The Hayabusa and Hayabusa2 missions returned samples from asteroids before NASA's OSIRIS-REx sample-return mission.
ChibaTech's lander and payload designs build on flight heritage from ChibaTech student CubeSat projects and Japan's Hayabusa missions.
Hayabusa launched in 2003 targeted asteroid 25143 Itokawa as a sample return mission to return asteroid material for detailed analysis.
Hayabusa2 is the follow-on mission to Hayabusa, which launched in 2003 and returned the first asteroid samples from Itokawa to Earth in 2010.
