To examine the rocks we’ve got to get to them, and Mars is very bumpy. So to deal with the bumps our engineers came up with something called a Rocker-Bogie Suspension System. It’s a very clever design that allows each of the six wheels to go up and over a rock independently while the rover itself partly toss at all.

“OK, come here guys. And stay clear watch it, watch it. Stay clear and see it gonna moving in a second. Watch, watch the wheel. Watch the wheel…”

It goes way beyond the single mission. The eventual goal is to send humans to Mars. But the first person to walk on Mars is not an astronaut today. It’s someone in high school or elementary school. “It will turn it in place then wanna get lined up just right of the…”

We’ve invested so much work, so many years, so much of our hopes and our dreams in these rovers. And then when we think about where they are going, the rider gonna get on their rocket, to trans-through space. What is gonna to be like when their parachute goes at the mark, to going through the Mars’ atmosphere?

You standing next to this little robot and you realize it’s gonna spend eternity on the surface of another world. It’s going to another planet for wheel. And once they are gone, that’s it. After the rovers launched we will never gonna to see them again with our own eyes. We’ve done everything we can to prepare for the dangerous they have to face. But it’s gonna be very hard to say goodbye.
