Rocket, one transportation to outer space or moon at present. self-propelled device that carries its own
fuel, as well as the oxygen, or other chemical agent, needed to burn its fuel.
Most rockets move by burning their fuel and expelling the hot exhaust gases that
result. The force of these hot gases shooting out in one direction causes the
rocket to move in the opposite direction. A rocket engine is the most powerful
engine for its weight. Other forms of propulsion, such as jet-powered and
propeller-driven engines, cannot match its power. Rockets can operate in space,
because they carry their own oxygen for burning their fuel. Rockets are
presently the only vehicles that can launch into and move around in space.
A rocket can be as simple and small as a
firework, which has a small amount of thrust, or as complex and powerful as the

which were used in the War of 1812, are referred to in a line of the United
