The Near-Earth Asteroid Scout (NEA Scout) is a planned mission by NASA to develop a controllable low-cost CubeSat solar sail spacecraft capable of encountering near-Earth asteroids (NEA).[4][5] The NEA Scout will be one of 13 CubeSats to be carried with the Artemis 1 mission into a heliocentric orbit in cis-lunar space on the maiden flight of the Space Launch System (SLS) planned to launch in 2021.[2] The most likely target for the mission is 1991 VG, but this may change based on launch date or other factors.[6] After deployment in cislunar space, NEA Scout will perform a series of lunar flybys to achieve optimum departure trajectory before beginning its two-year-long cruise.
