Uncommon spiral-bound manual entitled "OGO-A, Atlas Space Launch Vehicle Information," prepared by General Dynamic Astronautics and dated September 1964, 19 pages, 9 x 11, containing information relative to NASA's Orbiting Geophysical Observatory program, satellites designed to study the Earth's magnetosphere, with sections as follows: Introduction, Atlas-Agena/OGO-A Statistics, The OGO Program, Atlas Space Launch Vehicle, Atlas Flight, Launch Complex, OGO-A Launch Team, and Current Missions. A portion of the 'Introduction' reads: "The first Orbiting Geophysical Observatory to go into eccentric orbit will be launched by Atlas space launch vehicle 195-D in combination with an Agena upper stage from Cape Kennedy, Fla. The satellite can point sensors at both the sun and the earth and along its own orbital path. Weighing about 1,000 pounds, the spacecraft will carry 20 different experiments, the largest number of scientific experiments for a U.S. satellite to date. The OGO spacecraft will give scientists their first chance to make continuous observations of solar and geophysical phenomena simultaneously. This is expected to yield new evidence of how the erratic behavior of the sun affects the earth." In very good to fine condition, with creasing and a tear to top edge of front cover.
