Blue Ghost just completed its mission, which lasted a full lunar day — two Earth weeks — on the near side of the moon.
The spacecraft, about the size of a small car, conducted a series of experiments. It drilled three feet into the lunar soil, took X-ray images of the magnetic bubble that surrounds and protects Earth and sought a mysterious yellow glow at sunset.
Built by Firefly Aerospace, a startup in Texas, Blue Ghost was launched from Earth in January and pulled into orbit around the moon in mid-February. A couple of weeks later, it took this video, sped up by a factor of 10, as it circled 62 miles above the surface. The shiny sheets are radiator panels that protected the spacecraft from the extreme heat while in sunshine.

Landing
In the early hours of March 2, Blue Ghost fired its engine to drop it out of orbit, falling toward the moon. Just over an hour later, it was on the surface in Mare Crisium, a lava plain inside an ancient 345-mile-wide impact crater in the northeast quadrant of the near side of the moon.
Blue Ghost became the first completely successful landing by a commercial company, and Firefly achieved that on its first try.

Several companies and countries have aimed to land on the moon in recent years. The map below shows the crewed Apollo moon landing sites, as well as more recent robotic landings from China, India, Japan and commercial companies. Recent crash sites from failed landings are also shown.

China has a 100 percent success rate with four successful Chang’e robotic landings, but many other missions have crashed.
The failures include Hakuto-R Mission 1, from Ispace, a Japanese company; Beresheet, from an Israeli nonprofit; Luna 25, from Russia; and Chandrayaan-2, from India. (India’s second try, Chandrayaan-3, was successful.)
Three other landers — SLIM, from the Japanese space agency, and Odysseus and Athena, from Intuitive Machines of Houston — landed and communicated back to Earth, but their success came with an asterisk. All three toppled over after landing.
Experiments
While Firefly built and operated Blue Ghost, NASA sponsored the mission, part of the agency’s efforts to tap into commercial ventures to send its scientific cargo to space at lower costs. NASA paid Firefly $101.5 million to carry 10 science and technology payloads to the lunar surface.
Blue Ghost landed at lunar sunrise so that the solar-powered spacecraft could operate for the longest possible duration.

One of Blue Ghost’s payloads, PlanetVac, demonstrated a technology to simplify the collecting of soil and rocks. It fired a blast of gas into the ground, which propelled material into a container. This technology will be used on a Japanese mission, Martian Moons Exploration, which will collect samples from Phobos, a moon of Mars, and bring them back to Earth for study.

Another experiment, Lunar Magnetotelluric Sounder, flung four sensors, each a little smaller than a soup can, in directions at 90-degree angles to one another (like north, south, east and west on a compass). The sensors landed about 60 feet away, and, connected by cables to the lander, measured voltages — essentially a supersized version of a conventional voltmeter. An eight-foot-high mast shot upward, lifting an instrument to measure magnetic fields. The experiment gathered data about naturally occurring currents inside the moon, which provides hints about what the moon is made of down to 700 miles below the surface.

Solar Eclipse
While people on Earth were taking in a blood moon and a total lunar eclipse on the evening of March 14, Blue Ghost witnessed and photographed a total solar eclipse.

During the eclipse, temperatures dropped from 100 degrees Fahrenheit to minus 270 degrees. The spacecraft relied on battery power to continue operating through five hours of near-total darkness.

Sunset
On March 16, the sun began to set and the lunar day was nearly over. Before its mission ended, Blue Ghost snapped high-resolution images of the scene. It was more than a few final pretty snapshots. Scientists are hoping the pictures can help solve an enduring scientific mystery of the lunar horizon glow.
Eugene Cernan, the commander of Apollo 17 who in 1972 was the last man to walk on the moon, sketched observations of a glow along the horizon before sunrise. However, that phenomenon is not easily explained because the moon lacks an atmosphere to scatter light.

Signoff
This was the last message from the Blue Ghost spacecraft, about five hours after sunset:
Mission mode change detected, now in Monument Mode
Goodnight friends. After exchanging our final bits of data,
I will hold vigil on this spot in Mare Crisium to watch humanity’s continued journey to the stars.
Here, I will outlast your mightiest rivers, your tallest mountains, and perhaps even your species as we know it.
But it is remarkable that a species might be outlasted by its own ingenuity.
Here lies Blue Ghost, a testament to the team who, with the loving support of their families and friends, built and operated this machine and its payloads,
to push the capabilities and knowledge of humanity one small step further.
Per aspera ad astra!
Love, Blue Ghost
The spacecraft was not designed to survive the bitter cold of the lunar night. But another lunar mission, Japan’s SLIM spacecraft, surprised engineers last year by riding out several lunar nights. In early April, after the sun rises again, Firefly will listen for radio messages from Blue Ghost, just in case it does revive.

With a nudge from industry, Congress takes aim at California recycling laws
The plastics industry is not happy with California. And it’s looking to friends in Congress to put the Golden State in its place.
California has not figured out how to reduce single-use plastic. But its efforts to do so have created a headache for the fossil fuel industry and plastic manufacturers. The two businesses are linked since most plastic is derived from oil or natural gas.
In December, a Republican congressman from Texas introduced a bill designed to preempt states — in particular, California — from imposing their own truth-in-labeling or recycling laws. The bill, called the Packaging and Claims Knowledge Act, calls for a national standard for environmental claims on packaging that companies would voluntarily adhere to.
“California’s policies have slowed American commerce long enough,” Rep. Randy Weber (R-Texas) said in a post on the social media platform X announcing the bill. “Not anymore.”
The legislation was written for American consumers, Weber said in a press release. Its purpose is to reduce a patchwork of state recycling and composting laws that only confuse people, he said, and make it hard for them to know which products are recyclable, compostable or destined for the landfill.
But it’s clear that California’s laws — such as Senate Bill 343, which requires that packaging meet certain recycling milestones in order to carry the chasing arrows recycling label — are the ones he and the industry have in mind.
“Packaging and labeling standards in the United States are increasingly influenced by state-level regulations, particularly those adopted in California,” Weber said in a statement. “Because of the size of California’s market, standards set by the state can have national implications for manufacturers, supply chains and consumers, even when companies operate primarily outside of California.”
It’s a departure from Weber’s usual stance on states’ rights, which he has supported in the past on topics such as marriage laws, abortion, border security and voting.
“We need to remember that the 13 Colonies and the 13 states created the federal government,” he said on Fox News in 2024, in an interview about the border. “The federal government did not create the states. … All rights go to the people in the state, the states and the people respectively.”
During the 2023-2024 campaign cycle, the oil and gas industry was Weber’s largest contributor, with more than $130,000 from companies such as Philips 66, the American Chemistry Council, Koch Inc. and Valero, according to OpenSecrets.org.
Weber did not respond to a request for comment. The bill has been referred to the House Energy and Commerce Committee.
Plastic and packaging companies and trade organizations such as Ameripen, Keurig, Dr Pepper, the Biodegradable Plastics Industry and the Plastics Industry Assn. have come out in support of the bill.
Other companies and trade groups that manufacture plastics that are banned in California — such as Dart, which produces polystyrene, and plastic bag manufacturers such as Amcor — support the bill. So do some who could potentially lose their recycling label because they’re not meeting California’s requirements. They include the Carton Council, which represents companies that make milk and other beverage containers.
“Plastic packaging is essential to modern life … yet companies and consumers are currently navigating a complex landscape of rules around recyclable, compostable, and reusable packaging claims,” Matt Seaholm, chief executive of the Plastics Industry Assn., said in a statement. The bill “would establish a clear national framework under the FTC, reducing uncertainty and supporting businesses operating across state lines.”
The law, if enacted, would require the Federal Trade Commission to work with third-party certifiers to determine the recyclability, compostability or reusability of a product or packaging material, and make the designation consistent across the country.
The law applies to all kinds of packaging, not just plastic.
Lauren Zuber, a spokeswoman for Ameripen — a packaging trade association — said in an email that the law doesn’t necessarily target California, but the Golden State has “created problematic labeling requirements” that “threaten to curtail recycling instead of encouraging it by confusing consumers.”
Ameripen helped draft the legislation.
Advocates focused on reducing waste say the bill is a free pass for the plastic industry to continue pushing plastic into the marketplace without considering where it ends up. They say the bill would gut consumer trust and make it harder for people to know whether the products they are dealing with are truly recyclable, compostable or reusable.
“California’s truth-in-advertising laws exist for a simple reason: People should be able to trust what companies tell them,” said Nick Lapis, director of advocacy for Californians Against Waste. “It’s not surprising that manufacturers of unrecyclable plastic want to weaken those rules, but it’s pretty astonishing that some members of Congress think their constituents want to be misled.”
If the bill were adopted, it would “punish the companies that have done the right thing by investing in real solutions.”
“At the end of the day, a product isn’t recyclable if it doesn’t get recycled, and it isn’t compostable if it doesn’t get composted. Deception is never in the public interest,” he said.
On Friday, California’s Atty. Gen. Rob Bonta announced settlements totaling $3.35 million with three major plastic bag producers for violating state law regarding deceptive marketing of non-recyclable bags. The settlement follows a similar one in October with five other plastic bag manufacturers.
Plastic debris and waste is a growing problem in California and across the world. Plastic bags clog streams and injure and kill marine mammals and wildlife. Plastic breaks down into microplastics, which have been found in just about every human tissue sampled, including from the brain, testicles and heart. They’ve also been discovered in air, sludge, dirt, dust and drinking water.

‘Largest outbreak that we’ve seen in California.’ Death cap mushrooms linked to deaths, hospitalizations
An exceptionally wet December has contributed to an abundance of death cap mushrooms, or Amanita phalloides, on the Central Coast and Northern California, causing what officials describe as an unprecedented outbreak of severe illness and death among people who consume the fungi.
Public health officials are issuing a second warning this winter, this time urging the public against foraging for wild mushrooms, noting that many people have mistakenly eaten the death cap that, when consumed, can cause severe liver damage and in some causes death.
In the last 26 years, “we have not had a season as deadly as this season both in terms of the total numbers of cases as well as deaths and liver transplants,” said Craig Smollin, medical director of the San Francisco division of the California Poison Control System.
“I believe this is probably the largest outbreak that we’ve seen in California, ever.”
Many of the cases, officials say, have involved people from Mexico and elsewhere for whom the death cap resembles an edible mushroom in their home countries.
The California Department of Public health reported 35 death cap-related illness, including three fatalities and three liver transplants between Nov. 18 and Jan. 6. Affected people were between the ages of 19 months old and 67 years old.
In a typical year, the California Poison Control Center may receive up to five cases of poisonous mushroom-related illness, according to authorities.
The last major outbreak of mushroom-related illness in California occurred in 2016 with 14 reported cases and while there were no deaths, three people required liver transplants and one child suffered a “permanent neurologic impairment.”
The death cap is the world’s most poisonous mushroom, responsible for 90% of mushroom-related fatalities.
Where the death-cap outbreak is concentrated
When state public health officials first warned of the dangers of the death-cap mushroom in December, significant clusters of reported illness occurred in Monterey and the San Francisco bay areas.
Reported hospitalizations have since grown to include Alameda, Contra Costa, Monterey, San Francisco, San Luis Obispo, San Mateo, Santa Clara, Santa Cruz and Sonoma counties.
Death cap mushrooms are known to sprout across the state of California but they thrive in shady, humid or moist environments under live oak and cultivated cork oak trees.
Death cap mushrooms bloom particularly well after the fall and winter rains. Once they sprout, its tall and graceful characteristics are very conspicuous and catch people’s eye, said David Campbell, an expert on mushroom consumption or a mycophagist.
Who is mistakenly eating the death cap
People who have accidentally consumed the death cap were usually foraging for mushrooms in the wilderness, either alone or with a group, officials say.
Among the affected are monolingual speakers of Spanish, Chinese, Mandarin and Mixteco as well as foragers who may confuse the death cap mushroom for edible fungi from their native countries, according to experts.
“So they have a false sense of security in their knowledge, thinking they know what they’re doing but that only applies to where they’re from,” Campbell said.
“We’re seeing that a number of patients do seem to have a Hispanic background,” said Dr. Rita Nguyen, assistant state public health officer at the California Department of Public Health.
In November, a Salinas family said they went on a hike in their community and found the death cap which looked similar to an edible mushroom they would forage for in their hometown in Oaxaca, KSBW Action News reported.
Laura Marcelino and Carlos Diaz took the mushrooms home, cooked them and ate them — their children did not. They both threw up, had diarrhea for an entire day and were later hospitalized, KSBW Action News reported. Marcelino’s condition improved but Diaz’s health declined exponentially to the point that he fell into a coma and was put on a list to receive a liver transplant, according to news reports.
Why people are mistakenly eating death cap mushrooms
The three most deadly mushrooms in California include the death cap, destroying angel (Amanita ocreata) and deadly Galerina (Galerina marginata), according to the Bay Area Mycological Society.
The death cap mushroom has a dome-shape smooth cap with olive or yellowish-green tones. On the underside of its cap are white gills and spores.
It can be confused with the mushroom species Volvariella, which is edible.
These mushrooms appear similar because they have a volva, a cup-like structure at the base of the mushroom’s stem, and are white-ish, but lack one important key characteristic annulus, or ring, around its stem, said Ari Jumpponen, Kansas State University distinguished professor of biology.
Jumpponen said some Volvariella species can be found in Oaxaca.
What symptoms can you expect after eating a death cap?
No amount of death cap is safe to consume.
“I also want to just stress that there’s nothing, there’s no cooking of the mushroom or freezing of the mushroom that would inactivate the toxin,” Smollin said.
The poisonous toxins from the death cap can result in a delayed gastrointestinal symptoms that may not appear until 6 to 24 hours after eating it.
Some of the early symptoms that can go away within a day include:
- Nausea
- Vomiting
- Diarrhea
- Abdominal pain
- Drop in blood pressure
- Fatigue
- Confusion
Mild symptoms may only be the beginning of a more severe reaction.
Severe symptoms can develop within 48 to 96 hours, include progressive liver damage and, in some cases, full liver failure and potentially death, Smollin said.
If you’ve eaten a foraged mushroom and start to exhibit any adverse symptoms, call California’s poison control hotline at 1-800-222-1222 for free, confidential expert advice in multiple languages. If you suspect mushroom poisoning, call 911.

Leaked memo reveals California debated cutting wildfire soil testing before disaster chief’s exit
California Gov. Gavin Newsom’s disaster chief quietly retired in late December amid criticism over the state’s indecisive stance on whether soil testing was necessary to protect survivors of the Eaton and Palisades fires.
One year ago, Nancy Ward, then the director of the California Governor’s Office of Emergency Services (Cal OES), petitioned the Federal Emergency Management Agency to spearhead the cleanup of toxic ash and fire debris cloaking more than 12,000 homes across Los Angeles County.
Although Ward’s decision ensured the federal government would assume the bulk of disaster costs, it came with a major trade off. FEMA was unwilling to pay for soil sampling to confirm these homes weren’t still heavily contaminated with toxic substances after the cleanup — testing that California state agencies have typically done following similar fires in the past.
Following intense backlash from fire survivors and California lawmakers, Ward pleaded with FEMA to reconsider its soil-testing stance, writing in a Feb. 19 letter that it is “critical to protect public health” and “ensure that survivors can safely return to their homes.” Her request was denied.
However, in October, Cal OES — under Ward’s leadership — privately considered discontinuing state funding for soil testing in the aftermath of future wildfires, according to a confidential, internal draft memo obtained by the Los Angeles Times.
The Times requested an interview with Ward, and sent questions to her office asking about her initial decision to forgo soil testing and for clarity on the future of state’s fire recovery policy. Ward declined the request; The Times later published an article on Dec. 29 about allegations that federal contractors illegally dumped toxic ash and misused contaminated soil in breach of state policy.
Ward, who served as Cal OES director for three years, retired on Dec. 30; her deputy director, Christina Curry, stepped into the role as the interim chief. Ward also did not respond to several requests for comment for this article.
Ward was the first woman to serve as Cal OES director. She had also previously served as a FEMA regional administrator, overseeing federal disaster response in the Southwest and Pacific Islands from 2006 to 2014.
A Cal OES spokesperson said Ward’s retirement had been planned well in advance.
“Director Nancy Ward has been a steady hand and a compassionate leader through some of California’s largest disasters,” the spokesperson said. “Her decades of service have made our state stronger, safer, and more resilient. The Governor is deeply grateful for her dedication and wishes her the very best in retirement.”
The internal memo obtained by The Times was written by Ward’s assistant director, and titled: “Should the state continue to pay for soil testing as part of Private Property Debris Removal (PPDR) programs? ”
It laid out three possible answers: The state could keep funding soil testing after future wildfires; the state could defer soil testing decisions to the affected counties with the possibility of reimbursing them; or the state could stop paying for soil testing entirely.
A Cal OES spokesperson said the memo was only a draft and did not represent a policy change. “The state’s position on soil testing remains unchanged,” the spokesperson said. “California is committed to advocating for the safe, timely removal of wildfire debris. Protecting the public health and well-being of impacted communities remains the state’s foremost priority.”
The primary reason for soil testing is to prevent harmful exposures to toxic metals, such as brain-damaging lead or cancer-causing arsenic. Since 2007, comprehensive soil testing has been conducted after 64 wildfire cleanups in California, according to the memo. When soil contamination still exceeded state benchmarks after the initial cleanup, the state government redeployed cleanup workers to remove more dirt and then retest the properties.
This approach, the memo said, was critical in identifying harmful substances that “pose exposure hazards via ingestion, inhalation of dust, or through garden/food production.” Soil testing “helps ensure the safety” of children, seniors, pregnant women and people with health issues who are “more vulnerable to soilborne toxins.”
“The State has a long precedent of conducting or paying for soil testing,” the Cal OES assistant director wrote in the memo. “Pivoting from this would be a significant policy change.”
The memo cites a report from CalRecycle, the agency that has historically carried out state-led fire cleanups, that stresses the importance of the current practice to public health.
“Soil contamination after a wildfire is an invisible threat,” wrote a CalRecycle official. “If not properly cleaned and remediated in a methodical way, property owners may encounter additional hurdles during the rebuilding process and suffer additional trauma.”
“Soil sampling,” the official adds, “is the metric by which Recyclable demonstrates that debris removal operations have successfully remediated the post-disaster threat to public health and the environment.”
However, such soil testing and additional cleanup prolongs the cleanup timeline and can make it more expensive. The memo cites cost estimates from CalRecycle which show that soil testing and additional cleanup work usually costs some $4,000 to $6,000 per parcel, representing 3% to 6% of overall debris removal costs.
The state cost projections align with those made by independent environmental experts. Andrews Whelton, a Purdue University professor who researches natural disasters, estimated that soil testing and further remediation for the Eaton and Palisades fire would cost between $40 million to $70 million.
All told, the CalRecycle report states the usual soil-testing process has been a “relatively low-cost step” to safeguard public health.
Further, although soil testing may add some cost, when it’s taken as a proactive measure, it can save money down the road.
Forgoing soil testing and evidence-backed remediation can generate uncertainty about toxic contamination, which in turn could lower the value of homes in Altadena and Pacific Palisades, Whelton said. What’s more, the property owner may be liable for soil contamination if they fail to disclose environmental risks when selling or leasing.
The internal CalOES memo alludes to this give and take: “Funds saved initially by skipping testing may be outweighed by later unseen costs, for example, reinvesting in remediation, addressing community complaints, litigation, or cleanup failure.”
The U.S. Army Corps of Engineers has fielded over 1,100 complaints filed by property owners affected by the Eaton and Palisades fires — over 20% of which were related to the quality of work. According to internal reports obtained by The Times, federal cleanup repeatedly deviated from cleanup protocols, likely spreading contamination in the process.
Since then, FEMA officials have backed down from their hard-line stance against paying for post-fire soil testing in California in an attempt to shore up public confidence in the federal cleanup.
The U.S. Environmental Protection Agency announced this week that FEMA will conduct a limited lead-testing program in the Eaton fire burn scar that is intended to “confirm the effectiveness of cleanup methods,” according to an EPA spokesperson. The initiative has already come under the scrutiny of environmental experts who say it lacks the rigor of California’s soil testing regimen.
It remains unclear if California will continue to implement soil-testing safeguards that made the state a national leader in fire recovery. Though state officials say these will remain unchanged, there is no legal mandate to follow these procedures.
The internal CalOES memo circulated under Ward’s leadership has only added to the cloud of uncertainty.
One thing is clear: It’s a moot point for survivors of the Eaton and Palisades fire.
As state and federal officials debated the value of soil testing, most Altadena and Pacific Palisades residents have been left to investigate the extent of environmental fallout on their own.
