By executive order last month, Donald Trump launched his so-called “Genesis Mission.” Described as a “historic national effort” to “invest in AI-enabled science to accelerate scientific advancement,” Trump claimed his mission would address key challenges to American energy dominance, innovation, and national security. This mission, Trump boasted, would be a game-changer to science akin to putting a man on the moon or firing the first nuclear weapons. By building “an integrated AI platform” trained on Continue Reading“A Band-Aid on a giant gash”: Trump’s attacks on science may ruin his AI moonshot→

LAUNCH COMPLEX 14, Cape Canaveral, Fla.—The platform atop the hulking steel tower offered a sweeping view of Florida’s rich, sandy coastline and brilliant blue waves beyond. Yet as captivating as the vista might be for an aspiring rocket magnate like Andy Lapsa, it also had to be a little intimidating. To his right, at Launch Complex 13 next door, a recently returned Falcon 9 booster stood on a landing pad. SpaceX has landed more than Continue ReadingStoke Space goes for broke to solve the only launch problem that “moves the needle”→

About 170 Starshield satellites built by SpaceX for the US government’s National Reconnaissance Office (NRO) have been sending signals in the wrong direction, a satellite researcher found. The SpaceX-built spy satellites are helping the NRO greatly expand its satellite surveillance capabilities, but the purpose of these signals is unknown. The signals are sent from space to Earth in a frequency band that’s allocated internationally for Earth-to-space and space-to-space transmissions. There have been no public complaints Continue ReadingUS spy satellites built by SpaceX send signals in the “wrong direction”→

Science fiction has long speculated about the possibility of first contact with an alien species from a distant world and how we might be able to communicate with them. But what if we simply don’t have enough common ground for that to even be possible? An alien species is bound to be biologically very different, and their language will be shaped by their home environment, broader culture, and even how they perceive the universe. They Continue ReadingWhat if the aliens come and we just can’t communicate?→

After a long summer and fall of uncertainty, private astronaut Jared Isaacman has been renominated to lead NASA, and there appears to be momentum behind getting him confirmed quickly as the space agency’s 15th administrator. It is possible, although far from a lock, the Senate could finalize his nomination before the end of this year. It cannot happen soon enough. The National Aeronautics and Space Administration is, to put it bluntly, kind of a mess. Continue ReadingNASA is kind of a mess: Here are the top priorities for a new administrator→

When the first foldable phones came along, they seemed like a cool evolution of the traditional smartphone form factor and, if they got smaller and cheaper, like something people might actually want. After more than five years of foldable phones, we can probably give up on the latter. Google’s new Pixel 10 Pro Fold retains the $1,800 price tag of last year’s model, and while it’s improved in several key ways, spending almost two grand Continue ReadingGoogle Pixel 10 Pro Fold review: The ultimate Google phone→

SpaceX’s $17 billion deal to buy spectrum licenses from EchoStar should help Starlink satellites deliver better service to smartphones, and it might give a few large corporations second thoughts about their current partnerships with Starlink competitors. The spectrum, combined with a SpaceX plan to launch up to 15,000 new and improved satellites for cellular service, could cause AT&T and Verizon to question their reliance on satellite company AST SpaceMobile. Apple, which was reportedly already facing Continue ReadingElon Musk tries to make Apple and mobile carriers regret choosing Starlink rivals→

For the last month, NASA’s interim administrator, Sean Duffy, has been giving interviews and speeches around the world, offering a singular message: “We are going to beat the Chinese to the Moon.” This is certainly what the president who appointed Duffy to the NASA post wants to hear. Unfortunately, there is a very good chance that Duffy’s sentiment is false. Privately, many people within the space industry, and even at NASA, acknowledge that the US Continue ReadingHow America fell behind China in the lunar space race—and how it can catch back up→

How calm, cool, and utterly chill is the crew of NASA’s first Moon mission in more than half a century? Let’s start with Canadian astronaut Jeremy Hansen. “You know me, personally, I hope to take a very short nap on the pad,” he said. “There’s enough time built in there to have a nap. I’ve been practicing falling asleep. So if the loops are quiet enough, and I get a minute, I’ll try for a Continue ReadingIn their own words: The Artemis II crew on the frenetic first hours of their flight→

STARBASE, Texas—I first visited SpaceX’s launch site in South Texas a decade ago. Driving down the pocked and barren two-lane road to its sandy terminus, I found only rolling dunes, a large mound of dirt, and a few satellite dishes that talked to Dragon spacecraft as they flew overhead. A few years later, in mid-2019, the company had moved some of that dirt and built a small launch pad. A handful of SpaceX engineers working Continue ReadingSpaceX has built the machine to build the machine. But what about the machine?→

US defense officials have long worried that China’s Guowang satellite network might give the Chinese military access to the kind of ubiquitous connectivity US forces now enjoy with SpaceX’s Starlink network. It turns out the Guowang constellation could offer a lot more than a homemade Chinese alternative to Starlink’s high-speed consumer-grade broadband service. China has disclosed little information about the Guowang network, but there’s mounting evidence that the satellites may provide Chinese military forces a Continue ReadingChina’s Guowang megaconstellation is more than another version of Starlink→

The first foldable phones hit the market six years ago, and they were rife with compromises and shortcomings. Many of those problems have persisted, but little by little, foldables have gotten better. With the release of the Galaxy Z Fold 7, Samsung has made the biggest leap yet. This device solves some of the most glaring problems with Samsung’s foldables, featuring a new, slimmer design and a big camera upgrade. Samsung’s seventh-generation foldable has finally Continue ReadingSamsung Galaxy Z Fold 7 review: Quantum leap→

Order in the court! Order in the court! Judges are facing outcry over a suspected AI-generated order in a court. Fueling nightmares that AI may soon decide legal battles, a Georgia court of appeals judge, Jeff Watkins, explained why a three-judge panel vacated an order last month that appears to be the first known ruling in which a judge sided with someone seemingly relying on fake AI-generated case citations to win a legal fight. Now, Continue ReadingIt’s “frighteningly likely” many US courts will overlook AI errors, expert says→

After so many delays, difficulties, and disappointments, you might be inclined to think that NASA wants to wash its hands of Boeing’s troubled Starliner spacecraft. But that’s not the case. The manager of NASA’s commercial crew program, Steve Stich, told reporters Thursday that Boeing and its propulsion supplier, Aerojet Rocketdyne, are moving forward with several changes to the Starliner spacecraft to resolve problems that bedeviled a test flight to the International Space Station (ISS) last Continue ReadingDespite chronic letdowns, NASA just can’t quit Boeing’s Starliner→

Russia is a waning space power, but President Vladimir Putin has made sure he still has a saber to rattle in orbit. This has become more evident in recent weeks, when we saw a pair of rocket launches carrying top-secret military payloads, the release of a mysterious object from a Russian mothership in orbit, and a sequence of complex formation-flying maneuvers with a trio of satellites nearly 400 miles up. In isolation, each of these Continue ReadingIt’s hunting season in orbit as Russia’s killer satellites mystify skywatchers→

A little less than four years from now, a killer asteroid will narrowly fly past planet Earth. This will be a celestial event visible around the world—for a few weeks, Apophis will shine among the brightest objects in the night sky. The near miss by the large Apophis asteroid in April 2029 offers NASA a golden—and exceedingly rare—opportunity to observe such an object like this up close. Critically, the interaction between Apophis and Earth’s gravitational Continue ReadingAn exceedingly rare asteroid flyby will happen soon, but NASA may be left on the sidelines→

In recent years, a curious hypothetical particle called the axion, invented to address challenging problems with the strong nuclear force, has emerged as a leading candidate to explain dark matter. Although the potential for axions to explain dark matter has been around for decades, cosmologists have only recently begun to seriously search for them. Not only might they be able to resolve some issues with older hypotheses about dark matter, but they also offer a Continue ReadingThe axion may help clean up the messy business of dark matter→

Bridgit Mendler was not in Hollywood anymore. Instead, she found herself in rural North Dakota, where the stars sparkled overhead rather than on the silver screen. And she was freezing. When her team tumbled out of their rental cars after midnight, temperatures had already plummeted into the 40s. Howling winds carried their breath away before it could fog the air. So it was with no small sense of urgency that the group scrambled to assemble Continue ReadingShe was a Disney star with platinum records, but Bridgit Mendler gave it up to change the world→

Last week, Google introduced Veo 3, its newest video generation model that can create 8-second clips with synchronized sound effects and audio dialog—a first for the company’s AI tools. The model, which generates videos at 720p resolution (based on text descriptions called “prompts” or still image inputs), represents what may be the most capable consumer video generator to date, bringing video synthesis close to a point where it is becoming very difficult to distinguish between Continue ReadingAI video just took a startling leap in realism. Are we doomed?→

SpaceX fired six Raptor engines on the company’s next Starship rocket Monday, clearing a major hurdle on the path to launch later this month on a high-stakes test flight to get the private rocket program back on track. Starship ignited its Raptor engines Monday morning on a test stand near SpaceX’s Starbase launch facility in South Texas. The engine ran for approximately 60 seconds, and SpaceX confirmed the test-firing in a post on X: “Starship Continue ReadingAfter back-to-back failures, SpaceX tests its fixes on the next Starship→
