The SpaceX design is also cheaper to operate than the Delta, with each Falcon launch costing between $90 and $150 million. The Falcon is then expected to deploy its payload-the Arabsat-6A communications satellite-approximately 34 minutes after launch.
Today's launch, which is scheduled for 6:35 p.m. EST, will see SpaceX use the Falcon Heavy in a commercial capacity for the very first time, sending a communications satellite from Arabsat into orbit around Earth. The first retrieval didn't go so well for the poor old core booster, which missed the landing and plunged into the ocean.
Media outlets in Central Florida report sonic booms could potentially be heard in Brevard, Orange, Seminole and Volusia counties. The side boosters will touch down at Cape Canaveral Air Force Station at SpaceX Landing Zones 1 and 2.
SpaceX just delayed the launch debut of Falcon Heavy Block 5 by about an hour and a half to dodge bad high-altitude wind conditions that would be a risk to the vehicle during launch and to both side boosters during their subsequent landing attempts.More news: Meghan and Harry 'move into Frogmore Cottage' ahead of royal baby's birth
All of SpaceX's rocket launches are streamed live online via the company's website and official YouTube page.
SpaceX has several paying customers committed to flying on Falcon Heavy, including Inmarsat, Viastat and Arabsat, according to its launch manifest. At the time, no one was quite sure how SpaceX would market the world's most powerful rocket, which did not seem to fit particularly well into any niche, especially after the company's own Falcon 9 rocket saw significant performance increases.
Forecasters with the U.S. Air Force 45th Space Wing are predicting an 80 percent chance of good launch conditions for the almost two-hour window.
The stakes were high when the Falcon Heavy lifted off for the first time in February 2018. SpaceX is expected to attempt to land all three this week.More news: Notre Dame’s repeat bid falls short on Ogunbowale’s miss
According to the US Air Force 45th Weather Squadron, which is responsible for forecasting the weather for space launches from Kennedy Space Center, there is an 80 per cent chance of favourable weather for this particular launch.
Tomorrow's SpaceX launch will carry a 6,000kg Saudi Arabian payload into orbit around Earth. The two side boosters will attempt their landings at SpaceX's Landing Zones 1 and 2 at Cape Canaveral in Florida, while the centre core will attempt to land on a droneship named Of Course I Still Love You, which is now stationed in the Atlantic Ocean.
This will be the first commercial mission for the Falcon Heavy. Falcon Heavy only has five missions on its manifest so far. Following a last-minute delay, SpaceX expects to launch the Arabsat-6A from NASA's historic Pad 39A this evening.More news: BJP makes $1.4trn infrastructure boost promise for election
