The Brief

A constellation of classified defense satellites built by the commercial company SpaceX is emitting a mysterious signal that may violate international standards, NPR has learned.

Satellites associated with the Starshield satellite network appear to be transmitting to the Earth's surface on frequencies normally used for doing the exact opposite: sending commands from Earth to satellites in space. The use of those frequencies to "downlink" data runs counter to standards set by the International Telecommunication Union, a United Nations agency that seeks to coordinate the use of radio spectrum globally.

Starshield's unusual transmissions have the potential to interfere with other scientific and commercial satellites, warns Scott Tilley, an amateur satellite tracker in Canada who first spotted the signals.

"Nearby satellites could receive radio-frequency interference and could perhaps not respond properly to commands — or ignore commands — from Earth," he told NPR.

Outside experts agree there's the potential for radio interference. "I think it is definitely happening," said Kevin Gifford, a computer science professor at the University of Colorado, Boulder who specializes in radio interference from spacecraft. But he said the issue of whether the interference is truly disruptive remains unresolved.

SpaceX and the U.S. National Reconnaissance Office, which operates the satellites for the government, did not respond to NPR's request for comment.

Caught by the wrong antenna

The discovery of the signal happened purely by chance.

Tilley regularly monitors satellites from his home in British Columbia as a hobby. He was working on another project when he accidentally triggered a scan of radio frequencies that are normally quiet.

"It was just a clumsy move at the keyboard," he said. "I was resetting some stuff and then all of a sudden I'm looking at the wrong antenna, the wrong band."

The band of the radio spectrum he found himself looking at, between 2025-2110 MHz, is reserved for "uplinking" data to orbiting satellites. That means there shouldn't be any signals coming from space in that range.

But Tilley's experienced eye noticed there appeared to be a signal coming down from the sky. It was in a part of the band "that should have nothing there," he said. "I got a hold of my mouse and hit the record button and let it record for a few minutes."

Tilley then took the data and compared it to a catalog of observations made by other amateur satellite trackers. These amateurs, located around the world, use telescopes to track satellites as they move across the sky and then share their positions in a database.

"Bang, up came an unusual identification that I wasn't expecting at all," he said. "Starshield."

Starshield is a classified version of SpaceX's Starlink satellites, which provide internet service around the world. The U.S. has reportedly paid more than $1.8 billion so far for the network, though little is known about it. According to SpaceX, Starshield conducts both Earth observation and communications missions.

Since May of 2024, the National Reconnaissance Office has conducted 11 launches of Starshield satellites in what it describes as its "proliferated system."

So far, the National Reconnaissance Office says it has launched more than 200 satellites as part of its "proliferated architecture" system to facilitate military Earth observations and communications missions.

"The NRO's proliferated system will increase timeliness of access, diversify communications pathways, and enhance resilience," the agency says of the system. "With hundreds of small satellites on orbit, data will be delivered in minutes or even seconds."

Tilley says he's detected signals from 170 of the Starshield satellites so far. All appear in the 2025-2110 MHz range, though the precise frequencies of the signals move around.

Signal's purpose in question

It's unclear what the satellite constellation is up to. Starlink, SpaceX's public satellite internet network, operates at much higher frequencies to enable the transmission of broadband data. Starshield, by contrast, is using a much lower frequency range that probably only allows for the transmission of data at rates closer to 3G cellular, Tilley says.

Tilley says he believes the decision to downlink in a band typically reserved for uplinking data could also be designed to hide Starshield's operations. The frequent shift in specific frequencies used could prevent outsiders from finding the signal.

Gifford says another possibility is that SpaceX was just taking advantage of a quiet part of the radio spectrum. Uplink transmissions from Earth to satellites are usually rare and brief, so these frequencies probably remain dark most of the time.

"SpaceX is smart and savvy," he says. It's possible they decided to just "do it and ask forgiveness later."

He notes it's unlikely the signals from Starshield have caused significant disruptions so far, otherwise other satellite operators would have complained.

Tilley told NPR he has decided to go public with his discovery because the world's satellite operators should be aware of what's happening.

"These are objects in classified orbits, which could potentially disturb other legitimate uses of space," he said.

More Californians filed claims for paid family leave last year than ever before since the state started offering the benefits two decades ago.

In 2025, more than 355,600 workers in the state took time to care for a sick family member or bond with a new child, up 16% from the year before, according to data LAist requested from the California Employment Development Department.

That change coincided with increased payments for workers who use paid leave. Workers in California can get up to eight weeks of paid leave — and now recoup 70–90% of their regular wages, up from 60–70% the year prior.

“The program continues to grow,” said Anne Chapuis, a spokesperson for EDD. While she said 2025 represents their largest year to date, the rise or fall of claims “can sometimes be attributed to a combination of factors including awareness, demand, and eligibility.”

California became the first state to enact a paid family leave program in 2004. At the time, workers only got 55% of their wages and six weeks of paid leave.

Jenya Cassidy, executive director of the advocacy group California Work & Family Coalition, said her organization is still working to understand why there’s a rise in claims, but have anecdotally heard of people taking it because of the increase. The group co-sponsored the 2022 legislation that increase payments, after hearing that many low-income earners couldn’t afford to take leave. Research has shown that paid family leave benefits help a mother and baby’s health.

“Sixty percent of their income wasn't enough to pay their bills, and so many people are living on the edge in this state especially,” Cassidy said.

She said there was also more publicity about the paid family leave program last year because of the payment increase.

“There was a little bit of hubbub about this wage replacement [increase], so I do think raising awareness about the affordability of taking it is a key thing,” she said. “People hearing it anecdotally, seeing it in the news, I think that kind of has an impact.”

The state Employment Development Department says the paid family leave program, which started in 2004, continues to grow.

There are also cultural and general shifts around family leave, said Jessica Mason, senior policy analyst for economic justice at the National Partnership for Women & Families.

“For millennials and Gen Z, there's a little bit more of an assumption that everybody's going to be doing caregiving, everybody's going to be involved in parenting, and those norms do kind of shift over time,” she said.

For example, more dads in California are taking paid leave time, recent state data show.

Mason recently worked on a report that found 1 in 3 private sector workers nationwide now have access to a paid family leave program, with 14 states having paid family leave laws. But because California is such a big state, it plays a huge role in that statistic, she said. The program covers more than 18 million residents.

“In California, about 97% of the private sector workforce is potentially eligible for paid leave … that's really at the top end of all of the states,” she said.

How the state's paid family leave program works

The family leave program in California is paid through the State Disability Insurance program. Workers pay into the program through a deduction on their paycheck usually labeled as “CADSI.”

To be eligible for paid family leave in California, a worker needs to have earned at least $300 in wages in a “base period” (5-18 months before a claim).

Eligible workers who make less than about $66,000 a year can get 90% of their wages, and workers who make above that recieve 70% while on leave.

For the first time since Los Angeles County began tracking the data, fewer unhoused residents died on the streets in 2024, according to a report released Tuesday.

About 2,208 people experiencing homelessness died in the county that year, 300 fewer than the previous year, according to the report from the county Department of Public Health.

The report also showed the mortality rate — which is the number of deaths per 100,000 unhoused residents — decreased by 10%.

Health officials credit drug overdose prevention efforts for some of that decline, including greater distribution of naloxone, a medication that can reverse the effects of an opioid overdose.

There was a 21% decrease in the drug overdose death rate among unhoused residents, according to the report.

Still, an average of six people experiencing homelessness died each day in L.A. County throughout 2024. People without stable housing face mortality rates over four times higher than the general population.

Authorities note that number is still too high.

"These disparities reflect systemic barriers — lack of safe housing, limited access to culturally responsive healthcare, unsafe environments, and the ongoing effects of trauma, discrimination, and social inequities," Barbara Ferrer, director of the L.A. County Department of Public Health, wrote in the report.

She said she expects the work to get harder, with major state and regional funding reductions to some homeless services this year.

“Just as we are beginning to see positive momentum on homeless mortality reduction, we are at risk of losing precious ground,” Ferrer continued.

County health officials made several recommendations in the report, including providing more access to shelter and housing, mental health and substance use treatment services.

Drug overdose deaths 

The annual report relies on state death records, county medical examiner data and population estimates from the region’s annual point-in-time homeless count.

More than 75,000 people were estimated to be experiencing homelessness in L.A. County in 2024, according to the Los Angeles Homeless Services Authority’s official count that year.

Despite some decreases, drug overdose remained the leading cause of death among people experiencing homelessness in Los Angeles County and accounted for 40% of all deaths among that population.

In 2024, 884 unhoused people died of drug overdoses in L.A. County. That was down from 1,140 deaths in 2023, according to the report.

Unhoused residents were 46 times more likely to die of drug overdose than the general population. The report notes the overdose death rate is still about twice as high as it was in 2019.

Many of the deaths involved fentanyl, a synthetic opioid, but for the first time they accounted for a lower percentage than in the previous year — 59% in 2024 and 70% in 2023, according to the data.

Most overdose deaths involve multiple drugs, according to the county. The percentage of deaths in which methamphetamine was a factor remained relatively steady — 80% in 2024 and 79% in 2023.

Overdose deaths involving only methamphetamine rose from 19% in 2023 to 27% in 2024.

Other causes of death

The Public Health Department is tracking other leading causes of death for unhoused residents. In 2024, the rates for coronary heart disease and homicide among unhoused Angelenos went down, while transportation-related deaths and suicides went up.

• Coronary heart disease: The second leading cause of death among L.A. County’s unhoused population continued to be coronary heart disease, which accounted for 14% of unhoused deaths in 2024. The previous year, it was 15%.
  
• Transportation-related deaths: Traffic-related injury remained the third leading cause of death among all unhoused L.A. County residents, accounting for 11% of those fatalities. That’s up from 8% the previous year. After a two-year plateau, the traffic injury mortality rate increased by 25% to 315 deaths per 100,000 unhoused people. About 230 unhoused pedestrians or cyclists were killed in traffic collisions in 2024. They were 24 times more likely to die from traffic-related injuries than the overall L.A. County population.
  
• Homicide: Homicide was the fourth leading cause of death among unhoused people in L.A. County in 2024. That year, 105 unhoused people were victims of homicide, according to county data. That’s compared to 124 the previous year. Unhoused Angelenos were 14 times more likely to die by homicide than the general population.
  
• Suicide: The suicide rate among L.A.’s homeless population increased by 21% in 2024. County data show 80 unhoused L.A. County residents died by suicide in 2024. That was 4% of all recorded deaths among unhoused residents, up from 3% the previous year. Unhoused residents were 13 times more likely to die by suicide than Angelenos in general.

Public Health recommendations

The Department of Public Health made several recommendations to prevent premature deaths and continue slowing the mortality rate among unhoused people in the region.

They included:

• Ensuring access to affordable housing and health insurance.
• Ensuring that housing options support harm reduction, overdose prevention and substance use treatment.
• Expanding comprehensive primary and preventive care services for unhoused people.
• Conducting a detailed analysis of 2024 traffic injury deaths among unhoused residents to inform policy interventions.

LAX officials are considering a proposal Tuesday to increase the fees rideshare companies are charged to access the airport.

Currently, rideshare companies like Uber and Lyft generally pass a $4 to $5 airport fee along to their customers. You might see this listed as a line item on your receipt as an “LAX Airport Surcharge.”

But the Los Angeles World Airports Board of Commissioners could vote to increase that fee by as much as $2 to $8 depending on where the rideshare picks you up or drops you off.

The idea behind the proposal is to encourage the use of the long-awaited, much-delayed and over-budget Automated People Mover once it opens and decrease congestion in the central terminal area, the area of the airport that’s also known as the horseshoe.

David Reich, a deputy executive director for the city agency that manages the airport, told LAist that if the proposal is approved, LAX doesn’t plan on increasing the fee until after the Automated People Mover opens, which could be later this year.

The proposed increases

When the Automated People Mover opens, there will be new curb space for drop-off and pick-up. Known as the “ground transport center,” this new curb space will be a 4-minute trip from the terminal area via the Automated People Mover, according to Reich.

LAX-it will shut down as a rideshare and taxi lot once the train opens, Reich said.

If the proposal is approved, getting an Uber or Lyft to and from the ground transport center will come with a $6 airport fee.

Even once the Automated People Mover opens, you will still be able to get rides directly to and from the curbs along the horseshoe, but they will come with a $12 fee.

The proposed increases would also apply to taxi and limousine services, which currently operate under a slightly different fee structure than rideshare companies.

The increased fees are expected to generate as much as $100 million in the first year the Automated People Mover is usable, according to a report to the board.

Why the different fees for the different locations?

In a report to the board, Reich said the Automated People Mover represents a "significant investment” that aims to “fundamentally reshape how vehicles move through the airport.”

The idea behind having a higher fee for direct access to the curbs along the horseshoe is to encourage “use of new, high-capacity infrastructure” and preserve central terminal access for trips “that most require it.”

Uber is trying to fight the increases

Uber is trying to mobilize the public to fight the proposed fee increases.

“Raising the LAX rideshare fee from $5 to $12 at the curb would punish travelers, working families, and seniors who depend on affordable, reliable transportation,” Danielle Lam, the head of local California policy for Uber, said in a statement.

On Monday, Uber sent an email to passengers who recently used the rideshare service, urging them to write to city officials to “stop this massive fee hike.”

Lyft has not responded to a request for comment.

Ten state lawmakers who are members of the L.A. County delegation sent a letter on Monday to the board expressing their “strong opposition” to the proposed increases.

“Many Angelenos rely on a mix of options, including rideshare services and friends or family dropping off loved ones,” the legislators wrote in the letter. “Managing congestion cannot realistically rely on steep fee increases for certain transportation options.”

Eight of the 10 legislators who signed the letter have received campaign contributions from Uber or Lyft, according to an LAist analysis of state campaign contribution data.

Other ways to access the airport

Now is probably a good time to remind folks that there are other ways to get to the airport that don’t involve rideshares, taxis or even lifts from families and friends.

The FlyAway bus offers regularly scheduled rides from the airport to Union Station in downtown L.A. and Van Nuys. You can see the schedules here. 

Last year, the countywide transportation agency unveiled the LAX/Metro Transit center, which is accessible from the C and K rail lines and several bus routes. For now, an LAX shuttle is bringing travelers from the station to the airport. It will be one of the stops on the Automated People Mover once it opens.
