Originally expected to take off Saturday, the launch of SpaceX’s first operational Crew Dragon mission was delayed to Sunday because of expected high winds at the Kennedy Space Center and weather off-shore where the Falcon 9 rocket’s first stage will attempt to land on a SpaceX droneship. The company plans to re-use the booster for the next Crew Dragon flight.

Russia lofted a military satellite Thursday to join a network of orbiting early warning stations detecting and tracking missile launches around the world, providing the Russian government notice of potential attack.

The SpaceX Dragon cargo ship loaded with supplies, crew provisions, new science experiments and an experimental expandable module for the International Space Station arrived Sunday morning for rendezvous, capture and berthing.
