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.
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.
The autumn skies over Endeavour Crater remained hazy as dust from the summer storms continued to rain down, but Opportunity encountered some unexpected and serious June gloom when her right front steering wheel jammed during the walkabout atop Perseverance Valley.
In another dynamic demonstration of what can be achieved when a team works together, Opportunity cruised to the top of Perseverance Valley, shot the moon, and drove into her 160th month of surface operations in May.
