Here is the news. A collaborative team of Chinese and French researchers has successfully completed a mission to measure the distribution of radon gas and polonium on the moon, employing the French payload aboard China's Chang 'e 6 lunar probe for the purpose.
That is according to the Institute of Geology and geophysics under the Chinese Academy of Sciences.
The French payload is capable of measuring both radon gas and its decay products on the lunar surface, as well as charged particles in the space environment.
Its scientific goals include exploring the origin and dynamics of the lunar atmosphere, the thermal and physical properties of lunar soil, and the movement of lunar surface dust.
He Hui Yu, co -chief scientist of The Payload from the Institute of Geology and Geophysics, the Chang 'e -6 radon gas detector had been exposed to the Earth's atmosphere for several months before launch.
It was first activated on May 6 during the lunar orbit cruise period, some 320 ,000 kilometers from Earth, and worked, for about ten hours, to measure the background noise of the space environment and natural pollution on the lunar surface on May 17, following the historic solar storms that occurred between May 10 and 11.
length. The instrument was powered on again.
It performed measurements in lunar orbit for a total of 32 hours.
Based on the data beamed back to Earth, the team confirmed that all 16 detectors of the radon measurement instrument were functioning properly, and obtained data the flux of charged particles in the solar wind and their decay over time.
The lunar shielding effect on these particle fluxes was also observed.
That is according to Li Jiannan, Chinese technical head from the Institute of Geology and Geophysics.
The instrument was restarted on May 23.
It proceeded to conduct orbital measurements of radon and polonium distribution on the for 111 hours.
On June 2nd, shortly after the Chang 'e 6 lunar probe landed at the designated landing area in the South Pole Aitkin Basin on the far side of the moon, the radon gas detector began its measurements of the lunar surface.
on June 4, when the ascender of Chang 'e 6 took off from the moon with samples, the detector completed its detection mission and became a permanent resident on the far side of the Moon, noting that the collaborative team worked together on the operation of the Radon gas detector at the National Astronomical Observatories of China.
He said that this marked the first collaboration between China and France in the field of deep space exploration contributing to the success of the mission.
China's Chang 'e -6 spacecraft was launched into orbit on May 3, carrying four international payloads from the European Space Agency, France, Italy, and Pakistan.
The country's Chang 'e 7 lunar exploration mission will carry six international scientific instruments and the Chang 'e 8 will offer 200 kilograms of international payload capacity and has garnered over 30 applications.

Chinese researchers have created a novel method to produce crystals that can greatly improve the controllability of their structures.
That is according to a research article published in the journal Science.
Crystals are indispensable key materials in modern computers, communications, aviation production, and laser technology.
The new method of crystal production is expected to enhance the computing power of chips, and serve a new generation of electronic integrated circuits and photonic integrated circuits.
The traditional method of producing large -size crystals is to layer atoms bottom -up on the surface of small crystal particles.
This method is limited by the necessity for strict screening of the type and arrangement of atoms to accumulate and form crystals.
And when the number of atoms increases the atomic arrangement gradually becomes uncontrolled, and impurities and defects are gradually accumulated, affecting both the purity and quality of the crystal.
That is according to Liu Caihui, professor at the School of Physics of Peking University, who led the research team.
They developed a new method to accurately control the atomic arrangement, enabling the crystal growth rate to speed up to 50 layers per minute, with a number of layers reaching up to 15 ,000.
The atomic arrangement of each layer is completely parallel and precisely controllable which effectively avoids the accumulation of defects in crystal growth and improves the controllability of the structure.
The researchers have applied this new method to produce seven types of two -dimensional crystals.
Liu noted that the monolayer thickness of the two -dimensional crystals is only 0 .7 nanometers and, when they are used in the transistors of integrated circuits, the integration of chips can be significantly improved.
Liu said that the density of transistors can be greatly increased on a fingernail sized chip to provide more computing power.
Such crystals can also be used for the infrared frequency conversion of light, which is expected to promote the application of ultra thin optical chips.

Shanghai's cruise ports have seen more than 180 entries and exits, made by International Cruise Liners in the first half of this year, with more than 840 ,000 people on board that is according to Shanghai border inspection authorities.
Furthermore, more than 45 ,000 entries and exits were made by foreign visitors at the Shanghai cruise ports in the first half of this year with 18 ,000 inbound visits facilitated by various visa -free policies.
Meanwhile, five international cruise liners used Shanghai as their home port.
them. China's first domestically built large cruise ship, Adora Magic City, embarked on its maiden voyage at the beginning of this year, and has since completed more than forty collected resurgence of inbound tourism.
China has implemented a visa -free policy for ordinary passport holders from over a dozen countries, and allowed visa -free entry for foreign tourist groups aboard cruise ships at all cruise ship ports along the country's coastline.

The Giant Panda College under China West Normal University, in southwest China's Sichuan province—known as the home town of Giant Pandas—is set to enroll fifty undergraduates this autumn, majoring in wildlife and nature reserve management.
The college, established last September by the Provincial Forestry and Grassland Administration, Is China's first college to feature giant panda studies?
China West Normal University has a long standing focus on the ecological protection of rare, wild animal and plant resources in southwest China's mountains.
It is the earliest, longest lasting and most influential university to conduct research in the field of wild, giant panda ecology.
The college has signed cooperation agreements with Chengdu Research Base of Giant Panda Breeding and several national nature reserves.
Wei Wei, a teacher at the college, said that during their college studies, students have the opportunity to pursue internships, participating in work related to giant panda protection, conservation, breeding and disease prevention and control.
What a beautiful Jasmine flower!
Sweet smelling, beautiful stems, full of buds, fragrant and white, everyone praises it.
This household tune is called Mo Li Hua, the Jasmin flower, and you might have heard it before.
In 1982, the Chinese folk song was recommended in musical textbooks of the Asia Pacific Region by UNESCO.
It appears in the Italian opera Turandotte, the closing ceremony of the 2004 Athens Olympics and the medal ceremonies of the 2008 Beijing Olympics, or testify to its immense popularity and status.
But you might not be as familiar with the intriguing stories behind the true star of this song, the Jasmine Flower, and its extraordinary presence in Chinese culture.
just as the song describes, More Li Hua, or the Jasmine Flower, is typically pure white, with a delightfully fresh fragrance.
The small and thick petals have a waxy sheen, giving them jade -like beauty.
Renowned for its pure white petals and refreshing scent, the Jasmine flower holds various cultural meanings in Chinese tradition, symbolising elegance, humility and sincere love.
And here I have an intriguing tale to share, one that perfectly captures the essence of this cherished flower.
In ancient times there lived a humble tea farmer with with two sons.
One day the farmer came home, with a bundle of seedlings, of an unfamiliar plant.
Without much thought the farmer planted them along the edge of his elder son's tea -field.
As the seasons turned, a year passed, and, to everyone's surprise, clusters of fragrant little white flowers bloomed, filling the elder son's tea garden with their delightful scent.
One day, while picking tea, the elder son was inspired by the pleasant aroma, coming up with the idea of mixing these fragrant flowers with his tea leaves, carefully infusing using the tea leaves with the sweet fragrance.
He then removed the flowers and brewed himself a cup, which turned out to be amazing with the lingering fragrance.
As expected, the fragrant tea sold exceptionally well and the elder son soon became a wealthy the man.
After hearing the news, his younger brother felt a sense of injustice and demanded a share of the prophets, arguing that he would have prospered, too, if the flower had been planted in his field.
Without hesitation, the elder brother turned down the request.
he asked. To seek the justice he wanted, the younger brother sought out a venerable elder in the village and recounted the entire tale.
After hearing the story, the elder proposed a wise solution that the two brothers should work together to expand the business, noting that with the fragrant tea selling so well, if the two young men looked beyond the immediate gains, they could join hands to achieve greater success.
To reinforce this lesson of brotherhood, the wise man named the little white flower as is, more li hua', with more meaning the end, and li representing profit.
The two words are combined to serve as a reminder that the two young men, instead of focusing so much on personal gain, should consider the bigger picture, and put individual profit to an end.
Following the elders advice the brothers united their efforts and their business flourished exponentially.
Throughout history the Jasmine Flower has been adorned in Chinese culture for its auspicious meanings poets and lighters, have long been inspired to compose verses and prose, extolling its purity and beauty.
In one case, about eight hundred years ago, the poet Young Won Lee once penned, and, jasmin flowers stand out from the rest, exuding a subtle and rich fragrance.
Even ambergris avoids competing for fragrance, and snowflakes shy away from challenging their beauty, conveying his profound admiration for the flower.
Moreover, the jasmine flower has found wide application in tea -making, perfumery, and medicine throughout history.
In particular, the flower is valued in traditional Chinese medicine, for its ability to treat red and swollen eyes, as well as to alleviate coughs and phlegm.
And, if you visit cities, like Soojou, during summer, when the jasmine flower blooms, you may encounter street vendors selling intricately crafted jasmine flower bracelets.
The tiny blossoms are carefully strung together.
As one strolls through the streets, the enchanting fragrance of jasmine fills the air, offering pedestrians moments of tranquility amidst the bustle of city life.
