epa07940115 A handout photo made available by NASA shows NASA astronaut Christina Koch taking an out-of-this-world 'space-selfie' with the Earth behind her, 18 October 2019 (issued 22 October 2019). NASA astronauts Christina Koch and Jessica Meir ventured into the vacuum of space for seven hours and 17 minutes on 18 October 2019, to swap a failed battery charge-discharge unit (BCDU) with a spare during the first all-woman spacewalk. The BCDU regulates the charge to the batteries that collect and distribute solar power to the orbiting laboratory's systems. EPA/NASA HANDOUT HANDOUT EDITORIAL USE ONLY/NO SALES
