"My battery is low and it's getting dark" — the rover that ran for 14 years.
This is Perseverance Valley on the rim of Endeavour Crater, where NASA's Opportunity rover sent its final signal in June 2018. Built for a 90-day mission, "Oppy" lasted nearly 15 years and drove over 45 km — the longest distance ever traveled on another world.

Instead it explored Meridiani Planum for nearly 15 years, finding hematite spherules and rock textures that proved liquid water once flowed here. Its odometer eventually passed a full marathon — 42.2 km — a distance no machine had ever driven on another planet.
In June 2018 a planet-encircling dust storm blotted out the sun, and the solar-powered rover went quiet. Its last data has been poetically paraphrased as "My battery is low and it's getting dark." After hundreds of recovery attempts, NASA declared the mission complete on February 13, 2019.
