It weighs 470 kg and the latest variant has a thrust of 845 kN at sea level (981 kN in vacuum for the vacuum engine variant). Merlin 1D has the highest thrust-to-weight ratio (TWR) of all rocket engines in the world. Falcon Heavy uses the latest version called Merlin 1D – the rocket’s first stage consists of three cores, each equipped with 9 Merlin 1D engines, and the upper stage is propelled by a single Merlin 1D-Vac engine (a modified engine variant optimized for vacuum). Merlin has undergone many changes over the years and there have been several variations. SpaceX manufactures several hundred of these engines per year and is therefore also the world’s largest manufacturer of rocket engines. Merlin is an open combustion cycle rocket engine running on RP-1 (highly refined kerosene) and liquid oxygen.

In addition, FH is able to launch large payloads beyond Earth’s orbit.Īfter the successful Falcon Heavy demonstration mission in February 2018, Elon Musk revealed that the rocket cost at least half a billion dollars to develop. Falcon Heavy is powered by Merlin 1D engines and is the most powerful rocket currently in operation (it has the highest thrust and also the highest LEO payload capability). The idea behind Falcon Heavy is simple, it’s basically three Falcon 9 boosters assembled together (however, Elon Musk revealed during the SES-10 press conference that FH’s development was far more challenging than originally expected). The inaugural launch kept being postponed and Falcon Heavy finally launched for the first time in February 2018. In 2008, Falcon Heavy’s first launch was scheduled for 2013. Public first learned about FH back in 2005, a few years before Falcon 1’s first successful launch. Prior to STP-2, Falcon Heavy launched the Arabsat-6A communications satellite in April 2019 and Elon Musk’s Tesla Roadster in February 2018.Falcon Heavy (FH) is the most powerful member of SpaceX’s Falcon rocket family. Whenever Falcon Heavy flies next will mark the vehicle’s first launch since June 2019 when the rocket carried two dozen small satellites on a demonstration mission for the U.S. The Space Force has not disclosed payloads for USSF-52 or USSF-67. The only known payload to fly on USSF-44 is the TETRA-1 small satellite made by Millennium Space Systems. USSF-44 would be Falcon Heavy’s first national security direct-inject mission to geostationary orbit and SpaceX’s first mission to attempt a double droneship landing. Falcon Heavy rockets lift off from NASA’s Kennedy Space Center. No target launch dates have been announced yet although the Space Force said they would happen in 2022.

The Space Force missions USSF-44 and USSF-52 both were scheduled to fly in 2021 but have been delayed by payload readiness and range scheduling issues. The addition of a third national security mission for Falcon Heavy will make for quite a scheduling challenge for SpaceX’s three-core rocket that also is projected to launch in 2022 a Viasat-3 commercial broadband satellite with an Astranis communications satellite as a secondary payload, as well as NASA’s Psyche planetary science mission. The mission will fly on a Falcon Heavy rocket with an expendable center core, although SpaceX will be able to recover the two side boosters. Space Systems Command spokesman confirmed Oct. USSF-67, a classified national security mission to geostationary Earth orbit awarded to SpaceX last year under a $332 million contract, is “on track for mid-to-late 2022 launch,” a U.S. national security launch that will be added to the Falcon Heavy’s crowded 2022 manifest. Space Force missions on Falcon Heavy rockets that had been scheduled for 2021 have slipped into next year.
