Spacecraft "Hayabusa2" is planning to recover particles from the surface of a C-type asteroid, "(162173) Ryugu". Expected sample amount is around 1 g, with three touchdown points on the asteroid. Samples recovered by the spacecraft will be opened for international announcement of opportunities after the return back of the spacecraft to the Earth in 2020. This pages will be replaced to the links to the sample catalog and application forms at that time.
