The Space Frontier Foundation's annual NewSpace Conference is the ultimate space-industry event--so focused on the private companies that comprise said industry that NASA is rarely mentioned, just the way the NewSpace Movement likes it. It also happens to be the first conference where SpaceWiki had a booth, so we may be a bit biased.
