Do you know how to protect yourself in an Earthquake? The 2021 International ShakeOut Day is on October 21, and you can learn what to do before an earthquake happens by participating in the ShakeOut Earthquake Drills.
Tour of Water in the Solar System
Happy Earth Week! This year, the theme for Earth Week is Water. Let’s take a tour of the solar system and see where else water exists, and why it’s so unique that water exists in the forms that it does here on Earth!
A Virtual Field-trip Guide to S P Mountain Just Released by Astrogeology Science Center!

Active neutron interrogation experiments and simulation verification using the SIngle-scintillator Neutron and Gamma-Ray spectrometer (SINGR) for geosciences
We present a new SIngle-scintillator Neutron and Gamma Ray spectrometer (SINGR) instrument for use with both passive and active measurement techniques. Here we discuss the application of SINGR for planetary exploration missions, however, hydrology, nuclear non-proliferation, and resource prospecting are all potential areas where the instrument...

Past, present, and future of Mars Polar Science: Outcomes and outlook from the 7th International Conference on Mars Polar Science and Exploration
Mars Polar Science is a subfield of Mars science that encompasses all studies of the cryosphere of Mars and its interaction with the Martian environment. Every 4 yr, the community of scientists dedicated to this subfield meets to discuss new findings and debate open issues in the International Conference on Mars Polar Science and Exploration (...

Geologic map of the Athabasca Valles region, Mars
This 1:1,000,000-scale geologic map of the Athabasca Valles region of Mars places the best-preserved lavas on Mars into their geologic context. The map shows vigorous geologic activity in the most recent epoch of the geologic history of Mars, which is extremely unusual for the planet. In these atypically youthful terrains, the interpretations of...
