They re-imaged Eagle Crater and spotted boot prints in the Oppy tracks.

Anyone seen Squyres lately? laugh.gif

For the reason Mcaplinger gave, I don't expect major scientific findings. I think it's something relatively small; something of interest to us, but probably won't even make an inside page of the broadsheet press. (Did any of them run the HiRISE ""trees"" images? I've been housebound by snow & then pork-cough & haven't seen a paper for 10 days.) I reckon "Big" is misdirection, and means "spatially large" rather than "earthshaking significance". Put it this way, I'm confident it'll fall within the forum guidelines of acceptable topics.

Now, cross my palm with silicon, and old mother Imipak will gaze into the swirling cloud of sediment in this fine bottle conditioned ale. Ah, yes! the fog is lifting....

I predict that the number of posts on this thread before the announcement will be less than the number afterwards. Given my record of predictions, I recommend Doug upgrade the server and bandwidth immediately, ahead of the forthcoming flashmob heading UMSF's way on Wednesday wink.gif

FWIW, I quite enjoy it when a little tease is trailed in the water a few days before the odd routine, but interesting-to-us, announcement or release. A little wild speculation and anticipation, within forum guidelines of course, seems like harmless fun... anagrams apart biggrin.gif

Mike, hopefully not OT, but why is MRO's orbit a bit elliptical instead of circular? Is this to minimize atmospheric drag?

A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

"255 x 320 km, and no, there are no plans to lower it."

How about to raise it late in the mission, to delay possible contamination?

It's required to keep the orbit "frozen" at a sun-synchronous precession rate (this was one of many permutations possible.)

In the mission plan, it was to be raised at the end of 2010 (end of the relay mission) but I haven't heard anything about that recently. If consumables are doing OK I expect that will be delayed as long as possible. They never did raise the orbit of MGS AFAIK.

Also, MRO's breakup analysis showed there were no planetary protection issues if it did crash; there was some sterilization to insure this (e.g., cable bundles.) http://adsabs.harvard.edu/abs/2008AdSpR..42.1108B

Maybe Mars Express photobombed a HiRise image?

The entire January issue of Icarus is dedicated to HiRISE; a total of 20 papers!

http://www.sciencedirect.com/science/journal/00191035

Any guess for which one contains the BIG announcement?

Why are you assuming it's in any of them. No press conference scheduled, this isn't going to be a big discovery.

I think if there is going to be any major announcement (there might not be any, as you said no press conference is schedule), and when they have just 20 papers out, then it is logical to assume there is a link between these two events.

I know what you're saying Siravan, but I think it's pretty safe to say that there's going to be no big 'discovery' announced, because:

* There's no NASA press event scheduled
* It has only been mentioned on Twitter (and here, and on UT, both reporting the original Twitter mention)
* None of the "big" space web sites are worked up about this
* No details have leaked out - ALL the major discovery announcements have been leaked, despite being embargoed.

I think the original Tweet has probably been misinterpreted. Having said that, the HiRISE Twitterer hasn't done anything to correct that misinterpretation. Bit naughty, but got us all talking about HiRISE! wink.gif

All these points suggest it's only big to people like us, which makes MPL more likely than a science story. But as we are people like us, that counts as big.

I guess the actual large number of papers is the big announcement.
