SpaceUp will take place on February 27-28 at the San Diego Air & Space Museum.
SpaceUp is the first space unconference open to all, where participants decide the topics, schedule, and structure of the event. Unconferences have been held about technology, science, transit, and even cupcakes, but this is the first one focused on space exploration.
SpaceUp is your unconference! Everyone who attends SpaceUp is encouraged to give a talk, moderate a panel, or start a discussion. Sessions are proposed and scheduled on the day they’re given, which means the usual “hallway conversations” turn into full-fledged topics.
