Technical Letter: Astrogeology-3 Preliminary Scientific Mission Profiles For The First Seven Apollo Missions

The National Aeronautics and Space Administration plans to land two astronauts on the Moon as a part of the Apollo Space Program. The questions arise: What should the astronauts do on the surface and what information should they gather? This report proposes answers to these questions by describing a possible series of scientific activities, or mission profiles, to be performed by the astronauts o

Manned Lunar Exploration Investigations Plan Of Research, And Work Plan And Operating Budget. Fiscal Years 1965-1966

The National Aeronautics and Space Administration, working with members of the scientific community, has determined that early manned lunar exploration will be oriented primarily to investigations in the geosciences. Exploration by man on the lunar surface will, therefore be geological, geophysical, geochemical, geochemical, and surveying in nature, and will be directed to the physical and chemica

Schedule and Outline of Courses in Geology Astronaut Training Program

Outline and schedule of geology training courses provided by the USGS Astronaut training program. Training topics include, but are not limited to, lunar and terrestrial geology, the rock cycle, impact processes, rock and mineral identification, lunar and terrestrial geophysics, and geologic mapping. This outline is dated January 8, 1964.

Technical Letter: NTS-79 Guidebook For Field Trips To The Nevada Test Site

In several respects the Nevada Test Site is located in an area that is especially interesting geologically. It lies along the projected trend of the Walker Lane and the Las Vegas Valley Shear Zone (Locke and others, 1940; Longwell, 1960), one of the major crustal features of the Basin-Range province. The shear zone itself, however, may not continue through the Test Site in a simple way (Burchfiel,

Technical Letter: Astrogeology-12, Time and Motions Required to Perform an Active Seismic Experiment Proposed for the First Apollo Landing

At the suggestion of the Planetology Subcommittee of the Space Sciences Steering Committee, an active engineering seismic experiment originally proposed by J. S. Watkins, J. Cl. De Bremaecker, and M. F. Kane was incorporated into the Early Apollo Active Seismic Experiment originally proposed by R. L. Kovach . J. S. Watkins was made co-experimenter for the Early Apollo Active Seismic Experiment wit

Annual Report Investigation Of In Situ Physical Properties Of Surface And Subsurface Site Materials By Engineering Geophysical Techniques Project Part 1

This report includes the first substantive body of in situ density, bearing strength, shear strength, and moisture content data measured by Project personnel. Emphasis in this fiscal year's measurements was on low-density materials since available data suggest that the upper meter or so of the lunar surface consists of low-density material.

Technical Letter: Astrogeology-11 Apollo Applications Program Investigations Field Test 3

Apollo Applications Program (AAP) Test 3 was held in Flagstaff, Arizona, as an initial feasibility study of rock thin-section preparation and remote television monitoring of the microscopic image, for possible use on AAP missions. During the 18 hours of actual test operations 38 thin sections were prepared. Of these, 25 were examined with a petrographic microscope with a television link to the Co

Apollo Science Program, Mission Profile Study

Details of field exercises to assess the readiness of astronauts to perform geologic investigations on the lunar surface. They include landscape description, geologic mapping, mobile traverse descriptions, impact crater description, depression description, and detailed mapping.

Technical Letter: Astrogeology 6: Manned Lunar Exploration Investigations Report Apollo Field Operations Test II

Systems and shirt-sleeve operations tests were conducted at the Bonito Flow test site from April 5 through April 9. The tests provided the opportunity to evaluate field test logistics, systems compatibility, systems operation, and geological field and control center operations. This report summarizes the evaluations that bear on the potential usefulness of systems and operations.

Experiment Description Document - Surveyor Lunar Roving Vehicle Topographic Mapping

This document is part of the Functional Specifications for the Topographic Mapping Experiment to be carried out by the Surveyor Lunar Roving Vehicle. It includes a description of the experiment along with the accuracies required for meaningful results.

Astronaut Lecture of H. J. Moore

The main idea behind this slide presentation is to develope a general philosophy on: 1) lunar impact cratering processes, 2) characteristics of impact craters and ejecta as a function of target material and, size, 3) the effects of layered targets on impact crater morphology, and 4) illustration of the above for lunar sites.
