The reporter learned from the First Academy of Aerospace Science and Technology Group that the Long March 8 Yao-2 carrier rocket has completed all the research and development work before leaving the factory.
In the follow-up, the Long March 8 Yao-2 carrier rocket will complete the final assembly and testing at the launch site, and it is planned to complete the launch mission at an opportunity from late February to early March. This launch will be the first launch mission of my country's new generation of carrier rockets in 2022.
The Long March 8 is a new generation of medium-sized two-stage liquid-bound launch vehicles that can be launched from the Wenchang Space Launch Site and the Jiuquan Satellite Launch Center.
The total length of the rocket is 50.3 meters, the diameter of the first stage of the core is 3.35 meters, the diameter of the second stage is 3 meters, the diameter of a single booster is 2.25 meters, and the take-off mass of the rocket is about 356 tons. It is mainly used to launch payloads in low-earth orbit or sun-synchronous orbit. A 5-ton payload was sent into a 700-kilometer sun-synchronous orbit.
On December 22, 2020, the Long March 8 carrier rocket completed its maiden flight at the Wenchang Space Launch Site.
The Long March 8 carrier rocket uses green and environmentally friendly liquid propellant, and is developed according to the idea of modular combination, fully absorbing the development achievements of the in-service and new-generation carrier rockets. It has good inheritance, advancement, adaptability and economy. It can be It will fill the gap in my country's sun-synchronous orbit carrying capacity and meet the needs of future high-density launch missions in low and medium orbits.
