Scott Kelly a NASA astronaut has set a new record for the most time spent off the Earth by an American citizen. Scott Kelly, who is currently serving as commander of the International Space Station’s Expedition 45 crew, marked the 200th day of what is scheduled to be a 342-day mission on board the orbiting outpost. He passed the previous record for the most total cumulative time spent in space by a U.S. astronaut of 381 days, 15 hours and 11 minutes, including the 180 days on his previous three missions.
Kelly’s 382 day record exceeded the earlier total made by astronaut Mike Fincke in 2011. Kelly is the first American to spend nearly a year in space on a single mission. Together with Mikhail Kornienko, who’s also spending 12 months in orbit, Kelly is collecting medical data to support future astronaut missions beyond the Earth to the asteroids and Mars. Kelly will set another duration record later this month. It will be the first time that an astronaut has held both the single mission and cumulative time in space records since Expedition 4 flight engineer Carl Walz in 2002, who totaled 196 and 230 days, respectively.
