This book was released on 1962 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: "An investigation has been made of some of the problems associated with abort from landing and return to an orbiting vehicle in a 50-mile lunar orbit. For this study the landing module was considered capable of direct return to the orbiting vehicle from a hovering position at the lunar surface. The investigation was divided into two parts, an analytical study and a simulation study. The results of the analytical study indicate that, for an economical return to the orbiting vehicle, the landing maneuver should be chosen such that the orbiting vehicle is almost directly above the landing module at the touchdown point. This requirement places limitations on the angular travel of the landing vehicle around the moon prior to touchdown. Results of the simulation study indicate that a pilot can control the abort maneuver by using visual information."--Summary.

This book was released on 1971 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: An Earth-return mode for interplanetary spacecraft via hyperbolic rendezvous is described. In this mode an orbit-to-orbit shuttle leaves a circular Earth orbit, performs a rendezvous with a returning interplanetary spacecraft as it approaches Earth on a hyperbolic trajectory, docks and performs desired transfers, and deboosts back into a circular Earth orbit while the spacecraft continues on its hyperbolic path. Two basic flight modes are proposed, and the equations for analyzing the maneuvers are derived. The initial mass in Earth orbit required fora rendezvous system utilizing chemical or nuclear propulsion compares favorably with the initial masses in Earth orbit chargeable to transport of some conventional Earth-return systems to a target planet and back. In addition, the maneuver has considerable merit as a backup and rescue system. For typical missions, orbit-to-orbit shuttles having initial masses in Earth orbit of up to 500 000 kg are required.

Available in PDF, EPUB and Kindle. Book excerpt: Progress in Astronautics and Rocketry, Volume 10: Technology of Lunar Exploration is an overview of the technical base of the lunar exploration problem. This volume is organized into six sections encompassing 35 that follow the various stages of accomplishment of a lunar mission, involving landing on or orbiting the moon and returning to the earth. The first section is devoted to the problem of trying to define the lunar environment, emphasizing the theories of the lunar environment as it relates to the internal structure of the moon. This section also describes some activities to achieve a reasonable theory concerning what might be encountered in some of the previous lunar flight programs. The second section explores the problems associated with the limitations imposed upon lunar missions by the launch vehicles and launching facilities. The third section looks at the spacecraft systems and techniques required for lunar missions, particularly the technology and specific subsystems in relation to the requirements imposed by specific lunar mission objectives. The fourth section deals with the actual landing on the moon and the subsequent surface operations, while the fifth section covers the lunar launch, return, flight re-entry, and subsequent landing on earth. The sixth section reports the status of the projects that represent the United States lunar exploration program, which integrates the technologies developed in the preceding sections into certain discrete projects.
