China on Sunday launched a new Earth observation satellite, Gaofen-7, which will play an important role in land surveying and mapping, urban and rural construction and statistical investigation, according to the China National Space Administration (CNSA).
The Gaofen-7, launched on a Long March-4B rocket at 11:22 a.m. (Beijing Time) from the Taiyuan Satellite Launch Center in north China's Shanxi Province, is China's first civil-use optical transmission three-dimensional surveying and mapping satellite that reaches the sub-meter level, CNSA said.
The satellite and carrier rocket were developed by the China Academy of Space Technology and the Shanghai Academy of Spaceflight Technology under the China Aerospace Science and Technology Corporation.
The users of the Gaofen-7 satellite will be mainly from the Ministry of Natural Resources, the Ministry of Housing and Urban-Rural Development and the National Bureau of Statistics.
Via the same carrier rocket, three other commercial and scientific experiment satellites including one developed for Sudan were also sent into space.
The development of the Gaofen-7 has achieved a breakthrough in sub-meter level 3D mapping camera technology, meeting the highest mapping accuracy requirement among the Gaofen series Earth observation satellites, CNSA said.
It can obtain high-resolution optical 3D observation data and high-precision laser altimetry data and can realize 1:10,000 scale satellite 3D mapping for civil use in China, according to CNSA.
An international team of researchers have discovered an amber containing an ancient bird dating back around 100 million years.
The specimen found in Hukawng Valley in northern Myanmar, an area rich in amber fossil discoveries, will help enrich understanding of the diversity of ancient birds and the evolution of feathers. The result of the research was published in Scientific Reports.
The specimen is currently stored at the Yingliang Stone Nature History Museum in Quanzhou, Fujian Province. No bones are preserved in the new specimen but the outline of the bird foot is recorded in a detailed skin surface, which is surrounded by feathers.
Unlike previous discoveries in the same area, the bird's toes are very stout, and the outer toe appears strongly thickened relative to the inner two digits. The strong toes are similar to current raptors, which may indicate that the specimen is a small aerial insectivorous bird, according to Xing Lida, a paleontologist from the China University of Geosciences.
This type of foot has not been found in local fossil records, indicating the diversity of birds in the dinosaur era.
India will make its second attempt to carry out soft landing on the Lunar surface in the near future, said Indian Space Research Organisation (ISRO) chief K. Sivan on Saturday in the capital.
India's first attempt of landing on the Moon surface was unsuccessful on Sept. 7, when the Lander "Vikram" of the second Moon Mission - 'Chandrayaan-2' lost contact when it was nearly two kilometers away from making a soft landing on the Lunar surface.
Replying to a query if ISRO would attempt another landing on Moon's south pole, Sivan replied, "Definitely", according to media reports.
Speaking at an event in New Delhi, the ISRO chief said "We want to demonstrate the technology for Vikram Lander landing, We are working on a plan of action about how to go ahead for Vikram Lander landing."
If India's Moon Mission-2 had been successful, the country would have become the fourth country to land a spacecraft intact on the Moon.
Vikram was to land on the Moon and deploy the six-wheeled rover "Pragyaan", that would have explored the lunar surface.
North China's Tianjin Municipality will have around 6,000 5G base stations built by China Mobile, a major telecommunications operator, by the end of 2020, the company's Tianjin branch said.
So far, the Tianjin branch of China Mobile has built more than 2,000 5G base stations in the city, covering many key areas such as the Sino-Singapore Tianjin Eco-City. The figure is expected to reach 3,000 by year-end.
In early June, China granted 5G licenses for commercial use, marking the beginning of a new era in the country's telecommunications industry.
According to the China Academy of Information and Communications Technology, 5G technology is expected to create more than 8 million jobs by 2030.
Multiple published reports say that the U.S. government has launched a national-security review of the China-owned video app TikTok, popular with millions of U.S. teens and young adults.
The reports Friday from Reuters,The New York Times and others said that the interagency Committee on Foreign Investment in the United States, which reviews acquisitions by foreign firms, has opened an inquiry into TikTok owner ByteDance's 2017 acquisition of a predecessor app, Musical.ly.
Several senators have recently noted concerns about censorship and data collection on TikTok.
The Treasury Department, which houses CFIUS, said it does not comment on specific cases because the agency by law cannot disclose to the public information filed to it.
TikTok said it cannot comment on ongoing regulatory processes. But it said it "has made clear that we have no higher priority than earning the trust of users and regulators in the U.S. Part of that effort includes working with Congress and we are committed to doing so."
After acquiring Musical.ly, Beijing-based ByteDance merged it into TikTok. Musical.ly, popular in the U.S. and Europe, had operated out of offices in Shanghai and California.
Sen. Marco Rubio (R-Fla.) last month sent a letter to Treasury requesting a CFIUS review of the national-security implications of the Musical.ly deal, saying there is "ample and growing evidence" that TikTok is censoring content that is not in line with the Chinese government. In the letter, he said there had been questions about why the app had so few videos of the recent protests in Hong Kong.
Sen. Tom Cotton (R-Ark.) and Sen. Chuck Schumer (D-N.Y.) later in October asked for the U.S. intelligence community to assess national-security risks of TikTok and other Chinese-owned content platforms in the U.S. They said that while TikTok says it stores U.S. user data in the U.S., the company must still adhere to Chinese law on supplying information to the government. Such accusations have also been leveled against other Chinese companies, including Huawei.
The senators also said that TikTok is a potential target of foreign influence campaigns similar to Russia's attempts to undermine the 2016 U.S. election on Facebook.
TikTok has said its data is not subject to Chinese law and that it does not remove content based on "sensitivities related to China."
On the app, people share short videos, often set to music. They lip-sync and dance to songs, do silly pranks and share other bits of their lives. It's searchable by user names, songs and hashtags, like "thisishalloween" or "tiktokcats."
The government has stepped in several times over the past few years to block or break up Chinese deals. A Chinese company that owns the gay dating app Grindr reportedly agreed to sell it earlier this year after a CFIUS review. Broadcom, based in Singapore, was stopped from going after U.S. chip maker Qualcomm because of U.S. national-security concerns over losing dominance in the race to for leadership in "5G" wireless, particularly to China. Qualcomm is a major telecom supplier.
