Three months after China’s Chang’e-6 lunar probe returned to Earth, scientists are uncovering groundbreaking secrets about the moon’s far side. The samples brought back by the mission have provided unprecedented insights into the moon’s geology, marking a significant leap in our understanding of Earth’s only natural satellite.
Last week, researchers announced key differences between the lunar samples retrieved by Chang’e-6 and those collected during the earlier Chang’e-5 mission. The Chang’e-6 samples appear slightly lighter in color due to variations in mineral composition. They contain significantly more plagioclase—a common rock-forming mineral—and less olivine, suggesting distinct geological processes on the moon’s far side.
Moreover, the Chang’e-6 samples have a lower density, indicating a more porous and loosely structured composition. This finding hints at the unique environmental conditions and impact history of the moon’s far side, which has remained largely unexplored until now.
Completing a 53-day journey in June, the Chang’e-6 mission made history as the first to return material from the moon’s far side, bringing back 1,935.3 grams of invaluable lunar samples. This achievement not only demonstrates the Chinese mainland’s growing capabilities in space exploration but also contributes significantly to global lunar research.
“The Chang’e-6 mission represents a significant milestone in the history of human lunar exploration,” said Yang Wei, a researcher at the Institute of Geology and Geophysics of the Chinese Academy of Sciences. “It will contribute to a more comprehensive understanding of lunar evolution.”
China’s lunar exploration program, named after the mythical moon goddess Chang’e, has made remarkable progress over the past two decades. Each mission builds upon the last, gradually unraveling the mysteries of the moon. The insights gained from Chang’e-6 are expected to inform future missions and potentially guide the search for lunar resources.
As scientists continue to analyze the samples, the world eagerly awaits further revelations about the moon’s far side. These discoveries not only deepen our knowledge of lunar history but also inspire future generations to look up at the night sky with wonder and curiosity.
