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.

and don't forget Main Belt Comets, or damocloids. not to mention the probable presence of water ice on the surface of Ceres, or the discovery of refractory materials in the samples from comet Wild 2.
it is becoming more and more clear that the difference between comets and asteroids is not as clear cut as it seemed up to 20 years ago, and that there is actually a sort of continuum between the two |

To me, metals are easier to understand as they are elements. Since our Sun is the only fusing body yet to explode our solar system's metal asteroids (raw materials, at least) must have come from inter galactic space (presumably as gaseous metals). However, water is not an element and that makes me feel uneasy. Can water be produced locally inside our solar system? Or, did water also come from outside? Do we know at all? P |
