After spending nearly a year in space, astronaut Scott Kelly is hanging up his spacesuit.
Nasa announced Kelly’s retirement on Friday, less than two weeks after he returned to Earth. He’s leaving the space agency on 1 April.
Kelly, 52, spent a US-record 340 days in orbit on the 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.
During his one-year trip, Scott Kelly posted hundreds of images, mostly of Earth from orbit, on social media. But he also engaged in a little fun, donning a gorilla suit that was a gag gift from his brother and chasing fellow astronauts through the space station in a video.
“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,” Kelly said in a statement.
No specific plans for what’s next were announced. But Kelly will continue to undergo periodic medical tests as part of his mission, NASA said.
“Adjusting in space is easier than adjusting to Earth for me,” Kelly said in his first postflight news conference a week ago. Even then he gave a hint of what was to come, saying he doubted he’d fly again for Nasa but adding, “I’ll never be done with space. I will always be involved.”
Kelly’s departure means the space agency is losing its biggest star, said John Logsdon, a retired space policy professor.
“I’m willing to bet that no one could name another Nasa astronaut, anyone not close to the program,” Logsdon said. “It clears the way for the next generation of space fliers. There are a few veteran fliers left, but not many.”
Nasa administrator Charles Bolden, a retired astronaut himself, said the space agency and science in general is grateful to Kelly, who he added deserves “meals that don’t come in a bag, a cold beer, hot showers, cool autumn breezes, the sounds of birds chirping, the ability to lay his head on an actual pillow and so much more of the pleasures of life.”
Those who eventually will land on Mars “will be following in the footsteps of one of the finest astronauts in the history of the space program, my friend, Commander Scott Kelly,” Bolden said.
Kelly returned from the space station on 2 March, landing in Kazakhstan with Russia’s Mikhail Kornienko, his mission.
His re-entry into land living was good and bad. Home in Houston, he dove into his backyard pool still in his blue flight suit, going underwater for the first time in nearly a year. But clothing was a problem. In space, his clothes floated around him and didn’t touch his skin.
“It’s very, very sensitive,” he told reporters last week. “It’s almost like a burning feeling wherever I like sit or lie or walk.”
Kelly said he was looking forward to having more options in his life: “From having so little on the space station and so few choices about what you’re going to do every day, what’s available to you, to basically having just about anything,” he said.
Before leaving orbit, Kelly tweeted: “The journey isn’t over. Follow me as I rediscover #Earth!”
