Arab Weather – Research has revealed that the moon has begun to rust, which surprised scientists, as there is no oxygen or water on the moon, which are the two main elements for the formation of rust, according to a CNN report.
In 2008, India’s Chandrayaan-1 lunar probe orbited the moon, collecting data that led to several discoveries, including the presence of water molecules on its surface. The probe also carried a NASA instrument to analyze the moon’s mineral composition.
When researchers at NASA and the Hawaii Institute of Geophysics and Planetary Sciences recently analyzed the data, they detected hints of hematite, a type of iron oxide known as rust. Although there are iron-rich rocks on the moon, rust formation requires exposure to oxygen and water.
“This is a great opportunity for us to be part of the future of space exploration,” said Abigail Freeman, a scientist at NASA’s Jet Propulsion Laboratory.
“At first, I didn’t quite believe it. It shouldn’t exist based on the moon’s special conditions.”
Not only is there no air on the Moon, but it is also flooded with hydrogen from the solar wind, which prevents rust from forming by adding electrons to iron.
“The moon is an unfavorable environment for hematite formation,” said Shuai Li of the University of Hawaii, the study’s lead author. After months of searching, Li and NASA scientists believe the answer lies on Earth.

One key piece of evidence is the concentration of rust on the side of the Moon that faces Earth, suggesting it is bound to our planet. Earth is surrounded by a magnetic field, and the solar wind stretches this field to form a long magnetic tail. The Moon enters this tail three days before it is full, and it takes six days to cross the tail and exit it.
During these six days, Earth’s magnetic tail covers the moon’s surface with electrons, which can cause strange effects. Dust particles on the moon’s surface may float off Earth, and moon dust may turn into a dust storm, according to NASA.
He pointed out that oxygen from Earth travels on this magnetotail to land on the moon, where it interacts with water molecules on its surface to form rust. Earth’s magnetotail also blocks most of the solar wind during a full moon, temporarily shielding the moon from hydrogen, opening a window for rust to form.
“Our hypothesis is that lunar hematite is formed by the oxidation of lunar surface iron by oxygen from Earth’s upper atmosphere, which is transported to the lunar surface by the solar wind when the Moon has been in Earth’s magnetotail for the past several billion years,” Li explained. “This discovery will reshape our knowledge of the Moon’s polar regions, and Earth may have played an important role in the evolution of the Moon’s surface.”

The Moon is Rusting, and Earth Might Be to Blame
A groundbreaking discovery has sent shockwaves through the scientific community: the moon is rusting. This revelation is particularly intriguing because the moon’s surface lacks oxygen and water, the two crucial ingredients for rust formation. So how is this cosmic phenomenon happening?
A Cosmic Mystery Unfolds
In 2008, India’s Chandrayaan-1 lunar probe, equipped with a NASA instrument, detected the presence of hematite, a type of iron oxide commonly known as rust. While the moon harbors iron-rich rocks, the absence of oxygen and water on its surface makes the existence of rust a perplexing enigma.
“This is a great opportunity for us to be part of the future of space exploration,” remarked Abigail Freeman, a scientist at NASA’s Jet Propulsion Laboratory. “At first, I didn’t quite believe it. It shouldn’t exist based on the moon’s special conditions.”
The Earth’s Magnetic Tail: A Crucial Clue
Scientists have long pondered the source of this lunar rust. The answer, they believe, lies in Earth’s magnetic field. The solar wind, a stream of charged particles from the sun, interacts with Earth’s magnetic field, stretching it out into a long magnetic tail.
The moon, in its orbit around Earth, passes through this magnetic tail. During this transit, Earth’s magnetic tail shields the moon from the hydrogen-rich solar wind, creating a window of opportunity for oxygen from Earth’s upper atmosphere to reach the moon’s surface.
“Our hypothesis is that lunar hematite is formed by the oxidation of lunar surface iron by oxygen from Earth’s upper atmosphere, which is transported to the lunar surface by the solar wind when the Moon has been in Earth’s magnetotail for the past several billion years,” explained Shuai Li, lead author of the study. “This discovery will reshape our knowledge of the Moon’s polar regions, and Earth may have played an important role in the evolution of the Moon’s surface.”
The Role of Earth’s Magnetic Tail
The concentration of rust on the side of the moon facing Earth further supports this theory. Earth’s magnetic tail acts as a conduit, transporting oxygen from Earth to the moon’s surface. This oxygen, interacting with water molecules on the lunar surface, triggers the formation of rust.
During a full moon, when the moon is completely within Earth’s magnetic tail, the solar wind is significantly blocked, creating an even more favorable environment for rust formation.
Unveiling the Moon’s Mysteries
This discovery offers a fascinating glimpse into the complex interplay between Earth and its celestial neighbor. It reveals that Earth’s magnetic field can have a profound and unexpected influence on the moon’s surface. As we continue to explore the moon, this finding opens up new avenues of research, inviting us to delve deeper into the moon’s history and evolution.
