The lunar probe launched on Dec. 8 was decelerated to orbit the moon and choose an appropriate time for landing at the distant side of the moon. The scientific tasks, apport from surveying terrain and landforms, will be on low-frequency radio astronomical observation. Low-frequency radio observation on the front side of the moon is not very effective due to the cause of the earth’s electromagnetic environment. On the reverse side, the electromagnetic environment is very excellent, and it provides an ideal place for low frequency radio astronomy observation and research which is the most advanced in the field of space science.
