The agency will increase robotic missions to the moon and launch a spacecraft called Space Reactor 1 Freedom.

NASA has unveiled a major overhaul of its moon and Mars strategy, scrapping plans for a lunar-orbit space station and instead committing $20bn over the next seven years to build a base on the moon’s surface, while also advancing plans to send a nuclear-powered spacecraft to Mars.

NASA Administrator Jared Isaacman outlined the changes on Tuesday during a meeting in Washington, DC, with partners, contractors and government officials involved in the Artemis programme, saying the agency will increase robotic missions to the moon and lay the groundwork for nuclear power on the lunar surface.

Isaacman, appointed by US President Donald Trump and who took charge in December, said the changes form part of a broader overhaul of NASA’s long-term Moon-to-Mars strategy.

The planned moon base is intended to support long-term human presence on the lunar surface, with robotic missions expected to help prepare the site, test technologies and begin building infrastructure before astronauts return later this decade.

The agency also disclosed plans to launch a spacecraft called Space Reactor 1 Freedom before the end of 2028, a mission designed to demonstrate nuclear electric propulsion in deep space on the way to Mars.

The spacecraft will deliver helicopters on the Red Planet, similar to the Ingenuity robotic test helicopter that flew with NASA’s Perseverance rover, a step the agency said would help move nuclear propulsion technology from laboratory testing to operational space missions.

The Ingenuity helicopter was the first aircraft to achieve powered, controlled flight on another planet. It travelled to Mars attached to NASA’s Perseverance rover and landed in February 2021.

Pausing the Lunar Gateway station

The Lunar Gateway station, a planned space station in lunar orbit being developed with contractors including Northrop Grumman and international partners, was meant to serve as a base where astronauts could live and work before heading to the Moon’s surface.

But NASA now plans to repurpose some Gateway components for use on the surface instead.

Repurposing Lunar Gateway to create a base on the moon’s surface leaves uncertain the future roles of Japan, Canada and the ‌European Space ⁠Agency in the Artemis programme, three key NASA partners that had agreed to provide components for the orbital station.

“It should not really surprise anyone that we are pausing Gateway in its current form and focusing on infrastructure that supports sustained operations on the lunar surface,” Isaacman said.

The changes to NASA’s flagship Artemis programme are reshaping billions of dollars’ worth of contracts and come as the United States faces growing competition from China, which is aiming to land astronauts on the moon by 2030.

The Artemis programme, begun in 2017 during Trump’s first term as president, envisions regular lunar missions as NASA’s long-awaited follow-up to its first moon missions in the Apollo programme that ended in 1972.

Even as California’s soundstages suffer from a slowdown in local production, the local economy may get a boost from the state’s expanded film tax credits.

Medical drama “The Pitt,” a “Family Guy” spin-off and a kids’ science competition show from late-night host Jimmy Kimmel are among the 16 shows that received tax credits for filming in the state, the California Film Commission said Wednesday.

In total, the projects represent $871 million in qualified in-state spending and are expected to generate $1.3 billion in economic activity in California. More than 4,500 cast and crew members will be employed across the 16 shows, along with more than 50,000 background actors, the film commission said.

New to this round of awardees are animated shows and competitions, which were added to the film and television tax credit program during its revamp last year. Under the program, producers can receive up to 25% of qualified production expenses back in the form of credits that they can apply toward tax bills they have in the state.

“California’s creative economy isn’t just part of who we are — it helps power this state forward,” Gov. Gavin Newsom said in a statement. “From the folks on the soundstage to the people designing the sets, these are jobs that anchor communities.”

HBO Max’s “The Pitt” received a credit of $24.2 million, while “Stewie,” a spin-off of Seth MacFarlane’s irreverent adult cartoon “Family Guy,” was awarded $6.4 million. Kimmel’s “Schooled!” competition show, which pits young scientists and their experiments against one another, secured $6.9 million.

Since the state’s production incentive program was bolstered last year, more than 100 films and TV projects have received tax credits.

But it has taken a while for those shows to jump-start local production, which has seen a sustained slump since the pandemic, the dual writers’ and actors’ strikes in 2023 and spending cutbacks at the studios.

That lag has affected the business of local soundstages.

For the first half of 2025, the average occupancy rate at Los Angeles County soundstages was 62%, slightly lower than the 63% average recorded in 2024, according to new data from the nonprofit FilmLA, which tracks local production.

Those figures mark a significant decline from the average occupancy rate of 90% seen from 2016 to 2022, according to FilmLA data.

That’s been a problem for local soundstage operators, which had aggressively funded development of new properties or acquired them only to see production slow.

Earlier this year, Hackman Capital Partners said it was turning over the historic Radford Studio Center in Studio City to Goldman Sachs.

The US defence secretary designated the AI company a ‘supply chain risk’ after it refused to remove guardrails on its technology.

The administration of United States President Donald Trump has said in a court filing that the Pentagon’s blacklisting of Anthropic was justified and lawful, opposing the artificial intelligence company’s high-stakes lawsuit challenging the decision.

The administration made its comments in a court filing on Tuesday.

Defense Secretary Pete Hegseth designated Anthropic, the maker of popular AI assistant Claude, a national security supply chain risk on March 3 after the company refused to remove guardrails against its technology being used for autonomous weapons and domestic surveillance.

The Trump administration’s filing says Anthropic is unlikely to succeed in its claims that the US government’s action violated speech protections under the US Constitution’s First Amendment, asserting that the dispute stems from contract negotiations and national security concerns, not retaliation.

“It was only when Anthropic refused to release the restrictions on the use of its products — which refusal is conduct, not protected speech — that the President directed all federal agencies to terminate their business relationships with Anthropic,” the administration’s legal filing said. The filing, from the US Justice Department, said that “no one has purported to restrict Anthropic’s expressive activity”.

Anthropic’s lawsuit in California federal court asks a judge to block the Pentagon’s decision while the case plays out. Some legal experts say the company appears to have a strong case that the government overreached.

In a statement, Anthropic said it was reviewing the government’s filing. The company said that “seeking judicial review does not change our longstanding commitment to harnessing AI to protect our national security, but this is a necessary step to protect our business, our customers, and our partners.”

The White House did not immediately respond to a request for comment.

Supply chain risk

Trump has backed Hegseth’s move, which excludes Anthropic from a limited set of military contracts. But it could damage the company’s reputation and cause billions of dollars in losses this year, according to its executives.

The designation came after months of negotiations between the Pentagon and Anthropic reached an impasse, prompting Trump and Hegseth to denounce the company and accuse it of endangering American lives with its use restrictions.

Anthropic has disputed those claims and said AI is not yet safe enough to be used in autonomous weapons. The company said it opposes domestic surveillance as a matter of principle.

In its March 9 lawsuit, Anthropic said that the “unprecedented and unlawful” designation violated its free speech and due process rights, while running afoul of a law requiring federal agencies to follow specific procedures when making decisions.

The Pentagon separately designated Anthropic a supply chain risk under a different law that could expand the order to the entire government.

Anthropic is challenging that move in a second lawsuit in a Washington, DC, appeals court.

SACRAMENTO — California Gov. Gavin Newsom has positioned himself as a national public health leader by staking out science-backed policies in contrast with the Trump administration.

After Health and Human Services Secretary Robert F. Kennedy Jr. fired Centers for Disease Control and Prevention Director Susan Monarez for refusing what her lawyers called “the dangerous politicization of science,” Newsom hired her to help modernize California’s public health system. He also gave a job to Debra Houry, the agency’s former chief science and medical officer, who had resigned in protest hours after Monarez’s firing.

Newsom also teamed up with fellow Democratic governors Tina Kotek of Oregon, Bob Ferguson of Washington and Josh Green of Hawaii to form the West Coast Health Alliance, a regional public health agency, whose guidance the governors said would “uphold scientific integrity in public health as Trump destroys” the CDC’s credibility. Newsom argued establishing the independent alliance was vital as Kennedy leads the Trump administration’s rollback of national vaccine recommendations.

More recently, California became the first state to join a global outbreak response network coordinated by the World Health Organization, followed by Illinois and New York. Colorado and Wisconsin signaled they plan to join. They did so after President Trump officially withdrew the United States from the agency on the grounds that it had “strayed from its core mission and has acted contrary to the U.S. interests in protecting the U.S. public on multiple occasions.” Newsom said joining the WHO-led consortium would enable California to respond faster to communicable disease outbreaks and other public health threats.

Although other Democratic governors and public health leaders have openly criticized the federal government, few have been as outspoken as Newsom, who is considering a run for president in 2028 and is in his second and final term as governor. Members of the scientific community have praised his effort to build a public health bulwark against the Trump administration’s slashing of funding and scaling back of vaccine recommendations.

What Newsom is doing “is a great idea,” said Paul Offit, an outspoken critic of Kennedy and a vaccine expert who formerly served on the Food and Drug Administration’s vaccine advisory committee but was removed under Trump in 2025.

“Public health has been turned on its head,” Offit said. “We have an anti-vaccine activist and science denialist as the head of U.S. Health and Human Services. It’s dangerous.”

The White House did not respond to questions about Newsom’s stance and Health and Human Services declined requests to interview Kennedy. Instead, federal health officials criticized Democrats broadly, arguing that blue states are participating in fraud and mismanagement of federal funds in public health programs.

Health and Human Services spokesperson Emily Hilliard said the administration is going after “Democrat-run states that pushed unscientific lockdowns, toddler mask mandates, and draconian vaccine passports during the COVID era.” She said those moves have “completely eroded the American people’s trust in public health agencies.”

Public health guided by science

Since Trump returned to office, Newsom has criticized the president and his administration for engineering policies that he sees as an affront to public health and safety, labeling federal leaders as “extremists” trying to “weaponize the CDC and spread misinformation.” He has excoriated federal officials for erroneously linking vaccines to autism, warning that the administration is endangering the lives of infants and young children in scaling back childhood vaccine recommendations. And he argued that the White House is unleashing “chaos” on America’s public health system in backing out of the WHO.

The governor declined an interview request, but Newsom spokesperson Marissa Saldivar said it’s a priority of the governor “to protect public health and provide communities with guidance rooted in science and evidence, not politics and conspiracies.”

The Trump administration’s moves have triggered financial uncertainty that local officials said has reduced morale within public health departments and left states unprepared for disease outbreaks and prevention efforts. The White House last year proposed cutting Health and Human Services spending by $33 billion, including $3.6 billion from the CDC. Congress largely rejected those cuts last month, although funding for programs focusing on social drivers of health, such as access to food, housing and education, were axed.

The Trump administration announced that it would claw back more than $600 million in public health funds from California, Colorado, Illinois and Minnesota, arguing that the Democratic-led states were funding “woke” initiatives that didn’t reflect White House priorities. Within days, the states sued and a judge temporarily blocked the cut.

“They keep suddenly canceling grants and then it gets overturned in court,” said Kat DeBurgh, executive director of the Health Officers Assn. of California. “A lot of the damage is already done because counties already stopped doing the work.”

Federal funding has accounted for more than half of state and local health department budgets nationwide, with money going toward fighting HIV and other sexually transmitted infections, preventing chronic diseases, and boosting public health preparedness and communicable disease response, according to a 2025 analysis by KFF, a health information nonprofit that includes KFF Health News.

Federal funds account for $2.4 billion of California’s $5.3-billion public health budget, making it difficult for Newsom and state lawmakers to backfill potential cuts. That money helps fund state operations and is vital for local health departments.

Funding cuts hurt all

Los Angeles County public health director Barbara Ferrer said if the federal government is allowed to cut that $600 million, the county of nearly 10 million residents would lose an estimated $84 million over the next two years, in addition to other grants for prevention of HIV and other sexually transmitted infections. Ferrer said the county depends on nearly $1 billion in federal funding annually to track and prevent communicable diseases and combat chronic health conditions, including diabetes and high blood pressure. Already, the county has announced the closure of seven public health clinics that provided vaccinations and disease testing, largely because of funding losses tied to federal grant cuts.

“It’s an ill-informed strategy,” Ferrer said. “Public health doesn’t care whether your political affiliation is Republican or Democrat. It doesn’t care about your immigration status or sexual orientation. Public health has to be available for everyone.”

A single case of measles requires public health workers to track down 200 potential contacts, Ferrer said.

The U.S. eliminated measles in 2000 but is close to losing that status as a result of vaccine skepticism and misinformation spread by vaccine critics. The U.S. had 2,281 confirmed cases last year, the most since 1991, with 93% in people who were unvaccinated or whose vaccination status was unknown. This year, the highly contagious disease has been reported at schools, airports and Disneyland.

Public health officials hope the West Coast Health Alliance can help counteract Trump by building trust through evidence-based public health guidance.

“What we’re seeing from the federal government is partisan politics at its worst and retaliation for policy differences, and it puts at extraordinary risk the health and well-being of the American people,” said Georges Benjamin, executive director of the American Public Health Assn., a coalition of public health professionals.

Robust vaccine schedule

Erica Pan, California’s top public health officer and director of the state Department of Public Health, said the West Coast Health Alliance is defending science by recommending a more robust vaccine schedule than the federal government. California is part of a coalition suing the Trump administration over its decision to rescind recommendations for seven childhood vaccines, including for hepatitis A, hepatitis B, influenza and COVID-19.

Pan expressed deep concern about the state of public health, particularly the uptick in measles. “We’re sliding backwards,” Pan said of immunizations.

Sarah Kemble, Hawaii’s state epidemiologist, said Hawaii joined the alliance after hearing from pro-vaccine residents who wanted assurance that they would have access to vaccines.

“We were getting a lot of questions and anxiety from people who did understand science-based recommendations but were wondering, ‘Am I still going to be able to go get my shot?’” Kemble said.

Other states led mostly by Democrats have also formed alliances, with Pennsylvania, New York, New Jersey, Massachusetts and several other East Coast states banding together to create the Northeast Public Health Collaborative.

Hilliard, of Health and Human Services, said that even as Democratic governors establish vaccine advisory coalitions, the federal Advisory Committee on Immunization Practices “remains the scientific body guiding immunization recommendations in this country, and HHS will ensure policy is based on rigorous evidence and gold standard science, not the failed politics of the pandemic.”

Influencing red states

Newsom, for his part, has approved a recurring annual infusion of nearly $300 million to support the state Department of Public Health, as well as the 61 local public health agencies across California, and last year signed a bill authorizing the state to issue its own immunization guidance. It requires health insurers in California to provide patient coverage for vaccinations the state recommends even if the federal government doesn’t.

Jeffrey Singer, a doctor and senior fellow at the libertarian Cato Institute, said decentralization can be beneficial. That’s because local media campaigns that reflect different political ideologies and community priorities may have a better chance of influencing the public.

A KFF analysis found some red states are joining blue states in decoupling their vaccine recommendations from the federal government’s. Singer said some doctors in his home state of Arizona are looking to more liberal California for vaccine recommendations.

“Science is never settled, and there are a lot of areas of this country where there are differences of opinion,” Singer said. “This can help us challenge our assumptions and learn.”
