The Moon is totally metal

  • New readings from NASA’s Lunar Reconnaissance Orbiter reveal that the metal content within lunar craters is significantly higher than on the surface.

  • The findings could reveal a new link between the Moon and Earth and support formation theories.

  • Ongoing research will be directed at craters in different areas to determine if the trend is consistent across the Moon.

    When you look at the dusty white and gray surface of the Moon it’s hard to know exactly what you’re looking at. Here on Earth, the surface is covered in much more colorful soil, sand, or rocks. So what is the Moon’s pale surface hiding? According to new research conducted by NASA’s Lunar Reconnaissance Orbiter, there’s apparently a lot more metal on the Moon than was previously thought.

    The LRO is a pretty amazing piece of equipment, and it’s equipped with a radar that not only reveals some of the interesting geographical features of the Moon’s surface but can also offer a hint as to what is lying beneath. NASA says that new evidence points to higher levels of iron and titanium than scientists had realized.

    The research, which was published in the journal Earth and Planetary Science Letters, focused on readings taken from scans of large craters on the lunar surface. These impact craters have the capacity to reveal what the Moon is truly made of deep down and offer researchers information that could hint at its origins.

    “Substantial evidence points to the Moon as the product of a collision between a Mars-sized protoplanet and young Earth, forming from the gravitational collapse of the remaining cloud of debris. Consequently, the Moon’s bulk chemical composition closely resembles that of Earth,” NASA explains. “Look in detail at the Moon’s chemical composition, however, and that story turns murky. For example, in the bright plains of the Moon’s surface, called the lunar highlands, rocks contain smaller amounts of metal-bearing minerals relative to Earth.”

    1. So I'll name my next heavy-metal band "Lunar Dust"....

    Very interesting! (as always from Judi Lynn--I don't know how you find all this stuff, let alone post it! But we greatly appreciate it!)
