It has travelled nearly 1.5 kilometers and released more than 940.1GB scientific data of scientific data at all levels.

 Blessings for the Year of the Rabbit! This year is the traditional Chinese Year of the Rabbit. In the hearts of Chinese people, the most famous rabbit must be the “Jade Rabbit” from ancient Chinese myths. . China Aerospace has such a “Jade Rabbit”, which also lives on the moon. It is the “Yutu-2” lunar rover in my country’s lunar exploration project. On the occasion of the Chinese New Year in the Year of the Rabbit, it sent back the latest photographs from the moon 380,000 kilometers away, sending a New Year blessing.

In which Chang’e-4 research results reveal the secrets of the Antarctic-Aiken Basin The cause of the abnormal area of ​​composition…..

The South Pole-Aiken Basin is the largest impact basin on the Moon, with a diameter of over 2,400 kilometers. The study of the South Pole-Aiken Basin is of great significance for revealing the origin of the lunar asymmetry, the impact process, the early evolution process and the composition of the deep material. Orbital remote sensing observations show that there is a compositional anomaly in the center of the Antarctic-Aiken Basin. The planetary science team of Shandong University analyzed and interpreted the in-situ visible and near-infrared spectral data of the Yutu-2 lunar rover and found that the lunar crust is the Antarctic-Aiken composition anomaly. The main material source provides important constraints for the future exploration of materials in the Antarctic-Aiken Basin and even the deep parts of the moon.


​The main material components on the lunar The material composition at the bottom of the South Pole-Aiken Basin is abnormal, and the content of mafic silicate minerals and iron is significantly higher than that in the peripheral area of ​​the basin (Figure 1).

Figure 1. The distribution of iron and pyroxene content inside and outside the Antarctic-Aiken Basin

Most of the previous studies on the material composition of the Antarctic-Aiken Basin only focused on mafic minerals. Due to the anomalous characteristics of mafic in this region, there has even been a debate about whether the lunar mantle is peridotite or pyroxene. Although according to the lunar magma ocean hypothesis, olivine and pyroxene are the main minerals of the lunar mantle, the plutonic magma intrusion after the formation of the lunar crust can also form rocks rich in olivine or pyroxene in the lunar crust, so olivine is enriched Or pyroxene does not serve as evidence of origin from the lunar mantle. So far, humans have not obtained samples from the Antarctic-Aiken Basin and returned to Earth, and their trace elements and isotopic characteristics cannot be known. Among the material composition information available through remote sensing or in situ detection, the plagioclase content also distinguishes crust-derived and mantle-derived rocks. key indicators.

Numerical simulation studies believe that during the excavation process of the South Pole-Aiken impact, the lunar crust has been completely stripped, but in the subsequent transformation stage, the collapse of the instantaneous crater wall may cause the lunar crustal material to slip off the bottom of the basin. In addition, other basin impact events after the Antarctic-Aiken impact event also produced a backfilling effect on the bottom of the Antarctic-Aiken Basin, and the exposed lunar mantle material or impact melting products during the formation of the basin is likely to have been diluted by the lunar crust material. Mineralogical and geochemical unmixing analysis results show that the lunar soil on the surface of the anomalous area is composed of about 70% of the lunar crust material and about 30% of the material enriched in iron and incompatible elements.

On 27th June 2022 the Chinese Academy of Sciences Research Reveals the Constraints of the Chang’e-4 Infrared Imaging Spectroscopic Ground Validation Experiment on the Material Composition of the Lunar SPA Surface

The Infrared Imaging Spectrometer (VNIS) on the Yutu No. 2 Lunar Rover has measured infrared imaging spectral data at multiple locations along the rover’s walking route. VNIS is the main method used to study the composition of lunar soil and lunar surface rocks in the landing area and to trace their origin. The research of the Institute of Geology and Earth Sciences, Chinese Academy of Sciences revealed the constraints on the composition of the lunar SPA surface by the Chang’e-4 infrared imaging spectroscopy ground verification experiment.

The Yutu-2 rover has been working on the lunar surface for more than 40 months, and the infrared imaging spectrometer (VNIS) it carried has measured infrared imaging spectral data at multiple locations along the rover’s walking route. VNIS is the main method used to study the composition of lunar soil and lunar surface rocks in the landing area and to trace their origin. However, factors such as space weathering, particle size and multiple scattering, the spectral response of the instrument, and observation conditions all affect the spectral characteristics and lead to large uncertainties in the mineral composition calculated from the lunar surface spectral data.

  In order to quantitatively evaluate the reliability of different VNIS data processing methods, Chang Rui, a doctoral student in the Key Laboratory of Earth and Planetary Physics, Institute of Geology and Geophysics, Chinese Academy of Sciences, under the guidance of his supervisor researcher Yang Wei and associate researcher Lin Honglei, selected a mineral composition with Spectroscopic ground verification experiments were performed on the Suchang-gabbro with similar lunar highland rocks (Fig. 1). The rock (CR-1) studied by the ground verification experiment has an actual mineral pattern content of 12.9% olivine, 35.0% pyroxene and 52.2% plagioclase, as measured by scanning electron microscopy. In order to more accurately calculate the spectral results of CR-1, the researchers ground and sorted the olivine, low-calcium pyroxene, high-calcium pyroxene and plagioclase from the rock samples in CR-1. -4, ASD) to measure the visible-near-infrared spectral results of each single mineral (Fig. 2a), and each single mineral has its own spectral absorption characteristics. The spectrum of CR-1 measured by the VNIS identifier showed distinct absorption features at the 971 (±1) nm and 1957 (±8) nm bands (Fig. 2b). This absorption feature is similar to the rock absorption feature detected by VNIS on the Yutu-2 rover on the third day of the month. The Hapke model of the VNIS spectrum of CR-1 calculated the mineral pattern content of the sample to be 7.5% olivine, 39.3% pyroxene and 53.2% plagioclase, which were consistent with the true results within the error range.

  According to the data processing method in this study combined with the photometric correction of the Chang’e-4 lunar surface data by Yang et al. (2020), the more accurate mineral model content of the rocks detected by the Yutu-2 rover on the third day should be 11.7 % olivine, 42.8% pyroxene and 45.5% plagioclase. The rover found another lunar surface rock on the 26th day with spectral absorption characteristics similar to those found on the 3rd day, with mineral pattern contents of 3.2% olivine, 24.6% pyroxene, and 72.2% plagioclase. The two lunar surface rocks belong to the sutraite category in the “Anorthosite-Norite-Troctolite” (ANT) system (Fig. 3) (Heiken G, 1991), which means that the Chang’e-4 landing area lunar The rock formations under the soil are mainly ANT rocks. The rocks detected by the Yutu-2 rover on the 26th day contained more plagioclase and were closer to the mineral composition of the average lunar crust.

  To sum up, the lunar surface of the Chang’e-4 landing area has su-long and plagio-like rocks, which represent the material formed by the rapid crystallization in the impact melting pool and the composition of the average lunar crust, respectively. On the one hand, an impact event excavated material from the underlying layers of lunar soil to the lunar surface. These excavated materials have the characteristics of crystalline plutonic rocks in the molten pool of the South Pole Aitken Basin (SPA). On the other hand, the initial lunar crustal material formed before the SPA big impact event can also be retained in the SPA.

  The related research results were published in Remote Sensing . The research work has been funded by the Strategic Pilot Science and Technology Project of the Chinese Academy of Sciences, the Key Deployment Project of the Chinese Academy of Sciences, the Innovation Interdisciplinary Team of the Chinese Academy of Sciences, the Civil Aerospace Pre-research Project of the National Space Administration, and the Key Deployment Project of the Institute of Geology and Geophysics of the Chinese Academy of Sciences.
