In the two years since it made a largely successful debut, Europe's Ariane 6 rocket has launched eight missions, all of which reached orbit safely.

The large, expendable rocket has a capacity of more than 20 metric tons to low-Earth orbit. And to the credit of European rocket scientists and planners, the Ariane 6 has had a substantially smoother rollout than comparable vehicles in the United States—Blue Origin's New Glenn and United Launch Alliance's Vulcan rockets—both of which have had significant growing pains.

However, even though the Ariane 6 rocket has had a successful debut, its future is clouded by high costs.

September 11, 2001, will be remembered as one of the darkest days in American history. As the 25th anniversary approaches, National Geographic, in collaboration with the 9/11 Memorial and Museum, is marking the occasion with a new documentary miniseries: 9/11: Reunited . The three-episode series revisits the personal stories of several survivors of the terrorist attacks, with a twist: It reunites people whose paths crossed at that time to celebrate the bonds they formed 25 years ago.

Director Julian Jones was a producer on NatGeo's Emmy-winning 2021 documentary miniseries 9/11: One Day in America . The experience inspired him to return to direct 9/11: Reunited . "What emerged for me [while making the 2021 documentary] was a sense of people showing up for each other, a selflessness and everyday heroism," Jones told Ars. As the 25th anniversary of the attacks approached, he and National Geographic decided to commemorate the milestone with a documentary series focused on that aspect.

"We wanted to bring people together to offer gratitude to each other, to answer unanswered questions, to talk about things that maybe they weren't ready to talk about until now, and also to remember their fallen comrades or friends," said Jones. "After 25 years, who do they want to meet? What questions have they got? I think we also wanted to tell the story of what many in the 9/11 community call 9/12, that's the rest of your lives—the journey, and in many cases, the psychological and physical struggles."

Despite making changes last fall to help block adults from messaging unknown children , Roblox is still failing to stop adults from creeping on kids in other ways, Australia’s eSafety commissioner, Julie Inman Grant, said on Thursday.

Suspecting that Roblox may not be doing enough to stop child exploitation, eSafety conducted testing earlier this year that flagged alarming gaps in Roblox safeguards. The agency found that adult strangers could still send connection requests to kids, whose “profiles and biographies, including account names, number and names of connections, avatar images, and non-sensitive biographical information such as their interests were visible to anyone on the Roblox platform, with no option to restrict the visibility of this information.”

Such requests did not trigger parental alerts, eSafety found, and bad actors could also search kids’ visible-to-anyone contact lists for more targets.

A couple of years ago, Genesis showed us its unique take on the luxury electric SUV with the Neolum concept. The brand's designers know how to draw a handsome shape, particularly using an SUV's proportions, and the clean-lined concept featured a four-seat interior with no B pillar, swiveling front seats, and a thoughtful mix of leather, wool, and even wood. Now Genesis has debuted the production version as its new electric flagship, the GV90. And based on the photos, at least, the process of turning that concept into reality has been a success.

The GV90 uses the same 800 V E-GMP platform as other Korean electric three-row SUVs, the Hyundai Ioniq 9 and Kia EV9. A three-row, seven-seat GV90 will be part of the range, and I would assume the most common variant we'll encounter on the roads. But for the launch, Genesis is just focusing on the four-seat GV90 and the high-end GV90 Neolum; the latter faithfully translates most of the concept, including the pillarless coach doors (which Genesis is calling the Neolum Arch Gate).

Pillarless coach doors certainly add drama to a vehicle, and Genesis has previously told Ars it learned enough to engineer them with all the safety requirements volume production would require. Speaking of safety, all GV90s include the world's first roof airbag (which deploys in the case of a rollover), one of 12 airbags throughout the interior.

Elon Musk’s talk about maintaining a million-strong AI data center satellite megaconstellation may not exactly be practical or economical , but it might be unique. It’s about the closest we’ve come to confronting a scheme that would export a considerable amount of valuable materials into space. Humans aren’t doing a great job of material sustainability, but normally we’re talking about stuff escaping a recycling pipeline rather than escaping Earth’s gravitational pull .

The commercial space sector likes talking about the allure of mining asteroids for precious metals to bring back to Earth. Under what circumstances are we going to be willing to do that in reverse? Starlink alone has doubled the mass of objects in low-Earth orbit, and this orbital data center constellation would dwarf that—and dispose of at least some satellites by pushing them away from Earth.

Given the roughly five-year expected lifetime for data center GPUs, about 200,000 of the 1 million proposed SpaceX AI1 satellites would be decommissioned each year. Based on their May 29 FCC filing , about 40,000 would definitely deorbit and burn up in the atmosphere. (Those materials would largely be dispersed throughout the atmosphere, turning a resource into a diffuse contaminant that slowly settles over the globe. One related issue: the aluminum would cause an unknown amount of ozone depletion over a period of decades.) Some or all of the remaining 160,000 satellites would be moved outward into a distant “disposal” orbit, instead. Either way, they're lost from a "material life cycle" point of view.

When someone uploads a photo to the people-search tool ClarityCheck, the website has a clear message: “Your reverse image search is private and secure.” New research , though, shows that the website left more than 9 million image files, including photographs of people’s faces, publicly exposed . And a second misconfiguration publicly exposed people’s email addresses and phone numbers.

Overall, according to findings from independent security researcher Jeremiah Fowler, the exposed ClarityCheck database contained roughly 450 GB of images, including what appeared to be profile images, screenshots, and other photographs of adults, teenagers, and children. All of the images were stored in an unsecured Amazon S3 bucket, with files in folders named “faces” and “profiles,” which could be accessed by anyone online through a URL included in the company’s publicly available website code.

ClarityCheck is one of a number of so-called people-finder tools that have appeared online in recent years. These websites broadly claim to be able to search the web, public records, and other databases to identify individuals. ClarityCheck’s website says it can run searches on phone numbers, email addresses, vehicle identification numbers, and names. Its photo-search page says it can help “identify anyone in a photo” and find social media profiles “in seconds.”

Earlier this week, researchers outlined an attack that used a secret input provided by Microsoft 365 Copilot for enterprise to cause the AI assistant to exfiltrate a password present in the user’s inbox. Now, a separate team has devised a similar attack against Grok. The new data theft hack employs a deceptively simple trick to force the Elon Musk-owned LLM to steal user chats and other personal information. At the time this post went live, the assistant continued to cough up the data, despite xAI being informed of it in June.

The lesson from both this week’s episodes—and the countless other ones that have come before it—is that LLMs are incapable of solving the root causes for prompt injections, the most severe vulnerability classes they’re most prone to. That leaves AI developers with no other option but to build a guardrail that steers the model away from the harmful actions. As I noted in Tuesday’s story , the approach is tantamount to a road traffic safety engineer erecting a protective rail around a dangerous bend rather than banking the curve.

Cryptographic Context Injection in the house

Prompt injections exploit LLMs' training to comply with user requests whenever possible. Attackers can capitalize on the predilection by smuggling harmful instructions into emails or webpages the assistant is instructed to summarize. Because LLMs can’t reliably distinguish between content in an email sent by an untrusted party and user instructions entered directly into a prompt, the overly solicitous LLM faithfully follows them. To date, Grok and other LLMs' only recourse is to create guardrails that flag suspicious instructions and forbid them from being executed.

NASA and Katalyst Space Technologies announced Wednesday they are giving up on a robotic mission to rescue the Swift gamma-ray telescope before it falls out of orbit.

The rescue satellite, named Link, launched July 3 on a journey to fly up to NASA's Neil Gehrels Swift Observatory, capture it with three robotic arms, and boost its orbit high enough to escape a looming reentry. Link is about the size of a refrigerator, with two power-generating solar arrays and three xenon-fueled electric thrusters to send Swift into a safer, higher orbit.

Katalyst, the startup leading the Swift rescue effort, said Wednesday that "ongoing attitude control issues" will prevent the Link satellite from completing its rescue mission. The spacecraft is still alive, and Katalyst said it will make the most of Link's remaining capacity, which may still allow it to get near enough to Swift for a demonstration of the satellite's close-in navigation system.

Amazon wants to grow its Prime Air delivery drone service sixfold to reach nearly 500 cities and towns across the United States by the end of 2026. The planned expansions from Amazon and its rivals could make the convenience of delivery drone services available to tens of millions more people in the coming months—but will also test more communities’ tolerance for increased noise from daily drone flights.

On August 19, Amazon announced it would soon launch Prime Air in the metropolitan areas of Chicago; Cleveland; Atlanta; Syracuse, New York; and Boise, Idaho, with more to come later in the year. Each Prime Air site offers delivery drone service within an area of about 175 square miles, with delivery times ranging from half an hour to an hour.

Prime Air already operates out of Amazon warehouses in 10 cities across seven states. Those include primarily suburban neighborhoods of Phoenix; Tampa; Kansas City; Omaha, Nebraska; Baton Rouge, Louisiana; Detroit; Houston; and San Antonio, Dallas, and Waco, Texas.
