Video: Highlights of second Expedition 50 spacewalk

With plans for the first all-female spacewalk derailed by suit sizing issues, astronauts Christina Koch and Nick Hague floated outside the International Space Station Friday for a revised excursion to help fix a solar array battery problem and to connect a second set of replacement batteries as originally planned.

Astronauts Reid Wiseman and Barry “Butch” Wilmore floated outside the International Space Station and, after a bit of trouble with a balky bolt, replaced a broken voltage regulator in one of eight solar power channels to restore the lab’s electrical grid to normal operation.

NASA astronauts Nick Hague and Drew Morgan completed a 6-hour, 32-minute spacewalk outside the International Space Station Wednesday to help connect a newly-arrived docking port to the orbiting research outpost.
