There are two more releases in March:

03-16-2007 South Polar Cryptic Terrain in Early Spring

03-27-2007 Defrosting of Russell Crater Dunes

There's also a nice gallery page.

The CRISM website (crism.jhuapl.edu) has a cool new feature called CRISM View that allows anyone to see where CRISM is over Mars in real time and what observations it is going to make next. Some of its features:

MRO Mars Ground Track, showing current postion over Mars
CRISM Information Table, showing current instrument settings
Next Scheduled CRISM Observations, a table covering the next few days
Current CRISM View
and more

CRISM View is updated every Sunday at midnight (probably Eastern time)

To run this, you have to install Java 2 Runtime Environment 1.5 (14.2 MB) and Java 3D 1.4 (2.76MB).
This is for PC/Windows. These are available at the CRISM website.

Well, thanks for that. Congratulations to the team who coded the viewer!

I'm still working this out, but is that real-time data or just displayed running from the spice kernels and related data ?

Alexblackwell, that's a very nice multi spectral map.

Will the colour and multi spectral image strips be displayed in a gallery format like the HiRise images ?

This interface appears to include Web access to CTX images too ohmy.gif

And I've just seen that the Marsoweb landing site site has CTX images as well.

too

For those who don't have access to the Journal of Geophysical Research-Planets, the recent paper in the Special Collection - Mars Reconnaissance Orbiter Mission and Science Investigations by Murchie et al. describing the CRISM instrument is available here (3.1 Mb PDF reprint).

I just did some browsing at The PDS Search Page and found the following maps of CRISM data from Gusev and Meridiani areas. Those of you who feel like diving into multispectral data, might find something worth looking at in the neighborhood of Spirit and Opportunity.

Are the red dots spurious noise in the data, or do they actually indicate some radical difference in surface composition? And if so, what does red really indicate in this context?

I have to say, from the looks of it, they look like noise to me. But I'd enjoy knowing, one way or the other.

I think they're actually the locations of crism observations smile.gif

Each will link (on the proper site) to the observation.

Pics look like laser topo models with the locations of the crism data superimposed.

Doug and Ed are right, these are just catalog maps of the CRISM data with the locations of the CRISM images superimposed on a shaded relief map. I should have been a bit clearer in my brief note. sad.gif

If you look at the PDS Search Page you can zoom in even closer to resolve the pattern of the CRISM investigations. What intrigues me is the extent of coverage in the Gusev Hills and along what looks like the track of Opportunity running down to Victoria crater. None of this has made its way into the public discussion of the CRISM data.

Of course, I'd like to see what some of the geologists on board make of the data itself.

It turns out there are some recently published abstracts of studies of the CRISM data from Meridiani:
Initial Analyses of CRISM Data over Meridiani Planum.

and Gusev:
Initial Results from the MRO CRISM in ... Gusev Crater....
Possible Evidence for Iron Sulfates...at Gusev Crater....

From a quick look, they haven't yet looked in detail at the small scale geochemistry in the vicinity of the rovers that CRISM promises to unravel.
