This science paper model is the Hayabusa 2, the follow-on mission to the Hayabusa mission as proposed by the Japanese space agency, JAXA (Japan Aerospace Exploration Agency). The goal for Hayabusa 2 is to build upon the legacy of the original mission, by strengthening the shown weak points.
The target is asteroid (162173) 1999 JU3 with a proposed launch in November–December 2014. Hayabusa 2 would then be 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 next mission will feature more durable ion engines, upgraded guidance and navigation technology, and new antennas and attitude control systems. 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.
