This is the famous experimental complex "Bios-3", which simulates a closed ecosystem. That is, you get in there, the doors close, and you become cut off from the world. This looks like the situation in space. During the experiment, this bunker had everything necessary for a person to live there without going outside: everyone had their own room, there was a kitchen, a toilet, a shower and a special compartment where vegetables were grown. The longest of such experiments lasted six months. Then, 40 years ago, it became a world scientific sensation. Now, Krasnoyarsk scientists continue to improve the biological circulation. They create conditions for people to have a well-established system for the production of air, water and plant food in a confined area in space. "You cannot take everything with you on a long flight. No rocket will lift so many foodstuffs. It is necessary that this food be renewed in a circular process. So, this is one of the main tasks of the biological life support system," says Alexander Tikhomirov, Head of the Laboratory at the Institute of Biophysics, SB RAS. Scientists are studying not only how astronauts can grow different plants and vegetables outside our planet, but also how to make this process more productive. They have even come up with a method for processing organic waste into fertilizers: "We take waste, mix it with hydrogen peroxide, pour it into a reactor vessel and supply alternating current to carbon electrodes. We called it a wet combustion reactor, because the waste is oxidized in the liquid phase," adds Alexander Tikhomirov. Thus, in a few hours, you can get a fertilizer, which is then used to grow plants. This reactor is a unique development of Krasnoyarsk researchers. The scientists also deal with satellite communications. Last year, a laser lithography unit appeared at the Institute of Physics. With its help, scientists create filters which are used at ground-based satellite communication stations, and some of the developments are applied in space satellites. "Each of us has a mobile phone in the pocket. A mobile phone emits a large number of signals at many frequencies. And now, if we start screaming together at the same time, then, for example, in order to hear just one person, I need to somehow filter one of you out to be able to listen to another one. The same situation is observed in space. For me to hear the satellite, I need to filter out all other signals, including those created by modern electronic devices, " says Andrey Leksikov, senior researcher at the Laboratory of Electrodynamics and Microwave Research.
