Test Name Specifics DateStructure Tests Perform Structure Tests (whip, roll,
drop) Oct 6, 2011
Cockroach Containers
Test the cockroaches containers (condensation potential, strength)
Oct 6, 2011
Isolation Test Test cockroaches to get base data (temperature they freeze at, livability in containers without food or water for extended periods of time)
Oct 6, 2011
Cooler Test (structure, hardware, and cockroaches freezing)
Oct 21, 2011
Day in the life (DITL) Testing Camera functionality, hardware functionality, ensure the entire satellite is integrated and functional.
Oct 21, 2011
Integration and final testing
Integrate subsystems and perform final testing
Oct 19-24, 2011
Test Plan
• Testing so far:• Drop Test
• Testing to be done:• Drop, Whip, & Roll Test• DITL and Cold Test• Isolation Test
Test Plan
. Most detrimental condition
. Effects at important altitudes
. 12,200 meters . Survival of cockroaches
