Video: Highlights of second Expedition 50 spacewalk

Russia’s next Progress cargo freighter rolled out to its launch pad in Kazakhstan on Tuesday in a final move before blasting off Thursday at the tip of a Soyuz rocket to resupply and refuel the International Space Station.

Japan’s sixth HTV supply ship is slated to depart a picturesque spaceport on Tanegashima Island on Friday to start a four-day pursuit of the International Space Station with a cache of experiments, supplies and six lithium-ion batteries to begin overhauling the orbiting lab’s vast electrical system.

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.
