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.

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

There is certainly talk of getting another extension.

I’ve always felt that we had six terrifying events in this mission; two launches, two landings and two egresses, … And it wasn’t until both [rovers] were in their native environments on Mars, for me,...

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.

It was evidence that water at one time had saturated the ground here.

It’s a cold, dry miserable place today. But we have got these tantalizing clues that, in the past, it used to be warmer and wetter,

This whole mission has surpassed all of our expectations.

The Beagle 2 is excellent, ambitious. Ours are excellent, but we have different instrument packages and different aims. I don’t see the material for the controversy,

When you look at the most important accomplishments of the mission, a lot of them were due to Opportunity. It was the one that found the really powerful evidence for a habitable environment in Mars’...

When we opened our eyes, we saw bedrock exposed in the walls of the crater.

We’re stunned by the diversity of rocks. This stuff looks like it was put into a blender.

It’ll be spectacular if we can get there.

It sounds like a crazy way to land on Mars, but it’s actually tried and tested.

We need to drive like hell and get to the hills before the winter sets in.

It has everything a human field biologist has and then much, much more.

Having been given that public trust, we have a responsibility to share with the public.

The search is difficult to achieve in a single mission. When we do a mission that is aimed at finding extant life, which probably requires liquid water at the surface, we will know exactly the...

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

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 want to make as many people as possible feel like they are part of this adventure. We are going to give everybody a sense of what exploring the surface of another world is really...

You create a pile of dirt and then drive over it. We may have to learn to drive all over again.

For much of its history, it was a very forbidding place.

It’s not going to fill in the potholes. It’s not going to put a roof over people’s heads. What it does is it helps to address really fundamental questions of who we are, where we...

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