Description

technical field [0001] The present application relates to the technical field of space environment detection, in particular to a multi-functional space high-speed dust characteristic detector. Background technique [0002] In the future, our country will carry out a series of deep space exploration missions. These missions will involve the detection of the characteristics of interplanetary dust in the solar system. The speed of interplanetary dust is generally in the range of 1km / s to 70km / s, which belongs to high-speed dust. Most of the particle sizes are in the micron range. The comprehensive detection and research of dust characteristics, using sensors to obtain in-situ measurement data, can answer a series of major scientific questions, such as the formation and evolution of the solar system, the source of water on the earth, etc., and at the same time can obtain space dust The impact data of deep space probes can solve engineering problems in the implementation of missi...

Problems solved by technology

[0003] At present, a series of interplanetary dust detection missions have been carried out in the world, and a large amount of interplanetary dust detection data has been obtained, and the interplanetary dust detection technology has also been gradually updated and upgraded. However, my country has not yet launched a detection mission for interplanetary dust. In the lunar dust detection missions that have been implemented in my country, the Chang'e-3 and Chang'e-5 landers are equipped with quartz crystal microbalances to measure the accumulation of lunar dust, but the measurement parameters are single, and the dust cannot be fully obtained. Several important features of
