A simple rocket like you fire on the 4th of July is a solid propellent rocket. It is a tube filled with gunpowder that is attached to a stick. The Chinese invented these rockets back around ~1200 AD.
Three main types of rockets that power modern spacecrafts are liquid-propellant rockets, solid-propellant rockets, and hybrid rockets. Liquid-propellant rockets use liquid fuel and oxidizer, solid-propellant rockets use solid fuel and oxidizer mixed together, and hybrid rockets use a combination of solid and liquid propellants.

Liquid-propellant rockets use liquid fuel and liquid oxidizer as propellants, while solid-propellant rockets use a solid chemical mixture as propellant. Both types of rockets rely on these propellants to generate thrust for propulsion.

Solid-fuel rockets: These rockets use a solid propellant that is burned to create thrust. Liquid-fuel rockets: These rockets use liquid propellants, typically a fuel and an oxidizer, that are mixed and burned to produce thrust. Hybrid rockets: These rockets use a combination of solid and liquid propellants for propulsion. Ion propulsion rockets: These rockets use ionized gas accelerated by electromagnetic fields to generate thrust. Nuclear thermal rockets: These rockets use a nuclear reaction to heat a propellant, typically hydrogen, for propulsion.
Solid fuel rockets use a solid propellant mixture, which is more stable and easier to store compared to liquid fuel rockets that use liquid propellants. Iron rockets typically refer to solid fuel rockets using iron particles as part of the propellant mixture to enhance thrust. Overall, solid fuel rockets are simpler and more reliable but lack the efficiency and flexibility of liquid fuel rockets.
Rockets commonly run on liquid fuel, solid fuel, or a combination of both. Liquid fuel rockets use liquid oxygen and liquid hydrogen, while solid fuel rockets use a solid propellant mixture. Both types of rockets generate thrust through a controlled combustion process.
The Shuttle uses both. The outer rockets on the main body are aluminum oxide. Once lit you are on. In the big container sits a lot of separated liquid Oxygen and liquid Hydrogen. When mixed at the output nozzles, a steerable, controllable jet of very hot water is let go. The difference being solid rockets go on then off. The liquid ones are controllable.
Rockets typically use a variety of propellants, which can be broadly categorized into liquid and solid types. Liquid rockets often use a combination of liquid fuel (like liquid hydrogen or RP-1) and an oxidizer (such as liquid oxygen). Solid rockets utilize a preloaded mixture of fuel and oxidizer in a solid form. The choice of propellant depends on the mission requirements and rocket design.
No, a solid propellant rocket cannot be shut down and restarted once it has been ignited. Solid propellants burn continuously and cannot be controlled or interrupted once the combustion process begins. This is in contrast to liquid propellant rockets, which can be throttled, shut down, and restarted as needed.
The correct term is "solid propellant rocket". These are rockets that burn fuel that is not a liquid(or they are NOT liquid fuel rockets). These rockets have a fuel that is poured into the rocket case and turns to a solid. Once ignited, there is no stopping the burn or controlling it.A simple example of this is rocket you shoot on the 4th of July. It burns black powder that has been formed into a cardboard case.Whereas, a liquid fuel rocket can be controlled by varying the amount of fuel that is injected into the rocket motor.
