SpaceX’s fifth Falcon 9 launch in a little more than three weeks delivered 52 more Starlink internet satellites and two small hitchhiker payloads to orbit after a booming blastoff from the Kennedy Space Center in Florida on Saturday evening.

As expected, NASA announced Wednesday that the first unpiloted test flight of a SpaceX Falcon 9 rocket and a Crew Dragon astronaut ferry ship has slipped from later this month to March 2. The first unpiloted flight of Boeing’s Starliner capsule is now targeted for the April timeframe.

A Chinese environmental research craft and an experimental Earth-imaging nanosatellite successfully launched Saturday aboard a Long March 2D rocket.
