SkyFire is a planned nanosatellite spacecraft that will fly by the Moon and collect surface spectroscopy and thermography. It is scheduled to fly on the Space Launch System, Exploration Mission 1 (EM-1) scheduled to launch in 2020.


Its purpose is that of a Geosynchronous Earth Orbit (GEO) technology demonstration using a low-cost 6U CubeSat spacecraft. SkyFire will perform a lunar flyby, collecting spectroscopy and thermography for surface characterization, remote sensing, and site selection.[2] The spacecraft includes two deployable solar arrays and will have a total mass of about 14 kg (31 lb).

SkyFire was selected in April 2015 by NASA's NextSTEP program (Next Space Technologies for Exploration Partnerships) and awarded a contract to Lockheed Martin Space systems worth $1.4 million for further development.[3][4][5]


SkyFire will fly along other 12 CubeSats as a secondary payload mission on the first flight of the Space Launch System, Exploration Mission 1 (EM-1) scheduled to launch in 2020.[1]


SkyFire will also demonstrate a low thrust electric propulsion technology called electrospray propulsion to lower the spacecraft's orbit for additional science and technology mission objectives.[6]
