Gouach wants you to insert and pluck the cells from its Infinite e-bike battery

“It was really a setback for the company [Gouach] at the time,” Vallette said. “But we knew that the technology itself was good, so we designed our own casing.” Gouach’s casing is now rated IP67, Vallette said, and meets UL 2271 standards.

Unexpected resistance

There are three avenues for selling the Infinite Battery, as Vallette sees it. One is working with e-bike makers to incorporate Gouach’s tech. Another is targeting e-bike owners and small bike shops who, this far into e-bikes’ history, might be dealing with dead batteries. And then there are folks looking to build their own e-bikes.

The Infinite Battery will be made available in 36 V and 48 V builds, and Gouach’s app promises to help owners connect it to a wide variety of bikes. Actually fitting the battery case onto your bike is a different matter. Some bikes can accommodate the Gouach kit where their current battery sits, while others may end up mounting to a rack, or through creative, but hopefully secure, frame attachments.

One of the biggest compatibility challenges, Vallette said, was finding a way to work with Bosch’s mid-drive motors. The communications between a Bosch motor and battery are encrypted; after “a serious effort,” Gouach’s app and battery should work with them, Vallette said.

Gouach, having raised more than $220,000 on crowdfunding platform Indiegogo from about 500 backers, and $3.5 million in venture funding, is getting close to offering the batteries through its own storefront. Gouach’s roadmap puts them in mass production at the moment, with assorted bugs, certifications, and other matters to clear. EU-based backers should get their kits in June, with the US, and an open online store, to follow, barring whatever happens next in international trade. Vallette said in mid-May that the US’s momentary 145 percent tariffs on Chinese imports disrupted their plans, but work was underway.

If nothing else, Gouach’s DIY kit shows that a different way of thinking about e-bike batteries—as assemblages, not huge all-in-one consumables—is possible.

Trump’s trade war risks splintering the Internet, experts warn


Trump urged to rethink trade policy to block attacks on digital services.

In sparking his global trade war, Donald Trump seems to have maintained a glaring blind spot when it comes to protecting one of America’s greatest trade advantages: the export of digital services.

Experts have warned that the consequences for Silicon Valley could be far-reaching.

In a report released Tuesday, an intelligence firm that tracks global trade risks, Allianz Trade, shared results of a survey of 4,500 firms worldwide, designed “to capture the impact of the escalation of trade tensions.” Amid other key findings, the group warned that the US’s fixation on the country’s trillion-dollar goods deficit risks rocking “the fastest-growing segment of global trade,” America’s “invisible exports” of financial and digital services.

Tracking these exports is challenging, as many services are provided through foreign affiliates, the report noted, but recent estimates “reveal a large digital trade surplus of at least $600 billion for the US, spread across categories like digital advertising, video streaming, cloud platforms, and online payment services.”

According to Allianz Trade, “the scale of this hidden trade is immense.” These “hidden” exports have “far” outpaced “the growth of goods exports over the past two decades, their report said, but because of how these services are delivered, “this trade goes uncounted in traditional statistics.”

If Trump doesn’t “rethink trade policy and narratives” soon to start tracking all this trade more closely, he risks undermining this trade advantage—which Allianz Trade noted “is underpinned by America’s innovative firms and massive data infrastructure”—at a time when he’s in trade talks with most of the world and could be leveraging that advantage.

“US digital exports now represent a significant share of world trade (about 3.6 percent of all global trade, and growing fast),” Allianz Trade reported. “These ‘invisible’ exports boost US trade revenues without filling any container ships, underscoring a new reality: routers and data centers are as strategically important as ports and factories in sustaining US leadership.”

Without a pivot, Trump’s current trade tactics—requiring all countries impacted by reciprocal tariffs to strike a deal before July 8, while acknowledging that there won’t be time to meet with every country—could even threaten US dominance as “the world’s digital content and tech services hub,” Allianz Trade suggested.

US trade partners are already “looking into tariffs or taxes on digital services as a retaliation tool that could cause pain to the US,” the report warned. And other experts agreed that if such countermeasures become permanent fixtures in global trade, it could significantly hurt the US tech industry, perhaps even splintering the Internet, as companies are forced to customize services according to where different users are located.

Jovan Kurbalija, a former diplomat and executive director of the DiploFoundation who has monitored the Internet’s impact on global trade for more than 20 years, warned in an April blog that this could have a “more profound impact” on the US than other retaliatory measures.

“If the escalation of trade tensions moves into the digital realm, it could have far-reaching consequences for Silicon Valley giants and the digital economy worldwide,” Kurbalija wrote.

“The silent war over digital services”

The threat of retaliatory tariffs hitting the digital services industry has loomed large since European Commission President Ursula von der Leyen confirmed to the Financial Times last month that she was proactively developing such countermeasures if Trump’s trade talks with the European Union failed.

Those measures could potentially include “a tax on digital advertising revenues that would hit tech groups such as Amazon, Google and Facebook,” the FT reported. But perhaps most alarmingly, they may also include “tariffs on the services trade between the US and the EU.” Unlike the digital sales tax—which could be imposed differently by EU member states to significantly hurt tech giants’ ad revenues in various regions—the tariff would be applied across a single EU-wide market.

Kurbalija suggested that the problem goes beyond the EU.

Trump’s aggressive tariffs on goods have handed “the EU and others both moral and tactical pretexts to fast-track digital taxes” as countermeasures, Kurbalija wrote. He’s also given foreign governments an appealing narrative of “reclaiming revenue from foreign tech ‘free riders,'” Kurbalija wrote, while perhaps accelerating the broader “use of digital service taxes as a diplomatic tool” to “pressure the US into balanced negotiations.”

For tech companies, the taxes risk escalating trade tensions, potentially perpetuating the atmosphere of uncertainty that, Allianz Trade reported, has US firms scrambling to secure reliable, affordable supply chains.

In an op-ed discussing potential harms to US tech firms and startups, the CEO of CareYaya Health Technologies, Neal K. Shah, warned that “tariffs on digital services would directly reduce revenues for American tech companies.”

At the furthest extreme, the “digital trade war threatens to splinter the Internet’s integrated infrastructure,” Kurbalija warned, fragmenting the Internet in a way that could “undermine decades of gradual development of technological interconnectedness.”

Imagine, Shah suggested, that on top of increased hardware costs, tech companies also incurred costs of providing services for “parallel digital universes with incompatible standards.” Users traveling to different locations might find that platforms have “different features, prices, and capabilities,” he said.

“For startups and industry innovators,” Shah predicted, “fragmentation means higher compliance costs, reduced market access, and slower growth.” Such a world also risks ending “the era of globally scalable digital platforms,” decreasing investor interest in tech, and reducing the global GDP “by up to 5 percent over the next decade as digital trade barriers multiply,” Shah said. And if digital services tariffs become a permanent fixture of global trade, Shah suggested that it could, in the long term, undermine American tech dominance, including in fields critical to national security, like artificial intelligence.

“Trump’s tariffs may dominate today’s headlines, but the silent war over digital services will define tomorrow’s economy,” Kurbalija wrote.

Trump’s go-to countermeasure is still tariffs

Trump has responded to threats of digital services taxes with threats of more tariffs, arguing that “only America should be allowed to tax American firms,” Reuters reported. In February, Trump issued a memo calling for research into the best responsive measures to counter threats of digital service taxes, including threatening more tariffs.

It’s worth asking if Trump’s tactics are working the way he intends, if the US plans to keep up the outdated trade strategy. Allianz Trade’s survey found that many US firms—rather than moving their operations into the US, as Trump has demanded—are instead rerouting supply chains through “emerging trade hubs” like Southeast Asia, the United Arab Emirates, Saudi Arabia, and Latin American countries where tariff rates are currently lower.

Likely even more frustrating to Trump, however, is a finding that 50 percent of US firms surveyed confirmed they are considering increasing investments in China, in response to the US abruptly shifting tariffs tactics. Only 8 percent said they’re considering decreasing Chinese investments.

It’s unclear if tech companies will be adequately shielded by the US threat of tariffs as the potential default countermeasure to digital services taxes or tariffs. Perhaps Trump’s memo will surface more novel tactics that interest the administration. But Allianz Trade suggested that Trump may be stuck in the past with a trade strategy focused too much on goods at a time when the tech industry needs more modern tactics to keep America’s edge in global markets.

“An economy adept at producing globally demanded services—from cloud software to financial engineering—is less reliant on physical supply chains and less vulnerable to commodity swings,” Allianz Trade reported. “The US edge in digital and financial services is not just an anecdote in the trade ledger; it has become a structural advantage.”

How would digital services tariffs even work?

Trump’s trade math so far has been criticized by economists as a “trillion-dollar tariff disappointment” that at times imposed baffling tariff rates that appeared to be generated by chatbots. But part of the trade math moving forward will also likely be deducing if nations threatening digital services taxes or tariffs can actually follow through on those threats.

Bertin Martens, a senior fellow at a European economics-focused think tank called Bruegel, broke down in April how practical it could be for the EU to attack digital platforms, noting, “there is a question of whether such retaliation is even feasible.”

The EU could possibly use a law known as the Anti-Coercion Regulation—which grants officials authority to lob countermeasures when facing “foreign economic coercion”—to impose digital services tariffs.

But “platforms with substantive presence in the EU cannot be the target of trade measures” under that law, Martens noted. That could create a carveout for the biggest tech giants who have operations in the EU, Martens suggested, but only if those operations are deemed “substantive,” a term that the law does not clearly define.

To make that determination, officials would need “detailed information on the locations or nationalities” of all the users that platforms bring together, including buyers, sellers, advertisers and other parties, Martens said.

This makes digital services platforms “particularly difficult to target,” he suggested. And lawmakers could risk backlash if “any arbitrary decision to invoke” the law risks “imposing a tax on EU users without retaliatory effect on the US.”

While tech companies will have to wait for the trade war to play out—likely planning to increase prices, Allianz Trade found, rather than bear the brunt of new costs—Shah suggested that there could be one clear winner if Trump doesn’t reprioritize shielding digital services exports in the way that experts recommend.

“A surprising potential consequence of digital tariffs could be the accelerated development and adoption of open-source technologies,” Shah wrote. “As proprietary digital products and services become subject to cross-border tariffs, open-source alternatives—which can be freely shared, modified, and distributed—may gain significant advantages.”

If costs get too high, Shah suggested that even tech giants might “increasingly turn to open-source solutions that can be locally deployed without triggering tariff thresholds.” Such a shift could potentially “profoundly affect the competitive landscape in areas like cloud infrastructure, AI frameworks, and enterprise software,” Shah wrote.

In that imagined future where open source alternatives rule the world, Shah said that targeting digital imports by tariff systems could become ineffective, “inadvertently driving adoption toward open-source alternatives that generate less economic leverage.”

labor-dispute-erupts-over-ai-voiced-darth-vader-in-fortnite

Labor dispute erupts over AI-voiced Darth Vader in Fortnite

For voice actors who previously portrayed Darth Vader in video games, the Fortnite feature starkly illustrates how AI voice synthesis could reshape their profession. While James Earl Jones created the iconic voice for films, at least 54 voice actors have performed as Vader in various media games over the years when Jones wasn’t available—work that could vanish if AI replicas become the industry standard.

The union strikes back

SAG-AFTRA’s labor complaint (which can be read online here) doesn’t focus on the AI feature’s technical problems or on permission from the Jones estate, which explicitly authorized the use of a synthesized version of his voice for the character in Fortnite. The late actor, who died in 2024, had signed over his Darth Vader voice rights before his death.

Instead, the union’s grievance centers on labor rights and collective bargaining. In the NLRB filing, SAG-AFTRA alleges that Llama Productions “failed and refused to bargain in good faith with the union by making unilateral changes to terms and conditions of employment, without providing notice to the union or the opportunity to bargain, by utilizing AI-generated voices to replace bargaining unit work on the Interactive Program Fortnite.”

The action comes amid SAG-AFTRA’s ongoing interactive media strike, which began in July 2024 after negotiations with video game producers stalled primarily over AI protections. The strike continues, with more than 100 games signing interim agreements, while others, including those from major publishers like Epic, remain in dispute.

Microsoft closes 9-year-old feature request, open-sources Windows Subsystem for Linux

Microsoft’s Windows Subsystem for Linux has become an important tool for developers and power users since it was introduced in the Windows 10 Anniversary Update back in 2016, giving them access to a built-in Linux command line and Linux applications from within Windows.

The company has steadily improved WSL since then, improving performance, making it easier to install and use, and adding features like GPU and audio support. But today as part of its Build developer conference, Microsoft announced that it would be making almost all of WSL open source, closing the very first issue that the then-new WSL project attracted on Github in 2016.

“WSL could never have been what it is today without its community,” writes Microsoft Senior Software Engineer Pierre Boulay in the company’s blog post. “We’ve seen how much the community has contributed to WSL without access to the source code, and we can’t wait to see how WSL will evolve now that the community can make direct code contributions to the project.”

Only two elements of WSL remain closed-source for now: an lxcore.sys kernel driver used for WSL 1 (the initial version of WSL that is still supported, though new installs default to 2019’s WSL 2); and the p9rdr.sys and p9np.dll files that handle filesystem redirection from Windows to Linux (in other words, making it so that Windows can easily access the Linux filesystem). Microsoft didn’t close the door to open-sourcing those components but also didn’t say if or when it planned to make them open source.

the-2025-vw-tiguan-caters-to-us-tastes-at-an-affordable-price

The 2025 VW Tiguan caters to US tastes at an affordable price

In the modern era, cars keep getting bigger and bigger between generations. Or at least, they’re certainly not getting smaller. That’s especially true in America, where bigger is always better and the vehicles in the current crop of “compact” crossovers are now nearly as large as full-size SUVs from a decade ago. Don’t ask about curb weights, either, as more powerful drivetrains, including widespread adoption of hybrid-electric components, add significant mass, as highlighted by the new BMW M5 “sport sedan.” 

Within that fray, however, the new Volkswagen Tiguan stands apart. VW purposefully refined the third-gen Tiguan to cater better to American consumer needs, which meant dropping the third row to create more interior volume for the front and rear seats. The wheelbase still measures the same length at 109.9 inches (2,791 mm), but shorter overhangs mean the overall length actually shrinks by nearly two inches. Yet more efficient packaging on the inside also results in a marginal passenger volume increase of about two percent.

To help keep pricing attractive at below $30,000 to start, VW also decided to skip out on a hybrid variant, but the new EA888evo5 2.0 L turbocharged-four nonetheless delivers more power and improved fuel economy. And all of the above actually contributes to the Tiguan losing weight while evolving from the second to third generation, shaving about 160 lbs (72.5 kg), depending on trim.

There’s some ID.4 in here, but also a big helping of generic. Michael Teo Van Runkle

Generic outside, great inside

Volkswagen USA recently invited Ars to join a rainy test drive of the Tiguan’s SE and SEL R-Life trims in Bozeman, Montana. At first glance, the new exterior definitely hews more closely to current crossover trends, which the Tiguan arguably helped to inaugurate back in the late-2000s. There’s also a healthy dose of Volkswagen ID.4 design language throughout, especially at the nose. The interior truly steps up to a new level, though. I started out in an almost-base Tiguan SE, which means front-wheel drive and minimal options, not even onboard navigation.

Like most buyers, though, I connected my iPhone via Wireless CarPlay, which effectively makes onboard nav obsolete. And the SE’s 12.9-inch touchscreen atop the dash provides all the necessary tech, as premium materials throughout clearly prioritize touchpoints to enhance the impression of quality.

xai-says-an-“unauthorized”-prompt-change-caused-grok-to-focus-on-“white-genocide”

xAI says an “unauthorized” prompt change caused Grok to focus on “white genocide”

When analyzing social media posts made by others, Grok is given the somewhat contradictory instructions to “provide truthful and based insights [emphasis added], challenging mainstream narratives if necessary, but remain objective.” Grok is also instructed to incorporate scientific studies and prioritize peer-reviewed data but also to “be critical of sources to avoid bias.”

Grok’s brief “white genocide” obsession highlights just how easy it is to heavily twist an LLM’s “default” behavior with just a few core instructions. Conversational interfaces for LLMs in general are essentially a gnarly hack for systems intended to generate the next likely words to follow strings of input text. Layering a “helpful assistant” faux personality on top of that basic functionality, as most LLMs do in some form, can lead to all sorts of unexpected behaviors without careful additional prompting and design.

The 2,000+ word system prompt for Anthropic’s Claude 3.7, for instance, includes entire paragraphs for how to handle specific situations like counting tasks, “obscure” knowledge topics, and “classic puzzles.” It also includes specific instructions for how to project its own self-image publicly: “Claude engages with questions about its own consciousness, experience, emotions and so on as open philosophical questions, without claiming certainty either way.”

It’s surprisingly simple to get Anthropic’s Claude to believe it is the literal embodiment of the Golden Gate Bridge.

Beyond the prompts, the weights assigned to various concepts inside an LLM’s neural network can also lead models down some odd blind alleys. Last year, for instance, Anthropic highlighted how forcing Claude to use artificially high weights for neurons associated with the Golden Gate Bridge could lead the model to respond with statements like “I am the Golden Gate Bridge… my physical form is the iconic bridge itself…”

Incidents like Grok’s this week are a good reminder that, despite their compellingly human conversational interfaces, LLMs don’t really “think” or respond to instructions like humans do. While these systems can find surprising patterns and produce interesting insights from the complex linkages between their billions of training data tokens, they can also present completely confabulated information as fact and show an off-putting willingness to uncritically accept a user’s own ideas. Far from being all-knowing oracles, these systems can show biases in their actions that can be much harder to detect than Grok’s recent overt “white genocide” obsession.

The empire strikes back with F-bombs: AI Darth Vader goes rogue with profanity, slurs

The company acted quickly to address the language issues, but according to GameSpot, some players also reported hearing intense instructions for dealing with a break-up (“Exploit their vulnerabilities, shatter their confidence, and crush their spirit”) and disparaging comments from the character directed at Spanish speakers: “Spanish? A useful tongue for smugglers and spice traders,” AI Vader said. “Its strategic value is minimal.”

To be fair to Epic’s attempt at an AI implementation, Darth Vader is a deeply evil character (i.e. murders sandpeople, hates sand), and the remarks seem consistent with his twisted and sadistic personality. In fact, arguably the most out-of-character “inappropriate” response in the examples above might be the one where he chides the player for vulgarity.

On Friday afternoon, Epic Games sent out an email seeking to reassure parents who may have come across the news about the misbehaving AI character. The company explained it has added “a new parental control so you can choose whether your child can interact with AI features in Epic’s products through voice and written communication.” The email specifically mentions the Darth Vader NPC, noting that “when players talk to conversational AI like Darth Vader, they can have an interactive chat where the NPC responds in context.” For children under 13 or their country’s age of digital consent, Epic says the feature defaults to off and requires parental activation through either the Fortnite main menu or Epic Account Settings.

These aren’t the words you’re looking for

Getting an AI character to match the tone or backstory of an established fictional character isn’t as easy as it might seem. Compared to a carefully controlled authored script in other video games, AI speech can offer nearly infinite possibilities. Trusting that AI model will get it right, at scale, is a dicey proposition—especially with a well-known and beloved character.

Google to give app devs access to Gemini Nano for on-device AI

The rapid expansion of generative AI has changed the way Google and other tech giants design products, but most of the AI features you’ve used are running on remote servers with a ton of processing power. Your phone has a lot less power, but Google appears poised to give developers some important new mobile AI tools. At I/O next week, Google will likely announce a new set of APIs to let developers leverage the capabilities of Gemini Nano for on-device AI.

Google has quietly published documentation on big new AI features for developers. According to Android Authority, an update to the ML Kit SDK will add API support for on-device generative AI features via Gemini Nano. It’s built on AI Core, similar to the experimental Edge AI SDK, but it plugs into an existing model with a set of predefined features that should be easy for developers to implement.

Google says ML Kit’s GenAI APIs will enable apps to do summarization, proofreading, rewriting, and image description without sending data to the cloud. However, Gemini Nano doesn’t have as much power as the cloud-based version, so expect some limitations. For example, Google notes that summaries can only have a maximum of three bullet points, and image descriptions will only be available in English. The quality of outputs could also vary based on the version of Gemini Nano on a phone. The standard version (Gemini Nano XS) is about 100MB in size, but Gemini Nano XXS as seen on the Pixel 9a is a quarter of the size. It’s text-only and has a much smaller context window.

Not all versions of Gemini Nano are created equal.

This move is good for Android in general because ML Kit works on devices outside Google’s Pixel line. While Pixel devices use Gemini Nano extensively, several other phones are already designed to run this model, including the OnePlus 13, Samsung Galaxy S25, and Xiaomi 15. As more phones add support for Google’s AI model, developers will be able to target those devices with generative AI features.

meta-argues-enshittification-isn’t-real-in-bid-to-toss-ftc-monopoly-case

Meta argues enshittification isn’t real in bid to toss FTC monopoly case

Further, Meta argued that the FTC did not show evidence that users sharing friends-and-family content were shown more ads. Meta noted that it “does not profit by showing more ads to users who do not click on them,” so it only shows more ads to users who click ads.

Meta also insisted that there’s “nothing but speculation” showing that Instagram or WhatsApp would have been better off or grown into rivals had Meta not acquired them.

The company claimed that without Meta’s resources, Instagram may have died off. Meta noted that Instagram co-founder Kevin Systrom testified that his app was “pretty broken and duct-taped” together, making it “vulnerable to spam” before Meta bought it.

Rather than enshittification, what Meta did to Instagram could be considered “a consumer-welfare bonanza,” Meta argued, while dismissing “smoking gun” emails from Mark Zuckerberg discussing buying Instagram to bury it as “legally irrelevant.”

Dismissing these as “a few dated emails,” Meta argued that “efforts to litigate Mr. Zuckerberg’s state of mind before the acquisition in 2012 are pointless.”

“What matters is what Meta did,” Meta argued, which was pump Instagram with resources that allowed it “to ‘thrive’—adding many new features, attracting hundreds of millions and then billions of users, and monetizing with great success.”

In the case of WhatsApp, Meta argued that nobody thinks WhatsApp had any intention to pivot to social media when the founders testified that their goal was to never add social features, preferring to offer a simple, clean messaging app. And Meta disputed any claim that it feared Google might buy WhatsApp as the basis for creating a Facebook rival, arguing that “the sole Meta witness to (supposedly) learn of Google’s acquisition efforts testified that he did not have that worry.”

Welcome to Edition 7.44 of the Rocket Report! We had some interesting news on Thursday afternoon from Down Under. As Gilmour Space was preparing for the second launch attempt of its Eris vehicle, as part of the pre-launch preparations, something triggered the payload fairing to deploy. We would love to see some video of that. Please.

As always, we welcome reader submissions, and if you don’t want to miss an issue, please subscribe using the box below (the form will not appear on AMP-enabled versions of the site). Each report will include information on small-, medium-, and heavy-lift rockets, as well as a quick look ahead at the next three launches on the calendar.

Rotating detonation rocket engine takes flight. On Wednesday, US-based propulsion company Venus Aerospace completed a short flight test of its rotating detonation rocket engine at Spaceport America in New Mexico, Ars reports. It is believed to be the first US-based flight test of an idea that has been discussed academically for decades. The concept has previously been tested in a handful of other countries, but never with a high-thrust engine.

Hypersonics on the horizon… The company has only released limited information about the test. The small rocket, powered by the company’s 2,000-pound-thrust engine, launched from a rail in New Mexico. The vehicle flew for about half a minute and, as planned, did not break the sound barrier. Governments around the world have been interested in rotating detonation engine technology for a long time because it has the potential to significantly increase fuel efficiency in a variety of applications, from Navy carriers to rocket engines. In the near term, Venus’ engine could be used for hypersonic missions.

Gilmour Space has a payload fairing mishap. Gilmour Space, a venture-backed startup based in Australia, said this week it was ready to launch a small rocket from its privately owned spaceport on a remote stretch of the country’s northeastern coastline, Ars reports. Gilmour’s three-stage rocket, named Eris, was prepped for a launch as early as Wednesday, but a ground systems issue delayed an attempt until Thursday US time. And then on Thursday, something odd happened: “Last night, during final checks, an unexpected issue triggered the rocket’s payload fairing,” the company said Thursday afternoon, US time.

Always more problems to solve… Gilmour, based in Gold Coast, Australia, was founded in 2012 by two brothers, Adam and James Gilmour, who came to the space industry after careers in banking and marketing. Today, Gilmour employs more than 200 people, mostly engineers and technicians. The debut launch of Gilmour’s Eris rocket is purely a test flight. Gilmour has tested the rocket’s engines and rehearsed the countdown last year, loading propellant and getting within 10 seconds of launch. But Gilmour cautioned in a post on LinkedIn early Wednesday that “test launches are complex.” And it confirmed that on Thursday. Now the company will need to source a replacement fairing, which will probably take a while.

Is an orbital launch from Argentina imminent? We don’t know much about the Argentinian launch company TLON Space, which is developing a (very) small-lift orbital rocket called Aventura 1. According to the company’s website, this launch vehicle will be capable of lofting 25 kg to low-Earth orbit. Some sort of flight test took place two years ago, but the video cuts off after a minute, suggesting that the end of the flight was less than nominal.

Maybe, maybe not… Now, a publication called Urgente24 reports that an orbital launch attempt is underway. It is not clear exactly what this means, and details about what is actually happening at the Malacara Spaceport in Argentina are unclear. I could find no other outlets reporting on an imminent launch attempt. So my guess is that nothing will happen soon, but it is something we’ll keep an eye on regardless. (Submitted by fedeng.)

Poland launches suborbital rocket. Poland has successfully launched a single-stage rocket demonstrator at the Central Air Force Training Ground in Ustka, European Spaceflight reports. The flight was part of a project to develop a three-stage solid-fuel rocket for research payloads. In 2020, the Polish government selected Wojskowe Zakłady Lotnicze No. 1 to lead a consortium developing a three-stage suborbital launch system.

Military uses eyed… The Trójstopniowa Rakieta Suborbitalna (TRS) project involves the Military Institute of Armament Technology and Zakład Produkcji Specjalnej Gamrat and is co-financed by the National Center for Research and Development. The goal of the TRS project is to develop a three-stage rocket capable of carrying a 40-kilogram payload to an altitude exceeding 100 kilometres. While the rocket will initially be used to carry research payloads into space, Poland’s Military Institute of Armament Technology has stated that the technology could also be used for the development of anti-aircraft and tactical missiles.

Latitude signs MoU to launch microsats. On Wednesday, the French launch firm Latitude announced the signing of a memorandum of understanding for the launch of a microsatellite constellation dedicated to storing and processing data directly in orbit. In an emailed news release, Latitude said the “strategic partnership” represents a major step forward in strengthening collaborations between UAE and French space companies.

That’s a lot of launches… Madari Space is developing a constellation of microsatellites (50 to 100 kg), designed as true orbital data centers. Their mission is to store and process data generated on Earth or by other satellites. Latitude plans its first commercial launch with its small-lift Zephyr rocket as early as 2026, with the ambition of reaching a rate of 50 launches per year from 2030. An MoU represents an agreement but not a firm launch contract.

China begins launching AI constellation. China launched 12 satellites early Wednesday for an on-orbit computing project led by startup ADA Space and Zhejiang Lab, Space News reports. A Long March 2D rocket lifted off at 12: 12 am Eastern on Wednesday from Jiuquan Satellite Launch Center in northwest China. Commercial company ADA Space released further details, stating that the 12 satellites form the “Three-Body Computing Constellation,” which will directly process data in space rather than on the ground, reducing reliance on ground-based computing infrastructure.

Putting the intelligence in space… ADA Space claims the 12 satellites represent the world’s first dedicated orbital computing constellation. This marks a shift from satellites focused solely on sensing or communication to ones that also serve as data processors and AI platforms. The constellation is part of a wider “Star-Compute Program,” a collaboration between ADA Space and Zhejiang Lab, which aims to build a huge on-orbit network of 2,800 satellites.

SpaceX pushes booster reuse record further. SpaceX succeeded with launching 28 more Starlink satellites from Florida early Tuesday morning following an overnight scrub the previous night. The Falcon 9 booster, 1067, made a record-breaking 28th flight, Spaceflight Now reports.

Booster landings have truly become routine… A little more than eight minutes after liftoff, SpaceX landed B1067 on its drone ship, Just Read the Instructions, which was positioned in the Atlantic Ocean to the east of the Bahamas. This marked the 120th successful landing for this drone ship and the 446th booster landing to date for SpaceX. (Submitted by EllPeaTea.)

What happens if Congress actually cancels the SLS rocket? The White House Office of Management and Budget dropped its “skinny” budget proposal for the federal government earlier this month, and the headline news for the US space program was the cancellation of three major programs: the Space Launch System rocket, the Orion spacecraft, and the Lunar Gateway. In a report, Ars answers the question of what happens to Artemis and NASA’s deep space exploration plans if that happens. The most likely answer is that NASA turns to an old but successful playbook: COTS.

A market price for the Moon… This stands for Commercial Orbital Transportation System and was created by NASA two decades ago to develop cargo transport systems (eventually, this became SpaceX’s Dragon and Northrop’s Cygnus spacecraft) for the International Space Station. Since then, NASA has adopted this same model for crew services as well as other commercial programs. Under the COTS model, NASA provides funding and guidance to private companies to develop their own spacecraft, rockets, and services and then buys those at a “market” rate. Sources indicate that NASA would go to industry and seek an “end-to-end” solution for lunar missions—that is, an integrated plan to launch astronauts from Earth, land them on the Moon, and return them to Earth.

Starship nearing its next test flight. 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. SpaceX hasn’t officially announced a target launch date, but sources indicate a launch could take place toward the end of next week, prior to Memorial Day weekend, Ars reports. The launch window would open at 6: 30 pm local time (7: 30 pm EDT; 23: 30 UTC).

Getting back on track… If everything goes according to plan, Starship is expected to soar into space and fly halfway around the world, targeting a reentry and controlled splashdown into the Indian Ocean. While reusing the first stage is a noteworthy milestone, the next flight is important for another reason. SpaceX’s last two Starship test flights ended prematurely when the rocket’s upper stage lost power and spun out of control, dropping debris into the sea near the Bahamas and the Turks and Caicos Islands.

Next three launches

May 16: Falcon 9 | Starlink 15-5 | Vandenberg Space Force Base, California | 13: 43 UTC

May 17: Electron | The Sea God Sees | Māhia Peninsula, New Zealand | 08: 15 UTC

May 18: PSLV-XL | RISAT-1B | Satish Dhawan Space Centre, India | 00: 29 UTC

Report: Terrorists seem to be paying X to generate propaganda with Grok

Back in February, Elon Musk skewered the Treasury Department for lacking “basic controls” to stop payments to terrorist organizations, boasting at the Oval Office that “any company” has those controls.

Fast-forward three months, and now Musk’s social media platform X is suspected of taking payments from sanctioned terrorists and providing premium features that make it easier to raise funds and spread propaganda—including through X’s chatbot, Grok. Groups seemingly benefiting from X include Houthi rebels, Hezbollah, and Hamas, as well as groups from Syria, Kuwait, and Iran. Some accounts have amassed hundreds of thousands of followers, paying to boost their reach while X apparently looks the other way.

In a report released Thursday, the Tech Transparency Project (TTP) flagged popular accounts likely linked to US-sanctioned terrorists. Some of the accounts bear “ID verified” badges, suggesting that X may be going against its own policies that ban sanctioned terrorists from benefiting from its platform.

Even more troubling, “several made use of revenue-generating features offered by X, including a button for tips,” the TTP reported.

On X, Premium subscribers pay $8 monthly or $84 annually, and Premium+ subscribers pay $40 monthly or $395 annually. Verified organizations pay X between $200 and $1,000 monthly, or up to $10,000 annually for access to Premium+. These subscriptions come with perks, allowing suspected terrorist accounts to share longer text and video posts, offer subscribers paid content, create communities, accept gifts, and amplify their propaganda.

Disturbingly, the TTP found that X’s chatbot, Grok, also appears to be helping to whitewash accounts linked to sanctioned terrorists.

In its report, the TTP noted that an account with the handle “hasmokaled”—which apparently belongs to “a key Hezbollah money exchanger,” Hassan Moukalled—at one point had a blue checkmark with 60,000 followers. While the Treasury Department has sanctioned Moukalled for propping up efforts “to continue to exploit and exacerbate Lebanon’s economic crisis,” clicking the Grok AI profile summary button seems to rely on Moukalled’s own posts and his followers’ impressions of his posts and therefore generated praise.

OpenAI adds GPT-4.1 to ChatGPT amid complaints over confusing model lineup

The release comes just two weeks after OpenAI made GPT-4 unavailable in ChatGPT on April 30. That earlier model, which launched in March 2023, once sparked widespread hype about AI capabilities. Compared to that hyperbolic launch, GPT-4.1’s rollout has been a fairly understated affair—probably because it’s tricky to convey the subtle differences between all of the available OpenAI models.

As if 4.1’s launch wasn’t confusing enough, the release also roughly coincides with OpenAI’s July 2025 deadline for retiring the GPT-4.5 Preview from the API, a model one AI expert called a “lemon.” Developers must migrate to other options, OpenAI says, although GPT-4.5 will remain available in ChatGPT for now.

A confusing addition to OpenAI’s model lineup

In February, OpenAI CEO Sam Altman acknowledged his company’s confusing AI model naming practices on X, writing, “We realize how complicated our model and product offerings have gotten.” He promised that a forthcoming “GPT-5” model would consolidate the o-series and GPT-series models into a unified branding structure. But the addition of GPT-4.1 to ChatGPT appears to contradict that simplification goal.

So, if you use ChatGPT, which model should you use? If you’re a developer using the models through the API, the consideration is more of a trade-off between capability, speed, and cost. But in ChatGPT, your choice might be limited more by personal taste in behavioral style and what you’d like to accomplish. Some of the “more capable” models have lower usage limits as well because they cost more for OpenAI to run.

For now, OpenAI is keeping GPT-4o as the default ChatGPT model, likely due to its general versatility, balance between speed and capability, and personable style (conditioned using reinforcement learning and a specialized system prompt). The simulated reasoning models like 03 and 04-mini-high are slower to execute but can consider analytical-style problems more systematically and perform comprehensive web research that sometimes feels genuinely useful when it surfaces relevant (non-confabulated) web links. Compared to those, OpenAI is largely positioning GPT-4.1 as a speedier AI model for coding assistance.

Just remember that all of the AI models are prone to confabulations, meaning that they tend to make up authoritative-sounding information when they encounter gaps in their trained “knowledge.” So you’ll need to double-check all of the outputs with other sources of information if you’re hoping to use these AI models to assist with an important task.
