Problems solved by technology

Japan's Hayabusa was launched in 2003 and took samples on the asteroid 25143. It was the first country to successfully collect samples on the asteroid and return it successfully. However, many failures occurred during the mission, and the ground Lost contact, needs further improvement in reliability

Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings and specific implementation, but not as a limitation to the present invention.

[0027] Depend on Figure 1-2 It can be seen that a deep-space asteroid sample collection probe mainly includes: a probe housing 1, a sampling device 2, a protection device 3, a recovery device 4, a heat insulating material 8, and a control unit 46, etc.

[0028] Such as Figure 1-3As shown, the detector housing 1 constitutes the main frame of the entire acquisition detector, and two solar panels are fixed on the two wings of the detector housing 1; the protection device 3 is fixed on the bottom of the detector housing 1, and the extension direction of the protection device is vertical On the bottom surface of the detector housing; the sampling device 2 is fixed between the bottom of the detector housing 1 and the protection device 3, and the center line of the ejection ball launching port 10...

Abstract

The invention discloses a deep-space asteroid sample collection detector which comprises a detector housing, a sampling device, a protection device, a recovery device, a heat insulation material, and a control unit; when the asteroid detector lands, mechanical grippers on the protection device are unfolded; a motor-driven lead screw allows a flexible extending material to extend to a limit length so as to be used as a conveying pipeline for dust particle samples and be used for protection of the detector; then the sampling device launches ejection balls which bump the asteroid surface through the pipeline of the protection device; the sputtered dust particles are introduced into the recovery device of the detector through the conveying pipeline of the protection device, and are packaged isolatedly. The invention is an integrated device with the functions of asteroid sample collection, recovery, and packaging, and protection of the detector itself during the sampling process is also considered.

Description

technical field [0001] The invention relates to the technical field of aerospace exploration, in particular to a deep-space asteroid sample collection probe. Background technique [0002] Asteroids are rocky or metal celestial bodies orbiting the sun. Their size is quite small, and most of them are distributed between the orbits of Mars and Jupiter. Asteroid deep space exploration is a new development direction of space exploration activities, and it is an important research field for scientists to understand the origin, evolution and life raw materials of the solar system. [0003] The environment of the asteroid is very different from that of the earth, and the gravity of the environment is almost zero, so the excavation machinery and sampling machinery used on the earth cannot be fully applied to the asteroid. At the same time, with the current technology that humans have, it is impossible to bring a large number of samples to the earth for analysis. What can be done is ...
