1 Team Dionysus Critical Design Review Alijah Smith, Chris Koncilja, Elise Kowalski, Josh Tiras, Mike Beach, Becca Seigel 10/06/09

2 Organization Chart

3 Mission Overview –Objective: Use infrared sensor and an ultraviolet sensor to determine the flux of infrared and ultraviolet light throughout the troposphere and lower stratosphere –We expect to prove that UV and IR light intensity increase with altitude –Hypothesis: UV and IR light intensity increase with altitude –Understanding penetration of light can help protect people from radiation from the sun. Large amounts of radiation can damage people’s skin and have other negative effects on other life on earth.

4 Requirements Flow Down Level 0Survive Mission Primary Mission Secondary Mission Making it to Launch Level 1Testing Structure Purchase and test sensors Test camera, pressure, and temperature sensors Keeping schedule, budget, and mass budget

5 Design Use sensors attached to top of cube and convert the data received from amps to volts. Parts –Ultraviolet Sensor – ordered –Infrared Sensor – ordered Expected to arrive Oct. 6 th, 2009

11 Test Plan Payload Testing: Whip, Drop, Cold, Stair Tests Sensor Testing: AVR test, Calibration, Blacklight, Heat lamp Schedule o11th – Team meeting: Construction o12th – Team meeting: Construction, empty shell/mass sim. test o13th – Team meeting: Construction, sensor tests o18th – Team meeting: Construction, payload tests o20th – Team meeting: construction, sensors and structure tests o25th – Team meeting: All Testing Complete o27th – Pre Launch Inspection o29th – Mission Simulation

12 Expected 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
