NewSpace 2008: Creating the Future or Living in the Past (I can hear Jethro Tull in the background) is at the Doubletree Hotel in Crystal City July 17-19. Details are at http://www.space-frontier.org/Events/NewSpace2008.
On the evening of the 16th, the Foundation is co-sponsoring a space policy roundtable with the NewSpace Alliance and the Space Policy Institute of George Washington University.
The roundtable, on the topic of Teachers in Space, will take place at George Washington University beginning at 6:30 PM.
A free catered reception with food and drink will follow the roundtable.
There's also additional information, including a link to a Google map for the location, on the Teachers in Space blog:
