Live coverage: ULA launches Atlas 5 rocket with cargo for spysat agency

These photos show the enclosure of the Boeing-built Amos 17 commercial communications satellite, owned by the Tel Aviv-based operator Spacecom Ltd., ahead of liftoff aboard a SpaceX Falcon 9 rocket from Cape Canaveral.

SpaceX’s first Falcon Heavy rocket is set for liftoff Tuesday from NASA’s Kennedy Space Center in Florida, and the heavy-lift launcher will head on an easterly course over the Atlantic Ocean atop nearly 5 million pounds of thrust.

An unexpected reading from a ground sensor prompted SpaceX to scrub the planned launch of a Falcon 9 rocket Thursday with 60 more Starlink broadband satellites. It was the second last-minute abort of a rocket launch on Florida’s Space Coast in less than 10 hours, following a hold Wednesday night just before engines ignited on a United Launch Alliance Delta 4-Heavy rocket.
