Third all-female spacewalk successfully completed

It took NASA more than 50 years to stage its first all-female spacewalk in October. It took three more months before the second on January 15, and just five days more before the third on Monday, a successful six-hour 58-minute excursion to finish installing a set of new solar array batteries aboard the International Space Station.

Floating in the station's Quest airlock compartment, Jessica Meir and Christina Koch switched their spacesuits to battery power at 6:35 a.m. EST to officially kick off their third spacewalk together, the 226th devoted to station assembly and maintenance.

Once outside, the astronauts quickly made their way to the outer-most set of solar arrays on the left, or port, side of the station's power truss. Over the next five-and-a-half hours or so, they completed work started during spacewalks last year to install new lithium-ion batteries, replacing aging, less powerful nickel-hydrogen units.
