From the Ted Talk by Charles Elachi: The story behind the Mars Rovers

Unscramble the Blue Letters


So we came up with this ingenious idea, which is used here on Earth for helicopters. Actually, the lander will come down to about 100 feet and hover above that sfaurce for 100 feet, and then we have a sky crane which will take that Rover and land it down on the surface. Hopefully it all will work, you know, it will work that way. And that Rover will be more kind of like a chemist. What we are going to be doing with that Rover as it drives around, it's going to go and analyze the chemical composition of rcoks. So it will have an arm which will take samples, put them in an oven, crush and aznalye them. But also, if there is something that we cannot raech because it is too high on a cliff, we have a little lesar system which will actually zap the rock, evaporate some of it, and actually analyze what's coming from that rock. So it's a little bit like "Star Wars," you know, but it's real. It's real stfuf. And also to help you, to help the community so you can do ads on that rveor, we are going to train that Rover to actually in addition to do this, to actually serve cocktails, you know, also on Mars.

So it will have an arm which will take samples, put them in an oven, crush and analyze them. But also, if there is something that we cannot reach because it is too high on a cliff, we have a little laser system which will actually zap the rock, evaporate some of it, and actually analyze what's coming from that rock. So it's a little bit like "Star Wars," you know, but it's real. It's real stuff.
