Lunar Meteorite Dust I One Gram - TOP METEORITE

Description

On Offer:
1 gram of lunar meteorite dust.
Official Name of the Lunar Meteorite:
NWA 14041
Lunar Meteorite Type:
Lunar Feldspathic Breccia
Year Found:
2021
Country:
Mali
Collection Method:
This lunar meteorite dust is isolated and collected from our specimen cutting process in a proprietary process created to ensure no other cutting residue is incorporated into the dust, and that the final recovered lunar material is as pure as possible.
The story:
Our Moon takes a lot of hits. This is evidenced by the millions of craters that cover the moon's surface. Thankfully the bombardments have slowed down considerably in the last few hundred thousand years, but they still do occur from time to time. Lunar meteorites are material ejected from our Moon's surface when it gets hit by a meteorite. If the impact has enough energy, some of the ejecta gets thrown so far it escapes the Moon's gravity becoming meteoroids hurtling through space. Some of those lunar meteoroids have the potential to eventually fall into Earth's gravity well and go screaming through the atmosphere to hit the surface. Once they hit the Earth's surface, they earn the designation of being a
meteorite
. Much later, perhaps thousands of years later, an even smaller fraction of the meteorites that didn't fall into the oceans or onto unrecoverable terrain, are recovered by nomads and others who happen to find them. Nothing short of miraculous odds. To describe them as rare, is perhaps an understatement.
