China’s lunar probe returned to Earth with the first samples of the unexplored far side of the Moon. Chang’e-6 landed in the desert Mongolia Interior Tuesday, after a nearly two-month mission fraught with risks.
Scientists are eagerly awaiting Chang’e-6, as samples could answer key questions about how planets form. China is the only country to have landed on the far side of the Moon, having done so before in 2019.
The far side, which is far from Earth, is technically difficult to reach due to its distance and difficult terrain of giant craters and few flat surfaces. Scientists are interested in this less explored sideas it is believed that it may contain traces of ice, which can be harvested for water, oxygen and hydrogen.
Chang’e-6 took off from a space center in early May and successfully landed in a crater near the south pole of the Moon A few weeks later. His mission lasted 53 days. The probe will be sent to Beijing and samples will be collected there, according to the state broadcaster CCTV.
This is China’s sixth mission to the Moon and the second to the far side. The probe is named after the lunar goddess Chang’e in Chinese mythology.
The probe used a drill and a robotic arm to scoop up dirt and rocks, took some photos of the surface, and planted a Chinese flag. The United States, China and the former Soviet Union collected samples from the near side of the Moon, but China is the first to bring back material from the far side. The goal was to collect up to 2kg of moon rock and soil.
China previously collaborated with international scientists toto study samples he brought back from the visible side of the Moonbut it is unclear whether similar access will be granted to new material from the dark side.
The latest samples could help answer some questions about the early history of the solar system. For example, the Aitken Basin – one of the largest impact structures in the solar system – formed 4.26 billion years ago, a few hundred million years after most lunar craters, which They were destroyed by asteroids and comets during a violent period known as the Late Heavy Bombing.
“Was the basin formed as part of the last heavy bombardment? Or was it a separate event? By obtaining precise dates for the basin and the craters that cover it, we will be able to better understand the history of the moon,” the Planetary Society explains on its website in a description of the Chang’e 6 mission.
“This also has implications for understanding the origins of life on Earth,” the Planetary Society added. “Asteroids may have transported water and organic materials to Earth during the last intense bombardment. Understanding the timing and circumstances of this event is essential to unraveling the story of our origin.”
Catherine Heymans, an astronomer at the Royal Households of the United Kingdom, told the BBC: “It is incredibly exciting to see this successful landing. Geological activity on the Moon is very different on the visible side and on the hidden side and the question of why we see those differences was a great enigma.”
Heymans hopes the recovered samples will help researchers understand the composition of the Moon’s center. “Is it very similar to Earth? Can that confirm our theory that the Earth and the Moon were once the same thing? asks the astronomer.
The Chang’e-6 mission is a source of pride for a nation that stepped up its missions to the moon, attracting the attention of its rival, the United States. State media showed officials triumphantly placing the Chinese flag just after the Chang’e-6 capsule landed in the Inner Mongolia desert.
Chinese President Xi Jinping called to congratulate those in the Chang’e-6 mission command center. Xi told them that I hoped they could continue exploring deep space to “reach new heights in unraveling the mysteries of the universe… to benefit humanity and advance the nation.”
Beijing has invested huge resources in its space program over the past decade, in an effort to catch up with both the United States and Russia. Their goal is to send a manned mission to the Moon by 2030 and plans to eventually build a base at the lunar south pole.
The United States also plans to send astronauts to the Moon again by 2026 with its Artemis 3 mission. Analysts believe that the next space race will not just be about getting people to the Moon, but about who can claim and control lunar resources.
