Gr 3-6Space discusses international space technology of today and forecasts its future. The book begins with the launching of Sputnik in 1957 and ends with predictions for the next 20 to 30 years. Sharp, dramatic charts and illustrations in color occupy at least half of each page; each picture is accompanied by a descriptive paragraph. Short, readable two-page chapters on rockets, space probes, mission control and other timely topics are scattered among the pages. Included at the back of the book are a glossary, an index and a date line, all of which are helpful but incomplete. In the chapter on space today, little mention is made of Skylab or Spacelab, but most of the other chapters give good coverage to the United States' program. This new book packs a lot of information into a thin, bright package. It will appeal to youngsters who are just beginning to ``explore'' space; others will enjoy the illustrative material.
