Astronaut Scott Kelly announces his retirement after spending nearly a year in space. On Friday, NASA reviles Mr. Kelly’s retirement, less than two weeks after Kelly landing on Earth. He leaves the space agency on April 1.
The 52-year-old Kelly made a U.S.- record 340 days in orbit on International Space Station to see how the human body holds up for long periods of time in space.
His results are being compared to those on the ground from his twin brother, Mark, who is a retired astronaut.
Scott Kelly also holds the American record for most time in space- 520 days over four missions.
“I look forward to continuing my 30 years of public service in a new role,” Mr. Kelly, who joined the Navy in 1987, said in a Facebook post. “To continue toward any journey, we must always challenge ourselves to take the next step.”
“This year-in-space mission was a profound challenge for all involved, and it gave me a unique perspective and a lot of time to reflect on what my next step should be on our continued journey to help further our capabilities in space and on Earth,” Mr. Kelly said in a statement issued by NASA.
