Astrogeology has eyes on Mars through Mastcam-Z on Perseverance Rover

Astrogeology has eyes on Mars through Mastcam-Z on Perseverance Rover. The Mars 2020 Perseverance Rover arrived on Mars' surface in February 2021 carrying several instruments to conduct science experiments and look for evidence of past life. One such instrument is Mastcam-Z, a stereo high-resolution color zoom camera that gives us the ability to create 3D images.

Advancing cave detection using terrain analysis and thermal imagery

Since the initial experiments nearly 50 years ago, techniques for detecting caves using airborne and spacecraft acquired thermal imagery have improved markedly. These advances are largely due to a combination of higher instrument sensitivity, modern computing systems, and processor-intensive analytical techniques. Through applying these...

Geologic map of Olympus Mons caldera, Mars

The Mars volcano, Olympus Mons, is probably the best known extraterrestrial volcano. The summit forms a nested caldera with six overlapping collapse pits that collectively measure ~65 x ~80 kilometers (km). Numerous wrinkle ridges and graben occur on the caldera floor, and topographic data indicate >1.2 km of elevation change since the...

A geologic field guide to S P Mountain and its lava flow, San Francisco Volcanic Field, Arizona

IntroductionWe created this guide to introduce the user to the San Francisco Volcanic Field as a terrestrial analog site for planetary volcanic processes. For decades, the San Francisco Volcanic Field has been used to teach scientists to recognize the products of common types of volcanic eruptions and associated volcanic features. The volcanic...
