Hayabusa:
Goals: Japan built Hayabusa to test new technologies, including an ion engine, and to collect the first samples from the surface of an asteroid. It also carried a small 600 gram (1.3 pound) mini-lander named MINERVA, which was designed to hop around the asteroid's surface.
Accomplishments: Hayabusa studied and photographed Itokawa for more than two months. Both Hayabusa and MINERVA experienced complications during landing attempts, Hayabusa landed on the asteroid on 19 Nov. 2005 and attempted to collect samples, but it is not clear if this was successful. A sample capsule is scheduled to return to Earth in 2010. Hayabusa was the first spacecraft to successfully land and take off from the surface of an asteroid. MINERVA probably drifted off into space instead of landing.
