Mission Overview
Ascend to 30 km, collecting data regarding temperature, air density, sound
Compare air density to sound to confirm expected relationship
Compare amounts of Carbon dioxide with sound data
Hypothesis: air density goes down=frequency increases, amplitude decreases
Large amounts of carbon dioxide result in new recorded frequencies
Why? Use sound as means of detecting gas

Post Flight CO2 Test
Failure
MICROPHONE WASN’T TURNED ON. Temp Probe
Brunton temp Post-test
Next Flight: New temp probe Don’t make same mistake twice.
Conclusion
Teamwork is important Work ahead WE FAILED TO TURN EVERYTHING ON.
Never again Correlation between CO2 undiscernable
with further ground testing Engineering involves failing
What to do different?
Smaller, warmer BalloonSat PRESS DA BUTTON! Increase amplitude of speaker Press just one itty bitty button Test HOBO more Test for a gas that is more prevalent than
carbon dioxide
Fly Again
For storage, batteries in weather channel should be taken out
Isolate speaker For flight, TURN ON and insert
microphone and weather channel Seal top panel Flip speaker switch, heater switch Paper-clip the camera switch
Core Requirements
Requirement Result
BalloonSat internal temperature shall remain above -10 degrees Celcius
Unknown
BalloonSat shall not exceed 850 grams
BalloonSat is currently overweight (app. 940 g)
Budget shall not exceed $300.00 Final Budget : $283.97
Materials/Components (HOBO, foam core, temp probes, flight string/tube, camera, scientific experiment, flag,heater)
All necessary components are accounted for
