On SpaceX's current manifest, there are 10 more Falcon Heavy missions between now and the end of 2024. In truth, there is a reasonable amount of demand for a large rocket like the Falcon Heavy.

NASA's Psyche Asteroid mission was supposed to fly in September but was also delayed after the payload was not ready. Another Space Force mission on the Falcon Heavy, USSF-52, was originally supposed to fly in October 2021. The USSF-44 mission was originally scheduled for December 2020. Of late, the problem has been delayed payloads. That does not mean there is 100 times the demand for the Falcon 9, but it suggests that by continuing to improve the performance of the single-core Falcon rocket, SpaceX eroded some of the potential market for Falcon Heavy when it was designed about a decade ago. To put the demand for Falcon Heavy into perspective, in the 40 months since the last heavy launch, SpaceX has flown the Falcon 9 rocket 111 times. It's just that, well, there has not been an overwhelming desire. There are other structural adaptations, but basically, SpaceX could manufacture (and reuse hardware) for just about as many Falcon Heavy rockets as the market desires. At its essence, the Falcon Heavy consists of a core stage that is a modified version of a Falcon 9 rocket's first stage, and two side-mounted boosters that are somewhat less modified. The long gap between flights has not occurred due to a shortage of Falcon Heavy rockets. This will provide a good test of the upper stage's ability to perform for an extended period.

What we do know is that this mission will require the Falcon Heavy's upper stage to operate for a far longer period than usual, with about six hours between the initial firing of its Merlin vacuum engine and a final firing. Maybe you could mix in a few more inscrutable acronyms next time. In an emailed news release discussing the launch, Space Force was not particularly helpful with its description of the satellites: 'The Long Duration Propulsive EELV Secondary Payload Adapter (LDPE ESPA)-2 and Shepherd Demonstration will carry a variety of payloads that will promote and accelerate the advancement of space technology for the benefit of future Programs of Record.' Advertisement The secondary payload is a small satellite called Tetra-1, which is a prototype for a kind of satellite the US military hopes to fly one day in geostationary orbit-to do something. Not much is known about the two spacecraft launching on this mission for Space Force. In this case, however, Falcon Heavy's first and second stages will be doing all the work. Typically such payloads are injected into a transfer orbit, and then the spacecraft's onboard propellant is used to raise the vehicle to a circular geostationary orbit. This will be SpaceX's first 'direct-to-GEO' mission, which means the powerful Falcon Heavy rocket will launch its payload directly into a geostationary orbit nearly 36,000 km above the Earth's surface. And perhaps more importantly, does this suggest that the Falcon Heavy-developed internally at SpaceX, at the company's own expense, for half a billion dollars-was a mistake?īut first, some details about the launch, which is set for 9:41 am ET (13:41) on Tuesday from Kennedy Space Center, in Florida. Under the power of 27 Merlin engines in its first stage, the rocket will carry two space technology payloads into orbit for US Space Force.Īhead of this much-awaited USSF-44 launch, it is natural to ask why it has been more than 40 months since the rocket last flew. As early as Tuesday morning, the Falcon Heavy will take flight for the first time since June 2019, ending a long period of inactivity for the world's most powerful, operational rocket.
