Hayabusa2 (Japanese: はやぶさ2, "Peregrine falcon 2") is an asteroid sample-return mission operated by the Japanese space agency, JAXA.It follows on from the Hayabusa mission which returned asteroid samples in 2010. November 25, 2005: The Hayabusa spacecraft touches down on the surface of asteroid Itokawa, marking only the second time in history that a spacecraft has descended to the surface of an asteroid. The launch mass is 530 kg, including 50 kg of chemical propellant and 65 kg of xenon gas. The Hayabusa spacecraft has a box-shaped main body 1.5 m along each side and 1.05 m high. On 31 July the X-axis reaction wheel failed. January 2007: The Hayabusa spacecraft departs asteroid Itokawa and begins its return trip to Earth 3 months later. Rendezvous with the asteroid occurred in September 2005 with the spacecraft coming to rest relative to the asteroid at a distance of 20 km at 1:17 UT on 12 September. Hayabusa flew by Earth on 19 May 2004 at an altitude of 3725 km at 6:23 UT.
