Slide 2
Effects of high altitude Individual effects of high altitude
Space elevator protection Lack of applicable information Mission
Overview
Slide 3
Arduino to measure: Pressure Temperature Humidity HOBO for
temperature and humidity Spy cameras LED array Design Overview
Slide 4
Functional Block Diagram
Slide 5
Slide 6
Originally had accelerometer Added 2 pressure sensors Added 2
humidity sensors Changed from 2 to 4 cockroaches Added additional
LEDs Design Overview
Slide 7
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 Results and Analysis
Slide 8
Pressure (mb) Duration (s) Pressure Start of depressurization
Restored pressure
Slide 9
Results and Analysis External Temperature Launch Burst Landing
Tropopause
Slide 10
Results and Analysis Internal Temperature Landing Burst Launch
Tropopause
Slide 11
Slide 12
Slide 13
Cockroach
Slide 14
Slide 15
Arduino Failure Did not record any data Fixed by shorting reset
pin Data now recording Failure Analysis
Slide 16
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 Conclusions
Slide 17
Keep subsystems better isolated while loading cockroaches Test
arduino in morning before at launch site Get programing done
earlier DO NOT DRIP EPOXY Lessons Learned
Slide 18
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 Ready to fly again

I promise you, this class is harder than you think it is. Be
prepared for all-nighters, because youll 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 dont think something
needs to be tested, test it anyway. Teamwork is the most important
thing to a successful satellite. If you dont get along with someone
on your team, suck it up and put the team on your back. For Madden.
