Buying a car is only the beginning. Every year afterward, drivers face a steady stream of expenses—from insurance and fuel to repairs and taxes—that can add up to thousands of dollars:

Using data from LendingTree, this map compares average annual car ownership costs across every U.S. state and Washington D.C., excluding car payments, revealing where those ongoing expenses place the biggest burden on drivers.

[...] Annual ownership costs range from roughly $3,000 in New Hampshire to more than $6,100 in Nevada, meaning two drivers with the same vehicle could face a difference of more than $3,000 every year based solely on where they live.

Seven of the 15 most expensive states are in the South, largely because of elevated insurance premiums. Florida and Louisiana rank near the top for insurance costs, while California stands out for high fuel prices and repair expenses rather than insurance alone.

[...] Transportation is one of the largest household expenses after housing, making recurring vehicle costs an important part of overall affordability. While consumers often focus on a car's purchase price or monthly payment, insurance, fuel, repairs, and taxes can add thousands of dollars each year, and those costs depend heavily on where they live.

That burden is especially significant in communities where driving is a necessity rather than a choice. Beyond commuting, vehicles are essential for work, school, childcare, and everyday errands, making recurring ownership costs difficult to avoid.

TL;DR - Highest is Nevada at $6.1k/year, lowest is New Hampshire at $3.0k/year. US average is $4.5k/year.

Henkel's Julie Joseph explores the aspects of the sector she would change and the personality traits most suited to a career in this space.

“What drew me towards this career area was my enjoyment of problem solving and understanding how things work. I have always been naturally curious, so I could easily have ended up in many different STEM careers,” explained Julie Joseph, a technology specialist at Henkel.

Particularly interested in chemistry and how it combines scientific thinking with practical applications that can make a real difference in industry and manufacturing, she went on to complete a PhD in polymer chemistry and developed specialist technical knowledge.

She said, “After finishing my studies, I initially worked in research and development for many years. Those roles suited my background well because they involved experimentation, innovation and continuous learning. I enjoyed investigating scientific problems and helping develop new materials and technologies. 

Later in my career, I was given the opportunity to move into a more customer-focused role, where I now work with customers to solve design and production issues involving Henkel’s adhesives. That move was a major turning point for me because it allowed me to combine technical problem solving with communication and collaboration. One of the things I enjoy most is that I work with many different people and industries and no two challenges are exactly the same. There is often a stereotype that STEM careers involve sitting alone in a laboratory, but my experience has been very different. I regularly work with engineers, manufacturers and customers and I enjoy helping people find practical solutions to complex problems.

The thing I enjoy most about my job is the variety. Every day is different, which means the work never becomes repetitive. I help current and potential customers solve technical and manufacturing problems, so there is always a new challenge to investigate and a different solution to develop. I enjoy the satisfaction that comes from helping someone overcome an issue and improving the way a product or process works. Another part of the role that I enjoy is meeting and working with different people. Some meetings take place in person while others happen online through Microsoft Teams, but communication is always a huge part of my work. 

Technical knowledge is important, but it is equally important to explain ideas clearly, listen carefully and collaborate effectively. I enjoy that balance between science and communication because it makes the role much more dynamic and rewarding.

I also enjoy the fact that I am constantly learning. STEM industries evolve quickly, with new technologies, materials and manufacturing methods being introduced all the time. There is always something new to understand, which keeps my brain active and makes the work interesting.

There have been many exciting developments since I started working in the sector, particularly in materials science and computing. New adhesive technologies have allowed manufacturers to create stronger, lighter and more efficient products across industries such as automotive and electronics. However, the biggest development I have witnessed has been the continued rise of computing and digital technology. When I first started working in research and development, many processes were slower and more manual. Today, advanced software, modelling systems and digital communication tools have completely changed the way scientists and engineers work. We can now analyse data more quickly, collaborate globally and solve problems far more efficiently than before. 

More recently, generative AI has created another major shift in the industry. AI tools can help generate ideas, process information and improve productivity at incredible speeds. I find this development particularly fascinating because it is transforming the way people work with technology. At the same time, human judgement and expertise remain essential.

If I could change one thing within the STEM sector, it would be the perception that scientists and engineers lack communication skills or creativity. In reality, successful STEM careers require much more than technical knowledge alone. Collaboration, innovation and communication are all extremely important. In my own role, communication is essential. I work closely with customers to understand their challenges and help them find practical solutions. That means I need to explain technical concepts clearly, listen carefully and build strong working relationships. Without effective communication, even the best technical ideas may not succeed.

I would also like people to recognise how creative STEM careers can be. Problem solving often involves thinking differently, experimenting with new ideas and developing innovative solutions. STEM is not just about formulas and calculations, it is also about creativity and imagination.

I think curiosity is one of the personality traits that makes me best suited to my role. I enjoy learning about new technologies, understanding how products are manufactured and finding ways to improve processes. In STEM careers, curiosity is extremely important because industries are constantly evolving. Adaptability is another key trait. Throughout my career I have moved from research and development into a more customer-focused role, which required me to develop new skills and approaches. STEM careers change rapidly, so being willing to adapt and continue learning is essential. I also believe communication skills are important. I enjoy working with people, discussing ideas and helping customers solve problems, which makes the work both engaging and rewarding.

My main advice would be to stay curious, adaptable and open to opportunities. STEM careers are constantly changing because technology and scientific knowledge continue to evolve. Being willing to learn and develop new skills is extremely important. I would also encourage people not to think of STEM careers as purely technical. Modern STEM roles often involve teamwork, communication and collaboration with many different people and industries. Developing interpersonal skills can therefore be just as valuable as developing technical expertise. Finally, I would encourage people not to be discouraged by challenges. STEM careers often involve solving difficult problems, but overcoming those challenges is also what makes the work rewarding. For anyone who enjoys learning, problem solving and innovation, STEM can be an exciting and fulfilling career path.

Gartner projects global data center electricity use hitting 565 TWh in 2026 and topping 1,200 TWh by 2030:

Conventional servers are effectively flat by comparison. They grew less than 1% in 2025 and are projected to rise 1.2% in 2026 to around 195 TWh, reaching 200 TWh in 2027. Gartner estimates AI-optimized servers will make up 31% of total data center power consumption in 2026, up from roughly 20% a year earlier. Cooling, of course, represents a growing share of the total, with electricity used by cooling systems forecast to climb 22.6% in 2026 to 195 TWh, reflecting the thermal load of denser AI racks and continued capacity expansion.

The U.S. accounts for about 204 TWh of the 565 TWh total in 2026, or 36% of worldwide consumption. Of that U.S. figure, dedicated AI data centers consume roughly 68 TWh, or one-third of the national total, while non-AI data center demand in the country has grown only marginally over the same period.

Regional grids are already feeling the strain, and more than 75 data center projects worth $130 billion were blocked in the first months of 2026 amid opposition over power and water costs, while some operators have turned to on-site gas generators to bring capacity online without waiting for grid connections. In Virginia, one county asked employees to conserve power as data center demand pushed utility rates higher.

In its report, Garner warns that grid supply will be insufficient to meet demand once consumption passes 1,200 TWh by 2030, a shortfall that will affect all data center users, not just AI operators. The forecast accounts for parts and supply shortages, delayed or cancelled projects, and geopolitical disruption, including conflict involving Iran. Wang said infrastructure and operations leaders should prioritize efficiency upgrades, secure grid access, and invest in high-efficiency cooling and edge computing to manage the constraint.

Hyperscalers have moved in the same direction, with Meta having signed deals for more than 6GW of nuclear power to supply its upcoming data centers, and one firm repurposing retired U.S. Navy reactors for an AI site in Tennessee. Those projects will take years to deliver, with recommissioned nuclear plants and the earliest small modular reactors not expected online until 2028 or later, leaving power availability as a near-term limitation on the seemingly unstoppable AI build-out.

AI coding agents can be tricked into installing malware via 'clean' GitHub repositories — Mozilla's 0din team shows how Claude Code can be exploited by its own helpfulness:

"Think out of the box" is painted onto millions of motivation posters across the world, a shooting message for middle managers and eliciting eyerolls from most everyone else. And yet that's exactly what the researchers at Mozilla's 0din did, by tricking Claude into running malware in a roundabout yet deceptively simple way, by merely asking it to initialize a project from a pretty clean-looking GitHub repository.

An attacker would then have control over the developer's own account, accessing all their secrets, API keys, code, documents, browser sessions, and passwords. They could even install additional malware to maintain permanent access. Suffice to say, almost every bot agent is susceptible to this type of attack, though Claude is the default choice for programming tasks.

Here's how it works. All a victim developer has to do is tell Claude to initialize a project from a malicious GitHub repository (or tell it to configure it after cloning it themselves). Said repo looks pretty clean, with just a handful of scaffolding files, and most importantly, nothing that will trigger security tools, whether remote, local, or even Claude's own checks.

Claude will clone the repo. The first file it will process will be a "readme" or Markdown file describing how to initialize a Python environment with the Axiom package, a commonly used monitoring tool. So far, this appears completely legitimate. However, there's a fake Axiom startup script that will simply error out the first time it's run. This is the first step that tricks the box, because in order to be helpful and solve the problem, it'll run another innocuous-looking command to initialize Axiom: "python3 -m axiom init".

This then triggers a shell script that downloads a bit of software to run, another standard operation that won't raise an eyebrow. But the second trick is that instead of downloading from a malicious URL that could be scanned, the script reads the DNS text records of a specific domain — in this case, the domain "_axiom-config.m100.cloud". This too looks kosher enough, as for example, e-mail and by extension its configuration tools extensively rely on TXT records.

The said TXT record contains an encoded (base64) string that just opens a reverse shell, meaning it'll open a shell on the user's machine, but redirected to the attacker's server for input. At this point, the malfeasants can fish out everything that the user has access to and proceed to run software as the user. Meanwhile, all that Claude and the victim see is an "Environment ready" message or similar.

If you've been counting, this is three steps of indirection, none of which in isolation look like anything much out of the ordinary. Very few (if any) security scanning tools would even flag the repository, and none of the activity, save for the actual opening of a remote shell, even looks particularly odd. An enterprise environment with very tightly controlled network access could catch it, but that's not where the vast majority of developers operate in. It's also worth stressing that this particular implementation is just one example of a concept that can be applied to even more indirect and elaborate methods.

The 0din team concludes its report by stating the reasonably obvious: that developers should never blindly trust an unknown project as trusted code, and naturally, not trust the AI tool itself for security analysis purposes. As for the agents themselves, 0din states they need to inspect what actually will run and how, instead of simply following steps.

https://www.theregister.com/public-sector/2026/07/09/mps-tell-nhs-to-start-packing-palantirs-bags-ahead-of-2027-contract-break/5269146

A cross-party group of MPs has told the government to start planning for life after Palantir, arguing the NHS should use a 2027 break clause in its Federated Data Platform (FDP) contract to find a replacement rather than doubling down on one of Whitehall's most contentious tech deals.

In a letter to Health Innovation Minister Preet Kaur Gill, the House of Commons Health and Social Care Committee said the Department of Health and Social Care (DHSC) should begin preparing to replace the FDP when the contract reaches its break clause in February 2027. Rather than waiting until the deadline looms, MPs want ministers to begin assessing alternatives now so a replacement could be in place by March 2027 if they decide not to continue with Palantir.

MPs reached that conclusion after grilling ministers and NHS England officials last month over the platform's supposed benefits. Since then, NHS England has quietly rewritten its website, dropping claims that the FDP was responsible for cutting waiting lists and boosting the number of procedures. It now says it "cannot therefore draw conclusions about cause and effect as other variables have not been controlled for."

The committee said there remains "serious mistrust" of Palantir among the public, warning that the company's involvement with NHS data could discourage patients from allowing their information to be used. MPs argued that loss of confidence could undermine the NHS's wider push to make better use of patient data across the health service.

The committee also seized on the government's admission that some NHS trusts already have capabilities beyond those offered by the FDP. If that's the case, MPs argue, there's no reason Palantir should be treated as the only option for the rest of the health service.

MPs are now asking the DHSC to set out what assessment it will carry out before deciding whether to exercise the break clause, as well as what advice it has received on replacing the platform by March 2027.

Health and Social Care Committee chair Layla Moran said: "Little by little, the government's arguments for sticking with the FDP has [sic] unravelled. So in the interest of public confidence in the NHS and the security of their medical information, we believe it is time to crack on with preparations to find an alternative in time for spring 2027."

"The FDP may have had some advantages, but there are also downsides and it is evidently not the only show in town," she added.

The recommendation adds to the pressure on ministers over the future of Palantir's NHS deal. Another Commons committee has already urged the government to use the 2027 break clause, while campaigners and privacy advocates have spent months questioning everything from procurement and transparency to whether the platform's claimed benefits can be backed by evidence. 

The DHSC did not respond to The Register's questions, and whether it's ready to start shopping for a Palantir successor remains unclear.

Microsoft admits Windows 11 has a GDID tracker with no off switch, first documented publicly in an FBI hacker complaint:

A 19-year-old walked through Helsinki airport in April 2026 carrying two 2TB hard drives and a ticket to Japan. He couldn't make that flight. Finnish police stopped him on an Interpol Red Notice, and by July, US prosecutors had unsealed a federal complaint identifying him as Peter Stokes, an alleged member of the Scattered Spider hacking group, wanted over a May 2025 breach of a US luxury jewelry retailer that ended in an $8 million ransom demand.

[...] it was Microsoft that handed the FBI a way to trace Stokes' Windows PC across VPNs, proxy servers, and three countries. The tool is called a Global Device Identifier, or GDID , and outside a handful of enterprise documentation pages, most Windows users had never heard the term before this case made it public.

We went through the full 39-page complaint, cross checked it against independent reverse engineering of how Windows generates and transmits this identifier, and fact checked the technical claims since the story broke. Here is everything you need to know about GDID, how it caught Stokes, and what it means if you are one of the 1.6 billion people using Windows PCs.

The complaint quotes a Microsoft representative describing the GDID as "a persistent, device-level identifier designed to uniquely identify an installation of a Windows operating system on a device, either a physical device (e.g., a mobile phone or laptop) or virtual machine, across certain Microsoft services and scenarios"

A Global Device ID (GDID) is a permanent, unique digital fingerprint that Microsoft automatically assigns to your computer when you install Windows or sign into a Microsoft account.

Microsoft uses it to manage software licensing and Windows Store apps, but because it links all your online activities on that computer back to a single identity, law enforcement can use it to track a device's true owner across the internet

It survives Windows updates. It does not survive a clean reinstall, and Microsoft's footnote in the complaint admits "one Microsoft user could have multiple GDIDs" over the life of a single account.

Microsoft said what the GDID does without saying where it is inside Windows. For that, independent researchers had to reverse engineer it, because Microsoft has published exactly one sentence about GDID in the Azure Monitor reference for Delivery Optimization reporting , where a column called GlobalDeviceId is described only as "Microsoft global device identifier. This is an identifier used by Microsoft internally."

The real chain starts with the Microsoft Account service.

When Windows provisions a device against a Microsoft Account, a system service called wlidsvc talks to login.live.com and gets back what Microsoft calls a Device PUID, a Passport Unique ID, inside the server's SOAP response. Server assigned. Windows never computes it locally from anything on your PC. It receives a string and stores it.

The PUID lands in your own registry hive, in plain text, at HKCU\SOFTWARE\Microsoft\IdentityCRL\ExtendedProperties under a value named LID. From there, the Connected Devices Platform, the same background service (cdp.dll, running as CDPSvc) that powers Phone Link , cloud clipboard , and Nearby Share, reads that PUID and registers it into Microsoft's Device Directory Service, which is the identity graph behind all of Microsoft's cross device features. There, the number gets a lowercase g stuck in front and gets written as g:decimal. Delivery Optimization then reports that same value back to Microsoft's servers as UCDOStatus.GlobalDeviceId every time your PC shares or downloads update data peer to peer.

Reinstall Windows and you get a new number, but Microsoft's own records give every reason to link the new one back to the old, through the same account, OneDrive, and activation history, which is close to what happened to Stokes.

This UK Satellite's Thermal Camera Raises Major Privacy Concerns

Modern technology often comes with safety concerns, including everything from mobile apps that track your location to traffic cameras that store your personal information. Those concerns also extend to SatVu's HotSat-2, a thermal imaging satellite currently orbiting the Earth. HotSat-2 can monitor everything from industrial operations to heat patterns in large cities, and it can even detect movement inside buildings. This raises some serious questions about privacy.

HotSat-2 doesn't work like an X-ray camera that can see through walls, or even everyday tech that can track your activity. But the technology it utilizes has reportedly been used for intelligence missions, including monitoring a nuclear facility in North Korea. SatVu's capabilities are so precise that the company says its thermal imagery can determine whether specific equipment, such as pumps at a nuclear reactor, is operating or inactive based on its heat signature. The company has also demonstrated the tech's capability through previous imagery at other locations, including Japan's Yokosuka Naval Base, the Ruwais Refinery in the United Arab Emirates, and the Albuquerque International Airport in the U.S.

US Weighs Removing Steering Wheel Requirement for Driverless Cars

[...] "If you're developing a vehicle that is designed never to be driven by a human operator, does it make any sense to require manual control for the vehicle?" Morrison said. "I think the answer is pretty clear there."

Some self-driving cars, such as models intended for ridesharing fleets from companies like Uber and Tesla, are already steering in that direction, since they aren't designed for human driving. Some, such as the cars used by Waymo, can be taken over by remote human drivers.

Removing brake pedals and steering wheels, however, would mean that a human could not take over if an autonomous car stalls or a dangerous situation arises that requires intervention.

[...] In the CNBC interview, Morrison also discussed a letter sent to autonomous car makers about incidents in which those vehicles have stalled or been slow to move out of the way of emergency responders.

Scientist models way to make sure no one's violating the ban on nuclear weapons in space

One scientist has produced a detailed model which proposes a way to verify that no government or rogue actors are secretly hiding nuclear weapons in the Earth's orbit.

Currently, international laws prevent the use of nuclear weapons in orbit, but it also presents a problem.

International space law was created by the Outer Space Treaty, which was drafted in 1966 and has been ratified by 117 nations, including the USA, China, and Russia, since then. It explicitly bans nuclear weapons from being used in space, which is reassuring, because a nuclear explosion launched from an orbiting object could destroy most of the satellites in low Earth orbit, creating havoc with vital satellite communications, imaging and weather forecasting, to say the least.

[...] Danagoulian's modeling showed calculations suggesting a CubeSat made of commercially available equipment weighing up to 18kg could detect the tell-tale signals emitted by nuclear weapons in space. Such a satellite could identify a thermonuclear weapon at a distance of 4 km after around a week of observations, the study found.

Utility Companies Want To Take Control Of Your Home's Smart Thermostat

One of the uncomfortable elements of a more digitized, interconnected world is that outside parties can access your devices remotely. This is even true for those with smart thermostats, with perks like convenient HVAC adjustment over Wi-Fi and, in some cases, a lower energy bill, which can come with an unusual reality. There are now multiple proposals coming forward, on top of existing agreements between individuals and utility companies, that could grant utility companies remote access to residents' smart thermostats. Of course, these agreements don't come out of nowhere, and so far they're not mandatory.

The idea behind giving utility companies access to thermostats stems from efforts to reduce strain on power grids across the United States. Remote access allows companies to strategically tweak usage at specific points during the day and night, and when grid strain approaches critical levels. In Arizona, three different utilities have pushed for such agreements, seeking to avoid grid overload and blackouts during extreme heat events. Meanwhile, Ohio is pushing to formally authorize these voluntary demand response programs via House Bill 427. These are just two of many state-specific energy-conserving initiatives in play at this point.

[...] While many have already worked with utility companies to grant occasional access to their thermostats, many aren't so keen on the idea. The main concern is that this is an example of corporate overreach and that companies shouldn't be allowed to change how individual homes set their temperatures. Could this lead to higher billing? Or even dangerous in-home temperatures during winter and summer? Some online have even voiced their extreme dislike of these deals, desiring ways to hack into their smart thermostat to prevent any unwanted entity from making remote changes.

New Horizons Pluto probe just woke itself up after 321 days of hibernation

NASA's New Horizons probe has woken itself up after 321 days of hibernation.

The aerospace agency sent commands to the probe last July, instructing it to commence hibernation on August 7 and then resume activity in July 2026.

On June 23, NASA checked to see if New Horizons had obeyed the instruction to wake up and was pleased to find it was online again.

New Horizons' main job was to make our first ever visit to Pluto, which it accomplished in 2015, before zipping off to visit a Kuiper Belt object named Arrokoth in 2019.

What, did someone get some bad news during their IPO process or something?

Investment bankers might be next in line to be rendered obsolete by artificial intelligence if OpenAI's latest push into the financial space is any indication. 

The House of Altman on Wednesday opened up a new position for an investment banking expert, whose responsibilities include making ChatGPT and its AI relations better at handling the complexities of major financial transactions like mergers, acquisitions, fundraising, and other high-value, high-stakes financial ventures.

The job notice mentions that investment banking is one of the most demanding knowledge work tasks around due to all the things bankers have to consider, and it seems to be hoping AI can serve as an assistant for some of Wall Street's heaviest hitters. 

"We are looking for a Subject Matter Expert in Investment Banking to help define what excellent AI-assisted banking work looks like and turn that standard into better models and products," OpenAI said in the posting. "You will use that expertise to design realistic tasks and evaluations, create and assess high-quality reference work, diagnose model failures, and help our technical teams improve model behavior and product experiences."

OpenAI further describes the position as defining "the quality bar for AI-assisted investment banking," making it seem suspiciously like the ChatGPT maker isn't satisfied to keep its financial insights confined to the personal bank accounts of its individual users. 

The company announced in May that it was adding connectors for personal financial accounts to be integrated into ChatGPT, giving AI direct access to bank records and other financial data. The feature was rolled out generally to ChatGPT Plus and Pro users at the end of June. 

Now, it seems, OpenAI wants ChatGPT to help i-bankers, with the aforementioned "quality bar" touching things like research, analysis, valuation, modeling, diligence, transaction execution, and handling client materials. OpenAI apparently also wants its subject matter expert to help translate banking workflows into "representative evaluation tasks" that would allow AI to handle turning investment ideas into success, and generally "improve model performance on financial work." 

Improvement would probably be warranted, given AI's tendency to still get things wrong on the regular. OpenAI even admitted last year that its models are programmed to make things up rather than admitting they don't know something. That's not exactly a comforting thought to businesses considering trusting an AI to provide advice on multi-billion-dollar deals.

OpenAI may have the hubris to believe an LLM that's frequently wrong and makes up facts can substitute for the subject matter expertise of an army of investment bankers, or it could just be unhappy with the investment banking world. The company, now in the process of going public, has slipped from being the darling of the AI world to playing second fiddle to Anthropic, which actually beat the ChatGPT lab to filing its own IPO documents. 

Some in the financial industry, meanwhile, are expressing concerns that the AI bubble OpenAI helped to inflate could pop, potentially taking the global economy with it. It's no wonder, then, that the company is looking to train its own investment banking AI that can present more favorable opinions of the AI space than skittish financial heavyweights.

In exchange for teaching an AI to do their own job, OpenAI's future investment banking expert will be offered as much as $205K a year, plus equity. OpenAI didn't respond to questions for this story.

https://arstechnica.com/space/2026/07/china-recovered-its-first-reusable-rocket-and-showed-a-new-way-to-do-it/

China's sprawling state-owned rocket developer, maker of the country's Long March rocket family, announced it recovered a reusable orbital-class booster for the first time Friday in the South China Sea.

The milestone mission began with the liftoff of a Long March 10B rocket from the Wenchang Commercial Space Launch Site on Hainan Island, China's southernmost province. Powered by seven kerosene-fueled engines, the approximately 209-foot-tall (63.6-meter) rocket took off at 12:15 am EDT (04:15 UTC), or 12:15 pm local time at the seaside spaceport at Wenchang.

About 10 minutes later, the Long March 10B booster descended from space and guided itself into a four-legged frame affixed to an offshore vessel. Tensioned cables stretched over the ship in a grid pattern captured the rocket as it shut down its landing engines, leaving the smoldering booster hanging in midair. The rocket's upper stage continued into orbit and deployed a payload known only as CX-26. Chinese officials hailed the flight as a "complete success."

"A historic day in China's space program!" wrote Mao Ning, a spokesperson for the Chinese Foreign Ministry, on X. "China's Long March 10B has successfully completed its maiden flight—and recovered its first stage via a sea-based net. This marks the country's first-ever controlled rocket recovery. A major leap toward reusable launch capabilities."

The landing on Friday makes the China Aerospace Science and Technology Corporation (CASC) and its subsidiary, the China Academy of Launch Vehicle Technology (CALT), the third enterprise to accomplish this feat. SpaceX did it with its Falcon 9 rocket in 2015 and with its Starship/Super Heavy booster in 2024. Blue Origin landed its New Glenn booster on an offshore platform for the first time last November.

SpaceX and Blue Origin use propulsive landings to return their Falcon 9 and New Glenn boosters to offshore platforms or onshore landing pads. With Starship, SpaceX pioneered a new method of catching the rocket's reusable booster back at its launch pad using mechanical arms mounted to the launch tower.

The Long March 10B employs a different approach for recovery, combining an offshore vessel floating downrange with the catch technique somewhat like what SpaceX uses for Starship. Catching the rocket in this way reduces the effect of reuse on payload capacity. The Long March 10B doesn't have to carry the extra mass of landing legs, and recovering it downrange reduces how much fuel the rocket must consume during its descent.

In a statement, CASC said the Long March 10B test flight "validated key core technologies" for a reusable launch architecture, such as multiple engine restarts with high-altitude ignition, high-precision navigation and control, and the first capture and recovery using a net system on a sea-based platform.

Friday's launch was the first flight of the Long March 10B, a medium-lift rocket with a payload capacity of approximately 16 metric tons (35,000 pounds) to low-Earth orbit. This is slightly less than the lift capacity of SpaceX's Falcon 9. The Long March 10B has two stages, with seven YF-100K engines on the booster consuming kerosene and liquid oxygen, and a single methane-fueled YF-219 engine on the second stage.

"Moving forward, the Long March 10B development team will continue to optimize the vehicle's performance and accelerate the iterative upgrading of reusable rocket technologies," CASC said. "The first stage reuse flight test is expected to be completed by the end of this year."

The Long March 10B is similar to China's Long March 10A rocket, which is still awaiting its first full-scale test flight. The Long March 10A has the same first stage booster as the Long March 10B, but a different upper stage and a payload fairing to accommodate cargo and satellites. The Long March 10A, on the other hand, is designed for future crew launches to China's Tiangong space station using the country's new human-rated spaceship, the Mengzhou, replacing China's Shenzhou crew capsule and the Long March 2F rocket used to power it into orbit.

A heavier configuration, known simply as the Long March 10, is a key part of China's Moon program. This more powerful rocket will combine three Long March 10 first stage boosters—each reusable—together to generate more thrust at liftoff. A second stage and third stage will propel Chinese astronauts and their lunar landers toward the Moon. The Chinese government says it aims to land its citizens on the Moon by 2030. Friday's launch was a small step toward that goal.

China launched a scaled-down version of the Long March 10A rocket in February with a prototype of the Mengzhou capsule to test the spacecraft's launch abort system, which would trigger to whisk crew members away from a failing rocket. The Mengzhou test went well, and remarkably, the Long March 10A continued flying after the capsule fired away from the booster, eventually coming back to Earth for a controlled splashdown at sea. The Long March 10B took this achievement a step further with a midair catch.

Multiple commercial and government-backed Chinese rocket companies are trying to level the playing field with the United States. China is the world's second-largest spacefaring nation, but US companies, dominated by SpaceX, are launching payloads into orbit about twice as often as Chinese rockets. SpaceX's blistering launch cadence is made possible by the partially reusable Falcon 9, something Blue Origin and Chinese companies are seeking to emulate.

US military officials have identified China's advancements in reusable rocketry as a key to unlocking the country's ability to potentially threaten US assets in space. "I'm concerned about when the Chinese figure out how to do reusable lift that allows them to put more capability on orbit at a quicker cadence than currently exists," said Maj. Gen. Brian Sidari, the Space Force's deputy chief of space operations for intelligence, at a conference last year.

SpaceX has used the Falcon 9's rapid-fire launch cadence to deploy more than 12,000 satellites for its commercial Starlink Internet network. Starlink has spawned several spinoffs for the US military, including a secure communications network called Starshield, a constellation of spy satellites based on the Starlink design. More recently, SpaceX has won contracts to provide the Space Force with a new Space Data Network and support an emerging capability using satellites to identify moving targets on the ground and in the air.

All of this would give US forces an advantage in any future conflict with China, which is still in the early stages of launching its own versions of Starlink. China's mastery of rocket reuse would significantly expand the country's launch capacity, accelerating its ability to close the gap.

"Clearly, they admire the work that's being done by SpaceX and are trying to replicate it, and at the same time take it away from the United States if it ever came to it," said Charles Galbreath, a retired US Space Force colonel and director and senior resident fellow for space studies at the Mitchell Institute think tank's Spacepower Advantage Center of Excellence.

"We'll see what happens next," Galbreath told Ars. "Are they able to rapidly turn and increase their launch rate as a result of this potential reuse? What impact will that have on their ability to field an operational architecture of satellites?"

Two Chinese rocket companies have already tried to recover their rockets after launching from one of China's inland spaceports. The first was LandSpace, a privately funded firm that debuted its medium-class Zhuque-3 rocket in December. The rocket reached orbit, but the booster crashed near the landing zone in the Gobi Desert at high speed. A few weeks later, another one of China's state-owned rocket builders successfully launched the first Long March 12A rocket, but the booster again lost control on descent and could not be recovered.

The next flight of the Zhuque-3 rocket could happen later this month or in August, with LandSpace again expected to attempt to land the booster downrange. Other Chinese rockets that could soon achieve reusability include Space Pioneer's Tianlong-3, China Commercial Rocket Co.'s Long March 12B, CAS Space's Kinetica-2, i-Space's Hyperbola-3, and Galactic Energy's Pallas-1. Further into the future, China aims to debut a huge new reusable rocket on the scale of Starship named the Long March 9.

In the United States, there are SpaceX's Falcon 9, Falcon Heavy, and Starship, along with Blue Origin's New Glenn rocket. Rocket Lab is aiming to launch its first medium-lift Neutron rocket with a reusable booster by the end of the year. Relativity Space is developing a partially reusable heavy-lifter named Terran R, and Firefly Aerospace is partnering with Northrop Grumman on the Eclipse rocket, which officials say will eventually have a recoverable and reusable first stage. Stoke Space has the bolder ambition of a fully reusable rocket called Nova.

Several European companies also plan to test reusable rocket technology, but their vehicles are not as mature as many of the US and Chinese rockets. Rocket builders in India, Japan, and Russia have reuse in their roadmaps, with varying degrees of realism.

The proliferation of Chinese rocket companies, scattered across four land-based spaceports and multiple ocean-going launch platforms, should set up China to quickly ramp up its launch cadence.

"It probably won't be but a few years before they're able to achieve a much higher launch cadence," Galbreath said. "They also have more launch sites than the United States currently, so if you couple their number of sites with reusability, they could surpass us in terms of launch rate, which in and of itself is more of a pride thing. But it's the capability that's being launched as a result of that that could actually have a significant impact on our competition, and if we got to it, a conflict.

"There's nothing wrong with competition as long as it's peaceful," Galbreath said. "That can drive innovation, but I'm concerned that the historic example of Chinese behavior has not always remained peaceful. So, we have to look at everything they do carefully. On the one hand, they're competing with SpaceX, but we know that because of the way China has organized its military, its space capabilities, all under military control, that there is significant utility that their armed forces will receive from this race."

https://www.slashgear.com/2208743/why-navy-submarine-propeller-designs-are-kept-secret/

Militaries around the world frequently release photographs and videos of submarines entering or leaving port. Yet if you look closely at them, one detail is typically missing: the propeller.

[...] At first glance, a submarine propeller may not seem all that different from one found on a commercial ship. However, every aspect of its design is carefully engineered to help the vessel move as quietly as possible through the water. Put another way, naval propeller design places stealth above propeller efficiency. Stealth is achieved by minimizing cavitation, which is the sudden implosion of vapor bubbles when the speed of propeller blades drops local water pressure below its vapor point, creating an acoustic signature that can be tracked by the enemy. Details such as the number of blades, their shape, curvature, pitch, and even the precision with which they are manufactured all influence the amount of noise and vibration produced as the submarine travels beneath the surface. While those differences may appear subtle to the casual observer, they can have a significant impact on a submarine's ability to remain hidden during operations.

https://www.tomshardware.com/tech-industry/drones/electric-drone-breaks-world-air-speed-record-at-434-mph-designed-for-anti-aircraft-interceptor-roles-german-firm-convincingly-smashed-the-official-409-mph-record-hopes-to-get-stamp-of-approval-from-guinness-soon

According to the official press release, the Apex Recordhunter drone was developed over the last year and serves as a technology demonstrator for next-gen electrically powered drones. Tellingly, Ukrainian engineers are also working on this project under the auspices of WIY Drones, a branch of Quantum Systems. It will also be attempting record-breaking speed challenges in Ukraine, as the Apex Recordhunter is being assessed for future interceptor drone programs.

So, we might have a flurry of new drone speed records on the way, and it wouldn’t be a great surprise if the Apex Recordhunter drone pushes past the 700 km/h (435 mph) milestone.

Like with the Apex Recordhunter drone, the Blackbird speed record remains unofficial, as they haven’t had a verification that requires a certified independent observer, verified measurement equipment, documentation including a submission, followed by a controlled two-way run.

At the same time, WIY Drones, part of the Quantum Systems Group, is targeting two official Ukrainian speed records during planned testing expected next week.

  • STRILA Interceptor – Highest speed achieved by an FPV interceptor drone carrying a 0.5 kg payload.
  • SPYS – Highest speed achieved by an anti-aircraft class FPV interceptor drone.

These initiatives reflect WIY's continued development of high-performance interceptor systems designed to counter increasingly fast and maneuverable aerial threats, building on the company's operational experience and its growing role within the Quantum Systems Group.

Mainstream news sources note that Gulf States are rapidly eating through their air defense supplies. Contrasts are made between the costs of dispatching Ukrainian drone interceptors ($1,000 to $2,000) vs a Patriot missile (~$4 million). It isn't all about the cost, though. Supplies of Patriot missiles are also more constrained. Some commentators note that more Patriot missiles have been fired during the Iran war than Ukraine has been supplied during the last four years.

Another thing in the Ukrainian interceptor drone's favor is that it can be launched and controlled by one person. Patriot missiles need a launcher system and three soldiers for a one-off launch, but around 90 personnel for full sustained operation and maintenance.
