On this day in 2004 – January 25th – the Mars rover Opportunity landed on the red planet.

The mission was designed to last 90 Martian days, but it was operational until the summer of 2018 when an exceptionally severe dust storm blanketed Mars for three months. The rover didn't recover from the loss of power, and the mission was officially brought to an end in February 2019.
