The view of rainbow-hued Himalayan lakes and steady work helped Scott Kelly stay sane during the 340 days he spent aboard the International Space Station (ISS), the NASA astronaut said days after returning to Earth from the record-setting mission.
Kelly and his Russian counterpart, Mikhail Kornienko, spent nearly a year on the ISS studying the effects of radiation, weightlessness and the cramped quarters of spaceflight on humans.
Besides following the news and the beautiful view, Kelly said steady work helped him sane. "I tried to have milestones that were close, like when is the next crew arriving, the next spacewalk, the next robotics, the next science (experiment). That made a difference to me, keeping my sanity," he said.
