I didn't know that the Soviet Union was the first to realize human spacewalking in the Cold War. In the movie, the male protagonist staged several reversals due to his love for adventure. I don't know how history played out. But the movie does perfectly explain the difficulty of human spacewalking, from the training of astronauts, the design of space suits, and the testing and experiments of spacecraft, and finally sending astronauts to the sky, everything is fighting against fate.
Maybe people must stick to their dreams in good times (at that time, it was indeed a dream for humans to walk in space), and in adversity, people must have perseverance, courage, dare to fight, and not give up any opportunities that bring a turning point to themselves.
