Source Title: Successful Launch of the Chang’e-5 Probe Kicks Off China’s First Return Trip for Extraterrestrial Object Sampling
The reporter learned from the National Space Administration that at 4:30 on November 24, China successfully launched the probe of the Chang’e 5 Lunar Exploration Project with the Long March 5 Yaowu carrier rocket at the Space Launch Site. Wenchang in China, and successfully sent the probe into scheduled space. Orbit, starting the first trip back to our country from samples of extraterrestrial objects.
After the Long March 5 Yaowu carrier rocket was launched into space, it carried out four separations, including booster separation, fairing separation, primary and secondary separation, and rocket separation.
The Chang’e-5 probe consists of four parts: an orbiter, a return, a lander, and an ascendant. After subsequent earth-moon transfer, near-moon braking and circumlunar flight, the lander and ascendant combination will combine with the orbiter and the returner assembly separates, the orbiter carries the returner to remain in orbit, and the lander carries the ascender to make a soft landing in the preselected area of the lunar front and to perform follow-up work such as auto-sampling the lunar surface as planned.
The Chang’e-5 mission plan to achieve three main engineering goals: first, break key technologies such as narrow-window multiple-orbital link launch, lunar surface automatic sampling and packaging, lunar surface liftoff, lunar orbital encounter and docking and storage of lunar samples to enhance China’s aerospace technology; The second is to carry out China’s first automatic sampling and return of extraterrestrial celestial bodies, and promote major advances in science and technology in China; The third is to improve the lunar exploration engineering system to accumulate important talents, technology and material bases for China’s future manned lunar landing and deep space exploration.
The scientific objectives of the Chang’e-5 mission are mainly to carry out landform area detection and geological background study, obtain the on-site analysis data related to lunar samples, establish the connection between the site exploration data and laboratory analysis data; carry out the lunar sampling system, long-term laboratory research to analyze the structure, physical properties and material composition of the lunar soil, and deepen the investigation on the origin and evolution of the moon.
The Chang’e-5 mission is organized and implemented by the National Space Administration, and is specifically comprised of five main systems including the overall project and detectors, launch vehicles, launch sites, measurement and control and recovery, and land applications. The National Space Administration’s Center for Aerospace Engineering and Lunar Exploration is the general engineering unit. The China Academy of Launch Vehicle Technology, affiliated with the China Aerospace Science and Technology Corporation, is responsible for the development of carrier rocket systems, and the China Academy of Space Technology is responsible for the development of detection systems. The Ministry of Satellite Launch, Measurement and Control System of China is responsible for organizing the launch, measurement and control and recovery. The National Astronomical Observatory of the Chinese Academy of Sciences is responsible for the research and development of terrestrial application systems and is responsible for the reception, processing and storage management of scientific data and samples.
The China Lunar Exploration Project is an important national science and technology special reference project clearly defined in the National Medium and Long-Term Science and Technology Development Plan (2006-2020). It is the focus of the Party Central Committee on the overall situation of China’s socialist modernization and aims to promote the development of the aerospace industry and promote science and technology. An important strategic decision was made to advance and innovate and enhance the overall national strength. Since the project was established and officially launched in January 2004, it has successively implemented Chang’e 1, Chang’e 2, Chang’e 3, re-entry flight test and Chang’e 4, etc. Five missions.
This launch mission is the 353rd launch in the Long March series of carrier rockets.
