NASA has awarded ExoTerra Corporation a $2.5M contract to demonstrate a novel solar electric propulsion system for CubeSats that will enable the shoebox-sized spacecraft to triple their available power and produce over 2.5 km/s of propulsion.
Under the "Utilizing Public-Private Partnerships to Advance Tipping Point Technologies" award, ExoTerra will use the mission-enabling capability to fly a CubeSat past an asteroid and become the first privately owned company to fly beyond the Moon.
The mission will both demonstrate the solar electric propulsion technology in space for the first time, and support our partner, Deep Space Industries, in their efforts to locate asteroids suitable for mining.
"We are shrinking the size of interplanetary satellites to enable NASA to perform more science at a substantially lower cost," noted Mike VanWoerkom, Founder of ExoTerra.
"The successful demonstration of the technology will enable NASA to perform future missions to asteroids or other inner solar system destinations at costs orders of magnitude below current missions."
The mission has ramifications for the commercial industry as well. ExoTerra's Halo Hall Effect Thruster is less than half the size of competing systems and enables CubeSats to perform long-term orbit control for the first time.
When combined with the high-power solar array, it enables CubeSats to perform reliable commercial operations with more capable sensor packages.
ExoTerra is partnered with Deep Space Industries and Advanced Solutions Inc. on the project. They are scheduled to launch in late 2019.

During an almost two-week search, NASA's OSIRIS-REx mission team activated the spacecraft's MapCam imager and scanned part of the surrounding space for elusive Earth-Trojan asteroids - objects that scientists believe may exist in one of the stable regions that co-orbits the sun with Earth. Although no Earth-Trojans were discovered, the spacecraft's camera operated flawlessly and demonstrated tha ... read more
