The Historic Chang’e 6 Mission

Introduction

China’s space exploration efforts have reached new heights with the Chang’e 6 mission, which successfully returned samples from the moon’s far side to Earth. This groundbreaking mission marks a significant milestone in lunar exploration, as it is the first time material from the moon’s far side has been brought back to our planet.

Mission Overview

Chang’e 6, named after the Chinese moon goddess, comprises four modules: a lunar lander, a return capsule, an orbiter, and an ascender. The mission launched on May 3, 2024, and entered lunar orbit five days later. On June 1, the lander touched down in the Apollo crater within the South Pole-Aitken (SPA) basin on the moon’s far side.

The lander collected approximately 4.4 pounds (2 kilograms) of lunar material using a scoop and a drill. This precious cargo was then transferred to the ascender, which launched and docked with the orbiter. The samples were enclosed within the return capsule, which began its journey back to Earth around June 21. The capsule successfully landed in Inner Mongolia on June 25, 2024.

Significance of the Mission

The successful return of lunar samples from the moon’s far side is a historic achievement. Previous lunar sample-return missions by the Soviet Union, the United States, and China (Chang’e 5 in 2020) only collected material from the moon’s near side. The far side of the moon, which is more challenging to explore due to communication difficulties, remains largely uncharted territory.

The SPA basin, where Chang’e 6 landed, is a 1,600-mile-wide (2,500 kilometers) impact feature. Formed approximately 4.26 billion years ago, the SPA basin predates most other lunar craters. By analyzing the samples returned by Chang’e 6, scientists hope to gain insights into the early history of the solar system and the moon.

Scientific Objectives

The primary scientific objective of the Chang’e 6 mission is to study the SPA basin’s formation and its implications for the moon’s history. Understanding the timing and circumstances of the SPA basin’s formation could provide valuable information about the Late Heavy Bombardment, a period of intense asteroid and comet impacts in the early solar system.

According to the Planetary Society, “By obtaining precise dates for the basin and the craters overlying it, we will be able to better understand the moon’s history. This also has implications for understanding the origins of life on Earth. It’s possible that asteroids carried water and organic materials to Earth during the Late Heavy Bombardment.
