We'll begin to image the surface and look at its composition with detail that we've just not been able to do before.

Now with the new images, we're able to watch when the frost comes and goes and we can see that dunes are moving today and aren't just relics from times past.

We have not been able to find anything that would corroborate the kind of detail Lt. Col. Shaffer and Congressman Weldon seem to recall.

We don't want to be hauling cement to Mars. That's very expensive. Better to know what we can make on the surface of the planet.

These are some of the highest regions of the planet because they sit on top of southern hemisphere terrain, which is higher than corresponding terrain in the north.

It's just going to knock your socks off when we get these instruments opened up at Mars.
