Team members must design, test and tune in a rocket that will hit a particular altitude as closely as possible in a given time window while carrying an egg (or two) with a set of rules that limit the: dimensions, motors, mass, configuration and recovery systems. Teams are given three flights in front of a judge; their best two scores are combined and the top 100 teams in the nation gather near Washington DC for a fly-off. The American winner will advance to an international competition. IHM has participated in the TARC competition for nine years and has advanced to the national finals twice and five IHM teams have made the alternate list (numbers 101-120). For the past two years IHM Rocketeers have designed and use 3D printed parts in their rockets.
