Historic moon rocket engine mockup takes short trip to new L.A. display

October 3, 2013 — A mockup of a mighty moon engine took a short trip under moonlight Wednesday (Oct. 2), as it moved from its display of 35 years to a nearby outdoor pedestal in Los Angeles.

The 19-foot-tall (5.8-meters) Apollo F-1 engineering model was partially disassembled and then trucked the 3.3 miles (5.3 km) from outside the Canoga Park factory where the massive engines were assembled in the 1960s to Aerojet Rocketdyne's facility in Chatsworth, California. The move preceded the company closing the plant by the end of the year.

"We're moving the monument, the F-1, from that location because it's an important representation of our successful past," Brian Lariviere, the Aerojet Rocketdyne manager for the development of an upgraded version of the F-1 engine, said in an interview with collectSPACE. "We're moving it to our headquarters here, the Los Angeles headquarters of Aerojet Rocketdyne, to represent where we are going to go in the future."

F-1 engines provided the thrust needed to launch NASA's 363-foot-tall (110-m) Saturn V rocket, which carried Apollo astronauts to the moon and lofted the United States' first space station, Skylab. Each first-stage cluster of five F-1 engines put out the energy equivalent to 85 Hoover dams.

Rocketdyne, which at the time was part of North American Aviation (later Rockwell, Boeing, Pratt & Whitney and then since June of this year, Aerojet) produced a total of 98 F-1 engines, from which 65 were used to launch 13 Saturn V rockets between 1967 and 1973.

The full-scale model on the move Wednesday, which was referred to as Engineering Mockup 1 (EM1), was originally located on Rocketdyne's Canoga Park plant floor, where it was a reference for engineers building the real engines.

"It was used in the 1960s, back when configuration control was a little less formal," Lariviere explained. "They'd make a mockup to take dimensions and final measurements."

In 1976, after the Apollo program ended and production of the F-1 was halted, Rockwell donated the EM1 mockup to the Smithsonian, which in turn loaned it back for display outside the Rocketdyne plant. It sat there undisturbed until earlier this week, when it was hoisted onto a truck for the move to Chatsworth.

Riding on a flatbed, the "oversize load" F-1 engine rode up Victory to De Soto Avenue, then turned up De Soto, where it arrived at the Aerojet Rocketdyne facility at the corner of Nordhoff Boulevard. Today, it was offloaded from the truck and mounted onto its new pedestal.

The F-1 "monument" will now serve as inspiration for the Aerojet Rocketdyne engineers working to design and build an upgraded, affordable version of the engine, which could be used for NASA's next-generation heavy-lift rocket, the Space Launch System (SLS).

In its advanced 130-metric-ton configuration, the SLS will be the most powerful rocket ever built, able to support any destination, payload and mission, according to NASA. The space agency is planning to use the SLS to launch crews to Mars by the 2030s.

"We are looking at the F-1 engine as an upgrade today to provide a booster engine for the SLS advanced booster configuration and looking toward furthering NASA's human space exploration," Lariviere said.
