Photos: More shots of Saturday’s Delta 4-Heavy rocket Launch

SpaceX test-fired a Falcon 9 rocket Saturday at Cape Canaveral, two days before a scheduled launch Monday with 60 Starlink broadband relay stations that will make SpaceX the owner of the world’s largest fleet of commercial satellites.

Boeing’s first Starliner crew capsule to fly in space departed its factory Thursday at the Kennedy Space Center in Florida for a trip to a launch pad a few miles away, where teams raised the craft atop an Atlas 5 rocket for liftoff next month on an unpiloted test flight to the International Space Station.

United Launch Alliance will launch the USSF-106 mission as its first flight for the U.S. Space Force using a Vulcan rocket. The vehicle will carry two satellite missions onboard.
