But the evidence was there.
As it is well known that iron's reaction to oxygen, which is both highly reactive metals, results in the formation of reddish rust, which is often found on Earth.
Although the Moon does not have an atmosphere, it does have tiny bits of oxygen present because of the Earth's magnetic field. "The moon is a bad environment for hematite to form".More news: Andy Murray knocked out of US Open
So, the presence of highly oxidized iron-bearing minerals, such as hematite, on the Moon is an unexpected discovery. So he turned to JPL scientists Abigail Fraeman and Vivian Sun to help poke at M3's data and confirm his discovery of hematite. Another factor is the presence of hydrogen in solar wind blasts the lunar surface.
After months of research, Lee and NASA scientists think they've cracked it - and the answer lies in our own planet.
Earth is encompassed in a magnetic field, and solar wind stretches this bubble to create a long magnetic tail in the downwind direction.
"Interestingly, hematite is not absolutely absent from the far-side of the Moon where Earth's oxygen may have never reached, although much fewer exposures were seen", said Li. "This suggested that Earth's oxygen could be driving the formation of hematite", Li says. The moon enters this tail three days before it's full, and it takes six days to cross the tail and exit on the other side.More news: Stephen A.

The magnetic tail also blocks nearly all solar winds throughout the moon - meaning the moon is temporarily protected from a hydrogen explosion, opening a window to rust.
When scientists at NASA and the Hawai'i Institute of Geophysics and Planetology evaluated the information just recently, they were shocked to discover tips of hematite, a kind of iron oxide referred to asrust There are a lot of iron-rich rocks on the moon- however rust is just produced when iron is exposed to oxygen and water. Lunar dust particles can fly off the earth, and moon dust can fly in a dust storm, According to NASA.
"This discovery will reshape our knowledge about the moon's polar regions", Li said. The heat from the dust particle impacts might also increase the oxidization rate. "Earth may have played a significant role in the development of the moon's surface". Humanity knows that there's no liquid water nor air to breathe on the cosmic object that revolves around our planet every day.
This theory could also explain why rust has been found in other air-free bodies such as asteroids.More news: The Witcher 3 is getting a free graphics upgrade with ray-tracing
To gather more data for these unresolved puzzles, NASA is building a new version of the instrument that has collected all of this existing data about the moon's mineral composition. One of the tools present on the spacecraft is the Moon Mineralogy Mapper, which can use hyperspectral imaging to perform an in-depth spectrocospic analysis that offers significant details about the chemicals found on the surface of the moon.
