In 2003, twin Mars Rovers will be launched towards the Red Planet. Once on the surface, the Rovers will be able to travel significant distances and use several instruments to help scientists determine the climate and water history in Mars' present and past.

Type in your name and send it to Mars. Once you have done this you will receive a "Success" page where you will be able to print a commemorative certificate and bookmark it for later viewing. All the names collected will be recorded onto a small DVD disk that will be attached to the lander that will travel to the surface of Mars.
