Russian scientists work on protecting manned space stations on the Moon, Mars and other planets of the Solar system, by means of self-pressuring systems.
      
      Surface of the Moon, Mars and other planets of the Solar system is intensively bombarded by micro-meteorites and space debris, and that is why space stations need protection.
      
      Protective screens are currently reaching technical frontiers due to weight restrictions, so scientists suggest a new protection systems, based upon quick and effective restoration of station’s air tightness in case of a puncture. Researchers suggest three possible techniques for puncture elimination: a plug, a liquid sealer, or a combination of first two techniques – a self-pressuring system.
