Research Advance in Lunar Space Enviornment

After more than fifty years lunar exploration, our understanding of the lunar space environment is still short. The information of lunar dusty exosphere was given by ARTEMIS mission and the lunar atmosphere and dust environment detector which were developed by NASA. Based on the radio experiments of several lunar missions, the existence of lunar ionosphere is proofed. The current status and observation of lunar exosphere and ionosphere are introduced in this paper. With the help of the low frequency radio astronomical payloads carried by chang'e-4 relay satellite and the lander, more information of lunar space environment will be detected.
