Team T.W.S.S. Conceptual Design Review

1. Team T.W.S.S.Conceptual Design Review Victor Taberski, Ryan Walker, Allen Marshall, Matt Kerwin, Andrew Winthrop, Steven Ramm September 23, 2008 UAIOOU – (Upper Atmosphere Infrared Optical Observing Unit)

2. Mission Statement Our goal is to create a Balloon Sat that will simultaneously image the stars in the visible and in the infrared spectrum. This will give a reasonable comparison of star image quality in the two bands at various altitudes. Additionally this will allow us to plot what altitudes the stars become visible through the Earths Atmosphere in the two bands to Assist with future high altitude observations.

3. Mission Overview • Goals: • Will determine when stars become clear in the visible spectrum. • Will determine when the stars become clear with frequencies below that of the visible spectrum. • Gain comparison of same view field in both spectrums.

9. Management • Ryan Walker- Team Czar: Coordinate all other programs on the project, maintain team budget, and assist as needed on other projects. • Victor- Systems Engineer: Help with structural design. Keep schedule to ensure that team is on track. Work with other engineers to integrate individual systems together and to debug systems. Ensure Balloon Sat remains within mission guidelines. • Andrew Winthrop– Structural Engineer: Design structure of Balloon Sat, work with fabrication and assembly of parts. Design Passive thermal system. Help where needed. • Matt Kerwin- Electrical Engineer: Design power systems and work with other members of team to ensure that all of the systems will have enough power, also does HOBO programming. • Allen Marshall- Science Engineer 1: Work with Infrared Camera and ensure that it can log retrievable data during flight, will also program data recorder for this unit. • Steven Ramm– Science Engineer 2: Work with HP Smart camera to make sure it is mechanically and electrically compatible with the rest of the Balloon Sat. Also programs Camera.

10. Budgets • Budget: $150.00 limit • $0.00 – HOBO • $0.00 – Foam Core • $0.00 – Heater (3 9V batteries) • $0.00 – Timing Circuit (1 12V battery) • $0.00 – Cannon Digital Camera • $60.00 ≈ Infrared Camera • $0.00 – Aluminum Tape • $0.00 – Space Blanket Sheeting • $0.00 – Insulation • $0.00 – Central Tube • $20.00 – Transparent Material (i.e. Plexiglas) • $0.00 – Extra Batteries • $80.00 – Total Weight Budget: 1000g limit 200g Visible Light Spectrum Camera 138g 9v Batteries 32g Heater 33.5g Timer 7.3g Timer Battery 300g Weight Allotment For the Foam core 72.6g PVC Pipe 200g Infrared Camera 983.4g Total

11. Biggest Worries • Successfully Programming the infrared camera to achieve synchronized imaging with the other camera • Keeping temperature of Balloon Sat in Functional Range • Staying on schedule to allow sufficient time for testing
