The thing that sets Mars apart is that it is the one planet that is enough like Earth that you can imagine life possibly once having taken hold there.

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.

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.

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

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

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

Mars is telling us something. I'm not sure what it is because It's speaking martian. But it's telling us something

My style of leadership is to lead with the lightest touch that I possibly can.
