NASA Astronaut Scott Kelly is back on Earth after spending a year in Space. Kelly touched touched down late Tuesday night at 11:30 p.m. after a long journey from the International Space Station.
It took Kelly and a Russian Cosmonaut three and a half hours to reach Kazakhstan from the I.S.S. The pair spent 340 straight days 250 miles above Earth circling the globe together more than 5400 times. Just before leaving the I.S.S. Kelly said being in space is a feeling you never quite get used to.
Kelly and his twin brother, former astronaut Mark Kelly, have also been taking part in NASA's "twins study." The space agency is looking at how the identical twins measure up after a year with Scott in space and Mark on Earth.
Scott must now get a very thorough medical exam because according to researchers, Kelly's time spent in Space with no gravity may have caused his bones to become more brittle and his eyesight may also have changed.
Kelly says after almost a year in Space the first thing he wants to do is jump in his pool back in Houston, Texas.
