| Sumario: | The Cedar Stratos Southern Utah University balloon project had two fundamental goals: first, to accurately model the static and dynamic behavior of the balloon in one dimension and calculate parameters such as float altitude, float pressure differential, superpressure altitude, terminal velocity, and ascending rate; and second, to accurately and thoroughly document the process of preparing, testing, and launching a pico balloon. We successfully launched 3 identical aluminized mylar balloons. The analytical evaluations (statics and dynamics) predicted correctly the experimental results. This paper focuses on the physical aspects of the launch procedure and balloon’s characteristics.
