Mission OverviewMission Overview
• 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.

Expected ResultsExpected 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
Biggest WorriesBiggest Worries
• Sensor Accuracy/Error
• Severity of Impact
• Parachute Failing
• Finding proper resistor for amps to volts conversion
