A common error of pulp cover artwork is rendering Earth as a cloudless planet as shown in the above painting. The scale of Earth and the Sun with respect to the Moon scene is much too great. Additionally, the lunar terrain is depicted as much too jagged based on findings of the Surveyor lunar probes and Apollo manned landings. The agility of the "jumping-jack" astronauts is an exaggeration based on the restrictiveness of pressurized space suits. Would an astronaut be bounding about in a pressurized suit with a sharp pick, shovel, and an axe attached to his belt? Should he trip on a moon rock, any of his tools could puncture the space suit ending his life quickly. In defense of the artist, it appears that the suits are armour-like in design such that puncturing them would be more difficult than puncturing those worn by the Apollo astronauts.
