UPDATE 11:47 p.m. EST: Astronaut Scott Kelly, Flight Engineer Mikhail Kornienko and Commander Sergey Volkov have landed back on Earth.

After spending 340 days orbiting the planet aboard the International Space Station, Scott Kelly will return to Earth on Tuesday, landing near Dzhezkazgan, Kazakhstan.

In addition to setting the American record for longest total time spent in space and longest consecutive time spent in space, Kelly spent the year taking some amazing pictures, going on space walks, conducting experiments and even being a living experiment.

Scott's twin bother Mark Kelly, a former astronaut himself, stayed on Earth to serve as the "control" subject in the year-long twin study. NASA has been collecting data on Scott and comparing it to his brother's information in order to determine the various impacts extended time spent in space can have on the body.

Scott Kelly spoke with AOL.com about about how astronauts train to be mentally prepared for such a long stay away from home. "I think NASA and ... our partner agencies have a pretty good selection process for deciding who they're going to send up here as astronauts and cosmonauts ... We also do some training in ... team living, teamwork, leadership, followership ... critical skills to have for operating in such a challenging environment. For most of us ... when we get here, we're pretty well prepared for ... staying mentally strong during this type of mission.

"Occasionally you might get ... I wouldn't say depressed, but you might not feel 100% at times, and I think it's important to put the whole thing in perspective and understand the importance of what you're doing ... and [remember] eventually I'll be home someday, so that helps a little bit."
