The history of rockets goes back to at least the 13th century.Rockets in Ancient Times (100 B.C. to 17th Century) By the 20th century, they have enabled human spaceflight to the Moon. In the 21st century, they have made commercial space tourism possible.

Rockets are used for fireworks and weaponry, as 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 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 minimize the risks.

Larger rockets are normally launched from a launch pad which serves as stable support until a few seconds after ignition.

In antiquity

The availability of black powder (gunpowder) to propel projectiles was a precursor to the development of the first solid rocket. Ninth Century Chinese Taoist alchemists discovered black powder while searching for the Elixir of life; this accidental discovery led to experiments in the form of weapons such as bombs, cannon, incendiary fire arrows and rocket-propelled fire arrows.

Exactly when the first flights of rockets occurred is contested. Some say that the first recorded use of a rocket in battle was by the Chinese in 1232 against the Mongol hordes. There were reports of fire arrows and 'iron pots' that could be heard for 5 leagues (15 miles) when they exploded upon impact, causing devastation for a radius of 2,000 feet, apparently due to shrapnel.A Brief History of Rocketry The lowering of the iron pots may have been a way for a besieged army to blow up invaders. The fire arrows were either arrows with explosives attached, or arrows propelled by gunpowder, such as the Korean Hwacha.（正大九年）其守城之具有火砲名「震天雷」者，铁罐盛药，以火点之，砲起火发，其声如雷，闻百里外，所爇围半亩之上，火点著甲铁皆透。（蒙古）大兵又为牛皮洞，直至城下，掘城为龛，间可容人，则城上不可奈何矣。人有献策者，以铁绳悬「震天雷」者，顺城而下，至掘处火发，人与牛皮皆碎迸无迹。又「飞火枪」，注药以火发之，辄前烧十余步，人亦不敢近。（蒙古）大兵惟畏此二物云。(Rough Translation: 1232 Among the weaponry at the defense city 1 are the "thundercrash", which were made of iron pot, and filled with drugs powder, when lighted with fire, it exploded, making a noise like thunder. It could be heard over 100 li, and could toasted more than a third of an acre, moreover it could penetrate the armours and iron. The 2 soldiers employed a siege carriage cloaked with cowskin and advance to the city below, they grubbed a niche on the city-wall, which could spare a man between. The 3 defenders atop did not know what to do, later an advice had offered. The pot was then dropped with an iron string from the fortress, it reached to the niche area and exploded, men and carriage were blown to pieces without trace. They also have the "flying fire-lance", which was infused with drug powder and ignited it, it flames within a range of over ten paces on the front, men are not dare to near. It is say that the 4 soldiers only terrify by these two objects.) History of Jin ch. 113
