Martian Meteorite Means More atMosphere

I am overwhelmed right with too much work to do (especially prepping for Gnomedex) so instead of some thoughtful pun-laden post about the whopping big meteorite the rover Opportunity found on Mars, I'll let Starts With A Bang recount the tale. You can read how this big ol' piece of interplanetary debris seems to strongly hint that a long time ago, Mars had a much thicker atmosphere.


Oh, you can see this on the NASA site as well.
