“…The self-organization characteristics of the lunar regolith are only inferred by the Yutu-2 LPR data using numerical simulations, which may be corroborated using a drilling core. However, all existing drilling cores on the Moon are located on the near side, and the maximum length is no more than 3 m [18,59,60]. This indicates that our model cannot be verified from the perspective of geology until deeper drilling can be carried out on the far side of the Moon (to at least 5 m).…”

Most previous studies tend to simplify the lunar regolith as a homogeneous medium. However, the lunar regolith is not completely homogeneous, because there are weak reflections from the lunar regolith layer. In this study, we examined the weak heterogeneity of the lunar regolith layer using a self-organization model by matching the reflection pattern of both the lunar regolith layer and the top of the ejecta layer. After a series of numerical experiments, synthetic results show great consistency with the observed Chang’E-4 lunar penetrating radar data and provide some constraints on the range of controlling parameters of the exponential self-organization model. The root mean square permittivity perturbation is estimated to be about 3% and the correlation distance is about 5–10 cm. Additionally, the upper layer of ejecta has about 1–2 rocks per square meter, and the rock diameter is about 20–30 cm. These parameters are helpful for further study of structural characteristics and the evolution process of the lunar regolith. The relatively small correlation distance and root mean square perturbation in the regolith indicate that the regolith is mature. The weak reflections within the regolith are more likely to be due to structural changes rather than material composition changes.

“…As shown in Figure 6e, on the mission, a complex drilling and sampling device was designed that intersected the lander and ascender. The penetrator implements lunar soil drilling with the form of penetration‐slewing‐impact drive and implements profile sampling with the form of double pipe single action—flexible inversion (Deng et al, 2021). NASA's VIPER mission, which is scheduled to land on the moon in 2023, is carrying three science payloads and a drill to find other parts of the moon that may be pure ice.…”

A planetary penetrator is a kind of machine that can use its special structure to independently penetrate an exoplanet and sample it for storage. It is a hot research topic in the world and has important development potential in the field of deep space exploration. Based on the analysis of relevant literature, this paper classifies and compares various representative planetary penetrator projectiles around the current research status. The development progress and key technologies of the planetary penetrator are analyzed, the current technical challenges are summarized, and the development trend of the planetary penetrator has prospected. The planetary probe has a broad application prospect, and its development will provide technical support for humans to establish extraterrestrial habitat, and play an important role in the field of deep space exploration. Currently, planetary penetrator research is still in its infancy, and the field is full of possibilities that need to be explored and improved.

“…1,731 g of lunar regolith was collected and are currently under laboratory investigations.The CE-5 site (Statio Tianchuan, IAU-name) is located within Eratosthenian-aged intermediate-Ti mare basalts (labeled as Em4/P58 by Qian, Xiao, Wang, et al, 2021), with an average thickness of ∼51 m, a total volume between 1,450 and 2,350 km 3 (Qian, Xiao, Head, , and a ∼7 m thick regolith superposed (Yue et al, 2019). The CE-5 sample-return strategy included a 2 m-drill (∼1 m was recovered) and a surface sampling device (Deng et al, 2021). The returned samples are thus likely to contain materials from different sources, including local basalts mixed by vertical and lateral transportation with exotic materials (Huang et al, 2017;Liu, Michael, Zuschneid, et al, 2021).…”

Chang'e-5 (CE-5) is China's first lunar sample-return mission. It landed in northern Oceanus Procellarum on December 1, 2020, at 43. 06°N, 51.92°W (Wang et al., 2021). 1,731 g of lunar regolith was collected and are currently under laboratory investigations.The CE-5 site (Statio Tianchuan, IAU-name) is located within Eratosthenian-aged intermediate-Ti mare basalts (labeled as Em4/P58 by Qian, Xiao, Wang, et al., 2021), with an average thickness of ∼51 m, a total volume between 1,450 and 2,350 km 3 (Qian, Xiao, Head, , and a ∼7 m thick regolith superposed (Yue et al., 2019). The CE-5 sample-return strategy included a 2 m-drill (∼1 m was recovered) and a surface sampling device (Deng et al., 2021). The returned samples are thus likely to contain materials from different sources, including local basalts mixed by vertical and lateral transportation with exotic materials (Huang et al., 2017;Liu, Michael, Zuschneid, et al., 2021). The local mare materials might be erupted from Rima Sharp and will help to better understand the nature of late-stage volcanism, deep mantle properties, and lunar chronologies; the distal materials would
