Nasa astronauts Christina Koch and Jessica Meir have made history by completing the first ever all-female spacewalk.
They spent seven hours outside the International Space Station (ISS) replacing a failed power control unit.
Ms Koch had already carried out four spacewalks but it was the first such mission for Ms Meir, who became the 15th woman to walk in space, Nasa said, reports BBC.
US President Donald Trump congratulated them in a video call.
Ms Koch, an electrical engineer, and Ms Meir, who has a doctorate in marine biology, stepped outside in their Nasa spacesuits at 11:38 GMT (07:38 EDT) on Friday.
