Data

This data collection includes ground-penetrating radar (GPR) data and related observations collected from the NASA Goddard Instrument Field Team (GIFT) Expedition to the Icelandic Highlands in July-August 2019 and August 2021. This dataset includes observations at the Askja Volcano and caldera and Vikrahraun lava flow. GPR data were collected using Geophysical Survey Systems, Inc (GSSI) shielded b

Utilizing the USGS Meteor Crater Sample Collection, we sampled impact melt particles for geochemical and textural characterization using a scanning electron microscope and electron microprobe. Samples were collected from a range of different depths and distances from the crater rim, all within the proximal ejecta blanket. By using the Meteor Crater Sample Collection, in which all samples have know

These data are Lunar Orbiter Laster Altimeter (LOLA) Reduced Data Record (RDR) spot observations, released by the LOLA team to the Planetary Data System (PDS) that have been reformatted into the American Society for Photogrammetry and Remote Sensing (ASPRS) LAZ/Cloud Optimized Point Cloud (COPC) file format.

Grand Falls dune field (GFDF) is located on the Navajo Nation, ~70 km NE of Flagstaff, AZ. This active dune field displays a range of morphologies, including barchans, smaller dunes, and ripples, and is bimodal in composition. The felsic component is likely derived from the Little Colorado River, and the mafic component (basaltic grains) is locally sourced from nearby cinder cones [1]. GFDF is an

This map shows the regional setting of the landing site for the Apollo 15 mission. The area lies approximately 650 km southeast of the center of the Imbrium basin, a large basalt-filled multi-ringed structure in the northwest quadrant of the Moon’s near side. Several arcuate structures surround the Imbrium basin (Hartmann and Kuiper, 1962). The most prominent of these forms the northwest-facing sc

The Taurus-Littrow region is mainly a highland area at the juncture of Mare Serenitatis and Mare Tranquillitatis (Scott and Pohn, 1972). Highland materials cover most of the area, forming a group or rugged massifs close to the center of the map and more subdued terrain to the east. The highland units (pItm, IpIh) are probably mostly breccias formed by the Serenitatis impact and pre-existing brecci

The evolution of the Moon’s surface shows three successive stages (Hartmann, 1970). The earliest, from the beginning of the decipherable record to the Imbrian Period, was dominated by frequent large-scale impacts which produced overlapping and interfering craters and giant multi-ringed basin with ejecta blankets. The second stage, extending through most of the Imbrian to early Eratosthenian Period

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

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

The U. S. Geological Survey's Manned Lunar Exploration Investigations carried out during the second half of Fiscal Year 1965 concept studies for Apollo and for AES exploration, and shirt-sleeve field tests of geologic operations for Apollo exploration. Three Apollo field tests were carried out late in the spring using communications and television systems, a simple LEM mock-up, and other equipment

Incorporated into USGS OpenFile Report #1094, "The Geologic Classification of the Meteorites", these materials were written by Donald Elston and contain figures, photos, and charts to help astronauts (who were not trained geologists) be able to identify and articulately describe the geologic observations they made on the lunar surface.
