Video: Expedition 50 spacewalk highlights

Astronauts Barry “Butch” Wilmore and Terry Virts floated outside the International Space Station Saturday and installed wiring needed for two new docking mechanisms that will be attached later this year for use by Boeing and SpaceX crew capsules.

For the second time in less than a week, astronauts will leave their quarters inside the International Space Station on Thursday to outfit a relocated docking adapter to eventually receive Boeing and SpaceX commercial crew capsules.

Japan’s sixth HTV supply ship departed the International Space Station on Friday and headed for a destructive re-entry over the South Pacific with trash and disused batteries from the research lab, but engineers will first use the spacecraft for a pioneering experiment to investigate a new way to remove space junk from orbit.
