I can't wait to see the color image. And I am now eagerly anticipating the landing. Until now, I have tried not to get my hopes to high about this mission. But it looks like they are pulling it off!

Congratulations to the JAXA team on this achievement so far.
 The really exciting stuff is still to come of course but there is no doubt about the dedication and patience that the team took to get here. |

Much like the colour image from DI, or the occasional colour image from NEAR...it showed very little colour variation. It's only when stretched to hell and back that you get something like the freaky colours Galileo showed us of the asteroids it visited en-route.

Perhaps I am speaking too soon, but the planetoid does not seem to have very many impact craters, at least large ones.
-------------------- "After having some business dealings with men, I am occasionally chagrined,
and feel as if I had done some wrong, and it is hard to forget the ugly circumstance. I see that such intercourse long continued would make one thoroughly prosaic, hard, and coarse. But the longest intercourse with Nature, though in her rudest moods, does not thus harden and make coarse. A hard, sensible man whom we liken to a rock is indeed much harder than a rock. From hard, coarse, insensible men with whom I have no sympathy, I go to commune with the rocks, whose hearts are comparatively soft." - Henry David Thoreau, November 15, 1853 |

I see lots of small ones on the latest image, but any large ones would have smashed what is likely to be a fragile body to pieces.

Woo-hoo! I'm on vacation in the UK, starved for information on anything other than celebrity weddings, and finally I find a cyber cafe... yes, I know, it's a trifle obsessive of me... - so today I first saw these new images of Itokawa. Fabulous! This should be a really interesting mission.
Eros had 'ponds' of smooth material filling deprssions. Maybe the large central smooth area is such a pond here. Electrostatic processes were thought to be responsible, I think. Phil -------------------- ... because the Solar System ain't gonna map itself.

Doug  I agree with what others have posted, it looks like about 2 large and 1 small body attached together in a peanut shape, with dust infill between the bodies. Hopefully they'll try sample return from both types of "surfaces". I'll bet those "smooth" areas are extremely fluffy dust...Hopefully Minvera will work without just falling into a dust-drift! -------------------- Space Enthusiast Richard Hendricks

Toma: Interesting images - the spiky horizon is quite odd, though it may be an artefact of the processing and the direct down-sun illumination. JAXA have really done well this time! Bob Shaw -------------------- Remember: Time Flies like the wind - but Fruit Flies like bananas!

Some cool new graphs up. No color image yet. I think that if this asteroid is as gray as others we have explored, it may be harder than they thought to make a color image look convincing, particularly if there are color flecks due to noise. -------------------- |
