Technical Letter: Astrogeology 27, Apollo Applications Program Field Test 5

Apollo Applications Program Field Test 5 was held March 14-18, 1966, in the Hopi Buttes area, Arizona. The objectives of the test were to 1) evaluate techniques of field checking a moderately complex photogeologic map--techniques potentially useful for lunar geologic exploration; 2) test the feasibility of using a vehicle mounted magnetometer and applying the magnetometer results to real time geol

Technical Letter: Astrogeology 28, Task Analysis Of Shirtsleeve Geologic Methods For The Apollo Applications Program Test AAP-8

A shirtsleeve test of geologic reconnaissance methods applicable to lunar surface exploration was conducted using astronauts as subjects. The task analysis objective was to determine the efficiency of a 2-man traverse. A table summarizes the full-day traverse, and a process chart (time line) is included in the report. It was concluded that two astronauts can complement each other's work with littl

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.

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

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

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

Technical Letter: Astrogeology-8 Apollo Extension Systems Field Test I

A field test held in the Hopi Buttes, Arizona, was planned to test geological, geophysical, and analytical operations and instruments that are of potential use in Apollo Extension Systems lunar surface missions. The test was conducted under "shirt-sleeve" conditions, but potentially useful methods of recording and compiling information during lunar exploration were employed. The test showed that b

Technical Letter: Astrogeology-9 Early Apollo Investigations Field Test 5

When the Apollo astronauts land on the Moon, their precise location will not be known. The real-time geologic mapping planned for the first mission could best be done if the exact position of the landing site were determined. The astronauts may have to find their position, with or without assistance from the Earth-based scientific mission center, before leaving the Lunar Module (LM), and the less

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,

United States Government Memorandum: Radio Procedures

These suggestions are largely a result of two closely allied factors: first, a tape recording--either direct or one made via radio--should enable· a field geologist to record many more observations per unit time than can be made in a notebook. The observations should be to the point, but there is no reason for them to be cryptic and so potentially ambiguous to another person. Second, persons in a

Quaternary deposits of the 9-county San Francisco Bay Region: an areally continuous digital map database prepared from Knudsen and others (2000) and Witter and others (2006)

This digital map database provides an areally continuous representation of the Quaternary surficial deposits of the San Francisco Bay region merged from the database files from Knudsen and others (2000) and Witter and others (2006). The more detailed mapping by Witter and others (2006) of the inner part of the region (compiled at a scale of 1:24,000), is given precedence over the less detailed map

Potomac River ADCP Bathymetric Survey, October 4-7, 2021

Bathymetric LiDAR technology was used to collect riverbed elevation data along the Potomac River. In support of this effort, a bathymetric survey with a boat-mounted acoustic Doppler current profiler (ADCP) was conducted in the study area during October 4-7, 2021. The study area consisted of four verification reaches on the Potomac River including: 1) Williamsport accessed through the Williamsport
