Imagine lying in bed for weeks without sleeping I stand up – and pay me great for your troubles.
What sounds like a dream job for some is in fact the creation of a new experiment conducted by NASA and the European Space Agency. The study, which began Monday in Cologne, Germany, aims to assess the health effects of long-term space flight by limiting the movements of participants for two months. the study will also explore the potential benefits of artificial gravity, helping to keep astronauts healthy on missions to Mars and other distant destinations. This is the first such collaboration between space agencies and the first one to use a cosmic "human centrifuge" to create artificial gravity.
The study "offers researchers across Europe and the United States the opportunity to work together and jointly to acquire as much scientific knowledge as possible on human physiology," said Hansyord Dithus, a board member of the German Aerospace Research Center
. takes place in the center of envihab in Cologne, where participants – 12 men and 12 women – will spend 60 consecutive days in bed during the entire 89-day study, which includes extra time for preparation and recovery. For their time they will be paid € 16,500.
More than half a century of human space flight has shown that the microgravity environment of space causes the human body to undergo drastic and potentially dangerous changes. Without the gravity of the Earth to lower things, body fluids glide up to gather in the chest and head, and the bones and muscles spill. of their beds: envihab all the time of the study
But lying in bed is not exactly a walk in the park. The beds of participants are slightly sloping downwards to encourage fluid to collect in the upper body. And to mimic the effects of microgravity on muscles, bones and tendons, participants are required to minimize every movement. That means at least one shoulder of the mattress all the time.
While lying in bed, some of the men and women will endure daily sessions in a "human centrifuge" that rotates like a carousel to create forces that simulate gravity. When they do not rotate for science, they will be subjected to tests of cognitive function, blood flow, and muscle biopsy.
If everything sounds good to you, you're lucky. The German aerospace center says the slots are still open for the second phase of the experiment, which begins in September.
