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

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

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

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

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.

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

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