ESA astronaut Alexander Gerst and NASA astronaut Serena Auñón-Chancellor commanded the International Space Station’s 16-m robotic arm to release a Cygnus supply spacecraft to burn up harmlessly over Earth.
The duo set up the robotic workstation in the European-built Cupola module to follow operations from the observatory. You can see Alexander opening the protective shutters from a window at the start of the video.
The spacecraft was released at 14:17 GMT on 15 July 2018 as the International Space Station flew over Colombia.
Cygnus spent two weeks orbiting Earth on its own allowing engineers to conduct tests as well as releasing a series of miniature satellites before ending its mission.
