Japan Successfully Launches Hayabusa 2 Asteroid Sample Return Mission
Japan successfully launched their Hayabusa-2 sample return mission to asteroid 1999 JU3, and JAXA reports the spacecraft is on course and in excellent shape, with its solar panels deployed. The H-IIA F26 rocket carrying the craft blasted off from the Tanegashima Space Center in southwest Japan at 1:22:04 p.m. local time on Dec 3, 2014 (04:22 UTC) , and about two hours later, the spacecraft separated from the rocket and entered its initial planned trajectory.

“To avoid a repetition of the glitches experienced by the first Hayabusa spacecraft, JAXA made several changes. Hayabusa 2 has an updated ion propulsion engine as well as improved guidance and navigation systems, new antennas and a new altitude control system.
Hayabusa 2 has a mini rover called Minerva 2, and for Hayabusa 2’s sample-collecting activities, a slowly descending impactor will be used, detonating upon contact with the surface instead of the high-speed projectile used by the first Hayabusa.
This video explains the Hayabusa 2 mission and how it differs from the first Hayabusa spacecraft:”
You will have noted that Rosetta/Philae had exactly the same problems as Hayabusa. Both of them landed then bounced. The solution employed by Hayabusa II, that of soft landing followed by detonation upon contact, is almost identical to that of Rosetta/Philae. So, fingers crossed everyone.
