Opportunity was the second of the two rovers launched in 2003 to land on Mars and begin traversing the Red Planet in search of signs of past life. The rover is still actively exploring the Martian terrain, having far outlasted her planned 90-day mission.
Since landing on Mars in 2004, Opportunity has made a number of discoveries about the Red Planet including dramatic evidence that long ago at least one area of Mars stayed wet for an extended period and that conditions could have been suitable for sustaining microbial life.
