Commander Scott Kelly has just returned from his 340-day mission aboard the ISS. The record breaking mission has seen Kelly and Russian cosmonaut Mikhail Kornienko spend almost a year in space, and scientists hope to gain an insight into what long stays in microgravity do to the body, with views on missions to Mars in the future.
Over the last year, Commander Kelly has not only been in charge of the ISS and conducted important scientific experiments, but he has also been an avid scientific communicator, posting incredible photos on his Twitter page. Here’s a selection of his best shots.
