Watch Ariane 5 launch with Star One D1 and JCSAT 15

The long queue of satellites waiting on launches aboard SpaceX’s Falcon rockets — a backlog the company says is worth $7 billion — will stay grounded while investigators determine what caused a Falcon 9 booster to disintegrate after liftoff Sunday.

A SpaceX Falcon 9 rocket lifted off from Cape Canaveral’s Complex 40 launch pad Tuesday at 12:33 a.m. EST (0533 GMT) with Hispasat 30W-6, a communications satellite to relay video and broadband signals between the Americas, Europe and North Africa.

Days after launching astronauts for the first time, SpaceX is set to resume a speedy cadence of satellite launches Wednesday night with liftoff of a Falcon 9 rocket carrying the company’s next batch of Starlink broadband relay stations.
