Scott Kelly was selected for the ‘Year in Space’ mission alongside Mikhail Korniyenko, in 2012. After years of training, their year in space began on 27th March 2015 with the start of Expedition 43 and continuing through expeditions 44 – 46 which he commanded.
This ground breaking mission was designed to assess the effects of a year in space on the human body to prepare for future longer-haul missions to Mars and beyond. This mission is particularly unique as Scott has an identical twin brother, Mark who stayed on Earth and is participating in a comparison of their bodies after a year in these very different environments.
In October 2015, Kelly set the record for the total accumulated days soent in space by an American astronaut, 382 days. He spent a total of 340 consecutive days in space as part of the yearlong mission.
On 29 February 2016, Kelly handed over command of the International Space Station to Tim Kopra, one of Tim Peake’s Expedition 47 colleagues. He returned to Earth on 1st March 2016:
