Elysium’s eruptive history
Elysium is Mars’ second-largest volcanic province after Tharsis. A new study by Thomas Platz and Gregory Michael (Freie Universität Berlin) published in Earth and Planetary Science Letters (October 30, 2011) counts craters on its volcanos and the main lava flows … Continue reading
How often does Mars get whacked?
Or — to pose this question more usefully — what’s the rate of crater-making impacts on Mars as compared to, say, the Moon? Why the Moon? Because it’s the one extraterrestrial body for which scientists have both a long visible … Continue reading
