Women Wrap Up 60 Days of Simulated Spaceflight
Dec 9, 2005 - Volunteers with the Women International Space Simulation for Exploration (WISE) campaign have wrapped up 60 days of bedrest, simulating the effects of weightlessness on the human body. The 24 women spent two months in medical beds which were slightly tilted head down. The data collected during the study will help prepare astronauts for long-duration spaceflight, but it'll also help researchers working on medical problems here on Earth too. (Full Story)
