The surface has got to be free of really large rocks, and you want to make sure that there is available water ice within easy walking distance. You can't necessarily guarantee the rovers are going to work to start with so you want to be able to walk there and walk back. And you want to also make sure that you can get off there again. So that's why you need the available water ice because you want to make the fuel to get back to Earth again afterwards.

People have always explored. People have explored right from the moment that humans first evolved. If there's something over the horizon, people are going to go there. And so Mars is literally just over the horizon. It's a bit further away than Venus, but it's much more habitable. So we might as well get ready to find out what we need to know and how we need to know it. And that's just a matter of learning what we can about it.
