(Photo: China National Space Administration)Change 5, the next mission in Chinas lunar exploration program, will demonstrate and test the countrys technological and engineering capabilities in space, according to a key figure in the project.Yu Dengyun, deputy chief designer of Chinas lunar exploration program, said on Sunday that Change 5 will be launched by a Long March 5 heavy-lift carrier rocket at the Wenchang Space Launch Center in Hainan province by the end of 2020.The 8.2-metric-ton robotic probe has four components－an orbiter, lander, ascender and re-entry module. After the probe reaches lunar orbit, the components will separate into two parts, with the orbiter and re-entry module remaining in orbit while the lander and ascender descend to the lunar surface.The lander and ascender will make a soft landing and then get to work on tasks such as using a drill to collect underground rocks and a mechanical arm to gather lunar soil.After the surface operations are completed, the ascenders rocket will lift it to lunar orbit to dock with the re-entry module. It will transfer lunar samples to the module, which will carry them back to Earth.Considering these highly sophisticated operations, Change 5 will be more difficult and challenging than previous Chinese lunar expeditions, Yu said."First of all, its most important task will be collecting lunar samples. The environment on the lunar surface, like the gravity there, is very different from that on Earth. So we must ensure that our technologies are functional and reliable during the collection and packing processes," the designer explained."The next challenge will be lifting the sample-carrying ascender from the moon. All of our launches so far were made from Earth, but the coming launch will take place on lunar soil and use the Change 5s lander as the...

(Photo: Xinhua)Researchers from the Chinese Academy of Agricultural Sciences (CAAS) recently developed the world’s first breeding material that has made pigs resistant to three major infectious diseases through gene editing, while allowing pigs to maintain normal functions, People’s Daily reported on Monday.The gene editing technology, co-developed by the Institute of Animal Sciences of CAAS and universities from China and Canada, can prevent pigs from being infected by porcine reproductive and respiratory syndrome, the porcine transmissible gastroenteritis virus and the porcine delta coronavirus, according to media reports.Research results will be published online in the international journal of biology eLife.Chief expert of the research team Li Qui explained that various infectious diseases pose great threats to the pig industry, causing hundreds of billions of dollars in economic losses in 2019 alone.The porcine reproductive and respiratory syndrome, also known as “blue ear disease,” targeted by the gene editing project, is one of the deadliest threats. It is highly contagious and can cause premature delivery, late abortion, stillbirth, weak fetuses in pregnant sows and other reproductive disorders, as well as respiratory diseases in piglets.The other two diseases curbed by the technology belong to the coronavirus family, and can lead to fatal diarrhea in piglets.Up until now, there has no effective way to prevent or control these diseases. Precise genome editing, however, could achieve that goal by deleting receptor genes that mediate virus invasion, therefore blocking the viruses’ entrance into the pig’s body.After years of observation, breeding, performance testing and slaughter experiments, it appears that normal reproduction and production performances of pigs are...

File photo: CGTNChina’s Tianwen-1 Mars probe successfully completed its second mid-course correction as of 11 pm BJT on Sunday.Four 120N engines were simultaneously started and ran for 20 seconds, bringing it some 19 million kilometers away from Earth, the China National Space Administration (CNSA) said in a statement.So far, Tianwen-1 has been in orbit for 60 days and a flight distance of about 160 million kilometers. The probe is in good working condition, and the ground measurement and control communication centers and stations are tracking normally.Tianwen-1, China’s first Mars probe, made its first orbital correction on August 2, when the probe had traveled for approximately 230 hours, and was some 3 million kilometers away from Earth.Mid-course correction generally refers to the correction of the track deviation caused by various reasons during the flight of the probe. The accuracy of Tianwen-1’s launch into orbit and the first mid-course correction was very high, and only a few corrections were made this time, experts said.Tianwen-1 will have several mid-course corrections during the flight towards Mars, and will carry out scientific research on it when it lands.
China’s Tianwen-1 Mars probe successfully completed its orbital correction for a second time as of 11:00 pm Sunday Beijing time, after 60 days into its journey to the Red Planet, Global Times learned from the China National Space Administration (CNSA) on Monday morning.So far, the spacecraft has travelled some 160 million kilometers, bringing it some 19 million kilometers away from Earth, CNSA said in a statement.Four 120N engines were simultaneously started and ran for 20 seconds to pull off the second orbital correction, which in return verifies the capability of the engines, CNSA said.The probe is in good working condition, and ground monitoring and communication stations are getting good tracks of the spacecraft.Tianwen-1, China’s first Mars probe, made its first orbital correction on August 2, when the probe had traveled for approximately 230 hours, and was some 3 million kilometers away from Earth.The mid-course correction is undertaken to ensure that the spacecraft sticks precisely to the designated and theoretical flight orbit and to correct track deviation caused by various factors.According to CNSA, the extent of the second correction is very small, as the launch and first correction work was extremely surgical.Zhang Rongqiao, chief architect of China’s Tianwen-1 Mars exploration program, told the media on Friday at the 2020 China Space Conference that the entire journey of the Tianwen-1 Mars probe will last approximately 202 days, and the probe will fly 474.4 million kilometers before reaching Mars.China successfully launched the probe via a Long March-5 carrier rocket from Wenchang Space Launch Center in South China’s Hainan Province on July 23.

(File photo: Xinhua)Executives from Huawei including founder Ren Zhengfei visited the Chinese Academy of Sciences (CAS) recently to discuss fundamental research and core technology development with CAS experts and scholars, according to the Bureau of Science & Technology for Development under the CAS.The visit demonstrates Huaweis latest efforts to strengthen independent technology development in partnership with top Chinese research bodies such as CAS, following lessons learned from US technological blocks, experts said.During the visit, Ren stated that Huawei attaches great importance to its cooperation with CAS. He hopes CAS and Huawei can strengthen scientific exchanges with open attitudes, while exploring the frontiers of science and technology.CAS dean Bai Chunli also noted that the CAS has carried out "multiple-layer", "broad" and "pragmatic" cooperation with Huawei, with such teamwork having produced good results."Huawei is Chinas brand and pride. I hope Huawei and the CAS can cooperate closely, combining the innovation abilities of CAS and the resources of Huawei to explore frontier technologies," Bai said.Huawei has been increasing efforts to research independent technologies after finding itself in an awkward situation following the US order limiting the global supply of electronic components to the Shenzhen-based tech giant. Currently, the US government forces global chipmakers using US technology to obtain a license from the US before working on designs for Huawei.The US sanctions have given rise to market speculations over whether Huaweis business would be severely affected, with the possibility of severe impacts to launches of smartphones installed with high-end chips. Conversely, the sanctions are also forcing China to push technological breakthroughs following the realization that...

(Photo: chinadaily.com.cn)China is determined to land its astronauts on the moon and set up a scientific station there, according to a project leader.Zhou Yanfei, deputy chief designer of Chinas manned space program, said on Friday that China wishes to use the manned lunar missions to carry out scientific surveys and technology demonstrations, explore ways to develop lunar resources and strengthen the nations space capabilities."A new wave of lunar explorations has been emerging in the world, with participants aiming to make sustainable missions to deepen knowledge of the moon and exploit resources there," he said in a report delivered at the 2020 China Space Conference in Fuzhou, Fujian province. "Unlike other nations, China must depend on its own science and technology to realize our goals."The country is independently able to land its astronauts on the moon because it has the technologies, a group of well-trained, innovative professionals and high-efficiency research and management systems, Zhou said.Planners, designers and engineers have done feasibility research and discussed all aspects of the manned lunar program.Chinese researchers will have to overcome a long list of technical and engineering difficulties, Zhou said."Our existing carrier rockets cant perform landing missions to the moon because they are not powerful enough. The Shenzhou-series manned spaceships are not suitable for lunar expeditions. We dont have a lunar landing capsule," he said."Our ground support system was designed for operations in low-Earth orbit rather than on the lunar surface. Moreover, Chinese astronauts have no experience working on an extraterrestrial body."The first step is to produce a powerful launch vehicle.Zhou said researchers initiated two approaches－making a new heavy-lift rocket capable of deploying more than 35 metri...
