I love this image of the conquest of Mars (or wherever). Sometime I'll create a posting of all the different images of a U.S. flag claiming the Moon, Mars, etc. We are used to calling it propaganda when we see an image of a soviet flag claiming the moon (or currently a Chinese flag) but this reoccurring image was presented to children in many of the U.S. books of the time.
The text focuses on how rockets work and the future uses of rockets. It also includes a chapter on nuclear powered ion engines.
