Science is the key to our future, and if you don't believe in science, then you're holding everybody back.

You can believe what you want religiously. Religion is one thing, but science, provable science, is something else.

When we see the shadow on our images, are we seeing the time 11 minutes ago on Mars? Or are we seeing the time on Mars as observed from Earth now? It's like time travel problems in science fiction. When is now; when was then?

If you're an adult and you choose not to believe in science, fine, but please don't prevent your children from learning about it and letting them draw their own conclusions.

There's nothing I believe in more strongly than getting young people interested in science and engineering, for a better tomorrow, for all humankind.
