Video: Falcon 9 launch of DSCOVR

After a six-week delay for undisclosed reasons, SpaceX raised a Falcon 9 vertical on its launch pad Thursday at the Kennedy Space Center in Florida for another try early Friday to send into orbit the company’s next batch of Starlink Internet relay stations and a pair of commercial BlackSky Earth-imaging microsatellites.

Breaking a SpaceX record for the shortest span between two missions from the same launch pad, a Falcon 9 rocket lifted off Saturday from Cape Canaveral carrying 58 more Starlink broadband satellites and three Earth-imaging spacecraft for Planet.

A decade in the making, the core stage for NASA’s first Space Launch System heavy-lift rocket rolled into the Vehicle Assembly Building at the Kennedy Space Center Thursday to join up with twin solid rocket boosters and an Orion capsule for an unpiloted test flight around the moon.
