Falcon Heavy

Two U.S. military satellites set to ride SpaceX’s Falcon Heavy rocket into geosynchronous orbit more than 22,000 miles above Earth were mated with their launch vehicle Friday at Kennedy Space Center ahead of a scheduled sunset launch this weekend.

Northrop Grumman and the U.S. Space Force say converted launch vehicle payload adapter rings, upgraded with power and propulsion to create full-fledged satellites, are proving effective in more rapidly delivering military instruments and sensors to orbit. Another such mission is set to launch on SpaceX’s next Falcon Heavy rocket.

SpaceX test-fired the 27 engines on its next Falcon Heavy rocket at 12:45 p.m. EST (1745 GMT) Tuesday in preparation for a launch later this week for the U.S. Space Force. The Falcon Heavy static fire occurred on pad 39A at Kennedy Space Center.

SpaceX is set to kick off a busy week of launch preparations at Kennedy Space Center for the first of five planned Falcon Heavy rocket missions this year, targeting a dusk departure no earlier than Friday evening from Launch Complex 39A on a flight for the U.S. Space Force.

The U.S. Space Force confirmed Tuesday that a Falcon Heavy launcher placed two main payloads and at least three smaller rideshare satellites directly into a high-altitude geosynchronous orbit after liftoff from Florida, an achievement that checks off one of the final unproven capabilities for SpaceX’s rocket family.

SpaceX’s Falcon Heavy, the world’s most powerful operational launch vehicle, lifted off from Kennedy Space Center in Florida at 9:41 a.m. EDT (1341 GMT) Tuesday on a mission to deliver two U.S. Space Force satellites and multiple rideshare payloads into geosynchronous orbit, a journey that will take about six hours for the rocket’s upper stage. The Falcon Heavy’s two side boosters successfully returned to Cape Canaveral for landing about eight minutes after liftoff.

The first Falcon Heavy rocket flight since 2019 is scheduled Tuesday to kick off SpaceX’s longest-duration launch mission to date, a roughly six-hour climb into geosynchronous orbit more than 20,000 miles over the equator with a bundle of payloads for the U.S. Space Force. The powerful rocket’s two reusable side boosters will return to Cape Canaveral for landing.

NASA says the Psyche mission, a robotic asteroid explorer that missed a launch opportunity this year due to software testing problems, has been rescheduled for liftoff from Florida in October 2023 on a SpaceX Falcon Heavy rocket.

SpaceX fired up 27 engines on a Falcon Heavy rocket Thursday night at Kennedy Space Center, sending a rumble across the spaceport in a hold-down test-firing before a launch next week for the U.S. Space Force.
