NASA Oversized Loads will Cause a Traffic Jam Late Tuesday Morning in Hesperia down the Cajon Pass on there way to California Science Center

CAJON PASS, CA.

The load is expected to be start traveling at 9am to 12pm stop at the 605 Freeway and times may fluctuate. Map route by the California Science Center.

The two large loads are two Solid Rocket Motors donated by Northrop Grumman Corporation, that have been stored at the Mojave Air and Space Port from the Space Shuttle Endeavor, about 100 miles north of Los Angeles, since September 2020. They will be transported from their current home at the Mojave Air and Space Port to the California Science Center. They are the final elements of space shuttle Endeavour’s stack to arrive at the California Science Center. The components, including NASA’s last remaining built-for-flight external tank, will make up the world’s only exhibit of an authentic shuttle poised for flight. Components of these two Solid Rocket Motors flew on a combined 81 space shuttle flights and 32 static tests, dating back to STS-5 in 1982, the fifth NASA Space Shuttle mission and the fifth flight of the Space Shuttle Columbia.

The last use of a component was for STS-133, the last flight of Discovery. The rocket motors will begin departing the Mojave Air and Space Port at 9am Tuesday, exiting south on Airport Blvd, then east on the Mojave-Barstow Highway, and then continuing to Highway 58 to Hwy 395 down the Cajon Pass then to the California Science Center over the next two days. “We’re excited to see the SRB’s on display in the future.” Said CEO Tim Reid.

On October 11, 2023, from the 605 Freeway the California Science Center will continue Go for Stack with the arrival of two large Solid Rocket Motors (SRMs) that have been stored at the Mojave Air and Space Port. Each Solid Rocket Motor will be mated to an Aft Skirt, already installed in the Shuttle Gallery of the future Samuel Oschin Air and Space Center; then Forward Assemblies will be mated to the top. Once stacked, these elements will complete the Solid Rocket Boosters (SRBs).

You’re invited to watch this historic arrival! On October 11, the SRMs will travel northbound along Figueroa St. beginning at 7:30 am from 43rd Pl. to Martin Luther King, Jr. Blvd. At 8am, the SRMs will pause at Martin Luther King, Jr. Blvd. before crossing a ceremonial finish line at 39th St. at 8:45 am. The public is invited to gather on Figueroa St. from 43rd Pl. to 39th St. to watch the momentous arrival. The Science Center will open at 9am on October 11 for guests to visit Endeavour, engage in hands-on science activities, and enjoy our dining and retail options.
