  2. Overview • Mission Description • Mission Goals • System Requirements • System Overview • Mass Budget • Project Organization • Budget • Schedule

  3. Mission Description • To Design and Build a Light Weight, Energy Efficient Photometer • To Obtain a Vertical Profile of Ozone Concentration as a Function of Altitude

  4. Mission Goals and NASA Benefits • To Develop an Understanding of Ozone Concentration as a Function of Altitude • To Develop a Cost Effective Method to Measure Ozone Concentration as a Function of Altitude • To Develop a Clear Understanding of Photometric Analysis • Demonstrates ability to measure ozone profile in a Mars-like environment

  5. System Requirements • Low Pressure Mercury Lamp • Emission Spectrum Includes a line at 253.7nm • Interference Filter Centered at 253.7nm • Shield Photodiode Detector From Ambient Light • Fans Placed at Inlet and Outlet to Ensure Adequate Sampling • Ozone Concentration Measured Continuously as a Function of Altitude • Temperature and Pressure Measurements Recorded During Flight • All Data Stored on Board Using a HOBO Data Acquisition System

  6. System Overview
