Overview

The Chang’e 6 mission is an ambitious undertaking by the China National Space Administration (CNSA) to explore the enigmatic and scientifically significant far side of the Moon. Scheduled for launch in 2025, the mission aims to collect lunar samples from the South Pole-Aitken (SPA) basin, the largest and oldest impact basin in the solar system.

Objectives

The primary objectives of the Chang’e 6 mission are:

To collect lunar samples from the SPA basin.
To investigate the geological composition and evolution of the far side of the Moon.
To search for volatiles, such as water ice, in the permanently shadowed regions of the SPA basin.

Mission Profile

The Chang’e 6 mission consists of three main components: a lander, a rover, and a return vehicle. The lander will touch down on the far side of the Moon in the SPA basin and deploy the rover. The rover will then explore the area, collect samples, and transmit data back to Earth. The return vehicle will collect the lunar samples from the rover and return them to Earth for analysis.

Scientific Significance

The Chang’e 6 mission is expected to make significant contributions to our understanding of the Moon. The samples collected from the SPA basin will provide valuable insights into the early history and evolution of the Moon. The mission will also search for volatiles, such as water ice, in the permanently shadowed regions of the SPA basin.

China National Space Administration’s Chang’e Program

The Chang’e Program, initiated by the China National Space Administration (CNSA), is an ambitious lunar exploration program aimed at studying the Moon’s surface, composition, and potential resources. The program consists of a series of unmanned missions, including:

Chang’e 1 (2007): Lunar orbiter mission to map the Moon’s surface and study its mineral composition.
Chang’e 2 (2010): Lunar impactor mission to investigate the Moon’s surface and prepare for future soft landings.
Chang’e 3 (2013): Lunar lander and rover mission that successfully landed on the Moon and conducted scientific experiments.
Chang’e 4 (2019): Lunar lander and rover mission that achieved the first soft landing on the Moon’s far side, a region previously unexplored by humans or robots.
Chang’e 5 (2020): Lunar sample return mission that collected and returned lunar regolith to Earth for scientific analysis.

Chang’e 6 Landing Site Selection on Far Side of the Moon

China’s Chang’e 6 lunar mission aims to land on the far side of the Moon. The candidate landing sites are located within the South Pole-Aitken (SPA) basin, which contains geological features of significant scientific value.

A team of scientists evaluated potential landing sites based on various criteria, including terrain roughness, slope, rock abundance, and proximity to scientific targets. They assessed each site using high-resolution images and topography data from previous missions.

After thorough analysis, two landing site options were identified: a site near the Von Kármán crater and another near the Leibnitz crater. Both sites offer access to diverse geological environments, including fresh craters, ancient ejecta, and potential lunar mantle materials.

The final selection of the landing site will depend on further detailed analysis and risk assessment. The Chang’e 6 mission is expected to provide valuable insights into the Moon’s geological history and evolution, contributing to the advancement of lunar science.
