Tiny X-Ray Telescope Could Unlock The Moon's Hidden Chemistry

Authored by Tokyo Metropolitan University via ScienceDaily,

Researchers at Tokyo Metropolitan University have used simulations to show that a small, newly developed X-ray telescope could help create a chemical map of the entire lunar surface. Such a map would be a major step toward understanding how the Moon formed, changed, and evolved over time.

Their detailed modeling, which included both the telescope detector and a realistic Moon orbiting satellite mission, suggests that one telescope could map five important elements in about two years. A larger five by five array of detectors could produce sharper maps and complete the work more quickly.

Mapping The Moon's Chemistry

The Moon's geological history is still not fully understood. One major reason is that scientists do not yet have a complete geochemical map of the lunar surface. Because researchers cannot simply collect samples from every part of the Moon, they must rely on remote sensing methods.

One of these methods is X-ray fluorescence imaging. In this approach, detectors are pointed at the Moon to capture X-rays emitted by specific elements after they are struck by solar radiation. Those signals can help reveal which elements are present across different regions of the surface.

Why Complete Lunar Maps Are Difficult

Earlier observations from the Apollo and Chandrayaan missions produced useful partial maps, but a full global map is still missing. Creating one is technically difficult for several reasons. Missions have limited time to gather enough sunlight driven X-ray signals, and detectors can degrade during long periods in space.

The problem is especially difficult near the Moon's poles. In these regions, solar X-rays are weaker, which makes it harder to collect the signals needed to identify surface elements.

A Compact X-Ray Telescope For Lunar Orbit

To address these obstacles, a team led by Airi Toida and Prof. Yuichiro Ezoe of Tokyo Metropolitan University has proposed using a compact X-ray telescope on a satellite orbiting the Moon. The telescope would allow wide area observations of the lunar surface during strong solar flares, when the Sun provides more intense X-ray illumination.

Traditional X-ray telescopes are often too large and heavy for this type of mission. By contrast, the team's compact telescope was originally designed for studying Earth's magnetosphere and weighs less than ten kilograms. Its small size could make it practical for long term lunar satellite observations.

The detector has also been tested in radiation conditions far harsher than those expected in lunar orbit. That durability could support robust, wide area, high resolution imaging over an extended mission.

Simulations Show A Path To A Full Moon Map

The researchers then added the telescope's specifications into a numerical simulation to test whether a satellite mission could successfully map the Moon. Assuming 300 solar flares per year and a single telescope aboard a Moon orbiting satellite, the simulation showed that the whole lunar surface could be mapped for five elements - oxygen, iron, magnesium, aluminum, silicon - in two years, using a grid size of 70 x 70 kilometers.

Because the telescope is so compact, the team also examined a satellite carrying a five by five array of telescopes. According to the simulations, this 25 telescope system could reduce the mission time to one year. With two years of operation, it could also map sodium, while improving the grid size to 30 x 30 kilometers.

A New Window Into Lunar Geology

If either mission concept becomes reality, it would produce the first complete map of elemental abundance across the entire Moon. That achievement would give scientists a powerful new tool for studying lunar geology and reconstructing the Moon's long and complex history.

4 In 10 American Adults Report Having 'Mental Health' Problems

Over the past few years, a lot of progress has been made in accepting and understanding mental health problems.

Having long been seen as a sign of weakness, mental health issues in their many varieties and severities have become much less of a taboo.

As Statista's Valentine Fourreau notes, the pandemic, which left many people feel isolated, powerless or overwhelmed, accelerated that trend, as it not only caused a spike in symptoms of anxiety or depression, but also led more people to open up about their problems.

In a Statista survey from 2025-2026, the prevalence of self-reported mental health problems varies greatly across countries, suggesting that people in some countries, e.g. China or Japan, may be more hesitant to open up about mental health or simply less likely to identify certain problems as mental health issues.

As Statista's chart shows, more than 4 in 10 U.S. adults reported that they experienced symptoms of mental health problems, such as stress, anxiety or depression in the 12 months preceding the survey, making an open discourse about mental health issues all the more important.

With that in mind, we give the last word to AOC, who exclaimed over the weekend that "we are not the crazy ones. We are sane!"...

If you have to tell people that you're sane in public, you probably...aren't.

Also, have you seen the Democrat platform policies wishlist?

Chinese Article Warns VPN Use Alone Can Trigger Punishment Under Expanding Censorship Regime

Authored by Michael Zhuang via The Epoch Times,

A widely circulated Chinese social media article warning that internet users can be punished simply for bypassing China's online censorship system has drawn attention to what observers say is an expanding clampdown on access to the global internet.

The article, published June 2 on Chinese social media WeChat and later archived by California-based nonprofit China Digital Times, which tracks China's state censorship, compiled a series of publicly reported cases of suppression on the use of virtual private networks (VPNs).

The cases included fines imposed on users who accessed overseas websites, penalties for selling VPN services, arrests related to the dissemination of overseas political content, and investigations into internet activity dating back several years.

The article challenged a common assumption among Chinese internet users that using VPNs for research, accessing foreign websites, or utilizing overseas artificial intelligence (AI) tools is unlikely to attract official scrutiny as long as no sensitive content is shared.

"But from publicly disclosed cases, VPN use itself has already become a target of the Chinese Communist Party's (CCP) investigation," the article said.

The examples highlighted in the article suggest that the CCP is increasingly focused not only on what users do online, but also on how they access the internet.

One of the most notable cases involved a resident of Ningde, Fujian Province, who was penalized in 2024 for allegedly using a VPN to browse overseas websites in 2020.

According to the article, police reviewed historical internet records and later imposed an administrative penalty, prompting criticism from some legal observers who questioned whether the action complied with China's statutory limitations on administrative punishment.

The case stood out because it appeared to demonstrate the communist regime's ability to revisit years-old internet activity rather than relying solely on real-time monitoring and censorship.

Chinese legal professionals interviewed by The Epoch Times said that the enforcement action raised questions about the scope of retroactive investigations. Under China's Administrative Penalty Law, administrative violations generally cannot be punished if they remain undiscovered for more than two years, although certain exceptions apply.

The article also cited cases involving individuals punished for selling VPN services and users fined solely for establishing unauthorized internet connections, when there was no indication they had distributed overseas information.

The reported cases come amid broader efforts by the CCP to tighten control over cross-border internet access.

Under Chinese regulations, businesses and foreign nationals requiring international connectivity are generally expected to use telecommunications channels approved by the regime, while unauthorized VPNs and proxy services remain subject to censorship.

OpenAI Files Confidentially For IPO, Joining SpaceX and Anthropic In Capitalizing On AI Frenzy

The rush by AI companies to go public before the window closes (i.e., "market conditions" emerge) entered its final lap late on Monday, when OpenAI joined its two mega peers in filing for a blockbuster IPO that could value the ChatGPT creator at more than $1tn as it races rival Anthropic to list its shares publicly, following an imminent offering by SpaceX.

OpenAI said it had confidentially submitted a draft IPO prospectus to the US Securities and Exchange Commission, formally kicking off the process for one of the year’s most hotly anticipated debuts. The company is also planning to launch a tender sale of its shares to provide liquidity to employees in the coming weeks, before the company goes public, Bloomberg reported. Why employees would want to sell shares ahead of an IPO is not exactly clear, unless they fear the market reaction to the public offering would disappoint. 

OpenAI’s listing announcement comes days before SpaceX is set to IPO in a deal that could raise a record $86bn and value Elon Musk’s rockets-to-AI conglomerate at $1.78tn. Anthropic, the startup behind the chatbot Claude, said last week that it had filed confidentially for an IPO of its own. The company soared to a $965 billion valuation in its latest private funding round - above OpenAI’s for the first time - as its revenue surged.

The three Wall Street listings comes at a time of unbridled euphoria among investors over AI, which has helped propel US stocks to a series of record highs but also prompted worries that markets are overheating. Last week, Goldman published a note seeking to preempt the big question: "Can Markets Absorb Massive Stock Supply From Coming Mega IPOs Without A Crash:" While Goldman did not express concerns about the coming flood of stock supply (its argument is that demand will more than offset the flood of new shares), the bank which is also a lead underwriter for both SpaceX and Anthropic calculated that recent and upcoming IPOs will result in roughly $500 billion of additional unlocked shares available to sell in 2026 and likely a larger quantity in 2027 as insiders sell and distribute their stakes to public (mostly retail) shareholders. The bank expects the majority of potential equity supply from the current pipeline of IPOs will become free float in 2027. 

OpenAI’s IPO - which also comes at a time when CEO Sam Altman has floated handing out shares to US taxpayers ostensibly in hopes that such an action would lead to a government backstop and/or bailout if and when the AI cycle turns - will mark a test of investors’ appetite for a company posting booming revenue growth but also staggering losses that are forecast to continue for many years as the company spends vast sums on data centres and other infrastructure: its funding commitments to hyperscalar companies are well north of $1 trillion and unless the company manages to dramatically boost its revenue growth it will find itself woefully undercapitalized in coming years. Hence the IPO, as well as a bevy of private credit deals which mask the company's true debt exposure. 

OpenAI has been investing heavily in AI research to compete with rivals including Google and Anthropic, as well as to expand the computing capacity needed to serve ChatGPT’s 900mn users. In February, the company told investors it was planning to spend about $600 billion on AI infrastructure by 2030.

It said in a statement on Monday that it had not “decided on timing yet; it may be a while because there are things we want to do that are likely easier as a private company”.

“But it’s a complicated set of trade-offs and this gives us the option to go public sooner if that ends up being best,” it added.

A public debut in 2026 would also pit Altman squarely against Elon Musk on a different plane than the failed lawsuit against OpenAI and its CEO. SpaceX, Musk’s rocket, satellite and AI firm, is targeting an IPO at a valuation of roughly $1.8 trillion on Thursday, which would immediately make it one of the world’s most valuable public companies.

As an indication of the staggering demand for AI exposure, OpenAI has already dwarfed even SpaceX’s IPO in a single funding round. The company completed a deal to raise $122 billion from investors at an $852 billion valuation.

The ChatGPT maker also planned to launch an employee share sale ahead of going public at its current $852bn price tag, according to people familiar with the matter. One said OpenAI’s decision to announce its confidential filing was intended to give employees who were considering selling shares “transparency” about the upcoming IPO.

US tech groups often file IPO paperwork privately, keeping their financial figures out of the public eye while the SEC reviews documents. That allows start-ups to gauge investor demand, make revisions and sometimes scrap IPO plans without broader scrutiny.

The San Francisco-based company’s move to progress its listing plans received a boost after a California court last month threw out Musk’s legal case against OpenAI and its chief Sam Altman. 

A public debut in 2026 would also pit Altman squarely against Elon Musk on a different plane than the failed lawsuit against OpenAI and its CEO. SpaceX, Musk’s rocket, satellite and AI firm, is targeting an IPO at a valuation of roughly $1.8 trillion on Thursday, which would immediately make it one of the world’s most valuable public companies.

OpenAI had been working with bankers at Goldman Sachs and Morgan Stanley and lawyers at Cooley for the past few months, people familiar with its preparations previously told the FT. Monday’s filing sets OpenAI on a path to start trading as early as the autumn, they said.

It is already one of the world’s most valuable private companies, after closing a record funding round of up to $122bn in March. As part of that deal it raised $3bn from retail investors, who will be given a wider opportunity to invest in the start-up when it becomes publicly traded.
