The Falcon Heavy megarocket, the most powerful booster now in use, is set to launch the Arabsat-6A communications satelliteinto orbit from NASA's Kennedy Space Center in Florida today at 6:35 p.m. EDT (2235 GMT). With any luck, this will hopefully return SpaceX's East Coast landing zones (LZ-1 and LZ-2) to successful operations after an anomaly in December 2018 caused Falcon 9 B1051 to landing a mile or so offshore.
Elon Musk's private space company just revealed the first official image of the SpaceX Falcon Heavy Block 5 rocket, plus a timelapse video with the spacecraft.
SpaceX announced the delay on Twitter, saying: "Now targeting Falcon Heavy launch of Arabsat-6A on Wednesday, April 10 - weather forecast improves to 80 percent favorable".
The launch site for tomorrow's flight is Kennedy Space Center's Launch Complex 39A. Saudi Arabia's Arabsat is expecting its Lockheed Martin-built commercial communications satellite to stay in geostationary orbit for up to 15 years.
The satellite will enter into orbit tomorrow at a height of 22,000 miles (36,000km) above the Earth's equator. It was carrying Elon Musk's red Tesla Roadster with the crash dummy Starman at the wheel.
Sights and sounds from Dirk Nowitzki's final home game in Dallas
Dallas Mavericks forward Dirk Nowitzki (41) takes the court to face the Phoenix Suns at the American Airlines Center. The Mavericks will play their final game of the 2018-19 season against the Spurs on Wednesday night in San Antonio.
But more importantly, the launch will mark the second ever flight of the incredible Falcon Heavy launch system. It's also the Falcon Heavy's first commercial payload.
Wednesday's flight isn't an exact copy of last year's, however, as this vehicle will feature 10 percent more thrust - 5.1 million pounds from 27 Merlin engines - when compared to the February demonstration flight.
SpaceX Falcon Heavy has been rescheduled to Wednesday, April 10th 2019.
SpaceX also boasts the rocket can lift up to 64 metric tonnes into space, making it more powerful than a Boeing 737 jest full of cargo, crew and passengers. With three first-stage boosters akin to SpaceX's Falcon 9 rockets, the Falcon Heavy boosters, too, are created to fly back to Earth and be reusable.
The rocket company said: "Falcon Heavy draws upon the proven heritage and reliability of Falcon 9". Despite the satellite weighing no less than 6000 kg (13,200 lb), Falcon Heavy will still have enough latent performance to attempt the recovery of all three of its new Block 5 boosters. It's the first time a Block 5 booster will be used for the big rocket.
