TEAM LAUNCH READINESS REVIEW Evan Akselrad, Chris Anaya, Natalie Bixler, Melanie Dubin, Logan Finch, Ted Maritz, and Scott Williams November 11, 2008

Mission Overview The Balloon. Sat Flight Club shall ascend to an altitude of 30 kilometers to image the curvature and surface of the Earth, and to measure the light intensity at different altitudes to determine if commercial aviation has an impact on light intensity levels. This shall be accomplished by measuring current using solar panels attached to the payload.

Design Overview • These pictures and technical diagrams show the construction and design of the Ballon. Sat, Flight Club.

This was after we had to redesign the circuit to be parallel. This shows the raw data gathered from the logger.

We expect current to increase with light intensity as the payload ascends to altitude. Time (Seconds)

Prediction of Actual Flight Results Find noticeable discrepancy in the rate of change of light intensity at the altitude at which commercial jets fly. Such a discrepancy will indicate that the exhaust and contrails produced by jets affect the amount of light that reaches the Earth’s surface.

Worries and Concerns… At this point we feel that our biggest worry is that something will happen on launch day, such as switch not getting flipped correctly. We are concerned that connections could come loose during takeoff/the flight The HOBO taking correct readings

Proposal Compliance Matrix Mission Requirements Design shall have one additional experiment that collects science data. After flight, Balloon. Sat shall be turned in working and ready to fly again. Completed The design shall implement a light intensity experiment. The Balloon. Sat has been tested to ensure that the Balloon. Sat shall survive flight. Flight string interface tube shall be a non-metal tube through the center of the A non-metal tube has been installed into the Balloon. Sat and shall be secured to the box so it will not pull through the Balloon. Sat or interfere with the flight string. Internal temperature of the Balloon. Sat shall remain above 0ºC during the flight. Several cold tests have been conducted to ensure that the internal temperature shall not fall below 0ºC during flight. Total weight shall not exceed 1000 grams. The Balloon. Sat weighs 881. 24 grams. Each team shall acquire (not necessarily measure) ascent and descent rates of the The Helium Balloon operator shall be contacted to retrieve ascent and descent rates. flight string. Design shall allow for a HOBO H 08 -004 -02 68 x 48 x 19 mm and 29 grams. The HOBO has been implemented into the design. Design shall allow for external temperature cable. Design shall allow for a Canon A 570 IS Digital Camera 45 x 75 x 90 mm and 220 grams. Balloon. Sat shall be made of foam core. Parts list and budget shall include spare parts. All Balloon. Sats shall have contact information written on the outside along with a US Flag. Units shall be in metric. Launch is on November 15, 2008. Time and location: 7: 30 AM in Windsor, CO. Launch schedule will be given later. Everyone is expected to show up for launch. Only one team member is required to participate on the recovery. Launch and recovery should be completed by 3: 00 PM. No one shall get hurt. All hardware is the property of the Gateway to Space program and must be returned at the end of the semester. All parts shall be ordered and paid by Chris Koehler’s CU Mastercard by appointment to minimize reimbursement paperwork. All teams shall keep detailed budgets on every purchase and receipts shall be turned in within 48 hours of purchase with team name written on the receipt. All purchases made by team individuals shall have receipts and must be submitted within 60 days of purchase or reimbursement will be subject to income taxes. Have fun and be creative. The external temp. cable has been implemented into the design. The digital camera has been implemented into the design. The Balloon. Sat has been constructed with foam core. Spare parts have been included into the budget. Contact information and a US Flag has been attached to the Balloon. Sat. Units are in metric. Due to recent changes in FAA regulations, the launch will most likely occur at sunrise. All other requirements shall be followed. No one has gotten hurt. All hardware shall be returned following flight and analysis. All parts have been ordered using Chris Koehler’s CU Mastercard with proper documentation. A detailed budget has been kept. All purchases made by team individuals have been properly documented. All team individuals have been having fun and being creative throughout the project. Absolutely nothing alive will be permitted as payloads with the exception of yellow No live animals shall be present during flight. jackets, mosquitoes, fire ants, earwigs, roaches, or anything you would squish if you found it in your bed.
