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.
With the Martian winter on the run, Opportunity cruised closer to its 14th anniversary of exploring the Red Planet in December as she deliberated a distinctive “fork in the road” deep in Perseverance Valley and wrapped another record year.
Opportunity continued the historic winter science campaign inside Perseverance Valley and delivered the goods that confirmed an important discovery in November, and then cruised through winter solstice, driving the mission closer to its 14th anniversary of surface operations coming up in January.
As brutally cold got even colder at Endeavour Crater in October, the depths of winter gripped Opportunity, and ‘life’ on Mars slowed. But the robot field geologist continued to work on through the doldrums of the season.
The Martian winter began to grip Endeavour Crater in September, slowing Opportunity's pace. But she braved the brutal cold in Perseverance Valley and followed her commands to visually document everything in sight.
Along the western rim of Endeavour Crater, Opportunity forged onward in August vicariously taking the Mars Exploration Rovers team – along with a global contingent of mission observers all around Earth – downhill into Perseverance Valley and deeper into a new chapter in this legendary expedition of the Red Planet.
