Proposal Accepted!!!
The 2009-2010 ZeroG Team proposal has been accepted! This year's experiment studies ultrasonic liquid cooling and the effects of varying frequency and gravity. By creating small perturbation bubbles directly on the heat source, heat can be more effectively carried away from the component. This is a technique shown to augment standard liquid cooling but has yet to be tested in a variable gravity environment. The experiment will be flown on a C-9 at the Johnson Space Center in Houston, TX during the scheduled flight week of June 17-26. Email zerog@rso.wisc.edu if you have any questions. The University of Wisconsin-Madison's ZeroG Team participates
in NASA's Reduced Gravity Student Flight
Opportunities Program. In this program, students from across the nation design experiments
to be performed in a microgravity environment. The student teams write and submit proposals to NASA,
and selected teams are given the opportuntity to conduct 
their experiment on board NASA's C-9B
Weightless Wonder (pictured, photo credit: NASA). This plane can achieve microgravity
(zero-g) by flying a parabolic path, which is the path taken by a free falling object. When the plane goes
over the top of the parabola, it is in a free-fall and passengers inside experience about
23 seconds of microgravity. The plane flies approximately 30 parabolas
so students can run many trials of their experiment.
