BACKGROUND

[0002] Near-Earth asteroids refer to asteroids closest to the Earth with a distance of less than 45 million kilometers, which may collide with the Earth in the future. At present, there are about 23,000 near-Earth asteroids that have completed orbit cataloging in the world. The impact of a near-Earth asteroid on the Earth will cause great harm. The harm forms of the impact of a near-Earth asteroid on the Earth include burning in the atmosphere, air explosion, impact on land or ocean, etc. A larger asteroid can not only cause an earthquake, tsunami, and volcanic eruption, but also can lead to global climate and environmental disasters, and even cause global biological extinction and civilization disappearance. The existing methods for disposing a near-Earth asteroid threat include impact and laser ablation, which all need to know the internal structure and other characteristics of the asteroid in advance, so as to better estimate the disposal effect. In addition, in planetary scientific exploration activities, extraterrestrial celestial body soil detection is also an important detection content. The results obtained by the internal soil detection of an extraterrestrial celestial body will provide important data support for planetary science and other aspects.

[0048] like Figures 1-5 As shown, the outer shell 1 is bullet-shaped, and the head of the outer shell 1 is oval-shaped, which is conducive to the extraterrestrial soil detection detector penetrating into the interior of the extraterrestrial body.

[0049] The soil collection structure 7 is disposed on the outer shell 1;

[0050] like Figures 5-7 As shown, the soil collection structure 7 includes a collection hole 8 and a boss 9. The boss 9 is disposed on the outer shell 1, and its top protrudes above the outer surface of the outer shell 1. In a preferred embodiment, the opening end 11 of the collection hole 8 is disposed at the junction of the boss 9 near the head of the outer shell 1 and the outer shell 1. One side of the opening end 11 of the collection hole 8 is disposed on the top of the boss 9, and the other side is disposed on the outer surface of the outer shell 1. The collection hole 8 connects the inside and outside of the outer shell 1, and collects soil in the collection hole 8 during the impact process. The angle between the axis of the collection hole 8 and the axis of the outer shell 1 is an acute angle, which facilitates soil collection. The design of the collection hole 8 and the boss 9 allows soil to be passively squeezed into the collection hole 8 during the impact process. Specifically, the design of the top of the boss 9 protruding above the outer surface of the outer shell 1 serves to block the soil during the impact penetration process, allowing the soil to be squeezed into the collection hole by the surrounding pressure.

[0051] The soil testing structure is installed inside the collection hole 8.

[0052] The number of soil collection structures 7 is multiple, and the multiple soil collection structures 7 are arranged circumferentially along the outer shell 1.

[0053] The soil testing structure includes a thermal property detector 4 and an electrical property detector 5; the thermal property detector 4 and the electrical property detector 5 are respectively disposed in different collection holes 8. In a preferred embodiment, the thermal property detector 4 and the electrical property detector 5 are installed in the collection holes 8 by threaded connection.

[0054] The volatile matter detector 2 is housed within the outer casing 1. In a preferred embodiment, the volatile matter detector 2 is connected to the outer casing 1 via threads. The heating element 6 is attached to the outer wall of the collection hole 8, which heats the soil inside the collection hole 8, allowing volatile matter in the soil to pass through the conduit 10 to the volatile matter detector. In a preferred embodiment, the heating element 6 is installed on the outer wall of the collection hole 8, where no thermal property detector 4 or electrical property detector 5 is installed. The collection hole 8 is connected to the volatile matter detector 2 via the conduit 10.

[0055] The transmitting antenna 3 is connected to the outer casing 1 by a thread; the transmitting antenna 3 is electrically connected to the volatile matter detector 2, the thermal property detector 4, and the electrical property detector 5, and can transmit the collected detection data to an external receiving device through the antenna.

Two collection holes 8 are respectively equipped with a thermal property detector 4 and an electrical property detector 5, and the other two collection holes 8 are connected to a volatile matter detector 2 via a conduit 10. Specifically, the four soil collection structures 7 have collection holes 8 namely a first collection hole 81, a second collection hole 82, a third collection hole 83, and a fourth collection hole 84, which are evenly arranged along the circumference of the outer shell 1.

[0058] like Figures 5-7 As shown, the thermal property detector 4 and the electrical property detector 5 are respectively installed in the first collection hole 81 and the second collection hole 82.

The first external thread structure 41 is connected to the first collection hole 81 by a thread. The three first probes 42 at the front end of the thermal property detector 4 are covered by the collected soil during the impact penetration process for thermal property detection.

[0060] like Figure 11 , Figure 12 As shown, the overall shape of the electrical property detector 5 is cylindrical, and its rear end is a second external thread structure 51. The second external thread structure 51 is connected to the second collection hole 82 by a thread. The two second probes 52 at the front end of the electrical property detector 5 are covered by the soil collected during the impact penetration process for electrical property detection.

[0061] like Figure 13 , Figure 14 As shown, there are two heating elements 6 and two conduits 10. The two heating elements 6 are respectively attached to the outer walls of the third collection hole 83 and the fourth collection hole 84 to heat the soil inside. The third collection hole 83 and the fourth collection hole 84 are respectively connected to the volatile matter detector 2 through different conduits 10, so that the heated volatile soil can enter the volatile matter detector 2 through the conduits 10. The overall structure of the third collection hole 83 is exactly the same as that of the fourth collection hole 84.

[0064] The present application realizes soil collection by arranging four soil collection structures 7 symmetrically around the detector shell 1. The present application adopts the method of impact extrusion to collect the soil of extraterrestrial objects, and analyzes the soil physical properties through the physical property probe in contact with the soil. In addition, the soil in the collection hole 8 is heated by the heating sheet 6 to volatilize the trace components, and then the soil volatile component detector 2 is used to detect the soil volatile components to realize the monitoring and analysis of the soil.

[0065] The present application penetrates into the target object surface to a certain depth by impact, detects the soil condition of the target object, and transmits the detected data to the relay satellite through the transmitting antenna 3, and finally transmits back to the earth, providing technical support for asteroid defense and extraterrestrial planet exploration.
