VCLS-1 (Venture Class Launch Services-1) Mission of Rocket Lab for NASA
Rocket Lab (of Huntington Beach, CA, USA, and Auckland, New Zealand) is preparing for its first operational flight of their Electron rocket from its launch site on the Mahia Peninsula in New Zealand. The mission will capitalize on the highly successful test flight of Electron in January, which saw the unexpected and previously unannounced launch of the Humanity Star payload as well as the planned debut of Electron's Curie kick-stage (third stage). 1)
Electron – from testing to operational flights: Rocket Lab's successful flight of the "Still Testing" Electron rocket from New Zealand in January has paved the way for the company to begin operational flights of their revolutionary smallsat launcher. "Still Testing" was the second Electron to fly following the inaugural launch of the vehicle on 25 May 2017. That maiden launch ended in a range safety-issued destruct command to the rocket after a ground systems issue prevented communication with the rocket, named "It's a Test".
Because the cause of the first flight's termination was not in anyway due to a malfunction on the rocket, the actual changes and differences between the first and second flights of Electron were quite insignificant.
"The difference between flight one and flight two [was] almost nothing," said Peter Beck , Rocket Lab's founder and CEO (Chief Executive Officer). "There were software upgrades, and clearly we fixed issues with the ground systems for flight termination, but I there wasn't a huge delta between the vehicles."
And the same will generally hold true between flights two and three, the final test flight and the first operational flight, with Peter Beck noting that some modifications will be made but that Rocket Lab is "pretty much .... locked in full production" of Electron at this point.
To this end, the second test flight, Still Testing, provided the team with additional data for review and validation while also launching Electron's first payloads into Earth orbit. But before those payloads made it to their destinations, Rocket Lab's launch team had to overcome a series of technical, weather, and range related safety issues that ultimately delayed Still Testing's launch six times between December 2017 and January 2018.
When "Still Testing" launched on 21 January 2018 (UTC), the mission was a resounding success – with good weather, a perfectly functioning rocket that placed its payloads into Earth orbit, and the debut of Electron's optional Curie kick-stage (third stage). The need for the kick-stage stemmed from a decision made by Rocket Lab for the second stage engine to only perform a single burn instead of being restartable.
Operational flights to start soon: With its tests flights behind them, Rocket Lab is now preparing for the first operational flight of the Electron, which is expected to fly in the near future. "Our next flight is going to be a full commercial flight, and we're manifesting that as quickly as we can," said Peter Beck. "Obviously we didn't manifest that before because it equally well could have been a test flight."

In April 2018, Rocket Lab and NASA have carried out the integration of the CubeSat payloads scheduled to launch on the Electron rocket of Rocket Lab in the first half of 2018 for NASA's first ever VCLS (Venture Class Launch Services) mission. The flight will constitute the smallest class of dedicated launch services used by NASA and marks a significant milestone for Rocket Lab in providing such access to space for a NASA-sponsored mission of small satellites. 3) 4)
The launch is manifested with innovative research and development payloads from NASA and educational institutions that will conduct a wide variety of new, on-orbit science. Applications of the CubeSats booked on the mission include research such as measuring radiation in the Van Allen belts to understand their impact on spacecraft, through to monitoring space weather.
"We're incredibly excited to be launching NASA's first Venture Class mission," says Rocket Lab founder and CEO Peter Beck. "The VCLS contract by NASA's Launch Services Program is very forward-thinking and a direct response to the small satellite industry's changing needs for rapid and repeatable access to orbit. The oversight NASA has provided to us as part of this contract has been tremendously valuable for us."
Big ideas used to require big rockets, but thanks to the miniaturization of technology, the small satellites of today can conduct innovative science that helps us better understand the Earth and our universe. Before Rocket Lab's Electron vehicle, launch opportunities for small satellites were mostly limited to rideshare-type arrangements on large launch vehicles, flying only when space was available on NASA and other launches. This can be impractical for some small satellite payloads, as they are at the mercy of the primary payload's schedule and desired orbit. Rocket Lab's Electron is the only private, small launch vehicle currently flying to orbit and offering the dedicated flights tailored to these small payloads.
"Venture Class launches are about freeing small satellite payloads from the barriers they currently face in trying to access space on larger launch platforms as secondary payloads. It's fantastic to see NASA enabling this change and embracing private small launch vehicles like Electron," adds Mr. Beck.
Ten CubeSats manifested on the mission are receiving their access to space through a NASA initiative called CSLI (CubeSat Launch Initiative) and are part of ELaNa-19 (Educational Launch of Nanosatellites-19) . The program recognizes that CubeSats are playing an increasingly larger role in exploration, technology demonstration, scientific research and educational investigations. These miniature satellites provide a low-cost platform for both research and commercial applications, including planetary space exploration; Earth observation; Earth and space science; and developing precursor science instruments like laser communications, satellite-to-satellite communications and autonomous movement capabilities.
The recent payload integration process, which took place at Rocket Lab USA's facility in Huntington Beach, California, involves conducting final spacecraft checks and preparations before the CubeSats are loaded into dispensers that protect the payloads during launch, then deploy them from the Electron vehicle once in low Earth orbit. The integrated payloads will be shipped to New Zealand for mating onto the Electron launch vehicle in coming weeks, before a launch from Rocket Lab's private orbital launch facility, Launch Complex 1.

A host of CubeSats, or small satellites, are undergoing the final stages of processing at Rocket Lab USA's facility in Huntington Beach, California, for NASA's first mission dedicated solely to spacecraft of their size. This will be the first launch under the agency's new Venture Class Launch Services. Scientists, including those from NASA and various universities, began arriving at the facility in early April with spacecraft small enough to be a carry-on to be prepared for launch. 6)

A team from NASA's Goddard Spaceflight Center in Greenbelt, Maryland, completed final checkouts of a CubeSat called the Compact Radiation Belt Explorer (CeREs), before placing the satellite into a dispenser to hold the spacecraft during launch inside the payload fairing. Among its missions, the satellite will examine the radiation belt and how electrons are energized and lost, particularly during events called microbursts — when sudden swarms of electrons stream into the atmosphere.
This facility is the final stop for designers and builders of the CubeSats, but the journey will continue for the spacecraft. Rocket Lab will soon ship the satellites to New Zealand for launch aboard the company's Electron orbital rocket on the Mahia Peninsula this summer.
The CubeSats will be flown on an Educational Launch of Nanosatellites (ELaNa) mission to space through NASA's CubeSat Launch Initiative. CeREs is one of the 10 ELaNa CubeSats scheduled to be a part of this mission.
