That's really what science is just trying to figure stuff out, and I like figuring stuff out.

Is there water still on Mars? I don't have a view on that because we don't have good data to answer that question. One of the biggest mistakes you can make if you're a scientist is to think you know the answer, or wish for a certain answer, before you actually have it.

The rocks, to a great extent, look swept clean. It's a much cleaner surface than what we had a right to hope for.

We didn't know if the rover could climb up or down the hills of the crater.

I can't ever remember not wanting to be a scientist.

These rovers are living on borrowed time. We're so past warranty on them. You try to push them hard every day because we're living day to day.

There's no way to actually turn the rover off.
