On February 6, 2018, Elon Musk and his SpaceX team launched the Falcon Heavy rocket, with Musk's personal Tesla Roadster as the payload. The launch was a huge success, with the rocket generating 5 million pounds of thrust at liftoff. While the exact amount of fuel used is unknown, SpaceX uses a highly refined type of kerosene (RP-1) and liquid oxygen (LOX) for combustion. The Roadster, with its electric motor powered by lithium-ion cells, achieved 245 miles (394 km) on a single charge, showcasing the potential of electric vehicles.

The Falcon Heavy generated 5 million pounds of thrust at liftoff
The Falcon Heavy's maiden launch took place on February 6, 2018, from Launch Pad 39A at NASA's Kennedy Space Center in Florida. The rocket carried a Tesla Roadster belonging to SpaceX founder Elon Musk, with a mannequin dubbed "Starman" in the driver's seat. The Tesla was launched into a heliocentric orbit, with its farthest point past the orbit of Mars.
SpaceX uses a highly refined type of kerosene (also known as RP-1) and liquid oxygen (LOX) for combustion when fuelling its rockets. The Falcon Heavy has flown four missions since its demonstration flight, launching payloads for commercial customers and the U.S. government.
The success of the Falcon Heavy's maiden launch marked a significant accomplishment for a private sector company and captured the world's attention and imagination. With its powerful capabilities and reusability, the Falcon Heavy has become a sought-after launch vehicle for both commercial and government missions, including NASA's Psyche spacecraft mission to explore the metal-rich asteroid of the same name.

SpaceX uses a highly refined type of kerosene (RP-1)
SpaceX's launch of Elon Musk's personal Tesla Roadster into space was a highly publicised event. The payload was projected to travel 400,000 million kilometres (almost 250,000 million miles) away from Earth, at 11 kilometres per second (almost 7 miles per second). To achieve this, the Falcon Heavy generated 5 million pounds of thrust at liftoff.
RP-1 is manufactured with tighter density and volatility ranges and has significantly lower sulfur, olefin, and aromatic content. This is because sulfur and sulfur compounds attack metals at high temperatures, and even very small amounts can assist polymerization, hardening seals and tubing. RP-1 also has low levels of alkenes and aromatics, making it less toxic than jet and diesel fuels.
RP-1 was developed in the 1950s and has several advantages over other rocket fuels. It can be stored at ambient temperatures and has a lower explosion risk. Its higher density results in greater energy density. RP-1 is widely used globally, although in Russia and other former Soviet countries, the primary rocket kerosene formulations are T-1 and RG-1, which have slightly higher densities.
SpaceX has developed two kerosene-based engines, the Merlin 1 and Kestrel, and has discussed plans for a larger concept engine, the Merlin 2. The Merlin 1 powered the first stage of the Falcon 1 launch vehicle and is used on the Falcon 9 and Falcon Heavy launch vehicles. The Falcon 1's second stage was powered by a Kestrel engine.

The rocket also used liquid oxygen (LOX) for combustion
SpaceX, led by engineer Tom Mueller, developed a variety of liquid-propellant rocket engines in its first ten years. SpaceX uses a highly refined type of kerosene (also known as RP-1) as fuel for its rockets because of its high energy per gallon. Additionally, liquid oxygen (LOX) is required for combustion.
LOX has been used in rocket engines since the early days of space exploration. For example, NASA scientists have used liquid hydrocarbons and liquid oxygen for the first stage of Saturn vehicle launches and liquid hydrogen and liquid oxygen for the second stage.
LOX is also used in SpaceX's Merlin and Kestrel rocket engines, which power the Falcon 1, Falcon 9, and Falcon Heavy launch vehicles. The Falcon Heavy, which launched the Tesla Roadster into space, generated 5 million pounds of thrust at liftoff. This was made possible by the use of LOX as the oxidizer in the combustion process.
LOX is a key component of the Raptor family of rocket engines developed by SpaceX. Raptor engines are designed for deep cryogenic propellants, and LOX is used to cool the engines to near-freezing points. This increases the density of the propellant, resulting in improved engine performance. Raptor engines are also designed for extreme reliability and are being created for reuse with little maintenance.
In conclusion, liquid oxygen played a crucial role in the successful launch of the Tesla Roadster by enabling combustion and providing the necessary thrust to achieve the desired trajectory and distance from Earth.

The payload (Starman's Tesla Roadster) will travel 400,000 million kilometres
The payload of the Falcon Heavy rocket, which included the Starman mannequin and Elon Musk's personal Tesla Roadster, was launched on February 6, 2018. The car was painted cherry red to symbolise the launch's step towards reaching Mars. The payload travelled at a speed of 11 kilometres per second (almost 7 miles per second) and was expected to cover a distance of 400,000 million kilometres (almost 250,000 million miles) from Earth.
The Tesla Roadster became an artificial satellite of the Sun, completing its first orbit in 2019. It travelled beyond the orbit of Mars, reaching a maximum distance of 1.66 astronomical units (au) or 248,892,559 km (1.664 au) from the Sun. This distance is equivalent to almost 800 million miles or 766 million miles, according to different sources.
The car was mounted on the rocket's second stage and launched on an escape trajectory, entering an elliptical heliocentric orbit that crosses the orbit of Mars. This trajectory was designed so that the car would neither fly by Mars nor enter its orbit. The upper stage carrying the car was not equipped with the necessary propellant, manoeuvring, and communication capabilities to achieve a Mars orbit.
The Tesla Roadster is expected to remain in orbit for hundreds of millions or even billions of years. This extended duration is due to the high energy of the rocket fuel used, a highly refined type of kerosene (RP-1), combined with liquid oxygen (LOX) for combustion. The Falcon Heavy rocket generated 5 million pounds of thrust at liftoff, making it the most powerful liftoff since NASA's Saturn V.

The car will orbit for hundreds of millions, or billions, of years
On February 6, 2018, Elon Musk's SpaceX team successfully launched the Falcon Heavy rocket. Musk's personal "midnight cherry" Tesla Roadster was attached to the rocket as a payload. The Roadster is the first standard roadworthy vehicle sent into space. The launch was live-streamed, with footage showing the Roadster at various angles with Earth in the background.
The Falcon Heavy generated 5 million pounds of thrust at liftoff, making it the most powerful liftoff since NASA's Saturn V. SpaceX uses a highly refined type of kerosene (RP-1) and liquid oxygen (LOX) for combustion when fueling its rockets.
The Roadster is in a heliocentric orbit that crosses the orbit of Mars and reaches a distance of 1.66 astronomical units from the Sun. It will have close encounters with Earth, Venus, and Mars, and its orbit will change slightly during each encounter. Researchers specializing in orbital dynamics have analyzed the car's orbit for the next few million years. While it is impossible to map out precisely, there is a small chance that the Roadster could eventually return and crash into Earth or another planet.
The car will orbit for hundreds of millions, or even billions, of years. Over a million years, the Tesla has a 6% probability of colliding with Earth and a 2.5% chance of colliding with Venus. After 3 million years, the odds of an Earth collision increase to 10%. In the longer term, the Roadster is estimated to have a 50% chance of lasting a few tens of millions of years. It is unclear whether it will end its journey as debris on a planetary surface or as a ball of metal plunging into the Sun.
