Update as of April 26, 11:40 am EDT: SpaceX is now aiming to launch its sixth Falcon Heavy mission on Thursday, April 27, carrying satellites for Astranis and ViaSat.
SpaceX’s mighty Falcon Heavy rocket will launch for the sixth time on Thursday (April 27), and you can watch the action live.
Falcon Heavy is scheduled to lift off from NASA’s Kennedy Space Center in Florida at 7:29 p.m. EDT (2329 GMT) carrying two satellites into high-Earth orbit.

The primary payload for today’s mission is ViaSat-3 Americas, a 14,000-pound (6,400-kilogram) broadband satellite operated by California-based company Viasat.
The second satellite flying today is Arcturus, a communications spacecraft operated by San Francisco-based Astronis Space Technologies.

Falcon Heavy consists of three built first stages of SpaceX’s workhorse Falcon 9 rocket. The central booster is topped by the upper stage and payload(s).
Falcon Heavy debuted in February 2018 with a memorable test flight that sent SpaceX founder and CEO Elon Musk’s red Tesla Roadster into orbit around the sun with Starman, a spacesuited mannequin, at the wheel.
The Burley rocket has since flown four times, most recently in January of this year, when it launched a classified USSF-67 mission for the US Space Force.
Falcon Heavy’s three first-stage boosters are designed to be reusable. However, none of the boosters will be recovered on today’s mission because there won’t be enough fuel left to safely return to Earth for vertical touchdown.
For more than five years, the Falcon Heavy was SpaceX’s most powerful rocket. But the company’s gigantic Starship vehicle took that title with its first liftoff on April 20, a test flight that reached a maximum altitude of 24 miles (39 kilometers) and ended in an ordered explosion above the Gulf of Mexico for safety.
Starship’s 33 first-stage Raptor engines generate 16.7 million pounds of thrust at liftoff, According to SpaceX (opens in new tab). That’s more than three times what the Falcon Heavy produces, and almost twice as much as the second-place vehicle, NASA’s Space Launch System megarocket.
Editor’s note: This story has been corrected to say that Starship produces 16.7 million pounds (not tons) of thrust at liftoff.
