NASA astronauts are undertaking a six-and-a-half hour spacewalk Friday morning to install a new dock on the International Space Station.
Astronauts Kate Rubins and Jeff Williams began the spacewalk shortly after 8am EST. You can watch a live broadcast streaming their work above.
The new dock will be used in 2017 by private companies Boeing and SpaceX to bring their crews to the International Space Station. Much of the work on the dock was prepared before the international docking adapter was delivered by SpaceX on July 20.
This is Rubins’ first spacewalk and Williams’ fourth.
