SpaceX’s first Starlink V2 satellites spotted at Starbase
On Monday, SpaceX was spotted loading some of the first Starlink V2 satellite prototypes into a custom mechanism designed to refill Starship’s magazine-like payload bay.
While it’s not the first time SpaceX has used the dispenser, the photos captured by photographer Kevin Randolph are the first to clearly show real prototypes of the next generation of Starlink satellites. According to CEO Elon Musk, those Starlink Gen2 or V2 satellites will be “at least 5 times better”, “an order of magnitude more capable,” and about four times heavier than current (V1.5) Starlink satellites.
The potential of the new satellite bus design paired with Starship’s massive fairing and lift capacity could dramatically improve the viability and cost-effectiveness of SpaceX’s Starlink constellation. First, though, the company needs to launch and qualify prototypes of the new satellite design and verify that all associated ground support equipment works as expected.
Study finds widespread false memories of logos and characters, including Mr. Monopoly and Pikachu
If you had to describe Rich Uncle Pennybags—the Monopoly mascot—would you mention his top hat? His mustache? How about his monocle?
The face of the famous board game has, in reality, never worn a monocle. Yet, many people confidently list the accessory when recalling his features—an example of a phenomenon of false visual memories.
A forthcoming paper by University of Chicago scholars, currently available in preprint, found that people have consistent, confident, and widespread false memories of famous icons—also known as the Visual Mandela Effect. Co-authored by University of Chicago scholars, the paper is the first scientific study of the internet phenomenon.

Roel van DijnenI did not realize that India still has such a small economy, smaller then Germany and UK 😳
Eric KlienAdmin.
Roel van Dijnen In related news, India has so far stopped Tesla and Starlink from operating in their country. Governments can, and often do, screw up their economy.
Roel van DijnenEric Klien The screwing up part is rather subjective, imagine the effect on earth when countries like India and Nigeria will adopt the same luxurious lifestyle that we have. But then again, Tesla and Starlink are trying to be part of the solution for that also 😉
Freya WildeRoel van Dijnen even if they did adopt a more luxurious lifestyle, who is to say it would be the same. Wouldn’t that be up to the people there? I have no idea how any country will ultimately act. And I have zero right to guess and interfere. No one doe… See more.
Roel van DijnenFreya Wilde I’m not claiming to have any right to intervene (forcefully) and I sure hope better more sustainable ways of having a great lifestyle will be upon us, preferably sooner rather than later!
SpaceX’s Starship Booster 7 gone for repair after explosion, JWST First Images, CRS-25, Vega C

Quite the inspirational week this one with the complete set of JWST First Images. Loads of Starship and Starbase news. Last week I mentioned that it was fire time for Starbase, and…WOW… I was not wrong there. SpaceX’s Starship Booster 7 has gone for repair after explosion. Falcon 9 launches for both Starlink and finally CRS-25. We also had the very first launch of Vega C. Rocket Lab firing off another Electron, and more. So enough of this intro. Let’s crack on with it!

Researchers propose dual-plating strategy to rapidly construct microbatteries
High-performance, micro-sized electrochemical energy storage devices are essential for future miniaturized electronic devices, such as smart medical implants, wireless sensors, and the Internet of Things. Microbatteries (MBs) typically show higher energy density and more stable voltage output than micro-supercapacitors.
However, current MBs involve tedious construction procedures and unsatisfactory electrochemical performance. In addition, no methods exist to construct or manipulate a liquid microelectrode.
A joint research team led by Prof. Qu Liangti from Tsinghua University, Prof. Zhang Zhipan from the Beijing Institute of Technology, and Prof. Liu Feng from the Institute of Mechanics of the Chinese Academy of Sciences (IMCAS) recently proposed a dual-plating strategy to rapidly construct new zinc–bromine microbatteries (Zn–Br2 MBs) with ultrahigh areal energy density and polarity-switchable functionality.
Physicists Find The ‘Missing Link’ That Could Provide Quantum Internet Technology
Before quantum computers and quantum networks can fulfil their huge potential, scientists have got several difficult problems to overcome – but a new study outlines a potential solution to one of these problems.
As we’ve seen in recent research, the silicon material that our existing classical computing components are made out of has shown potential for storing quantum bits, too.
These quantum bits – or qubits – are key to next-level quantum computing performance, and they come in a variety of types.
A New Attack Can Unmask Anonymous Users on Any Major Browser
When you visit a website, the page can capture your IP address, but this doesn’t necessarily give the site owner enough information to individually identify you. Instead, the hack analyzes subtle features of a potential target’s browser activity to determine whether they are logged into an account for an array of services, from YouTube and Dropbox to Twitter, Facebook, TikTok, and more. Plus the attacks work against every major browser, including the anonymity-focused Tor Browser.
“If you’re an average internet user, you may not think too much about your privacy when you visit a random website,” says Reza Curtmola, one of the study authors and a computer science professor at NJIT. “But there are certain categories of internet users who may be more significantly impacted by this, like people who organize and participate in political protest, journalists, and people who network with fellow members of their minority group. And what makes these types of attacks dangerous is they’re very stealthy. You just visit the website and you have no idea that you’ve been exposed.”
The risk that government-backed hackers and cyber-arms dealers will attempt to de-anonymize web users isn’t just theoretical. Researchers have documented a number of techniques used in the wild and have witnessed situations in which attackers identified individual users, though it wasn’t clear how.
Researchers find the missing photonic link to enable an all-silicon quantum internet
Researchers at Simon Fraser University have made a crucial breakthrough in the development of quantum technology.
Their research, published in Nature today, describes their observations of more than 150,000 silicon “T center” photon-spin qubits, an important milestone that unlocks immediate opportunities to construct massively scalable quantum computers and the quantum internet that will connect them.
Quantum computing has enormous potential to provide computing power well beyond the capabilities of today’s supercomputers, which could enable advances in many other fields, including chemistry, materials science, medicine and cybersecurity.
