmos)

Legend to Figure 37: Polymers are repeated molecules that form many materials we use every day, such as rubber and nylon. Rubber is a natural polymer but polymers can also be created synthetically using chemical reactions to string together monomers into new structures. In the weightlessness of space, these reactions can be tailored to create polymer walls that form shells. The experiment demonstrates this method of creating polymers in space as well as improving computer models and offering a striking illustration of physics and chemistry in action for educational purposes.

The experiment is being run in a contained glovebox and features two hardening processes to ‘set' the end structures.


• Figure 38 is an ISS astronout photo showing the city of Vancouver and its greater sourroundings in British Columbia, Canada. The Fraser River winds for almost 1,400 km, making it the longest river in this Canadian province. Snowmelt feeds the river, which flows alongside the Rocky Mountains to a relatively flat plateau. The Fraser continues down through the Coast Mountains and the Fraser Canyon until reaching a 130 km wide floodplain that empties into the Strait of Georgia. 38)

Along its journey, the river picks up and carries a huge load of silt—about 20 million tons each year. Most of it flows into the Strait of Georgia, while about 3.5 million tons is left behind and deposited in the lower river valley. The silt gives the river a milky color; this effect is most pronounced at the river's mouth, where the freshwater plume is visible even from space.

Those silty sediments do not travel alone. They carry nutrients that support phytoplankton growth into the strait and the ocean (blooms of phytoplankton can also impart a blue, green, or milky color to the water). These blooms become the center of a food web for grazers like the sockeye salmon that hatch in the Fraser. Those nutrients are recycled back to the Fraser when the salmon return four years later to spawn.

• January 3, 2015: It's sunrise from space – one of 16 that occur daily as the massive lab complex orbits the Earth about every 90 minutes while traveling swiftly at about 28,100 km/h from an altitude of about 400 km (Figure 39). The Canadian-built robotic arm, Canadarm 2, used among other things to catch visiting spacecraft (Dragon, Cygnus, HTV), subtends in the middle of the picture through which the rising sun is seen. 39)

• Dec. 9, 2014: Figure 40 is an image of ESA's ATV-5 (Automated Transfer Vehicle-5), named Georges Lemaître, as seen from the International Space Station as it approaches for docking in August 2014. 40)

- ATV Georges Lemaître demonstrated a set of European sensors that offers future improvements on the autonomous rendezvous and docking that these ferries have completed five times since 2008. ESA's goal is to perform an automated rendezvous further from home – perhaps near Mars or with an ‘uncooperative' target such as an inert object.

- Seeing through the eclipse: During Georges Lemaître's rendezvous using its proven system, the LIRIS (Laser Infrared Imaging Sensors) experiment was turned on some two and a half hours and 3500 m from the Space Station. All of the sensors worked as expected and a large amount of data was recorded and stored on hard disks in ATV's cargo hold. The disks were retrieved by ESA astronaut Alexander Gerst on August 29, 2014 and returned to Earth in Soyuz TMA-12M in September. The information is now being compared against the results from ATV's normal navigation sensors.

- With ATV-5 pointing directly at the Station, the LIRIS infrared cameras tracked the weightless research center perfectly despite several 30-minute periods in darkness when the Sun was eclipsed by Earth and traditional cameras would have gone blind.

- The image (Figure 41) was taken 70 m from the Station – the first showing the complex in this configuration. Ahead of an ATV docking, the Station turns its solar wings to avoid GPS navigation signals bouncing off the structure and confusing the incoming craft.

- LIRIS is a test of European sensors technology in space to improve the autonomous rendezvous and docking that ATVs have performed five times since 2008. ESA's goal is to be able to perform an automated rendezvous far from home, perhaps in Mars orbit or with an uncooperative target such as an inert object.

- Four days before docking, ATV flew 7 km below the Station to check the long-range capability of the infrared cameras. A first look at the readings confirms LIRIS' ability to track targets from a distance.

LIRIS includes a lidar – like a radar but using light – that pulses laser beams over a mirror to collect 3D data at high resolution. The lidar also registers the amount of reflected light, which can provide clues on the type of material it is scanning. The advantage of the LIRIS approach is that it scans objects and gathers information about them without a dedicated communications link or hardware installed on the targets.

Legend to Figure 42: The image on the left shows how far each element of the Space Station is from ATV-5 with arbitrarily chosen colors corresponding to their distance from LIRIS. The Russian service module, to which Georges Lemaître docked, shows up in green at a distance of 30 m, while the Soyuz was 15 m away and shows in yellow (top). The main truss of the Station is represented in purple at 40 m. - The image on the right was created from the same data but shows how much light was reflected at each point. The Station's retroreflector used for ATV's normal laser docking sensors shows up brightly, just as the designers intended. 42)


• December 2014: ISS maneuvers throughout its initial orbital life of 15 years. — November 2013 marked 15 years of the Functional Cargo Block (FGB) Zarya launch into orbit. It was the first element of the ISS (International Space Station). In this period, the ISS has evolved into the largest man-made space structure created in the history of space. If we compare all the vehicles in LEO, the ISS beats the record in the number of the performed maneuvers that differ in purpose, size, propulsion system, etc. Systematization of the ISS maneuvers is supplemented with statistical data of various parameters. The evolution of maneuvering strategies during the different ISS life cycles, starting from FGB insertion into orbit up to the present, is provided. 43)

At the present time, the ISS with a total mass of about 410 tons is the largest object in space. One of the most important outcomes of the ISS Program is the establishment of reliable international cooperation that implements the orbiting complex utilization.


Figure 43: Altitude profile of the ISS and the index of solar activity: F10.7 (image credit: Rocket Space Corporation Energia, Russia)

Operation of such complex object requires maintaining the orbit according with a preselected altitude profile. The orbit of the ISS is continuously being reduced from aerodynamic drag; the rate of altitude loss depends on the current orbital altitude as well as on the intensity of solar radiation, which has an 11-year cycle and determined by index of solar activity , referred to as F10.7 and corresponds to the density flux of solar radio emission at a wavelength of 10.7 cm. Without timely maneuvering, any space object in LEO will suffer a quick reentry into Earth's atmosphere. Hence, frequent reboosts are needed to maintain the selected altitude. The planning of these reboosts must take into consideration many aspects regarding the current operational (zero-g) environment required for experimentation, as well as the ballistic conditions for a rendezvous of visiting vehicles and the landing of human spacecraft in a given area of the Earth. In particular, more frequent debris avoidance maneuvers are needed for the safety of the crew and of the station.

Analyzing the altitude profile, together with the index of solar activity, F10.7, the first 15 years of the ISS can be divided into 5 periods of operational activity (Figure 43):

2) Initial phase from delivering the FGB Zarya into orbit until the launch of the Service Module (SM) Zvezda (1998-2000). In this phase, the ISS was in automatic unmanned mode, except for the short missions. A total of 22 reboosts were were carried out using propulsion of the FGB and the Shuttle. An altitude range of 350-370 km was maintained.

3) The first stage of the ISS build-up up to the STS Columbia (2000-2003) accident. By the end of 2002, more than 13 Shuttle flights were conducted with large-size payloads. The ISS was in an altitude range of 380-390 km and the solar flux index F10.7 value was high. The altitude profile was maintained by the Shuttle and by Progress vehicles.

4) This was followed by a 2 1/2 year period, in which all Shuttle flights were suspended due to the Columbia accident on Feb. 1, 2003. It reduced the intense build-up phase of the station. During this phase, ISS operation were only maintained by the Russian MS Soyuz-TMA and CS Progress-M.

5) The resumption of Shuttle flights occurred July 26, 2005 with STS-114. The Shuttle flights continued until 2011; the return flight of STS-135 ended the era of Shuttle flights on July 21, 2011 after which the US segment of the ISS reached its desired configuration. During this period, the ISS orbit was lowered to 340-350 km. In the last Shuttle flight to the ISS, the STS-135 docked at an altitude of ~380 km.

6) In the current phase (2011-2014) the ISS is serviced mostly by Russian space vehicles (Soyuz and Progress). Russian CS (Cargo Ships) Progress-M, European ATV, Japanese HTV and two private CS Dragon (SpaceX) and Cygnus (OSC).

The entire ISS complex can be maneuvered, or re-oriented, by firing Russian rocket thrusters or by changing the speed of NASA's gyroscopes inside the Z1 truss atop the Unity module. Rocket thrusters are typically used for major maneuvers while the gyros are primarily used for more minor attitude changes. 44)


• Nov. 17, 2014: The Florida peninsula at night is highly recognizable in this photo of Figure 44, taken by the ISS Expedition 41 crew. The illuminated areas give a strong sense of the size of cities. The brightest continuous patch of lights is the Miami-Fort Lauderdale metropolitan area, the largest urban area in the southeastern U.S. and home to 5.6 million people. The next largest area is the Tampa Bay region (2.8 million people) on the Gulf Coast of the peninsula. Orlando, located in the middle, has a somewhat smaller footprint (2.3 million). A nearly straight line of cities runs nearly 560 km along the Atlantic coast from Jacksonville, Florida, to Wilmington, North Carolina. 45)

South of Orlando, the center and southern portions of the peninsula are as dark as the Atlantic Ocean, vividly illustrating the almost population-free Everglades wetland. The lights of Cocoa Beach trace the curved lines of Cape Canaveral and the Kennedy Space Center, an area well known to astronauts. Dim lights of the Florida Keys extend the arc of the Atlantic coast to the corner of the image. The small cluster of lights far offshore is Freeport on Grand Bahama Island (image right). The faint blue areas throughout the image are clouds lit by moonlight.

The rear astronauts are dressed in the Sokol suits they will wear in their Soyuz spacecraft that will take them back to Earth on 9 November. Alexander, Max and Reid were making sure their suits still fit and have no leaks after having been stored on arrival at the Station almost six months ago.

Yelena, Alexander Samokutyaev and Barry will continue working in the weightless research center, but they will not feel lonely for long. ESA astronaut Samantha Cristoforetti, NASA astronaut Terry Virts and Roscosmos cosmonaut Anton Shkaplerov will join their colleagues on 24 November, 2014.


• ESA astronaut Alexander Gerst shared the photos of Figures 46 and 47 on social media with the comment: "Safe to say, this was the most amazing thing I have done in my life. The pump module I carry here has a mass of nearly 400 kg. I could move it with my little finger." 47)

Alexander spent six hours and 13 minutes outside the International Space Station with NASA astronaut Reid Wiseman on October 7, 2014. This was the first spacewalk for both astronauts but they performed well in the weightlessness of orbit. The pair worked together to move a 385 kg pump from the Station's truss to a permanent stowage location near the US Destiny module.

While moving, Alexander held on to the pump unit with flexed arms to absorb any shocks. After working with Reid to attach the pump, Alexander took the arm for a last ride to park it and prepare it for its next use, berthing visiting spacecraft. Here, Alexander had his hands free and time to take a few photographs, such as this one. Alexander's feet are strapped to the arm and tethers secure him to the arm. To the right is the commercial Dragon supply vessel.

Alexander then helped Reid upgrade the power relay on a trolley before they returned to the airlock at 18:34 GMT.

Figure 47: Photo of a spacewalker at work on the International Space Station on Oct. 7, 2014. "I don't have words to describe what we did today, but this photo gives a pretty good impression!" wrote European Space Agency astronaut (and spacewalk participant), Alexander Gerst, Universe Today 48)

Legend to Figures 46 and 47: The two spacewalkers worked outside the Quest airlock of the International Space Station for 6 hours and 13 minutes. Flight Engineer Barry Wilmore NASA operated the Canadian robotic arm (Canadarm2), maneuvered Gerst during the course of the spacewalk and served as the spacewalk coordinator. 49)

The first task for Wiseman and Gerst was relocating a failed cooling pump to ESP-2 (External Stowage Platform-2) just outside the Quest airlock. It was temporarily stowed on the station's truss by Expedition 38 spacewalkers Mike Hopkins and Rick Mastracchio on Dec. 21, 2013, after they replaced the failed pump with a spare.

When they completed the pump module stowage work, the duo stowed adjustable grapple bars on ESP-2. Wiseman cleaned up the work area around the pump module. Gerst went on to replace a light on an ETVCG (External Television Camera Group) outside of Destiny.

The next task was the installation of a MTRA (Mobile Transporter Relay Assembly) on to the S0 truss right above the Destiny laboratory. The MTRA adds the capability to provide "keep-alive" power to the Mobile Servicing System when the Mobile Transporter is moving between worksites.

The Mobile Transporter can move supplies, gear and the Canadarm2 on rails along the Integrated Truss Structure, the station's backbone. The Mobile Servicing System, which includes the transporter and Canadarm2, plays a key role in station maintenance tasks.


• Sept. 23, 2014: After the launch of the SpaceX-CRS-4 (Commercial Resupply Services-4) Dragon capsule from Cape Canaveral on Sept. 21 (05:52:03 UTC) and a two day chase through space, the Dragon cargo capsule arrived at the ISS, following a carefully choreographed series of thruster firings that brought the vessel to within a capture distance of some 10 m. For the rendezvous, ESA astronaut Alexander Gerst and NASA astronaut Reid Wiseman had set up a temporary robotics workstation in the Station's Cupola observatory module to monitor the approaching commercial spacecraft until it stopped 10 m from the Station. Working two joysticks, Alexander moved Canadarm2 to hold Dragon-4 as the Station soared some 415 km above the Pacific Ocean. From there, the spacecraft was berthed to the Space Station's Harmony module. 50) 51) 52)

On Sept. 24, the hatch will be opened to unload the ~2270 kg of supplies and payloads. Dragon will stay for four weeks before it returns to Earth with experiments and samples.

ATV-5 was the heaviest spacecraft ever launched by Ariane 5 with a launch mass of 20,275 kg.

During its trip to the ISS, ATV-5 flew about 6 km below the space station on Aug. 8, to test sensors for potential use on future European spacecraft before beginning the final phase of its rendezvous with the orbital laboratory.

The fifth ATV, and final space freighter in the series, is designated Georges Lemaître (1894-1966) after the Belgian physicist (Catholic priest and astronomer) and father of the Big Bang theory (published in 1927). The ATV-5 is expected to remain docked until late January 2015. During its stay at the station, the ATV-5 will serve as an exercise facility for the astronauts in addition to performing maneuvers that maintain this manned facility's nominal orbit and testing new rendezvous sensors in space.

- LIRIS (Laser InfraRed Imaging Sensors). LIRIS is a first step towards an uncooperative rendezvous in space. 55)

- An ESA-led team designed and developed the BUC (Break-Up Camera) for the ATV-5 mission as well as the Reentry SatCom capsule to work like an aircraft-style 'black box' to store images, then transmit them to Earth after the vessel's break-up via an Iridium satellite link. ESA's BUC camera will join Japan's i-Ball optical camera and NASA's Reentry Break-up Recorder, to give as full a picture as possible of the conditions inside the vehicle as it breaks up. The BUC infrared camera, bolted to an ATV rack, will burn up with the rest of the spacecraft, but imagery of the final 20 seconds will be passed to the Reentry SatCom, a spherical capsule protected by a ceramic heat shield. 56)

The Reentry SatCom has an antenna, so that once the ATV breaks up, it begins transmitting the data to any Iridium communication satellites in line of sight. The break-up will occur at an altitude of about 80–70 km on reentry, leaving the Reentry SatCom falling at 6–7 km/s. The fall will generate a high-temperature plasma around it, but signals from its omnidirectional antenna should be able to make it through any gap in the plasma to the rear. Additionally, it is expected that signalling will continue after the atmospheric drag has decelerated the SatCom to levels where a plasma is no longer formed – somewhere below 40 km – at a point where Iridium satellites should become visible to it regardless.


• The astronaut photograph ISS040-E-74022 (Figure 53) was acquired on July 22, 2014, and released on August 18, 2014. It shows the location and size of cities at the east end of the Mediterranean Sea. The largest, brightest cluster is the Israeli city of Tel Aviv, a port set against the blackness of the Mediterranean Sea. Jerusalem, Israel's capital city, and Amman, Jordan's capital, are the next largest (with Amman's lights having a whiter tone), followed by Beersheba. 57)

- Bright but narrow lines that snake between the cities are highways. The mostly dark areas with small towns are agricultural and pastoral areas of Israel, Sinai, Gaza, the West Bank, and Jordan. A wide, almost black zone between Jerusalem and Amman trends north-south across the right half of the image; it is the long valley that includes the Jordan River and the Dead Sea.

Legend to Figure 57: Banks Peninsula is a peninsula of volcanic origin on the east coast of the South Island of New Zealand. It has an area of approximately 1,150 km2 and encompasses two large harbours and many smaller bays and coves. The South Island's largest city, Christchurch, is located immediately north of the peninsula. - The crew of Captain James Cook became the first Europeans to sight the peninsula on February 17, 1770, during Cook's first circumnavigation of New Zealand.


• On May 29, 2014, the expedition 40/41 crew (NASA astronaut Reid Wiseman, ESA astronaut Alexander Gerst, Roscosmos commander Maxim Suraev) arrived at the ISS in their Soyuz spacecraft. They complement the three crewmembers on board since April and will stay in their new home in space for almost six months. Immediately after arrival, they held a short conference with family and friends on Earth who they had left behind only six hours earlier. Alexander and Reid were taken on tours of the Station – the size of a large six-bedroom house – and shown how the systems work by Station commander Steve Swanson. General maintenance and emergency procedures were run through for the new arrivals. 61)

• March 2014: An astronaut on the International Space Station took this night photograph (Figure 60) of two of Belgium's major metropolitan areas. Antwerp is a major European port located on the Scheldt River, which appears as a black line angling through the lights. The city has access to the Atlantic Ocean, and its extensive dock facilities are even more brightly lit than the city center. 64)

Brussels is the capital and largest city in Belgium, and also the de facto headquarters of the European Union. Brilliant points of light are the city center and the Brussels National Airport. Developed roadways appear as straighter, brighter lines radiating from the two cities.

The photos of Figures 60 and 61 were taken with a Nikon D3S digital camera, and are provided by the ISS Crew Earth Observations Facility and the Earth Science and Remote Sensing Unit, Johnson Space Center.

• April 14, 2014: The Grand Canyon in northern Arizona is a favorite for astronauts shooting photos from the International Space Station, as well as one of the best-known tourist attractions in the world. The steep walls of the Colorado River canyon and its many side canyons make an intricate landscape that contrasts with the dark green, forested plateau to the north and south. 65)


Figure 62: This astronaut photograph of the Grand Canyon from the ISS was acquired on March 25, 2014, with a Nikon D3S digital camera using a 180 mm lens, and is provided by the ISS Crew Earth Observations Facility and the Earth Science and Remote Sensing Unit, Johnson Space Center (image credit: NASA)

Legend to Figure 62: The Grand Canyon has become a geologic icon—a place where you can almost sense the invisible tectonic forces within the Earth. The North and South Rims are part of the Kaibab Plateau, a gentle tectonic swell in the landscape. The uplift of the plateau had two pronounced effects on the landscape that show up in this image. First, in drier parts of the world, forests usually indicate higher places; higher altitudes are cooler and wetter, conditions that allow trees to grow. The other geologic lesson on view is the canyon itself. Geologists now know that a river can cut a canyon only if the Earth surface rises vertically. If such uplift is not rapid, a river can maintain its course by eroding huge quantities of rock and forming a canyon.


• April 2014: It used to be that building and launching a working satellite was an enormously expensive and complex undertaking, feasible only for governmental and military agencies. But the CubeSat revolution of the past decade has placed satellite technology within reach of private companies, universities and even unaffiliated individuals. That revolution has been boosted by the existence of the International Space Station, which provides an additional launching platform enabled through regular commercial cargo flights. 66)

At present, two CubeSat deployers operate aboard the station: the Japanese Experiment Module J-SSOD (JEM - Small Satellite Orbital Deployer) and the NanoRacks CubeSat Deployer. The upcoming launch of the SpaceX-4 commercial resupply mission, currently scheduled for September 2014, will enhance the space station's satellite deployment capabilities with the delivery of Cyclops, also known as SSIKLOPS (Space Station Integrated Kinetic Launcher for Orbital Payload Systems) . This tool will provide still another means to release other small satellites, namely microsatellites of all shpes, from the orbiting outpost.

• March 31, 2014: The Kavir desert (Dasht-e Kavir – literally ‘desert of salt-marsh') in Iran, was photographed by astronauts from the ISS in February 2014. Figure 64 displays a striking pattern of parallel lines and sweeping curves. The lack of soil and vegetation in the Kavir desert allows the geological structure of the rocks to appear quite clearly. The patterns result from the gentle folding of numerous, thin layers of rock. Later erosion by wind and water cut a flat surface across the dark- and light-colored folds, not only exposing hundreds of layers but also showing the shapes of the folds. The pattern has been likened to the layers of a sliced onion. 67)


Figure 64: The Kavir desert in Iran, as seen from the International Space Station on Feb. 14, 2014 (image credit: NASA)

Legend to Figure 64: The image, taken by the Expedition 38 crew, was acquired with a Nikon D3 digital camera using a 200 mm lens, and is provided by the ISS Crew Earth Observations Facility and the Earth Science and Remote Sensing Unit, NASA/JSC (Johnson Space Center).

The dark water of a lake (image center) fills a depression in a more easily eroded, S-shaped layer of rock. The irregular, light-toned patch just left of the lake is a sand sheet thin enough to allow the underlying rock layers to be detected. A small river snakes across the bottom of the image. In this desert landscape, there are no fields or roads to give a sense of scale. In fact, the width of the image is about 105 km.


• On March 25, 2014, the onboard ISS crew (Expedition 39) spotted the launch of the Expedition 40 crew at 21:17 UTC as their Soyuz TMA-12M vehicle took off from the Baikonur Cosmodrome in Kazakhstan. 68)

• On March 17, 2014, NASA released an astronaut snapshot of Bowknot Bend of the Green River canyon in eastern Utah (Figure 66). The loop carries river rafters 14.5 km before bringing them back to nearly the same point they started from—though on the other side of a low, narrow saddle (image center). 69)


Figure 66: An astronaut image acquired on January 22, 2014 showing Bowknot Bend of the Green River in Utah. The photo was taken by the Expedition 38 crew using a Nikon D3X digital camera using a 1000 mm lens (image credit: NASA)

Legend to Figure 66: In this snapshot from the ISS, the Green River appears dark because it lies in deep shadow, 300 m below the surrounding landscape. The yellow-tinged cliffs that face the rising sun give a sense of the steep canyon walls. The straight white line across the scene is the contrail from a jet liner that passed over Bowknot Bend. Note that north is to the bottom of the image.

The reason for the tight bends in the Green River is the same as it is for the Mississippi: river courses often wind over time when they flow across a bed of relatively soft sediment in a floodplain. Geologists assume that the Green River, before its present canyon phase, once snaked across a wide valley on a bed of its own sediment and made a series of striking meander bends. Vertical uplift of the entire landscape—by deep-seated tectonic forces related to the growth of the Rocky Mountains—caused the Green River to erode downwards into the hard rocks under the valley. In the process, the present vertical-sided canyon was formed, preserving the tight loops reminiscent of an earlier time.

Bowknot was named by geologist John Wesley Powell in 1869 during one of his famous explorations of the rivers in the American West. The Green River flows south (toward the top of this image) and joins the Colorado River downstream. The combined flow of these rivers was responsible for cutting the Grand Canyon, some 325 km away from Bowknot.


• On March 11, 2014, ESA released a snapshot (Figure 67) taken from the Cupola of the ISS of ESA's EAC (European Astronaut Center), collocated at the DLR German Aerospace Center site at Cologne-Bonn. 70)

• The image of Figure 68, Iberian Peninsula, is from the "week in images" March 3-7, 2014. The lights from human settlements reveal where the major towns and activity are. The large mass of light in the middle is Madrid, Spain's capital city. The Iberian coastline is heavily populated with Valencia and Barcelona along the Mediterranean Sea prominent at the bottom right of this photo. Portugal to the west shows similar lighting with the coast from Lisboa to Porto a haze of light. 71)

Legend to Figure 68: The astronaut-image taken from 400 km above Earth shows how close the Iberian Peninsula is to Morocco. A thin line of blackness – the Strait of Gibraltar – separates the two. Another thin line stands out in this picture – Earth's atmosphere, the green shroud that surrounds and protects our world and the people and animals that live on it. The image was taken using ESA's NightPod camera mount.


• Feb. 24, 2014: Flying over East Asia, astronauts on the International Space Station (ISS) took this night image of the Korean Peninsula. Unlike daylight images, city lights at night illustrate dramatically the relative economic importance of cities, as gaged by relative size. In this north-looking view, it is immediately obvious that greater Seoul is a major city and that the port of Gunsan is minor by comparison. There are 25.6 million people in the Seoul metropolitan area—more than half of South Korea's citizens—while Gunsan's population is 280,000. 72)


Figure 69: The Koreas at Night photographed from the ISS on Jan. 30, 2014 (image credit: NASA Earth Observatory, the image was released on Feb. 24, 2014)

Legend to Figure 69: North Korea is almost completely dark compared to neighboring South Korea and China. The darkened land appears as if it were a patch of water joining the Yellow Sea to the Sea of Japan. Its capital city, Pyongyang, appears like a small island, despite a population of 3.26 million (as of 2008). The light emission from Pyongyang is equivalent to the smaller towns in South Korea.

Coastlines are often very apparent in night imagery, as shown by South Korea's eastern shoreline. But the coast of North Korea is difficult to detect. These differences are illustrated in per capita power consumption in the two countries, with South Korea at 10,162 kW hours and North Korea at 739 kW hours.

The Astronaut photograph ISS038-E-38300 was acquired on January 30, 2014, with a Nikon D3S digital camera using a 24 mm lens (the camera is mounted on ESA's NightPod), and is provided by the ISS Crew Earth Observations Facility and the Earth Science and Remote Sensing Unit, Johnson Space Center. 73)


• February 2014: Three months after bearing the Olympic torch outside their orbiting home, the astronauts and cosmonauts on the International Space Station (ISS) got to look down on that flame from above. On the evening of February 10, 2014, an Expedition 38 crew member on the ISS captured this digital photograph of Sochi, Russia, along the coast of the Black Sea (Figure 70). 74)


Figure 70: Sochi at night as photographed from the ISS (image credit: NASA Earth Observatory, the image was released on Feb. 17, 2014)

Legend to Figure 70: Astronaut photograph ISS038-E-42992 was acquired on February 10, 2014, with a Nikon digital camera using a 600 millimeter lens, and is provided by the ISS Crew Earth Observations Facility and the Earth Science and Remote Sensing Unit, Johnson Space Center. The image was taken by the Expedition 38 crew.

In the image, the Olympic flame now burns in the circular Medals Plaza, ringed in gold and bright white lighting in the center of the Olympic Park. The oval-shaped Fisht Olympic Stadium is lit in blue and stands near the shore to the south (south is to the right in the image). The Adler Arena Skating Center and the Iceberg Skating Palace both appear as black rectangles north and east of the Medals Plaza, and the Bolshoy Ice Dome has a pink tint and stands to the west.

Sochi is a city of nearly 340,000 people in Krasnodar Krai, Russia, near the border between Georgia and Russia. Warmed by the Black Sea and straddling the continents of Europe and Asia, the resort city has a subtropical climate that draws many tourists. It is one of the warmer locations ever chosen for the Winter Games. However, snow coats the slopes of the Caucasus Mountains just 40 km inland.


• The Cygnus CRS-1 (Cargo Resupply Mission-1), or Cygnus CRS Orb-1, also known as Orbital Sciences CRS Flight 1, is the second flight of the Orbital Sciences' unmanned resupply spacecraft Cygnus, its second flight to the ISS (International Space Station) and the third launch of the company's Antares launch vehicle. The flight is the first of 8 under the CRS (Commercial Resupply Services) contract to NASA and is also referred to as COTS (Commercial Orbital Transportation Services).

The Cygnus Orb-1 mission was launched on January 9, 2014 on an Antares-120 Vehicle of OSC from MARS (Mid-Atlantic Regional Spaceport), Wallops Island, VA.

The cargo craft was loaded with 1261 kg supplies for the station, including vital science experiments to expand the research capability of the Expedition 38 crew members aboard the orbiting laboratory, crew provisions, spare parts and experiment hardware. - Also aboard the flight are 23 student experiments that will involve more than 10,000 students on the ground. These experiments will involve life sciences topics ranging from amoeba reproduction to calcium in the bones to salamanders.

The secondary payloads (34 CubeSats, commercial payloads of Orbital Sciences) on the Cygnus CRS-1 mission were:

- ArduSat-2, a 2U CubeSat (2 kg), a crowd-funded project of NanoSatisfi LLC.

- LituanicaSAT-1, a CubeSat of KTU (Kaunas University of Technology), Kaunas, Lithuania.

- LitSat-1, a 1U CubeSat of LSF (Lithuanian Space Federation).

- SkyCube, a 1U CubeSat, a crowd-funded project of Southern Stars Group LLC, San Francisco, CA, USA.

- UAPSat-1, a 1U CubeSat of UAP (Universidad Alas Peruanas), built by INRAS-PUCP (Institute for Radio Astronomy of the Pontificia Universidad Católica del Perú), Lima, Peru.

- Flock-1 fleet of 28 satellites (all 3U CubeSats) of Planet Lays Inc. of San Francisco, CA. Flock 1 is designed to deliver frequent, low-cost and high-resolution imagery of the planet that could help monitor deforestation, track natural disasters and benefit humanity in a number of other ways. All Flock-1 nanosatellites provide imagery with a resolution of 3-5 m.

All CubeSats will be using the NanoRacks deployer system on the ISS. They are deployed using the J-SSOD ( JEM Small Satellite Orbital Deployer).

The Cygnus CRS Orb-1 spacecraft arrived at the ISS on Jan. 12, 2014 when astronauts captured the Cygnus supply craft using a robotic arm. The arrival capped the first successful contracted cargo delivery by Orbital Sciences Corp. of Dulles, VA, for NASA. 75)

Cygnus will remain attached to Harmony until a planned unberthing in February sends the spacecraft toward a destructive reentry into Earth's atmosphere.

• The Salt Lake City metropolitan area (Figure 72) is located along the western front of the Wasatch Range in northern Utah. The city is known as "the crossroads of the West," as the headquarters of the Church of Jesus Christ of Latter-day Saints (known informally as the Mormon Church), and as the state capital of Utah. Salt Lake City was founded in 1847 by Brigham Young, together with other followers of the Mormon faith. The city and surrounding urban areas is home to more than 2 million people, approximately 80 percent of the population of the state. 76)

Viewed at night from the vantage point of the International Space Station, the regular north-south and east-west layout of street grids typical of western U.S. cities is clearly visible. Both the color of the city lights and their density provide clues to the character of the urban fabric. Yellow-gold lights generally indicate major roadways, such as Interstate Highway 15, which passes through the center of the metropolitan area. Bright white clusters are associated with city centers, and commercial and industrial areas. Residential and suburban areas are recognizable as diffuse and relatively dim lighting.

This incredibly sharp image shows the grid-like streets of Valencia surrounding the older, less-structured, center. The ‘claw' extending to the top is the port of Valencia that serves as a breakwater as well as a platform to offload ships. 77)

Lights of a ship that is either leaving or arriving at the port can be seen. The blackness to the top left of this image is the Mediterranean Sea where no streetlights exist. Other areas of blackness are parks and countryside, places where humans have not settled and installed artificial lights. The bright blue lights to the bottom of the image are from Valencia's airport and industrial sites.

• The Long Island Sound (USA) is well outlined by city and roadway lights in this nighttime photograph taken from the International Space Station. The manmade traceries of light are accompanied by a natural phenomenon: Fog is visible stretching along several river valleys. - Long Island Sound is an estuary along the upper East Coast of the United States. The area is bound by Long Island (New York state) to the south, the coastline of Connecticut to the north and the southeasternmost coastline of New York to the west. 78)

• Sept. 05, 2013 (UTC): One of the Expedition 36 crew members aboard the International Space Station took this picture (Figure 76) of the Japanese HTV-4 (H-II Transfer Vehicle-4) unmanned cargo spacecraft, backdropped against a land mass on Earth, following its unberthing but just prior to its release from the orbital outpost's Canadarm2. HTV-4, after backing away from the flying complex, headed for re-entry into Earth's atmosphere, burning upon re-entry. HTV-4 was launched by Japan's Aerospace Exploration Agency (JAXA) on Aug. 4, 2013 in order to bring up supplies for the astronauts and cosmonauts onboard the station. 79)

• The photograph of Figure 77 from the International Space Station highlights a late-summer "whiting event" visible across much of Lake Ontario (one of North America's Great Lakes). Such events commonly occur in late summer and are caused by changes in water temperature, which allows fine particles of calcium carbonate to form in the water column. Increased photosynthesis by phytoplankton and other microscopic marine life can also reduce the amount of carbon dioxide in the water column, changing the acidity and allowing calcium carbonate to form. These particles of calcium carbonate cause the characteristic lightening ("whiting") of the water color observed. 81)

• June 2013: From the vantage point of the International Space Station, astronauts frequently observe atmospheric and surface phenomena in ways that are impossible to view from the ground. Two such phenomena—gravity waves and sunglint—are illustrated in this photograph (Figure 80) of northeastern Lake Superior. 84)


Figure 80: Gravity Waves and Sunglint Accent Lake Superior; the image was acquired on June 24, 2013 with a Nikon D3S digital camera (image credit: NASA)

Legend to Figure 80: At the top of the image, the Canadian Shield of southern Ontario is covered by an extensive forest canopy typical of early summer. Offshore and to the west and southwest of Pukaskwa National Park, several distinct sets of parallel cloud bands are visible. Gravity waves are produced when moisture-laden air encounters imbalances in air density, such as might be expected when cool air flows over warmer air. This can cause the flowing air to oscillate up and down as it moves, causing clouds to condense as the air rises and cools and to evaporate away as the air sinks and warms. This produces parallel bands of clouds oriented perpendicular to the wind direction. The orientation of the cloud bands in this image, parallel to the coastlines, suggests that air flowing off of the land surfaces to the north is interacting with moist, stable air over the lake surface, creating gravity waves.

The second phenomenon—sunglint—affects the water surface around and to the northeast of Isle Royale. Sunglint is caused by light reflection off a water surface; some of the reflected light travels directly back towards the observer, resulting in a bright mirror-like appearance over large expanses of water. Water currents and changes in surface tension—typically caused by presence of oils or surfactants—alter the reflective properties of the water and can be highlighted by sunglint. For example, surface water currents are visible to the east of Isle Royale that are oriented similarly to the gravity waves, suggesting that they too are the product of winds moving off of the land surface.


• Astronauts aboard the ISS photographed these striking views of Pavlof Volcano in Alaska on May 18, 2013 (Figure 85). The oblique perspective from the ISS reveals the three dimensional structure of the ash plume, which is often obscured by the top-down view of most remote sensing satellites. 85)

Located in the Aleutian Arc about 1000 km southwest of Anchorage, Pavlof began erupting on May 13, 2013. The volcano jetted lava into the air and spewed an ash cloud 6,000 m high. When the photograph (ISS036-E-2105) was taken, the space station was about 770 km south-southeast of the volcano (49.1° North latitude, 157.4° West longitude). The volcanic plume extended southeastward over the North Pacific Ocean.

• January 1, 2013: A Sleeping Giant (Figure 83), the Beauty and Threat of Vesuvius. A nearly vertical look onto Italy's Mount Vesuvius, the volcano that blew its top in 79 AD in the most famous volcanic eruption in recorded history. About 16,000 people lost their lives that day due to pyroclastic flow—searing hot ash blasting outward from the stratovolcano's maw. 87)

The volcano has erupted many times since then, including in the 20th century. Mount Vesuvius is still active. By taking another look at Figure 83 and the volcano's surrounding settlements, and the city of Naples just a few km away — it is mind blowing! More than half a million people live in the volcano's red zone—where destruction from a big eruption would be swift and brutal.

The Nightpod camera-stand tracks the movement of Earth passing under the Station at 28,800 km/h, keeping any target fixed in the middle of the viewfinder. Standard cameras fixed to Nightpod can use longer exposure times so that astronauts can take sharper pictures of cities at night. The Nightpod is described in a separate file on the eoPortal under ISS: Nightpod. 88)

• On July 8, 2011, STS-135 ISS ULF7 flight of Atlantis was launched, representing the final Shuttle mission. The primary objective is to deliver cargo and supplies to the ISS; among them the Raffaello MPLM (Multi-Purpose Logistics Module). STS-135 is a late—and final—addition to the shuttle manifest. It is carrying out a key mission to help support the continued operations of the ISS and testing technology that can support satellite servicing. 89)

Legend to Figure 86: This picture and others taken by Paolo Nespoli with the Nikon D3X camera, were the first taken of a shuttle docked to the International Space Station from the perspective of a Russian Soyuz spacecraft. Onboard the Soyuz were Russian cosmonaut and Expedition 27 commander Dmitry Kondratyev; Nespoli, a European Space Agency astronaut; and NASA astronaut Cady Coleman. Coleman and Nespoli were both flight engineers. The three landed in Kazakhstan later that day, completing 159 days in space.

• The arrival of the WORF (Window Observational Research Facility) has allowed astronauts to permanently remove a protective, non-optical "scratch pane" on the window, which had often blurred images. The WORF also provides a highly stable mounting platform to hold cameras and sensors steady, while offering power, command, data, and cooling connections. With the WORF, the high-quality optics of the nadir viewing window—looking "straight down" towards the Earth—are now fully utilized for the first time since Destiny was launched in 2001. 91)

The WORF was delivered to the ISS in April 2010 on the STS-131 mission of Space Shuttle Discovery. It was installed and prepped on the Destiny Laboratory during 2010, and includes the highest quality optics ever flown on a human-occupied spacecraft.

• On February 7, 2008, the Space Shuttle flight STS-122 was launched to deliver ESA's Columbus Laboratory to the ISS, Three EVAs (Extra Vehicular Activities) were needed to install the Columbus Laboratory at the US Node 2 of ISS, called Harmony. The 7 m long laboratory consists of a pressurized cylindrical hull 4.5 m in diameter,closed with welded end cones, providing a volume of 75 m3. 92) 93)

• May 31, 2006: Located just north of the equator (3.85° North, 154.9° East), this classically shaped atoll is part of the Caroline Islands, which stretch northeast of Papua New Guinea in the western Pacific (the islands are roughly north of Guadalcanal, and southeast of the Guam and Truk Islands). Nukuoro Atoll is one of 607 islands that make up the Federated States of Micronesia, a United Nations Trust Territory under U.S. administration. 94)

- An atoll is a type of low, coral island found in tropical oceans and consisting of a coral-algal reef surrounding a central depression. The depression may be part of the emergent island, but more typically is a part of the sea (that is, a lagoon).

- About 900 people live on Nukuoro, whose lagoon is 6 km in diameter. Fishing, animal husbandry and agriculture (taro and copra) are the main occupations. Nukuoro is remote and has no airstrip; a passenger boat calls irregularly only once a month. The tiny population speaks its own unique language.

• On Nov. 2, 2000, the Expedition 1 crew — Commander William M. (Bill) Shepherd of NASA and Flight Engineer Sergei Krikalev and Soyuz Commander Yuri Gidzenko of Roscosmos — arrived at the International Space Station, marking the start of an uninterrupted human presence on the orbiting laboratory. Their Soyuz capsule made contact with the aft docking port of the station's Zvezda Service Module at 3:21 A.M. CST (Central Standard Time) while the two spacecraft were flying over the central portion of Kazakhstan. A little over one hour later at 4:23 A.M., the hatch leading into the Zvezda's living quarters was opened, signifying the start of human occupancy of the international complex. Gidzenko and Krikalev floated into Zvezda first, at the request of the commander. Once inside the station, the crew members continued the work begun by space shuttle crews and ground controllers to bring the station to life. 95)


Figure 90: This Dec. 2, 2000, photograph shows the configuration of the space station at the start of Expedition 1 including the Zarya Control Module, Unity Node, Zvezda Service Module and Z1-Truss. It was taken by STS-97 crewmembers aboard shuttle Endeavour during approach to dock with the station on a mission to deliver and connect the first set of U.S.-provided solar arrays, prepare a docking port for arrival of the U.S. Laboratory Destiny and perform additional station assembly tasks. The Expedition 1 crew spent four months living and working on the station and returned to Earth aboard shuttle Discovery on March 21, 2001 (image credit: NASA)


• On Dec. 4, 1998, NASA's space shuttle Endeavour launched Unity, the first U.S. module of the complex, during the STS-88 mission. The seven-day mission was highlighted by the mating of the U.S.-built Unity node to the Functional Cargo Block (Zarya module) already in orbit, and three spacewalks to connect power and data transmission cables between the Node and the FGB. Other payloads on the STS-88 mission included the ICBC (IMAX Cargo Bay Camera), the Argentine Scientific Applications Satellite-S (SAC-A), the MightySat 1 Hitchhiker payload, the Space Experiment Module (SEM-07) and Getaway Special G-093 sponsored by the University of Michigan. 96) 97)

- The STS-88 launch begins the largest cooperative space construction project in history. Endeavour is scheduled to rendezvous with the U.S.-funded and Russian-built Zarya control module on Dec. 6. Zarya, which in Russian means sunrise, lifted off from the Baikonur Cosmodrome in Kazakhstan, on Nov. 20.

- After reaching orbit, Commander Bob Cabana, Pilot Rick Sturckow and Mission Specialists Nancy Currie, Jerry Ross, Jim Newman and Sergei Krikalev began preparing for the first of several engine firings that will bring Endeavour within Canadarm's reach of Zarya. Along the way, the crew will use the same 15 m long Canadarm Dec. 5 to remove the Unity module from the payload bay and connect it to the shuttle's docking hatch. Crew members will use the robot arm to grapple Zarya on Dec. 6 and dock it to one of Unity's two Pressurized Mating Adapters.

- Newman and Ross are scheduled to conduct the first of the mission's three space walks Dec. 7. The space walks will connect electrical and communications lines between Unity and Zarya, and prepare Unity's systems for activation.

- After Endeavour undocks from the International Space Station on Dec. 13, the crew will deploy two small technology demonstration satellites called MightySat and the Argentine SAC-A (Satelite de Aplicaciones/Scientifico-A).

• November 20, 1998: The Zarya Module, also known by the Russian acronym FGB (Functional Cargo Block), was the first component launched for the International Space Station. This module was designed to provide the station's initial propulsion and power. The 19,323 kg pressurized module was launched on a Russian Proton rocket in November 1998. 98) 99)

- The U.S.-funded and Russian-built Zarya, which means "Sunrise" when translated into English, is a U.S. component of the station, although it was built and launched by Russia. The module was built by the Khrunichev State Research and Production Space Center, which is also known as KhSC, in Moscow under a subcontract to The Boeing Company for NASA. Only weeks after Zarya reached orbit, the Space Shuttle Endeavour made a rendezvous and attached a U.S.-built connecting module called Node 1, or Unity. The Zarya Module provided orientation control, communications and electrical power attached to the passive Unity while the station awaited launch of the third component, a Russian-provided crew living quarters and early station core known as the Zvezda Service Module. The Service Module enhanced or replaced many functions of Zarya. The Zarya module is now used primarily for its storage capacity and external fuel tanks.

- The Zarya Module is 12.33 m long and 4.12 m wide at its widest point. Its solar arrays and six nickel-cadmium batteries can provide an average of 3 kW of electrical power. Its side docking ports accommodate Russian Soyuz spacecraft and unpiloted Progress resupply spacecraft. Each of the two solar arrays is 10.67 m long and 3.35 m wide. The module's 16 fuel tanks combined can hold more than six tons of propellant. The attitude control system for the module includes 24 large steering jets and 12 small steering jets. Two large engines were available for reboosting the spacecraft and making major orbital changes before Zvezda arrived.

- Construction of the Zarya Module began at KhSC in December 1994. It was shipped to the Baikonur Cosmodrome, Kazakhstan, launch site to begin launch preparations in January 1998. The three-stage Proton rocket launched the module into a 220.4 x 339.6 km. During launch, the module's systems were in an idle mode to conserve battery power. After reaching the initial elliptical orbit and separating from the Proton's third stage, a set of preprogrammed commands automatically activated the module's systems and deployed the solar arrays and communications antennas. Using the Russian Kurs system, the Zarya performed an automated and remotely piloted rendezvous and docking with the Service Module in orbit. After several days of operational tests, the module was commanded to fire its engines and circularize its orbit at an altitude of about 386 km, the orbit at which Endeavour made rendezvous and captured the spacecraft to attach it to the U.S.-built Unity Node.
