capsuleThe space capsule, also known as the cosmic capsule, was the place where astronauts worked and lived after the spacecraft entered orbit. It was also a large-scale comprehensive space medical engineering simulation equipment that simulated the special environmental conditions of space on the ground (such as high vacuum, strong solar radiation, and "heat sink" or "cold black", etc.).
In terms of function, it could be used to study the reaction and working ability of astronauts in space, as well as the relationship between people, equipment, and the space environment. It could also test and measure the performance and status of the entire spacecraft and related components and systems. It consisted of a cabin, a vacuum pumping system, a solar radiation system, a heating system, a liquid nitrogen (helium) cooling system, an emergency repressurization system, a main console, a data processing system, and related supporting facilities.
In terms of manned space flight, on April 12, 1961, Gagalin entered Earth's orbit on the Vostok spacecraft, opening the journey of manned space technology. On October 15, 2003, China's first manned spacecraft, Shenzhou V, was successfully launched. On the morning of October 31,2023, the orbital module and the return module of the Shenzhou 16 manned spacecraft were successfully separated.
In the construction of China's space station, the Ask the Sky experiment module and the Dream Sky experiment module were important components. The Sky-Seeking Pod was 17.9 meters long, which was larger than the Sky-Harmony Core Pod. The Dream Heaven Cabin was almost the same length as the Heaven Seeking Cabin, but the pillar section was longer. Its volume, internal space, and weight exceeded the Heaven Seeking Cabin and the Heaven Seeking Cabin. It was the largest single cabin section among the three cabins. It was composed of four parts: a pressure-sealed cabin (work cabin), a cargo airlock cabin, a load cabin, and a resource cabin. The cargo airlock cabin had an innovative design, and it also came with multiple large-scale space exposure experimental platforms. It was more efficient and cheaper. The Dream Sky Cabin was estimated to be launched in October 2022 by the Long March V B Yao 4 rocket to dock with the space station assembly. It was likely to use a fast docking method (docking was completed three and a half hours after launch).
In addition, there was also a civilian space capsule, such as the Sichuan Starry Summer space capsule. It was 9 meters long, 3.2 meters wide, and 3.2 meters high. It integrated environmental protection concepts. The outer shell was made of aviation aluminum, and the main body was made of Galvanized Steel. It was made of PUBG foam technology for heat insulation and sound insulation. The interior was equipped with a smart home system, bedroom, wet and dry separation bathroom, etc. It supported custom design.
