Watch conditions at Kennedy Space Center during Tropical Storm Isaias

SpaceX plans to launch its next group of Starlink broadband satellites aboard a Falcon 9 rocket as soon as Tuesday, Jan. 21, from Cape Canaveral, two days after the company is scheduled to launch a modified Falcon 9 booster from a separate facility at the Florida spaceport to test the Crew Dragon spaceship’s emergency escape system.

A Falcon 9 rocket powered by a first stage booster recovered after a launch in July is being readied for another flight Thursday from NASA’s Kennedy Space Center in Florida.

The Falcon Heavy rocket was lowered to the horizontal position before sunrise Friday morning after less than a day standing at the launch pad.
