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.

More than One year ago on 24th November 2020, the Chang Zheng – Long March Five Carrier Rocket Launched away in CNSA – China National Space Administration China Wenchang spaceport launch, Change Five Lunar probe into orbit, opened up towards China – People’s Republic of China’s first celestial bodies sample return trip from Mons Rumker on the Lunar Surface of the moon New research achievements – Chinese scientists reveal the composition of lunar soil minerals and space wind at the landing site of Chang’e 5
Predecessors have used orbital remote sensing data to conduct extensive research on the topography and material composition of the CE-5 landing area. Recently, a series of sample analyses have advanced the understanding of lunar chronology, late lunar volcanism, and magma evolution mechanisms. Different from large-scale remote sensing observation and fine sample analysis, in situ spectral detection can not only provide local background information of the sampling area, but also be beneficial to study the characteristics of lunar soil in undisturbed and disturbed states. The Lunar Mineral Spectrometer (LMS) carried by the CE-5 lander acquired the visible-infrared reflectance spectrum of the lunar soil, which provided important data support for the study of the material composition of the lunar soil and space weathering.
Researchers from the Key Laboratory of Solar Activity and Space Weather of the National Space Science Center of the Chinese Academy of Sciences (hereinafter referred to as the “Space Center”) used the Chang’e-5 LMS in situ detection data to analyse the material composition and maturity, spectral parameters and unmixing of the lunar soil at the landing site The study shows that the mafic minerals in the lunar soil are mainly clinopyroxene, which is consistent with the chemical analysis and orbital spectral analysis results of the CE-5 sample in the laboratory.
The optical maturity and submicroscopic iron (SMFe) of the lunar soil did not change significantly before and after the rocket purge and shovel sampling. This study provides spectral evidence that the lunar soil surface experienced rapid tillage and adequate mixing.
Figure 1: (A) The measured field of view of the LMS spectral data is shown in the red box. Panoramic cameras show images of (B) lunar soil and (C) rocks, respectively. (D) LMS reflectance spectrum curve.
The red box in Figure 1A shows the observation field of LMS spectral data, where D11 is the rock block, and D14-D16 are the lunar soil spectra after shovelling. The magnified images of lunar soil and rocks are shown in Figure 1B and C, and Figure 1D shows the reflectance spectrum curve after preprocessing such as radiometric calibration and thermal correction.
Through the spectral parameter map of the absorption features at 1 μm and 2 μm (Fig. 2A), it was found that with the increase of calcium content, the absorption positions of pyroxene at 1 μm and 2 μm moved to the long-wave direction, and the lunar soil and rocks at the CE-5 landing site For high-calcium pyroxene, this is further confirmed in the 1 μm absorption center and the ratio projection of the 2 μm to 1 μm absorption area (Fig. 2B).
In this study, the Hapke model and the sparse unmixing algorithm were used to invert the mineral composition and abundance of the in situ spectra. The inversion results were consistent with the analysis results of CE-5 samples and the inversion results of orbital remote sensing (Fig.
Figure 2: LMS in situ spectral composition analysis
Space weathering is a common phenomenon of spectral reddening and darkening caused by micrometeorite impacts and solar wind injection on non-atmospheric celestial bodies.
First, the maturity of the lunar soil at the CE-5 landing site was qualitatively analyzed by using the projection maps of the spectral slopes R950/R750 and R1600/R700 and R750 and R700 respectively (Fig. 3A, B). It was found that compared with the lunar soil at the CE-4 landing site, the The lunar soil in the CE-3 and CE-5 landing areas is relatively immature, which may be related to the fact that CE-3 and CE-5 landed on a young impact crater sputter carpet (<100 Ma).
This study further calculated the optical maturity (OMAT, Fig. 3C) and submicroscopic iron (SMFe, Fig. 3D) content, and found that there was no significant change in lunar soil maturity before and after the rocket purge, and before and after scooping, indicating CE-5 landing The lunar soil in the district has experienced an equivalent exposure history within the scooping depth (<3cm).
This result is consistent with the radionuclide analysis results of the Apollo drilling samples and the simulation results of the lunar soil tillage model. This study provides spectroscopic evidence that the lunar soil surface undergoes rapid tillage and adequate mixing.
