At the top there is the final image Oppy ever sent out, depicting the dust storm that brought about the rover's end back on June 10, 2018. NASA has been trying to revive the Opportunity over since, to no avail. The storm knocked out its solar panels, meaning it couldn't power itself back up.
"This was the last image we ever took," Bill Nelson, chief of the Opportunity mission's engineering team at NASA's Jet Propulsion Laboratory, said. "We are looking at an incredibly small amount of sunlight -- .002 percent of the normal sunlight that we would expect to see."
After landing in 2004, Opportunity contributed greatly to our understanding of the red planet, including providing evidence that Mars once had water on its surface: close-ups of rocks bearing the marks of flowing water from billions of years ago.
Its passing has led to some strange but poignant tributes from other NASA machinery.
