China's lunar rover, Yutu-2, or Jade Rabbit-2, left the first ever "footprint" from a human spacecraft on the far side of the moon late at night on Thursday, after it separated from the lander smoothly. The process was recorded by the camera on the lander and the images were sent back to the Earth via the relay satellite "Queqiao", the China National Space Administration (CNSA) announced. Launched on Dec. 8, 2018, China's Chang'e-4 lunar probe, comprising a lander and a rover, landed on the far side of the moon on Thursday morning. (Xinhua)
