The Moon Rocket.

A popular account of the British Interplanetary Society’s lunar-ship studies. It carries an introduction by Prof. A. M. Low, who calls it “a very important book.”

Sixteen chapters move from the history of flight and the case for the rocket, through gravity, speed and acceleration, fuels and motors, to the “stepping-stones” of space, two chapters on the B.I.S. rocket, and then the journey itself: thin air, the void, the Moon and the return to Earth. Appendices give answers to the puzzles posed in the text and a table for reference. Illustrations include a Max Valier rocket-car frontispiece, American rocket-society test photographs (an experimental rocket, a liquid-fuel test, the Greenwood Lake rocket-plane flight), John Shesta’s rocket-motor diagram, and diagrams of the B.I.S. spaceship.

It complements Harry Harper’s Dawn of the Space Age of the same year (also in this catalog), likewise approved by the B.I.S. Two copies in the collection.
