Japanese hayabusa 2 space mission المستكشف الفضائي الياباني الجديد هاياب...

Hayabusa 2 is an asteroid sample return mission operated by the Japanese space agency, JAXA. It follows on from Hayabusa and addresses weak points learned from that mission.[2] . The target is asteroid (162173) 1999 JU3. Hayabusa 2 is expected to arrive at the target in July 2018, survey the asteroid for a year and a half, depart in December 2019, and return to Earth in December 2020.[5]



The spacecraft features ion engines, upgraded guidance and navigation technology, antennas and attitude control systems.[7] Operations at the asteroid will be similar[clarification needed] to those of the previous Hayabusa, but with an explosive device to dig the asteroid surface for fresh sample material.[5]
