Abuse allows Meta and Yandex to attach persistent identifiers to detailed browsing histories.

Tracking code that Meta and Russia-based Yandex embed into millions of websites is de-anonymizing visitors by abusing legitimate Internet protocols, causing Chrome and other browsers to surreptitiously send unique identifiers to native apps installed on a device, researchers have discovered. Google says it’s investigating the abuse, which allows Meta and Yandex to convert ephemeral web identifiers into persistent mobile app user identities.

The covert tracking—implemented in the Meta Pixel and Yandex Metrica trackers—allows Meta and Yandex to bypass core security and privacy protections provided by both the Android operating system and browsers that run on it. Android sandboxing, for instance, isolates processes to prevent them from interacting with the OS and any other app installed on the device, cutting off access to sensitive data or privileged system resources. Defenses such as state partitioning and storage partitioning, which are built into all major browsers, store site cookies and other data associated with a website in containers that are unique to every top-level website domain to ensure they’re off-limits for every other site.

A blatant violation

“One of the fundamental security principles that exists in the web, as well as the mobile system, is called sandboxing,” Narseo Vallina-Rodriguez, one of the researchers behind the discovery, said in an interview. “You run everything in a sandbox, and there is no interaction within different elements running on it. What this attack vector allows is to break the sandbox that exists between the mobile context and the web context. The channel that exists allowed the Android system to communicate what happens in the browser with the identity running in the mobile app.”

The bypass—which Yandex began in 2017 and Meta started last September—allows the companies to pass cookies or other identifiers from Firefox and Chromium-based browsers to native Android apps for Facebook, Instagram, and various Yandex apps. The companies can then tie that vast browsing history to the account holder logged into the app.

This abuse has been observed only in Android, and evidence suggests that the Meta Pixel and Yandex Metrica target only Android users. The researchers say it may be technically feasible to target iOS because browsers on that platform allow developers to programmatically establish localhost connections that apps can monitor on local ports.

In contrast to iOS, however, Android imposes fewer controls on local host communications and background executions of mobile apps, the researchers said, while also implementing stricter controls in app store vetting processes to limit such abuses. This overly permissive design allows Meta Pixel and Yandex Metrica to send web requests with web tracking identifiers to specific local ports that are continuously monitored by the Facebook, Instagram, and Yandex apps. These apps can then link pseudonymous web identities with actual user identities, even in private browsing modes, effectively de-anonymizing users’ browsing habits on sites containing these trackers.

Meta Pixel and Yandex Metrica are analytics scripts designed to help advertisers measure the effectiveness of their campaigns. Meta Pixel and Yandex Metrica are estimated to be installed on 5.8 million and 3 million sites, respectively.

Meta and Yandex achieve the bypass by abusing basic functionality built into modern mobile browsers that allows browser-to-native app communications. The functionality lets browsers send web requests to local Android ports to establish various services, including media connections through the RTC protocol, file sharing, and developer debugging.

While the technical underpinnings differ, both Meta Pixel and Yandex Metrica are performing a “weird protocol misuse” to gain unvetted access that Android provides to localhost ports on the 127.0.0.1 IP address. Browsers access these ports without user notification. Facebook, Instagram, and Yandex native apps silently listen on those ports, copy identifiers in real time, and link them to the user logged into the app.

A representative for Google said the behavior violates the terms of service for its Play marketplace and the privacy expectations of Android users.

“The developers in this report are using capabilities present in many browsers across iOS and Android in unintended ways that blatantly violate our security and privacy principles,” the representative said, referring to the people who write the Meta Pixel and Yandex Metrica JavaScript. “We’ve already implemented changes to mitigate these invasive techniques and have opened our own investigation and are directly in touch with the parties.”

Meta didn’t answer emailed questions for this article, but provided the following statement: “We are in discussions with Google to address a potential miscommunication regarding the application of their policies. Upon becoming aware of the concerns, we decided to pause the feature while we work with Google to resolve the issue.”

Yandex representatives didn’t answer an email seeking comment.

How Meta and Yandex de-anonymize Android users

Meta Pixel developers have abused various protocols to implement the covert listening since the practice began last September. They started by causing apps to send HTTP requests to port 12387. A month later, Meta Pixel stopped sending this data, even though Facebook and Instagram apps continued to monitor the port.

In November, Meta Pixel switched to a new method that invoked WebSocket, a protocol for two-way communications, over port 12387.

That same month, Meta Pixel also deployed a new method that used WebRTC, a real-time peer-to-peer communication protocol commonly used for making audio or video calls in the browser. This method used a complicated process known as SDP munging, a technique for JavaScript code to modify Session Description Protocol data before it’s sent. Still in use today, the SDP munging by Meta Pixel inserts key _fbp cookie content into fields meant for connection information. This causes the browser to send that data as part of a STUN request to the Android local host, where the Facebook or Instagram app can read it and link it to the user.

In May, a beta version of Chrome introduced a mitigation that blocked the type of SDP munging that Meta Pixel used. Within days, Meta Pixel circumvented the mitigation by adding a new method that swapped the STUN requests with the TURN requests.

In a post, the researchers provided a detailed description of the _fbp cookie from a website to the native app and, from there, to the Meta server:

1. The user opens the native Facebook or Instagram app, which eventually is sent to the background and creates a background service to listen for incoming traffic on a TCP port (12387 or 12388) and a UDP port (the first unoccupied port in 12580–12585). Users must be logged-in with their credentials on the apps.

2. The user opens their browser and visits a website integrating the Meta Pixel.

3. At this stage, some websites wait for users’ consent before embedding Meta Pixel. In our measurements of the top 100K website homepages, we found websites that require consent to be a minority (more than 75% of affected sites does not require user consent)…

4. The Meta Pixel script is loaded and the _fbp cookie is sent to the native Instagram or Facebook app via WebRTC (STUN) SDP Munging.

5. The Meta Pixel script also sends the _fbp value in a request to https://www.facebook.com/tr along with other parameters such as page URL (dl), website and browser metadata, and the event type (ev) (e.g., PageView, AddToCart, Donate, Purchase).

6. The Facebook or Instagram apps receive the _fbp cookie from the Meta JavaScripts running on the browser and transmits it to the GraphQL endpoint (https://graph[.]facebook[.]com/graphql) along with other persistent user identifiers, linking users’ fbp ID (web visit) with their Facebook or Instagram account.

Detailed flow of the way the Meta Pixel leaks the _fbp cookie from Android browsers to it’s Facebook and Instagram apps.

The first known instance of Yandex Metrica linking websites visited in Android browsers to app identities was in May 2017, when the tracker started sending HTTP requests to local ports 29009 and 30102. In May 2018, Yandex Metrica also began sending the data through HTTPS to ports 29010 and 30103. Both methods remained in place as of publication time.

An overview of Yandex identifier sharing

A timeline of web history tracking by Meta and Yandex

Some browsers for Android have blocked the abusive JavaScript in trackers. DuckDuckGo, for instance, was already blocking domains and IP addresses associated with the trackers, preventing the browser from sending any identifiers to Meta. The browser also blocked most of the domains associated with Yandex Metrica. After the researchers notified DuckDuckGo of the incomplete blacklist, developers added the missing addresses.

The Brave browser, meanwhile, also blocked the sharing of identifiers due to its extensive blocklists and existing mitigation to block requests to the localhost without explicit user consent. Vivaldi, another Chromium-based browser, forwards the identifiers to local Android ports when the default privacy setting is in place. Changing the setting to block trackers appears to thwart browsing history leakage, the researchers said.

There’s got to be a better way

The various remedies DuckDuckGo, Brave, Vivaldi, and Chrome have put in place are working as intended, but the researchers caution they could become ineffective at any time.

“Any browser doing blocklisting will likely enter into a constant arms race, and it’s just a partial solution,” Vallina Rodriguez said of the current mitigations. “Creating effective blocklists is hard, and browser makers will need to constantly monitor the use of this type of capability to detect other hostnames potentially abusing localhost channels and then updating their blocklists accordingly.”

He continued:

While this solution works once you know the hostnames doing that, it’s not the right way of mitigating this issue, as trackers may find ways of accessing this capability (e.g., through more ephemeral hostnames). A long-term solution should go through the design and development of privacy and security controls for localhost channels, so that users can be aware of this type of communication and potentially enforce some control or limit this use (e.g., a permission or some similar user notifications).

Chrome and most other Chromium-based browsers executed the JavaScript as Meta and Yandex intended. Firefox did as well, although for reasons that aren’t clear, the browser was not able to successfully perform the SDP munging specified in later versions of the code. After blocking the STUN variant of SDP munging in the early May beta release, a production version of Chrome released two weeks ago began blocking both the STUN and TURN variants. Other Chromium-based browsers are likely to implement it in the coming weeks. Firefox didn’t respond to an email asking if it has plans to block the behavior in that browser.

The researchers warn that the current fixes are so specific to the code in the Meta and Yandex trackers that it would be easy to bypass them with a simple update.

“They know that if someone else comes in and tries a different port number, they may bypass this protection,” said Gunes Acar, the researcher behind the initial discovery, referring to the Chrome developer team at Google. “But our understanding is they want to send this message that they will not tolerate this form of abuse.”

Fellow researcher Vallina-Rodriguez said the more comprehensive way to prevent the abuse is for Android to overhaul the way it handles access to local ports.

“The fundamental issue is that the access to the local host sockets is completely uncontrolled on Android,” he explained. “There’s no way for users to prevent this kind of communication on their devices. Because of the dynamic nature of JavaScript code and the difficulty to keep blocklists up to date, the right way of blocking this persistently is by limiting this type of access at the mobile platform and browser level, including stricter platform policies to limit abuse.”

Got consent?

The researchers who made this discovery are:

Aniketh Girish, PhD student at IMDEA Networks
Gunes Acar, assistant professor in Radboud University’s Digital Security Group & iHub
Narseo Vallina-Rodriguez, associate professor at IMDEA Networks
Nipuna Weerasekara, PhD student at IMDEA Networks
Tim Vlummens, PhD student at COSIC, KU Leuven

Acar said he first noticed Meta Pixel accessing local ports while visiting his own university’s website.

There’s no indication that Meta or Yandex has disclosed the tracking to either websites hosting the trackers or end users who visit those sites. Developer forums show that many websites using Meta Pixel were caught off guard when the scripts began connecting to local ports.

“Since 5th September, our internal JS error tracking has been flagging failed fetch requests to localhost: 12387,” one developer wrote. “No changes have been made on our side, and the existing Facebook tracking pixel we use loads via Google Tag Manager.”

“Is there some way I can disable this?” another developer encountering the unexplained local port access asked.

It’s unclear whether browser-to-native-app tracking violates any privacy laws in various countries. Both Meta and companies hosting its Meta Pixel, however, have faced a raft of lawsuits in recent years alleging that the data collected violates privacy statutes. A research paper from 2023 found that Meta pixel, then called the Facebook Pixel, “tracks a wide range of user activities on websites with alarming detail, especially on websites classified as sensitive categories under GDPR,” the abbreviation for the European Union’s General Data Protection Regulation.

So far, Google has provided no indication that it plans to redesign the way Android handles local port access. For now, the most comprehensive protection against Meta Pixel and Yandex Metrica tracking is to refrain from installing the Facebook, Instagram, or Yandex apps on Android devices.

Netflix held its Tudum Global Fan Event in Los Angeles this weekend to showcase its upcoming slate of programming. Among the highlights: the official trailer for the third and final season of Squid Game, the first six minutes of Wednesday S2, a teaser for Guillermo del Toro’s Frankenstein, and date announcements for the fifth and final season of Stranger Things, as well as Wake Up Dead Man: A Knives Out Mystery.

(Some spoilers below.)

Squid Game S3

As previously reported, Squid Game‘s first season followed Seong Gi-hun (Lee Jung-Jae), a down-on-his-luck gambler who has little left to lose when he agrees to play children’s playground games against 455 other players for money. The twist? If you lose a game, you die. If you cheat, you die. And if you win, you might also die. In the S1 finale, Gi-hun faced off against fellow finalist and childhood friend Cho Sang-woo (Park Hae-soo) in the titular “squid game.” He won their fight but refused to kill his friend. Sang-woo instead stabbed himself in the neck, leaving Gi-hun the guilt-ridden winner.

S2 was set three years later. Gi-hun successfully finagled his way back into the game, intent on revenge against the Front Man (Lee Byung-hun). Meanwhile, Front Man’s police officer brother, Jun-ho (Wi Ha-joon), hired mercenaries to track down the island where the game is staged. Alliances formed and shifted as the games proceeded, with betrayals galore, culminating in the loss of Gi-hun’s friend and ally Player 390 and a cliffhanger ending.

Series creator Hwang Dong-hyuk conceived of S2 and S3 as a single season, but there were too many episodes, so he split them over two seasons. Back in January we got our first glimpse of S3 when Netflix released a 15-second teaser on X, introducing a brand-new killer doll dubbed Chul-su—similar to the giant “Red Light, Green Light” doll Young-hee. Per the official premise:

A failed rebellion, the death of a friend, and a secret betrayal. Picking up in the aftermath of Season 2’s bloody cliffhanger, the third and final season of Netflix’s most popular series finds Gi-hun, a.k.a. Player 456, at his lowest point yet. But the Squid Game stops for no one, so Gi-hun will be forced to make some important choices in the face of overwhelming despair as he and the surviving players are thrust into deadlier games that test everyone’s resolve. With each round, their choices lead to increasingly grave consequences. Meanwhile, In-ho resumes his role as Front Man to welcome the mysterious VIPs, and his brother Jun-ho continues his search for the elusive island, unaware there’s a traitor in their midst. Will Gi-hun make the right decisions, or will Front Man finally break his spirit?

The third season of Squid Game drops on Netflix on June 27, 2025.

Wednesday S2

Star Jenna Ortega put her own stamp on the iconic title character in the first season of Wednesday. At Tudum, Netflix introduced footage of S2’s first six minutes with a performance by Lady Gaga, who emerged from a coffin to perform a couple of spooky numbers—including “Bloody Mary” from Born This Way. (We can thank a viral video featuring the tune set to Wednesday’s fantastic S1 dancing sequence for that.)

As previously reported, along with Ortega, most of the main cast is returning for S2, including Emma Myers as Enid, and Joy Sunday as Bianca. Reprising their roles: Luis Guzman and Catherine Zeta-Jones as Gomez and Morticia Addams; Isaac Ordonez as Pugsley Addams; Victor Dorobantu as Thing; Fred Armisen as Uncle Fester; Luyanda Unati Lewis-Nyawo as Deputy Ritchie Santiago; Hunter Doohan as Tyler Galpin, revealed as a murderous Hyde in the S1 finale; and Jamie McShane as Donovan Galpin, the Jericho sheriff and Tyler’s father (McShane is a guest this season).

We’ll miss Gwendoline Christie’s Principal Larissa Weems and Christina Ricci’s diabolical botany teacher, Marilyn Thornhill (RIP to both), but at least we’re getting the fabulous Joanna Lumley as Hester Frump, Morticia’s mother. Other new cast members include Billie Piper as Capri, Steve Buscemi as new Nevermore principle Barry Dort, and Evie Templeton, Owen Painter, and Noah Tyler in as-yet-undisclosed roles. Bonus: Lady Gaga will make a guest appearance in the show, and, as we see in the new footage, Haley Joel Osment makes a cameo.

Wednesday S2 will air in two installments. Part 1 debuts August 6, 2025. Part 2 is coming on September 3, 2025.

Stranger Things S5

It’s been a long, wild ride with the plucky residents of Hawkins, but we’re finally approaching the ultimate showdown against the dark force that has plagued the town since S1. The fifth season will have eight episodes and each one will be looong—akin to eight feature-length films.

In addition to the returning main cast, Amybeth McNulty and Gabriella Pizzolo are back as Vicki and Dustin’s girlfriend, Suzie, respectively, with Jamie Campbell Bower reprising his role as the ultimate Big Bad, now known as Vecna. Linda Hamilton joins the cast as Dr. Kay, along with Nell Fisher as Holly Wheeler, Jake Connelly as Derek Turnbow, and Alex Breaux as Lt. Akers

S4 ended with Vecna opening the gate that allowed the Upside Down to leak into Hawkins. We’re getting a time jump for S5, but in a way we’re coming full circle, since the events coincide with the third anniversary of Will’s original disappearance in S1. Per the official premise:

The fall of 1987. Hawkins is scarred by the opening of the Rifts, and our heroes are united by a single goal: find and kill Vecna. But he has vanished—his whereabouts and plans unknown. Complicating their mission, the government has placed the town under military quarantine and intensified its hunt for Eleven, forcing her back into hiding. As the anniversary of Will’s disappearance approaches, so does a heavy, familiar dread. The final battle is looming—and with it, a darkness more powerful and more deadly than anything they’ve faced before. To end this nightmare, they’ll need everyone—the full party—standing together, one last time.

The fifth and final season of Stranger Things will drop in not one, not two, but three installments, because apparently Netflix wants to be as annoying as possible. Volume 1 premieres on November 26, 2025; Volume 2 drops on Christmas Day, December 25, 2025; and the series finale will air on New Year’s Eve, December 31, 2025.

Frankenstein

Oscar-wining director Guillermo del Toro has been dreaming of adapting Mary Shelley’s Frankenstein for the big screen for more than a decade. There have been so many adaptations of Shelley’s novel, of varying quality, and even more reinventions and homages (cf. Poor Things). We finally have the first teaser for del Toro’s take, and it’s as sumptuously horrifying and visually rich as one would expect from the man who made such films as Pan’s Labyrinth and The Shape of Water.

Per the official premise: “A brilliant but egotistical scientist brings a creature to life in a monstrous experiment that ultimately leads to the undoing of both the creator and his tragic creation.” The events take place in 19th century Eastern Europe. Oscar Isaac stars as Victor Frankenstein, with Jacob Elordi playing the monster. Christopher Waltz plays Dr. Pretorious, who hopes to continue in Victor’s footsteps by tracking his monster—who, it turns out, did not die in a fire 40 years before.

The cast also includes Mia Goth as Victor’s fiancee, Elizabeth; Felix Kammerer as Williams; Lars Mikkelsen as Captain Anderson; David Bradley as a blind man; and Ralph Inseon as Professor Kempre. Charles Dance will also appear in an as-yet-undisclosed role.

Frankenstein premieres on Netflix in November 2025.

Wake Up Dead Man: A Knives Out Mystery

Rian Johnson’s Knives Out series of films is still going strong, with the third installment featuring Daniel Craig’s languorously brilliant detective, Benoit Blanc, slated to premiere a couple of weeks before Christmas. It’s called Wake Up Dead Man, a title that pays homage to the 1997 U2 song of the same name.

Johnson is playing his cards close to the chest about the plot details. But we do know he’s assembled another all-star cast of murderous suspects: Josh O’Connor, Glenn Close, Josh Brolin, Mila Kunis, Jeremy Renner—whose “Renning Hot” chili pepper sauce featured prominently in Glass Onion—Kerry Washington, Andrew Scott, Cailee Spaeny, Daryl McCormack, and Thomas Haden Church.

Wake Up Dead Man: A Knives Out Mystery drops on Netflix on December 12, 2025—or if you want to be all Benoit Blanc about it, XII.XII.MMXXV.

Trump pulls Isaacman nomination for space. Source: “NASA is f***ed”

isaacman, NASA, Space, Trump / Rejus Almole / June 1, 2025

Musk was a key factor behind Isaacman’s nomination as NASA administrator, and with his backing, Isaacman was able to skip some of the party purity tests that have been applied to other Trump administration nominees. One mark against Isaacman is that he had recently donated money to Democrats. He also indicated opposition to some of the White House’s proposed cuts to NASA’s science budget.

Musk’s role in the government was highly controversial, winning him enemies both among opponents of Trump’s “Make America Great Again” agenda as well as inside the administration. One source told Ars that, with Musk’s exit, his opponents within the administration sought to punish him by killing Isaacman’s nomination.

The loss of Isaacman is almost certainly a blow to NASA, which faces substantial budget cuts. The Trump Administration’s budget request for fiscal year 2026, released Friday, seeks $18.8 billion for the agency next year—a 24 percent cut from the agency’s budget of $24.8 billion for FY 2025.

Going out of business?

Isaacman is generally well-liked in the space community and is known to care deeply about space exploration. Officials within the space agency—and the larger space community—hoped that having him as NASA’s leader would help the agency restore some of these cuts.

Now? “NASA is f—ed,” one current leader in the agency told Ars on Saturday.

“NASA’s budget request is just a going-out-of-business mode without Jared there to innovate,” a former senior NASA leader said.

The Trump administration did not immediately name a new nominee, but two people told Ars that former US Air Force Lieutenant General Steven L. Kwast may be near the top of the list. Now retired, Kwast has a distinguished record in the Air Force and is politically loyal to Trump and MAGA.

However, his background seems to be far less oriented toward NASA’s civil space mission and far more focused on seeing space as a battlefield—decidedly not an arena for cooperation and peaceful exploration.

After Supreme Court loss, ISPs ask Trump admin to block state affordability laws

broadband lobby, Policy, state broadband laws / Rejus Almole / June 1, 2025

A California bill would require $15 plans with download speeds of 100Mbps and upload speeds of 20Mbps. The broadband lobby groups’ filing said ISPs are also worried about “unnecessary anticompetitive regulations” proposed in Connecticut, Hawaii, Maine, Maryland, Massachusetts, Minnesota, Pennsylvania, Rhode Island, Vermont, and West Virginia.

Not all the pending state bills are specifically about prices charged to low-income users. Some would impose net neutrality requirements or classify ISPs as utilities, the filing said.

Preempting state laws while simultaneously avoiding federal regulation has been a long-held dream for the broadband industry. During the first Trump administration, then-FCC Chairman Ajit Pai led a vote to eliminate the FCC’s net neutrality rules and preempt all 50 states from passing their own net neutrality laws. But the FCC’s broad preemption attempt failed in court.

When challenging the New York affordability mandate, ISPs claimed the state law was preempted by the Pai FCC’s decision to deregulate broadband. But this argument failed for the same reason that Pai’s earlier preemption attempt failed—the FCC decision to deregulate removed the FCC’s strongest regulatory authority over broadband, and courts have ruled that the FCC cannot preempt state laws in an area that it is not regulating.

The Pai FCC’s “order stripped the agency of its authority to regulate the rates charged for broadband Internet, and a federal agency cannot exclude states from regulating in an area where the agency itself lacks regulatory authority,” the US Court of Appeals for the 2nd Circuit said in the ruling that upheld New York’s law last year.

ISPs keep making same argument

ISPs still aren’t giving up on the argument, as they hope a court might someday rule differently. The lobby groups’ filing reminded the Department of Justice that during the first Trump administration, the government brought a preemption suit against California’s net neutrality law.

“The Department unfortunately dropped out of the litigation after the change in Administration,” the filing said. “But as then-Attorney General [Jeff] Sessions explained in initiating the action, California had ‘enacted an extreme and illegal state law attempting to frustrate [the] federal policy’ of an unfettered market for broadband, and the Justice Department had a ‘duty to defend the prerogatives of the federal government and protect our Constitutional order.'”

The Gmail app will now create AI summaries whether you want them or not

AI, Artificial Intelligence, Gmail, Google, Tech / Rejus Almole / June 1, 2025

Gmail AI summary — This block of AI-generated text will soon appear automatically in some threads. Credit: Google

Summarizing content is one of the more judicious applications of generative AI technology, dating back to the 2017 paper on the transformer architecture. Generative AI has since been employed to create chatbots that will seemingly answer any question, despite their tendency to make mistakes. Grounding the AI output with a few emails usually yields accurate results, but do you really need a robot to summarize your emails? Unless you’re getting novels in your inbox, you can probably just read a few paragraphs.

If you’re certain you don’t want any part of this, there is a solution. Automatic generation of AI summaries is controlled by Gmail’s “smart features.” You (or an administrator of your managed account) can disable that. Open the app settings, select the account, and uncheck the smart features toggle.

For most people, Gmail’s smart features are enabled out of the box, but they’re off by default in Europe and Japan. When you disable them, you won’t see the automatic AI summaries, but there will still be a button to generate those summaries with Gemini. Be aware that smart features also control high-priority notifications, package tracking, Smart Compose, Smart Reply, and nudges. If you can live without all of those features in the mobile app, you can avoid automatic AI summaries. The app will occasionally pester you to turn smart features back on, though.

Real TikTokers are pretending to be Veo 3 AI creations for fun, attention

AI, tiktok, Veo 3 / Rejus Almole / May 31, 2025

The turing test in reverse

From music videos to “Are you a prompt?” stunts, “real” videos are presenting as AI

Of course I’m an AI creation! Why would you even doubt it? Credit: Getty Images

Since Google released its Veo 3 AI model last week, social media users have been having fun with its ability to quickly generate highly realistic eight-second clips complete with sound and lip-synced dialogue. TikTok’s algorithm has been serving me plenty of Veo-generated videos featuring impossible challenges, fake news reports, and even surreal short narrative films, to name just a few popular archetypes.

However, among all the AI-generated video experiments spreading around, I’ve also noticed a surprising counter-trend on my TikTok feed. Amid all the videos of Veo-generated avatars pretending to be real people, there are now also a bunch of videos of real people pretending to be Veo-generated avatars.

“This has to be real. There’s no way it’s AI.”

I stumbled on this trend when the TikTok algorithm fed me this video topped with the extra-large caption “Google VEO 3 THIS IS 100% AI.” As I watched and listened to the purported AI-generated band that appeared to be playing in the crowded corner of someone’s living room, I read the caption containing the supposed prompt that had generated the clip: “a band of brothers with beards playing rock music in 6/8 with an accordion.”

@kongosmusicWe are so cooked. This took 3 mins to generate. Simple prompt: “a band of brothers playing rock music in 6/8 with an accordion”♬ original sound – KONGOS

After a few seconds of taking those captions at face value, something started to feel a little off. After a few more seconds, I finally noticed the video was posted by Kongos, an indie band that you might recognize from their minor 2012 hit “Come With Me Now.” And after a little digging, I discovered the band in the video was actually just Kongos, and the tune was a 9-year-old song that the band had dressed up as an AI creation to get attention.

Here’s the sad thing: It worked! Without the “Look what Veo 3 did!” hook, I might have quickly scrolled by this video before I took the time to listen to the (pretty good!) song. The novel AI angle made me stop just long enough to pay attention to a Kongos song for the first time in over a decade.

Kongos isn’t the only musical act trying to grab attention by claiming their real performances are AI creations. Darden Bela posted that Veo 3 had “created a realistic AI music video” over a clip from what is actually a 2-year-old music video with some unremarkable special effects. Rapper GameBoi Pat dressed up an 11-month-old song with a new TikTok clip captioned “Google’s Veo 3 created a realistic sounding rapper… This has to be real. There’s no way it’s AI” (that last part is true, at least). I could go on, but you get the idea.

@gameboi_pat This has got to be real. There’s no way it’s AI 😩 #google #veo3 #googleveo3 #AI #prompts #areweprompts? ♬ original sound – GameBoi_pat

I know it’s tough to get noticed on TikTok, and that creators will go to great lengths to gain attention from the fickle algorithm. Still, there’s something more than a little off-putting about flesh-and-blood musicians pretending to be AI creations just to make social media users pause their scrolling for a few extra seconds before they catch on to the joke (or don’t, based on some of the comments).

The whole thing evokes last year’s stunt where a couple of podcast hosts released a posthumous “AI-generated” George Carlin routine before admitting that it had been written by a human after legal threats started flying. As an attention-grabbing stunt, the conceit still works. You want AI-generated content? I can pretend to be that!

Are we just prompts?

Some of the most existentially troubling Veo-generated videos floating around TikTok these days center around a gag known as “the prompt theory.” These clips focus on various AI-generated people reacting to the idea that they are “just prompts” with various levels of skepticism, fear, or even conspiratorial paranoia.

On the other side of that gag, some humans are making joke videos playing off the idea that they’re merely prompts. RedondoKid used the conceit in a basketball trick shot video, saying “of course I’m going to make this. This is AI, you put that I’m going to make this in the prompt.” User thisisamurica thanked his faux prompters for putting him in “a world with such delicious food” before theatrically choking on a forkful of meat. And comedian Drake Cummings developed TikTok skits pretending that it was actually AI video prompts forcing him to indulge in vices like shots of alcohol or online gambling (“Goolgle’s [sic] New A.I. Veo 3 is at it again!! When will the prompts end?!” Cummings jokes in the caption).

@justdrakenaround Goolgle’s New A.I. Veo 3 is at it again!! When will the prompts end?! #veo3 #google #ai #aivideo #skit ♬ original sound – Drake Cummings

Beyond the obvious jokes, though, I’ve also seen a growing trend of TikTok creators approaching friends or strangers and asking them to react to the idea that “we’re all just prompts.” The reactions run the gamut from “get the fuck away from me” to “I blame that [prompter], I now have to pay taxes” to solipsistic philosophical musings from convenience store employees.

I’m loath to call this a full-blown TikTok trend based on a few stray examples. Still, these attempts to exploit the confusion between real and AI-generated video are interesting to see. As one commenter on an “Are you a prompt?” ambush video put it: “New trend: Do normal videos and write ‘Google Veo 3’ on top of the video.”

Which one is real?

The best Veo-related TikTok engagement hack I’ve stumbled on so far, though, might be the videos that show multiple short clips and ask the viewer to decide which are real and which are fake. One video I stumbled on shows an increasing number of “Veo 3 Goth Girls” across four clips, challenging in the caption that “one of these videos is real… can you guess which one?” In another example, two similar sets of kids are shown hanging out in cars while the caption asks, “Are you able to identify which scene is real and which one is from veo3?”

@spongibobbu2 One of these videos is real… can you guess which one? #veo3 ♬ original sound – Jett

After watching both of these videos on loop a few times, I’m relatively (but not entirely) convinced that every single clip in them is a Veo creation. The fact that I watched these videos multiple times shows how effective the “Real or Veo” challenge framing is at grabbing my attention. Additionally, I’m still not 100 percent confident in my assessments, which is a testament to just how good Google’s new model is at creating convincing videos.

There are still some telltale signs for distinguishing a real video from a Veo creation, though. For one, Veo clips are still limited to just eight seconds, so any video that runs longer (without an apparent change in camera angle) is almost certainly not generated by Google’s AI. Looking back at a creator’s other videos can also provide some clues—if the same person was appearing in “normal” videos two weeks ago, it’s unlikely they would be appearing in Veo creations suddenly.

There’s also a subtle but distinctive style to most Veo creations that can distinguish them from the kind of candid handheld smartphone videos that usually fill TikTok. The lighting in a Veo video tends to be too bright, the camera movements a bit too smooth, and the edges of people and objects a little too polished. After you watch enough “genuine” Veo creations, you can start to pick out the patterns.

Regardless, TikTokers trying to pass off real videos as fakes—even as a joke or engagement hack—is a recognition that video sites are now deep in the “deep doubt” era, where you have to be extra skeptical of even legitimate-looking video footage. And the mere existence of convincing AI fakes makes it easier than ever to claim real events captured on video didn’t really happen, a problem that political scientists call the liar’s dividend. We saw this when then-candidate Trump accused Democratic nominee Kamala Harris of “A.I.’d” crowds in real photos of her Detroit airport rally.

For now, TikTokers of all stripes are having fun playing with that idea to gain social media attention. In the long term, though, the implications for discerning truth from reality are more troubling.

Google and DOJ tussle over how AI will remake the web in antitrust closing arguments

antitrust, Google, search, Tech / Rejus Almole / May 31, 2025

At the same time, Google is seeking to set itself apart from AI upstarts. “Generative AI companies are not trying to out-Google Google,” said Schmidtlein. Google’s team contends that its actions have not harmed any AI products like ChatGPT or Perplexity, and at any rate, they are not in the search market as defined by the court.

Mehta mused about the future of search, suggesting we may have to rethink what a general search engine is in 2025. “Maybe people don’t want 10 blue links anymore,” he said.

The Chromium problem and an elegant solution

At times during the case, Mehta has expressed skepticism about the divestment of Chrome. During closing arguments, Dahlquist reiterated the close relationship between search and browsers, reminding the court that 35 percent of Google’s search volume comes from Chrome.

Mehta now seems more receptive to a Chrome split than before, perhaps in part because the effects of the other remedies are becoming so murky. He called the Chrome divestment “less speculative” and “more elegant” than the data and placement remedies. Google again claimed, as it has throughout the remedy phase, that forcing it to give up Chrome is unsupported in the law and that Chrome’s dominance is a result of innovation.

Even if Mehta leans toward ordering this remedy, Chromium may be a sticking point. The judge seems unconvinced that the supposed buyers—a group which apparently includes almost every major tech firm—have the scale and expertise needed to maintain Chromium. This open source project forms the foundation of many other browsers, making its continued smooth operation critical to the web.

If Google gives up Chrome, Chromium goes with it, but what about the people who maintain it? The DOJ contends that it’s common for employees to come along with an acquisition, but that’s far from certain. There was some discussion of ensuring a buyer could commit to hiring staff to maintain Chromium. The DOJ suggests Google could be ordered to provide financial incentives to ensure critical roles are filled, but that sounds potentially messy.

A Chrome sale seems more likely now than it did earlier, but nothing is assured yet. Following the final arguments from each side, it’s up to Mehta to mull over the facts before deciding Google’s fate. That’s expected to happen in August, but nothing will change for Google right away. The company has already confirmed it will appeal the case, hoping to have the original ruling overturned. It could still be years before this case reaches its ultimate conclusion.

Want a humanoid, open source robot for just $3,000? Hugging Face is on it.

AI, Hugging Face, robotics, Tech / Rejus Almole / May 31, 2025

You may have noticed he said “robots” plural—that’s because there’s a second one. It’s called Reachy Mini, and it looks like a cute, Wall-E-esque statue bust that can turn its head and talk to the user. Among other things, it’s meant to be used to test AI applications, and it’ll run between $250 and $300.

You can sort of think of these products as the equivalent to a Raspberry Pi, but in robot form and for AI developers—Hugging Face’s main customer base.

Hugging Face has previously released AI models meant for robots, as well as a 3D-printable robotic arm. This year, it announced an acquisition of Pollen Robotics, a company that was working on humanoid robots. Hugging Face’s Cadene came to the company by way of Tesla.

For context on the pricing, Tesla’s Optimus Gen 2 humanoid robot (while admittedly much more advanced, at least in theory) is expected to cost at least $20,000.

There is a lot of investment in robotics like this, but there are still big barriers—and price isn’t the only one. There’s battery life, for example; Unitree’s G1 only runs for about two hours on a single charge.

Elon Musk counts the cost of his four-month blitz through US government

Term at DOGE did serious damage to his brands, only achieved a fraction of hoped-for savings.

Elon Musk’s four-month blitz through the US government briefly made him Washington’s most powerful businessman since the Gilded Age. But it has done little for his reputation or that of his companies.

Musk this week formally abandoned his role as the head of the so-called Department of Government Efficiency (Doge), which has failed to find even a fraction of the $2 trillion in savings he originally pledged.

On Thursday, Donald Trump lamented his departure but said Musk “will always be with us, helping all the way.”

Yet the billionaire will be left calculating the cost of his involvement with Trump and the meagre return on his $250 million investment in the US president’s election campaign.

“I appreciate the fact that Mr Musk put what was good for the country ahead of what was good for his own bottom line,” Tom Cole, the Republican chair of the House Appropriations Committee, told the Financial Times.

After Doge was announced, a majority of American voters believed Musk would use the body to “enrich himself and undermine his business rivals,” according to a survey, instead of streamlining the government.

Progressive groups warned that he would be “rigging federal procurement for billionaires and their pals” and cut regulations that govern his companies Tesla and SpaceX. Democratic lawmakers said Doge was a “cover-up” of a more sinister, self-serving exercise by the world’s richest person.

Early moves by the Trump administration suggested Musk might get value for money. A lawsuit brought by the Biden administration against SpaceX over its hiring practices was dropped in February, and regulators probing his brain-implant company Neuralink were dismissed.

Musk’s satellite Internet business Starlink was touted by Commerce Secretary Howard Lutnick as a potential beneficiary of a $42 billion rural broadband scheme. An executive order calling for the establishment of a multibillion-dollar Iron Dome defense system in the US looked set to benefit Musk, due to SpaceX’s dominance in rocket launches.

The gutting of various watchdogs across government also benefited Musk’s businesses, while a number of large US companies rushed to ink deals with Starlink or increase their advertising spending on X. Starlink also signed agreements to operate in India, Pakistan, and Vietnam, among other countries it has long wished to expand into.

But while Doge took a scythe to various causes loathed by Musk, most notably international aid spending and government contracts purportedly linked to diversity initiatives or “woke” research, it also caused severe blowback to the billionaire’s businesses, particularly Tesla.

At one point during his Doge tenure, Tesla’s stock had fallen 45 percent from its highest point last year, and reports emerged that the company’s board of directors had sought to replace Musk as chief executive. The 53-year-old’s personal wealth dropped by tens of billions of dollars, while his dealerships were torched and death threats poured in.

Some of the brand damage to Tesla, until recently Musk’s primary source of wealth, could be permanent. “Eighty percent of Teslas in the US were sold in blue zip codes,” a former senior employee said. “Obviously that constituency has been deeply offended.”

Starlink lost lucrative contracts in Canada and Mexico due to Musk’s political activities, while X lost 11 million users in Europe alone.

Probes of Tesla and SpaceX by government regulators also continued apace, while the Trump administration pressed ahead with plans to abolish tax credits for electric vehicles and waged a trade war vehemently opposed by Musk that threatened to further damage car sales.

In the political arena, few people were cheered by Doge’s work. Democrats were outraged by the gutting of foreign aid and by Musk’s 20-something acolytes gaining access to the Treasury’s payment system, along with the ousting of thousands of federal workers. Republicans looked askance at attempts to target defense spending. And true budget hawks were bitter that Musk could only cut a few billion dollars. Bill Gates even accused Musk of “killing the world’s poorest children” through his actions at Doge.

Musk, so used to getting his way at his businesses, struggled for control. At various points in his tenure he took on Treasury Secretary Scott Bessent, Secretary of State Marco Rubio, Transport Secretary Sean Duffy, and trade tsar Peter Navarro, while clashing with several other senior officials.

Far from being laser-focused on eliminating waste, Musk’s foray into government was a “revenge tour” against a bureaucracy the billionaire had come to see as the enemy of innovation, a former senior colleague of Musk’s said, highlighting the entrepreneur’s frustration with COVID-19 regulations in California, his perceived snub by the Biden administration, and his anger over his daughter’s gender transition.

Trump’s AI and crypto tsar, David Sacks, an influential political voice in the tech world, “whipped [Musk] up into a very, very far-right kind of mindset,” the person added, to the extent that was “going to help this administration in crushing the ‘woke’ agenda.”

Neither Musk nor Sacks responded to requests for comment.

Musk, who claimed Doge only acted in an “advisory role,” this week expressed frustration at it being used as a “whipping boy” for unpopular cuts decided by the White House and cabinet secretaries.

“Trump, I think, was very savvy and allowed Doge to kind of take all those headlines for a traditional political scapegoat,” said Sahil Lavingia, head of a commerce start-up who worked for Doge until earlier this month. Musk, he added, might also have been keen to take credit for the gutting of USAID and other moves but ultimately garnered unwanted attention.

“If you were truly evil, [you] would just be more quiet,” said Lavingia, who joined the initiative in order to streamline processes within government. “You would do the evil stuff quietly.”

The noise surrounding Musk, whose ability to dominate news cycles with a single post on his social media site X rivaled Trump’s own hold on the headlines, also frustrated the administration.

This week, White House Deputy Chief of Staff Stephen Miller took to X to indirectly rebut the billionaire’s criticism of Trump’s signature tax bill, which he had lambasted for failing to cut the deficit or codify Doge’s cuts.

Once almost synonymous with Musk, Doge is now being melded into the rest of government. In a briefing on Thursday, White House Press Secretary Karoline Leavitt said that following Musk’s departure, cabinet secretaries would “continue to work with the respective Doge employees who have onboarded as political appointees at all of these agencies.”

She added: “The Doge leaders are each and every member of the President’s Cabinet and the President himself.”

Doge’s aims have also become decidedly more quotidian. Tom Krause, a Musk ally who joined Doge and was installed at Treasury, briefed congressional staff this week on improvements to the IRS’s application program interfaces and customer service, according to a person familiar with the matter. Other Doge staffers are doing audits of IT contracts—work Lavingia compares with that done by McKinsey consultants.

Freed from the constraints of being a government employee, Musk is increasingly threatening to become a thorn in Trump’s side.

Soon after his Doge departure was announced, he again criticized the White House, this time over its plan to cancel clean energy tax credits.

“Teddy Roosevelt had that great adage: ‘speak softly but carry a big stick’,” Fred Thiel, the chief executive of Bitcoin mining company MARA Holdings, told the FT. “Maybe Elon’s approach was a little bit different.”

Blue Origin boss: Government should forget launch and focus on “exotic” missions

Eighteen months after leaving his job as a vice president at Amazon to take over as Blue Origin’s chief executive, Dave Limp has some thoughts on how commercial companies and government agencies like NASA should explore the Solar System together.

Limp had no background in the space industry before taking the helm of Jeff Bezos’ space company in December 2023. He started his career as a computer scientist at Apple, took a stint at a venture capital firm, and joined Amazon in 2010, where he managed development of consumer devices like Alexa, Kindle, and the Fire TV.

“I had no thoughts of ever running a space company,” Limp said Thursday at a space conference in Washington, DC. “I’ve done consumer electronics my whole life. Started at Apple and did a bunch of other things, and so when I decided to retire from Amazon, I was looking for something that I could give back a little bit, be a little bit more philanthropic in the sort of second half of my career. I didn’t want to stop working, just wanted to do something different. And about that same time, Jeff was looking for a CEO.”

While he’s still a relative newcomer to the space business, Limp’s views align with those of many policy wonks and industry leaders who have the ears of senior officials in the Trump administration, including Jared Isaacman, President Trump’s nominee to become the next NASA administrator. Limp’s long tenure at Amazon and his selection as Blue Origin’s new CEO demonstrate that he also has the trust of Bezos, who was dissatisfied with his company’s slow progress in spaceflight.

“I think Jeff convinced me, and he’s very persuasive, that Blue didn’t need another rocket scientist,” Limp said. “We have thousands of the world’s best rocket scientists. What we needed was a little bit more decisiveness, a little bit more ability to think about: How do we manufacture at scale? And those are things I’ve done in the past, and so I’ve never looked back.”

Leave it to us

In remarks Thursday at the Humans to the Moon & Mars Summit, Limp advocated for commercial companies, like his own, taking a larger role in developing the transportation and infrastructure to meet lofty national objectives established by government leaders.

In some ways, NASA has long been moving in this direction, beginning with initiatives ceding most launch services to private industry in the 1990s. More recently, NASA has turned to commercial companies for crew and cargo deliveries to the International Space Station and cargo and human-rated Moon landers.

However, NASA, with the backing of key congressional leaders, has held an iron grip on having its own heavy-lift launcher and crew capsule to ferry astronauts between Earth and destinations beyond low-Earth orbit. Now, these vehicles—the Space Launch System and Orion spacecraft—may be canceled if Congress agrees with Trump’s proposed NASA budget.

Commercial rockets close to matching or exceeding the Space Launch System’s lift capability are available for purchase or likely will be soon. These include SpaceX’s Starship mega-rocket and Blue Origin’s New Glenn launcher. Both are already key elements of NASA’s Artemis program, which aims to land US astronauts on the Moon as a stepping stone toward human expeditions to Mars.

But NASA still plans to use its government-owned Space Launch System rocket and Orion spacecraft to transport astronauts out to the Moon, where they will rendezvous with a Starship or Blue Origin’s Blue Moon lander to fly to and from the lunar surface.

SLS and Orion are expensive vehicles, costing more than $4 billion per launch for the initial set of four Artemis missions, according to a report by NASA’s inspector general. While commercial companies like Boeing, Lockheed Martin, and Northrop Grumman build elements of SLS and Orion, NASA acts as the prime integrator. The agency signed cost-plus contracts with the companies building SLS and Orion, meaning the government is on the hook for cost overruns. And there have been many.

NASA’s robotic science probes are also getting more expensive, even when accounting for inflation. Given the way NASA procures science probes, it would cost NASA more today to send an orbiter to Mars than it did for a similarly sized spacecraft a quarter-century ago.

This has to change in order for NASA and private companies like Blue Origin and SpaceX to make their ambitions a reality, Limp said Thursday.

“I think commercial folks can worry about the infrastructure,” he said. “We can do the launch. We can build the satellite buses that can get you to Mars much more frequently, that don’t cost billions of dollars. We can take a zero, and over time, maybe two zeros off of that. And if the governments around the world leave that to the commercial side, then there are a lot more resources that are freed up for the science side, for the national prestige side, and those types of things.”

The bottom line

Limp followed these comments with a dose of realism you don’t often hear from space industry executives. While there’s a growing list of commercially viable markets in space (things like Starlink and satellite servicing wouldn’t have been money-makers 20 years ago), the market for human spaceflight still requires some level of government commitment.

“I think the thing about bringing commercial aspects to exploration, to science, to the Moon, to Mars, is that we have to see a business prospect for it,” Limp said. “We have to turn it into a business, and that benefits American taxpayers because we will use that capital as efficiently as we can to get to the Moon, to get to Mars in a safe way, but in a way that’s the most efficient.

“We’re committed to that, no matter what the architecture looks like, but it does take the US government and international governments to have the motivation to do it,” he continued. “There’s not yet a commercial reason only to go to the Moon with humans. There are lots of commercial reasons to put robotics on the Moon and other types of things. So, we do need to have conviction that the Moon is important and Mars is important as well.”

Trump and Musk, an ally and advisor to the president, rekindled the question of Moon or Mars in a series of remarks during the early weeks of the new Trump administration. The Artemis Moon program began during the first Trump administration, with the goal of returning astronauts to the Moon for the first time since 1972. NASA would establish a sustained presence at the Moon, using our nearest planetary body as a proving ground for the next destination for humans in Solar System exploration: Mars.

SpaceX’s Starship, while capable of one day landing on the Moon, was designed for long-duration cruises to Mars. Blue Origin’s Blue Moon is tailored for lunar landings.

“As an American, I don’t want another Sputnik moment,” Limp said. “From my standpoint, getting boots on the Moon and setting the groundwork for permanence on the Moon is of national importance and urgency. Rest assured, Blue will do everything in its power to try to make that happen, but in a cost-effective way.”

NASA, please don’t leave us

Since retaking office in January, Trump has mentioned human missions to Mars multiple times, but not the Moon. Isaacman, who may be confirmed as NASA administrator by the Senate as soon as next week, told lawmakers in April that the agency should pursue human missions to the Moon and Mars simultaneously. The details of how that might work haven’t been released but could come out in the White House’s detailed budget proposal for fiscal-year 2026.

A blueprint of Trump’s spending proposal released May 2 includes a 25 percent cut to NASA’s overall budget, but the plan would provide additional money for human space exploration at the Moon and Mars. “The budget funds a program to replace SLS and Orion flights to the Moon with more cost-effective commercial systems that would support more ambitious subsequent lunar missions,” the White House budget office wrote.

This part of the budget request is not controversial for industry leaders like Limp. On the other hand, the budget blueprint proposes slashing NASA’s space science budget by nearly $2.3 billion, Earth science by almost $1.2 billion, and space technology by $531 million.

While Limp didn’t directly address these budget proposals, these parts of NASA are largely focused on research projects that lack a commercial business case. Who else but a government space agency, or perhaps an especially generous type of philanthropic multi-billionaire, would pay to send a probe to study Jupiter’s icy moon Europa? Or a robot to zip by Pluto? Or how about a mission like Landsat, which documents everything from water resources to farms and urban sprawl and makes its data freely available to anyone with an Internet connection?

Most experts agree there are better ways to do these things. Reusable rockets, mass-produced satellite platforms, and improved contracting practices can bring down the costs of these missions. Bezos’ long-term goal for Blue Origin, which is to move all polluting factories off the Earth and into space, will be easier to achieve with government support, not just funding, Limp said.

“Getting up there, building factories on the Moon is a great step, and the government can really help with research dollars around that,” he said. “But it still does need the labs. The science missions need the JPLs [Jet Propulsion Laboratory] of the world. To make the human experience right, we need the Johnson Space Centers of the world to be able to kind of use that gold mine of institutional knowledge.

“I would say, and it might be a little provocative, let’s have those smart brains look on the forward-thinking types of things, the really edge of science, planning the really exotic missions, figuring out how to get to planetary bodies we haven’t gotten to before, and staying there,” Limp said.

Mark it down

For the first decade after Bezos founded Blue Origin in 2000, the company operated under the radar and seemed to move at a glacial pace. It launched its first small rocket in 2006 to an altitude of less than 300 feet and reached space with the suborbital New Shepard booster in 2015. Blue Origin finally reached orbit in January of this year on the debut test flight of its heavy-lift New Glenn rocket. Meanwhile, Blue Origin inked a deal with United Launch Alliance to supply a version of its New Glenn main engine to power that company’s Vulcan rocket.

Blue Origin’s Blue Moon MK1 lander, seen in the center, is taller than NASA’s Apollo lunar lander, currently the largest spacecraft to have landed on the Moon. Blue Moon MK2 is even larger, but all three landers are dwarfed in size by SpaceX’s Starship, NASA’s other Artemis lunar lander. Credit: Blue Origin

The next big mission for Blue Origin will be the first flight of its Blue Moon lander. The first version of Blue Moon, called MK1, will launch on a New Glenn rocket later this year and attempt to become the largest spacecraft to ever land on the Moon. This demonstration, without anyone onboard, is fully funded by Blue Origin, Limp said.

A future human-rated version, called MK2, is under development with the assistance of NASA. It will be larger and will require refueling to reach the lunar surface. Blue Moon MK1 can make a landing on one tank.

These are tangible achievements that would be the envy of any space industry startup not named SpaceX. But Musk’s rocket company left Blue Origin in the dust as it broke launch industry records repeatedly and began delivering NASA astronauts to the International Space Station in 2020. My colleague, Eric Berger, wrote a story in January describing Blue Origin’s culture. For much of its existence, one former employee said, Blue Origin had “zero incentive” to operate like SpaceX.

To ensure he would be in lock-step with his boss, Limp felt he had to ask a question that was on the minds of many industry insiders. He got the answer he wanted.

“The only question I really asked Jeff when I was talking about taking this job was, ‘What do you want Blue to be? Is it a hobby, or is it a business?'” Limp said. “And he had the right answer, which is, it’s a business, because I don’t know how to run a hobby, and I don’t think it’s sustainable.”

Welcome to Edition 7.46 of the Rocket Report! As I write this, the date is May 29. From a meteorological standpoint, “spring” ends in fewer than three days. Summer lasts from June 1 through August 31. Consider this a public service announcement for launch companies targeting “spring” and “summer” launches for various missions.

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.

Xodiac rocket makes its final flight. Originally built by Masten Space Systems, the suborbital Xodiac rocket had flown 175 successful missions before a flight from Mojave, California, on Wednesday. But now, it will fly no more. “While the vehicle remained within its planned flight envelope, it detected an anomalous condition and commanded a flight termination,” said Astrobotic, which acquired Masten a couple of years ago. “This resulted in a rapid descent and caused a loss of the vehicle upon impact with its launch pad.”

Now entering the Xogdor waiting room … There were no injuries or significant damage to the company’s infrastructure in Mojave. The vehicle is essentially a hopper and has been used in recent years by various customers, including companies building commercial lunar landers, to test their hazard-detection systems. Astrobotic has been working on a larger version of Xodiac, which it is calling Xogdor.

Chinese firm tests Grasshopper-like rocket. Chinese private rocket firm Space Epoch said Thursday it had successfully run a flight recovery test, Reuters reports. Beijing-based Space Epoch, or SEPOCH, said its Yuanxingzhe-1 verification rocket was launched at 4: 40 am from a sea-based platform off the waters of the eastern province of Shandong. The rocket soared upward, its engines briefly shutting down after the peak of its trajectory, then reigniting as it began its vertical descent to enter the Yellow Sea in a circle of fire, a video posted on Space Epoch’s WeChat account showed.

Chasing the Falcon 9 … The flight lasted 125 seconds, reaching a height of about 2.5 km (1.6 miles), the company said. Last year, another Chinese launch company, LandSpace, completed a 10-km (6.2-mile) VTVL test, marking China’s first in-flight engine reignition in descent. Both companies are pushing to make debut tests of their reusable rockets later this year.

Florida company aims to acquire F-4 Phantoms for launch. Starfighters International, a company best known for doing air shows, is now seeking to move into air launch. Based at Kennedy Space Center, the company is in the process of acquiring a dozen F-4 Phantoms, a Cold War-era fighter jet, TWZ reports. Starfighters International is seeking to acquire the F-4 aircraft from South Korea.

Press F-4 to doubt? … Based upon the information in a filing with the Securities and Exchange Commission, the company is considering both a suborbital and orbital launch capability for small satellites, which would fly to space on a small rocket deployed from the F-4 Phantom. In my experience, air-based launch systems always seem like a better idea on paper than in reality. Perhaps there is some potential for hypersonics here, but I would be shocked to ever see a satellite launched into orbit from a fighter jet. (submitted by Biokleen)

Rocket Lab acquires Geost. Rocket Lab is expanding deeper into the defense sector with the acquisition of Geost, a supplier of electro-optical and infrared sensor payloads used in US military satellites, Space News reports. In a deal announced Tuesday, Rocket Lab will acquire Geost from the private equity firm ATL Partners for $125 million in cash and $150 million in stock, with an additional $50 million in potential cash payments tied to revenue targets in 2026 and 2027.

Seeking mil money … The acquisition gives Rocket Lab access to satellite sensor technology used by the US Department of Defense for missile-warning systems and space surveillance—capabilities that could help it win lucrative Pentagon contracts. “The acquisition of Geost will bring on board critical technology and payloads that are relied upon by the Department of Defense,” said Rocket Lab’s chief executive, Peter Beck. Rocket Lab has been seeking to expand its military contracts in recent years, and this move is consistent with that.

Northrop names rocket, invests in Firefly. Northrop Grumman announced Thursday that it is investing $50 million into Firefly Aerospace to further development of a medium-lift rocket. The company also revealed that the rocket will be named “Eclipse.” The rocket will be capable of launching up to 16,300 kg of cargo to low-Earth orbit or 3,200 kg of cargo to geosynchronous transfer orbit, and initially it will likely be used for Cygnus cargo missions to the International Space Station.

A match made in heaven? … Eclipse will use the same first stage Firefly is developing for the Northrop Grumman Antares 330 rocket. Both launch vehicles will use seven of Firefly’s Miranda engines. The new rocket is expected to make its debut no earlier than 2026 (and, if history is any guide, probably later). “Eclipse gives customers the right balance of payload capacity and affordability,” Northrop Vice President Wendy Williams said in a statement. “Our partnership with Firefly builds on our capacity to provide crucial space-based communication, observation, and exploration for civil and national security customers.”

China launches asteroid mission. A Chinese spacecraft built to collect specimens from an unexplored asteroid and return them to Earth launched Wednesday from a military-run spaceport in the country’s mountainous interior, Ars reports. The liftoff aboard a Long March 3B rocket from the Xichang launch base kicked off the second mission in a series of Chinese probes to explore the Solar System. This mission, designated Tianwen-2, follows the Tianwen-1 mission, which became the first Chinese spacecraft to land on Mars in 2021.

Sending samples home … China has two objectives for Tianwen-2. First, Tianwen-2 will fly to a near-Earth asteroid designated 469219 Kamoʻoalewa, or 2016 HO3. Once there, the spacecraft will retrieve a rocky sample from the asteroid’s surface and bring the material back to Earth in late 2027 for analysis in labs. After the spacecraft releases its sample carrier to land on Earth, Tianwen-2 will change course and head to a mysterious comet-like object found between the orbits of Mars and Jupiter.

Next Kuiper launch gets a June date. United Launch Alliance said Thursday that an Atlas V rocket will launch its second batch of Amazon’s Project Kuiper satellites next month. The Atlas V 551 rocket launch is planned for 2: 29 pm ET on June 13 from Space Launch Complex-41, pending range approval.

A speedy turnaround … Amazon also confirmed that it has finished processing the Kuiper satellites for the launch, saying all 27 spacecraft have been integrated onto the rocket. Getting to space in June with this mission will mark an impressive turnaround from Amazon, given that its KA-01 mission, also with 27 Internet satellites, launched on April 28.

SpaceX set to launch another GPS satellite. SpaceX is gearing up to launch a Global Positioning System satellite for the US military on Friday from Cape Canaveral Space Force Station, Florida, marking another high-profile national security mission that shifted from United Launch Alliance’s Vulcan to the Falcon 9 rocket, Space News reports. The launch of GPS III SV-08—the eighth satellite in the GPS III constellation—was originally assigned to United Launch Alliance but was switched to SpaceX as the military prioritizes getting advanced anti-jamming capabilities into orbit as quickly as possible.

Gotta go fast … This marks the second consecutive GPS III satellite to be switched from ULA to SpaceX, following December’s launch of GPS III SV-07. ULA’s Vulcan, which received certification to launch national security missions, continues to face delays and has accumulated a backlog of military launches. In a press call this week, Space Force officials said the mission was executed on an unusually accelerated timeline. Launch planning for GPS III SV-08 kicked off in February, with Lockheed Martin receiving a formal request on February 21 and SpaceX following on March 7, just under three months ahead of liftoff. That’s an extraordinary pace for a national security launch, they said, which typically takes 18 to 24 months from contract award.

Another Starship launch, another second-stage issue. SpaceX made some progress on another test flight of the world’s most powerful rocket Tuesday, finally overcoming technical problems that plagued the program’s two previous launches, Ars reports. But minutes into the mission, SpaceX’s Starship lost control as it cruised through space, then tumbled back into the atmosphere somewhere over the Indian Ocean nearly an hour after taking off from Starbase, Texas, the company’s privately owned spaceport near the US-Mexico border. During the rocket’s two previous test flights—each using an upgraded “Block 2” Starship design—problems in the ship’s propulsion system led to leaks during launch, eventually triggering an early shutdown of the rocket’s main engines.

Not great, not terrible … On both flights, the vehicle spun out of control and broke apart, spreading debris over an area near the Bahamas and the Turks and Caicos Islands. The good news is that that didn’t happen on Tuesday. The ship’s main engines fired for their full duration, putting the vehicle on its expected trajectory toward a splashdown in the Indian Ocean. For a short time, it appeared the ship was on track for a successful flight. The bad news is that Tuesday’s test flight revealed more problems, preventing SpaceX from achieving the most important goals Musk outlined going into the launch, including testing Starship’s reentry tiles.

Elon Musk talks Starship version 3. In an interview with Ars Technica, SpaceX founder Elon Musk said he expects that an upgraded version of Starship—essentially Block 3 of the vehicle with upgraded Raptor engines—should fly before the end of the year. The business end of the rocket will have a sleek look: “The upgraded Raptors have a complete redesign of the aft end of the booster and the ship,” Musk said. “So, because we don’t need the heat shield around the upper portion of the engine, it greatly simplifies the base of the booster and the ship. It’ll look a little, frankly, naked, especially on the booster side, because the engines will just be there, like, not with stuff around them.”

A difficult upgrade to work through … “This is a design change that I really had to push the team very hard to do, to get rid of any secondary structure, and any parts that could get burned off because there will be no heat shield,” Musk added. “So it’ll be very clear when we have a Raptor 3. Version 3 of the Ship and Booster has quite a radical redesign.” Given the challenges that version 2 of Starship has faced with its recent flights, an upgrade in the overall design appears to be much-needed.

Comet 311P/PanSTARRS was observed by the Hubble Space Telescope in 2013 with a set of six comet-like tails radiating from its main body. This object, also called P/2013 P5, is known as an active asteroid. Credit: NASA, ESA, and D. Jewitt (UCLA)

Tianwen-2’s mothership, with 11 scientific instruments, will commence the second phase of its mission after dropping off the asteroid specimens at Earth. The probe’s next journey will bring it near an enigma in the asteroid belt, named 311P/PanSTARRS, in the mid-2030s. This object is one in a rare class of objects known as active asteroids or main-belt comets, small worlds that have tails and comas like comets but loiter in orbits most commonly associated with asteroids. Tianwen-2 will be the first mission to see such an object up close.

Stepping into the Solar System

Until the last few years, China’s space program has primarily centered on the Moon as a destination for scientific exploration. The Moon remains the main target for China’s ambitions in space, with the goal of accomplishing a human lunar landing by 2030. But the country is looking farther afield, too.

With the Tianwen-1 mission in 2021, China became the second country to achieve a soft landing on Mars. After Tianwen-2, China will again go to Mars with the Tianwen-3 sample return mission, slated for launch in 2028.

Tianwen, which means “questions to heaven,” is the name given to China’s program of robotic Solar System exploration. Tianwen-3 has a chance to become the first mission to return pristine samples from Mars to Earth. At the same time, NASA’s plans for a Mars Sample Return mission are faltering.

China is looking at launching Tianwen-4 around 2029 to travel to Jupiter and enter orbit around Callisto, one of its four largest moons. In the 2030s, China’s roadmap includes a mission to return atmospheric samples from Venus to Earth, a Mars research station, and a probe to Neptune.

Meanwhile, NASA has sent spacecraft to study every planet in the Solar System and currently has spacecraft at or on the way to the Moon, Mars, Jupiter, a metal asteroid, and to interstellar space. Another US science mission, Dragonfly, is scheduled for launch in 2028 on a daring expedition to Saturn’s moon Titan.

But NASA’s science division is bracing for severe budget cuts proposed by President Donald Trump. In planetary science, the White House’s budget blueprint calls for canceling a joint US-European Mars Sample Return mission and several other projects, including the DAVINCI mission to Venus.
