Past Ground Based Research
The UCSD NASA Lab has conducted its ground research both in its laboratories in San Diego, CA as well as at research facilities that aren't actually on the ground.
Frequently this research has been conducted aboard NASA's KC-135 microgravity research plane, commonly referred to as the "Vomit Comet".
During these experiments the researchers take turns acting as the subjects to optimize the scientific return of the flight. In this way there are no wasted bodies aboard the plane. Both the bolus experiment and the aerosol deposition experiment were conducted aboard the KC-135.
Occasionally, UCSD researchers fly to Europe to collaborate with colleagues from the Biomedical Physics Laboratory, Université Libre de Bruxelles, Brussels, Belgium. They have also collaborated in experiments performed aboard the ESA Airbus A-300 microgravity plane operated by Novespace out of the Bordeaux-Mérignac International Airport.
