背景知识
近日，科学家在月球表面发现了一件奇怪的事情，在月球两极的岩石中存在铁锈。“生锈”是一种化学反应，需要氧气和水才能自然发生，而月球上完全没有氧气。科学家们正在试图找出月球“生锈”的原因。这件事情的起因，是一名科学家——李帅，在《科学进展》（Science Advances）上发布了一项新研究。李帅从印度太空研究院的“月船一号”（Chandrayaan-1）轨道器获取数据，发现月球两极的岩石与月球其他地区的岩石组成不同。经过进一步的观察，他发现了赤铁矿，一种常见的氧化铁——铁锈。

The moon is ‘rusting‘ and scientists are stunned
A newly published study notes that the moon is “rusting,” leaving experts perplexed by the discovery. The research, published in Science Advances, notes that the rust may be a result of water discovered on the moon, but it’s still shocking, given the lack of oxygen and dearth of water on Earth’s celestial satellite. “It’s very puzzling,” the study’s lead author, Shuai Li of the University of Hawaii, said in a statement.
“The moon is a terrible environment for hematite to form in.” Li was looking at data from the JPL Moon Mineralogy Mapper when the researcher realized the instrument detected “spectra – or light reflected off surfaces – that revealed the Moon’s poles had a very different composition than the rest of it,” the statement added. The polar surfaces showed spectra that matched the mineral hematite (Fe2O3), according to the study’s abstract.
With no atmosphere providing oxygen on the moon and the sun’s solar wind delivering hydrogen — which should act as a “reducer” to prevent oxidation — scientists are baffled where the rust is coming from. However, they believe it could stem from Earth, given the moon does have “trace amounts of oxygen” thanks to Earth’s magnetic field. The hematite that was discovered is not near any of the water ice that has been discovered so far on the moon, adding another layer of complexity to the findings.
