See you at 8 o'clock in the news, a little more insight. Meet you on time every morning at 8 o'clock in the morning and look out into the bigger world.
After 183 days, the space "business trip" trio triumphed today and landed safely at the Dongfeng landing field in Inner Mongolia. What is the situation on site? How did Shenzhou XIII return? What "black technology" is used?
On the morning of April 16, 2022, a "red and white umbrella flower" slowly landed on the Dongfeng landing field in Inner Mongolia, and the Shenzhou 13 manned spacecraft successfully landed, and the three astronauts returned home safely. After the medical supervision and medical insurance personnel checked the status of the astronauts, the 3 astronauts said: "Feel good. ”
From more than 300 kilometers above the ground through the atmosphere to land safely, this is also the eighth manned mission successfully carried out by the Shenzhou series of spacecraft. As the second manned spacecraft launched during the key technology verification phase of the Chinese space station, Shenzhou 13 is also the Longest-standing Shenzhou spacecraft. In this mission, the Shenzhou 13 manned spacecraft achieved several "firsts".
In the process of return, "black technology" equipment such as synchronous ignition, inertial navigation, and parachutes the size of 3 basketball courts also successfully completed the task, escorting the Shenzhou 13 astronauts to "go home" safely. Read the full >>>165007784814408
On October 16 last year, astronauts Zhai Zhigang, Wang Yaping, and Ye Guangfu boarded the Shenzhou 13 manned spacecraft at the Jiuquan Satellite Launch Center to enter the Tianhe core module, becoming the second batch of astronauts to stay on the Chinese space station. At this point, the flight crew of the Shenzhou 13 manned spacecraft after returning to The Earth has also set a new record for the continuous flight time of Chinese astronauts in orbit.
During the orbit period, with the support of ground scientific and technological personnel, the three astronauts successfully completed 2 outgoing activities and 2 "Tiangong Classroom" space teaching activities, and carried out a number of scientific and technological experiments and application projects, laying a solid foundation for the subsequent construction of the space station. This time, the three people returned home smoothly, which also means that the mainland will enter the construction stage of the space station project. Read the full >>>
Under the moon, the shenzhou, the starry night to the tianhe. The Shenzhou 13 astronauts' "space business trip" is over, and their six months of wonderful moments are recorded here. A quick glance at >>>
Continuing to focus on the space sector, earlier today, the continent successfully launched an atmospheric environment monitoring satellite, creating three world firsts.
At 2:16 a.m. on April 16, 2022, the Long March 4 Cyao 28 carrier rocket was ignited and launched at the Taiyuan Satellite Launch Center, successfully sending the atmospheric environment monitoring satellite into the predetermined orbit, and the launch mission was a complete success. The reporter learned from the China National Space Administration that the satellite will effectively promote the application of remote sensing technology in the fields of ecological environment, meteorology, agriculture and rural areas on the mainland, and is of great significance to improving the efficiency of the comprehensive application of satellite resources and promoting environmental protection.
According to the Eighth Academy of China Aerospace Science and Technology Corporation, the atmospheric environment monitoring satellite has created three world firsts in carbon dioxide detection methods and accuracy, in the active and passive detection of fine particulate matter and the polarization fire exchange detection system.
The atmospheric environment monitoring satellite is designed to operate in a 705-kilometer sun-synchronous orbit, with a total satellite launch weight of about 2.6 tons, and is equipped with five remote sensing instruments, including atmospheric detection lidar, high-precision polarization scanner, multi-angle polarization imager, ultraviolet hyperspectral atmospheric composition detector and wide-frame imaging spectrometer, and is a multi-element comprehensive monitoring satellite integrating carbon dioxide laser active detection, fine particulate matter stereo detection, gaseous pollutant detection and surface environment detection.
The researchers also independently carried out high-temperature accelerated life tests and other work, and the cumulative power-on time under the high temperature condition of +55 °C exceeded 4000 hours, and its equivalent on-orbit life can be as long as 10 years. Read the full >>>
Among the registered volunteers in Beijing, there is a group of compatriots from Taiwan, who have participated in more than 500 volunteer service projects. Chen Wencheng from Changhua, Taiwan, is one of them, come and see his story.
Of the nearly 4.5 million registered volunteers in Beijing, more than 200 are from Taiwan and have participated in more than 500 volunteer service projects.
On April 13, the "Together to the Future" - Beijing Winter Olympics Volunteer Service Cloud Sharing Activity jointly organized by the Beijing Municipal Committee of the Taiwan Democratic Self-Government League and the Beijing Volunteer Service Federation was held at the Taiwan Association in Beijing, and Chen Wencheng from Changhua, Taiwan, shared his experience and experience of volunteering to participate in the Winter Olympics.
Born in 1989, Chen Wencheng is a physical education teacher at Peking University. In 2011, after graduating from the Department of Physical Education of Changhua Normal University in Taiwan, Chen Wencheng studied for a master's degree and a doctorate at Beijing Sport University and Peking University. During his studies, he met his current wife, and then stayed in Beijing to work and live, forming a "cross-strait family".
In 2019, the mainland launched the "Taiwan Resident Residence Permit", Chen Wencheng applied for it for the first time; after the mainland opened up taiwan compatriots to obtain a vocational qualification certificate, Chen Wencheng was admitted to the sports agent level 3 vocational qualification certificate and the outdoor mountain instructor primary certificate.
Today, he is working in the Physical Education and Research Department of Peking University and also serves as the head of the "Haidian Taiwan Youth Station" in Beijing. He named the team "Bay Family", which is also known as "Bay Family".
Before the Winter Olympics, Chen Wencheng served as the captain of the Taiwan Youth Winter Olympics City Volunteer Service Team, he overcame various difficulties, organized 10 team members, and participated in the cross-strait creative theme activities of the Winter Olympics from January 25 to March 13 this year, such as "Fish and Dragon Dance Lantern Greeting the Winter Olympics", "Learning Lei Feng Volunteer Service to Help the Winter Paralympics", with a total of 723 hours of service hours and a total of more than 380,000 service trips.
Chen Wencheng told reporters: "The spirit of volunteerism is a small spark and a seed, and I am willing to carry forward the spirit of volunteer service in cross-strait exchanges and enhance mutual exchanges and understanding between the two sides of the strait." Read more >>>
