The history of rockets goes back to at least the 13th century, and military and recreational display use dates from that
time.[1] Widespread military, scientific, and industrial use did not occur until the 20th century, when rocketry was the
enabling technology of the Space Age, with man visiting the moon.
Rockets are used for fireworks and weaponry, ejection seats and launch vehicles for artificial satellites, human
spaceflight and exploration of other planets. While inefficient for low speed use, they are, compared to other propulsion
systems, very lightweight and powerful, capable of generating large accelerations and of attaining extremely high speeds
with reasonable efficiency.
Chemical rockets store a large amount of energy in an easily-released form, and can be very dangerous. However,
careful design, testing, construction, and use minimizes risks.
