Specifically, it includes the completion of the first flight of the Long March-6C and Long March-12 launch vehicles; The space station entered the normal operation mode, and completed 2 cargo spacecraft, 2 manned spacecraft launch missions and 2 return missions during the year. Promote the fourth phase of the lunar exploration project, launch the Queqiao-2 relay satellite and the Chang'e-6 probe, and achieve the world's first sample return to the south pole on the far side of the moon; A number of civil satellites such as the Ocean Salinity Detection Satellite, the Electromagnetic Monitoring Satellite 02, the Sino-French Astronomical Satellite, and the Shijian-19 Satellite were launched to meet the application needs of users in various industries; Accelerate the construction of the "new generation of commercial remote sensing satellite system" of the Aerospace Science and Technology Group.
Promote the development of Chang'e-7 and Tianwen-2.
In 2024, the research and development tasks of the Aerospace Science and Technology Group will continue to maintain high intensity, and will comprehensively promote the manned lunar exploration project and deep space exploration project, continue to promote the development of more than 200 spacecraft represented by the new generation of near-earth manned spacecraft, Chang'e-7, Tianwen-2, and geostationary orbit microwave exploration satellites, carry out more than 230 launch vehicle groups and put into production in batches, and complete the performance of a number of commercial aerospace and whole satellite export contracts.
A number of commercial launch missions will be completed.
According to reports, the Aerospace Science and Technology Group will also complete a number of commercial launch missions, and will publicly release the carrying margin information, provide commercial users with launch and carrying opportunities, and provide fast, stable and reliable "one-stop" launch services for all kinds of customers. Facing the needs of major national strategies and economic and social development, we will realize the extension of Beidou application to system integration and value-added services, give full play to the advantages of space-ground integration and the comprehensive application advantages of satellite communication, navigation and remote sensing of the group company, continuously integrate satellite applications into emerging fields, and support the economic development of key regions.
In addition, according to the Blue Book, China's aerospace will carry out 67 launch missions in 2023, ranking second in the world, developing and launching 221 spacecraft, and the number of launches and spacecraft has set a new record in China, of which 47 launches of the Long March series of carrier rockets have been successful, with a cumulative launch of more than 500 launches, and 20 launches of other commercial rockets.

A new member of the Long March family of launch vehicles has been added.
A new member has been added to China's Long March series of launch vehicles, laying the foundation for future reusable rockets. The reporter learned from the press conference held by the China Aerospace Science and Technology Corporation in Beijing yesterday that the Long March 12 carrier rocket has completed various research and development work, and is carrying out the first general test of the first arrow, and plans to complete the launch of the first rocket at China's first commercial launch site in Wenchang, Hainan Province in 2024.
Zeng Wenhua, the overall chief designer of the Long March 12 launch vehicle, said that the Long March 12 carrier rocket was developed by the Eighth Academy of Aerospace Science and Technology Group (CASC) and was China's first 3The 8-meter-diameter single-core liquid launch vehicle has a two-stage configuration, with four liquid oxygen and kerosene engines with a thrust of 1,250 kN in the first stage and two liquid oxygen and kerosene engines with a thrust of 180 kN in the second stage. The carrying capacity of low-earth orbit shall not be less than 10 tons, and the carrying capacity of 700 kilometers of sun-synchronous orbit shall not be less than 6 tons. The fairing comes standard with 52 meters and 42 m diameter, multi-size adaptation according to different tasks.
The biggest feature of the Long March 12 launch vehicle is that it is the first of its kind in the Long March series familyThe diameter of the rocket body of 8 meters, which is based on the improvement and development of the YF-100 series of China's new generation of main liquid oxygen kerosene engines, and the maximum envelope boundary constraints of China's railway transportation capacity, after repeated demonstration and research, and a large number of transportation tests have been done with the railway department, which can not only be transported by railway to China's launch sites, but also realize the best adaptation of the diameter of the rocket body and the number of engines, realize the expansion of capabilities and the universality of one arrow, and lay the foundation for the future reuse of rockets. Zeng Wenhua said.
Experts from the Eighth Academy of Aerospace Science and Technology Group said that the Long March 12 carrier rocket inherits the efficient single-core stage tandem configuration of the current Long March series rockets, which is simple, reliable and has good mission versatility, improves the sun-synchronous orbit orbit orbit and low-orbit multi-constellation networking capabilities, further improves and broadens the type spectrum of China's new generation of launch vehicles, helps the high-quality development of China's space transportation system, and improves the single-core liquid rocket carrying capacity and large fairing envelope to a new level.

Tang Hongbo became China's longest-flying astronaut in orbit.
As of February 26, Shenzhou-17 astronaut Tang Hongbo, who is on a business trip to China's space station, has a total flight time of 215 days in orbit, becoming China's longest astronaut in orbit.
Tang Hongbo is the second batch of astronauts in China and the first astronaut to return to China's space station.
On June 17, 2021, he and his comrades-in-arms Nie Haisheng and Liu Boming successfully drove the Shenzhou 12 manned spacecraft into space, realizing their dream of flying for the first time and experiencing the historical moment of "Chinese entering their own space station for the first time". They successfully returned to Earth on September 17 and stayed in orbit for three months for a total of 92 days.
On October 26, 2023, Tang Hongbo returned to Tiangong as the commander of the Shenzhou-17 crew, becoming the Chinese astronaut with the shortest interval between two missions so far, and felt the Chinese speed and power demonstrated by the Chinese space station from "one bedroom" to "three bedrooms".
Up to now, he and his comrades-in-arms Tang Shengjie and Jiang Xinlin have been flying in orbit for 123 days, completed the crew's first out-of-cabin activity, ushered in the Tianzhou-7 cargo spacecraft, carried out a large number of scientific experiments and technical tests, and also spent the Spring Festival of the Year of the Dragon in space, held the third "Tiangong Painting Exhibition", etc., their "space business trip" time has passed half, and Tang Hongbo's number of days in orbit is still growing.
In the 21 years since Yang Liwei asked the sky in 2003, China's manned space program has made world-renowned achievements, and the number of Chinese who have left a presence in the vast space has reached 20, especially with the normalization of manned missions in the space station stage, China's astronauts who have exceeded 200 days in orbit have also reached 3, namely Jing Haipeng who patrols the sky four times, Chen Dong and Tang Hongbo who have flown twice.
What is even more exciting is that the lunar landing phase of China's manned lunar exploration project has been fully launched, and Chinese astronauts will set more records in the vast universe.
