Shulou(Shulou.com)11/24 Report--

CTOnews.com, May 21, according to the China manned Space Engineering Office, the secondary wreckage of the long March 7 Yao-7 carrier rocket re-entered the atmosphere at around 14:05 on May 21, 2023, located in the South Pacific Ocean (151.6 °W, 31.2 °S), and most of the devices were ablated and destroyed during re-entry.

CTOnews.com previously reported that on May 10, the long March 7 Yao Seven launch vehicle ("long Seven Rocket") lifted the Tianzhou 6 cargo spacecraft successfully, which was the first launch of China's manned space engineering mission in 2023 and the first launch mission in the application and development phase of China's space station. On the occasion of the seventh anniversary of the first flight of the Chang 7 rocket, it successfully handed in a high-quality answer paper with seven times.

The Chang-7 rocket is developed by the China Academy of launch vehicle Technology (hereinafter referred to as "Rocket Academy") under the China Aerospace Science and Technology Corporation. In 2022, the Rocket Academy successfully completed the construction of the Chinese space station by seizing the six victories of the long March 5B, long March 7 and long March 2F three rockets developed by the General Administration. In 2023, China's manned space program will enter the stage of operation and development of the space station, and the long March 7 and long March 2F carrier rockets will carry out three launch missions.

As China's first-generation medium-sized carrier rocket with high reliability and high safety, the Chang-7 rocket has the highest orbit accuracy among the active carrier rockets, with a deviation of no more than 4 seconds. In the mission of launching the Tianzhou V cargo spacecraft, the spacecraft set a world record of two hours for autonomous rapid rendezvous and docking. As the basic type of China's new generation of medium-sized carrier rockets, the scientific research team has derived long March 7A, long March 8 and other carrier rockets on the basis of Chang 7 rockets.

At present, the Chang-7 rocket is mainly responsible for the launch of Tianzhou cargo spacecraft, which is a "special freight train" to build a "heaven-earth transport corridor" to provide material support for the normal operation of China's space station at a frequency of one or two launches a year. In the follow-up, while satisfying the freight mission of the space station, the Chang-7 rocket will also carry the upper stage of the expedition to achieve the carrying capacity of 9.5 tons in the sun-synchronous orbit and actively expand the launch market of medium-and low-orbit satellites.
