MC2 is affiliated with two rocketry associations:
The following excerpt is from the NAR webpage history section:
The National Association of Rocketry (NAR) was founded in 1957, and is the oldest and largest spacemodeling organization in the world with over 6100 members and 125 affiliated clubs across the U.S. It was established in 1957 by Orville Carlisle and G. Harry Stine and is currently headed by President Ted Cochran. It supports all aspects of safe consumer sport rocket flying, from small model rockets with youth groups to very large high power rockets flown by adult hobbyists.
NAR is a national organization. NAR supports lo, mid and high powered sport rocketry. NAR has a high power certification program that is also recognized by Tripoli.
2. Tripoli Rocketry Association
The following excerpt is from the TRA webpage:
Tripoli is a non-profit organization dedicated to the advancement and operation of amateur high power rocketry. Our members are drawn from the United States and 22 additional countries across the globe. High Power Rocketry is an educational, safe and exciting hobby enjoyed by thousands world-wide!
Tripoli members come from all walks of life and all ages. We have construction workers, medical staff, programmers, truck drivers and anything else you can think of. There are even a few rocket scientists among us!
Tripoli began in 1964 as a high school rocketry club and has evolved into an international amateur high power rocketry association. Tripoli has a high power certification program that is recognized by NAR. In addition Tripoli offers supports research launches.
Both organizations work cooperatively and often rocket clubs, such as MC2, are affiliated with both associations. Both organizations are involved in community outreach and work with NASA on various projects.
