NASA astronauts Christina Koch and Andrew Morgan are embarking on their first spacewalk outside the International Space Station on Sunday, 6 October.
They are expected to set up new lithium-ion batteries that were delivered last week on board Japan's HTV-8 cargo aircraft.
Koch has spent 200 days in the space station; she arrived at the International Space Station (ISS) in March and is slated to undertake the first all-female spacewalk with astronaut Jessica Meir on 21 October.
Andrew Morgan had his first spacewalk in August, alongside his colleague Nick Hague.
