Watch live: Vice President Pence visits Kennedy Space Center

SpaceX’s second Falcon Heavy, outfitted to produce more thrust than the heavy-lifter’s debut flight last year, was raised vertical at launch pad 39A in Florida on Wednesday ahead of a launch attempt with the Arabsat 6A communications satellite.

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.

NASA announced Tuesday it has awarded SpaceX a $331 million contract to launch the first two pieces of the Gateway lunar outpost in 2024 using a modified version of the Falcon Heavy rocket to hurl the massive core of the deep space station toward the moon.
