Published by Julliard in 1967, Demain l'espace is Albert Ducrocq's major encyclopaedic synthesis, written at the peak of his influence as France's leading space science communicator. In fourteen chapters and 405 pages, the work surveys the full contemporary space landscape: Earth as seen from space (Gagarin, living maps), telecommunications satellites (Intelsat, Molniya, Early Bird), interplanetary physics, robotic lunar exploration (Luna 5–9), the robots-versus-humans debate, space biology (Laika, Cosmos-110), ongoing programmes (Mercury, Gemini, Apollo in preparation, Voskhod), industrial applications and space geography. The final chapter takes an original geopolitical stance: Europe's failure to act (ELDO), space law and international cooperation. Fourteen tables and a list of figures complete the volume.
