Curiosity rover

If there's life on any other planet in our solar system, it's probably on Mars. Scientists have sent orbiters, landers, and rovers to the Red Planet in search of clues of life. The Curiosity rover
is the latest and most advanced step in this quest. This one-ton science lab will land on Mars inside Gale Crater, which may be a dried up lake. Using scientific instruments, the car-sized rover will examine the crater for signs of past or present life.
