QUOTE (Harder @ Feb 23 2007, 08:07 PM)  I'm sure the Rosetta navigational accuracy is second-to-none if ESA aims at only 250 km distance from Mars at 36000 km/hr, Using the European DDOR ability that I mentioned in my Valencia blog - they're currently within 5km of that target point, which isn't bad  Emilys points about P.A. stuff is very true - which is why Voyager can't really help - but NH can during some of it's pseudo-hibernated cruise phases.

hmmmm... Quoting:"For 24 minutes, it will lose the source of power for its major instruments, leaving it reliant on a brace of tiny batteries which were not designed for the task. In the worst case, the probe may fail to reestablish contact with Earth when it emerges on the other side of the red planet." Could this be compared to the "deep sleep" mode of the Mars Rovers? |

...and, he's off!
Well, done, Doug!

Beautiful!!!
 Just occurred to me how spoiled we are...a Mars flyby this week, a Jupiter flyby next week, two Mars rovers, three working Mars orbiters, a Venus orbiter, and Cassini...what a great time to be a UMSFer!

And that's not even a science product...didn't see that one coming at all.

Really? Odd...you'd think that they'd alert the press corps for nice photo-ops like that.

Well, it will take some time
We have to wait until after the eclipse, then the images to be sent... According to ESA's website we'll have to wait until 13:00...And yes, it's a great time to be UMSFer

If I understand the first post, we should be able to expect images between 2 and 3 am CET (I think), so that makes it between 6 and 7 pm MST...

QUOTE (ustrax @ Feb 22 2007, 04:45 AM) Interesting. Given the results at Cassini that suggest that suggest dust rings are common with small moons, it would be a good idea to check this with Phobos and Deimos. But I don't think the BBC article explains why Rosetta is uniquely positioned to look for dust rings effectively. It has nothing to do really with resolution, but with phase angle. Rosetta will observe Mars at very high phase on its outbound leg, which is great position to look for rings made of very fine dust particles. Remember, it took very high phase observations at Saturn to reveal the Pallene ring and the Janus-Epimetheus ring. -------------------- &@^^!% Jim! I'm a geologist, not a physicist!

I do hope that some of them will be published before 13:00 |

If you're all wondering why Doug hasn't posted anything lately it's because, to our surprise, there appears to be no way for him to get on the Net from ESOC! So we're going to do things the old fashioned way -- he'll be phoning me with an update before long. Stay tuned.
