Why liquid hydrogen cannot be used as a fuel?
Liquid hydrogen IS used as a fuel. It's used in rockets - and some cars.
Which fuel is used in rockets?
There are two three types of fuel used in rockets 1) Solid fuel - an aluminum powder used for an initial boost into space. 2) Liquid fuel - usually super-cold liquid hydrogen and oxygen is used is the Space Shuttle's main engines during launch. 3) Hypergolic fuel - Monomethylhydrazine and Nitrogen Tetroxide does not need a source of ignition. It is mainly used for maneuvering in space.
Can space rockets be stopped once ignited?
Depends on the type of fuel being used, solid rocket fuel can not be turn off, liquid fuel can.
Which fuel is used in spacecraft?
Spacecraft use either liquid or solid fuel. All rockets operate on a combination of a fuel and an oxidizer to help the fuel burn. Russian rockets use liquid fuel, a combination of Liquid Oxygen (also called LOX) and a highly refined form of kerosene (also called RP-1). American and other rockets and spacecraft use a combination of liquid fuel as above and solid fuel. Solid rocket fuel is composed of fuel like charcoal, metals such as alumnium or zinc, or even sugar along with potassium nitrate as an oxidizer all combined in a binder such as rubber or forms of plastics. An additive such as sulfur can also be added to help stabilize the burn. Once in orbit, hypergolic fuels are used. 2 chemicals are used which, when combined explode. This allows rockets to be used without any ignition source.
What is the fuel in rockets?
Liquid oxygen and liquid hydrogen are used as the propellant in the high efficiency main engines of the Space Shuttle. LOX/LH2 also powered the upper stages of the Saturn V and Saturn 1B rockets. Another cryogenic fuel with desirable properties for space propulsion systems is liquid methane.
Why liquid hydrogen cannot be used as a fuel?

What Rockets are used by astronauts today?
Both liquid and solid fuel rockets are used for manned flight today.
Which rocket is older solid fuel rockets or liquid fuel rockets?
The earliest rockets--i.e., those built by the Chinese as early as the 14 century--used solid fuel.
What are V-2 rockets?
The second of Germany's Vengeance Weapons. The first Liquid Fuel Ballistic Missile to be used in war.
How can you use oxygen in rockets?
Liquid oxygen and liquid hydrogen are used as rocket fuel, oxygen gas is used by the astronauts to breath.

What is the difference between soild and liquid fuel rocket engines?
A solid fuel rocket engine is just what it sounds like. The fuel inside the rocket is completely solid. In a liquid fuel rocket the fuel is a liquid. Bottle Rockets that you can buy in many stores are fueled with Solid Fuel. Most liquid fuel rockets contain 2 different types of fuel. Once that fuel is mixed and ignited you get your thrust.
Can space rockets be stopped once ignited?
Depends on the type of fuel being used, solid rocket fuel can not be turn off, liquid fuel can.
What kind of fuel do they use in rockets?
Primarily there are two types of fuels used in most rockets today. The space shuttle, at liftoff, uses both. Solid fuel and liquid fuel. Solid fuel rockets are much like the bottle rockets you can buy in a fireworks store. Once they are lit, the burn all of the fuel available and then burn out. The 2 white rockets on the side of the orange tank holding the space shuttle are Solid Rocket Boosters. The large orange tank that holds the space shuttle is full of liquid full that the shuttle uses as it lifts off into space. That fuel is actually liquid.
Do all rocket use liquid fuel?
No, they do not. The side booster rockets used to launch the space shuttle, for example, use solid fuel.

What did the first rockets use for propellant?
Depends of which rocket you are talking about. Fire arrows used gun powder, but they were made to explode. Goddars rocket used liquid oxygen and gasoline. The Saturn V F1 engines used Liquid oxygen and kerosene while the J2 engines used liquid oxygen and liquid hydrogen.
