Published by Hachette in 1982 for the twenty-fifth anniversary of Sputnik 1, this volume in the "Encyclopédie Hachette" series offers a complete survey of the first quarter-century of spaceflight. It is organised in three parts: the people (pioneers, the Peenemünde engineers, astronauts and cosmonauts), the means (rockets, satellites and orbits, launch sites, spacecraft and probes), and the results and prospects (space medicine, Earth sciences, application and military satellites, space law). Lavishly illustrated and packed with data tables, it covers the American, Soviet, European, French, Japanese, Chinese and Indian programmes, closing with a chronology of key dates from 1957 to 1982.
