10 questions and 4 activities to help children understand why humans want to explore space, and how they've gone about it.

A book to answer children's questions about space exploration: how and why do we go to space? Why don't satellites fall down on our heads? Why do astronauts wear spacesuits? What do they do up there in the International Space Station? Can I go to space one day? In the activities section, make rockets powered by a balloon or water, or play with gravity and centrifugal force.
