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 wrapping the final science investigations on the slopes of Cape Tribulation, Opportunity climbed up and over the rim of Endeavour Crater in March and embarked on the journey south toward its next science target: Perseverance Valley.
Driving the Mars Exploration Rovers (MER) mission further into its fourteenth year of surface operations, Opportunity continued hiking the slopes of Cape Tribulation in February and finally reached the crest of Endeavour Crater’s western rim.
2017 got off to a start that was unprecedented in every good way: Opportunity completed her 13th Earth year of surface operations and drove the first overland expedition of the Red Planet into its 14th year.
As 2016 came to an end and 2017 rang in, Opportunity was working the first leg of the ascent up the rugged western rim of Endeavour Crater on her way to an ancient gully, the next scientific tour de force down the road, and the mission was closing in on its 13th anniversary of surface operations coming up in the New Year.
