On June 10, 2018, a dust storm swept across Mars and covered NASA's Opportunity Rover. The rover fell silent to survive the storm, but after eight months of trying to "revive" the rover, NASA Opportunity declared dead on February 13, 2019.
But before Opportunity shut down, she had completed the last marpanorama. The shot, a 360-degree view of the surface of Mars, consists of 354 images taken from May 13 through June 10, 2018, using the Opportunity's Panoramic Camera (or Pancam), a planet it has been exploring for 15 years would have.
The image above is a false color image, so most features are more visible. However, you will notice that some points in the lower left corner are black and white. This is because the rover did not have time to pick up these spots with its green and purple filters before the dust storm broke in and blocked Rover's solar panels.
"This last panorama epitomizes what made our opportunity rover a remarkable exploration and discovery mission," said John Callas, Opportunity Project Manager, NASA's Jet Propulsion Laboratory. (You can also see a larger version of the photo shown here at this link.)
"To the right of the center you can see the edge of the Endeavor crater in the distance, just to the left of which Rover traces begin their descent from the horizon and meander to geological features that our scientists wanted to investigate on the left are the bottom of the Perseverance Valley and the bottom of Endeavor Crater, untouched and unexplored waiting for future explorers to visit.
