Did You See That? Two Pieces of Space History Traveling down the Cajon Pass

CAJON PASS, CA. (Pain In The Pass) >> Commuter may have notice or parked to see a piece of space history travel down the Cajon Pass Monday morning. (Photo above is credit by Steve Anderson)

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 in Mojave, CA., about 100 miles north of Los Angeles, since September 2020. The motors are from the Space Shuttle Endeavor. They transported from Mojave Air and Space Port to the California Science Center in Los Angeles. 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.

Pain In The Pass Facebook Group member Steve Anderson was able to escort them from Adelanto to the 15 freeway and was able to take pictures and videos of them driving by.
