Posted by 3488</DIV> I hate to be repetative, but.... Wow Andrew, rather nice that we have a chance to catch our breaths and check up on our other projects. Sure as heck looks like there's a lot going on in that crater. It doesn't seem unreasonable to suggest a lot of the "white" in the crater has a lot to do with the small but very fresh crater above and to the right. Interesting that the older crater in the same direction doesn't seem to show such activity. Perhaps there is a prevailing flow that moves material in that direction.

Posted by MeteorWayne</DIV>Hi Wayne,Of course Phoenix has & will for a little while yet, hog the limelight, but I have not forgotten MESSENGER, DAWN, the MERs, etc. Phoenix though will not & physically cannot have the longevity of MESSENGER, DAWN & the MERs.The Martian arctic will take care of a solar powered spacecraft, as Autumn arrives.The crater is on the south western side of the Caloris Basin. Looking at the overlapping lava flows, the tend the overlap towards the bottom left, as would be expected for this location.A guess, just as you say based on that remarkable NAC photograph is the ground descends from top right to bottom left.So your theory of the smaller crater blasting stuff into the larger Kertész Crater  makes sense, as impact material is more likely to roll down hill in Mercury's fairly substantial gravity (the surface gravity is 37.7% of Earth's. Mars's is 37.8% of Earth's only one part in 377 stronger than Mercury's).I think you had mentioned earlier in this thread that impact ejecta is more likely to roll than be hurled huge distances, as on smaller bodies. I think this is a good case in point.Also the face that the floor & the inner S.W terracing of Kertész Crater, rather than the N.E terracing, also supports this idea. Despite what's happening with Phoenix, MESSENGER is never that far away from my thoughts & am still looking forward immensely to the October encounter.Andrew Brown. <div class="Discussion_UserSignature"> "I suddenly noticed an anomaly to the left of Io, just off the rim of that world.
