Brian Wilcox, a man who worked on the Spirit and Opportunity Rovers that are still working on Mars are now looking at making another rover for exploring the Moon. People have been to the moon so why are we going back? In the 1960s, the Soviet Union (now Russia) and the United States were in a race to the Moon. In 1969, man landed on the moon with Apollo 11 and Neil Armstrong. In 1972, Apollo 17 was the last US mission to the moon. We stopped making the rockets that got us to the Moon and have used the Space Shuttle ever since. The Shuttle can only circle the Earth.
Now we are in another space race to go back to the Moon. China, India, and the European Space Agency have sent probes to study the moon. We no longer have the ability to make the old Apollo rockets and we have to start again. Robots will go back before man. For 9 questions about Robotics and NASA look here.
