JAXA wants to continue with Hayabusa 2. However there is/was a huge fight about the budget. Main problem was the budget for the launch vehicle. 2 months ago or so there was a report which said, that JAXA had to find another launch vehicle or the project gets cancelled. Now the Italian space agency played saviour and overed the VEGA. So finally we might see another Hayabusa in 2011.

Unless I'm wrong, the target of Hyabusa 2 is an asteroid and not a comet, and a very small asteroid at that, why this talk about ice? If the surface is rock hard, I would expect it it to be because it is rock, but loose material on the suface of asteroids and comets seems to be the rule rather than the exception so far.

1999 JU3 is a carbonaceous C-Type asteroid being thought to contain hydrated minerals and organic material, or by its spectrum at least a certain amount of water.
Itokawa, contrasting that, was a rocky S-Tye asteroid. Each Hayabusa mission (1,2,Mk2) is explicitly aimed towards a different type of minor body. |

I guess one of the things Hayabusa will discover is if there is any water present apart from hydrated minerals, although I don't know how Hyabusa will look for volitile, free water in a sample.Hyabusa 1's active collection system, "the bullet" failed, but there was some material collected passively. I looks like teeth have been added to enhance any passive collection, but hopefully the active system will work on Hyabusa 2. As I see it, the teeth can only help, not hurt in any eventuality. |
