The California Science Center announced Monday that construction has been completed on its new Samuel Oschin Air & Space Center, bringing the highly anticipated expansion one step closer to its public debut.

The culmination of a master project plan adopted in 1993, the sleek 20-story, 200,000-square-foot new building rising over Exposition Park will nearly double the museum’s exhibit space and anchor a $450-million campaign to permanently house the retired space shuttle Endeavour.

“I keep saying this, and it sounds cliché,” said Jeffrey Rudolph, the Science Center’s president and chief executive. “But it’s better than we ever dreamed.”

The Samuel Oschin Air & Space Center will be split into three galleries — air, space and shuttle — containing aerospace artifacts and hands-on exhibits demonstrating scientific principles.

At the heart of the new addition is Endeavour itself, displayed in a vertical “ready-to-launch” configuration that’s never been replicated with real hardware outside of a NASA or Air Force facility. The display includes rocket boosters from manufacturer Northrop Grumman and a massive external fuel tank from NASA.

A veteran of 25 missions from 1992 to 2011, Endeavour arrived in L.A. in 2012 during a widely watched journey atop a modified Boeing 747, followed by a slow procession through city streets. For over a decade, the retired orbiter was exhibited horizontally in a temporary, tent-like structure known as the Samuel Oschin Space Shuttle Endeavour Display Pavilion.

In early 2024, Angelenos watched as the shuttle was carefully lifted and placed into its final upright position in an intensive overnight operation.

With several observation areas spanning the nearly 200-foot tall shuttle stack, Rudolph said the new installation will offer visitors “views that almost no one’s ever seen.”

A cutting-edge building design by architectural firm ZGF Architects contributes to that awe-inspiring experience with a 2,000-ton curved structural framework of diagonally intersecting steel beams called a diagrid, which eliminates interior columns and allows visitors unobstructed views of the shuttle stack.

The idea is that “you don’t have a sense there’s a building at all,” said Ted Hyman, partner at ZGF Architects. Instead, you’re meant to feel like you’re standing on a launch pad outside. The dimness of the shuttle gallery also assists in the immersive fantasy, both as an artistic choice and a practical one due to the shuttle’s sensitivity to light.

Yet while the structure is designed to be undetectable from the inside, it’s a full-blown metallic colossus on the outside — visible from the surrounding L.A. freeways. Its colors are most magnificent at sunset.

When asked whether he’d had any doubts about the feasibility of the intricately choreographed construction project, Hyman replied, “I think up until about last week.”

Nonetheless, he said, “you forget about the challenges when you see the building done.”

Lynda Oschin, wife of the new air and space center’s titular philanthropist Samuel, called the project a “dream come true.”

“This space shuttle is everything rolled into one that my husband loved: astronomy, innovation, exploration, science, math and especially children,” Oschin said. “What this is going to do for the children is just incredible.”

The donor said her husband, whose picture is in the cockpit of the Endeavour, would have been very proud — if a little embarrassed — that his name is on the new building.

With the construction phase in the rearview, Rudolph said the center is now focused on completing installation of the galleries’ artifacts and hands-on installations. The Samuel Oschin Shuttle Gallery, which houses the Endeavour shuttle stack, is nearest to completion. In the two others, artifact installation is well underway.

The Korean Air Aviation Gallery explores the mechanics of flight and will display approximately 25 aircraft, from historical relics like the WWII “Vampire” jet to modern supersonic jet fighters. The Kent Kresa Space Gallery will feature a wide array of spacecraft, planetary probes, telescopes and more. Rudolph was especially excited about acquiring a SpaceX Cargo Dragon, which will further the air and space center’s goal to “show people that this isn’t all history.”

“There’s a lot of amazing things going on in aviation and space, and a lot of it happening in California,” the executive said.

The interactive installations complementing the artifacts include a 747 flight simulation and a 45-foot-long slide carrying visitors down to the bottom of the shuttle stack, which Rudolph himself has already ridden. His goal with these novelties was to both educate visitors about scientific principles and get children excited about the subject, which can get flattened in the traditional school system.

“Kids get turned off to science very early,” Rudolph said, but when they come to the science center, it’s like a whole new world opens up to them.

Rudolph said he expects to announce an opening date for the Samuel Oschin Air & Space Center this summer. He added that while it’s his intention to open by the 2028 L.A. Olympics, “we’re not really building this for a two-week athletic event.”

“We’re building this for the next 50 years to serve our community and inspire people,” he said.

As Rudolph made his way across the science center campus in March, he chuckled at the children bumping into him on their way to the exhibits.

“Future scientists, right?” he said.

In summer, it’s too hot. And in rain, the muddy dirt roads threaten to swallow your car.

But if you can hit Carrizo Plain National Monument on a spring day when the hills and grasslands are green and a few wildflowers remain in the meadows — well, you’re winning. And you’ll be seeing a lonely, raw corner of California that few people ever find.

The monument is about 38 miles long and 17 miles wide — hard to miss, you’d think. But it lies along the San Andreas fault in the usually dry hills between Bakersfield and Santa Maria, far from Interstate 5 or U.S. 101, about 170 driving miles northwest of Los Angeles.

Within the monument, most of the roads are gravel or dirt, and there is no drinkable water, no food, no gas and spotty cellphone coverage. The education center and two semi-primitive campgrounds feature vault toilets.

It’s almost perfect, in other words, for repelling crowds. Yet it’s pretty good as the centerpiece of an overnight road trip probing small towns and back roads of the western San Joaquin Valley and eastern San Luis Obispo County.

If you happen to arrive Friday, Carrizo staffers and volunteers will be celebrating the 25th anniversary of the monument, which was created from former ranch land under President Clinton. (Free tours and refreshments will be offered at the event, which takes place from 10 a.m. to 1 p.m. at the Guy L. Goodwin Education Center.) But next week might be greener, because rain on the plain is probable Saturday and Sunday.

For many visitors, Carrizo’s big draw is wildflowers. The grasslands and hillsides act as a vast, uncluttered canvas for their colors, which typically bloom in March and last through April. But every year is different, especially in this era of climate change. This year, after unusually heavy rains in February, Carrizo Plain erupted in a dramatic bloom in March, attracting several hundred visitors per day.

By the time my wife and I arrived in the first days of April, the flowers were past their peak, but the hills were still green and many meadows popped with yellow, purple and blue. If I’m reading my wildflowers handbook right, these were tidy tips, Goldfields, Owl’s Clover, thistle sage, Valley Larkspur, coreopsis, phacelia and hillside daisies.

Meanwhile, the 3,000-acre Soda Lake, which lies dusty, crusty, dry and white in summer, still had some water in it. Imagine the salty lake beds of Mono Lake, the Salton Sea or Death Valley’s Badwater, but surrounded by green hills. It was startling — the opposite of an oasis in the desert.

To get there, we drove north on I-5 into the San Joaquin Valley, then veered west by way of State Routes 166, 33 and 58, pausing for gas at Maricopa (population: 984).

Within the monument, we rambled along Soda Lake Road, admiring windmills, an old ranch house now reserved for bats, and a few hills dotted with lazy cows. (The monument is run by the Bureau of Land Management, which allows grazing.)

Looking a little bit more closely, you realize that the monument is all but torn in two by the San Andreas fault. On Elkhorn Road, you remember that those mountains to the east (the Temblor Range) are slowly lurching to the southeast. Meanwhile the Caliente Range — those mountains just to the west — are lurching the opposite way. The “offset” is growing by about 1.5 inches per year — at least, until the next big quake.

Slowly rolling through this scene, we spotted two critters scurrying along the roadside — fist-size creatures hopping on their back legs. These were probably giant kangaroo rats, a native species whose numbers have been growing since their listing as an endangered species in 1987.

We didn’t spot any blunt-nosed leopard lizards or San Joaquin Valley kit foxes (which eat giant kangaroo rats) but those species, too, are endangered and native to the area. Pronghorn antelope and Tule elk are out there, too, the experts say, along with California condors soaring overhead. We just saw crows, loitering on fence posts.

The Goodwin Education Center, the monument’s main gathering spot, is open Thursdays through Sundays, December through May. We looked at maps, got advice on where to go next and ate our sack lunches at a picnic table, marveling at those green slopes.

In this long valley, scientists have found signs of Native campsites up to 10,000 years old — a hint of how much wetter this area once was. Not far from the education center is a short hike to Painted Rock, a protected site that includes Native pictographs on a horseshoe-shaped sandstone formation. The red, black and white images go back 100-4,000 years. (We didn’t see them. From March through May, visitors can see the pictographs only on Saturday guided tours. From July 16 through February, visitors can book self-guided tours.)

After lunch we nosed around nearby Soda Lake, exited the north end of the monument, joined State Route 58 and headed west over a series of whoop-de-doos — those rises and falls in the road that will help you defy gravity, if you take them fast enough.

One of them, I realize now, was the San Andreas fault itself.

Through all of this, we saw no more than 15 or 20 people, cars included. Continuing from State Route 58, we joined State Route 41, watched oak trees and vineyards pop up and multiply, continued into Paso Robles and spent the night.

On the return trip we lingered for an hour or two in Santa Margarita (population: 1,149), checking out the Porch Cafe, the Barn (antiques) and the Giddy Up vintage goods and gift shop, which operates in a blue Quonset structure known as the Rainbow Hut.

“It’s just a sweet little town. So quiet,” said Holli Rae, a filmmaker and former Angeleno who opened the Giddy Up about two years ago. She moved north, she said, for “the nature, the animals, the deer, the birds. The creatures!”

Thanks to U.S. 101, we were home and grateful within three and a half hours.

Soon, we knew, summer will come and fry the Carrizo Plain until everything green is brown. Beginning June 1, in fact, the Goodwin Education Center will close for six months.

For a few more weeks, Angelenos, your window of opportunity is open.
