Front cover: The operational era of Project Gemini began on April 8, 1964 with the launch of the unmanned Gemini 1 from Pad 19, Cape Kennedy, Florida, atop the two-stage Titan II launch vehicle (right). This was followed less than one year later by the first manned flight, Gemini 3, nicknamed ‘Molly Brown’ by Command Pilot Virgil I ‘Gus’ Grissom and Pilot John W. Young. Young is seen here striding towards the elevator at the launch pad to take up his place in the spacecraft on March 23, 1965 (left). (Courtesy Ed Hengeveld). Back cover: (Right) Between Gemini 1 and Gemini 3, the unmanned Gemini 2 flew a sub-orbital test of the spacecraft’s heat shield in January 1965, clearing the way for manned operations. Here, the spacecraft’s re-entry module is seen on the recovery carrier after being retrieved from the ocean (Courtesy Ed Hengeveld). (Left) The cover for the next book in this series covering the four-day mission of Gemini 4 in June 1965, which included America’s first experience of extravehicular activity (more commonly known as a spacewalk).
