Now NASA and EAS are in a joint study to learn how zero gravity can improve health of astronauts when they are on long term missions.
Currently, astronauts on the International Space Station do several hours of exercises a day to fight off the negative results of living in almost weightless conditions, which tend to breakdown muscles and bones.
Scientists at the German Aerospace Center have been commissioned by the European Space Agency and NASA to conduct a study on how they can counteract the effect of weightlessness.
"We accompany you on your mission as a terrestrial astronaut". ESA claim it is integral in understanding the damage that may be caused by weightlessness, cosmic radiation, isolation and spatial restrictions.
No matter the way you see the dream job for you, you must admit that you would prefer getting paid to lounge around in bed for 60 days.
The pro-sleepers are replicating long-term spaceflight and its effect on the body, the space agency says. For this activity, NASA and ESA want a crew of volunteers so the potential benefits of artificial gravity can be tested on them.
Once a day, select participants will be taken for a spin at the Center's short-arm centrifuge in order to pump blood back toward their legs.
If the researchers manage to find a technique to build artificial gravity in space, it would be a breakthrough invention and will help the astronauts deal with the after-effects of staying in space for a long time.
The scientists are looking for healthy women between the ages of 24 and 55 years who are non-smokers to participate in the study, according to the study's website. Once the two months of bed rest is complete, participants will be required to stay an additional 29 days for acclimation and supervised recovery.
