LOS ANGELES — The space shuttle Endeavour is absolutely breathtaking in its 20-story new home at the California Science Center's brand-new Air & Space Center, which is set to open on Nov. 13, the museum announced on Wednesday (June 24). After over three decades of ideation, development and construction, the California Science Center has officially announced an opening date for its brand-new Samuel Oschin Air & Space Center, which will feature the space shuttle Endeavour. On Wednesday, I got to peek behind the curtain to see Endeavour's new home inside the center, where it stands in a "ready to launch" position, towering at nearly 200 feet (61 meters) tall — a truly spectacular focal point. The shuttle is even complete with real solid rocket boosters and the last flight-qualified external fuel tank (ET-94). "It's been a lot of years to get here, and it's a dream come true," Lynda Oschin, the chairman of the board and secretary of the Mr. and Mrs. Samuel Oschin Family Foundation, told Space.com about this massive exhibition finally coming together. "They're going to be in tears, they're going to be shaking, and they're going to be proud," Oschin added, referring to how she expects guests to react to Endeavour in its new home. And having just seen it for the first time in all its glory, standing upright with its fuel tank and rocket boosters seemingly ready to launch, I can attest: She is absolutely right. Before you even step foot into the shuttle room, there is a short video that is played that takes you through the history of the shuttle program while bringing to life the fiery excitement of a shuttle launch. In a dramatic cloud of smoke, the shuttle room is revealed and there isn't a single person who isn't in absolute awe. Endeavour is hypnotizing. With the boosters and fuel tank, its already massive stature becomes almost larger than life. The space shuttle Endeavor is larger than life in its new museum home.

Space.com/Chelsea GohdA walkway takes you all the way around the shuttle, which is open on one side so you can clearly peer into its many layers, seeing wires and other details. You can also walk down to a lower floor, where you can stand underneath the shuttle and inspect it from every angle you might want. And surrounding the shuttle itself are a variety of interactive exhibits like a shuttle landing simulator (good luck), the tires from Endeavour's final landing, and more. "I'm a child of the Apollo era, and I remember having a plastic Apollo Saturn V rocket that I carried with me everywhere, and that was after going to Johnson Space Center, visiting the space center there," retired NASA astronaut John "Danny" Olivas told Space.com. "inspiration happens through exposure, and there's nothing, I think, more impressive than standing next to the space shuttle stacked the way that they've done here at the California Science Center."And Endeavour is special in this respect: No other museum has a space shuttle orbiter that's mounted vertically, in the launch position.One aspect of the California Science Center that stands out is its accessibility, as the museum (including the brand-new air and space center) is entirely free to the public — and it's on the metro line, which kids in L.A. can ride for free. Many museums and similar institutions strive for and value accessibility, and this center really takes that to heart, keeping even new installations like the shuttle free to visit. "California Science Center has opened up accessibility for inspiration to the next generation of space explorers," Olivas said. And while NASA moves forward with its Artemis moon program, Olivas, who flew on two shuttle missions (STS-128 and STS 117), is confident that the lessons and history of the space shuttle program will carry on in inspiring that next generation. "One of the things that really touches my heart about the space shuttle program is that it ushered in an age of diversity in space exploration that we had not seen prior," Olivas said. "We got an opportunity to see so many firsts — so many firsts of Americans being able to see themselves in the astronauts that flew in space, and that opened the door to so many people like myself, recognizing that wow, yeah, I can become an astronaut."The new Air & Space Center was first imagined as part of a museum expansion plan all the way back in 1993. Over 30 years later, the futuristic building stands a whopping 20 stories tall to accommodate the towering Endeavour, which immediately grabs the focus of anyone walking into the building. After NASA's space shuttle program ended in 2011, the agency worked to turn itsretired shuttles into museum attractions. Endeavour first arrived at the California Science Center in October of 2012. Thousands watched as the spacecraft rolled through the streets of Los Angeles on the back of a slow-crawling transporter, a 12-mile (19 kilometers) trek from Los Angeles International Airport to the California Science Center that took the craft 68 hours. Four years later, in 2016, ET-94, the shuttle's external fuel tank, arrived. And seven years after that, in 2023, two solid rocket boosters arrived and the shuttle was taken off display, where it had sat for over a decade, as preparations began for its new home in the Air & Space Center. "Now, with the stunning display of Endeavour in launch configuration, the Samuel Oschin Air & Space Center will give us a clear, greater platform than ever before to accomplish our mission to stimulate curiosity and inspire science learning in everyone," said Jeffrey Rudolph, president and CEO of the California Science Center. This "will be the only place in the world to see a complete space shuttle system, with the flown orbiter Endeavour mated to real solid rocket boosters and the only remaining flight-qualified external tank, ET-94."While Endeavour is the clear centerpiece of the building, the Samuel Oschin Air & Space Center will be chock-full of a wide variety of other space artifacts. The building is split into three sections that guests will be able to explore: air, space and shuttle. Relics from throughout spaceflight history, interactive exhibits, and immersive, educational experiences fill the space. Currently, 1.6 million people visit the California Science Center each year, so even if this number were to remain the same, this building has to be ready for a big and diverse crowd from around the world.
