Programming note: Florida space conference

As I write this I am watching President Obama walk down the steps from Air Force One to attend the Florida space conference and deliver a speech at 14:40 EDT (18:40 UTC) about the future of American space exploration. Lou Friedman, Bill Nye, Scott Hubbard, and Jim Bell were all invited to attend. I'll be Tweeting throughout; go here to see my Twitter feed. You can also watch the proceedings live on NASA TV.
