named Citizen Space. This Barcamp-style "unconference" is an event where they participants determine the schedule and all are encouraged to be on a panel or lead a talk. Cost for the weekend is $50 (that includes 3 meals, snacks and a T-shirt). As of this writing, tickets are still available. Register at http://spaceupsf.org/registration/
If you can't make it in person, don't panic. Spacevidcast will be streaming portions of the event here: http://www.spacevidcast.com/. I also wrote a brief article about SpaceUp SF at Examiner.com http://www.examiner.com/nasa-in-oakland/spaceup-rockets-into-san-francisco-march-31-april-1
