Nasa astronauts make history as they begin first all-female spacewalk

CREDIT: NASA US astronauts Christina Koch and Jessica Meir made history as they floated out of the orbiting space laboratory 12 minutes ahead of schedule at 12.38pm BST on October 18 to replace a faulty power unit. This is Ms Koch's fourth spacewalk and a first for Ms Meir, who has become the 15th woman to venture out of the ISS and into the vacuum.
