NASA astronaut Christina Koch takes an out-of-this-world "space-selfie"

iss061e011828 (Oct. 18, 2019) --- NASA astronaut Christina Koch takes an out-of-this-world "space-selfie" with the Earth behind her. She and fellow NASA astronaut Jessica Meir (out of frame) ventured into the vacuum of space 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.
