Astronaut's imagination

I have always had a special respect for the vast universe. Perhaps because of its depth, unpredictable vastness, and unfathomable depth, I always had unlimited imagination about it when I was a child. I really like movies about the universe. In the movie, I have seen astronauts accidentally self-destructing in the vast universe. Because a slight malfunction can easily put their lives in danger, so astronauts are human beings exploring the universe. Warrior, very respectable!
