UA reports 100 crater-forming meteorite hits per year on Mars
Catching up on my journals, I see that UA planetary scientist Ingrid Daubar and her colleagues used cameras on the Mars Reconnaissance Orbiter to determine that Mars gets hit with 100 new crater-f0rming meteorites hits per year. [right, "locations of 189 newly discovered recent impact sites on Mars. The majority of sites are in areas of high dust cover." Credit, LPSC]
The results were presented at the Lunar & Planetary Science Conference outside Houston in March.
