China’s lunar mission, ‘Chang’e-6’, has achieved a historic milestone by touching down on the Moon’s far side and capturing unparalleled images of this relatively unexplored region—the first instance of materials from the Moon’s far side being returned to Earth for detailed analysis.
The mission’s crowning accomplishment featured a “selfie” taken on the lunar hidden half, thanks to the deployment of an innovative 5 kg mini-rover powered by artificial intelligence (AI). Photographs showcase the landing module, the Chinese national flag, and the tracks of the four-wheeled AI rover, documenting this groundbreaking moment.
Designed as an autonomous intelligent robot, the rover employed AI-based software to navigate the lunar surface and to determine the most advantageous angle for its self-portrait. The prime objectives for the mini-rover were capturing the “selfie” and testing autonomous intelligent technologies.
Launched from the Wenchang Spacecraft Launch Site on Hainan Island on May 3, 2024, the mission quickly entered lunar orbit within four days. ‘Chang’e-6’ came equipped with a suite of scientific instruments and made a successful landing in the South Pole-Aitken basin, a massive crater on the far side of the Moon. The mission is composed of an orbiter, a returner, a lander, and an ascender module. Following its separation on May 30, the lander began the process of collecting lunar soil and rock samples, some of which from up to 2 meters beneath the surface.
Through the aid of a relay satellite, ‘Chang’e-6’ touched down in the carefully chosen Apollo basin within the larger South Pole basin. Scientist Huang Hao explained that the site was selected due to its scientific value, communicative and remote control capabilities, and its comparatively flat terrain despite the rougher, more rugged nature of the Moon’s far side. The Apollo basin’s unique flatness was especially conducive for landing.
The ‘Chang’e-6’ mission is part of China’s Lunar Exploration Program, which has the objective of exploring the Moon’s surface and gaining a better understanding of its history and geology. Prior to ‘Chang’e-6’, the ‘Chang’e-4’ mission was the first to land on the far side of the Moon in January 2019, achieving a significant milestone in lunar exploration.
Key Questions and Answers:
– Why is the ‘Chang’e-6’ mission important? The ‘Chang’e-6’ mission is important because it helps scientists study the Moon’s far side, an area that remains less understood due to its position facing away from Earth. This can provide new insights into the Moon’s formation and evolution. Moreover, the lunar samples that ‘Chang’e-6’ aims to return to Earth will allow for more detailed laboratory analysis.
– What makes the South Pole-Aitken basin a site of particular scientific interest? The South Pole-Aitken basin is thought to be one of the oldest and largest impact craters on the Moon. Studying this basin could offer clues to the early solar system and the Moon’s crust composition, as well as the possibility of water ice, which could be crucial for future lunar exploration and permanent human presence.
Key Challenges and Controversies:
– Technical Challenges: Landing on the Moon’s far side requires overcoming significant challenges, including communication difficulties, as the Moon blocks direct radio communication with Earth. China deployed a relay satellite, ‘Queqiao,’ to facilitate communication for the ‘Chang’e-6’ mission.
– International Concerns: Space exploration, while primarily scientific, carries geopolitical implications. As more nations and private entities endeavor to explore and potentially exploit lunar resources, there is a growing need for international agreements and norms to govern activities on the Moon.
Advantages and Disadvantages:
– Advantages: Successfully deploying and operating a mission like ‘Chang’e-6’ enhances a country’s technological capabilities and prestige. Additionally, it contributes valuable scientific data and can spur advancements in related technologies, such as AI and robotics.
– Disadvantages: Space missions are costly and come with significant risk. Any malfunction could lead to the loss of the spacecraft and a setback in achieving the intended scientific objectives.
