For fourteen years, Space Shuttle Endeavour lay flat in a temporary pavilion in Los Angeles, nose pointing at a wall. On Friday, November 13, 2026, that changed forever: the shuttle opened to the public standing upright, fully stacked with its orange external tank and twin solid rocket boosters, exactly as it looked on the launch pad. It is now the only place on Earth where you can see a complete, authentic space shuttle system in launch position — and the sight of it stops people in their trac
ks.
The new home is the Samuel Oschin Air and Space Center at the California Science Center in Exposition Park, Los Angeles. The building itself is a 200,000-square-foot expansion that nearly doubles the museum's exhibit space, and its centerpiece, the Samuel Oschin Shuttle Gallery, towers nearly 200 feet high. Inside it, Endeavour rises 185 feet — about twenty stories — mated to ET-94, the last flight-qualified external tank in the world, and a pair of real solid rocket boosters.
Why vertical matters — and why it took so long
Every other retired shuttle on display — Atlantis in Florida, Discovery in Virginia, Enterprise in New York — lies horizontal, the way it landed. That is practical, but it hides what a shuttle really was: not an airplane, but the top of a rocket stack. Standing Endeavour upright restores the truth of the machine. You see the orbiter the way astronauts saw it from the crew access arm, and you grasp the scale of the system that carried people to orbit for thirty years.
Getting it upright was a feat of engineering in its own right. The mating process, called "Go for Stack," took about six months and finished in 2024. In January 2024, a 450-foot crane lowered the orbiter onto the waiting stack in a maneuver that had never been attempted outside a NASA facility. The whole center is the third and final phase of the Science Center's 30-year master plan — three decades of fundraising, design and construction to give the shuttle a permanent home.
What you actually see inside
The Shuttle Gallery is designed to be walked around at several levels, so the stack reveals itself differently from the floor and from above. The showpiece is the Launch Tower, a 140-foot elevator ride that carries you up alongside the shuttle to a glass-floor observation platform hovering over Endeavour's nose — the closest a civilian will ever get to standing on a launch tower. For the descent, there is a tubular slide with a 45-foot drop that represents the shuttle's glide back from orbit.
The building holds two more galleries beyond the shuttle: the Korean Air Aviation Gallery and the Kent Kresa Space Gallery, with about 100 interactive exhibits between them, plus rare artifacts from the history of flight and space exploration. The opening ceremony drew around 30 astronauts, including all six crew members of Endeavour's final mission, STS-134, commanded by now-U.S. Senator Mark Kelly.
Endeavour's own story
Endeavour was the last orbiter ever built, ordered as the replacement for Challenger after the 1986 disaster. It flew its maiden mission in May 1992 and went on to fly 25 missions, including the first repair of the Hubble Space Telescope and the delivery of the first American component of the International Space Station. When the shuttle fleet retired in 2011, Los Angeles won the competition to display it, and the orbiter made its famous 12-mile crawl through city streets to Exposition Park in 2012.
That history is part of why the vertical display lands so hard. For a generation of visitors, the shuttle was the machine on the television screen. Seeing it stacked and ready, twenty stories tall, turns an abstraction into something physical — the way Voyager 1, now nearly a light-day from Earth, turns the scale of space into something you can feel. Big machines, honestly displayed, teach better than any plaque.
How to visit
General admission to the California Science Center is free, and that includes the new Air and Space Center — but entry uses free timed reservations because of expected demand, with a small service fee to book a slot in advance. The museum is open daily from 10 a.m. to 5 p.m. at 700 Exposition Park Drive, Los Angeles, and the opening weekend, November 13–15, features astronaut and aviation talks every half hour. If you go, book ahead: the first weekends are expected to sell out their reservation slots.
There is a reason museums fight so hard over objects like this. A shuttle lying flat is a retired airplane. A shuttle standing vertical, stacked and ready, is a promise — the same promise that drives SpaceX's Starship test program and the giant engineering projects still being built today: that humans build machines to go further than seems reasonable, and then they do. In Los Angeles, for the first time, you can stand underneath that promise and look straight up at it.
