Pressure control and support technology for spacecraft space exploration

Abstract As a top-level requirement for ensuring the exploration work inside and outside the spacecraft, the cabin pressure control technology of the spacecraft ensures the safety of astronauts and is one of the core systems for maintaining astronaut space exploration. This article introduces the pressure control and support technology for space environment exploration and constructs a cabin pressure control model. Through simulation verification, the constructed model meets the requirements of spacecraft cabin pressure control, and can effectively save the extravehicular activity air source. This technology can provide a reference for pressure support systems for manned space stations, Mars, and lunar exploration spacecraft.
