Video: Highlights of second Expedition 50 spacewalk

A U.S. Army veteran of Operation Desert Storm, a Russian Air Force MiG-29 fighter pilot, and a former flight controller for Russia’s Mir space station arrived at the International Space Station on Friday, with a smooth docking aboard a Soyuz spaceship at 0952 GMT (5:52 a.m. EDT), two days after a successful launch from Kazakhstan.

Astronauts Christina Koch and Jessica Meir carried out history’s first all-female spacewalk Friday, floating outside the International Space Station and successfully installing a 230-pound replacement battery charger in the lab’s solar power system. The historic excursion was carried out in a blaze of public interest that rose all the way to the White House.

Two astronauts worked outside the International Space Station Wednesday to reposition two spare solar array ammonia coolant pump assemblies, putting a failed unit, dubbed “Leaky,” into long-term storage and attaching another, known as “Frosty,” to an appendage of the lab’s robot arm.
