What You'll Learn
The Falcon Heavy's fuel cost is around $0.5 million
The Falcon Heavy is a powerful rocket developed by SpaceX, with a capacity of over 5 million pounds of thrust at liftoff. It is composed of three reusable Falcon 9 cores, each with nine Merlin engines, utilizing RP-1 (refined kerosene) and liquid oxygen as propellants. The cost of fueling a Falcon Heavy rocket is estimated to be around $0.5 million. This estimate is based on the assumption that the cost of fueling a Falcon 9 is around $200,000, as SpaceX does not publicly disclose fuel cost information.
The Falcon Heavy's fuel cost is a significant expense, but it's important to consider other factors that contribute to the overall cost of a launch. The initial engineering, manufacturing, and servicing between flights are also substantial expenses. Additionally, the environmental impact of the rocket's fuel, RP-1, and liquid oxygen, which produce a significant amount of carbon dioxide when burned, cannot be overlooked.
SpaceX has emphasized the reusability of the Falcon Heavy, which helps to reduce the resources required for each launch. The ability to recover and reuse the rocket boosters and main fuel tanks contributes to a massive reduction in launch costs. This reusability also sets it apart from previous spacecraft, such as the Space Shuttle, where the launch vehicles were not reusable, resulting in higher costs and environmental impact.
The Falcon Heavy's fuel efficiency is a critical aspect of its design. By utilizing a propellant crossfeed" capability, the center core engines receive fuel and oxidizer from the side cores until their separation. This approach optimizes fuel usage, allowing for the depletion of the side boosters and their earlier separation, thereby reducing the mass being accelerated. This efficiency enhances the rocket's performance and payload capacity.
The Falcon Heavy's fuel cost of around $0.5 million is a significant expense, but it is a small portion of the overall cost of a launch. The rocket's reusability and fuel efficiency contribute to cost savings and help to mitigate the environmental impact of each launch. With its powerful capabilities and innovative design, the Falcon Heavy represents a significant advancement in space exploration and payload delivery.

The fuel includes RP-1 and liquid oxygen
The Falcon Heavy is composed of three reusable Falcon 9 nine-engine cores with 27 Merlin engines that generate more than 5 million pounds of thrust at liftoff. The Falcon Heavy's first stage is equipped with 12 landing legs (4 on each booster) and 12 hypersonic grid fins, four on each booster, positioned at the base of the interstage or nosecone. The interstage is a composite structure that connects the center core on the first stage and second stages and holds the release and separation system.
The Falcon Heavy's first stage incorporates 27 Merlin engines across three aluminum-lithium alloy rocket cores containing liquid oxygen and rocket-grade kerosene (RP-1) propellant. The Merlin engine was originally designed for recovery and reuse. Merlin Vacuum features a larger exhaust section and a significantly larger expansion nozzle to maximize the engine’s efficiency in the vacuum of space. Its combustion chamber is regeneratively cooled, while the expansion nozzle is radiatively cooled.
The RP-1 fuel and liquid oxygen (LOX) oxidizer are loaded into the Falcon Heavy's tanks in a specific timeline. RP-1 fuel loading begins on both stages at T-0:35:00, and liquid oxygen oxidizer loading begins on stage 1 at the same time. At T-0:31:00, liquid oxygen oxidizer loading is finished on stage 1, and at T-0:16:00, liquid oxygen oxidizer loading begins on stage 2. At T-0:15:00, liquid oxygen oxidizer top-off begins on stage 1, and at T-0:05:20, RP-1 fuel loading is finished on stage 1. At T-0:02:40, liquid oxygen oxidizer is at flight levels on stage 1, and at T-0:02:05, liquid oxygen oxidizer is at flight levels on stage 2. At T-0:01:00, liquid oxygen top-off finishes, and at T-0:00:40, the tanks are pressurized for flight.
The cost of fueling a Falcon Heavy is estimated to be around $0.5 million for LOX and RP-1. LOX costs around $0.20/kg, so RP-1 would be approximately $1.20/kg.

The rocket is reusable, reducing resources and costs
The Falcon Heavy rocket, designed, manufactured, and launched by American aerospace company SpaceX, is a super heavy-lift launch vehicle with partial reusability. This reusability is a key feature of the rocket, reducing resources and costs.
SpaceX has expressed hopes that all rocket stages will eventually be reusable, and the company has successfully demonstrated routine land and sea recovery of the Falcon 9 first stage, which shares a design with Falcon Heavy. The Falcon Heavy first stage incorporates 12 landing legs (4 on each booster), which are stowed along the side of each booster and deploy just prior to landing. The rocket's descent is controlled by four retractable grid fins at the top of each of the three boosters, which extend after separation. The side boosters then land softly on the ground, and in fully reusable launches, the center core touches down on a drone ship.
The Falcon Heavy's reusability reduces costs by minimizing the resources required for each launch. The rocket's design, based on Falcon 9, minimizes stage separation events and maximizes reliability. The Merlin engines used in the Falcon Heavy were also designed for recovery and reuse, and the company is recovering fairings for reuse on future missions.
In addition to reducing resources and costs, the Falcon Heavy's reusability also contributes to its payload performance. When recovering all three booster cores, the geosynchronous transfer orbit (GTO) payload is 8 t (18,000 lb). However, if only the two outside cores are recovered while the center core is expended, the GTO payload increases to approximately 16 t (35,000 lb). This reusability allows the Falcon Heavy to achieve a higher payload capacity at a lower price compared to other rockets.

This incredible power allows the Falcon Heavy to lift nearly 64 metric tons (141,000 lbs) into orbit, including the weight of the rocket itself.
The Falcon Heavy's 27 engines are organised into three Falcon 9-derived cores, with nine engines in each core. These cores are fuelled by liquid oxygen and rocket-grade kerosene, also known as RP-1. RP-1 is a refined form of kerosene with a 34% carbon content, and its combustion produces a significant amount of carbon dioxide. While the environmental impact of a single Falcon Heavy launch is negligible compared to global industrial emissions, the planned frequency of SpaceX launches could make this a more significant issue.
The design of the Falcon Heavy is based on the Falcon 9, with improvements made to increase payload capacity and thrust. The Falcon Heavy's first stage is equipped with 12 landing legs and state-of-the-art hypersonic grid fins, which orient the rocket during re-entry. The second stage is powered by a single Merlin Vacuum Engine, which delivers the payload to orbit.
The Falcon Heavy is notable for its reusability, which reduces the resources required for each launch and lowers launch costs. This reusability is a significant advancement, as previous reusable spacecraft still required expendable launch vehicles. SpaceX has estimated the cost of the Falcon Heavy to be approximately US$1,300 per kg of payload, a significant reduction from the US$60,000 per kg cost of the space shuttle.
