Live coverage: Space station crew investigating slow pressure leak

SpaceX has postponed the launch of its next Falcon 9 rocket indefinitely. The rocket was originally scheduled take off Wednesday from pad 39A at NASA’s Kennedy Space Center in Florida with a top secret U.S. government payload named Zuma. A few minutes after launch, the Falcon 9’s first stage will return for a landing at nearby Cape Canaveral Air Force Station.

Sporting a new blue and white paint scheme to mark the upcoming 60th anniversary of the first human spaceflight, a Russian Soyuz rocket loaded with 38 international satellites has rolled out to its launch pad at the Baikonur Cosmodrome in Kazakhstan ahead of a planned liftoff Saturday.

Staging NASA’s third spacewalk in 15 days, two astronauts floated outside the International Space Station Friday and installed a new high definition camera, replaced a degraded camera on a recently attached robot arm grapple fixture, finished lubricating the mechanism and carried out a variety of other “get-ahead” tasks.
