Waking up hundreds of miles above the Himalayas, astronaut Scott Kelly broke the U.S. record Friday for the most time spent in space: 383 days.
Kelly is more than halfway through a yearlong mission at the International Space Station and will eventually set a record for the longest single U.S. space mission.
Kelly tweeted back to Earth that he hopes that his eventual 500-plus days in orbit will be exceeded by someone visiting Mars. He tweeted that his day began with a strikingly beautiful view of the Himalayas and vowed to visit them.
Kelly and his ex-astronaut twin, Mark, on the ground, are part of an experiment on the long-term effects of space.
Russia's Gennady Padalka holds the record with 879 days in space.
