摘要

关于月球外逸层的起源和形成的重要方面,其脆弱的气体包层,仍然令人困惑,关于不同影响的重要性的不确定性。两个相互竞争的过程——微流星体撞击汽化和太阳风离子溅射——被认为是将粒子喷射到外逸层的关键因素。在这里,我们使用真实的月球样本(阿波罗16号样本68501),结合先进的风化层侵蚀3D模拟,提出了直接、高精度的太阳风离子溅射产率测量。我们发现太阳风溅射的产量比以前使用的外逸层模型要低一个数量级。这种差异主要是由于表面形态的抑制作用,特别是月球风化层的粗糙度和高孔隙率。我们的研究结果提供了关键的、经过实验验证的溅射产量估计,并解决了长期存在的建模不确定性。鉴于即将到来的和正在进行的任务,如月球上的阿尔忒弥斯计划或水星上的比皮可伦坡计划,这些结果特别及时,从本质上有助于我们了解太阳系中岩石体的表面是如何改变的。

Solar wind erosion of lunar regolith is suppressed by surface morphology and regolith properties.

Solar wind erosion of lunar regolith is suppressed by surface morphology and regolith properties.

Important aspects concerning the origin and formation of the Moon's exosphere, its tenuous gas envelope, remain puzzling with uncertainties regarding the importance of different effects. Two competing processes - micrometeoroid impact vaporization and solar wind ion sputtering - are considered key contributors to the ejection of particles into the exosphere. Here we present direct, high-precision yield measurements of solar wind ion sputtering using real lunar samples (Apollo 16 sample 68501), combined with advanced 3D simulations of regolith erosion. We find solar wind sputter yields up to an order of magnitude lower than previously used in exosphere models. The difference is primarily due to the suppressive effects of surface morphology, in particular the roughness and high porosity of the lunar regolith. Our results provide critical, experimentally validated sputter yield estimates and address long-standing modeling uncertainties. These results are particularly timely in light of upcoming and ongoing missions, such as the Artemis program at the Moon or BepiColombo at Mercury, contributing essentially to our understanding of how the surfaces of rocky bodies in the solar system are altered.
