Iron particles found on the moon and bought back to earth exhibited a strange characteristic. What was it?

Answer 1

The iron particles were rust proof.

Answer 2

I don't think the particles of iron were all that unusual. A particle is a rather small unit to be displaying strangeness, especially for iron, where a particle would be only a single atom.

Iron found on the moon was probably rather rare, since the moon itself is Iron poor, most of it probably came from meteorites and asteroids that had hit the moon.

Iron from these sources are usually made of a nickel-iron alloy. When the meteorites hit the moon, the particles would be melted, and thrown in all directions, making for lots of tiny droplet shaped pieces of iron.

Larger chunks may have remained unmelted. These chunks of asteroids often contain an odd property of iron, known as "Windmanstatten" patterns. If iron is allowed to cool very slowly, like over thousands of years, it will crystalize, just like water turning to ice. The crystalization produces the windmanstatten patterns, which you have to cut the iron apart, and polish it down to see.

Answer 3

Much of our knowledge of the space weathering process comes from studies of the lunar samples returned by the Apollo program, in particular, the lunar soils, or regolith. The constant flux of high energy particles and micrometeorites, along with larger meteorites, act to comminute, melt, sputter and vaporize components of the lunar soil, as well as to garden (or overturn) it.

The first products of space weathering that were recognized in lunar soils were agglutinates. Agglutinates are created when micrometeorites melt a small amount of material, which incorporates surrounding glass and mineral fragments into a glass-welded aggregate ranging in size from a few micrometers to a few millimeters. Agglutinates appear black to the human eye, largely due to the presence of nanophase iron. Agglutinates are very common in lunar soil, accounting for as much as 60 to 70% of mature soils.

Space weathering also produces surface-correlated products on individual soil grains, such as glass splashes; implanted hydrogen, helium and other rare gases; solar flare tracks; and accreted components, including nanophase iron. It wasn't until the 1990s that improved instruments and techniques allowed for the discovery of very thin (60-200 nm) patinas, or rims, develop on individual lunar soil grains as a result of the redepositing of vapor from nearby micrometeorite impacts and the redeposition of material sputtered from nearby grains[1]. These weathering processes have large affects on the spectral properties of lunar soil, particularly in the UV/Vis/NIR wavelengths.

Answer 4

The particles did not speak a recognizable language.

Seriously, though, it was probably that they wouldn't rust. And if they did... then where did that oxygen come from?

Answer 5

it was a fake iron

Answer 6

no one has ever been to the moon. its a LIE!
