NASA says this movie has the most realistic rocket science

When people think of realistic sci-fi media, their minds might go to a TV show like For All Mankind, which meticulously charts out how the world would be different had the United States and the Soviet Union never stopped running the space race, doing its best to take the science seriously. They probably wouldn’t think of a century-old silent movie where a group of characters travel to the Moon only to find that the atmosphere is breathable.
