Chinese spacecraft landed on far side of moon | China Change's 4 mission 


Change's 4 landed in the unexplored South Pole-Aitken basin, which is the largest, oldest and deepest crater on the moon's surface.


China on Thursday successfully landed a spacecraft on the far side of the moon, becoming the first in history to touch the lunar surface unseen from Earth, according to media reports.

The China National Space Administration (CNSA) landed the robotic probe — Change's 4 — in the unexplored South Pole-Aitken basin, which is the largest, oldest and deepest crater on the moon's surface. The probe entered an elliptical path around the moon last weekend, drawing up to 15-kilometre close from the surface.

The Change's-4 was launched from Xichang, southwestern China, on December 8. The probe reached the final orbit around the moon after 22 days and transmitted the first-ever "close range" image of the dark side of the moon.

The mission is one in a series that underscore the country's ambitious plan to join the space race. Followed by the United States and Russia, China is only the third country to send its own astronauts into space on its own rockets.

The moon is tidally locked to Earth, rotating at the same rate that it orbits our planet, so the far side - or the "dark side" - is never visible from Earth. Previous spacecraft have seen the far side of the moon but none has landed on it.

The landing "lifted the mysterious veil" from the far side of the moon, and "opened a new chapter in human lunar exploration", reported Global Times. The mission aims to take detailed measurements of the moon's terrain and mineral composition.

The landing was also greeted by Nasa administrator Jim Brindestine. He tweeted:
China now plans to begin fully operating its third space station by 2022. It not only plans to send probes to Mars but also retrieve samples of the Martian surface.
