  1. Team Victorious SecretFinal Presentation Crawford Leeds Jacob Broadway Tanya Hardon Devan Corona Dylan Reed November 29, 2011

  2. Mission Overview • Effects of high altitude • Individual effects of high altitude • Space elevator protection • Lack of applicable information

  3. Design Overview • Arduino to measure: • Pressure • Temperature • Humidity • HOBO for temperature and humidity • Spy cameras • LED array

  4. Functional Block Diagram

  5. Design Overview Originally had accelerometer Added 2 pressure sensors Added 2 humidity sensors Changed from 2 to 4 cockroaches Added additional LEDs

  6. Results and Analysis Predicted: • Video cameras would record whole flight • Arduino would collect data • Burst at 30,480 m • HOBO would collect data successfully • 2 cockroaches would survive • Structure would hold What really happened: • Video cameras shut off at 35 and 37 minutes • Arduino did not collect data • Burst at 22,000 m • HOBO collected temperature and humidity data successfully • 2 cockroaches survived • Structure held

  7. Results and Analysis Pressure Start of depressurization Pressure (mb) Restored pressure Duration (s)

  8. Results and Analysis External Temperature Launch Tropopause Landing Burst

  9. Results and Analysis Internal Temperature Landing Launch Burst Tropopause

  10. Cockroach

  11. Failure Analysis • Arduino Failure • Did not record any data • Fixed by shorting reset pin • Data now recording

  12. Conclusions • Two unheated cockroaches died • Two heated cockroaches lived • Cold is most detrimental • Most important for high altitude space elevator is thermal control • Unsure of effects of pressure on humans                    • Humans less resilient than cockroaches • Can only know for sure cold at 22,000 m will kill a person

  13. Lessons Learned Keep subsystems better isolated while loading cockroaches Test arduino in morning before at launch site Get programing done earlier DO NOT DRIP EPOXY

  14. Ready to fly again Isolate and feed cockroaches until launch Keep satellite away from extreme environmental factors. To activate payload: Put cockroaches in containers and seal two pressured boxes using epoxy 24 hours before launch. Set hobo to run at the designated time. Turn on all switches including camera button. Reset micro SD shield until yellow light blinks. Turn on both video cameras Seal box with aluminum

  19. Message to next year I promise you, this class is harder than you think it is. Be prepared for all-nighters, because you’ll probably pull at least one. You will work a ridiculous amount of hours in preparation for the flight, but as soon as that balloon takes off, it will suddenly all be worth it. Also, TEST EVERYTHING. If you don’t think something needs to be tested, test it anyway. Teamwork is the most important thing to a successful satellite. If you don’t get along with someone on your team, suck it up and put the team on your back.  For Madden.
