As Scott Kelly prepares to blast back to Earth after a record-breaking year spent on the International Space Station, he thinks about what brought him here and what awaits him at home. Scott's partner-in-crime is his twin brother, Mark. They spent their childhood getting in and out of scrapes. They had a talent for finding trouble and taking risks, which turned out to be great training for the biggest risk of all -- space travel. Along the way to becoming astronauts, they learned to be peacemakers, to stay calm in the toughest of times, to support their family, to work hard and take small steps towards their goals. Scott learned that he needed people to believe in him, as his principal did, even though he was at first a terrible student who couldn't sit still. All of these skills served him well during his year on the ISS, where he and his crew ran 400 experiments and he himself became a test subject. The sacrifices Scott made, the dangers he faced and the sight of our beautiful planet from space made coming home even sweeter.
