Mars has been a source of fascination since H. G. Wells wrote The War of
the Worlds, a sci-fi fantasy of green-eyed Martians invading and
overpowering Earth. In 1971, engineers succeeded in placing a spacecraft
into Mars's orbit with the idea of finding out what was on Mars:
Intelligent life? Water? A place people on Earth could move if need be?
Since then, a number of missions to Mars have been launched. Now is your
chance to help launch the Mars Exploration Rover. Do you have what it
takes to succeed?
