What You'll Learn
The Falcon 9 carries 39,000 gallons of liquid oxygen
The Falcon 9 is a partially reusable, two-stage-to-orbit, medium-lift launch vehicle designed and manufactured by SpaceX. The rocket has two stages: the first (booster) stage carries the second stage and payload to a predetermined speed and altitude, and the second stage accelerates the payload to its target orbit. The Falcon 9 has completed 509 successful launches, with two in-flight failures, one partial failure, and one pre-flight destruction. It is the most-launched American orbital rocket in history.
The Falcon 9's fuel system has undergone several iterations of development. In 2011, SpaceX began a formal development program for a reusable Falcon 9, with a focus on the first stage. The V1.1 version of the rocket is 60% heavier with 60% more thrust than V1.0, with longer fuel tanks and more powerful engines.
The reliability and high launch cadence of the Falcon 9 have been noted, with the rocket becoming the first commercial rocket to launch humans into orbit in 2020. The rocket's first launch was on June 4, 2010, and its first commercial resupply mission to the International Space Station (ISS) was on October 8, 2012.

It also carries 25,000 gallons of rocket-grade kerosene
The Falcon 9 rocket, designed and manufactured by SpaceX, carries about 25,000 gallons of rocket-grade kerosene, or RP-1, as part of its fuel mixture. This type of kerosene is specifically designed for use in rocket engines and is known for its high energy density and ability to burn efficiently at high altitudes.
The Falcon 9's fuel mixture also includes approximately 39,000 gallons of cryogenic liquid oxygen, bringing the total fuel mixture to around 64,000 gallons. This mixture is crucial for the rocket's performance and enables it to achieve the necessary thrust for space missions.
The kerosene in the Falcon 9's fuel plays a vital role in the rocket's operation. When ignited, the kerosene combines with the liquid oxygen, resulting in a powerful combustion process that generates a significant amount of thrust. This thrust propels the rocket forward, enabling it to overcome Earth's gravity and achieve the incredible speeds necessary for space travel.
The 25,000 gallons of rocket-grade kerosene carried by the Falcon 9 contribute significantly to the rocket's overall performance and capabilities. This fuel is carefully chosen for its specific properties, ensuring that the rocket has the necessary energy and power to carry out its missions successfully.
The Falcon 9 rocket's fuel system, including the 25,000 gallons of rocket-grade kerosene, has been designed and optimized by SpaceX to meet the demands of space exploration. The fuel mixture ratio of RP-1 and liquid oxygen is carefully calibrated to balance efficiency, power, and reliability, showcasing the innovative engineering that has made SpaceX a leader in the aerospace industry.

The Falcon 9 burns 3,200 lbs of fuel per second
The Falcon 9 rocket is a partially reusable, two-stage-to-orbit, medium-lift launch vehicle designed and manufactured by SpaceX, an American aerospace company founded in 2002 with the goal of revolutionising space technology. The Falcon 9 rocket has had a successful track record, with 509 successful launches, two in-flight failures, one partial failure, and one pre-flight destruction. It is also the most-launched American orbital rocket in history.
The Falcon 9 rocket's first launch took place on June 4, 2010, and its first commercial resupply mission to the International Space Station (ISS) was on October 8, 2012. In 2020, it became the first commercial rocket to launch humans into orbit. The rocket has two stages: the first stage, or booster, propels the second stage and payload to a predetermined speed and altitude, while the second stage accelerates the payload to its target orbit.
The Falcon 9 rocket's impressive capabilities are due in part to its fuel efficiency. According to calculations, the Falcon 9 burns an astonishing 3,200 lbs of fuel per second when operating at full power. This fuel consumption rate is achieved through the use of nine engines, each contributing to the overall thrust and performance of the rocket.
To break down the fuel composition, the Falcon 9 carries approximately 39,000 gallons of cryogenic liquid oxygen and about 25,000 gallons of rocket-grade kerosene. This results in a total of 64,000 gallons of fuel mixture. With this fuel load, the Falcon 9 is able to achieve a sea-level thrust of 5,885 kN (1,323,000 lbf) at liftoff, with the engines burning for a nominal 180 seconds.
In summary, the Falcon 9 rocket's ability to burn 3,200 lbs of fuel per second is a testament to its engineering and design, enabling it to carry significant payloads and achieve successful missions.

The Falcon 9 is less fuel-efficient than a BMW M5
The Falcon 9 rocket, designed and manufactured by SpaceX, has been noted for its reliability and high launch cadence. It is a partially reusable, two-stage-to-orbit, medium-lift launch vehicle. The rocket has two stages: the first stage, or booster, carries the second stage and payload to a predetermined speed and altitude, and the second stage accelerates the payload to its target orbit.
The Falcon 9 uses a fuel mixture of liquid oxygen and rocket-grade kerosene. It carries approximately 39,000 gallons of liquid oxygen and 25,000 gallons of rocket-grade kerosene, for a total of 64,000 gallons of fuel mixture. At full power, the Falcon 9 burns through 3,200 lbs of fuel per second, with a fuel mixture ratio of 39% kerosene and 61% liquid oxygen.
Now, let's compare the fuel efficiency of the Falcon 9 to that of a BMW M5. The BMW M5 has a fuel efficiency of 21 miles per gallon on the highway and 15 miles per gallon in the city. On the other hand, the Falcon 9's first stage is estimated to be much less efficient than the BMW M5, with a fuel efficiency of 150 gallons per mile, or 35 feet per gallon. The second stage of the Falcon 9 is more fuel-efficient than the first stage, achieving 507 feet per gallon.
Considering the average fuel efficiency of both stages of the Falcon 9, it is estimated at 80.56 miles per gallon, which is higher than the BMW M5's fuel efficiency. However, when comparing the first stage of the Falcon 9 to the BMW M5, the rocket is less fuel-efficient. Therefore, it is accurate to conclude that while the Falcon 9 as a whole may have a higher average fuel efficiency than the BMW M5, its first stage operates with a lower fuel efficiency than the car.

The Falcon Heavy was designed with a propellant crossfeed capability
The Falcon Heavy rocket was designed and manufactured by the American aerospace company SpaceX. It is a super heavy-lift launch vehicle with partial reusability that can carry cargo into Earth orbit and beyond. The rocket consists of a center core with two Falcon 9 boosters attached and a second stage on top of the center core.
The Falcon Heavy was originally designed with a "propellant crossfeed" capability, which would allow the center core engines to be supplied with fuel and oxidizer from the two side cores until their separation. This approach was previously proposed by Vladimir Chelomei for the UR-700 launch system. By operating all engines at full thrust from launch, with fuel supplied mainly by the side boosters, the side boosters would be depleted sooner, allowing their earlier separation to reduce the mass being accelerated. This would leave most of the center core propellant available after booster separation.
However, in 2016, Musk stated that crossfeed would not be implemented. Instead, the center booster throttles down shortly after liftoff to conserve fuel and resumes full thrust after the side boosters have separated. This strategy ensures that after stage separation, around a third to half of the propellant remains in the center core.
The Falcon Heavy rocket has a high payload capacity, ranking second among currently operational launch vehicles. It can carry 8 t (18,000 lb) to a geostationary transfer orbit (GTO) with recovery of all three first-stage cores, or 26.7 t (59,000 lb) in fully expendable mode. The rocket's first test flight was conducted on February 6, 2018, carrying a Tesla Roadster belonging to SpaceX founder Elon Musk as a dummy payload.
