The contents of this work was prepared for the National Aeronautics and Space Administration by the staff of the Jet Propulsion Laboratory. Foreword by W. H. Pickering. This book is a brief record of the Mariner Project to date and is designed to explain in general terms the preliminary conclusions. Actually, it will be months or years before all of the data from Mariner II have been completely analyzed. The most important data were the measurements made in the vicinity of the planet Venus, but it should also be noted that many weeks of interplanetary environmental measurements have given us new insight into some of the basic physical phenomena of the solar system. The Mariner II spacecraft to Venus not only looks at Venus but gives space scientists and engineers information helpful in a wide variety of space ventures. A project such as Mariner II is first a vast engineering task. The operations required to carry out the mission must be understood and performed with precision. A successful mission requires every member of the entire project team to do his task perfectly. Whether it be the error of a designer, mechanic, mathematician, technician, operator, or test engineerâ"a single mistake, or a faulty piece of workmanship, may cause the failure of the mission. The Jet Propulsion Laboratory was heavily supported by industrial contractors building many of the subassemblies of the spacecraft, by scientists planning and designing the scientific experiments, and by the Air Force which supplied the launching rockets. Mariner II is only a prelude to NASA's program of unmanned missions to the planets. Missions to Mars as well as Venus will be carried out.…
