iss061e011934 (Oct. 18, 2019) — NASA astronaut Christina Koch prepares to exit the crew lock portion of the Quest airlock into the vacuum of space. She and fellow NASA astronaut Jessica Meir (out of frame) conducted a spacewalk for seven hours and 17 minutes 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 lab’s systems.
