The Ex-Patients’ Club

The Ex-Patients’ Club

On a recent Friday morning, Daniel, a lawyer in his early 40s, was in a Zoom counseling session describing tapering off lithium. Earlier that week he had awakened with racing thoughts, so anxious that he could not read, and he counted the hours before sunrise.

At those moments, Daniel doubted his decision to wean off the cocktail of psychiatric medications which had been part of his life since his senior year in high school, when he was diagnosed with bipolar disorder.

Was this his body adjusting to the lower dosage? Was it a reaction to the taco seasoning he had eaten the night before? Or was it what his psychiatrist would have called it: a relapse?

“It still does go to the place of — what if the doctors are right?” said Daniel.

On his screen, Laura Delano nodded sympathetically.

Ms. Delano is not a doctor; her main qualification, she likes to say, is having been “a professional psychiatric patient between the ages of 13 and 27.” During those years, when she attended Harvard and was a nationally ranked squash player, she was prescribed 19 psychiatric medications, often in combinations of three or four at a time.

Then Ms. Delano decided to walk away from psychiatric care altogether, a journey she detailed in a new memoir, “Unshrunk: A Story of Psychiatric Treatment Resistance.” Fourteen years after taking her last psychotropic drug, Ms. Delano projects a radiant good health that also serves as her argument — living proof that, all along, her psychiatrists were wrong.

Since then, to the alarm of some physicians, an online DIY subculture focused on quitting psychiatric medications has expanded and begun to mature into a service industry.

Ms. Delano is a central figure in this shift. From her house outside Hartford, Conn., she offers coaching to paying clients like Daniel. But her ambitions are grander. Through Inner Compass Initiative, the nonprofit she runs with her husband, Cooper Davis, she hopes to provide support to a large swath of people interested in reducing or quitting psychiatric medications.

“People are realizing, ‘I don’t actually need to go find a doctor who knows how to do this,’” she said. In fact, she added, they may not even need to tell their doctor.

“That sounds quite radical,” she allowed. “I imagine a lot of people would hear that and be, like, ‘That’s dangerous.’ But it’s just been the reality for thousands and thousands of people out there who have realized, ‘I have to stop thinking that psychiatry is going to get me out of this situation.’”

Increasingly, many psychiatrists agree that the health care system needs to do a better job helping patients get off psychotropic medications when they are ineffective or no longer necessary. The portion of American adults taking them approached 25 percent during the pandemic, according to government data, more than triple what it was in the early 1990s.

But they also warn that quitting medications without clinical supervision can be dangerous. Severe withdrawal symptoms can occur, and so can a relapse, and it takes expertise to tease them apart. Psychosis and depression may flare up, and the risk of suicide rises. And for people with the most disabling mental illnesses, like schizophrenia, medication remains the only evidence-based treatment.

“What makes tremendous sense for Laura” and “millions of people who are over-diagnosed and over-treated makes no sense at all for people who can’t get medicine,” said Dr. Allen Frances, a professor emeritus of psychiatry at Duke University School of Medicine.

“Laura does not generalize to the person with chronic mental illness and has a clear chance of ending up homeless or in the hospital,” he said. “Those people don’t wind up looking like Laura when they are taken off medication.”

It was hard to say what a life after psychiatric treatment would look like for Daniel, who asked to be identified by only his first name to discuss his mental health history. He has been tapering off lithium for nine months under the care of a nurse-practitioner, and settled, for the moment, at 450 milligrams, half his original dose.

He had become convinced that the drugs were harming him. And yet, when the waves of anxiety and insomnia hit him, he wavered. Daniel is a litigator. He had depositions coming up at work, and the way his thoughts were jumping around scared him.

“I can’t avoid that fear, you know, ‘I’m doing a lot better on less lithium, but it’s just going to fall apart again,’ ” he told Ms. Delano.

Ms. Delano listened quietly, and then told him a story from her own life.

It happened a few months after she quit the last of her medications. On a night walk, her senses built to a crescendo. Christmas lights seemed to be winking messages at her. She recognized hypomania, a symptom of bipolar disorder, and the thought crossed her mind: The doctors had been right. Then some kind of force moved through her, and she realized that these sensations were not a sign of mental illness at all.

“I was like, ‘This is you healing,’ ” she said. “This is you, coming alive.”

She told Daniel that she couldn’t promise he would never have another manic episode. But she could tell him that her own fear had dissipated, over time. “I get to write my own story from here on in,” she said. “And that takes an act of faith.”

Peer support around withdrawing from psychiatric medications dates back 25 years, to the early days of digital social networks.

Adele Framer, a retired information architect from San Francisco, discovered such groups in 2005 while going through a difficult withdrawal from Paxil. At the time, Ms. Framer said, physicians dismissed severe withdrawal as “basically impossible.”

People circulated between the groups, comparing “tapers” in “a viral information-sharing process,” said Ms. Framer, who launched her own site, Surviving Antidepressants, in 2011. Users on her site exchanged highly technical tapering protocols, with dose reductions so tiny that they sometimes required syringes and precision scales.

Dr. Mark Horowitz, an Australian psychiatrist, discovered Ms. Framer’s site in 2015 and used the peer advice he found to taper off Lexapro himself.

“At that point, I understood who the experts were,” he said. “I have six academic degrees, I have a Ph.D., I know how antidepressants work, and I was taking advice from retired engineers and housewives on a peer support site to help come off the drugs.”

In recent years, mainstream psychiatry has begun to acknowledge the need for more support for patients getting off medications.

This is most visible in Britain, whose health service has updated its guidance for clinicians to acknowledge withdrawal and recommend regular reviews to discontinue unnecessary medications. In 2024, the Maudsley Prescribing Guidelines in Psychiatry, a respected clinical handbook, issued its first “de-prescribing” volume. Dr. Horowitz was one of its authors.

There are early signs of movement in the United States, as well. Dr. Jonathan E. Alpert, chairman of the American Psychiatric Association’s Council on Research, said that the group plans to issue its own de-prescribing guide.

The American Society of Clinical Psychopharmacology is working on a guide to help doctors identify when a medication should be discontinued. “There has never been an incentive in industry to tell people when to stop using their product,” said Dr. Joseph F. Goldberg, the group’s president. “So it really falls to the nonindustry community to ask those questions.”

Dr. Gerard Sanacora, the director of the Yale Depression Research Program, said there are practical reasons the current health care system “doesn’t provide much support” for patients seeking to reduce medications: Relapse prevention can be time-consuming, and many physicians are only reimbursed for 15-minute “med management” appointments.

But he said it was important that trained clinicians still have a role. In a “taper,” patients encounter difficulties of two kinds: withdrawal, and the relapse of underlying conditions. It takes skill to distinguish between them, he said, and a licensed practitioner guarantees “some level of minimum competency” during a period of especially high risk.

“The main thing is, they can worsen and kill themselves,” he said of patients.

Ms. Delano entered the conversation in 2010, when she began blogging about her life. She was 27 years old, living with her aunt and uncle and attending day treatment at McLean Hospital in Massachusetts. Her platform was Mad in America, a website where a range of former psychiatric patients exchanged stories about their treatment.

Within that subculture, Ms. Delano stood out for her eloquence and charisma. She had grown up in Greenwich, Conn., where she was a top student and standout athlete. A relative of Franklin D. Roosevelt, she was presented as a debutante on two successive nights at New York’s Waldorf Astoria and Plaza hotels.

On her blog, and later in a 10,000-word profile in The New Yorker, she described the shadow plot of her psychiatric treatment.

In ninth grade, she was diagnosed with bipolar disorder and prescribed Depakote and Prozac. In college, her pharmacologists added Ambien and Provigil. Over the years, this list expanded, but she still seemed to be getting worse. Four times she was so desperate that she checked herself into psychiatric hospitals. At 25, she made a harrowing attempt at suicide.

Then, at 27, she picked up a book by the journalist Robert Whitaker, “Anatomy of an Epidemic: Magic Bullets, Psychiatric Drugs, and the Astonishing Rise of Mental Illness in America.” In the book, Mr. Whitaker proposed that the increasing use of psychotropic medications was to blame for the rise in psychiatric disorders. In scientific journals, reviewers dismissed Mr. Whitaker’s analysis as polemical, cherry-picking data to support a broad, oversimplified argument.

But for Ms. Delano, it was an epiphany. She mentally reviewed her treatment history and came to a radical conclusion. “I’d been confronted with something I’d never considered,” she writes in “Unshrunk.”“What if it wasn’t treatment-resistant mental illness that had been sending me ever deeper into the depths of despair and dysfunction, but the treatment itself?”

She quit five drugs over the six months that followed, under the guidance of a psychopharmacologist. She describes a brutal withdrawal, complete with constipation, diarrhea, aches, spasms and insomnia, as “angsty energy that had lived in me for years began to scratch viciously beneath the surface of my skin.”

But she also experienced a kind of awakening. “I knew it as clear as day, the second it occurred to me,” she writes. “I was ready to stop being a psychiatric patient.”

Born in 1983, five years before Prozac entered the market, Ms. Delano was part of the first large wave of Americans to be prescribed medications in their teens. Many readers recognized, in her blog entries, elements of their own stories — the way a diagnosis had become part of their identities, the way a single prescription had expanded into a cocktail.

She also provided something the ex-patient community had lacked: an aspirational model. Her life had clearly flourished after quitting her medications. In 2019 she married Mr. Davis, an activist she met in the ex-patient movement; they are raising two boys in an airy, sun-drenched colonial-style house.

On the Surviving Antidepressants website, users sometimes invoked her name wistfully.

“I thought I’d be like a Laura Delano and others and heal right away,” a user from Kansas commented.

A French user, struggling to wean off Valium, returned to Ms. Delano’s videos as to a mantra.

“9.30 am: I manage to stop a panic attack with agitation, by breathing.

10:30 a.m.: It rains. I spend time on my smartphone. Laura Delano. Laura Delano. Laura Delano. On a loop. Maybe I’m in love.”

Emails began to flow in to Ms. Delano as she blogged about quitting her medications. Most were from people who wanted her advice on tapering. Often, she said, they had tried to taper too fast and were spinning out.

She encouraged them, assuring “overwhelmed, exhausted partners and parents” that what they were witnessing was not relapse, but withdrawal. Ms. Delano found that she was spending 25 hours a week on these calls. And a coaching business was born.

“I saw the demand for what I had to offer and made the difficult decision to stop giving my time away for free,” she writes in her memoir.

The market for assisting withdrawal from psychiatric medications is becoming crowded these days, with some private clinics charging thousands of dollars a week. And a watershed moment arrived last month, when Health Secretary Robert F. Kennedy Jr. announced that the new “Make America Healthy Again” commission would examine the “threat” posed by antidepressants and stimulants.

Mr. Kennedy has long expressed skepticism about psychiatric medications; in his confirmation hearings, he suggested that selective serotonin reuptake inhibitors, or S.S.R.I.s, have contributed to a rise in school shootings, and that they can be harder to quit than heroin. There is no evidence to back up either of these statements. But Mr. Davis agreed.

“He might be the only person in the room who gets how serious it can be,” Mr. Davis wrote on X during the hearings.

Ms. Delano and Mr. Davis both offer coaching — for $595 a month, you can join a group support program. But the project that excites them more is the membership community hosted by their nonprofit, Inner Compass Initiative, which, for $30 a month, links up members via livestreams, Zoom gatherings and a private social network.

They dream of a national “de-prescribing” network along the lines of Alcoholics Anonymous, said Mr. Davis, who became the group’s executive director early this year. “We know there is a sea change coming,” he said. “It’s already beginning. In a lot of circles, it’s deeply unfashionable to take psych meds.”

Ms. Delano has tempered her language since her Mad in America Days, when she protested outside annual meetings of the American Psychiatric Association, denouncing the use of four-point restraints and electroshock machines.

In the early pages of her memoir, she assures readers that she is not “anti-medication” or “anti-psychiatry.”

“To be clear, I am neither of these things,” she writes. “I know that many people feel helped by psychiatric drugs, especially when they’re used in the short term.”

Still, there is no mistaking the bedrock of mistrust that underlies her project. “I feel for psychiatry,” she said. “It’s a big ask we’re putting on them, to basically step back and consider that their entire paradigm of care is inadvertently causing harm to a lot of people.”

Earlier this month, Mr. Davis flew to Washington to hand-deliver copies of “Unshrunk” to elected officials and explore whether Inner Compass might find new sources of funding in the new, pharma-skeptical dispensation. He wanted to make sure, he said, “that the people working on policy are at least considering our ideas.”

The rollout of Mr. Kennedy’s agenda has raised hopes throughout “critical psychiatry” and “anti-psychiatry” communities that their critiques will, for the first time, be taken seriously.

Some in the medical world fear this augurs a deepening mistrust in science. And it is true — the written resources Inner Compass provides are overwhelmingly negative about every major class of psychiatric medications, which remain the only evidence-based treatment for severe mental illnesses.

A section on antipsychotics, for instance, cites studies that purport to show that people who take them fare worse than people who never take them or stop them. (This is misleading; people do not take them unless they have severe symptoms.) A section on antidepressants cites a study suggesting that they cause people to commit acts of violence. (The study was criticized for distorting its findings.)

Dr. Alpert, who is also chairman of psychiatry and behavioral sciences at Montefiore Einstein, reviewed Inner Compass’s resources and described them as “biased” and “frightening.” He said online peer communities risk becoming “echo chambers,” since they tend to attract people who have had bad experiences with medical treatment.

Because quitting psychiatric medications can be so risky, he said, a pervasive mistrust of medical care could have serious consequences.

“I mean, what happens when people taper their medications because of an echo chamber, and they’re more suicidal, or they get more psychotic, and they need to be hospitalized, or they lose their job?” he said. “Who cares about those people?”

This worry was shared even by some of Ms. Delano’s admirers in the world of patient advocacy. Mr. Whitaker recalled acquaintances who, after setting out to quit their medications, fell into “despair.”

“Once you start going down that road, it becomes your identity,” said Mr. Whitaker. “People want to come off, and the next thing you know, there’s no service provider, no science, and they’re moving into that void.”

Numerous people in withdrawal communities described members who struggled with suicidal thinking, or who had died by suicide.

“More often than not, at least from what I’ve seen, once people conclude that the medications hurt them, then it’s all-or-nothing, black-and-white thinking,” said Kate Speer, a strategist for the Harvard T.H.Chan School of Public Health’s Center for Health Communication “They can’t recognize the providers are there to help, even when what they have done is not helpful.”

Ms. Delano said the issue of suicide comes up regularly in withdrawal communities. “I know so many people who have killed themselves over the years, in withdrawal or even beyond” she said. In 2023, a young woman who joined Inner Compass died by suicide, she said.

Afterward, Ms. Delano and Mr. Davis consoled distraught community members, who worried that they should have taken some action to intervene.

Ms. Delano said she would call 911 if a member overdosed on pills, but, short of that, she doesn’t weigh in on treatment choices. She noted that many members come to withdrawal groups precisely because they feel they have been harmed by the medical system.

“We have given psychiatry and licensed mental health professionals this godlike power to keep people alive,” she said. “Speaking for myself — this is not an organizational belief, but for me personally — I don’t think anyone should have that power over another human being.”

In Inner Compass gatherings, many people describe tapering processes as so difficult that they had to stop and reinstate medications. Some were on their fifth or sixth attempt, and some wept, describing how challenging it was.

Ms. Delano tries to keep the pressure off. “You’re in the driver’s seat,” she told one coaching client, who had reinstated a low dose of Valium. “It doesn’t mean, quote unquote, giving up or losing or failing.”

Daniel seemed to be looking for some inspiration to stick it out. He was getting better, he was sure of it, accessing levels of emotion that had been blunted by medication for 15 years.

He credited Ms. Delano for getting him this far; it was reading her story in the New Yorker that made him see it was possible to “come off the medications and be OK.” On a recent Zoom session, he showed her the Post-it note that he sometimes pulls out as a reminder to himself.

“IT WAS THE DRUGS,” he had written

“It was the drugs!” Ms. Delano exclaimed. She welled up toward the end of their session, reflecting on how much he had already achieved.

“The trade-off is worth it,” she told him. “The more your life expands — the meaning, the connection, the beauty, the possibility, the more that continues to expand in your life, the more all these beautiful things come online, the less weight, the less power the hard stuff has.”

When they hung up, he was feeling certain of his path again.

She has this effect on him, making him imagine how he will feel when he is off medication — “this better, more complete me,” as he put it. He thinks it will take two or three years to taper off completely.

If it proves too difficult, “I just have to take 450 milligrams and consider myself lucky,” he said. “But there is a desire to, you know, just kind of be free. Free of it.”

California sees the most measles cases in 7 years as disease resurges nationwide

California sees the most measles cases in 7 years as disease resurges nationwide

California in 2026 has already seen its highest number of annual measles cases in seven years, health officials said, amid an ongoing resurgence of a notoriously infectious disease once considered effectively eliminated in the United States.

The looming new domestic beachhead for the disease comes as vaccination rates have tumbled nationwide in recent years — in some areas falling well below the herd immunity threshold experts say is necessary to keep it from spreading.

“There are pockets of vulnerability, like in communities, that can really lead to outbreaks going wild,” said Dr. Peter Chin-Hong, a UC San Francisco infectious diseases expert.

So far this year, there have been at least 40 confirmed measles cases in California. That’s well above the 25 recorded in all of 2025, according to Dr. Eric Sergienko, chief of the state Department of Public Health’s communicable disease control division. It’s also already the state’s highest single-year tally since 2019, when there were 73.

The latest measles case was announced Wednesday: an infant from San Francisco who was too young to be vaccinated and picked up the virus during an international trip. It was San Francisco’s first measles case since 2019. (The infant’s family was all vaccinated.)

The spread of the highly infectious virus is largely occurring among unvaccinated individuals, particularly children and younger adults, state health data show. Of the first 39 measles cases reported this year in California, 95% were among people who were unvaccinated or had an unknown immunization status, and 85% were in individuals under age 20, Sergienko said in a briefing to health professionals this week.

The measles vaccine — usually referred to as MMR, as it also conveys protection against two other once-common childhood illnesses, mumps and rubella — is considered to be 97% effective at preventing illness after getting the recommended two doses, and 93% effective after a single shot. There is a small chance that vaccinated people can still get measles, though they tend to have milder illness, according to the U.S. Centers for Disease Control and Prevention.

It was only a generation ago, in 2000, when the U.S. declared that ongoing transmission of measles had been eliminated — a public health success credited to a robust immunization effort following the disease’s resurgence from 1989 to 1991.

But some experts now fear the U.S. is in danger of allowing the virus to regain a foothold. Nationwide, there have been at least 1,714 confirmed measles cases so far this year, nearing the total of 2,287 reported in all of 2025, according to the CDC.

The number of cases recorded in 2025 was the highest single-year tally since 1991. An overwhelming majority of them, 90%, were linked to an outbreak.

Out of every 10,000 people who get measles, 500 children are statistically likely to get pneumonia, and up to 30 of them could die, Sergienko said.

Three measles deaths were reported nationally last year — two among unvaccinated school-age children in Texas and one in an unvaccinated adult in New Mexico.

Los Angeles County in September reported the death of a school-age child from a complication of measles. The child had been infected as an infant when they were too young to be vaccinated, and years later developed subacute sclerosing panencephalitis, or SSPE, a fatal disease that targets the brain.

Children typically receive their first MMR dose when they are 12 to 15 months old and the second when they are 4 to 6 years old, according to the CDC.

Babies age 6 months to 11 months and traveling internationally should get a dose, but should still get the standard two-dose series after their first birthday, the CDC says.

There have been three outbreaks fueling the spread of measles in California so far this year: one in Riverside County, involving three people infected in a single family; one in Shasta County, infecting nine people among a church group; and an ongoing outbreak in Sacramento County and neighboring Placer County, Sergienko said.

The outbreak in the Sacramento Valley was first identified in February, when officials reported that an unvaccinated toddler contracted measles after returning from South Carolina — where an outbreak centered in Spartanburg County has been linked to about 1,000 cases, health officials said. It is considered one of the largest outbreaks in the U.S. in more than 30 years.

Measles was then found in three siblings from a different household in Placer County who had contact with the traveling toddler.

Then, in early March, another measles case was identified in a child from the same community who attended what authorities described as an educational enrichment program, potentially exposing as many as 130 children to the virus, California health officials said. The organizers of the educational program agreed to close their facility temporarily.

L.A. County has reported four measles cases this year so far — all among those who recently traveled internationally. The most recent case involved someone aboard a Singapore Airlines flight that landed at Los Angeles International Airport on Feb. 9.

Orange County has reported a measles case in a young adult who potentially exposed people at a gym and urgent care center in Ladera Ranch, as well as a case in a toddler. They also reported two measles cases among travelers to Disneyland, one on Jan. 22 and the other on Jan. 28.

San Bernardino County reported a measles case in an unvaccinated child traveling from another state. San Diego County said an unvaccinated traveler who lives out of state potentially exposed people while visiting the emergency room of a local hospital in mid-March.

In the Bay Area, health officials reported a case of measles in a vaccinated Santa Clara County resident who recently returned from international travel, and potentially exposed people at a restaurant in Burlingame on Feb. 23 and Feb. 24.

Measles is one of the most contagious viruses known to humans. It can spread through coughing and sneezing, and remain infectious in the air up to two hours after an infected person has left a room. If infected, an individual will typically begin to show measles symptoms seven to 21 days after exposure.

Officials expect the Sacramento Valley measles outbreak to continue for at least the next few weeks.

“With four new cases coming up over the last week, we anticipate that this outbreak will be going on for at least another incubation period, for 21 days or so, as we look at potentially some undocumented transmission occurring within the impacted community,” Sergienko said Tuesday.

Nationally, measles vaccination rates among kindergartners have been declining. During the 2019-20 school year, 95.2% of children that age were fully vaccinated, but that slipped to 92.5% for the 2024-25 school year — below the herd-immunity target of 95%, according to the CDC.

The measles vaccination rate for California kindergartners was 96.1% in 2024-25, among the highest in the nation. Some of the states that have undergone big breakouts have rates for kindergartners below the 95% goal — Texas was 93.2%; New Mexico, 94.8%; and South Carolina, 91.2%.

California has sweeping vaccination requirements as a condition of enrollment in public and private schools, as well as daycare centers, with exceptions only for medical reasons. Parents who opt not to vaccinate due to their beliefs can homeschool their children and enroll them in independent study, provided they do not “receive classroom-based instruction.”

But, as a Times story last year noted, California’s laws don’t define what “classroom-based instruction” means, including whether students need to be vaccinated if they attend some in-person classes or school-sanctioned activities like field trips, soccer practice or prom. Opponents of school vaccination requirements are also working to pressure states like California to weaken them.

Anti-vaccine advocates have been emboldened in recent years with the rise of Health and Human Services Secretary Robert F. Kennedy Jr., a longtime vaccine skeptic.

In March 2025, Kennedy issued a statement that noted vaccines’ effectiveness in preventing measles’ spread, but stopped short of outright recommending that parents vaccinate their children.

Yet as the year went on, Kennedy and the agencies he leads upended the nation’s vaccine delivery system, while publicly sharing misleading and inaccurate information about immunizations.

As recent outbreaks show, measles can spread quickly if it gets into pockets of unimmunized communities, and babies too young to be vaccinated can be at risk for serious illness and death.

One such example was the Disneyland measles outbreak of December 2014 to April 2015, which resulted in 131 cases among Californians, and spread to people in six other states, as well as Canada and Mexico. Among the measles cases in California, at least 12 of those infected were infants too young to be vaccinated.

Measles symptoms don’t usually start with the telltale rash, Sergienko said. The disease begins with a mild-to-moderate fever, then a cough, runny nose and red, watery eyes. It takes two or three days later before tiny white lesions, known as Koplik spots, appear inside the mouth, and an additional fever may spike, with temperatures that can exceed 104 degrees.

A couple of days later, the red measles rash emerges, starting at the hairline and moving downward, Sergienko said.

Officials urge people who suspect they or their child have measles call their healthcare provider. Healthcare providers are advised to evaluate a suspected measles patient in a way that doesn’t expose other patients to the virus.

Health officials urged people to get up to date on the measles vaccine if they haven’t done so.

“We all need to work together to share the medical evidence, benefits, and safety of vaccines to provide families the information they need to protect children and our communities,” Dr. Erica Pan, director of the California Department of Public Health, said.

A cracked heat shield rattled NASA after Artemis I. Now, Artemis II will put the fix to the test

A cracked heat shield rattled NASA after Artemis I. Now, Artemis II will put the fix to the test

The Artemis II astronauts are scheduled to return Friday from their trip to the moon. When they do, they will slam into Earth’s atmosphere at over 32 times the speed of sound — and will do so using a reentry technique that has yet to be tested in real-world scenarios.

In 2022, NASA sent the uncrewed Artemis I test mission to the moon. As it pierced through the Earth’s atmosphere on return, the capsule suffered unexpected damage to its heat shield, prompting NASA scientists to rethink what’s needed to keep the homeward-bound Artemis II astronauts safe.

There’s been a ton of work done to prepare for this moment — but the reality is, scientists won’t know exactly how the heat shield will behave until they test it in a bona fide reentry.

That’s why a team of NASA and Department of Defense scientists and test pilots stand at the ready to collect detailed data on how the heat shield performs as the capsule streaks through the sky, turning the atmosphere around it into a bright fireball about half as hot as the surface of the sun before splashing down off the coast of San Diego.

Test pilots stationed at Southern California military bases will take turns chasing the capsule in a complex, high-speed relay: first a NASA business jet, then a Navy surveillance aircraft, followed by another NASA jet, and finally a NASA weather research aircraft. Crews on the ground will monitor the Artemis II capsule and send those test pilots precise speeds and coordinates to hit as they follow the fireball in the sky. Meanwhile, researchers in the back of the planes will track the capsule with telescopes and sensors.

“It’s an exciting job threading the needle multiple times,” said Robert Navarro, project manager at NASA’s Armstrong Flight Research Center in Edwards, Calif., which is in charge of the critical third segment of the relay. “It has to be precise, simply because of the short window of time that they need to collect that data. They have to be exactly right on the mark.”

After splashdown, a separate Armstrong Flight Research Center team will collect a fortified sensor affixed to the exterior of the capsule that is designed to study the heat shield up close.

“I’m really excited that my team is a part of such an important mission,” said Patty Ortiz, deputy project manager for the capsule sensor project at the center. “Having worked on it since 2019, it’s definitely a full-circle moment for me.”

The center has pushed the limits of human flight for decades — and collected a lot of data doing so.

“We consider our airplanes flying labs — we’re going to go do things that maybe haven’t been done before,” said Brad Flick, who retired as director of the center March 20 after nearly four decades at the research facility.

In the 1960s, engineers at the Flight Research Center helped design and test a mock-up of the Apollo lunar landing vehicle that Neil Armstrong used for landing practice on Earth before he flew to the moon. (The center was later renamed after him, the first person to walk on the lunar surface.)

The center has been preparing to study the Artemis II reentry for years, but the work became even more important after NASA discovered issues with the heat shield after the Artemis I test mission.

NASA guided the Artemis I capsule to first only graze the Earth’s atmosphere before briefly popping back up into space, then completing the final reentry. This novel approach reduced the forces that astronauts would experience on reentry and helped NASA to more precisely maneuver the capsule to its landing point in the Pacific — regardless of where or when it comes back from the moon.

That mission seemed like a success, but when crews began inspecting the heat shield on the bottom of the uncrewed capsule after splashdown, they noticed a problem.

After NASA’s Orion spacecraft was recovered at the conclusion of the Artemis I test flight and transported to NASA’s Kennedy Space Center in Florida, its heat shield was removed from the crew module inside the Operations and Checkout Building and rotated for inspection.

The heat shield is designed to slowly erode (or “ablate,” in NASA parlance) away during reentry to keep conditions in the capsule livable while the air a few inches away can reach nearly 5,000 degrees Fahrenheit: The outside layer of the shield routinely heats up, then sloughs off in the form of gas and pieces of char, which carry that heat away from the capsule as they disperse into the atmosphere around the capsule.

The problem with Artemis I was that the new reentry approach NASA had attempted seemed to disrupt this ablation process.

Because Artemis I went back into space between the first dip into the atmosphere and the final reentry, there was a brief respite in its heat exposure — that meant that the hot interior of the heat shield kept producing gases, but the exterior was no longer shedding material fast enough to allow those gases to escape. Pressure built up, which cracked the heat shield and ultimately resulted in larger pieces chipping off during the final reentry.

NASA scientists determined that had a crew been onboard, they would have survived — but they didn’t want to expose the Artemis II astronauts to unnecessary risk.

That left two options: First, replace the already-built Artemis II heat shield with a new design in the works that could handle the reentry path attempted with Artemis I. Second, change the reentry path to skip the first dip into the atmosphere and just go straight in to eliminate the conditions that created the problem in the first place.

The agency ultimately deemed replacing the Artemis II heat shield too much of a logistical headache and opted for the latter, simpler approach. On Friday, NASA astronauts will put that decision to the test. Armstrong Flight Research Center scientists are standing by to watch.

Near the shrinking Salton Sea, children’s lungs may pay a price

Along the shores of the shrinking Salton Sea, desert winds regularly kick up dust and send it drifting through nearby neighborhoods. New research indicates that living there may affect kids’ lungs.

Scientists from the University of Southern California tested the lung capacity of 369 children between the ages of 10 and 12 for about two years and found that those who live less than 6.8 miles from the Salton Sea have diminished lung development compared with kids farther away.

The slower pulmonary development in these children was similar to the development of those who live very close to freeways.

“Basically, their overall lung capacity isn’t developing at the same rate as kids that live further away,” said Shohreh Farzan, a co-author of the study and associate professor at the USC Keck School of Medicine. “We’re seeing the impacts of dust events and proximity to the sea as being detrimental to children’s lung development.”

When lung growth is hindered in adolescence, “that can lead to increased risk for respiratory, cardiovascular, and metabolic diseases later in life,” said Fangqi Guo, the study’s lead author.

The Salton Sea is California’s largest lake, covering about 300 square miles in Imperial and Riverside counties. It’s fed as Colorado River water drains off farm fields in the Imperial Valley.

The saline lake has been shrinking rapidly since the early 2000s, when the Imperial Irrigation District began selling some of its Colorado River water to growing urban areas under an agreement with agencies in San Diego County and the Coachella Valley.

The lake has gone down 14.5 feet since 2003, exposing more than 41,000 acres of lakebed. Researchers say years of agricultural chemicals and metals washing into the lake have made the dust toxic.

In low-income communities near the lake, children suffer from asthma at high rates. Researchers have previously found that about 1 in 5 children in the area have asthma, nearly triple the national average.

Other research has shown that dust collected near the Salton Sea triggers lung inflammation in mice.

For the latest study, published in JAMA Network Open, the USC researchers worked with the community group Comité Civico del Valle to recruit children to participate.

They measured how much air the children can push out after a deep breath.

They examined levels of fine particles in the air, as well as times when dust levels spike, often triggered by winds.

Dust around the Salton Sea has been recognized as a health problem for years.

To help control it and provide habitat for fish and birds, California agencies have been building berms and sending water flowing into man-made ponds along the shore, creating new wetlands. They’ve also been placing thousands of bales of straw on the exposed lakebed to block windblown dust.

“I think these efforts are not moving quickly enough,” Farzan said. “We need to have a renewed focus on making sure that we’re protecting children’s health.”

The dust doesn’t come only from the Salton Sea playa. It comes from the surrounding landscape, including farm fields, livestock operations, diesel exhaust and unpaved roads.

In a report last year, researchers with the Pacific Institute cited estimates that dust from the Salton Sea accounts for less than 1% of small particle pollution in the region.

Even though it may be a small percentage, Farzan said, “our results are clearly showing that there is something about proximity to the sea that is impactful for children’s health.”

The researchers did not differentiate between sources of dust in their latest study.

“It is possible that that small fraction may be more toxic, may contain different contaminants,” she said. “That’s something that we’re still really interested in learning more about.”

The dust could worsen if looming water cutbacks on the Colorado River accelerate the decline of the Salton Sea. The river flow has declined dramatically over the last quarter-century during a megadrought worsened by climate change.

There are similar issues at other drying lakes around the world, from Utah’s Great Salt Lake to the Aral Sea in Central Asia, Farzan noted, and this will require bigger efforts to contend with dust and its effects on people’s health.
