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.

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

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.

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

At this point, we're still very confident that we're in orbit in Mars and that we're going to see the spacecraft signal in a few hours.

It's a nuisance having to park. It's very expensive.
