Gravity and the Astronauts (1970) is an example of the non-fiction science books for children that focus on one narrow topic. This is a basic text about gravity using as examples how astronauts cope with the lack of gravity. The illustrations are especially nice in this one.

I am attracted to the humor in the illustrations. Rarely do you see the astronauts smiling as they fly through space. Living in zero and lower gravity looks like fun.
Maybe the images are repetitive but the text explains how gravity affects how you live in space.
I think this is one of the few drawings I have ever seen of an astronaut sleeping.
The text reminds the reader that everything is changed if you don't have gravity.
A gentle and fun book that feels like going to space might feel more like a vacation than real work. I hope your upcoming summer has as much relaxation in it as these astronauts seems to find on their way to the moon.
