2. Mission Overview
- The purpose of the balloon satellite Astraios is to test whether or not red algae can survive the harsh environment of near space at an altitude of approximately 30,500 meters or 100,000 feet. - Possibility that our research can be applied to other extreme environments such as high mountains, the polar regions of the Earth, and the environment in which the first extra terrestrial settlements will be created when the terra-forming of Mars takes place.

3. Technical Overview Design Science
Algae Samples- 2 Cold, 2 Warm, 2 Sealed, 2 Not Sealed
Sealed bags are pressurized at sea level, thus testing whether pressure or temperature will kill the algae sample
The samples in the cold will be in cube offshoot(s) on top of main cube
Two HOBOs- 1 for temperature and humidity, and 1 for pressure
We will test the structure, tether connection, and insulation before launch in order to maximize likelihood of mission success

7. Special Features
Our sat will contain 4 separate samples of algae. Two will be pressurized in plastic bags. We will place two samples in a structure integrated onto the outside of the cube to test the effects of extreme cold

8. Testing We will perform structure tests to ensure survivability
Once everything is assembled we will do a cooler test to make sure the sat will survive the extreme cold
We will test the algae by-
Placing it in a cooler of dry ice to test how it will survive
We will also study it with a microscope to familiarize ourselves with its aspects

13. Fearless… Nuff said! Biggest Worries… Air Depletion UV Radiation
Lack of gases for algae to survive off
UV Radiation
Avoiding the mutation and death of the algae
Temperature
Extreme temperatures may cause algae to die
Landing Impact
Limiting damage to algae samples
