10 years on Mars!
We're celebrating 10 years on Mars with the Mars Exploration Rovers
You can also send a personal message to the scientists and engineers responsible for these remarkable roving robots. We'll be collecting messages throughout January, so there's plenty of time to get your friends and family to send messages, too.
We hope that you explore our virtual party, play our games, see some pictures and enjoy our videos. For more in-depth coverage of the MER mission, we have posted A.J.S. Rayl's monthly articles below. You will not find a better source of MER activities.

After three weeks of being in a communications blackout on the other side of the Sun during the Earth-Mars solar conjunction, Opportunity phoned home, reporting that she is healthy and ready to continue her mission.
Opportunity spent a mostly merry month of May on Mars touring Spirit of St. Louis Crater, stopping at science targets named in honor of Charles Lindbergh and the incredible flight he took 88 years ago.
After investigating some flat, light and dark toned rocks around Spirit of St. Louis Crater in April, Opportunity chalked up another milestone achievement – the 4000th sol or Martian day of surface operations.
