Pegasus MSFSatElysiumLaunch Readiness Review Jordan Burns, Brenden Hogan, Miranda Link, Cody Spiker, Chris Dehoyos, HemalSemwal November 1st, 2011
Mission Overview Mission Statement: • “To test the effects of high altitude flight upon a closed container containing Streptococcus mutans bacterium, and recording their response to discover if harsh high altitude effects bacterial reproduction and survival.” Why? • To test the validity the of the recorded results of the 1967 flight of Surveyor III.
Design Overview • 21x21x12 cm • 2 levels • 6 different samples, 3 locations with varying conditions • Motorized door • 4 sensors (2) • Temperature • Pressure • Visible Light
Hardware/Software Testing • Software / Hardware Testing • No major problems occurred with our software, besides getting everything to run right. • FIX: • Trial and Error testing and corrections • Cooler Test • Data collected from all sensors-compared to control data • EXCEPT HOBO • Malfunction: only programmed to output voltage readings, not temperature and humidity
Average: 13 No Light: 0 Absolute Light: 1024
Close Door Open Door Average: 33.5 degrees Celsius
Cooler Testing Open Door Close Door Average: 25.3 degrees Celsius
Cooler Testing Average: 83788.67 Pascals Open Door Close Door
Incubation Testing • Each test has been overlapped in order to isolate each potential problem that may occur. • Multiple tests show the desired traits from a healthy culture are: • Translucent, White Colonies • Expansion Growth • Colony size larger than 1 mm • After analysis of S. mutans, it was discovered that this strand is non-aerobic and a vacuum test would be inconclusive towards any results.
Flight Samples-To be tested • The actual flight cultures are going to be one day shy of full maturity. • This means that the actual cultures for flight will be grown on the Thursday before launch day, November 4, 2011. • Being slightly immature, these cultures will be at their most vulnerable point of outside factors affecting their growth. • Being exposed at this point means that after flight and exposure, any change in the bacteria will be the most noticeable.
Structural Testing • Drop/ Roll Test • Our drop test revealed that our structure was NOT SOUND • The slits for our shelves were too deep • Our tape was not secure • FIX: • Pre-cut BASES to slide the shelves in • Cleaner and more precise cuts were made, and more efficient gluing. • Whip Test • revealed that the solid faces of our structure could not support the pulling of the tether. • FIX: • A wall that runs across the middle of the CubeSatto give the wall support
Expected Results • We expect to find that the bacteria will be resilient enough to survive both the extreme radiation and temperature environments. • The samples will grow normally after the flight
Worries • Science Failure: The motorized door will not open. No light radiation will be let into satellite environment. • Structural Failure: The motorized door will rip off during burst
