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.
It was mentioned here: http://www.jspec.jaxa.jp/080110Final_IPEWG-ProgramBook.pdf |

Reading all these texts convinces me that these small pebbles brought to the Earth by Hayabusa2 are a perfect reflection of the vast majority of rocks, boulders and stones on the surface of Ryugu. They look the same, have the same texture, structure, color, chemical composition, cracks, etc. etc. So, these small grains are for researchers the same as large stones - if, for example, they were brought by astronauts landing on Ryugu!
In fact, it looks as if Ryugu has an almost fractal structure! [A similar phenomenon was observed by the Rosetta probe and the Philae lander on the nucleus of comet Churyumov-Gerasimenko. It might just be a feature typical of primitive (little modified) Worlds in the Solar System (and maybe not only here!).] However, I am a bit disappointed with the complete absence of chondrules and CAIs (calcium-aluminum-rich inclusions) in the Ryugu material, and common in chondrites ![]() I was hoping to finally see the natural "chondrite rock" - the mythical „oldest and most primeval rock” and „source of chondrite meteorites”... ![]() |
