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.
We didn't know if the rover could climb up or down the hills of the crater.
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.
We're stunned by the diversity of rocks. This stuff looks like it was put into a blender.
