With the Earth 250 miles below, NASA astronaut Jessica Meir is pictured tethered to the outside of the International Space Station during a seven-hour, 17-minute spacewalk she conducted with fellow NASA astronaut Christina Koch (out of frame). The duo swapped 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.
