NASA astronaut Scott Kelly is back on Earth after a record-setting 340 consecutive days in space, the most in NASA’s history.The space explorer landed in Kazakhstan at 11:26 p.m. ET on March 1 after spending nearly a full year on the International Space Station in an effort to understand how the human body responds to long periods of weightlessness.
Spending 340 days in space could affect a person’s vision and bones, but Kelly said last week that physically, he feels pretty good. “I could go for another 100 days or 100 years,” the astronaut said during his last briefing with reporters from orbit.
But the long stay has also been lonely. “The hardest part is being isolated from people on the ground who are important to you,” he said.
