In this Science and technology issue we will be discussing rockets, and more specifically their fuel. The definition of a rocket is any vehicle propelled by ejection of the gases produced by combustion of self-contained propellants.� (Encyclopedia.com 2002) Rockets have always fascinated people. Their sizes vary greatly from the little model rockets that a least one kid in the neighbourhood had to the Saturn V rocket used in the Apollo missions that stood more than 110 m (370 ft) high and had multiple stages. The types of fuel also may vary greatly, from simple gunpowder to liquid hydrogen and even man made compound that do not occur naturally in nature, such as N₇^2-. There are even rockets that use ions and electrons for propulsion. Rockets are currently the only way that we can get into space and are only really effective form of propulsion in space. However there are down side to using rockets and you will learn about them further on in the article.

Please do not try to build a rocket with out the proper supervision and instruction. Rockets engines, and any explosive material can be potentionally dangerous and even fatal when not handeled properly. This site is purely for eduactional purposes and should not be in anyway considered to be a guide to building a rocket, or rocket engine. If you wish to build a rocket please consult someone that has experience in building them.
Thank You.
