Chinese Lander Returns First Ever Samples From Far Side Of The Moon

China’s lunar probe has successfully returned the first ever samples taken from the far side of the Moon to Earth.

On June 1, Chang’e 6 touched down softly near the Lunar South Pole. This was the second time China achieved this feat, and they remain the only nation to have done so.

Though heavily cratered, the far side of the Moon does not have the deep basins and “lunar seas” seen on the near side, and its crust was measured to be thicker by the Gravity Recovery and Interior Laboratory mission in 2012. It also, weirdly, appears to be more conductive.

There are a number of theories as to why the sides should be so different, including that there were originally two Moons orbiting Earth which collided early in the Earth’s history, and that a dwarf planet collided with a smaller Earth moon later on.

Zongyu Yue, a geologist at the Chinese Academy of Sciences, told Chinese media outlet the South China Morning Post that the samples are hoped to answer “one of the most fundamental questions in lunar research – what geologic activity is responsible for the differences between the two sides [of the Moon].”

Though the far side of the Moon has been studied from orbit, there is nothing like getting your hands on samples. Hopefully, they will answer questions about how the Moon formed, while scientists also hope that the samples could contain water, oxygen, and hydrogen, which could be harvested during further exploration.
