NASA team wants to send robot to moon

The real R2 ( Robonaunt 2)

NASA engineers are at work on a project to send a humanoid robot to the moon -- and they say they can do it within 1,000 days. The idea, known as Project M.

The robot would be designed to walk on the moon's surface and send back live video. Sending a robot is much cheaper than sending humans, because it doesn't need to eat or breathe, and there's no return trip.

NASA already has a humanoid robot. It is scheduled to lift off Wednesday on the shuttle Discovery bound for the International Space Station, where it will become the first humanoid robot in space. It will help with housekeeping chores at the space station. MadOne
