Hayabusa2

JAXA's follow-up to Hayabusa — a far more capable mission to the carbonaceous asteroid Ryugu. It deployed rovers and a lander, fired a projectile to make an artificial crater and sample subsurface material, and returned 5.4 grams of pristine, water- and organic-bearing rock. The spacecraft is now on an extended mission to a small fast-rotating asteroid.

Targets & sample

Target bodies:162173 Ryugu
Returned sample:Ryugu Sample (Hayabusa2)

Mission & science

Goals
Return a sample of a carbonaceous (C-type) asteroid, including subsurface material exposed by an impactor.
Engineering milestones
Deployed the MASCOT lander and MINERVA-II rovers; the Small Carry-on Impactor made an artificial crater (2019).
Science discoveries
Ryugu is a carbon-rich rubble pile; its samples contain water-bearing minerals and amino acids.
Sample return
5.4 g of surface and subsurface material, recovered at Woomera, Australia, in December 2020.
Outcome
Complete success; extended to asteroid 1998 KY26.
