Aboard the International Space Station, Expedition 32 Flight Engineer Sunita Williams, a Massachusetts native, discussed her activities aboard the orbital laboratory in a series of in-flight interviews July 31 with WCAI Radio, the National Public Radio affiliate in Woods Hole, Mass., and CNN's Sanjay Gupta. Gupta will participate in a triathlon competition on Earth in August while Williams hopes to emulate that in orbit. The two discussed the effects of weightlessness on physical fitness for astronauts who are living in space for long periods of time.
