News on September 17 According to a CCTV news report, at about 13:30 on September 17, the Shenzhou 12 manned spacecraft’s return cabin reverse thrust engine successfully ignited and landed safely in the scheduled area of the Dongfeng landing site. This is the first time the Shenzhou spacecraft has landed at the Dongfeng landing site.

The door of the Shenzhou 12 return cabin was opened, and the three astronauts were in good condition.

According to CCTV news, in the Shenzhou 1 to Shenzhou 11 missions, the Dongfeng Landing Site was used as a backup landing site for manned missions. It has been constructed simultaneously with the Siziwangqi Landing Site. With the continuous development of my country’s manned space project, Dongfeng Landing The advantages of field normalization and emergency standby continue to appear.

On June 17, 2021, the Shenzhou 12 manned spacecraft was launched from the Jiuquan Satellite Launch Center. Three astronauts Nie Haisheng, Liu Boming, and Tang Hongbo led the expedition and started a three-month flight mission. The three became the first space visitors after China's manned spaceflight entered the space station stage.

The Shenzhou 12 manned flight mission is the seventh manned space flight organized and implemented by my country, and it is also the first manned space flight during the key technology verification and construction phase of the Chinese space station. During the operation in orbit, the astronauts completed the long-term stay test in the space station assembly, which tested the space station assembly's ability to guarantee the life, work, and health of the astronauts, related technologies, and the ability of the astronauts to perform flight missions. At the same time, the astronauts organized and implemented two out-of-vehicle activities, and with the support of the robotic arm, they carried out operations such as the assembly of related equipment outside the space station.

The crew of the Shenzhou 12 astronauts worked and lived in the space station complex for 90 days, setting a record for the duration of a single mission by Chinese astronauts. Before returning, the Shenzhou 12 manned spacecraft and the space station combination completed the circumnavigation and radial rendezvous tests, which successfully verified the radial rendezvous technology and laid an important technical foundation for subsequent manned missions.

According to CCTV, my country’s second-generation new crown vaccine has completed phase II clinical trials.

Recently, news about the development of the second-generation new crown vaccine and specific drugs for the treatment of new crown pneumonia has received widespread attention. What role will the second-generation vaccines and specific drugs play in preventing the new crown pneumonia epidemic? When will it be listed?

Head of the Vaccine R&D Team of the Scientific Research Group and Director of the Science and Technology Development Center of the National Health Commission, said: “First, my country’s vaccine R&D units have carried out research on inactivated vaccines against Gamma and Delta strains. Research on broad-spectrum or multivalent recombinant protein vaccines of different mutant strains, the third is to develop adenovirus vector vaccines and nucleic acid vaccines against Beta strains and Delta strains."

Zhu Jingjin, Secretary of the Party Committee of Sinopharm Group China: "At present, we have prepared vaccines against variant strains such as Delta and Beta. Broad-spectrum recombinant protein second-generation vaccines have also been developed, and phase I and II clinical trials have been completed.

DoNews, September 9 news (Ding Fan) Recently, Huawei officially announced via Weibo that it will hold a new Huawei Smart Office product launch conference at 19:30 on September 13 with the theme "Free Creation, Unbounded Communication".

According to the poster, Huawei stated that “the mobile phone can play, TA is also OK”, and also displayed the mobile app icons such as Douyin and Dianping in the warm-up poster, which seems to imply that this new product will be able to directly run the Android App. , Can take into account part of the mobile phone experience, which will bring great help to the office scene and improve efficiency.

It is reported that Huawei will release two notebooks, Matebook 13S and 14S, on September 13, using Intel processors. From the naming point of view, they will be equipped with 13-inch and 14-inch large screens. There is also news that the "14-inch large-screen mobile phone" that was exposed a few days ago refers to this 14-inch screen Matebook 14S notebook. Unlike Win11, it is reported that Huawei has adopted self-developed citation technology to realize the development of mobile apps. run.

In addition to notebooks, Huawei will release a large wave of brand-new products for office scenes this time, which may include new monitors, all-in-one products, and laser printers essential for office work, which will greatly improve work efficiency. promote.

News from September 7 Yesterday, Huawei officially stated that HarmonyOS was new to the Sample this week and 5 new examples were added, including the JsFACard example function, the JsRouter example, the NativeImage example, the JsTimer example, and the JsDevice example.

Huawei Hongmeng HarmonyOS 2 adds 5 new Sample examples

Sample1: Update the JsFACard sample function

Scenario: This example shows the service card function, through which important information of the user application is displayed on the desktop. This time, the function of using cards through shortcut gestures has been added to achieve the purpose of direct service and reducing hierarchical jumps.

News on August 23 Tianwen 1 was launched from the Wenchang Space Launch Site in Hainan by the Long March 5 Yaosi carrier rocket at 12:41 on July 23, 2020, and entered Mars orbit on February 10, 2021.

According to Xinhua News Agency, today is 13 months for Tianwen-1 to travel in space and dream of Mars. It is also a day for the Zhurong rover to spend 100 days on Mars safely, and it is also a crucial day for the mileage to exceed 1,000 meters. Today, Zhu Rong, which has successfully completed its mission, has set a new record on the surface of Mars and created infinite possibilities.

my country’s first Mars exploration mission successfully landed on Mars on May 15, 2021. As of August 15, the "Zhu Rong" rover has been operating on the surface of Mars for 90 Martian days (about 92 Earth days), traveling a total of 889 meters. All scientific payloads were turned on for detection, and a total of about 10GB of raw data was obtained. The "Zhurong" rover successfully completed the scheduled inspection mission.

Officials said that the "Zhurong" rover is currently in good condition, stable on foot, and sufficient energy. In the future, it will continue to drive to the ancient land-sea junction in the southern Utopia Plain to implement expansion missions.

1000 meters in 100 days, Zhu Rong set a new record

"Zhurong" Mars rover navigation terrain camera, surface composition detector, subsurface detection radar, meteorological measuring instrument, orbiter high-resolution camera, subsurface detection radar (very low frequency mode), ion and neutral particle analyzer, etc. 7 The data obtained by Taiwan's scientific load has completed the relevant processing and quality verification work, and has formed a standard data product. The China Lunar and Deep Space Exploration Network has opened data applications to domestic scientific research teams, and subsequent scientific data will be released in batches on a monthly basis. .
