Wege Zur Raumschiffahrt.

Dedicated “in gratitude” to Thea von Harbou and Fritz Lang, for whom Oberth served as scientific consultant on the 1929 film Frau im Mond (Woman in the Moon). This heavily revised third edition of Die Rakete zu den Planetenräumen debates specific technical objections to Walter Hohmann’s proposed spacecraft cooling methods (Hohmann’s book is also in this collection), and includes four large foldout plates with detailed cutaway diagrams of Oberth’s Modell B rocket design.

Alexander B. Scherschevsky, whose own Die Rakete für Fahrt und Flug is also in the collection, is thanked for proofreading the manuscript.
