China launches Chang'e-4 lunar probe in the Xichang Satellite Launch Center in southwest China's Sichuan Province, Dec. 8, 2018. The probe is expected to make the first-ever soft landing on the far side of the moon. A Long March-3B rocket, carrying the probe including a lander and a rover, blasted off from Xichang at 2:23 a.m., opening a new chapter in lunar exploration. The scientific tasks of the Chang'e-4 mission include low-frequency radio astronomical observation, surveying the terrain and landforms, detecting the mineral composition and shallow lunar surface structure, and measuring the neutron radiation and neutral atoms to study the environment on the far side of the moon, the China National Space Administration announced. China has promoted international cooperation in its lunar exploration program, with four scientific payloads in the Chang'e-4 mission developed by scientists from the Netherlands, Germany, Sweden and Saudi Arabia.
