This whole mission has surpassed all of our expectations.
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' past. It's sort have been the good luck rover for this whole thing.
There is certainly talk of getting another extension.
We're stunned by the diversity of rocks. This stuff looks like it was put into a blender.
It sounds like a crazy way to land on Mars, but it's actually tried and tested.
It has everything a human field biologist has and then much, much more.
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 place to go.
The rocks, to a great extent, look swept clean. It's a much cleaner surface than what we had a right to hope for.
For much of its history, it was a very forbidding place.
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.
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 like.
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 came from, by which I mean we can learn how life came about.
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.
Having been given that public trust, we have a responsibility to share with the public.
That's really what science is just trying to figure stuff out, and I like figuring stuff out.
