Astonishing features. So many things. So few rovers.

Unfortunately, that is all too true. But I think we will get to see some of these features from ground level one day. Layering in upper walls of Valles Marineris.

Hi Andrew, Fanstastic pictures. The one from Hellas is imho another reason for supporting a landing there, in spite of the -38Â° latitude. = /> combines sediments, unearthed (or unmarsed!) terrain, effect of ice suspected, one of lowest points with highest pressure and expect-able concentration of formerly dissolved substances. Best regards.

h2ouniverse · Jan 30, 2008

I went to GoogleMars recently. How out-of-date it now looks, when compared with all these pictures from MRO! How can we lobby so that GoogleMars becomes like GoogleEarth, a real zoomable ball with real color terrain?

3488 · Jan 31, 2008

Interesting HiRISE releases this week. Wednesday 30th January 2008. Possible salt in Noachis Terra. Possible MSL landing site in Nili Fossae. Clay minerals in the N W Bosporos Montes. Possible MSL landing site near Mawrth Vallis. Layering & slope streaks in Henry Crater. Previously flooded area in Terra Sabaea. Source of Basaltic Sand. Aolian features in Arabia Terra. Aurorae Chaos. Andrew Brown. <div class="Discussion_UserSignature"> "I suddenly noticed an anomaly to the left of Io, just off the rim of that world.

h2ouniverse · Jan 31, 2008

Hi Andrew, All images amazing, as "usual". The ones from Arabia Terra exhibit a sharp contrast with very dark (flat?) terrain. To your knowledge, has the contrast been enhanced? Regards.

3488 · Jan 31, 2008

Hi Joel, It is always a pleasure to find this sort of thing & bring it to the Community. <img src="/images/icons/laugh.gif" /> Whilst I cannot say for 100% sure, It does look to me to be an enhanced image. The reason obviously is to tease out the maximum information possible. Yes, that dark terrain looks flat to me also. If there is any relief on that dark terrain, then it is very low. What do you make of the salt in Noachis Terra or the ancient flood in Terra Sabaea? Shame that Terra Sabaea is too far north @ 41 degrees 48' North for the MSL.

Salt lands and flooded lands are great to me (as a landing site I guess?), provided that they are the lowest point of a very large basin (and subsequently not too high!). So that they could concentrate enough water. I would prefer clays over salts (as salt might have altered bio-tracers over time). My criteria are for critters not craters. (oops I did it again) Regards - Joel

billslugg · Feb 6, 2008

Andrew There is a really nice cluster of about 15 craters around pixel (17600, 4800) in "Foor of Valley within Coronae Scopulus". Unlike any I have seen in my close inspection of 70 HiRise images. You must use the IAS viewer and download the non-map projected version to see it with those pixel numbers. Otherwise, it is 88% of the way to the right and 88% of the way to the top. While you are there - look at (8430,28250) or (12500,25000). Are these: - Lines of craters that somehow induced drainage lines between them? - Drainage systems with associated sinkholes? - Meteors that just happened to strike in river beds? <div class="Discussion_UserSignature"> </div>

h2ouniverse · Feb 7, 2008

Thanks Andrew and Bill, Very interesting indeed. I hope the terrain is not too sandy (for a landing!). I wonder too how the lowest terrain is (the one at -8, -9km). Best regards.

3488 · Feb 7, 2008

You are very welcome Joel. Thanks also to Bill for his tip off. My computer got hung up on the IAS viewer, but I will try it again. Would love to see that area Bill mentioned. It is a very interesting part of Mars. I vonder if the terrain being so low, dust will accumulate, thus posing a serious problem for landing?? HiRISE will show us.
