Live coverage: Space station crew home after 115-day mission

A powerful commercial communications satellite to broadcast Internet signals over the Asia-Pacific region has arrived at Cape Canaveral for final launch preparations ahead of a planned Dec. 15 liftoff on top of a SpaceX Falcon 9 rocket.

Five days after work to replace the grapple fitting on one end of the space station’s robot arm, commander Randy Bresnik and flight engineer Mark Vande Hei ventured back outside the lab complex Tuesday to lubricate the new arm mechanism, to replace a degraded camera and to carry out a variety of lower-priority chores.

Fully fueled for a flight to the International Space Station later this month, SpaceX transferred the Crew Dragon “Resilience” spaceship Thursday to a hangar near pad 39A at the Kennedy Space Center for attachment to its Falcon 9 launcher.
