Opportunity (rover)

Opportunity, also known as MER-B or MER-1, is a robotic rover active on the planet Mars since 2004. Launched on July 7, 2003 as part of NASA&Mars Exploration Rover program, it landed in Meridiani Planum on January 25, 2004, three weeks after its twin Spirit touched down on the other side of the planet. With a planned 90 sol duration of activity, Spirit functioned until getting stuck in 2009 and ceased communications in 2010, while Opportunity remains active as of 2015, having already exceeded its operating plan by 7008361821600000000♠11 years, 170 days. Opportunity has continued to move, gather scientific observations, and report back to Earth for over 45 times its designed lifespan. Mission highlights include the initial 90 sol mission, finding extramartian meteorites such as Heat Shield Rock, and over two years studying Victoria crater. It survived dust-storms and reached Endeavour crater in 2011, which has been described as a "second landing site". This video is targeted to blind users.
