Saponite Bearing Material Excavated During the Formation of a Recent 25‐m‐Diameter Impact Crater in Southeastern Arabia Terra on Mars

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Mars Reconnaissance Orbiter's Compact Reconnaissance Imaging Spectrometer for Mars (CRISM), Context Imager (CTX), and High Resolution Imaging Science Experiment observations were analyzed for a 25‐m‐wide impact crater and associated ejecta deposits located in the dust‐covered Arabia Terra region.

Comet craters versus asteroid craters

Advances in Space Research, 1991
Abstract The assumptions used to determine whether active comets or earth-crossing asteroids currently dominate the terrestrial cratering rate are reviewed and intercompared. The principal sources of uncertainty are the number and mass distributions of earth-crossing bodies, the adopted crater-diameter scaling law, and the question whether the ...
