This thread is intended for comments and questions regarding the Opportunity Mars Exploration Rover and the updates published under the topic: NASA's Opportunity roves Mars (2010-Present).

Opportunity and its rover twin, Spirit, completed their three-month prime missions on Mars in April 2004. Both rovers continued for years of bonus, extended missions.

Spirit finished communicating with Earth in March 2010.

Both Spirit and Opportunity have made important discoveries about wet environments on ancient Mars that may have been favorable for supporting microbial life.
