Near-Earth Asteroid Scout : ウィキペディア英語版 | 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). The NEA Scout will be one of 11 CubeSats to be carried with the Orion EM1 mission into a heliocentric orbit in cis-lunar space on the maiden flight of the Space Launch System (SLS) scheduled to launch in 2018. A variety of potential targets would be identified based upon launch date, time of flight, and rendezvous velocity.NASA's Marshall Space Flight Center (MSFC) and Jet Propulsion Laboratory (JPL) are jointly developing this mission with support from NASA's Goddard Space Flight Center, Lyndon_B._Johnson_Space_Center, Langley Research Center, and NASA Headquarters.==Goal==The goal is to develop a capability that would close knowledge gaps at a near-Earth asteroid (NEA), in the 1-100 m range, identified for human exploration. NEAs in the 1-100 m range are poorly characterized due to the challenges that come with detecting, observing, and tracking these for extended periods of time. It has been thought that objects in the 1-100 m size range are fragments of bigger objects. However, it has also been suggested that these objects could actually be rubble-piles.The mission researchers argue that "characterization of NEAs that are larger than 20 m in diameter is also of great relevance to inform mitigation strategies for planetary defense." Also, the NEA Scout target characterization would help inform the Asteroid Redirect Mission.
