Guangzhou’s first commercial aerospace rocket company has started construction

Reusable rockets can significantly reduce the cost of entering space. On the one hand, it is an update of technology iterations, and on the other hand, it reflects cost reduction and efficiency improvement. China Aerospace Science and Technology Corporation is also planning the first flight of a liquid rocket. "Lijian 2" is a medium-sized liquid launch vehicle under development by China Aerospace Science and Technology Corporation. It has a take-off thrust of 751 tons, an SSO carrying capacity of 7.8 tons, and a LEO carrying capacity of 12 tons. It is planned to fly for the first time in June 2025; the first mission is to The low-cost cargo spacecraft marks its entry into constellation networking and large-payload space missions.
The Lijian-2 will be maiden on June, 2025.

The Lijian-2 liquid carrier rocket will make its first flight in 2025 and is scheduled to perform important launch missions

In January 2024, China Aerospace and the Microsatellite Innovation Institute of the Chinese Academy of Sciences (hereinafter referred to as the "Satellite Innovation Institute") held a discussion and confirmation meeting on the overall plan for the low-cost cargo transportation system of the China Space Station in Shanghai, and it was clarified that China Aerospace Lijian 2 No. 1 liquid launch vehicle launched by the Satellite Innovation Institute, a low-cost cargo spacecraft product independently developed by the Institute, will carry out its first flight mission in 2025 and undergo full-process on-orbit assessment and verification. At the same time, the first flight can also carry low-orbit Internet constellation satellites.

In order to further reduce the cost of uplink cargo transportation to the space station and enhance the flexibility of uplink cargo transportation, in May 2023, the China Manned Space Engineering Office issued a solicitation announcement for the overall plan of the low-cost cargo transportation system of the China Space Station. The China Aerospace and Satellite Innovation Institute targeted China In order to meet the low-cost cargo transportation mission requirements of the space station project, we jointly carried out ship-arrow joint demonstration and key technology research, and carried out the design of the "ship-arrow-cargo" integrated space and ground transportation system, using a low-cost cargo spacecraft and the Lijian-2 liquid launch vehicle. The ship-rocket collaboration solution was successfully shortlisted in the program bidding organized by the China Manned Space Engineering Office, received support from the China Manned Space Engineering Office, and entered the detailed design stage of the program.

"Lijian 2" is a medium-sized liquid launch vehicle independently developed by China Aerospace Science and Technology Corporation. It inherits the excellent genes and advanced technology of "Lijian 1". The Lijian 2 liquid launch vehicle adopts CBC configuration and has a universal core diameter. 3.35 meters, with a total length of 53 meters, a take-off mass of 628 tons, and a take-off thrust of 766 tons. SSO has a carrying capacity of 7.8 tons, and LEO has a carrying capacity of 12 tons. It has the ability to launch into sun-synchronous orbit, low-Earth orbit, and transfer orbit. It will become my country's low-cost cargo spacecraft and satellite Internet group with large transportation capacity, high reliability, low cost, and excellent service. It is the main rocket for launching Internet and space science satellites, as well as deep space exploration missions.

As the aerospace vehicle industrialization platform of the Institute of Mechanics of the Chinese Academy of Sciences, CAS and the Satellite Innovation Institute jointly implemented the Chinese Academy of Sciences' first joint independent satellite and rocket launch. After returning from the successful first flight, China Aerospace Science and Technology Corporation closely followed the launch missions of various satellite payloads of the Satellite Innovation Institute, completed the demonstration of launch plans for multiple satellites and payloads, and established a deep strategic partnership. As soon as the China Manned Space Engineering Office announced the mission, the Satellite Innovation Institute immediately started joint demonstration work with China Aerospace Science and Technology Corporation.

Facing the three core requirements of "high carrying capacity, high efficiency and low cost" for the low-cost cargo transportation system of China's space station, the development team designed the "ship-arrow-cargo" integrated space and ground transportation system, focusing on the low-orbit batch production design concept, Key technologies such as multiple means of weight reduction and quality assurance, high-intelligence-assisted packing, and fully digital design have proposed solutions for flexible configuration, high load-to-cargo ratio, efficient process, and freight guarantee, forming an ultra-cheap, ultra-fast, ultra-packaging, ultra- Five iconic achievements including safety and ultra-comfort.

The low-cost cargo spacecraft launch mission planned to be carried out by the Lijian-2 liquid launch vehicle is the first time that a Chinese commercial aerospace enterprise has participated in the development and launch of a low-cost cargo transportation project for the China Space Station. It will enhance the innovative vitality and market competitiveness of my country's aerospace field. Significant. China Aerospace is a "new force" in China's commercial aerospace industry. As a platform for transforming the results of major national scientific research projects, it always adheres to the original intention of serving the country through aerospace, is guided by the major strategic needs of my country's aerospace field, and gives full play to the advantages of the new national system and mixed ownership. , continue to enhance independent innovation capabilities, accelerate research on key core technologies, further promote the innovative development of China's aerospace science, space technology, and space applications, and make new and greater contributions to improving human welfare!
The payload might be Cargo Spaceship (货运飞船) and Digui Hulianwang Constellation Satellites (低轨互联网星座卫星).
