Will microgravity prevent Aedes albopictusmosquitoes from developing into pupae? • Probably. • Mosquito larvae float to the surface to breathe and mature into pupae. • Without gravity, they lack a mechanism to float and so cannot breathe. Question and Answer (?)
Hatching = 1 to 3 days Turning into an adult = 2 days Mosquitoes larvae breathing Turning into pupae = 5 to 10 days Mosquito Life Cycle
Volume 1 includes: dry mosquito eggs and nutrients (brewer’s yeast and lab chow). • Volume 2 includes: water and air. • Volume 3 includes: fixative (10% neutral buffered formalin). • Preliminary experiments will be done to determine the proper amounts for all substances. Experimental Overview
At launch, eggs will be dry. • When Clamp A is released, water will activate development. • Experiment will continue 9 days. • Then astronauts will release Clamp B to stop development and fix mosquitoes when they should have matured into pupae. • Compare results to ground truth experiment. Experimental Overview
Mosquitoes can serve as food stock for crayfish and tilapia. In turn we can eat crayfish and tilapia. • In a journey to the stars, the astronauts might enjoy a break from dehydrated food. • (Besides, it’s cool. Mosquitoes in outer space seem rad.) Who Cares?
It’s hard to envision a test tube of half water and half air in outer space • No up, down or sideways. • We think surface tension with the test tube will draw the water to the outside with the air stuck in the middle. Kind of like a water straw. • But unless the astronauts tell us, we won’t know for sure What’s it going to look like? Cooke, Rosa-lee. "Lesson 10: Properties of Water."

Post Offices radiate packages. May kill all mosquitoes. • Potential solution: ship via Fed Ex. • Baker’s yeast consumes oxygen when exposed to water. That could deplete from the volume 2, suffocating all mosquitoes. • Potential solution: use brewer’s yeast and keep it dry with the eggs Volume 1. • Number of mosquitoes limited by amount of air. • Potential solution: increase Volume 2 by limiting amount of formalin in Volume 3. • Unknown unknowns.
