My abstract on “Warming Early Mars with NO2” has been accepted for a talk at this summer’s Astrobiology Graduate Conference! I’ll discuss a possible mechanism by which early Mars (3 billion years ago) could have sustained above-freezing temperatures as well as liquid water with a carbon dioxide/water vapor/nitrogen dioxide greenhouse effect. We are currently putting the finishing touches on our manuscript before submitting it to Earth & Planetary Science Letters in a week or so.
The organizers of AbGradCon09 have done a great job of putting together an excellent conference, including a field trip to Mt. St. Helens. Additionally, the conference will be broadcast live on Second Life, so if you can’t travel to Seattle you can still participate!
