A Chinese spacecraft has lifted off from the far side of the moon but not before marking the historic visit with a bit of patriotic graffiti.

Chang’e-6, the first sample-retrieval mission to the far side of the moon, blasted off on its journey back to Earth on Tuesday after leaving a mark on the lunar surface that resembled the Chinese character Zhong, state media reported.

The character is the first part of Zhongguo, the Chinese-language name for China. It can also mean center in Chinese.
