This is the annual gathering of US astrobiology, and it will be a somber one. The hints of bad news came several weeks ago when NAI there would be no travel support for graduate students to attend the meeting.
It is a large meeting, the "odd year" meetings are NAI specific and not generally open, the even year meetings are open and have a large attendance. The meeting is split into major symposia with a mixture of plenary sessions and parallel sessions with short contributed talks. And of course large poster sessions.
It will be a good meeting, I am expecting a lot of interesting results, some wild speculation and strong synergy.
