Twin Solid Rocket Motors, which Northrop Grumman pledged to donate to the California Science Center to showcase the Space Shuttle Endeavor in 2017, Arrived at Mojave Air and Space Port in last few weeks, Where they are being temporarily kept in external storage. The inert motor case, which Northrop Grumman described as “structurally representative” of the solid rocket boosters used during NASA’s space shuttle program, was designed for their performance after the company’s promontory, Utah The test was trucked from the facility.
“We are excited to share a piece of more than 30 years of legacy with future generations to help inspire a new era of explorers,” Northrop Grumman’s vice president for propulsion systems and former space commander , Charlie Precourt said in a statement. .

since Debut Endeavor On horizontal display in 2012, the California Science Center plans to display the winged spacecraft vertically, as if it were back on the launch pad, piled up with a fuel tank and solid rocket boosters. Towards that goal, basically the science center Received a pair of boosters Demonstrable at the Kennedy Space Center Visitor Complex in Florida was assembled from a mixture of flyable, tested and simulated parts.
But after NASA reached the finals Flight-worthy external tank, ET-94In 2016, and reviewing performance plans, it was decided that a set of flight-worthy boosters was also required to meet seismic and structural standards. Dennis Jenkins, a veteran shuttle engineer and director of the Science Center’s project to demonstrate Endeavor, requested Northrop Grumman (at the time, Orbital ATK, which was acquired by Northrop Grumman in 2018), which led to his donation.

“For the non-motor parts of the booster, we designed a set of flight-reps Welt and frustration A set of NASA surplus and forward skirts that were used to test for NASA’s Space Launch System (SLS) program that are currently in Utah, “Jenkins said.” Like Northrop Grumman and NASA Booster are providing most of the smaller parts like Separation Motors. , From surplus. ”
when Booster donation was first announcedThe California Science Center was targeting 2019 for the opening of Endeavor’s vertical display at the planned Samuel Oshin Air and Space Center. Although it now has all the components of the spacecraft, the science center is still waiting to break ground on the new building.
“Honestly, we’re still Working on fundraising. We’ve made good progress, but we’re not quite there to begin yet, “Jeff Rudolph, president and CEO of the California Science Center, told collectSPACE.com.” We are optimistic that we will be able to start construction in the next one. year.”
Once the project is funded and the Oshin Air and Space Center is ready for Endeavor, two solid rocket motors that are now in Mojave will be brought to the Science Center with the same pomp and circumstance as the orbiter and External tanks were received earlier.
“These are big, but they are very easy to move. It would still be a very good thing to see through the streets,” Rudolph said.
The 149-foot (45 m) solid rocket booster produced most of the thrust required for the first two-minute flight of the spacecraft. After expanding its propellant, the twin boosters disengaged from the vehicle and landed under the parachute and splashed for their recovery and reuse.
Northrop Grumman is making the most of its remaining shuttle-era solid rocket motor hardware to support NASA’s SLS, which is being built to launch astronauts to the moon. On 2 September, after the second day of two motors arrived at Mojave to perform Endeavor, the company performed a ground test with the SLS Flight Support Booster in Utah, launching the first 43 shuttles.
Endeavor’s well-used boosters include components that were part of 32 static ground trials and 81 space shuttle missions. In the oldest cases, the STS-5, located on top of each assembled solid rocket motor, helped launch the fifth flight of the Orbiter Columbia in 1982. The most recent use was the STS-123, the 21st launch of Endeavor, in 2008. .

In the interim 25 years, cases were used on Challenger, Discovery, Atlantis and Endeavor (STS-6 in 1983, STS-41D in 1984, STS-51J in 1985 and STS-49 in 1988, respectively). Mission to deploy Hubble Space Telescope (STS-31 in 1990), first and last shuttle-mir docking (STS-71 in 1995 and STS-91 in 1998), John Glenn’s return to orbit (STS-95 in 1998) , Colombia’s ailing final mission (STS-107 in 2003) and 22 missions to assemble the International Space Station.
Of Endeavor’s 25 missions, 16 were flown using segments from two solid rocket motors of its performance.
The boosters’ donation creates a partnership of more than a decade between Northrop Grumman and the California Science Center. The company has sponsored the California State Science and Engineering Fair and several of its employees as volunteers each year to advance STEM education by supporting various events. Northrop Grumman has also supported the center’s annual Discovery Ball.
Endeavor will be the only vertical display and the second full stack display of the space shuttle, which will be later Pathfinder Fit-Check Orbiter Mockup At the American Space and Rocket Center in Alabama.
