This issue of Life includes “Apollo’s Leap for the Moon” by reporter Loudon Wainwright, “Moon Shot—Spectacle at the Cape” and “Nixon’s First Six Months” as well as and photographs of the astronauts’ wives.

Autograph Letter Signed to C. C. Maxwell. No place, Sept. 26, 1857
In this wonderful letter Faraday discusses the famous experiment in which Galileo is said to have dropped spheres of different masses to show that their time of descent was independent of their masses. Though said by some to have been a thought experiment, this was one of the most famous demonstrations in the history of science. The experiment disproved Aristotle’s theory of gravity and helped usher in the era of modern science.
