The NAR was created in 1957 as an advocate of the model rocketry hobby. Over the past four decades the hobby has grown to encompass rocket motor types and performance unavailable to the modeler at the NAR’s inception. In response to this growth the NAR offers a certification process which permits individuals to purchase and use rocket motors whose physical constraints and performance exceed traditional model rocket boundaries. Rocket motors which exceed model rocketry motor definitions and the models that use these motors are collectively referred to as high power rocketry
The National Association of Rocketry (NAR) is a non-profit tax-exempt scientific organization dedicated to consumer safety, youth education, and the advancement of technology in the hobby of spacemodeling (sport rocketry) in the United States. Founded in 1957, the NAR is the oldest and largest spacemodeling organization in the world with over 5900 members and 165 affiliated clubs across the U.S.
The NAR supports all aspects of safe consumer sport rocket flying, from small model rockets with youth groups to very large high power rockets with serious adult hobbyists. It is a recognized national authority for safety certification of consumer rocket motors and user certification of high- power rocket fliers in the U.S. It is the author of safety codes for the hobby that are recognized and accepted by manufacturers and public safety officials nationwide. The NAR plays a strong role in the establishment of national rocketry safety standards for public safety officials through its participation in the National Fire Protection Association.
The mission of RiMRA is to provide a safe venue for launching amateur rockets and bring together people interested in amateur rocketry – whether they are new to the hobby or long time enthusiast. RiMRA promotes amateur rocketry as a tool for teaching engineering, mathematics & the physical sciences.
