Live coverage: Japanese cargo craft arrives at space station

Astronauts Terry Virts and space station commander Barry “Butch” Wilmore ventured back outside Sunday for their third spacewalk in eight days to complete initial preparations for upcoming dockings by commercially developed Boeing and SpaceX crew ferry ships.

A Northrop Grumman Cygnus cargo ship arrived at the International Space Station on Monday, delivering nearly four tons of supplies and experiments to the research lab and its crew, including a $23 million titanium toilet and a high-definition virtual reality camera planned for use on a future spacewalk.

SpaceX launched a Falcon 9 rocket at 1:09 p.m. PDT (4:09 p.m. EDT) Wednesday from Vandenberg Space Force Base, California, on a mission hauling 51 more Starlink internet satellites into orbit.
