Mars Express Sends Back Stunning Image of Ice-Filled Korolev Crater

January 02, 2019

Scientists are still unsure if liquid water exists on Mars, but we know there’s plenty of water ice. The ice on Mars is usually diffuse and found in small pockets mixed with frozen carbon dioxide, but the Mars Express probe just beamed back images of a massive deposit of pristine water ice in an impact crater. This isn’t a new discovery, but it’s the best photo we’ve ever gotten of the Korolev crater.
