Astronaut Scott Kelly's yearlong mission is one for the NASA history books.
He is now at home after spending 340 days in space. The 52-year-old Scott Kelly with his colleague Mikhail Kornienko touched down in Kazakhstan at 11.26 p.m GMT on March 1.
He drank nearly 200 gallons of recycled urine and sweat, collected from himself and everyone else on board.
He snapped hundreds of breathtaking pictures of the home planet and posted them on Instagram and Twitter as @StationCDRKelly. Here are some of the best pictures:
