1. Clean Air Project: Team Big Green SpaceGasm Launch Readiness Review Hillary Beltran, Edward Crawford, Nicole Harris, Edward Lowe, Emily Proano, and Kevin Wong November 2, 2010

2. Mission Overview  Mission objective: Take measurements of the concentrations of carbon monoxide, carbon dioxide, and methane gases  Hypothesis: Concentrations have increased during the course of the year  Not enough time to see effects of transition  Effects of Fourmile Canyon, Loveland, Grand County, Boulder Canyon fires 2

3. Mission Overview  Purpose of Mission: The team’s interest in the quality of air and changes that were recently experienced over the past few years  World’s recent transition to more environmentally sustainable resources and fuels  Recent forest fires in Colorado  Document any measured changes  Data retrieved from this flight will provide standard 3

4. Design Overview  Three Sensors: CO, CO2, and Methane  Arduino and MicroSD Shield  Required Components  Camera, Hobo, Heater, and Batteries

5. Cooler Test  Maintained above -10* C for over 2 hours  Dropped below after 2 hours  Due to heater failure because of batteries running out of power

6. Science Test (Car Test)  Held box behind exhaust pipe of car  Took away and replaced repeatedly

7. Structures Tests  Three Rounds  First: survived kick, but weights broke through bottom on drop  Second: whip test. Sturdy, no damage  Third: no damage with standard drop and kick, and no damage dropping from seventh story window

8. Predicted Flight Results  All gas readings within calculated standard range  A drop in measured gases above 16km  Overall rising trend in gases due to fires

9. Biggest Worries  Power Failure due to temperature, leading to a heater failure  Stable readings from the sensors  Analysis of date afterwards 9

10. Requirements Flow Down: Level 0 10 Numb er DerivationDescription 1 M.S. Payload must ascend to an altitude of approximately thirty kilometers with a balloon provided by the Edge of Space Sciences 2 M.S.Payload must collect and store science data related to the mission objective 3 M.S. The payload must carry an active heater system, keeping the internal temperature of the payload above -10°C 4 M.S.The payload must be constructed from foam core 5 M.S. The total mass of the payload must not exceed 850 grams and the budget of the project must not exceed three-hundred dollars. 6 M.S.The payload must allow for a HOBO H08-004-02 and the provided external temperature cable 7 M.S.The payload must allow for a Canon A570IS Digital Camera with two AA lithium batteries 8 M.S. The payload must have contact information written on the external of the payload, alongside an United States flag 9 M.S.The team will be ready to launch on November 6, 2010, at Windsor, Colorado, at 6:50 AM. 10 M.S.The team shall adhere to all safety procedures outlined in the proposal

11. Requirements Flow Down: Level 1 11 NumberDerivationDescription 1 O1Payload must remain attached to the flight string during the mission 2 O7The payload must be functional, retrievable, and capable of flying multiple times. 3 O2 The payload will carry carbon monoxide, carbon dioxide, and methane gas sensors to record the concentrations of each gas at different altitudes 4 O5 The entire payload, including all electrical components and structural materials, will weigh 781 grams 5 O6 The HOBO H08-004-02 shall measure and record measurements of internal temperature and the provided external temperature cable will record external temperatures during the mission. 6 O7A Canon A570IS Digital Camera will take and store images during the flight. 7 O2 Program the Arduino microcontroller with the integrated development environment using the Java programming language 8a O2Interface the carbon monoxide gas sensor to the Arduino microcontroller 8b O2Interface the carbon dioxide gas sensor to the Arduino microcontroller 8c O2Interface the methane gas sensor to the Arduino microcontroller 8d O2 Test the functionality of the gas sensors individually and then test the functionality of the sensors integrated together on the Arduino microcontroller by placing the sensors behind the exhaust pipe of a running automobile that belongs to a member of the team. 8e O10The team will adhere to all safety measures and protocol when testing system functionality. 9 O2, O3 Provide the necessary power to each electrical component and ensure that the recorded data is being properly stored 10 O1, O2, O3, O4 Create a structure that can withstand the forces and extreme temperatures experienced during flight 11 O10 The team will have a functional and flight-ready payload to turn-in on check-in, November 5, 2010, and launch day, November 6, 2010.
