A look at how the US astronauts are chosen and trained, padded with a short history of the space program. The authors mention some simulation techniques and devices (e.g., the ""Vomit Comet"" and the Weightless Environment Training Facility), as well as astronaut specialization and gear. Browsers will be attracted by the bright color photos of space-bound men and women floating, parachuting, working with equipment, and obviously having a ball. This may turn the thoughts of younger or less practiced middle readers toward careers in astronautics, but Long's The Astronaut Training Book for Kids (p. 266/C-46) addresses its audience more directly and covers the subject in greater detail. Reading and address lists appended. Index.
