Mission OverviewOBJECTIVE: To design, build, and launch a BalloonSat which will test two types of power generation systems (solar panels and propellers) under flight conditions. The mission will also collect data on humidity, temperature and take pictures during flight. EXPECTED DISCOVERIES:• Amount of power generated by solar panels under flight
conditions• Amount of power generated by propellers under flight conditions• Which power generation system is most effective at various
altitudes and conditions
Mission Overview (cont.)
HYPOTHESIS• The solar panels will provide more overall power generation but
during certain flight periods the propeller will be more efficient
Mission Overview (cont.)
PURPOSE• Gain knowledge of solar panel and propeller power generation in
different atmospheric conditions• Compare data from the power generation systems to discover
which system is more effective overall and at different points during flight
• Learn about renewable energy sources for flights within Earth's atmosphere
• Generate information that future BalloonSats may utilize in selecting power systems

Expected Results• gain information about the efficiency of power generation under
different conditions• We expect...
o Solar panels will generate more power overallo From launch to 12 km- propellers will generate more powero 12 km to burst- solar panels will generate more powero Burst to parachute deployment- solar panels will continue to
generate efficiently with some sporadic generation from the propellers
o Parachute deployment to landing- solar panels and propellers will generate power on a comparable level
• Data shall be analyzed post-landing to determine which power generation system is actually most efficient under varying flight environments

Propeller• What should we build the propeller out of?• What type of propeller do we want to use?
Voltmeters• Integrating the Voltmeters with the Arduino
