Concordia Research Station, which opened in 2005, is a French–Italian research facility that was built 3,233 m above sea level at a location called Dome C on the Antarctic Plateau, Antarctica. It is located 1,100 km inland from the French research station at Dumont D'Urville, 1,100 km inland from Australia's Casey Station and 1,200 km inland from the Italian Zucchelli Station at Terra Nova Bay. Russia's Vostok Station is 560 km away. The Geographic South Pole is 1,670 km away. The facility is also located within Australia's claim on Antarctica, the Australian Antarctic Territory. 1)

The Concordia Research Station, a joint interest between the French IPEV (Polar Institute Paul-Emile Victor) and the Italian PNRA (National Antarctic Research Program), is by all accounts one of the most isolated and inhospitable locations available to humanity, requiring more time to reach than it takes to travel to the International Space Station (ISS). The European Space Agency (ESA) takes advantage of the facility's unique location and conditions, conducting extensive research into the implications of long-term space flight on the human body. Read on as we take a look at the conditions at the station, and the importance of the research being carried out there.

The new all-year facility, Concordia Station, became operational in 2005. The first winterover began with a staff of 13 (eleven French and 2 Italians) in February 2005.

Most of the cargo is moved to Dome C by traverse from DDU (Dumont d'Urville) Station, covering 1,200 km in 7 to 12 days depending on weather conditions. Station personnel and light cargo arrive by air, using Twin Otter aircraft from DDU or Mario Zucchelli Station at 1200 km.

Recent events at Station Concordia

• August 13, 2020: After four months of darkness, the Sun finally rises on 11 August at Concordia research station in Antarctica. The crew are understandably reverent. 2)

- They run experiments in human physiology and biology, atmospheric physics, meteorology and astronomy, among other disciplines, as well as maintain the base – one of only three to run year-round on the Antarctic Peninsula.

- Four months of complete darkness is quite the challenge, one researchers are very interested in studying from a physiological and psychological point of view. From questionnaires to blood and stool samples, the crew are poked and prodded to understand how better to prepare humans for deep space travel.

- Social dynamics are also of interest to researchers during the period of darkness. Stress brought on by lack of sunlight, changing sleep patterns, fatigue and moodiness can affect the group. The crew are especially encouraged to take on group activities and get creative to combat the isolation of the winter.

- The first sunrise is always a remarkable moment, signalling the home stretch of their Antarctic residency. From now on the winter crew will start preparing for summer and the return of scientists that arrive for the warmer months starting in November. The base is cleaned thoroughly, machinery is serviced, tents are erected and heated, and the runway is cleared of snow. Extensive work is required to welcome the new arrivals back to the base at the end of the world.

• August 04, 2020: In a peninsula far, far away, a laser shoots into the sky to study the Antarctic atmosphere at Concordia research station. 3)

- The LIDAR (Light Detection and Ranging) instrument is a remote sensing technique that uses light to study an object.

- A pulsed laser beam is aimed at the target and properties of the resulting scattered light are recorded by sensors. Using these measurements, researchers collect information about the atmosphere, including density, temperature, wind speed, cloud formation and aerosol particles.

- LIDAR and SONAR (Sonic detection and ranging) instruments help monitor the Atmospheric Boundary Layer, the 1 km thick bottom layer of the troposphere where changes on Earth’s surface strongly influence temperature, moisture and wind.

- These changes to Earth’s surface are largely caused by human activity. Increased greenhouse gas emissions are raising temperatures and the release of chlorofluorocarbons is thinning the ozone layer, particularly in the Polar Regions.

- Atmospheric physics and chemistry is one field of research undertaken at Concordia to assess the Antarctic climate and overall climate change.

- Concordia also runs biomedical studies as an analogue for space exploration. Each year ESA sponsors a research doctor to continue studies on the psychological, physiological and social effects of living in an isolated, confined and extreme environment.

• May 18, 2020: The 16th crew at Concordia research Station in Antarctica to spend a full winter at the facility, wave goodbye to the Sun as it descends below the horizon, not to return for four months. 5)

- Concordia research station is one of three stations operating year round for science in the middle of the Antarctic ice sheet. Located at Dome C on the Antarctic peninsula, the station sits 3200 m above sea level.

- If the altitude does not steal your breath, the cold certainly will: temperatures can drop to –80°C in the winter, with a yearly average temperature of –50°C.

- Isolation in a cold, dark environment on Earth makes an ideal stand-in for space to better prepare us for exploration of our Solar System. Researchers come to Concordia to study not only astronomy, meteorology and glaciology but also human physiology and psychology.

- Researchers are interested in how this extreme environment can be a risk to the human body and mind. Data from these studies is preparing humans for life in outer space beyond low Earth orbit.

- ESA-sponsored medical doctor Stijn Thoolen coordinates this year’s biomedical research experiments at Concordia to assess the prolonged effects of isolation on the human body and mind.

- He collects blood, stool and urine samples to track changes in blood volume, immune system and gut bacteria and how they impact our health. Stijn also facilitates stress and coordination tests and follows social dynamics to understand the roles stress plays in making or breaking a group in isolation.

- The coming months will prove the most challenging for the group but potentially also the most rewarding.

• March 22, 2013: Concordia research station in Antarctica is located on a plateau 3200 m above sea level. A place of extremes, temperatures can drop to –80°C in the winter, with a yearly average temperature of –50°C. 6)

- As Concordia lies at the very southern tip of Earth, the Sun does not rise above the horizon in the winter and does not set in the summer. The crew must live without sunlight for four months of the year.

- The altitude and location mean that the air in Concordia is very thin and holds less oxygen. Venturing outside the base requires wearing layers of clothes and limits the time spent outdoors.

- During the harsh winter no outside help can be flown in or reach the base over land – the crew have to solve any problems on their own.

- In addition, Concordia sits in the largest desert in the world. The air is extremely dry, so the crew suffer from continuously chapped lips and irritated eyes.

- No animals can survive in this region – even bacteria find it hard coping with the extreme temperatures. The nearest human beings are stationed some 600 km away at the Russian Vostok base, making Concordia more remote than the International Space Station.

- In the great open landscape covered in darkness, colors, smells and sounds are almost non-existent, adding to the sense of loneliness.

- The isolation and sensory deprivation can wreak havoc on crewmembers’ biological clock, making it hard to get a good night’s sleep.

- Despite all these hardships, up to 16 people spend around a year at a time living in Concordia in the name of science. Far removed from civilization, the white world of Antarctica offers researchers the opportunity to collect data and experiment like no other place on Earth.

- The base is so unlike anything found elsewhere in the world that ESA participates in the Italian-French base to research future missions to other planets, using the base as a model for extraterrestrial planets.

The French–Italian Concordia station’s program of research includes glaciology, human biology and the atmosphere. ESA uses the base to prepare for future long-duration missions beyond Earth. During the winter, Concordia is under almost total darkness, with an average temperature of –51ºC and a record low of –85ºC. It is an ideal place to study the effects on small, multicultural teams isolated for long periods in an extreme, hostile environment.

Auroras occur frequently over both the North and South polar regions, but are often difficult to see from populated areas. During periods of increased solar activity, the lights sometimes extend to populated latitudes.
