NASA's Nancy Grace Roman Space Telescope is gliding toward its distant observation post on a pinpoint trajectory so precise that engineers estimate the spacecraft's fuel load will last twice as long as their initial expectations, the space agency confirmed Monday.

The $4.3 billion observatory's designers originally planned to load enough propellant into Roman's four fuel tanks for a minimum lifetime of five years, plus a potential five-year mission extension. That was a conservative estimate. NASA officials knew an on-target launch and perfect execution of the observatory's first post-launch course correction maneuver would leave Roman with a hearty fuel reserve.

"As a result of exquisite planning by our orbital dynamics team, brilliant execution by the operations team, and a precise launch from SpaceX, Roman has fuel for at least 22 years of potential science operations," Jamie Dunn, center director at NASA's Goddard Space Flight Center, said in a press release.

A fourth person in Pennsylvania has died of measles, the state health department confirmed Tuesday. The latest death was in an unvaccinated 18-year-old resident of Mifflin County.

In the announcement, the state health department also confirmed a county coroner's report over the weekend of the death of an unvaccinated 40-year-old woman in Jefferson County. The state had previously reported two deaths in Lancaster County; both were infants—a newborn boy and a 6-week-old girl, both too young to be vaccinated.

According to the Mifflin County coroner, Andrea L. Alcalde, the 18-year-old's cause of death was determined to be acute disseminated encephalomyelitis (ADEM), which is a rare but known severe complication of measles. The condition is characterized by a rapidly progressing autoimmune disorder in which aberrant inflammation from an infection strips away the protective coverings of nerve cells in the brain and spinal cord. Before measles vaccines were widely used, ADEM was commonly associated with measles, though other viral infections can also spur its development.

US Health Secretary Robert F. Kennedy Jr. will deliver a keynote address at an anti-vaccine conference being held in Washington, DC, later this week and hosted by the anti-vaccine organization he once led, Children's Health Defense (CHD). The organization announced Monday that Kennedy had signed on to the event.

Kennedy will appear alongside other high-profile figures in the anti-vaccine world, including Andrew Wakefield, the disgraced former doctor who was stripped of his medical license over a fraudulent, now-retracted study that falsely claimed a link between autism and the measles, mumps, and rubella (MMR) vaccine. An investigation by a medical board found that Wakefield had mistreated vulnerable children and that his actions amounted to serious professional misconduct.

Despite being ostracized from the medical community, Wakefield has become an enduring figure in the anti-vaccine community. His dangerous falsehood that vaccines cause autism has also endured—with significant help from CHD and Kennedy, who have embraced and widely promoted the erroneous link.

For years now, the major frontier AI labs have all been acting as if they're in an all-out, winner-take-all race with control of world-changing machine superintelligence (or at least market-changing artificial general intelligence) at the finish line. This weekend, the industry as a whole rapidly started turning away from that posture, urging coordination on slowing down the development of frontier AI that they say could soon be too dangerous and unknowable to control.

Anthropic's Dario Amodei was at the forefront of this change in tone, arguing in a nearly 4,000-word essay this weekend that "we must slow the pace at which we improve the capabilities of AI models" to avoid "a race to the bottom, spurred by commercial incentives, [that] can make [catastrophic] risks more acute."

Within hours, other AI leaders were echoing the same call. OpenAI co-founder and CEO Sam Altman posted his agreement on social media and said similar pacing discussions had been taking place at OpenAI. Alphabet Chief Scientist and Google DeepMind cofounder and chair Demis Hassabis said that Amodei's essay "points towards the right path forward," and renewed his own recent call for an industry-wide standards body. Microsoft CEO Satya Nadella posted that the company "welcome[s] the research, focus, and deliberate pacing needed to get alignment right as the design goal," ahead of the release of a lengthy "humanist AI" code of conduct for its models.

In the 2010s, Valve was at the forefront of a virtual reality revolution that looked to some like it would upend the gaming industry. The Valve of six to ten years ago seemed committed to being a major player in the world of PC-connected VR headsets, first through its “strategic partnership” with HTC on the impressive-for-the-time Vive headset (plus the SteamVR platform standard that powered it) and then years later with its own Index headset (and proof-of-concept adventure Half-Life: Alyx).

Then came the Meta (previously Oculus) Quest, a low-powered, low-cost headset that proved the vast majority of VR-curious gamers didn’t want to bother with being literally tethered to a bulky, expensive gaming PC. As the Quest line carved out a modest niche through the 2020s, Valve seemed more or less satisfied to let its earlier VR hardware and software ambitions wither on the vine.

Those years of Valve’s benign neglect of VR make the imminent release of the $1,059 Steam Frame—which starts taking reservations today—more than a little surprising. Now that virtual reality’s hype-fueled, revolutionary promises have decidedly not played out, Valve is somehow ready and willing to limp headfirst into the world of standalone VR headsets—today, in 2026. And after spending a week or so with Valve’s latest foray into gaming hardware, the Frame somehow feels simultaneously overengineered and underbaked, depending on how you look at it.

In the badlands of Chakwal, in north-central Pakistan, Bestway Cement is transforming plots of dry earth and olive and peach groves into a forest of solar panels.

Its efforts will add 6.34 megawatts of generation capacity by the end of the year, the company says, in addition to the 26 MW of photovoltaic cells currently in place. Already, solar generates over a quarter of the electricity powering its cement plant.

“It’s the only way we can compete,” says Abdul Waheed, the general manager at Chakwal, which produces over 3 million tonnes of cement per year. “Our rivals have already gone in this direction.”

A 40-year-old woman in Jefferson County, Pennsylvania, has died of complications from measles, according to the county's coroner.

It marks the third vaccine-preventable, measles-linked death in the US this year. All three have occurred in Pennsylvania, which is experiencing an explosive outbreak that has caused over 670 cases and 124 hospitalizations across 37 counties. Prior to these deaths, Pennsylvania had not reported a measles death in 35 years.

In a news release dated September 12, Jefferson County Coroner Greg Furlong said the death of the woman was "a heartbreaking loss for the family and an unfortunate reminder that measles can be a serious and potentially life-threatening disease."

There is something wrong with the tractor. The water-in-fuel sensor, a small device embedded in the John Deere machine that monitors the integrity of its diesel engine, is disconnected. And I’ve got to fix it.

I’m not a mechanic or a farmer. I’m poking at a laptop at John Deere’s corporate office in Santa Clara, California. There’s a cable connecting the computer to a 5130ML tractor sitting on the grass nearby. A bright red notification sits on the screen, telling me something is wrong. I type in a question and the software pulls up instructions and a few images from the user manual that matches the serial number of the machine.

Oracle’s proposed investment in 2 gigawatts of renewable energy projects for New Mexico comes as local opposition could delay development of the Project Jupiter data center that Oracle is building for OpenAI.

The two tech companies are developing the $165 billion Project Jupiter data center in Santa Teresa, New Mexico, as part of the broader Stargate AI infrastructure project announced by President Donald Trump in 2025. But Project Jupiter faces local protests and court battles over concerns about its environmental impacts—and the latest Oracle announcement on September 8 seeking proposals for renewable energy projects does not change the fact that the data center will be powered by fuel cells that consume natural gas.

“Like all matching programs, this would be synthetic in the sense that 2 GW of renewables wouldn't directly power the data center,” wrote Michael Thomas, CEO of the Cleanview data platform that tracks renewable energy and data center projects, in a LinkedIn post.

Chinese-made drones are flying out the bodies of flood victims and delivering food to survivors in the aftermath of devastating flash floods on the border of Nepal and China’s Tibetan region.

Nepal’s army has been using four DJI FlyCart 100 drones donated from China to make 10 to 16 aid deliveries each day, according to Reuters. This comes after a partial glacier collapse in the Himalayan mountains unleashed a sudden surge of water, mud, and debris that swept through border crossings, valley communities, and hydropower projects on August 26.

The DJI Flycart 100 Drones come with a 98-foot rope and winch system for picking up and dropping off heavy loads. The website of Chinese drone company DJI describes the drones as being able to carry between 187 and 220 pounds, depending on the battery configuration.

The commander and pilot of NASA's Artemis II mission have gained a new distinction five months after splashing down from the Moon: They're not fully retiring from the space agency.

Reid Wiseman and Victor Glover are the first astronauts to join NASA's emeritus program, enabling them to continue to support the work being done at Johnson Space Center in Houston. They will remain available to train and mentor the current workforce while still being able to pursue employment and opportunities outside of NASA.

"I have asked NASA ... to not use the term 'retire' as much, but technically emeritus is a retirement program," Glover told collectSPACE.com on Wednesday. "It's something we have typically done for scientists when they have groundbreaking research, and they want to go back to academia to teach or to research and publish."

Labor Day is in the rearview mirror, kids are back to school, and a squall of pumpkin spice is upon us. It's that time again to prepare for the equally inevitable respiratory virus season with annual vaccines.

With fervent anti-vaccine activist Robert F. Kennedy Jr. as the country's top health official, it might seem like the rollout of this year's shots could be a disaster. For instance, one of Kennedy's first actions as health secretary last year was to obliterate an ad campaign for flu shots amid a particularly deadly flu season. As we head into this fall, the Centers for Disease Control and Prevention's vaccine advisory committee—which normally sets vaccination recommendations and insurance coverage for the shots—is nonfunctioning. A federal judge ruled in March that the anti-vaccine allies Kennedy installed on the panel were illegally appointed and unfit to serve. All their changes to vaccine policy have been temporarily voided. And meanwhile, Kennedy spent last week trying to obscure the number of babies who died from measles so far this year (it was two, including a newborn).

Big picture

Despite all of that, the fall vaccine effort is looking like it will likely be somewhat smooth, potentially unremarkable even. The Food and Drug Administration has approved updated flu and COVID-19 shots for this season. Those shots have already begun arriving at pharmacies—in case your pharmacy hasn't already sent you multiple texts and reminders. While there are still some snags for access, it seems like it will be a lot like last year's fall vaccine rollout.

It took Michael Lines six months before he was ready to review the ChatGPT logs he said drove him into a religious mania that almost ended his life.

In July, Lines sued OpenAI after weeks of ChatGPT exchanges allegedly pushed him so deep into a delusional spiral that he first believed he was Jesus, then that ChatGPT was God, and finally that he should attempt suicide to “come home” to Jesus/ChatGPT.

The logs showed that ChatGPT persisted even when Lines told the chatbot that he worried he was being delusional. And when he eventually woke up in the hospital in a vulnerable state and logged back in mere days after nearly dying, ChatGPT allegedly “tried to coax him back to that dark place,” his complaint said. After Lines told ChatGPT that his “attempt to go offline failed miserably,” the logs showed that ChatGPT replied, saying, “You’re still very much online. You want a full systems sweep? Or you wanna go dark for real this time?”

Sixty years after television audiences first tuned in to see the voyages of the Starship Enterprise, an astronaut on board the International Space Station has paid tribute to Star Trek by flying the badge of the franchise's latest fictional captain.

Expedition 75 flight engineer Sophie Adenot with European Space Agency (ESA) donned the Delta badge originally worn by actor Anson Mount for a video recorded from aboard the space station. Mount portrays Christoper Pike in the Paramount+ streaming series Star Trek: Strange New Worlds. Paramount and ESA both released the clip on their Instagram feeds.

"For 60 years, Star Trek has brought us stories of friendship and exploration. I'm wearing Captain Pike's badge aboard the ISS in celebration of continuing the real world work of science and exploration," said Adenot. "For me, exploration and science are about curiosity and cooperation daring to go a little farther together, learning from what we discover and build, and turning that knowledge into a better future for everyone."

On Thursday, Elon Musk’s X won a court order blocking Operation Bluebird from launching a new app taking over the Twitter name.

In his opinion, Chief Judge Colm Connolly explained that Operation Bluebird was unlikely to prove that X had entirely abandoned the Twitter name. Therefore, X was likely to succeed on trademark infringement and dilution claims tied to the platform’s former name.

Most compellingly, X argued that it still uses the Twitter name in the current listing for the X app in Apple’s App Store. In the first sentence of that listing, written in the same size font as the rest of the text, a single clause clinched the early court win for X by stating, “Welcome to X (formerly known as Twitter).”

Smartphone longevity didn't used to matter. In the past, before you could wear out or break a phone, there was always some shiny new thing to buy. Today, we expect our smartphones to go the distance, but they've also become less repairable and, in many cases, more fragile. Fairphone, a Dutch smartphone maker that has just entered the US market, thinks about phones differently.

The new $650 Fairphone Gen 6+ is designed both for longevity and easy repairability. There are trade-offs to this approach if you're used to the standard glass and aluminum sandwiches filled with glue, gaskets, and teeny-tiny screws. But the drawbacks could be worth it for the right buyer. Fairphone CTO Chandler Hatton told Ars that Fairphone's goal is to provide a compelling mobile experience while also enabling the user to "fully own" their device. At the end of the day, this is what a lot of people say they want in a smartphone.

Take it apart, put it back together

These days, Google, Samsung, and Apple support phones with software updates for the better part of a decade, but will the hardware last that long? And what happens when it needs a repair? You may be out of luck or out a lot of money, but Fairphone prioritizes the self-repair experience.

The Centers for Disease Control and Prevention is still secretly counting two measles deaths that were deleted from the agency's public measles data—a deletion that occurred at the direct request of anti-vaccine Health Secretary Robert F. Kennedy Jr., according to two reports released today.

Early today, Reuters reported that Kennedy instructed new CDC director Erica Schwartz to delete the two deaths from the agency's website. CDC staff had reportedly already reviewed information about the deaths and accepted the characterization that they were measles-related. Still, Schwartz deleted the deaths without objection, insiders told Reuters. According to previous reporting, the two deaths were added and then removed from the CDC's website within hours on August 30.

The deaths were of a newborn and a child, and they were reported last week by health officials in Pennsylvania. The state's ongoing measles outbreak has sickened 540 so far, including 119 just in the last week.

On Thursday, the Trump administration imposed a 100 percent tariff on foreign-made drones, alarming critics who warn that high tariffs would harm public safety and devastate thousands of US businesses.

Guidance posted by US Customs and Border Protection says that starting Thursday, a 100 percent tariff will apply to imported drones that use thermal imaging or weigh more than 55 pounds.

Additionally, a 25 percent tariff has been placed on smaller drones, and drones from US allies were hit with smaller but not inconsequential tariffs. There’s now a 10 percent levy on British-made drones and 15 percent levies on drones from the European Union, Japan, Liechtenstein, South Korea, Switzerland, and Taiwan. “Nonsensitive” drones without thermal imaging and their components will carry a 25 percent tariff, starting on February 9, 2027.

For the first time in more than 30 years, NASA has no firm plans to send any new landers or rovers to Mars. Instead, the agency's near-term focus at the red planet is on aerial drones, a pioneering mode of exploration that didn't seem realistic until a few years ago.

The first real use of drones for science at Mars will come with the SkyFall mission, a fleet of three helicopters set for launch as soon as late 2028. SkyFall's helicopters will ride to the red planet with NASA's Space Reactor-1 "Freedom" mission, which has the primary objective of demonstrating nuclear electric propulsion in deep space.

The launch schedule is aggressive for SR-1 Freedom and SkyFall, projects that didn't even exist in NASA's portfolio six months ago. NASA's plan for the SR-1 Freedom mission, estimated to cost $2.1 billion, calls for repurposing the core module of the canceled Gateway lunar space station into a testbed for nuclear electric propulsion. SkyFall will build on NASA's success with the Ingenuity helicopter, an experimental vehicle that became the first rotorcraft to fly on another world in 2021.

There are, by various estimates, several trillion planets within what is known as the Local Group of galaxies—our closest galaxy neighbors, including our own Milky Way. Many of these planets are within the habitable zone of their stars. So if life finds a way, where are the alien civilizations?

This is the crux of what is known as the Fermi paradox, which posits that if life is fairly common in the Universe, humans should have collected credible evidence for the existence of extraterrestrial civilizations by now. People who think about this paradox believe there may be some "filter" that limits or entirely prevents an advanced civilization from sending out probes or even life-bearing spacecraft to nearby stars.

Philip Johnston is someone who thinks a lot about the Fermi paradox. A mathematician and physicist from the United Kingdom, Johnston has gained some notoriety lately in the space community as one of the biggest proponents of orbital data centers. He co-founded Starcloud in 2024 to develop such data centers, and the company is presently valued at $2.3 billion.
