The film is based on the loss of contact with the Soviet Union's "Salute VII" space station in 1985, and tells the story of two astronauts repairing the space station. During this period, I experienced difficulties in docking the spacecraft with the high-speed rotating space station, freezing inside the space station, melting ice and drying, explosions, and the ordeal of astronauts going out to repair sensors. The most worrying is the lack of oxygen, only one person can be brought back to Earth, and the space station must be bombed to prevent the United States from stealing. The most classic line came "If I go back alone, how can I explain to my child and how to explain to your child", so the two of them dropped the sensor with a hammer without air and strength. Hard shell, solar power back on, power system restored, space station restored.
The wisdom, bravery, and perseverance of human beings are all admirable. People with great missions.
