On 31st August 2022羲和the Team of Xihe Sun exploration results officially released…..The official release of “Xihe” sun exploration results set a number of international “firsts”…… A reporter from the Global Times learned from the National Space Administration on the 30th that on the same day, China’s first solar exploration science and technology test The results of the satellite “Xihe” were officially released. The “Xihe” Sun Exploration Achievement Conference is mainly focused on solar scientific exploration and new satellite technology, setting five international firsts.

The full name of “Xihe” is the solar Hα spectral detection and double-super-platform science and technology experiment satellite. It was launched on October 14, 2021 and operates in a sun-synchronous orbit with an average altitude of 517 kilometers. The main scientific payload is the solar Hα imaging spectrometer. . As my country’s first dedicated solar “photographer”, after preliminary on-orbit testing and debugging, “Xihe” has successfully achieved the world’s first space solar Hα band spectral scanning imaging, and the world’s first in-orbit acquisition of solar Hα and SiΙ spectral lines and the fine structure of FeI lines. According to the fine structure of these spectral lines, high-precision all-solar chromospheric and photospheric Doppler velocity fields can be inferred, and the activities occurring in the solar atmosphere can be recorded in detail, so as to study the physical process of solar activity. At present, the “Xihe” is carrying out scientific observations every day according to the established mission plan. Nearly 100 solar eruptions have been observed, and related research work is being carried out. The scientific data of “Xihe” is open to the world for sharing.


In addition to the achievements in solar scientific exploration, in terms of new satellite technology experiments, “Xihe” International has achieved the first time the master-slave collaborative non-contact “double super” (ultra-high pointing accuracy, ultra-high stability) satellite platform technology on-orbit performance Verification and engineering application; realized the in-orbit application of the world’s first solar space Hα imaging spectrometer; realized the in-orbit verification of the world’s first atomic frequency discrimination solar velocimeter. A slight vibration of the satellite load in space will make the imaging effect poor by the slightest and a thousand miles away. The “Double Super” satellite platform breaks the technical bottleneck of “unpredictable and difficult to control” micro-vibration of the traditional satellite platform, and adopts the maglev control technology to completely isolate the physical contact between the platform and the payload, ensuring that the payload imaging is not affected by the platform disturbance, allowing its Taking pictures is “more stable and more accurate”, and the attitude control level of my country’s satellite platform has been improved by 1 to 2 orders of magnitude, reaching the international advanced level. In the future, the dual-superplatform technology will be popularized and applied in a new generation of space missions such as high-resolution remote sensing, three-dimensional solar detection, and exoplanet discovery, promoting the leap-forward development of my country’s space technology.


“Imitate Xi and Yu Tianma, and aim to herd the stars in the sky.” Over the past year, the National Space Administration has organized the Aerospace Science and Technology Group, Nanjing University, Chinese Academy of Sciences and other mission-contracting units to successfully complete the on-orbit test and experiment of the “Xihe” spacecraft, and achieved major achievements in the “Xihe” sun exploration. It is a model project of cooperation between government, industry, academia, research and application. At present, the National Space Administration has organized relevant units to put forward a series of mission plans such as solar detection at the L5 point of the sun, solar polar orbit detection, and solar approach detection. Evolution contributes to the development of human scientific civilization….

Fig. 2 Analysis of physical and mechanical properties of lunar soil based on “Yutu” 2 wheel-earth interaction

The team estimated the mechanical properties of the lunar soil based on the information on the interaction between the lunar rover wheel and the lunar surface and the ground mechanical model. The results show that the pressure-bearing properties of the lunar soil regolith are similar to the dry sand and sandy loam on the earth, and are similar to those in the American Apollo program. Compared with typical lunar soil, it has stronger pressure bearing characteristics. Large lumps of soil were observed adhering to the wheels of “Yutu 2” in images from different locations, while the wheels of “Yutu 2” basically had no clay phenomenon, indicating that the lunar soil cohesion near the landing area of ​​Chang’e 4 is relatively large , the reason may be that it contains a higher proportion of aggregates, which makes soil particles more likely to agglomerate after being rolled by wheels.

#MadeInChina #中國製造|#WFST #WideFeildSurveyTelescope April2022 | #UniversityofScienceandTechnologyofChina incredible #China- #PeoplesRepublicOfChina has built a new advance Next generation of #SkySurvey #Telescopes with a primary mirror diameter of 2.5 meters and 720 million pixels Scientific Imaging Detector Test Platform Completed”

On 14th April 2022 China – People’s Republic of China has incredibility  has built a new generation of sky survey telescopes with a primary mirror diameter of 2.5 meters and 720 million pixels with Another Chinese Tianyan opened? Qinghai Lenghu will build a survey telescope with a primary mirror diameter of 2.5 meters….  Which If you use a lens with a diameter of 2.5 meters and a photosensitive element with 720 million pixels to make a telescope, how far can it see? How clear will things be?

​​

China – People’s Republic of China is currently manufacturing such a telescope. It is co-operated by the University of Science and Technology of China and the Haixi Mongolian and Tibetan Autonomous Prefecture of Qinghai Province. One of the sites of the astronomical observatory), the Wide Field Survey Telescope, whose full name is the University of Science and Technology of China – Purple Mountain Observatory of the Chinese Academy of Sciences Large Field Survey Telescope, English name Wide Field Survey Telescope, referred to as WFST, it is China – People’s Republic of China The new generation of astronomical survey telescopes developed by the State, a major national astronomical observation infrastructure, will become the optical time-domain survey telescope with the strongest ability to survey the sky in the northern hemisphere after completion.

​According to the news from the University of Science and Technology of China on April 11, the research and development team composed of the university and the Purple Mountain Observatory of the Chinese Academy of Sciences has completed the development of the primary mirror CCD290 camera and CCD test system. The relevant results have been published in the world famous astronomical instrument. In the publication “Journal of Astronomical Telescope Instruments and Systems”, this innovative research result laid the foundation for the development of the main focus camera for the large field telescope.

The large-field survey telescope is a new generation of astronomical telescopes developed in my country. The diameter of its main mirror is 2.5 meters. The design adopts the international leading main focus optical mode, which can provide a large field of view, high precision and wide-band sky survey capabilities. , its photosensitive element is a large area array 720 million pixel splicing CCD detector, which is spliced ​​by 9 CCD290-99 chips, the imaging array reaches 9K x 9K, and the imaging area reaches 92.2 mm × 92.4 mm, with ultra-low noise readout capability , the readout noise can be less than 5 electrons at a readout rate of 500Kpix/s.

​The main focus camera with

​Some people call the large-field survey telescope “another Chinese sky eye”. It is true that both have strong sky survey and observation capabilities, but the two are very different. In terms of observation methods, the Chinese sky eye (FAST) It does not move, basically just patrols the night sky with the rotation of the earth. It is impossible to fix the viewing angle at a certain point in the night for detailed observation, but WFST can dynamically patrol the night sky and can fix a certain celestial object on the sky. long time observation.

​As the strongest large-field optical survey telescope in the northern hemisphere, WFST is a “three-in-one” powerful prime focus camera that integrates “scientific imaging, wavefront detection, and guide star sensing”. It can discover countless galaxies, quasars and stars in the huge cosmic space, and can also monitor large-scale celestial collisions, supernova explosions, stellar helium flashes, fast radio bursts and other transient sources in distant cosmic spaces, as well as the Milky Way and nearby galaxies. Appearing variable stars and other celestial bodies, small celestial bodies such as asteroids and comets in the Kuiper belt in the solar system and far away can also be seen. In addition, the structure and formation and evolution history of galaxies can be judged by observing the star stream in the Milky Way and nearby galaxies.
