2. Mission Overview Main Science Mission- Test the effect of air pressure on sound waves. Using the sounding device for a comparison to secondary science mission as a flight recorder. Secondary Science Mission- HOBO data logger used to measure internal and external temperature during flight HOBO also used to test humidity levels inside balloon-satellite. Temperature readings from HOBO data logger will act as a black box during mission. Non-Science Mission- Using main imaging hardware to take photographs during flight. Secondary imaging hardware will using ultraviolet / infrared filters to take photographs. Photographs from main and secondary imaging hardware will be used for comparison. Objective: Using Echo  ’s science systems to show a direct correlation between the amplitude of a sound wave to the pressure of the air it passes through.

3. Design Balloon satellite measuring 10 by 12cm. Optics will require cameras to be mounted facing in the same direction. Main science system will be isolated via a tube suspended by tension springs to prevent vibration and shock. Secondary science system and other systems will be tightly arranged to minimize contact with vacuum at 100,000ft, optimal use of heating system, and to minimize wiring needed. Atmospheric control system consists of a tube system that moderates airflow and removes humidity by venting atmosphere into space.

9. Budget Mass Budget- Each systems group will be reporting to budget manager. Every piece of hardware used will be weighted and kept track of by budget manager. Money Budget- Each systems group will be cleared by the budget manager for purchasing equipment. Budget manger will buy and keep records of each transaction.
