Video: Expedition 50 spacewalk highlights

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.

Clad in pressurized spacesuits, two Russian cosmonauts headed outside the International Space Station on Wednesday and hand-released four tiny CubeSats and installed hardware for a German experiment to track animal migration.

Russian mission control said Thursday an unpiloted Progress space station supply ship carrying nearly 5,400 pounds of rocket fuel, food, water and a new spacesuit burned up in Earth’s atmosphere shortly after it blasted off from Kazakhstan, and evidence points to a problem with the third stage of the cargo carrier’s Soyuz booster.
