NASA Commentator Pat Ryan talks with Dr. Michael Stenger, one of the co-principal investigators of the Fluid Shifts experiment now underway on the International Space Station. Researchers are trying to quantify the amount of fluids that shift to an astronaut’s head and upper body and into and out of cells and blood vessels during an extended period in weightlessness, determine if that increased fluid pressure inside the head and on the back of the eye are responsible for the diminished vision reported by some station crew members after they return to Earth, and investigate potential preventative measures.
