They are great images, and the Indians should be very pleased.
Looking at those images raises a few questions in my head. I'd like to know what causes such large and unusual canyons on Mars. Here on Earth a canyon like that would have a river at the bottom and the question wouldn't really need to be raised, but on Mars there hasn't been any liquid water for a long time. It looks like the ground has slumped, forming the depression and steep slopes, so why would the ground slump?
Also, to the north there are craters, which can't be terribly old, as there is enough atmosphere to erode surface features like those, in fact what looks like erosion seems to be taking place, so how old are they?
Lots of questions and I'm sure Mars boffins will be very excited by al, the new data coming back.
