The goal is to develop a capability that would close knowledge gaps at a near-Earth asteroid in the 1–100 m range.[1][9][3] 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.[5]
