“We astronauts are right here right now to salute all those that made our journey into area attainable. They’ve permitted us to see the Earth as a valuable blue jewel within the blackness of area. Now all of us might get pleasure from this sense of marvel due to Walt Disney.”
With these phrases 50 years in the past right now (Jan. 15), Apollo 15 moonwalker Jim Irwin opened Space Mountain at Walt Disney World’s Magic Kingdom in Florida. Later to be reproduced at different Disney theme parks, this was the unique — the primary curler coaster meant to offer the general public the identical feeling that solely astronauts had skilled up till then.
“Blast off on a rip-roaring rocket into the furthest reaches of outer area on this roller-coaster experience at midnight,” reads the present description of House Mountain on the Walt Disney World Resort web site.
In 1975, nonetheless, the very thought for such a experience preceded the existence of the know-how wanted to construct it. First proposed by Disney and sketched out by Imagineer John Hench in 1964, building on House Mountain didn’t start till Dec. 15, 1972, simply because the final Apollo astronauts to stroll on the moon have been on their method again to Earth. It was additionally six years after the dying of Walt Disney.

“Walt had a dream,” stated Irwin simply earlier than hundreds of doves have been launched, daytime fireworks have been launched and 50,000 pink, white and blue balloons climbed into the sky. “At present we see the outcomes of that dream.”
Wanting on the experience right now, whereas actually nonetheless a thrill, it has little resemblance to actual spaceflight. However within the 50 years that House Mountain has been operating, there have been and nonetheless are a number of nods to NASA and actual area exploration. Listed below are 5 such connections, from each behind the scenes and on the experience.
1. NASTRAN
House Mountain was one of many first computer-controlled curler coasters. If the experience’s “area shuttles” (or “rocket sleds”) approached one another too intently, the computer systems slowed or stopped the automobiles.
However that is not the one method WED Enterprises (right now, Walt Disney Imagineering Analysis and Growth) used computer systems to make sure riders’ security.
When engaged on the design for the assist construction for House Mountain’s twin tracks, the Imagineers wanted it to be sturdy however not wastefully overbuilt. That’s once they realized of the NASA Structural Evaluation Program, or NASTRAN. An offshoot of the software program used to design air and spacecraft, NASTRAN enabled the Imagineers to digitally mannequin and take a look at the experience monitor earlier than constructing it.
“On this approach, engineers create a mathematical mannequin of the aeronautical or area automobile and ‘fly’ it on the bottom by the use of pc simulation. The approach allows them to review efficiency and structural habits of plenty of totally different designs earlier than selecting the ultimate configuration and continuing with building,” wrote James Haggerty in “Spinoff 1977,” an annual report put out by NASA about how its analysis and applied sciences are being put to make use of by business and others exterior of the area program.
2. From computer systems to outer area
In 1975, the RCA Company was engaged on the event of closed-circuit tv and different numerous subsystems for NASA’s then-upcoming area shuttle program. It was additionally the presenting sponsor for House Mountain.
“Naturally, the essential function of House Mountain from the corporate’s standpoint is to offer the general public a vivid image of what RCA is all about and what it has completed in such various areas of as area exploration, digital communications and residential leisure,” stated Mort Gaffin, RCA’s director for company identification and graphics and undertaking supervisor for House Mountain, within the February/March 1975 problem of the corporate’s publication, “Talk.”
Actually, it could be due to RCA that House Mountain launched the general public on rockets and never motherboards. Initially, Imagineers Hench and Marty Sklar approached the corporate about sponsoring a experience that might take visitors on a journey via a pc. It was solely after RCA rejected that concept did Hench decide up on Disney’s need for a spaceflight expertise, resulting in RCA approaching board for $10 million.
On House Mountain, riders noticed astronauts engaged on an RCA-built Environment Explorer Satellite tv for pc and an orbiting laboratory being assembled remotely utilizing TV techniques furnished by RCA.
A tall pylon put in on the entrance to House Mountain displayed the RCA emblem at its high and included the one direct reference to NASA. A full-size experience automobile was suspended from the monument, full with 4 astronaut figures. The spacesuits every astronaut rider is carrying had the NASA insignia on its chest.
(RCA’s sponsorship ran till 1993. The pylon was modified to indicate a three-seat automobile in 1989, per the change to the seating on the experience itself. 5 years later, the pylon was eliminated and changed with considered one of a special design.)
3. ‘One Large Step’
On the base of the RCA pylon was a metallic plaque “introduced by missile, area and vary pioneers.”
“Devoted to the women and men whose expertise, sacrifice, braveness and teamwork opened the door to the exploration of man’s thrilling new frontier outer area. As a result of they dared to succeed in for the celebrities and the planets, man’s information of his universe, Earth and himself has been drastically enriched,” learn the plaque, which was titled “One Large Step.”
It was a type of astronauts, Irwin, who took the primary “small step” (or “big leap,” relying in your perspective) onto House Mountain on opening day, because the experience’s first passenger.
“It is virtually as tough because the experience on the Saturn V rocket,” the Apollo 15 lunar module pilot stated in an interview with RCA, referring to his experience to the moon.

Becoming a member of Irwin on the ceremony have been Mercury astronauts Scott Carpenter and Gordon Cooper. Carpenter had been the second American to orbit Earth in 1962; Cooper adopted him because the last “original” astronaut to fly a yr later after which commanded NASA’s Gemini 5 mission in 1965.
In 1973, Cooper joined WED Enterprises to assist develop Epcot and put the ultimate touches on House Mountain, the latter of which he stated supplied a “practical feeling” of what it felt like to fly into space. He additionally recorded a video that visitors noticed when queuing up for the experience, explaining what they have been about to undergo and giving them the prospect to exit ought to they modify their thoughts.
4. Rocket to the Moon
Previous to House Mountain, Disney’s first space-themed attraction was “Rocket to the Moon.” Situated in California as a part of Disneyland’s Tomorrowland (and later reproduced as “Flight to the Moon” at Walt Disney World in Florida in 1971), the present was developed with NASA’s help. The attraction was re-themed to “Mission to Mars” at each parks inside months of House Mountain opening on the Magic Kingdom in 1975.
There may be now a reference to the since-closed Mission to Mars on a panel in House Mountain’s queue, however it’s one other signal and a special “rocket to the moon” that serves as a nod to actual area historical past.
Earlier within the line for the experience, a backlit billboard lists “Lively Lunar Stations” accessible from “Starport Seventy-5” (the fictional setting for House Mountain). Along with science fiction and Disney-inspired names, the third entry reads, “TRNQ-ARMSTRONG Interplanetary.”
If not apparent, this can be a tribute to Apollo 11 commander Neil Armstrong, who was the primary individual to walk on the moon at Tranquility Base in 1969.
(In 2005, the true Armstrong helped re-open House Mountain at Disneyland after it underwent two years of renovations.)
5. House (Race) Mountain
The festivities marking the opening of House Mountain was not the one time that actual area vacationers met on the fictional starport. Lower than a month later, the attraction turned the rendezvous level for 2 crews set to shake palms in orbit.
In 1975, the area race between america and Russia had all however come to a detailed (the moon’s floor being the end line), however the two nations have been nonetheless Chilly Struggle rivals. So it was a giant deal when astronauts and cosmonauts got here collectively through the first joint American and Russian area mission in July 1975.
5 months earlier than they launched into area, the 5 members of the Apollo-Soyuz Check Mission (ASTP) visited Walt Disney World, the place they rode the newly debuted House Mountain. The Feb. 9, 1975 go to by NASA astronauts Thomas Stafford, Vance Model and Deke Slayton and Russian cosmonauts Alexei Leonov and Valery Kubasov was an opportunity for each crews to calm down and generate some publicity earlier than the Russians reported for his or her final coaching session in Houston.
Nonetheless laughing quickly after getting off House Mountain, Leonov described the experience as “an actual good built-in simulator” for his or her upcoming mission.
