What will we do without our daily dose of Scott Kelly in space? I’m pretty bummed. I still haven’t accepted the fact that his Twitter feed will no longer be dosed with photos of his journey. However, thanks to his #YearInSpace, we’ve got tons of amazing photos (over 1,000, as he mentions below), and NASA, well they got some serious advance deep space exploration under their belt thanks to Kelly and his Russian counterpart Mikhail Kornienko.

During the year mission, the station crew conducted almost 400 investigations to advance NASA’s mission. Kelly and Kornienko participated in a number of studies to inform NASA’s Journey to Mars, including research into how the human body adjusts to weightlessness, isolation, radiation and the stress of long-duration spaceflight.

Another super interesting tidbit, while Kelly was in space, his identical twin brother, former NASA astronaut Mark Kelly, did parallel twin studies on Earth to help scientists compare the effects of space on the body and mind down to the cellular level.

Now let’s get to the good stuff—photos and Tweets galore from Kelly’s #YearInSpace. Follow @StationCDRKelly on Twitter to trail his new journey rediscovering Earth!
