Every time we look closer, we see surprising new things.
Every time we look with increased resolution, Mars has said, 'Here's something you didn't expect. You don't understand me yet.' We're sure to find surprises.
We're especially interested in water, whether it's ice, liquid or vapor. Learning more about where the water is today and where it was in the past will also guide future studies about whether Mars ever supported life.
If we find evidence that (those) minerals are there, there must have been a time in Mars' early history when there was standing water on Mars' surface.
It's a weather satellite, it's a geological surveyor, it's a pathfinder for future missions.
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.
We're bringing more capability to the planet. What we're really doing now is establishing the background environment that we have to deal with when we plan future missions.
We'll begin to image the surface and look at its composition with detail that we've just not been able to do before.
Every time we have increased our ability to resolve detail on the planet, we see new things, and we expect new surprises.
