It follows on from Hayabusa and addresses weak points learned from that mission. ==Mission overview== Initially, launch was planned for 30 November 2014 (13:23 local time),〔(JAXA Report on Hayabusa-2, May 21st, 2014 )〕 but was delayed to 3 December 2014 04:22 UTC (4 December 2014 13:22:04 local time). The target is asteroid 162173 Ryugu (formerly designated 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.〔 The spacecraft features ion engines, upgraded guidance and navigation technology, antennas and attitude control systems.〔(Japan's next asteroid probe approved for development )〕 Operations at the asteroid will be similar to those of the previous Hayabusa, but with an explosive device to dig the asteroid surface for fresh sample material.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Hayabusa 2」の詳細全文を読む スポンサード リンク
