A | (ECNS) -- China aims to build more than 100 million metric tons of annual coal production reserve capacity by 2030, according to the 15th Five-Year Plan for Coal Industry Development, jointly released by the National Development and Reform Commission (NDRC) and the National Energy Administration (NEA) on Monday. By 2030, China's capacity to ensure secure coal production and supply is expected to be further strengthened, while the structure and distribution of coal production will continue to improve. Large modern coal mines are expected to account for 87% of the country's total production capacity, according to the plan. The plan also aims to significantly improve coal mine safety, green development, and the clean and efficient use of coal. Smart mines are expected to account for 75% of total production capacity, while the development of a more diversified coal-based industrial structure will be accelerated. Coal consumption is expected to peak during the plan period, alongside the establishment of a more robust mechanism for balancing supply and demand. The plan places energy security alongside the green transition as key priorities. Focusing on the development of a modern coal industry system, it outlines nine major tasks, including optimizing coal development and spatial distribution, accelerating industrial restructuring, and strengthening the production, supply, storage and sales system. Other priorities include advancing the green and low-carbon transition, improving the clean and efficient use of coal, and promoting technological innovation. The plan also calls for stronger safety management, modernized industry governance, and a higher level of modernization across the sector. (By Tang Yuxian) 
。 The prevailing theory among scientists is that around 4.5 billion years ago when the Earth was still forming and was covered in molten lava, it was struck by an object thought to be roughly the size of Mars known as Theia.,It is believed that Theia was destroyed in the process and Earth lost a significant portion of its mass. The gravitational pull of the remains of Earth then held debris from the event in its orbit which quickly, perhaps in less than 100 years, formed into the Moon.,Now, thanks to new research coming from the Swiss Federal Institute of Technology in Zurich, we have more evidence to back that up. Patrizia Will led a group of researchers in studying six lunar meteorites discovered in Antarctica in the early 2000s.,Science & TechBeat the Heat By Traveling to the Moon, Scientists Discover Pits That Stay 63 ℉ All Year27 July, 21:42 GMT,Inside she found small glass beads containing helium and neon that were formed during volcanic eruptions during the Moon’s early life. These gases are called noble gases because of their relatively low volatility. They are believed to have originated from Earth, inherited when the Moon was created in the aforementioned massive impact.,Scientists believe that because of the amount found in moon rocks and lunar meteorites, they must have come from Earth. The theory is that after the great collision, noble gases floated around Earth while superheated to thousands of degrees. The Moon formed at the same time and much of the noble gases settled in and on the Moon.,Had the gases come from elsewhere, like dust traveling on solar winds, scientists would expect there to be far less of it.,Despite their relative abundance, they're still fairly rare, and no study had been able to prove the existence of the gases in lunar meteorites before.,‘Best Physical Models Can’t Fit The Data’: Radio Bursts Detected in Space ‘Defy’ Existing Theories7 August, 14:45 GMT,Will was able to do so by weighing individual molecules to determine the makeup of chemical substances using an advanced mass spectrometer from the Noble Gas Laboratory at ETH Zurich.,Scientists are also trying to figure out how the noble gases got to Earth in the first place. There are two prevailing theories: that they were delivered here by comets and meteorites, or that they were present in a nebula cloud when the Sun was still young, and while Earth was forming, it pulled them in.,The plan is to look for other noble gases like krypton and xenon. If they are found on lunar meteorites and similar instances of the gases are found in other meteorites, then that would suggest that Earth likely got its noble gases from collisions early in its life. If not, that would lend more weight to the nebula theory.,The study’s authors say they found some evidence of krypton and xenon on the lunar meteorites, but more research will be required to confirm that.。
