High-power Rocketry
High-power rocketry is a hobby similar to model rocketry. The major difference is that higher impulse range motors are used. The National Fire Protection Association (NFPA) definition of a high-power rocket is one that has a total weight of more than and contains a motor or motors containing more than of propellant and/or rated at more than 160 Newton-seconds (40.47 lbf·s) of total impulse, or that uses a motor with an average thrust of or more. Types High-power rockets are defined as rockets flown using commercially available motors ranging from H to O class. In the U.S., the NFPA1122 standard dictates guidelines for model rocketry, while NFPA1127 is specific to high-power rockets. In most U.S. states NFPA1122 has been adopted as part of the legal code. A smaller number of states use NFPA1127. Associations The Tripoli Rocketry Association and the National Association of Rocketry are the major sanctioning bodies for the hobby in the US, providing member certifications, and ...

Amateur Rocketry
Amateur rocketry, sometimes known as experimental rocketry or amateur experimental rocketry, is a hobby in which participants experiment with fuels and make their own rocket motors, launching a wide variety of types and sizes of rockets. Amateur rocketeers have been responsible for significant research into hybrid rocket motors, and have built and flown a variety of solid, liquid, and hybrid propellant motors. History Amateur rocketry was an especially popular hobby in the late 1950s and early 1960s following the launch of Sputnik, as described in Homer Hickam's 1998 memoir '' Rocket Boys''. One of the first organizations set up in the US to engage in amateur rocketry was the Pacific Rocket Society established in California in the early 1950s. The group did their research on rockets from a launch site deep in the Mojave Desert. In the summer of 1956, 17-year-old Jimmy Blackmon of Charlotte, North Carolina, built a 6-foot rocket in his basement. The rocket was designed to be po ...
