Published in June 1958 in the wake of the first Sputniks, this popular science work traces the projected conquest of the Moon from ancient myths to contemporary rocket programmes. Robert Lechêne, a science journalist at L'Humanité Dimanche, guides general readers through lunar astronomy, the conditions of spaceflight, and the challenges of survival in weightlessness. Drawing on the work of French specialists (Alexandre Ananoff, Albert Ducrocq) the book covers its subject across nineteen chapters spanning lunar astronomy, the history of rocketry, orbital mechanics, and the prospects of lunar colonisation.
