This, the second volume of the Apollo Spacecraft Chronology, takes up the story where the first left off, in November 1962. The first volume dealt with the birth of the Apollo Program and traced its early development. The second concerns its teenage period, up to September 30, 1964. By late 1962 the broad conceptual design of the Apollo spacecraft and the Apollo lunar landing mission was complete. The Administrator formally advised the President of the United States on December 10 that NASA had selected lunar orbit rendezvous over direct ascent and earth orbit rendezvous as the mode for landing on the moon. All major spacecraft contractors had been selected; detailed system design and early developmental testing were under way.
