Taking a tour of the core module of the CSS – China Space Station Tiangong the first module Taihe ” space station sky and core module- According to Shi Liming, director of the space station core module structure sub-system of the General Design Department of the Fifth Academy of Aerospace Science and Technology Group, the core module is very large The length is higher than a five-story building, the diameter is much wider than that of trains and subway cars, and the volume is larger than any cabin of the International Space Station. After the astronauts are stationed, the space for activities is very spacious. In addition, the weight of the core cabin is equivalent to the total weight of three buses, and it also exceeds any cabin of the International Space Station.
According to Zhang Hao, the chief designer of the space station system of the General Design Department of the Fifth Academy of Aerospace Science and Technology Group, the sealed cabin of the Tianhe core module is equipped with six areas: working area, sleeping area, sanitary area, dining area, medical supervision and medical insurance area and exercise area. .
Not only can it ensure that each astronaut has an independent sleeping environment and a dedicated bathroom, but also a microwave oven, refrigerator, water dispenser, folding table and other homes in the dining area, as well as space treadmills, space bicycles, and anti-resistance tensile devices Equipment to meet the daily exercise of Taikonauts- astronauts. The core module can also realize the communication between the astronauts in orbit and the space-to-earth communication; it is also equipped with space-to-earth video communication equipment, which can realize two-way video communication with the ground; in addition, there is a measurement and control communication network that can support astronauts to send and receive e-mails and related equipment.

After the successful completion of the core module mission, the upgraded docking mechanism undertaken by Shanghai Aerospace is about to usher in a new task] In the space station mission, Shanghai Aerospace is also responsible for the power subsystem, docking and transposition mechanism subsystem, measurement and control communication products, and resource module structure. With the general assembly and cable network development tasks, they are like loyal “guards” guarding the safe operation of the core module and the safety of the astronauts. In mid-May, the Tianzhou-2 cargo spacecraft will be launched in Wenchang and will be the first to realize docking with the Tianhe core cabin. The two experimental modules of Wentian and Mengtian are inseparable from the perfect docking of the Tianhe core module and the formation of a T-shaped space station.
For this “core battle”, as early as late January this year, the Shanghai Aerospace Technology Research Institute deployed elite core of talent personals from various units to form a “Tianhe Test Team.” During the hour waiting for the solar wing to open, Cheng Lei, the deputy chief designer of the solar battery wing from the 805 Institute, was both nervous and calm. “This is the first time that no tests have been carried out at the launch site,” Cheng Lei said. The flexible solar wing integrates four new technologies, including large-area lightweight, repeatable development and high reliability, 10 years of long life in orbit in low orbit, and high load-bearing capacity of rigid and flexible….

As of 23rd November 2020 Monday, The CNSA –China National Space AdministrationBelt and Road Initiative CLEP- China Luna Exploration Program.. Lunar Mission on the One Hundred Kilometer diameter Von Karman Crater Chang’e 4 lander and the “Yutu 2” lunar rover the Chang’e-4 lander and the “Yutu-2” lunar rover have completed 24 Day -month scientific exploration on the back of the moon … in which Chang’e-4 completed the 24th day of the work, 嫦娥五号探月 is about to embark on a journey to the moon…… The Chang’e-4 lander and the “Yutu-2” lunar rover were at 12 o’clock and 3 on November 22, respectively finished the 24th day of the month at 10:10, and entered the moonlight sleep. As of today, Chang’e-4 has worked on the back of the moon for 690 Earth days, with a cumulative mileage of 589.6 meters.
Based on the 23rd month and day panoramic camera stitched images, DOM images and other data, the “Yutu 2” lunar rover continued to move towards the basalt direction and the high reflectivity impact crater area during the 24th day. Both locations are located northwest.
The infrared imaging spectrometer carried on the “Yutu-2” lunar rover obtained the spectroscopic and mineralogical characteristics of the lunar soil and lunar rocks on the inspection route, in order to reveal the material composition of the landing zone, especially the largest impact basin on the moon-Antarctica-Ai …..The deep lunar material composition contained in the Turken Basin provides important support. The scientific results were published in the international journal “Remote Sensing”.
On the far back of the moon, Chang’e 4 completed its 24th day of the moon and entered moon night dormancy; at the Hainan Wenchang Space Launch Field in the motherland, Chang’e 5 has stood on the launch tower, and a “new partner” will soon be ushered on the moon. . At present, various systems are undergoing various tests and other final preparations, and the mission has entered the launch implementation phase, and Chang’e 5 is about to embark on a journey to the moon. Different from the first and second phases of the lunar exploration project, the Chang’e-5 mission of the third phase of the lunar exploration project has a “two-way ticket”, which will realize my country’s first automatic sampling and return of extraterrestrial objects, and complete the lunar exploration project “around, fall, and return.” “Three-step strategic planning has laid a solid foundation for follow-up tasks.
As of 10 November 2020, The CNSA –China National Space AdministrationBelt and Road Initiative Lunar Mission CLEP on the One Hundred Kilometer diameter Von Karman Crater Chang’e 4 lander and the “Yutu 2” lunar rover the Chang’e-4 lander and the “Yutu-2” lunar rover have completed 21-month scientific exploration on the back of the moon. They broke through 677 Earth Days On the far back of the moon, the Chang’e 4 lander and the “Yutu 2” lunar rover ended their moon night dormancy at 3:12 on November 10 and 10:17 on November 9 respectively. They were awakened by light and ushered in the first 24 days. Up to now, Chang’e-4 has successfully operated for 677 Earth days.
Based on the data of the panoramic camera spliced images and DOM images of the detection point, the “Yutu-2” lunar rover will continue to drive northwest during the 24th day of the month, targeting the basalt direction or the impact crater area with high reflectivity. Near the noon of the moon, the “Yutu-2” lunar rover plans to take at least one panoramic camera ring shot, and the infrared imaging spectrometer, neutral atom detector, and lunar radar will carry out simultaneous detection.
Go to the nearest impact crater with brighter reflectivity (purple circled area), the red circle is the location of the rock block
As the “Yutu-2” lunar rover continues to move northwest, scientists from the core team of Chang’e-4 use the first-hand data returned to continue to produce scientific results. The scientific team recently published an article in the SCI journal “Science China Information Sciences” and pointed out that the impact during the formation of the Antarctic-Aitken Basin is likely to penetrate the lunar crust and impact deep lunar material.
Since the remote sensing observation of the back of the moon by orbiting satellites, a large number of studies have revealed the existence of mafic anomalies at the bottom of the Antarctic-Aitken Basin, which also have different chemical properties compared to returned samples and lunar meteorites. Chang’e-4 probed the sputter layer at the bottom of the impact crater in the Antarctic-Aitken Basin and found that the characteristics of mafic minerals in this area are similar to remote sensing data.
Research data shows that the mafic minerals in the rocks and lunar soil in the Chang’e 4 landing area are dominated by clinopyroxene, which has the same composition as the rapidly cooling magma system. It is believed that the material in the landing zone of Chang’e 4 mainly comes from the recrystallization of the impact melt. The patrol and detection of “Yutu-2” in this area provided a scientific basis for in-depth understanding of the cause of the mafic anomaly at the bottom of the Antarctic-Aitken Basin….
