Cargo ships, expandables and spacewalks: ISS in 2016

Between cargo ships servicing the outpost and spacewalks to maintain it, 2016 was arguably one of the busiest years for the International Space Station since the end of the space shuttle era.

Probably the most visible event for the space station in 2016 was the yearlong crew – NASA astronaut Scott Kelly and Russian cosmonaut Mikhail Kornienko – returning to Earth. They had launched to the outpost on March 27, 2015.
