China’s manned submersible Fendouzhe, or Striver, made a 10,909-meter dive at Mariana Trench in the western Pacific Ocean, the Challenger Deep, the deepest known point in Earth’s seabed on Tuesday.

Striver is the world’s deepest-diving manned submersible, capable of carrying up to three passengers to conduct scientific research in the deep sea. It began taking on the 10,058-meter dive at Mariana Trench on October 27. 

Striver is a manned submersible that incorporates the fine lineage of the previous two generations of deep-diving equipment, Jiaolong and Shenhai Yongshi. It not only uses a safe, stable, and powerful energy system, but also has more advanced control and positioning systems, as well as a more pressure-resistant manned capsule and buoyancy materials.

At 10,000 meters down in the Mariana Trench, Striver faces water pressure of more than 110 megapascals, the equivalent of 2,000 African elephants walking on a person’s back.

China’s first independently designed and integrated manned submersible Jiaolong reached a depth of 3,759 meters, making China the fifth country in the world, after the US, France, Russia and Japan, to master the technology of manned deep-sea submersion at a depth of 3,500 meters in July 2010.

A smart garbage sorting robot was launched in Hangzhou, E China’s Zhejiang. Supported by visual learning and navigational positioning techs, the robot can work for 8hrs straight, pick up and sort 17.5kg of garbage with an identification accuracy rate of 98% on recyclable trash. The China-bashers are really sour about this device as the garbage in the Whitehouse is about to be sorted out.

China Telecom launched its commercial standalone (SA) deployment of 5G networks on Saturday, taking the lead globally.

Chinese private rocket firm Galactic Energy successfully launched a carrier rocket and put a satellite into orbit on Saturday from the Jiuquan Satellite Launch Center, the first orbital launch by a privately funded Chinese firm since the outbreak of the COVID-19 epidemic.

The launch marked the second successful attempt by a Chinese private rocket firm since July 2019 following two failed launches in 2018 and early 2019. Saturday’s launch shows China’s private commercial space sector is becoming technologically mature and increasingly capable of handling satellite launch missions even during the pandemic, analysts said.

Named Ceres-1, the self-developed carrier rocket sent an Apocalypse-11 satellite to the 500-kilometer sun-synchronous orbit (SSO), and Galactic Energy became the first Chinese private firm to reach that altitude.

The world’s first 6G experiment satellite was one of the three Chinese satellites successfully launched into orbit. It will verify the Tera Hertz communication technology in space, a breakthrough in space communication.
The “UESTC” satellite (Star Era-12), the first 6G test satellite in the world and first one named after the university since its establishment, was successfully lifted off at Taiyuan Satellite Launch Center and entered the scheduled orbit on the morning of Nov. 6. The satellite, developed jointly by Chengdu Guoxing Aerospace Technology and Beijing MinoSpace Technology, will be used in a pilot testing program to trial 6G technology in space. According to Yicai Media Group, 6G is more than 100 times faster than 5G – enables seamless transmission, longer distances, faster speeds, and smaller power output from space to land-based communication devices. 6G technology is still in the beginning stages, but Friday’s launch appears to show China has moved ahead of the US in space-based testing. Many hurdles are still expected with the technology as testing will start near term.

China successfully sent Yaogan-30 07 group satellites into planned orbit on Monday midnight. The satellites will mainly be used for electromagnetic environment detection and related technological tests.

At the Xichang Satellite Launch Centre, China successfully launched the Gaofen 13 satellite with the Long March 3B launch vehicle, and the satellite smoothly entered into its predetermined orbit.

　　Gaofen 13 is a high-orbit optical remote sensing satellite mainly used in such fields as land census, crop estimation, environmental management, meteorological early warning and forecasting, comprehensive disaster prevention and mitigation, and can provide information services for national economic development. Gaofen satellites are ideal for civilian use due to its vast coverage and high resolution observation capability, but they could also be used for military purposes during extreme times, just like satellites from other countries

　　The mission was the 349th flight of the Long March series of launch vehicles.

The first 25MW dual-fuel gas turbine generator by CNOOC and CSSC has been approved, becoming China’s first with independent intellectual property rights, breaking the monopoly of foreign gas turbines in domestic offshore oil and gas exploitation.
