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.

A larger five by five array of detectors could produce sharper maps and complete the work more quickly.
Mapping The Moon's ChemistryThe 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 DifficultEarlier 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 OrbitTo 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 MapThe 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 GeologyIf 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.

Tyler Durden Mon, 06/08/2026 - 22:35Over 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!"...
AOC : "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?

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

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 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.
