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.

Team Worries
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
