It sounds like the best job in the world - stay in bed for two months and do nothing. But 12 women are doing just that, all in the name of space travel research.
The European Space Agency, in conjunction with NASA and the Canadian equivalent, is running a 60-day study to discover the effects of weightlessness on female astronauts. The majority of existing data is about the effects on male bodies as most astronauts are men. However, with longer trips planned to Mars and an increase in female crew, more information is needed about how their bodies react to months of space travel. Now the Women International Space Simulation for Exploration study has put the volunteers in bed with their feet slightly raised above their heads to mimic the effects of a zero-gravity environment. The women have to eat, sleep, wash and go to the loo in the same position so scientists can monitor the physical and psychological effects on their bodies and brains. The most common impact of space travel on human bodies is loss of muscle and bone, particularly in the legs and feet. Many astronauts are too weak to walk when they return to Earth. Once the women have finished the study, they will return to the space clinic at the Rangueil hospital in Toulouse, France for up to three years for check-ups. The only British woman in the study, Morag, told The Guardian newspaper that her friends thought she was crazy for applying to the job advert. "When I get out, I imagine I won't be able to walk too well at first," she said. "People say we're guinea pigs, but if we are, we're happy guinea pigs."
