1. Team Dionysus Launch Readiness Review Elise Kowalski, Michael Beach, Josh Tiras, Chris Konciljia, Alijah Smith, Becca Seigel November 5, 2009

2. Mission Overview Objective: Use an infrared sensor and an ultraviolet sensors to determine the flux of infrared and ultraviolet light throughout the troposphere and lower stratosphere Objective: Use an infrared sensor and an ultraviolet sensors to determine the flux of infrared and ultraviolet light throughout the troposphere and lower stratosphere Prove: UV and IR light intensity increase with altitude Prove: UV and IR light intensity increase with altitude Hypothesis: UV and IR light intensity increase with altitude Hypothesis: UV and IR light intensity increase with altitude Large amounts of radiation can damage people’s skin and have other negative effects on other life on earth. A greater understanding of light penetration can help further protect people from radiation from the sun.

3. External Design Triangular Prism Flat Top Upper level sides slanted at 12 ° (average sun angle during flight)

4. Internal Design Heater placed near camera batteries and 9Vs to avoid overheating the AVR and to keep the camera batteries warm Sensors on upper level slanted sides in addition to switches (one UV on each side, IR paired with UV on one side) 1.5 cm layer of insulation covering all internal sides (not shown)

5. Test Results Drop Test Drop Test Dropped three times from four stories Dropped three times from four stories Results: minor indentation in corners, mass simulators (rocks + duct tape) loose. Results: minor indentation in corners, mass simulators (rocks + duct tape) loose. Revision to design: interior of box made smaller so hardware doesn’t slide or rub against each other if jostled Revision to design: interior of box made smaller so hardware doesn’t slide or rub against each other if jostled Whip Test Whip Test Swung on various lengths of rope, various speeds, many times Swung on various lengths of rope, various speeds, many times Results: no damage to mass simulators, flight tube hole slightly torn Results: no damage to mass simulators, flight tube hole slightly torn Revision to design: Paperclip bent underneath washer instead of above, flight tube made shorter, new holes cut in flight tube so paperclip won’t allow tube to slide within box. Revision to design: Paperclip bent underneath washer instead of above, flight tube made shorter, new holes cut in flight tube so paperclip won’t allow tube to slide within box. Kick Test Kick Test Kicked down six flights of stairs three times Kicked down six flights of stairs three times Results: same as drop test Results: same as drop test Revision to design: same as drop test Revision to design: same as drop test Cold Test Cold Test Placed in cooler with dry ice for two hours, done three times Placed in cooler with dry ice for two hours, done three times Results: problems with heater, AVR and camera shutting off less than half way through test- later found out reading data wrong…GOOD TEST! Results: problems with heater, AVR and camera shutting off less than half way through test- later found out reading data wrong…GOOD TEST! Revision to design: Increased dimensions of box to include thick insulation on all sides, hardware rearranged to make camera batteries and 9V batteries closer to heater Revision to design: Increased dimensions of box to include thick insulation on all sides, hardware rearranged to make camera batteries and 9V batteries closer to heater

6. Results: unsuccessful, interior of box too cold, hardware and camera shut off Revision to deign: added.5 cm insulation to each interior wall Results: better, still unsuccessful, interior of box too cold Revision to deign: increased dimensions 1 cm in order to add 1.5 cm insulation to each interior wall Cold Test 1: DATACold Test 2: DATA

7. Results: successful, interior of box remained very warm Revision to Design: none Cold Test 3: DATA

8. Flight Results We expect to see an increase in radiation as altitude increases. We expect to see an increase in radiation as altitude increases. UV: 0 - 0.6 Watts per m^2 per nanometer UV: 0 - 0.6 Watts per m^2 per nanometer IR Ground: 0.5-1 Watts per m^2 per nanometer IR Ground: 0.5-1 Watts per m^2 per nanometer IR at altitude: 1-1.5 Watts per m^2 per nanometer IR at altitude: 1-1.5 Watts per m^2 per nanometer
