The California Science Center (CSC) has unveiled an extraordinary museum exhibit featuring the space shuttle Endeavour. Endeavour stands fully vertical, assembled with real solid rocket boosters and its last flight-qualified external fuel tank. This configuration replicates its appearance at Kennedy Space Center ready for launch. Endeavour, built as a replacement for the Challenger, completed 25 missions, traveling over 122 million miles and orbiting Earth thousands of times. It played a crucial role in servicing the Hubble Space Telescope and delivering components to the International Space Station. Its final flight delivered the Alpha Magnetic Spectrometer to the ISS. After its last landing in 2011, Endeavour was transported to the CSC. The "Go for Stack" process, a six-month mating procedure, brought the 185-foot tall shuttle to its current display. This assembly was incredibly challenging, involving intricate seismic engineering and precise alignment of components. The team overcame numerous logistical and technical hurdles never before encountered in a museum setting. Despite its fragility, Endeavour is displayed under strict conservation standards for optimal preservation. The exhibit opens to the public on November 13, 2026, with free admission requiring timed-entry reservations.
