GIS project files and imagery data required to complete the Introduction to Planetary Image Analysis and Geologic Mapping in ArcGIS Pro tutorial. These data cover the area in and around Jezero crater, Mars.
Appendices include the original survey, response data, and collated results related to the Open File Report. Geoscience maps, regardless of target body, are spatial and temporal representations of materials and processes recorded on planetary surfaces (Varnes, 1973; Spencer, 2000). The information and context provided by these maps promote basic and applied research within and across various geoscience disciplines. They also provide an important basis for programmatic and policy decisions (for example, H.R. 2763 – 102nd Congress, National Geologic Mapping Act of 1992). Since 1961, planetary (that is, all solid surface bodies in the Solar System beyond Earth) geoscience maps have been used in nearly every facet of...
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.
Although ice in the Martian mid-latitudes is typically covered by a layer of dust or regolith, it is exposed in some locations by fresh impact craters or in erosional scarps. In both cases, the exposed ice is massive or excess ice with a low lithic content. We find that erosional scarps occur between 50–61 north and south latitude, and that they are concentrated in and near Milankovič crater in the northern hemisphere and southeast of the Hellas basin in the southern hemisphere. These may represent locations of particularly thick or clean bodies of ice. Pits created by retreat of the scarps represent sublimation-thermokarst landforms that evolve in a manner distinct from other ice-loss landforms on Mars. New impact...
To support the discovery and use of Earth data relevant to the research of geophysical processes on solid bodies throughout the Solar System.
This dataset consists of data from monitoring of gullies on Mars using the High Resolution Imaging Science Experiment (HiRISE). Table 1 provides a list of monitored locations, which are HiRISE image series covering Martian gullies with a time baseline of at least 4000 Mars Reconnaissance Orbiter (MRO) orbits. Images from these locations were blink-compared at 1 m/pix to search for changes on the gully channels and aprons. Observed changes are documented in detail in Table 2. This compilation uses HiRISE data acquired through MRO orbit 61299.
