This timelapse video from the International Space Station shows ESA astronaut Luca Parmitano helping NASA astronauts Andrew Morgan and Christina Koch prepare for a spacewalk on 6 October 2019.

Andrew and Christina worked outside in the vacuum of space for seven hours and one minute to begin the latest round of upgrading the station's large nickel-hydrogen batteries with newer, more powerful lithium-ion batteries.

This spacewalk is one of many scheduled for October and November. The first all-female spacewalk is expected to take place during the week of 14 October and Luca is expected to complete his first spacewalk of the Beyond mission later in November.

During his November spacewalks, Luca will work to repair and enhance the Alpha Magnetic Spectrometer – a particle physics experiment module that was never designed to be maintained in orbit.
