WATCH: NASA astronauts on spacewalk outside ISS

Two NASA astronauts stepped outside the International Space Station Thursday to install a pair of high-definition cameras.

The cameras are designed to provide sharp views of commercial crew capsules coming in to dock.

Boeing and SpaceX are slated to do their first test flights to the ISS in August.

Video was captured of ISS commander Drew Feustel and astronaut Ricky Arnold on their spacewalk.

They were also tasked with changing camera equipment and addressing additional maintenance items.
