Go back to 1978 to see the origins of EPCOTs Space pavilion. See how Journeys in Space evolved, and how it was nearly built twice. See the Horizon connection, how Horizons nearly stayed with us and then how the building itself nearly stayed, and then see Mission: Space be announced, built and finally dedicated.
Take a full tour around the exterior plaza, then a full tour of the queue and holding areas inside. Queue for the ride, see all the preshows, then experience the full ride with fullscreen, clear video and a new clear inride audio mix. Walk around the postshow area and gift shop, and see what changes have been made since 2003. Finally, take a peek in the HP VIP lounge too.
