Space shuttle Endeavour's giant orange external tank begins final journey

At long last, the final journey of the last space shuttle ever built, Endeavour, and its giant orange external tank are expected to begin this month — the capstone to a historic journey to an ambitious museum exhibit in Los Angeles.

It’ll be a momentous occasion for the California Science Center, the state-run museum just south of downtown L.A., which is building the 20-story Samuel Oschin Air and Space Center to house Endeavour. Anticipation has been building for more than a decade for the new museum wing, after NASA’s decision in 2011 to send Endeavour to L.A. and the orbiter’s cross-country journey in 2012, flying over the Hollywood sign before undertaking a three-day journey through city streets to its new home.

Unlike any other exhibit showcasing a retired space shuttle, Endeavour in L.A. will be configured in a full-stack arrangement, pointing to the stars, as if ready for launch.

Barring any weather delays, starting next week, the 65,000-pound, 154-foot-long giant orange external tank is expected to be moved and then lifted up from its current horizontal position into a vertical orientation, where it’ll be attached to the solid rocket boosters that have already been installed.

Then, no earlier than the end of the month, the space shuttle orbiter itself, Endeavour, will then be lifted from its horizontal position to its vertical position, and be attached to the external tank. It’ll be the first time a shuttle designed for space has been assembled vertically outside of a NASA or Air Force facility.

The operation will be a sight to see, and the key moments of the lift of the external tank and Endeavour will be streamed online by the California Science Center. The cranes that will lift the spacecraft are quite tall — the tallest of which will be about the height of City Hall.

“Show time!” said Jeffrey Rudolph, president of the California Science Center.

The prelude to the external tank’s big lift is scheduled for Jan. 10, when the it will be moved by self-propelled modular transporters — similar to the ones used to move Endeavour through city streets in 2012 — down State Drive to the new museum wing’s construction site. The journey will take about two hours, past the science center and the Exposition Park Rose Garden.

Then, on the evening of Jan. 11 and into the next morning, the external tank is to be lifted, starting sometime after 10 p.m. Because the move is taking place outdoors, any significant winds could lead to delays in the big move, and the museum doesn’t want a very big thing swinging off a crane in significant winds.

“The trend, at least in December, was for the winds to die down about 10 p.m. and pick back up about 4 a.m. Assuming that holds into early January, we’ll try taking advantage of that six-hour window to lift the tank and get it in to the pit,” said Dennis Jenkins, project director for the Samuel Oschin Air and Space Center.

Two cranes will be used initially to lift up the external tank from its horizontal position. Then, the external tank will be slowly turned upright to a vertical orientation, and one of the cranes will be disconnected. The other crane will then lift the tank into its final position.

The external tank will then be attached to components that were installed in recent months — the twin solid rocket boosters, which began to be installed in a months-long process that started over the summer. At liftoff, the white rocket boosters were set underneath the shuttle’s wings and produced more than 80% of the lift.

The 15-story orange external tank, the last of its kind in existence, arrived in Los Angeles in 2016, on a journey by sea through the Panama Canal and into Marina del Rey, before also lumbering through the streets to the Science Center. During launches, the external tank carried propellants — liquid oxygen and liquid hydrogen — that powered the space shuttle’s three main engines to help bring the shuttle into orbit.

After the external tank is put into position, work will begin to move Endeavour out of its existing exhibit space, the temporary hangar known as the Samuel Oschin Space Shuttle Endeavour Pavilion, where the orbiter had been on display for about 11 years, until it closed on New Year’s Eve.

The hangar is being dismantled to make way for Endeavour’s move. Later this month, Endeavour will begin to be moved out of the hangar, on the western edge of the science center, Rudolph said.

It’ll first be rolled onto the lawn just north of the Los Angeles Memorial Coliseum and south of the Natural History Museum of Los Angeles County.

Then, the orbiter will move down State Drive. The move will be tricky: At one point, Endeavour will need to be jacked up — to avoid striking a building — moved and then jacked back down for the rest of the journey.

Weather permitting, before the end of the month, Endeavour will undertake its own lift into place. Hopefully, that lift will also be a one-night operation.

Once Endeavour is in place, the rest of the museum will be built around it, followed by the time it will take to install exhibits. It could be a few years before the new museum is open to the public.

The shuttle project, estimated to cost $400 million, will reshape the skyline around the California Science Center, whose roots stem from 110 years ago as a site for exhibiting agricultural and industrial projects. The site became the California Museum of Science and Industry in 1951, and reopened as the California Science Center in 1998.

The new aerospace museum wing is named for Samuel Oschin, the late Los Angeles businessman and philanthropist, whose name is also on the Griffith Observatory planetarium and the Cedars-Sinai Medical Center cancer institute. Financial contributions that came from the Mr. and Mrs. Samuel Oschin Family Foundation have been transformational to building the new museum wing, which broke ground in mid-2022.

The space shuttle’s arrival in California was a homecoming for Endeavour, which rolled off Rockwell International’s production line in Palmdale in 1991, replacing Challenger, which exploded shortly after launch in 1986, killing the seven aboard. Southern California played a crucial role in the shuttles’ development, which pumped hundreds of millions of dollars into the economy and became a source of pride for the region’s aerospace industry.

Endeavour flew 25 missions in space before its final flight in 2011, eight years after another shuttle, Columbia, disintegrated on reentry in 2003, and the shuttle fleet was set for retirement.

Among Endeavour’s most notable missions was successfully repairing the Hubble Space Telescope and helping complete construction of the International Space Station.

Diablo Canyon clears last California permit hurdle to keep running

Diablo Canyon clears last California permit hurdle to keep running

Central Coast Water authorities approved waste discharge permits for Diablo Canyon nuclear plant Thursday, making it nearly certain it will remain running through 2030, and potentially through 2045.

The Pacific Gas & Electric-owned plant was originally supposed to shut down in 2025, but lawmakers extended that deadline by five years in 2022, fearing power shortages if a plant that provides about 9 percent the state’s electricity were to shut off.

In December, Diablo Canyon received a key permit from the California Coastal Commission through an agreement that involved PG&E giving up about 12,000 acres of nearby land for conservation in exchange for the loss of marine life caused by the plant’s operations.

Today’s 6-0 vote by the Central Coast Regional Water Board approved PG&E’s plans to limit discharges of pollutants into the water and continue to run its “once-through cooling system.” The cooling technology flushes ocean water through the plant to absorb heat and discharges it, killing what the Coastal Commission estimated to be two billion fish each year.

The board also granted the plant a certification under the Clean Water Act, the last state regulatory hurdle the facility needed to clear before the federal Nuclear Regulatory Commission (NRC) is allowed to renew its permit through 2045.

The new regional water board permit made several changes since the last one was issued in 1990. One was a first-time limit on the chemical tributyltin-10, a toxic, internationally-banned compound added to paint to prevent organisms from growing on ship hulls.

Additional changes stemmed from a 2025 Supreme Court ruling that said if pollutant permits like this one impose specific water quality requirements, they must also specify how to meet them.

The plant’s biggest water quality impact is the heated water it discharges into the ocean, and that part of the permit remains unchanged. Radioactive waste from the plant is regulated not by the state but by the NRC.

California state law only allows the plant to remain open to 2030, but some lawmakers and regulators have already expressed interest in another extension given growing electricity demand and the plant’s role in providing carbon-free power to the grid.

Some board members raised concerns about granting a certification that would allow the NRC to reauthorize the plant’s permits through 2045.

“There’s every reason to think the California entities responsible for making the decision about continuing operation, namely the California [Independent System Operator] and the Energy Commission, all of them are sort of leaning toward continuing to operate this facility,” said boardmember Dominic Roques. “I’d like us to be consistent with state law at least, and imply that we are consistent with ending operation at five years.”

Other board members noted that regulators could revisit the permits in five years or sooner if state and federal laws changes, and the board ultimately approved the permit.

Deadly bird flu found in California elephant seals for the first time

Deadly bird flu found in California elephant seals for the first time

The H5N1 bird flu virus that devastated South American elephant seal populations has been confirmed in seals at California’s Año Nuevo State Park, researchers from UC Davis and UC Santa Cruz announced Wednesday.

The virus has ravaged wild, commercial and domestic animals across the globe and was found last week in seven weaned pups. The confirmation came from the U.S. Department of Agriculture’s National Veterinary Services Laboratory in Ames, Iowa.

“This is exceptionally rapid detection of an outbreak in free-ranging marine mammals,” said Professor Christine Johnson, director of the Institute for Pandemic Insights at UC Davis’ Weill School of Veterinary Medicine. “We have most likely identified the very first cases here because of coordinated teams that have been on high alert with active surveillance for this disease for some time.”

Since last week, when researchers began noticing neurological and respoiratory signs of the disease in some animals, 30 seals have died, said Roxanne Beltran, a professor of ecology and evolutionary biology at UC Santa Cruz. Twenty-nine were weaned pups and the other was an adult male. The team has so far confirmed the virus in only seven of the dead pups.

Infected animals often have tremors convulsions, seizures and muscle weakness, Johnson said.

Beltran said teams from UC Santa Cruz, UC Davis and California State Parks monitor the animals 260 days of the year, “including every day from December 15 to March 1” when the animals typically come ashore to breed, give birth and nurse.

The concerning behavior and deaths were first noticed Feb. 19.

“This is one of the most well-studied elephant seal colonies on the planet,” she said. “We know the seals so well that it’s very obvious to us when something is abnormal. And so my team was out that morning and we observed abnormal behaviors in seals and increased mortality that we had not seen the day before in those exact same locations. So we were very confident that we caught the beginning of this outbreak.”

In late 2022, the virus decimated southern elephant seal populations in South America and several sub-Antarctic Islands. At some colonies in Argentina, 97% of pups died, while on South Georgia Island, researchers reported a 47% decline in breeding females between 2022 and 2024. Researchers believe tens of thousands of animals died.

More than 30,000 sea lions in Peru and Chile died between 2022 and 2024. In Argentina, roughly 1,300 sea lions and fur seals perished.

At the time, researchers were not sure why northern Pacific populations were not infected, but suspected previous or milder strains of the virus conferred some immunity.

The virus is better known in the U.S. for sweeping through the nation’s dairy herds, where it infected dozens of dairy workers, millions of cows and thousands of wild, feral and domestic mammals. It’s also been found in wild birds and killed millions of commercial chickens, geese and ducks.

Two Americans have died from the virus since 2024, and 71 have been infected. The vast majority were dairy or commercial poultry workers. One death was that of a Louisiana man who had underlying conditions and was believed to have been exposed via backyard poultry or wild birds.

Scientists at UC Santa Cruz and UC Davis increased their surveillance of the elephant seals in Año Nuevo in recent years. The catastrophic effect of the disease prompted worry that it would spread to California elephant seals, said Beltran, whose lab leads UC Santa Cruz’s northern elephant seal research program at Año Nuevo.

Johnson, the UC Davis researcher, said the team has been working with stranding networks across the Pacific region for several years — sampling the tissue of birds, elephant seals and other marine mammals. They have not seen the virus in other California marine mammals. Two previous outbreaks of bird flu in U.S. marine mammals occurred in Maine in 2022 and Washington in 2023, affecting gray and harbor seals.

The virus in the animals has not yet been fully sequenced, so it’s unclear how the animals were exposed.

“We think the transmission is actually from dead and dying sea birds” living among the sea lions, Johnson said. “But we’ll certainly be investigating if there’s any mammal-to-mammal transmission.”

Genetic sequencing from southern elephant seal populations in Argentina suggested that version of the virus had acquired mutations that allowed it to pass between mammals.

The H5N1 virus was first detected in geese in China in 1996. Since then it has spread across the globe, reaching North America in 2021. The only continent where it has not been detected is Oceania.

Año Nuevo State Park, just north of Santa Cruz, is home to a colony of some 5,000 elephant seals during the winter breeding season. About 1,350 seals were on the beach when the outbreak began. Other large California colonies are located at Piedras Blancas and Point Reyes National Sea Shore. Most of those animals — roughly 900 — are weaned pups.

It’s “important to keep this in context. So far, avian influenza has affected only a small proportion of the weaned at this time, and there are still thousands of apparently healthy animals in the population,” Beltran said in a press conference.

Public access to the park has been closed and guided elephant seal tours canceled.

Health and wildlife officials urge beachgoers to keep a safe distance from wildlife and keep dogs leashed because the virus is contagious.

When slowing down can save a life: Training L.A. law enforcement to understand autism

When slowing down can save a life: Training L.A. law enforcement to understand autism

Kate Movius moved among a roomful of Los Angeles County sheriff’s deputies, passing out a pop trivia quiz and paper prism glasses.

She told them to put on the vision-distorting glasses, and to write with their nondominant hand. As they filled out the tests, Movius moved about the City of Industry classroom pounding abruptly on tables. Then came the cowbell. An aide flashed the overhead lights on and off at random. The goal was to help the deputies understand the feeling of sensory overwhelm, which many autistic people experience when incoming stimulation exceeds their capacity to process.

“So what can you do to assist somebody, or de-escalate somebody, or get information from someone who suffers from a sensory disorder?” Movius asked the rattled crowd afterward. “We can minimize sensory input. … That might be the difference between them being able to stay calm and them taking off.”

Movius, founder of the consultancy Autism Interaction Solutions, is one of a growing number of people around the U.S. working to teach law enforcement agencies to recognize autistic behaviors and ensure that encounters between neurodevelopmentally disabled people and law enforcement end safely.

She and City of Industry Mayor Cory Moss later passed out bags filled with tools donated by the city to aid interactions: a pair of noise-damping headphones to decrease auditory input, a whiteboard, a set of communication cards with words and images to point to, fidget toys to calm and distract.

“The thing about autistic behavior when it comes to law enforcement is a lot of it may look suspicious, and a lot of it may feel very disrespectful,” said Movius, who is also the parent of an autistic 25-year-old man. Responding officers, she said, “are not coming in thinking, ‘Could this be a developmentally disabled person?’ I would love for them to have that in the back of their minds.”

Autism spectrum disorder is a developmental condition that manifests differently in nearly every person who has it. Symptoms cluster around difficulties in communication, social interaction and sensory processing.

An autistic person stopped by police might hold the officer’s gaze intensely or not look at them at all. They may repeat a phrase from a movie, repeat the officer’s question or temporarily lose their ability to speak. They might flee.

All are common involuntary responses for an autistic person in a stressful situation, which a sudden encounter with law enforcement almost invariably is. To someone unfamiliar with the condition, all could be mistaken for intoxication, defiance or guilt.

Autism rates in the U.S. have increased nearly fivefold since the Centers for Disease Control began tracking diagnoses in 2000, a rise experts attribute to broadening diagnostic criteria and better efforts to identify children who have the condition.

The CDC now estimates that 1 in 31 U.S. 8-year-olds is autistic. In California, the rate is closer to 1 in 22 children.

As diverse as the autistic population is, people across the spectrum are more likely to be stopped by law enforcement than neurotypical peers.

About 15% of all people in the U.S. ages 18 to 24 have been stopped by police at some point in their lives, according to federal data. While the government doesn’t track encounters for disabled people specifically, a separate study found that 20% of autistic people ages 21 to 25 have been stopped, often after a report or officer observation of a person behaving unusually.

Some of these encounters have ended in tragedy.

In 2021, Los Angeles County sheriff’s deputies shot and permanently paralyzed a deaf autistic man after family members called 911 for help getting him to a hospital.

Isaias Cervantes, 25, had become distressed about a shopping trip and started pushing his mother, his family’s attorney said at the time. He resisted as two deputies attempted to handcuff him and one of the deputies shot him, according to a county report.

In 2024, Ryan Gainer’s family called 911 for support when the 15-year-old became agitated. Responding San Bernardino County sheriff‘s deputies shot and killed him outside his Apple Valley home.

Last year, police in Pocatello, Idaho, shot Victor Perez, 17, through a chain-link fence after the nonspeaking teenager did not heed their shouted commands. He died from his injuries in April.

As early as 2001, the FBI published a bulletin on police officers’ need to adjust their approach when interacting with autistic people.

“Officers should not interpret an autistic individual’s failure to respond to orders or questions as a lack of cooperation or as a reason for increased force,” the bulletin stated. “They also need to recognize that individuals with autism often confess to crimes that they did not commit or may respond to the last choice in a sequence presented in a question.”

But a review of multiple studies last year by Chapman University researchers found that while up to 60% of officers have been on a call involving an autistic person, only 5% to 40% had received any training on autism.

In response, universities, nonprofits and private consultants across the U.S. have developed curricula for law enforcement on how to recognize autistic behaviors and adapt accordingly.

The primary goal, Movius told deputies at November’s training session, is to slow interactions down to the greatest extent possible. Many autistic people require additional time to process auditory input and verbal responses, particularly in unfamiliar circumstances.

If at all possible, Movius said, wait 20 seconds for a response after asking a question. It may feel unnaturally long, she acknowledged. But every additional question or instruction fired in that time — what’s your name? Did you hear me? Look at me. What’s your name? — just decreases the likelihood that a person struggling to process will be able to respond at all.

Moss’ son, Brayden, then 17, was one of several teenagers and young adults with autism who spoke or wrote statements to be read to the deputies. The diversity of their speech patterns and physical mannerisms showed the breadth of the spectrum. Some were fluently verbal, while others communicated through signs and notes.

“This population is so diverse. It is so complicated. But if there’s anything that we can show [deputies] in here that will make them stop and think, ‘Hey, what if this is autism?’ … it is saving lives,” Moss said.

Some disability advocates cautioned that it takes more than isolated training sessions to ensure encounters end safely.

Judy Mark, co-founder and president of the nonprofit Disability Voices United, says she trained thousands of officers on safe autism interactions but stopped after Cervantes’ shooting. She now urges families concerned about an autistic child’s safety to call an ambulance rather than law enforcement.

“I have significant concern about these training sessions,” Mark said. “People get comfort from it, and the Sheriff’s Department can check the box.”

While not a panacea, supporters argue that a brief course is better than no preparation at all. Some years ago, Movius received a letter from a man whose profoundly autistic son slipped away as the family loaded their car at the beach. He opened the unlocked door of a police vehicle, climbed into the back and began to flail in distress.

Though surprised, the officer seated at the wheel de-escalated the situation and helped the young man find his family, the father wrote to Movius. He had just been to her training.
