The Curiosity rover has been exploring Mars since it landed in August 2012 as part of NASA’s Mars Science Laboratory mission.

The rover was launched from Cape Canaveral on November 26, 2011.

In December 2012, the rover’s two-year mission was extended indefinitely.

The Curiosity rover recently started drilling into the surface of Mars again after a nearly two-year break due to a mechanical issue.
