An updated version of a title originally published in 1963, this entry in the popular Let’s-Read-and-Find-Out Science series provides an excellent introduction to the moon. The clearly written text discusses what the Apollo astronauts found when they traveled to the moon and touches on the reasons why conditions on Earth and the moon differ. Large, playful illustrations and striking NASA photographs add to the appeal. Recommended titles on related subjects in this series include The Moon Seems to Change and What Makes Day and Night.
