The short-arm centrifuge at the German Aerospace Center's (DLR) :envihab facility in Cologne, Germany will be used during the first joint long-term bedrest rest study commissioned by ESA and US space agency NASA to investigate the potential of artificial gravity in mitigating the effects of spaceflight. The study begins on 25 March 2019 and will run for 89 days. Test subjects will need remain in beds with the head end tilted 6 degrees below horizontal for 60 of these days to simulate the microgravity of space.
