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.

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.
Opportunity worked along Endeavour Crater's western rim through November, taking pictures, hiking slopes, and finishing work in the depths of Cape Tribulation.

Opportunity spent the month of October on Spirit Mound studying the rich yet familiar geology at the first science stop on its 10th extended mission – pausing only to take a shot at freeze-framing part of the descent of Europe’s Schiaparelli lander.

It was another September to remember for Opportunity as she cruised through the Lewis and Clark Gap and out of Marathon Valley, then hiked downslope, leading the first overland expedition of the Red Planet to Spirit Mound, a new site deep in Endeavour Crater’s rim.
