Video: Change of command aboard International Space Station

NASA has delayed the award of new contracts for cargo transportation services between Earth and the International Space Station, and eliminated an uncrewed version of Boeing’s human-rated CST-100 Starliner capsule from the competition, officials said Thursday.

SpaceX’s Dragon supply ship executed a laser-guided rendezvous with the International Space Station early Sunday, delivering an experimental expandable enclosure for attachment to the complex later this month for tests to verify the inflatable design’s suitability for future space habitats.

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.
