An Uncontrolled Chinese Rocket Body Is Returning From Space. Where Will It Land?

Building of China’s Tiangong house station continued easily this week with the launch and docking of Wentian, a laboratory module. The set up of the lab advances the progress of a second outpost in orbit the place humanity is ready to conduct scientific analysis in a microgravity surroundings.

China plans to function the brand new Tiangong station for not less than a decade, inviting different nations to participate. Tiangong is smaller than the growing old Worldwide House Station, which is to be retired in 2030 beneath NASA’s present plans, though Russia has given conflicting indicators of how lengthy it would proceed to take part.

However as with two earlier house missions by China, Sunday’s launch resulted in a 23-ton booster stage from the Lengthy March 5B rocket orbiting the planet. The booster, a part of China’s strongest rocket, is predicted to fall again to Earth in the course of the coming day, and nobody is aware of precisely the place it would land.

China’s lack of any method to information the booster down leaves the uncomfortable risk that particles might descend in a populated space, inflicting property harm, harm and even dying on the bottom.

As of Friday afternoon, the Aerospace Company, a nonprofit group that performs analysis and evaluation together with the monitoring of house particles, is predicting re-entry on Saturday at 2:16 p.m. Japanese time over the Indian Ocean.

However the uncertainty remains to be vital — give or take 5 hours — and since the booster takes only one.5 hours to circle all the best way world wide, the re-entry level might nonetheless happen over a lot of the planet.

Whereas China’s house companies are offering public information on the orbital path of the rocket physique, they don’t seem to be predicting the place or when it would re-enter. They didn’t reply to requests for remark earlier than Saturday.

Should you’re in Chicago or wherever else above 41.5 levels north latitude or in Antarctica or the southern tip of South America under 41.5 levels south latitude, you’re completely protected.

The trajectories on Saturday in the course of the interval when the booster is predicted to re-enter additionally don’t cross over Europe or a lot of northern Africa.

Even should you stay someplace the place the rocket will cross over, you may have a greater probability at successful the Mega Thousands and thousands lottery than getting hit by a falling piece of rocket particles.

However the cumulative threat of somebody being injured is greater than specialists would really like. (Somebody will win the Mega Thousands and thousands; it nearly definitely received’t be you.)

“This can be a actual concern,” mentioned Ted Muelhaupt, an area particles knowledgeable on the Aerospace Company. “The Chinese language shouldn’t do that.”

However he added, “It isn’t a trigger for panic. No one must be strolling round with soccer helmets on simply in case of falling house particles.”

Precisely how a lot threat the booster poses is troublesome to estimate as a result of the main points of the rocket’s design affect how a lot particles survives re-entry and reaches the bottom.

House companies in China haven’t supplied these particulars or launched their estimates of the danger. However they may have determined this was an appropriate threat, betting that the hazard for a small variety of launches just isn’t excessive sufficient to justify the prices of adjusting how the rocket operates.

To this point, there have been two different Lengthy March 5B launches. The primary booster fell on villages in Ivory Coast in western Africa, inflicting some property harm however no accidents. The second booster splashed within the Indian Ocean.

When NASA’s Higher Ambiance Analysis Satellite tv for pc, which was the scale of a metropolis bus, made an uncontrolled re-entry in 2011, NASA calculated a 1-in-3,200 probability that somebody might be injured. It ended up falling within the Pacific Ocean.

Usually 20 p.c to 40 p.c of a rocket or satellite tv for pc survive re-entry, Mr. Muelhaupt mentioned, which might counsel that 10,000 to twenty,000 kilos of the Chinese language booster would attain Earth’s floor.

For essentially the most half, organizations launching giant rockets and satellites as of late take precautions to be sure that their house particles doesn’t fall over populated areas. Typically, it nonetheless happens, as in 2021 when a malfunction on the second stage of a SpaceX Falcon 9 rocket prevented its engines from directing it to a protected re-entry. Particles fell on a farm in central Washington. There have been no accidents from that incident; the four-ton Falcon 9 second stage is significantly smaller than the 23-ton Lengthy March 5B booster.

In 2003, when the house shuttle Columbia disintegrated because it re-entered the ambiance, particles scattered throughout japanese Texas and southern Louisiana. Almost 85,000 kilos of particles from Columbia had been recovered; not one of the items induced any accidents.

The Lengthy March 5B is exclusive for contemporary rocketry in that China has not put any effort to controlling the re-entry of one thing so large.

Most large rockets have two or extra levels. The primary stage, the largest piece of the rocket, sometimes drops off a couple of minutes after launch with out ever reaching orbit. That method, there isn’t a shock the place it will come down. (One cause the Kennedy House Heart is in Florida is the situation close to the Atlantic Ocean, the place the primary levels of rockets fall.)

The Lengthy March 5B, which was designed to elevate the Tiangong modules, is totally different. Chinese language officers have referred to the booster because the second stage, making an attempt to attract parallels to the Falcon 9 second stage that fell over Washington State. However the Lengthy March 5B has no second stage. The large central booster that ignites at liftoff accompanies the payload all the best way to orbit, and the Chinese language didn’t design any method to convey the booster again down from orbit. (4 strap-on boosters do drop off harmlessly in the course of the launch.)

The booster’s engines aren’t designed to restart, so these can’t be used to information the booster again into the ambiance. The rocket’s designers might have included thrusters for that job, however they might have added weight and complexity.

On Wednesday, Zhao Lijian, spokesman of China’s Ministry of Overseas Affairs, mentioned that the Lengthy March 5B rocket is designed with particular know-how, though he didn’t specify what sort. The overwhelming majority of its elements would fritter away in the course of the re-entry into the ambiance, he added.

“The chance of this course of inflicting hurt to aviation actions or to the bottom is extraordinarily low,” he mentioned.

Pressure is mounting for soil testing post-fire cleanup. The Newsom administration is downplaying the concerns

Pressure is mounting for soil testing post-fire cleanup. The Newsom administration is downplaying the concerns

Elected officials in California are calling on the Federal Emergency Management Agency and the Newsom administration to pay for soil testing on properties destroyed in the Eaton and Palisades wildfires, underscoring the public health risk and financial burdens that could be faced by survivors seeking to rebuild in Altadena and Pacific Palisades.

FEMA, the agency leading the wildfire recovery efforts, has come under heavy criticism for its decision not to test properties for contaminants after removing wreckage and up to 6 inches of top soil. That policy differs from how California has handled virtually all wildfire recoveries in the recent past.

After every major wildfire since 2007, federal and state disaster agencies have conducted soil sampling to ensure that debris-cleared properties do not contain unhealthy levels of lead and other toxic metals. In these cases, at properties where agencies detected high levels of contaminants, they typically deployed cleanup crews to remove another layer of soil, and then would perform another round of soil testing. This would be repeated until testing showed that the soil met state standards.

Following the 2025 L.A. wildfires, however, FEMA has repeatedly refused to pay for soil testing, contending that removing wildfire debris and up to 6 inches of topsoil from portions of destroyed homes is sufficient to eliminate any immediate health threats.

This month, U.S. Rep. Judy Chu (D-Pasadena) led a contingent of 28 federal legislators in writing a letter demanding that FEMA reassess its decision. The letter, sent June 3, calls for federal funding for soil testing and for further remediation at properties with soil contamination above California’s standards.

In a separate letter, sent Thursday, state Sen. Ben Allen (D-Santa Barbara) and three other state legislators urged California environmental regulators to step in and conduct soil sampling if federal disaster agencies continue to resist soil testing protocols. The letter recommends that state officials tap a $2.5-billion emergency relief package signed by Gov. Gavin Newsom in January, which includes funding for debris cleanup and post-fire assessments.

Allen’s letter said the state’s decision to leave burned-down homes untested “will reverse precedent and lower standards for future disasters.” Without comprehensive government-led soil testing, the letter argued, homeowners would be left to pay for soil sampling themselves or risk returning to a property with unsafe levels of contamination.

“It is deeply unjust that this responsibility has fallen to fire survivors — already burdened by the challenges of total loss recovery — simply because federal partners like FEMA and the U.S. Army Corps of Engineers have failed to lead,” write Allen and his co-signatories in the letter. “The State of California now has the opportunity to fill that gap with leadership that centers science, transparency, and community needs.”

In February, the Newsom administration asked FEMA to reconsider its decision not to conduct post-cleanup soil testing, stressing that fire-related contamination can remain undetected and pose public health risks, even after cleanup crews finish their first pass at a property. But federal officials swiftly rejected the request, and instead suggested that state and local officials should perform this work.

Since then, the pressure has continued for California officials to step up.

Last month, a coalition of environmental researchers wrote a letter to the Newsom administration, urging state agencies pay for soil testing.

The Newsom administration appears to be walking back its concerns about lingering fire-related contamination. In a June 6 letter replying to those researchers, CalEPA Secretary Yana Garcia downplayed the risks of lingering contamination from the Eaton and Palisades wildfires.

Although air quality and soil testing have found high levels of lead downwind of the Eaton fire, Garcia said that some of this soil contamination could have resulted from the historical use of leaded gasoline in cars and heavy industry.

“It is in this environment, not a clean slate, that the Palisades and Eaton Fires occurred,” she wrote in her letter.

Soil testing carried out by Los Angeles Times journalists in March provided the first evidence that homes cleaned by federal cleanup crews still contained elevated levels of lead and arsenic. Soon after, the Los Angeles County Department of Public Health also published preliminary data finding 27% of soil samples collected at already-cleaned homes still had lead above state standards for residential properties.

Despite these soil sampling results, Garcia signaled she is satisfied with the federal cleanup.

“Sampling results so far are demonstrating the effectiveness of the existing clean-up approach,” Garcia wrote in the letter.

(The health department denied an L.A. Times public records request seeking the raw data showing the extent of the soil contamination detected, saying the results had yet to be finalized. The department also declined requests for a copy of its contract with Roux Associates, including how much the county had paid the consultant to perform the soil sampling.)

Garcia stressed that blood testing around the wildfire-affected communities showed overall exposure was low. She did not directly respond to the researchers’ request to pay for soil testing for the L.A. wildfires.

Sen. Allen and the three state legislators who cosigned his public letter are seeking more answers from state environmental agencies. The letter calls for state environmental agencies to convene a public meeting by the end of June to discuss post-wildfire soil testing protocols and plans for the L.A. wildfires.

CalEPA officials did not immediately respond to a request for comment.

Former Cedars-Sinai OB-GYN surrenders license after sexual abuse complaints

Former Cedars-Sinai OB-GYN surrenders license after sexual abuse complaints

Former Cedars-Sinai Medical Center obstetrician-gynecologist Barry J. Brock has surrendered his medical license following an accusation of negligent care from the state medical board.

Brock, 75, signed an agreement late last month to give up the license he has held since 1978, rather than contest an accusation the Medical Board of California filed in September regarding a former patient’s treatment. The surrender took effect on Wednesday.

While Brock “doesn’t admit any factual allegations,” his attorney Tracy Green said, he elected to surrender his license rather than invest time and money into a hearing.

Under the terms of the agreement, Brock is barred from legally practicing medicine in California for the rest of his life.

Brock retired from medicine in August. Since then, at least 176 women have filed lawsuits alleging that Cedars-Sinai and other facilities where Brock worked knowingly concealed his sexual abuses and misconduct, including medically unjustifiable procedures that at times resulted in lasting physical complications.

Brock has denied all allegations of impropriety. The OB-GYN was a member of the Cedars-Sinai physician network until 2018 and retained his clinical privileges there until mid-2024.

Cedars-Sinai confirmed in July that it suspended Brock’s hospital privileges after receiving “concerning complaints” from former patients. His privileges were terminated a few months later.

“The type of behavior alleged about Dr. Barry Brock is counter to Cedars-Sinai’s core values and the trust we strive to earn every day with our patients,” the medical center said in a statement. “We recognize the legal process must now take its course, and we remain committed to Cedars-Sinai’s sacred healing mission.”

The accusation that led to the surrender of his license focused on a patient who sought treatment in 2018 for a blighted ovum, a form of miscarriage in which the fertilized egg fails to develop into an embryo.

According to the complaint, the patient reported to Brock’s office in September 2018 for a dilation and curettage to remove remaining tissues from her uterus.

Brock ordered the patient to undress in front of him, the complaint stated, and didn’t wear gloves during the procedure, which was done without a chaperone present.

The patient experienced severe pain during the visit and bled for two months afterward, the complaint said, and no follow-up care was provided. When she visited a physician’s assistant in November 2018, the complaint said, she learned that Brock had failed to complete the dilation and curettage successfully, and she had to undergo the process a second time to remove the remaining tissue.

The complaint alleged that Brock didn’t administer sufficient pain medication and failed to properly complete the procedure or follow up with pathology findings.

While Brock’s license surrender resolves this accusation, he still faces the civil lawsuits.

Suits were filed on behalf of 167 women last year, and nine more women sued the former physician earlier this month, alleging that Brock groped their breasts and genitals inappropriately during appointments, often with bare hands, and made sexually harassing comments.

“This is why these civil lawsuits and these women coming forward … are so, so important. He can’t avoid this,” said Lisa Esser, an attorney representing the nine plaintiffs. “He’s going to be held accountable.”

State rescinds suspension efforts for troubled nursing home in Hollywood

State rescinds suspension efforts for troubled nursing home in Hollywood

The California Public Health Department has dropped efforts to suspend the license of a Hollywood nursing home whose actions were found to have led to two patient deaths in recent years.

Brier Oak on Sunset was among seven Los Angeles County facilities that received notice last month that the state was moving to suspend their licenses.

At the time, the state believed all seven companies had received at least two “AA” violations within the last two years, a spokesperson for the Public Health Department said.

An AA violation is a relatively rare penalty issued for errors that contribute substantially to a resident’s death. California law allows the suspension or revocation of a nursing home’s license once a facility gets two such violations within a 24-month period.

Although Brier Oak received its AA violation notices 22 months apart, the residents’ deaths took place about 26 months apart, state records show.

“We recently determined that Brier Oak’s Notice was based on citation issuance date, not the date of the incidents that gave rise to the citations,” the health department said in a statement. “Therefore, this Notice of Suspension has been rescinded.”

Brier Oak on Sunset didn’t immediately respond to a request for comment.

The state investigation found that staff oversights at Brier Oak led to the deaths of two residents in 2022 and 2024.

In August, a patient died after rolling off a bed while her nurse was tending to a different patient, the state said in its citation report, which noted that paramedics found the woman lying on the floor in a pool of blood.

In May 2022, a patient died roughly 50 hours after her admission to Brier Oak. An investigation determined that staff neglected to administer crucial medications, the state said.

In a September 2022 phone interview, the patient’s family member told state investigators that “Resident 1 ‘did not get her medications for two days [from admission] and staff let her die,’” the state wrote in its report. The family member continued: “She did not deserve to die.”

The patient’s family was awarded $1.29 million in arbitration this month after a judge found that the facility was severely understaffed at the time of her arrival and should not have admitted her.

“Respondent’s Facility acted with recklessness in that they knew it was highly probable that their conduct would cause harm, and they knowingly disregarded this risk,” Superior Court Judge Terry A. Green wrote in the interim arbitration award.

License suspension efforts are still proceeding against Antelope Valley Care Center in Lancaster, Ararat Nursing Facility in Mission Hills, Golden Haven Care Center in Glendale, Kei-Ai Los Angeles Healthcare Center in Lincoln Park, Santa Anita Convalescent Hospital in Temple City and Seacrest Post-Acute Care Center in San Pedro.

Attorneys for Ararat said that the suspension was “unwarranted” and that it will be appealing. The other facilities didn’t respond to requests for comment.
