A recent study conducted by researchers from the esteemed Chinese Academy of Sciences and the Chinese National Space Administration has shed light on an upcoming mission called Chang’e-7. Scheduled for launch in 2026, this ambitious undertaking aims to unravel the mysteries surrounding water-ice in the moon’s permanently-shadowed regions (PSRs), with a particular focus on the lunar south pole. The findings of this study have been published in the prestigious journal Space: Science & Technology.
The Chang’e-7 mission is set to employ a multifaceted approach that combines both orbital observations and in-situ analyses. This comprehensive strategy will enable scientists to accurately determine the precise location, quantity, and distribution of water-ice within these enigmatic lunar regions. By leveraging cutting-edge technology and scientific expertise, the mission hopes to unearth valuable insights into the existence and characteristics of water on our celestial neighbor.
The significance of investigating water-ice in the PSRs lies in its potential implications for future lunar exploration. These permanently-shadowed regions are known to be extremely cold, with temperatures plummeting to as low as -233 degrees Celsius (-387 degrees Fahrenheit). Consequently, they serve as natural cold traps that can preserve volatile substances such as water-ice over extended periods. If substantial reserves of water-ice are indeed discovered, it could prove invaluable for sustaining future human settlements or supporting scientific endeavors on the moon.
To accomplish its objectives, Chang’e-7 will meticulously analyze data gathered through orbital observations. By scrutinizing the moon’s surface from above, the spacecraft will provide vital clues about the locations where water-ice may be concealed beneath the lunar regolith. Furthermore, the mission will utilize advanced instruments tailored for in-situ analysis, allowing for a deeper understanding of the composition and physical properties of the detected water-ice. These meticulous investigations will aid in characterizing the nature and potential accessibility of this critical resource.
The lunar south pole has been chosen as the primary target for this mission due to its intriguing geological features and the heightened likelihood of significant water-ice deposits. The region is characterized by craters that remain perpetually in shadow, shielding them from the Sun’s intense heat and radiation. These conditions create an ideal environment for water molecules to accumulate as ice. By focusing on this specific area, Chang’e-7 maximizes its chances of uncovering substantial reservoirs of water-ice, thereby contributing to our understanding of the moon’s geology and resource potential.
The forthcoming Chang’e-7 mission represents a remarkable step forward in lunar exploration, with its comprehensive approach poised to revolutionize our understanding of the moon’s water resources. By combining orbital observations and in-situ analyses, scientists aim to map the distribution and quantify the amount of water-ice hidden within the lunar south pole’s PSRs. This knowledge will not only enhance our understanding of Earth’s nearest celestial companion but also pave the way for future manned missions and scientific endeavors, bolstering humanity’s prospects of establishing a sustained presence on the moon.
