About the Mars Exploration Rover (MER) Mission
NASA's Mars Exploration Rover (MER) mission has sent two robot rovers to Mars. The two robots landed at different places on Mars. The places are called Gusev Crater and Meridiani Planum. Scientists think there might have been water at each of the places in the past. Places that had water are the best places to look for signs of life. The rovers have special instruments to look for signs of water.
The two MER spacecraft blasted off in June and July of 2003. They got to Mars in January 2004. The two rovers have been given names. The first is named "Spirit" and the second is called "Opportunity".
