Four astronauts flying on SpaceX’s Crew Dragon “Resilience” spacecraft reached the International Space Station late Monday, one day after launching from the Kennedy Space Center in Florida. The capsule autonomously docked with the space station at 11:01 p.m. EST Monday (0401 GMT Tuesday).

United Launch Alliance early Thursday delayed the launch of a triple-core Delta 4-Heavy rocket — the largest launcher in the company’s fleet — until Saturday to allow engineers more time to resolve an issue with a ground pneumatics control system.

In preparation for liftoff Dec. 18 aboard a United Launch Alliance Atlas 5 rocket, the powerful Internet-from-space broadcasting satellite called EchoStar 19 was encapsulated in the nose cone.
