SpaceUp Stuttgart, October 2012 - Germany's first space unconference.
SpaceUp NZ is an unconference -- where participants influence the topics, schedule, and structure of the event.
The first SpaceUp was held in February 2010, organized by the San Diego Space Society. More than 20 SpaceUps have been held all around the world since then, and many more are scheduled or planned. See the global SpaceUp website for more information.
Everyone who attends SpaceUp is encouraged to give a talk, moderate a panel, or start a discussion. New sessions are proposed during the weekend, and the schedule is adjusted to accommodate trending topics - which means the usual “hallway conversations” turn into full-fledged discussions.
But don't be scared by the requirement to speak -- there are plenty of ways to participate that will suit your personal style. You don't need to be a public speaking guru to fit in at SpaceUp.
The unconference format has been used successfully for a wide variety of topics – but is most well-known in the software/programming sector. A New Zealand example is Gather, which has been operating since 2007 and had around 275 attendees at the event in 2013.
