Expedition 11 NASA Science Officer John Phillips and Commander Sergei Krikalev conducted the third and final session with the Renal Stone experiment. The Renal Stone experiment is investigating whether potassium citrate, a proven Earth-based therapy to minimize kidney stone development, can be used as a countermeasure to reduce the risk of kidney stone formation for crewmembers in space.
During this session, Phillips and Krikalev logged everything they ate and drank for three days, and collected urine samples for later return to Earth. This information will give researchers a better understanding of the crew's diet on-orbit which can influence the likelihood of renal stone formation. Astronauts also are at an increased risk of developing kidney stones because urine calcium levels are typically much higher in space.
