在地月拉格朗日点L1建立天基气象观测站,监测地球磁尾对月球的影响

Space-based weather observatory at Earth-Moon Lagrange point L1 to monitor earth's magnetotail effects on the Moon

Saurabh Gore, Manuel Ntumba

摘要:

月球赤铁矿是由月球表面的铁被地球高层大气中的氧气氧化而形成的。月球表面不断受到来自太阳的太阳粒子的影响。然而,地球的磁尾阻挡了99%的太阳风,并提供了机会窗口,当月球处于满月阶段时,通过磁尾将氧气从地球的高层大气输送到月球。在这里,我们建议在地月L1拉格朗日点放置一个空间天气观测站,携带一个关键的有效载荷,以研究地球的磁尾如何导致月球表面生锈。空间天气观测站利用拉格朗日站的先进光谱传感器监测地球磁场对月球的影响。地月L1拉格朗日点是空间天气观测的关键位置,因为靠近该点的航天器几乎可以无障碍地看到月球。高阶解析近似所需的数值方法已经实现了更准确的预测。

英文摘要:

Lunar hematite is formed by the oxidation of iron on the surface of the Moon by oxygen from the Earth's upper atmosphere. The Moon's surface is continuously affected by solar particles from the sun. However, Earth's magnetic tail blocks 99 % of the solar wind and provides windows of opportunity to transport oxygen from Earth's upper atmosphere to the Moon through magnetotail when it is in its full moon phase. Here, we propose to place a space weather observatory at the Earth-Moon L1 Lagrange point carrying a crucial payload onboard to study how Earth's magnetotail causes the Moon's surface to rust. The space weather observatory monitors the effect of Earth's magnetic field on the Moon using advanced spectroscopic sensors from Lagrange-based stations. Earth-moon L1 Lagrange point is the key location for space-weather observation as spacecraft near this point obtains a nearly unobstructed view of the moon. Numerical methods needed for a high-order analytical approximation have been implemented for more accurate predictions.
