Two NASA astronauts are installing high-definition TV cameras during a spacewalk at the International Space Station.
ISS Commander Drew Fuestel floated out Thursday with Ricky Arnold.
They're installing cameras meant to provide sharp views of new crew capsules coming in to dock at the ISS.
Until Space-X and Boeing start flying astronauts, NASA must rely solely on Russian capsules for getting to and from the space station.
Russian rides cost NASA up to $82 million per person.
NASA hasn't launched astronauts into space from U.S. soil since the last shuttle flight in 2011.
Space-X and Boeing are aiming for test flights from Cape Canaveral, Florida, by year's end.
