The Opportunity rover is the second rover in NASA's Mars Exploration Rover program, which sent twin rovers to Mars in 2004 with the goal of searching for evidence of the former presence of water on Mars. It was initially designed to last for only 90 days on Mars (sol). However, Opportunity has repeatedly cheated death, escaping from sand dunes and even a dust storm in 2007, making it the longest-operating rover on Mars. It also traveled further than any other rover has ever traveled, covering more than 50 kilometers, and sent back a wealth of scientific data and empirical evidence. Today, we can confidently confirm that Mars was once a moist, watery place, just like our own Earth. Join Opportunity on the adventure with us at Spaceth in this video.
