To be honest, I find AGU's size to be intimidating and exhausting. I much prefer smaller meetings like the Lunar and Planetary Science Conference and the Division for Planetary Sciences annual meeting, where you stand a better chance of encountering people in the hallways for illuminating informal conversations. These just don't seem to happen at AGU. On the plus side, AGU is such a large meeting that the press room is always packed, so it provides a rare opportunity for me to meet many of my journalistic peers in person.
The planetary science sessions to be livestreamed are as follows. They will also be available for on-demand viewing within 24 hours of filming. Ones listed as "on-demand only" will not be livestreamed. All times are Pacific (UTC-8).
As for me, I will be attending in person on Monday, Tuesday, and Friday. Most of Monday and some of Tuesday will be taken up with Curiosity results. On Tuesday I also plan to attend the press briefings on Juno's Earth flyby, Mars, and comet ISON. On Friday I will be chairing a session on "The Era of Citizen Science: Intersection of Outreach, Scientific Research and Big Data." I'll post more about that next week. And Friday will wrap up with a session on Europa.
I'm sure I'll be Tweeting up a storm, and will try to compose a blog post or a few. Casey Dreier will be attending AGU all week, as will Mark Hilverda, so follow them, too. You can try following the hashtag #AGU13 but it will be a firehose of information. In the past, it has helped stem the flow for me to search Twitter using "#AGU13 -RT" to suppress retweets.
