Yutu moon landing data

Wu Zhijian, spokesman of the Bureau of Science and Technology for National Defense, announced that the Chang 'e-3 lunar probe is scheduled to be launched in early February, and it shoulders the heavy responsibility of "landing on the moon", which is the first soft landing of the China spacecraft on an extraterrestrial object. At present, Chang 'e "Three Women" and its improved Long March 3B rocket are preparing to launch in xichang satellite launch center. Wu Zhijian made the above remarks at the first press conference of Chang 'e-3 mission held by the National Defense Science and Technology Bureau yesterday.

The first lunar rover was named "Jade Rabbit"

Li Benzheng, deputy commander-in-chief of China's lunar exploration project, announced yesterday that China's first lunar rover, Chang 'e III, was named "Jade Rabbit".

Chang 'e III is one of the most complicated and difficult tasks in China's space field so far. Since the State Council approved the project in 2008, the research team has gone through three stages: scheme design, initial sample development and prototype development. "The Chang 'e-3 probe, which consists of a lander and a patrol, will realize the soft landing of China spacecraft for the first time, and the proportion of new research technologies will reach more than 80%. "Wu Zhijian said," In the process of project implementation, there are seven hurdles, including timely launch with multiple windows and narrow width, soft landing of the moon, separation of the two devices, remote operation of the moon and the earth, survival of the moon, TT&C communication and ground test verification. "

It is reported that the lander landed the patrol boats Hug and Jade Rabbit on the moon, and then Jade Rabbit left the lander to conduct scientific exploration on the surface of the moon for about three months. The lander conducts in-situ detection at the landing site.

Shoulder three major scientific exploration tasks

Wu Zhijian said that Chang 'e III shoulders three major engineering objectives and three types of scientific exploration tasks.

Three major engineering goals: to break through the key technologies such as lunar soft landing, lunar patrol survey, TT&C communication and teleoperation in deep space, launch of launch vehicle for deep space exploration, and improve the level of space technology; Develop lunar soft landing detector and patrol detector, establish ground deep space station, and obtain functional modules including launch vehicle, lunar probe, launch site, deep space monitoring and control station and ground application. , with the basic ability to detect the soft landing of the moon; Establish the moon

Explore the basic system of aerospace engineering and form a scientific and effective engineering method for implementing major projects.

Three kinds of scientific exploration tasks: investigation of lunar surface morphology and geological structure; Investigation of material composition and available resources on the surface of the moon; Earth plasma layer detection and moon-based optical astronomical observation.

"As the main task of the second phase of the lunar exploration project, the Chang 'e III mission is a key step in the three steps of' circling, falling and returning', which is of great significance to the development of the entire lunar exploration project and even the aerospace industry." Wu Zhijian said.
