The Team America Rocketry Challenge (TARC) is an annual American model rocketry competition for students in grades seven to 12 sponsored by the Aerospace Industries Association and the National Association of Rocketry. Co-sponsors include NASA, United States Department of Defense, the American Association of Physics Teachers and the Civil Air Patrol.
The event receives local and national media coverage and usually draws well-known representatives of the Defense Department, NASA, the FAA, and other government agencies. Past National Fly-Offs have been attended by United States Secretary of Defense Robert Gates, Apollo 11 astronaut Buzz Aldrin, Rocket Boys author Homer Hickam, former NASA Administrator Sean O'Keefe, U.S. Senator Mike Enzi, and current NASA Administrator, Charles Bolden.
The 2010, 2011, 2013, 2015, and 2016 International Fly-Offs were won by the American winners of TARC.
The competition began in 2002 in celebration of the 100th anniversary of flight, but due to a high level of interest became an annual occurrence. TARC fosters interest in aerospace engineering careers among its participants, and the National Fly-Off in May is an opportunity for corporations, universities, and the armed services to attract students.
The requirements for each year's challenge are announced during the summer. Teams generally meet early in the school year, and must make official qualifying flights by early April. A team only has three chances to fly an official qualification attempt; only scores from flights that meet the contest requirements, are safe, and don't break the egg(s) can be submitted. Typically, about 60 percent of participating teams submit at least one qualification score. The teams with the top 100 qualifying scores submitted in April compete in the National Fly-off that is held during May at Great Meadow in The Plains, Virginia.
