Free Admission Sunday at The California Science Center - see INFO below. Shuttle Gallery will reveal how the worlds first reusable spacecraft has helped us learn to live and work in low Earth orbit and prepare for bolder and more distant missions. The California Science Center will be the only place in the world to see a complete Space Shuttle System with a flown orbiter, Endeavour, mated to real solid rocket boosters and ET-94, the last remaining flight-qualified external tank. In addition to preserving an important part of space exploration history, guests will have an unparalleled educational experience as they view this national treasure up close from multiple angles and elevations. The Samuel Oschin Air and Space Center is the primary component of Phase III of the California Science Center's 25-year Master Plan. When finished, the California Science Center will be the largest science center in the western United States. The EndeavourLA Campaign supports this exciting vision for the future.
