Video: Expedition 50 spacewalk highlights

NASA astronaut Nick Hague will take the place of Anne McClain on a spacewalk Friday outside the International Space Station, teaming up with crewmate Christina Koch  to continue a series of battery upgrades on an excursion that would have been the first all-female spacewalk in history.

Astronauts Shane Kimbrough and Thomas Pesquet put on their self-contained spacesuits and headed outside the International Space Station on Friday for a six-and-a-half hour excursion to prepare for the relocation of a docking adapter, service the lab’s Dextre robot, and install a new computer relay box.

After 24 days at the International Space Station, SpaceX’s Dragon supply ship came back to Earth on Sunday with more than 5,400 pounds of cargo, human and animal research specimens, and other gear tagged for the trip home. Release from the station’s robotic arm occurred at 5:11 a.m. EDT (0911 GMT), and splashdown in the Pacific Ocean was a few minutes before 11 a.m. EDT (1500 GMT).
