Space Puzzles: Curious Questions and Answers About the Solar System (1971)

A rather different space book today,  It is mostly text outlining (and teaching about) spaceflight and the solar system. Martin Gardner was famous for his puzzle column in Scientific American but I was unaware of his children's books.

Space Puzzles: Curious Questions and Answers About the Solar System, Martin Gardner. Illustrated by Ted Schroeder. New York : Simon and Schuster. (95 pp.) 1971 24 cm. 

So I will share a few of the 41 questions posed in the book.

 For this last question I will share the answer but I am also astonished by the violent illustration in a children's book. How many possible space careers did it end?
