A series of meteor strikes on Mars have uncovered pure water ice—and maybe liquid water—in the red planet’s relatively balmy mid-latitudes.

Sharp-eyed spacecraft discovered the ice when several meteors slammed into Mars’s surface and created five craters some 1.5 to 8 feet (0.5 to 2.5 meters) deep and 26 feet (8 meters) in diameter.

A single meteor shower created the craters, which revealed bright blue ice that vaporized in about 200 days. Above, the left column shows four separate craters right after the impact, and right, the same craters after the ice had mostly vaporized.
