I guess it will be "moon week" for me. In 7 days is the 40th anniversary of a human's first steps on the moon. Here is one of my favorites just for its cover.
Lewis, Claudia. Illustrated by Weisgard, Leonard. When I Go to the Moon. New York: Macmillan Co. (28 p.) 26 cm.
A basic book about viewing the Earth from the point of view of a boy standing on the Moon. A beautiful children book filled with loose impressionistic paintings of the Earth in space, and the surface of the Moon. This book is not so much about space flight, with only one picture of a rocket but rather viewing the Earth as a whole, seeing your place on Earth from a new point of view. See 1967 reprint.
