Curiosity is the hip name in Mars-rovin, but the Opportunity rover was doing it long, long before. Just yesterday Opportunity hit its 10-year anniversary on Mars — it left Earth 10 years ago in July. Not bad for a mission intended to last a mere three (Earth) months. In celebration it sent back a selfie.
