Hayabusa 2
Encyclopedia
Hayabusa 2 is the follow-on mission to the Hayabusa
mission as proposed by the Japanese space agency, JAXA. The goal for Hayabusa 2 is to build upon the legacy of the original mission, by strengthening the shown weak points. As of January 2011, the target is asteroid (162173) 1999 JU3
with a proposed launch in July 2014, with backup launch opportunities in December 2014, June and December 2015. Hayabusa 2 would then be expected to arrive to the target in 2018, survey the asteroid for a year and a half, depart in December 2019, and return to the earth in December 2020. 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.
In July 2009, at the 27th ISTS (International Symposium on Space Technology and Science) conference in Japan, presentations were given that elaborated upon the most recent Hayabusa 2 mission concept. Makoto Yoshikawa of JAXA presented a paper entitled "Hayabusa Follow-on Asteroid Sample Return Missions." Dr. Yoshikawa stated that JAXA has a new proposal for Hayabusa 2, namely that the mission have two spacecraft with one specifically being an impactor.
In August 2010, JAXA got the go-ahead from the Japanese government to begin development of Hayabusa 2. The estimated cost of the project is 16.4 billion yen.

Funding problems and international cooperation
Hayabusa 2 was agreed by the SAC during 2006 and was announced in a new year interview with JAXA president Keji Tachikawa.In July 2009, at the 27th ISTS (International Symposium on Space Technology and Science) conference in Japan, presentations were given that elaborated upon the most recent Hayabusa 2 mission concept.
