The Space Symposium, held at The Broadmoor in Colorado Springs, Colorado, USA, has brought together space leaders from around the world to discuss, address and plan for the future of space since the inaugural event in 1984. Attendees at that original event numbered barely 250 space enthusiasts, while participants in recent years have surpassed 11,000. The Space Symposium has become widely known as the premier U.S. space policy and program forum and as the "must attend" opportunity for information on and interaction among all sectors of space.

Called the National Space Symposium for the first 29 years, the event was renamed in 2014 to Space Symposium to reflect the event's truly global profile.
