VideoLong-awaited station spacewalk on tap Friday
Astronauts Jeff Williams and Kate Rubins ventured outside the lab complex Friday for a long-awaited spacewalk to attach a new docking mechanism, the first of two that will be used by U.S. crew ferry ships being built by Boeing and SpaceX to carry astronauts to and from the outpost, ending NASA's sole reliance on Russian Soyuz spacecraft.
VideoBlue Origin launches same New Shepard spacecraft for third time
