Falcon Heavy launch delayed again, now targeted for Thursday evening

The Falcon Heavy is touted as the world's most powerful rocket "by a factor of two and will only be succeeded by NASA's Space Launch System (SLS) when completed".

The historic launch was watched by millions around the globe thanks to Mr Musk's body decision to mount a cherry-red Tesla sports vehicle as the rocket's payload.

After the launch, Falcon Heavy's center core made a successful vertical landing on the "Of Course I Still Love You" droneship in the Atlantic Ocean.

Eight minutes after takeoff, the spaceflight company landed the Falcon Heavy's side boosters at the company's two landing zones at Cape Canaveral Air Force Station in Florida.

The Falcon-Heavy rocket was launched at 22:35 (GMT) 11th April 2019, carrying Arabsat 6A satellite, manufactured by Lockheed Martin, to be placed in the exclusive orbit of Arabsat 30.5 degrees East. As the first commercial payload for Falcon Heavy, the launch opens a new era for the private space industry and expands SpaceX's dominance in the industry.

Mr Musk shared photos of the landing on Twitter, saying: "The Falcons have landed". By launching the used fairings on their own Starlink missions, SpaceX can effectively demonstrate the validity of this to future customers.

Musk's SpaceX, working to prove the flight-worthiness of its rocket fleet one mission at a time, aims to clinch one-third of all US National Security Space missions - coveted contracts that are worth billions of dollars.

Beyond that though, the Block 5 upgrades add almost 10 percent more thrust to Falcon Heavy compared with the demo mission previous year. The red Roaster - with a mannequin, dubbed Starman, likely still at the wheel - remains in a solar orbit stretching just past Mars.

Falcon Heavy Flight 2's evening launch window now sits at 8:00-8:32 pm ET (00:00-00:32 UTC), leaving little margin for any bugs prior to liftoff but still plenty of time for at least one serious attempt.

SpaceX plans to launch its next Falcon Heavy later this year on a mission for the U.S. Air Force.

Blasting off from the historic Pad 39A at NASA's Kennedy Space Centre at 4.05 am early this morning, the spacecraft deployed its Arabsat-6A satellite payload and successfully returned to Earth (it didn't blow up).

Until SpaceX came along, boosters were discarded in the ocean after satellite launches.
