The why's and how's of space travel are demystified in this kid-friendly reference guide that encourages children to ponder humankind's future in space. The questions, generated by students in kindergarten through high school, address issues--ranging from animals, asteroids, black holes, space exploration, and sleeping in zero gravity--that are divided into 85 distinct subject categories. Easy-to-understand explanations to queries such as "What does space smell like?" are provided by internationally recognized experts that include NASA engineers, former astronauts, astronomy professors, and aerospace instructors. Illustrations appear both in the book and on an accompanying CD-ROM, making this a useful classroom activity guide or tool for child-parent discovery.
