Well,
since first pictures are coming up soon why not make a guess where?
Besides a picture of one of the rovers or other landing..or in some cases crash.. sites. Any one have any favorite spots?
The problem with high resolution pictures is when you look at rocks you just see smaller rocks so they can look the same..sort of like a nice fractal...
Nice to have an image with something that is recognizable.
I'm hoping for months end..I prefer tomorrow but I can wait til the end of September..but hopefully not October...
anyone elxe?
cheers

I'm afraid all my favorite targets are landing and crash sites.

Well, if you press me, I'll say It'd be interesting trying to spot the most geologically young lava flow, and try to use small crater counts to date it. I'm guessing there are several scattered sites that could be candidates for the most recent activity.

I would have thought that the pre-conjunction imaging would be of basically, whatever they can grab, much as with the pre aerobraking imaging. I don't think there's the time to schedule sequence and command something more specific than that.

Oops... the mention of landing site targets got me wandering off. You're right. Well, one target that would present itself every orbit would be the north polar cap. A relatively blank, featureless part of it might serve for some kinds of camera calibrations. The border areas would have a lot of detail and contrasts. I'd be willing to bet that polar pictures will be in the mix of the first new pictures to come in since before aerobraking.

I think you are right.. what ever is there, lets take a picture. Just hope the pictures are released as discussed in other thread and not held for months on end like Smart-1 or Mars Express.. I think we have been spoiled by MER.
I really doubt they will target specific sites but lets hope for some "interesting" places they can pass over sooner rather than later.. I'm going to be thrilled with anything they send back actually... but I would prefer victoria myself smile.gif
With high resolution I'm assuming a smaller path along the ground, so that much longer for significant ground cover.
High resolution of the poles melting would be cool smile.gif

Well - at 1.5m/pixel - MOC is approx 3km across and as much as 10km long.

HiRISE at 33cm/pixel has a maximum of 6.6km across and 13.2km long.

I'm thinking that the area around Victoria Crater would be a high-priority area to get HiRISE images of, as soon as possible. That would allow the MER team to spend their time during conjunction doing some real planning. The MOC images we have are nice, but the HiRISE images of the site will be invaluable for planning the Victoria campaign.

Oh, and some good CRISM work in the area would be extraordinarily helpful, too.

In fact, I'm thinking that the first CRISM work ought to be at the MER sites. We have a lot of ground truth at those sites, which will let them approach the overall CRISM results with valuable information about how their readings correlate with what's actually on the ground.

See the following post. MRO will soon take pictures over Victoria Crater in order to improve the coordination of analysis between MER and MRO teams.

I hate to say this, Rodolfo, but the spaceref.com article gave me the impression that they were planning to start studying Meridiani with MRO in November or December. I'm wondering if the Victoria area might not get a priority for at least a first-look from HiRISE and CRISM *before* the solar conjunction.

I can't speak for the HiRISE team, but I believe there's only one day's worth of off-nadir imaging allocated pre-conjunction, so if they don't hit it then, and they don't go right over it, it's not going to happen.

I don't think it's giving much away to say that the MER-B site is in the CTX target database. smile.gif

And I think you're overstating the incremental value of HiRISE imaging over the MOC CPROTO for traverse planning, but I guess we'll see.

The discussion in that article is more about correlation of orbital and MER observations from mineralogical perspective than from one of a planning process. The emphasis in the pre-conjunction and early science mapping phase will likely be the north polar regions (since this expected to be a time of minimal dust loading) and the potential landing sites for Phoenix. Of course, if the ground-track happens to fall across Victoria region during a nadir-sequence orbit, I suspect people would be happy. The planning process has just begun in earnest with the completion of the burn earlier this week...and so, one will know fairly soon.

But wouldn't you want an off-nadir image of Victoria to combine with a later nadir (or near-nadir) image
to get good stereo to make 3-D planning maps? Getting an off-nadir image should be a lot easier than a nadir image, although I admit you still have to get fairly close to an overhead pass. Sorry if I'm stating the obvious.

Isn't MRO observing from entirely different sun angles than MGS? I'm thinking that perhaps a combination of pictures of Victoria taken early morning and late afternoon might aid in understanding the lay of the land a little better than either picture set alone.

No, MGS is at about 2 PM and MRO is at about 3 PM.

Well, guess that's not a whole lot of help, just an hour difference. Thanks for the info, though. Somehow I'd gotten the impression that MRO had gone for a 9 am orbit.
