According to SpaceX, Falcon Heavy is "the most powerful operational rocked in the world by a factor of two", with its 27 Merlin combustion engines capable of generating more than 5 million pounds of thrust at lift-off. The satellite will be deployed about 34 minutes after launch, but it's those first 34 minutes that will be of most interest to space enthusiasts.
SpaceX issued a warning that Space Coast residents should expect several loud sonic booms as the rockets arrive back on Earth.
SpaceX has two operational rockets: the Falcon 9, which with 21 launches in 2018 dominates the U.S. market, and the Falcon Heavy, which as its name suggests is created to lift much heavier payloads into more distant orbits.
Falcon Heavy has already been chosen for a few contracts, including a $130 million contract to launch an Air Force satellite that was awarded just four months after its inaugural flight in February 2018.
As with the first launch of the Falcon Heavy, SpaceX will try to safely land the two side rocket boosters back at Cape Canaveral Landing Zones 1 and 2 in Florida. Now, all eyes will be on Wednesday's launch to see if SpaceX can successfully land those boosters and core-and prove its business model. Featuring three brand new Block 5 boosters, this mission also has the potential to redeem a slight anomaly that caused Falcon Heavy Flight 1's center core to be destroyed during a recovery attempt.
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. SpaceX's Falcon Heavy will launch the Arabsat-6A satellite from Launch Complex 39Z (LC-39Z) at NASA's Kennedy Space Center in Florida.
Though Falcon Heavy's inaugural launch ultimately went off without a hitch, SpaceX will now have to repeat that success with the added risk of carrying a multimillion dollar satellite.

More recently, the Falcon Heavy rocket has entered the conversation for human exploration. But before that can happen, plenty more work needs to be done. Even with SpaceX boss Elon Musk doing his best to keep expectations low, it was a monumental event and luckily the entire thing went off without a hitch. Then again, that's no different from every other launch.
