Here's the news. China's Communication and Navigation Technology Test Satellites Tiandu 1 and Tiandu 2 have successfully carried out experiments on new technologies such as highly reliable Earth -Moon transmission and routing.
The telemetric data shows that the test project could effectively improve the accuracy of spacecraft in determining the lunar orbit.
The two satellites were sent into space together with the Quechiao -2 relay satellite on March 20.
They later entered their target circumlunar orbits and separated.
On April 8, Tien Du 1 started flying in formation with Tien Du 2 remaining at a distance of about 200 km.
The two satellites operate in normal communication and energy balance.
They laid an important foundation for carrying out a series of communication technology test missions and Tiandu -2 has captured and sent back Earth -Moon group images.
Quizqiao -2, Tien -Du -1 and Tien -Du -2 all use a highly elliptical lunar frozen orbit as their target orbits.
This kind of orbit is stable ensuring the spacecraft travels with minimum trajectory deviation.

A Chinese research team has introduced a novel method to analyze the behaviors of active fast radio bursts in the time -energy domain.
Fast radio bursts are intense pulses of radio emission that last just a few milliseconds.
The origin of these brightest cosmic explosions in radio bands remains unknown.
based on the rich data of China's 500 meter aperture spherical radio telescope or fast for short.
A research team at the Chinese Academy of Sciences proposed a new analysis framework that is able to quantify the randomness of chaotic nature of the bursting events.
The study revealed that the behaviors of fast radio bursts in the time energy domain are fundamentally different from those of common transient physical phenomena such as earthquakes and and solar flares, exhibiting a high degree of randomness like a Brownian motion shedding new light on the origin of the phenomenon.
Lee Dee from the National Astronomical Observatories under the Academy who led the study said that the excellent observation capabilities of the radio telescope combined with innovative analytical methods will enable in -depth study of mysterious burst signals in the universe which is expected to eventually reveal their origin.
The study was published as a cover paper in the journal Science Bulletin.

China has rolled out specific measures to facilitate and encourage trade -ins of consumer goods.
According to an action plan jointly released by the Ministry of Commerce and 13 other government departments, China aims to establish a trade -in mechanism that facilitates the scrapping of used goods in exchange for smart green and low -carbon ones.
To promote the trade -ins of automobiles, subsidies will be given to consumers who scrap high emission passenger cars to buy energy efficient vehicles or new energy vehicles.
The practice of reverse invoicing for second -hand car transactions will be promoted as well as the service model where the old cars can be collected at their doorsteps.
For used home appliances, the plan said that the country will provide financial support to establish recycling systems for renewable resources.
Local governments and home appliance companies are encouraged to offer subsidies or preferential policies for consumers who purchase or trade for green and smart home appliances.
Localities are encouraged to support the upgrading and renovation of old houses to develop age -friendly facilities and promote the consumption of smart household products.

The China National Intellectual Property Administration has announced its decision of joining the Patent Prosecution Highway Improvement Initiative, which involves cooperation between the world's five leading IP offices, namely China, the United States, Europe as well as Japan, and the Republic of Korea.
This initiative is aimed at establishing a more predictable examination cycle.
The administration has vowed this year to realize an average duration of three months from the grant of a Patent Prosecution Highway request to the issuance of a First Office action.
It also aims for an average response time from examiners to applicants of no more than three months.
The Patent Prosecution Highway, or PPH for short, is a fast -track linking patent duties of different countries or regions, allowing patent authorities to share their work to speed up the examination process.
Since the initiation of the first PPH pilot program in November 2011, the China Intellectual property administration has built PPH ties with patent examination authorities from 32 countries or regions.
The five members of the initiative are the world's five leading IP offices known as the IP 5 They together handle about 80 % of the world's patent applications This is special English You've been listening to programs from CGTN radio CGTN radio We invite you to visit us online for more audio, pictures and in -depth reports.

The Premier League has announced that it will introduce a semi -automated system to decide on -tight, off -side decisions for the 2024 -2025 season.
The decision is aimed at ruling out any controversy over the video assistant referee calls, while while also reducing the time needed to make a decision.
The semiautomated system gives a result in around 30 seconds, while the video assistant referee calls can take several minutes, frustrating players and also fans.
Semi -automated technology was used at the 2022 FIFA World Cup in Qatar and is already in use in Italy's Serie A.
It will also be introduced in Spain's La Liga for the coming season.
The Premier League said in a statement that clubs had unanimously agreed to the introduction of semi -automated off -side technology.
The new system will be used for the first time in the Premier League next season and it is anticipated that the technology will be ready to be introduced after one of the autumn international breaks." The statement adds that the technology will provide quicker and consistent placement of the virtual offside line based on optical player tracking and will produce high quality broadcast graphics to ensure an enhanced in -stadium and broadcast experience for supporters.

Archaeologists have discovered more than 80 stone carvings and building components in Longmen Grottoes — a UNESCO World Heritage Site in central China's Henan Province.
According to the Longmen Grato's research institute, the relics were found inside the Leigutai caves during a maintenance and reinforcement work.
It is the first time that archaeologists have found stone carvings inside the cave of Longman Grottoes.
Located at the south end of the Grottoes, Dongshan area, Lei Gu Tai boasts three caves and several small niches on the cliff.
Liu Wei, director of the History and Humanities Research Center of the Institute, said that the unearthed items include a relatively well -preserved Buddha head, which measures 38 centimeters high and 22 centimeters in width, the remains of a bodhisattva statue and fragments of rosettes, among other items.
Based on the comprehensive analysis of the archaeological excavation results of the Lai Gu Tai Caves and the historical documents.
The relics are thought to have been stacked up and embedded in the wall in the mid to late Ming Dynasty and used as materials to repair and reinforce the cave walls in ancient times.
Liu noted that the findings are of great value for the study of the stone carving art in ancient times, the history and culture of lei gu tai caves and the maintenance and reinforcement works back then.
