Live coverage: SpaceX launches another batch of Starlink satellites

Watch as a Falcon 9 rocket lights its nine Merlin first-stage engines at pad 39A at the Kennedy Space Center in preparation for the 18th launch dedicated to SpaceX’s Starlink broadband satellite venture.

The United Launch Alliance Atlas 5 rocket, standing 191 feet tall and and weighing 720,000 pounds, unleashes 860,000 pounds of thrust from its main engine at 9:49:51 a.m. local time today to launch the secret NROL-79 payload for the U.S. National Reconnaissance Office from Vandenberg Air Force Base, California.

Weather forecasters will be on the lookout for rain showers and thunderstorms during Monday’s scheduled launch of a SpaceX cargo craft to the International Space Station, but there is a 60 percent chance conditions at Cape Canaveral will permit liftoff.
