Space Mountain closed on 4/9/2003 to undergo a major refurbishment. The entire roller coaster contained within the Space Mountain structure was replaced. Since all the ride hardware changed, a new entry was created for the new Space Mountain which opened in 2005 for the park's 50th anniversary.
Strobe lights and star machines to create space effect.
A soundtrack was added in 1996 -- Aquarium of the Animals remixed by Dick Dale.
