Not so long ago, representatives of the European Space Agency began work on two long-space projects. These projects will be carried out as part of the ESA Concurrent Design Facility program, which aims to investigate the possibility of hibernating (roughly speaking deep sleep with a slowdown in physiological function of the body) of astronauts during space missions. Especially on flights to Mars and possibly other planets of the solar system and possibly beyond.
How do I fly to Mars?
Engineers of the European Space Agency propose to use rest capsules. In addition, the concepts of cabins and crew spaceships for long-haul flights were also presented. Even with the most modern ship and engine models, a flight to Mars takes several months. And even for trained professionals, this is not only a major burden from the point of view of the nervous system, because in space there is essentially nothing to do, and closed spaces are not optimally reflected in the emotional state. But also from a physiological point of view, because all the time it is necessary to absorb nutrients and to satisfy physiological needs.
The way out of this situation is the hibernation mode, long proposed by science fiction writers, where a person does not need much space and food needs are minimized. Using hibernation mode allows the use of smaller spaceships for long haul flights and also requires less fuel. – say representatives of the European Space Agency.
The Space Agency's new project should include individual capsules in which all crewmembers will be present during the flight. In addition, tiny cabins are available for the awake crew members as someone must monitor the condition of the ship and the health of the sleeping astronauts. Would you like to go to Mars?

After the project, hibernation capsules have a soft inner shell that darkens while a person is in it. In addition, the capsules have a system for protection against cosmic radiation. And they can also be used as a place to sleep for the "normal" version of sleep after the pioneers reach the Red Planet. It is also worth noting that for so long a period of "inactivity" a certain amount of muscle and bone mass is atrophying. According to preliminary estimates, the rehabilitation time after waking should be about 21 days, according to researchers.
Automatic artificial intelligence systems are also being used to keep the spacecraft in working order, but details of this have not yet been announced. In addition, representatives of the European Space Agency point out that these projects are only the beginning of their journey. And by the time they're done, more than a dozen years pass. In this regard, NASA's forecasts of landing on Mars seem already too optimistic in the 2030s. On the other hand, who knows which technologies Americans now have in the cover? Maybe they are ahead of what they are cooking in the European Space Agency.
