A new photo from SpaceX highlights the immense power of the engines of a sleeping Falcon Heavy rocket. 

The next Falcon Heavy is scheduled to launch the Jupiter 3/EchoStar 24 mission on Wednesday (July 26), during which it will carry the world's largest private communications satellite to a geostationary orbit.

Ahead of the launch, SpaceX has joined the rocket's three boosters together in the company's hangar at Launch Complex-39A (LC-39A), at NASA's Kennedy Space Center, in Florida. SpaceX posted a photo to their Twitter account, which features a close-up of the 27 Merlin rocket engines mounted at Falcon Heavy's business end.

Combined, Falcon Heavy's engines are capable or producing over 5 million pounds force (22,241 kilonewtons) of thrust at liftoff, and can launch almost 60 thousand pounds (27,215 kilograms) to geosynchronous orbit. 

Depending on mission parameters, Falcon Heavy is designed for full reuse, but launches with the option for booster expandability in the event a payload's mass or orbital specifications require the rocket expel more fuel than required for its safe return.

For the Jupiter 3/EchoStar 24 mission, the rocket's two side boosters are expected to perform boost-back burns to return to SpaceX's Landing Zones 1 and 2 at Cape Canaveral, approximately 8 or 9 minutes after launch. 

The core booster, however, will not attempt a sea landing on one of SpaceX's autonomous drone ships, as is typical for Falcon 9 and Falcon Heavy launches. Instead, the core stage will use its fuel reserves to place the hefty Jupiter 3 in its proper orbit.

Maxar's new Jupiter 3 relay is the company's largest communication satellite ever. It will join others in the Hughes Jupiter fleet to provide internet and other broadband services to North and South America. Once in orbit, Jupiter 3 is expected to double the fleet's existing bandwidth capabilities. 

Falcon Heavy is expected to liftoff with Jupiter 3/EchoStar 24 at 11:04 p.m. EDT (1504 GMT) on Wednesday, July 26, from LC-39A at NASA's Kennedy Space Center.
