No, they do not.
The side booster rockets used to launch the space shuttle, for example, use solid fuel.
It uses fuel which is in the liquid state.
Robert Goddard was the first to use liquid fuel in a rocket
Most rockets use liquid oxygen (LOX) as an oxidizer to burn fuel, such as liquid hydrogen or kerosene. This combination creates a chemical reaction that produces thrust to propel the rocket.
The two types of rocket fuel are liquid fuel and solid fuel. Liquid fuel rockets use a combination of liquid propellants, such as liquid oxygen and liquid hydrogen, that are mixed and burned to create thrust. Solid fuel rockets have a solid mixture of fuel and oxidizer that is ignited to produce thrust.
Robert Goddard became the first person ever to use liquid fuel in a rocket.
The Saturn V rocket used a combination of liquid oxygen and RP-1, a refined form of kerosene, as fuel. These propellants were used in the first stage of the rocket to provide the thrust needed for liftoff.
Robert Goddard became the first person ever to use liquid fuel in a rocket.
500,000 gallons of cold liquid oxygen and liquid hydrogen
Rockets primarily use liquid hydrogen and liquid oxygen as fuel. These are combined in the rocket's engines to produce thrust by undergoing a chemical reaction and creating high-pressure gases that are expelled through a nozzle to propel the rocket forward.
Space shuttles use fuel when taking off and for control while in orbit, deorbiting, and landing. The main takeoff engines use liquid hydrogen and liquid oxygen, and there are two solid-fuel rocket boosters. In orbit, the shuttle uses thrusters that burn hydrazine and nitrogen tetroxide.
Rockets may use liquid nitrogen as a coolant or pressurant in the propulsion systems to maintain the temperature of the rocket components or provide pressure for fuel and oxidizer feed systems. Its low temperature and inert properties make it a suitable choice for certain rocket applications.
There are several types of rocket motors, including solid rocket motors, liquid rocket engines, and hybrid rocket engines. Solid rocket motors use a solid propellant that burns uniformly, providing thrust until the fuel is consumed. Liquid rocket engines utilize liquid fuel and oxidizer, allowing for adjustable thrust and the ability to shut down and restart. Hybrid rocket engines combine aspects of both, using a solid fuel and a liquid oxidizer, offering some advantages in performance and safety.
