Team Pegasus MSF: BalloonSat SatElysium Conceptual Design Review Jordan Burns Miranda Link Brenden Hogan Cody Spiker Chris Dehoyos Hemal Sewal September 20, 2011

Mission Overview Objective: Test and record the effects of a near space environment on several cultures of Streptococcus mutans. Purpose: Determine how bacteria cultures respond to the lack of pressure, extreme temperatures, and radiation present in near-space. Why: Test the validity the of the recorded results of the 1967 flight of Surveyor III. According to NASA’s results, we believe that we will find that bacteria not only survive, but actually thrive, in the harsh environment of space.

Design We will accomplish our mission by creating a balloon satellite in which our samples will be exposed to differing conditions. Three sets of samples will be put in their own conditions. – Number 1 will be in a lower section of the sat with the electronics and will have a heater warming it – Number 2 will be in the upper half of the sat isolated from light but not temperature – Number 3 will be in the upper half of the sat exposed to light and temperature The following slides will illustrate the method of doing this.

1. Bacteria cultures will not grow properly prior to launch 2. Door mechanisms will not close correctly 3. Securing Petri dishes to structure 4. Forgetting about the basics because we are so worried about the more complicated components of the satellite. 5. Insulation, insulation, insulation. 6. Losing the entire BalloonSat Team Worries
