Opportunity's twin, on the opposite side of Mars in Gusev Crater. Lost a front wheel motor in 2006 and kept going in reverse. Found silica-rich soil at Home Plate. Got stuck in soft sand at Troy in 2009 and could not tilt toward the Sun for winter.

Stuck in soft sand at Troy. Can't tilt my panels toward the Sun for winter.

Going to sleep. Tell my twin I said hi.

    Still driving on the other side of the planet. I'll keep the odometer going for both of us.
