A billion or more years of possible periglacial/glacial cycling in Protonilus Mensae, Mars
Richard J. Soare, Jean-Pierre Williams, Adam J. Hepburn +1
The long-term cyclicity and temporal succession of glacial-periglacial (or deglacial) periods or epochs are keynotes of Quaternary geology on Earth. Relatively recent work has begu…
Global regolith thermophysical properties of the Moon from the Diviner Lunar Radiometer Experiment
Paul O. Hayne, Joshua L. Bandfield, Matthew A. Siegler +8
We used infrared data from the Lunar Reconnaissance Orbiter (LRO) Diviner Lunar Radiometer Experiment to globally map thermophysical properties of the Moon's regolith fines layer.…
The Production of Small Primary Craters on Mars and the Moon
Jean-Pierre Williams, Asmin V. Pathare, Oded Aharonson
We model the primary crater production of small (D < 100 m) primary craters on Mars and the Moon using the observed annual flux of terrestrial fireballs. From the size-frequency di…
Low paleopressure of the Martian atmosphere estimated from the size distribution of ancient craters
Edwin S. Kite, Jean-Pierre Williams, Antoine Lucas +1
The decay of the martian atmosphere - which is dominated by carbon dioxide - is a component of the long-term environmental change on Mars from a climate that once allowed rivers to…
