Spirit is one of two rovers that NASA launched to explore the planet Mars, the other Opportunity. Landing on the Red Planet in 2004, Spirit sent fantastic images and videos of natural events and features of Mars. In 2010, the rover lost communication with NASA, and the next year, on Memorial Day, NASA annouced the rover's mission ended.
1 million years after people Spirit has suffered minimal damage from Martian dust storms, but the rover is still recognizable, but it's buried under the Martian surface. Since Mars's atmosphere doesn't contain any water, corrosion doesn't occur, allowing Spirit to outlast anything manmade on Earth.
