Learn about the harmful health effects of living in zero gravity and a potential solution in this video from NOVA scienceNOW: "Can We Make It to Mars?" NASA astronaut Jerry Linenger describes the bone and muscle loss he experienced during his five-month stay aboard the Russian Space Station. Host Neil deGrasse Tyson visits neurophysiologist Janna Kaplan to learn how artificial gravity could mitigate the risks of space travel. The rotation of a spinning room creates a centrifugal force that pushes the body against the wall, simulating gravity; if such a room were onboard a spacecraft, it could help astronauts preserve bone and muscle mass.
This video is available in both English and Spanish audio, along with corresponding closed captions.
