The Space Theater opened to the public in August of 1986 as part of the first phase of construction of this museum. Originally it was equipped with 15/70 IMAX film projection system from Canada and space simulating system from GOTO Optical Institute in Japan. In 1990, it broke attendance records with more than 660,000 audience members. In July of 2015, the Space Theater was updated with Digistar 5 digital theater and planetarium systems from E&S in the US, allowing for a more flexible and lively theater and planetarium experience.
