  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 • Prove: 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 • Dropped three times from four stories • 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 • Whip Test • Swung on various lengths of rope, various speeds, many times • 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. • Kick Test • Kicked down six flights of stairs three times • Results: same as drop test • Revision to design: same as drop test • Cold Test • 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! • 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. Cold Test 1: DATA Cold Test 2: DATA 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

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

  8. Flight Results • We expect to see an increase in radiation as altitude increases. • UV: 0 - 0.6 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

  9. Concerns • Inserting resistors for UV sensors • Waking up early • Calibrating data

  10. Compliance Matrix
