This book was released on 1961 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: A direct descent is one in which the main descent propulsion system burns continuously from lunar approach to touchdown. The characteristic velocity requirement for direct lunar descents is presented as a function of the landing site location relative to the normal impact point. Results are included for translunar trip times of 60, 75, and 90 hours, for specific impulses representative of both Earth storable and cryogenic propulsion systems, for landing sites located anywhere on the lunar surface, and for ignition thrust-to-Earth weight ratios between 0.12 and 10.0. The data presented are useful in determining approximate performance capability and in evaluating tradeoffs during preliminary mission planning studies.

Available in PDF, EPUB and Kindle. Book excerpt: An analysis of translational maneuvers near the lunar surface is presented. The relative merits of each type of maneuver are discussed on the basis of theoretical fuel consumption and time required for the maneuver. Equations and charts embodying these results are complied herein to facilitate estimation of the fuel and time requirements for various translational maneuvers.

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.

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.
