Now we are not dealing with kids having fun. We are dealing with criminals -- the Russian mafia. And online banking risks are there if your bank offers it, even if you don't use it.

We have very much personified these vehicles. We think of them as our children, because they have very human characteristics. They see, they move, they interact, they respond to our commands, and they think on their own.

If it has failed, it will be a significant hit. It is the contact arm of the mission.

Something could just break and that will be it for the rover. There could be one day when the rover has a massive stroke and it will be over.

There's no question there were standing bodies of water at the surface. Victoria is a potential time tunnel, allowing access to ancient martian material that otherwise would be buried deep beneath the surface.

Every day is like a brand new mission to us, because the rovers move. And so we are in different locations, there is different terrain, there is different geology, there is something new to explore. We're like Lewis and Clark going upriver and every day there's new phenomena to see.

Some of our most significant discoveries came well after the initial 90-day prime mission.

It is reasonably valuable if you can convince someone to steal from other people.
