AmericaJR’s Jason Rzucidlo recently visited the California Science Center near the USC campus in Los Angeles. The museum is known for hosting Space Shuttle Endeavour, but also houses an External Tank.  It carried propellants—liquid oxygen and liquid hydrogen—that flowed into the Space Shuttle Main Engines (SSMEs), where they combined and ignited to produce almost one and a half million pounds of thrust to help push the space shuttle to orbit. The external tank destined for display at the California Science Center is ET-94, the last flight-qualified external tank in existence. This lightweight tank (LWT)—donated to the Science Center by NASA—was ordered to support science missions for space shuttle Columbia.

Visit the California Science Center following the COVID-19 pandemic at 700 Exposition Park Drive, Los Angeles, CA 90037. Hours are 10 a.m. to 5 p.m. daily. General admission is free. Special exhibits required a paid ticket. More info at:
