If you were told that you could be paid to spend the day doing nothing? This is what NASA offers volunteers for the modest sum of 16,500 euros! As part of a research project in partnership with the European Space Agency (ESA), this entity wants to explore the effects of artificial gravity on the human body. Relayed by our colleagues from The Independent , here are the details of an initiative that will surely catch the attention of the public!
It is through an unprecedented experience that NASA, a world-renowned government agency, will allow ordinary people to pass through its doors to contribute to science! Wishing to extend its research to Earth to provide better living conditions for its astronauts, this institution does not hesitate to offer a significant salary to those interested in the project . Let’s take a closer look at this one …
Objective of the project
In collaboration with the ASE and DLR (German Center for Aeronautics and Astronautics), NASA is offering volunteers a modest sum of 16,500 euros to lie on a bed for two months. The AGBRESA (Artificial Gravity Bed Rest Study) project aims to evaluate changes in the body when astronauts are in a context where gravity is absent. Through beds at Envihab , a research center operated by DLR’s The Institute for Aerospace Medicine, researchers hope to identify new techniques to annihilate the effects of weightlessness on a human body accustomed to gravity.
The total duration of the project is 89 days, of which 60 will have to be dedicated to lying on a bed, 5 days to familiarization with the environment, 14 days to rest and the remaining 8 to reacclimatation to the conditions of terrestrial life. In order to put this initiative into practice, the agencies are looking for 24 German-speaking volunteers (12 men and 12 women) aged between 24 and 55 years old. The AGBRESA project will take place in two stages. The first round of tests began on March 25 and will be followed by at least a second in September.
Progress of the experiment
During the 60 days of the test, the volunteers will lie in beds inclined at 6 degrees to obtain an accurate representation of the movements of body fluids. Any activity during the experiment must be carried out under the same conditions. In order to evaluate the different reactions of the participants, the volunteers will be divided into two groups.
One of them will have to undergo the centrifuge test with close to 30 rotations per minute in order to allow the scientists to compare the results with the rest of the group, especially in terms of their equilibrium, cognitive functions, cardiovascular function and state of their muscles.
As Jennifer Ngo-Anh, Team Leader of the Human Exploration and Robotics Division explains, this series of tests is designed to better understand the problems of muscle atrophy, isolation and radiation that are part of space borne by astronauts.

The effects of weightlessness on the human body
Considered by many to be an amazing and unusual experience, weightlessness is not without risk to the human body. Indeed, these are often relegated to the background because the public focuses more on the originality of this phenomenon rather than its physical impact. On the other hand, for astronauts, astronauts can create many constraints that are continually subject to scientific tests in order to be regulated, as evidenced by the NASA initiative.
Indeed, weightlessness greatly affects the body, especially in the bones and muscles . As the government agency explains , atrophy of limbs requires daily physical activity to slow down the deterioration of the limbs, since an astronaut could lose 1% of his bone mass in just one month! Compared with the elderly who would lose 1 to 1.5% of their mass in one year; The difference is size.
In addition, the risks affect many areas, including the movement of fluids within the body. Often compressed in the brain, they would be able to affect the vision of the astronaut and would even change the shape of his eyes!
