One thing I didn't understand in the interview was at 00:17:20: The idea of Venus being geologically dead based on impact craters. I'm familiar with the "crater counting" technique. Since Venus has so few, wouldn't that bring the assumption that Venus's surface is much more relatively young than Mars? Surly not older? She then says Venus catastrophically resurfaced before the impact craters. I'm confused as to if she's arguing it's older or newer.
Also, Ms. Smrekar says that Mars and Earth have roughly the same number of craters?! Surely the Earth has much less impact craters present on the present day surface than Mars?
Very stimulating discussion! Just a couple things I've been confused about for the last couple days.
