【央视新闻】月球南极水冰稳定性研究取得新进展

Core Insights - The research team from the National Space Science Center of China has made significant progress in studying the stability of water ice in the Shackleton region of the Moon's South Pole, which is a candidate landing area for the Chang'e 7 mission [2][3] - A thermal stability model for water ice in the lunar polar regions has been developed, taking into account the thermal properties of lunar regolith under low-temperature conditions [3] - The study's findings, published in the journal "Planetary Science Journal," are crucial for understanding the distribution characteristics of water ice in the Moon's polar regions and will guide the Chang'e 7 mission's exploration efforts [2][3] Research Findings - The model calculates the stable distribution areas of sunlight, lunar regolith temperature, and volatile substances like water ice, which can be applied to analyze the thermal stability of water ice in the South Pole, particularly in the Chang'e 7 landing zone [3] - The research discusses the significance of water ice stability in terms of the ease of sublimation loss over long geological timescales, which is essential for identifying regions likely to preserve water ice [2][3] - The study emphasizes the importance of high-resolution thermal stability simulations for understanding surface radiation and temperature in the Shackleton region, which will aid in the precise remote sensing and in-situ detection of water ice by the Chang'e 7 mission [2][3]
