2.  Objectives  Provide time lapse video of BalloonSat flight  Track dark current levels of CCD camera  Provide sample red filtered images  Collect temperature and humidity data  Return BalloonSat in working condition for additional missions

3.  Expected Conclusions  Telescope platform can operate continuously, 24 hours a day  Angular resolutions are comparable to HST  Sky brightness interference is negligible  Energy efficiency in controlling dark current

4. Customer Mission Statement (M) Provide research support for a low Earth orbit telescope platform by showing the emergence of stars as a BalloonSat ascends to 100,000 ft and provide dark current values to provide information about energy use on the platform. Mission Objectives (O1) Provide time lapse of BalloonSat flight using CCD video camera (from M) (O2) Track dark current levels of CCD camera using an identical CCD video camera to that in (O1) (from M) (O3) Provide sample red filtered images (from M) (O4) Fly BalloonSat to 100,000 feet under 800 grams and $200 budget on November 10 th and return in working condition ready for additional missions (from M) Objective Requirements (R1) Obtain video recording the ascent to 100,000 ft. using a CCD Video camera recorded onto an audio/video recorder and use commercial video software to create a time lapse of the mission. (from O1) (R2) Track dark current levels by taking CCD video with the lens cap on and translate it to a pixel count by time graph on an interval of one frame per minute using MaxIm DL Astronomy Software and Microsoft Excel. (from O2) (R3) Filter images taken by the CCD video camera with a red filter to show the highest contrast in the emergence of stars. (from O3) (R4) Launch BalloonSat on November 10 th by following a strict schedule and keeping detailed mass and cost budgets. (from O4) (R5) Fly BalloonSat to 100,000 feet using a helium balloon with a mass limit of 20 kg including GPS. (from O4) Level 0/1 Requirements: Mission
