Geomorphological evidence of near-surface ice at candidate landing sites in northern Amazonis Planitia, Mars
This work presents geomorphological analyses of an area at the boundary between Arcadia Planitia and northern Amazonis Planitia, situated in the northern mid-latitudes of Mars. Recent studies have indicated the presence of substantial volumes of near-surface excess ice in Arcadia Planitia, making this region a promising candidate for future human and robotic exploration. This study...
U.S. Geological Survey 2024 Rocky Mountain Region Science Exchange—Showcasing cutting-edge science to adapt to extreme weather events and stakeholder needs
IntroductionThe Rocky Mountains and the Colorado River Basin in the Western United States are complex, interconnected systems that sustain a large variety of species, including tens of millions of humans. These regions face risks from drought, wildfires, invasive plant and animal species, and habitat reduction. Working with many stakeholders, scientists can help to characterize these...
From hydrated silica to quartz: Potential hydrothermal precipitates found in Jezero crater, Mars
On Earth, silica-rich phases from opal to quartz are important indicators and tracers of geological processes. Hydrated silica, such as opal, is a particularly good matrix for the preservation of molecular and macroscopic biosignatures. Cherts, a type of silica-dominated rocks, provide a unique archive of ancient terrestrial life while quartz is the emblematic mineral of the Earth's...

Python Hyperspectral Analysis Tool (PyHAT)
The Python Hyperspectral Analysis Tool (PyHAT) provides access to data processing, analysis, and machine learning capabilities for spectroscopic applications. It includes a GUI so you can get straight to analyzing data without writing any code. Or, if you are comfortable writing code, PyHAT can be imported just like any other Python package.
Analysis Ready Data
Astrogeology is a world leader in developing and releasing analysis-ready planetary science data sets that are approachable and usable by anyone. We take care of all of the processing and provide data that "just work" so that users can focus on what interests them instead of getting stuck on data processing.
Planetary Volcanology
The USGS Astrogeology Science Center conducts research on planetary volcanology. Volcanism is a key part of the chemical and thermal evolution of planetary bodies, and volcanic eruptions are one of the fundamental processes that create and alter the surface of planetary bodies. We often study volcanoes on Earth in order to better understand eruptions across the Solar System, but we also bring...
