We're driving into our own images every day.

I look forward to every day when I come in, to see what new data has come from the rover. Since we're driving around, it really is new every day.

Seeing all of them takes a serious amount of time. I try to look at all of them every day, but if you take the weekend off, you're a few hundred images behind.

These images are going to be studied for years, decades, because there's just so much data. The data set is for the ages.

Gasoline supply and prices are driving things. The fall in crude stocks was a big surprise.

My mom and I had to sneak Fred into the hotels. We'd be driving all day, it would get to 8 o'clock, and Mom and I are smuggling in this large cat carrier and a stack of these disposable litter boxes.
