The Falcon Heavy is the most powerful rocket in the world today. The launch has already been delayed and had been originally anticipated for earlier this week.
At the end of the month, on April 25, SpaceX is also expected to launch their regular Falcon 9 rocket and Dragon cargo capsule for their 17 supply mission to the International Space Station. After liftoff, the huge rocket's two side boosters and central core stage are expected to return to Earth for the triple landing. The company said the latest chance for the launch is 8:32 p.m. Delays or postponements can happen because of weather, technical problems or other issues.
Standing 250 feet tall, Falcon Heavy flies with three rocket boosters. The Falcon Heavy Launch will be streamed live on SpaceX's webcast page approximately 20 minutes before liftoff.

In addition to Wednesday's launch, SpaceX will attempt to land Falcon Heavy's side boosters at Landing Zones 1 and 2 while Falcon Heavy's center core will attempt to land on "Of Course I Still Love You" droneship during the Arabsat-6A mission. We'll see if they have better luck this time around.
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). It was built to serve as SpaceX's heavy lift vehicle, with five million pounds of thrust capable of putting even large payloads into Earth orbit and beyond.
"Now targeting Falcon Heavy launch of Arabsat-6A on Wednesday, April 10 - weather forecast improves to 80% favorable", SpaceX tweeted in an update on 9 April. A Falcon Heavy will launch the STP-2 mission for the U.S. Air Force. A standard Falcon Heavy launch costs $90 million, according to the company's website, compared to $62 million for the Falcon 9. On that flight, the Falcon Heavy launched a red Tesla Roadster owned by SpaceX founder Elon Musk and stuck two of its three first-stage booster landings. The main booster, however, missed landing on one of SpaceX's seaborne landing platforms and instead splashed into the ocean.
SpaceX's payload for this mission is a high-capacity telecommunications satellite known as Arabsat-6A, which will deliver radio, Internet, television and mobile access to customers in the Middle East, Africa and Europe.
