NASA’s Scott Kelly returned to Earth today after 340 days in space, the longest voyage by a U.S. astronaut. While aboard the International Space Station, Kelly captured—and tweeted—intriguing images of Earth’s mountain ranges from the Aleutian Islands down to Patagonia. Alongside pictures of frozen lakes, ice fields and snow-capped volcanoes, here are Kelly’s most striking photos of Ski Country from space.
