Westcoin I Accept Your Challenge!

@chafemaster hopefully more people will post theirs. I can't believe I have Neil Armstrong and Buzz to look at. Apollo spacecraft in stunning detail. Lucky girl.

wow that is some collection that is amazing I do not need another hobby lol

Actually, that is an incredible collection of rocks possibly blasted off Mars or during our showers. The Pleiades, etc. The actual value of those is probably beyond my ability or reason. They spent Billions of years in space and you have them.

I remember my buddy at the old Telescope shop had an actual piece of the moon, not a moon rock (as those are closely held and controlled by NASA) but a fragment of the moon from when a large meteor hit it, it wasn't very big at all and valued around $5K. He also had one of the Mars rocks. But nothing as nice as your display hfjacinto, that's like a museum masterpiece display!

Thanks Westcoin but my little display doesn't come close. This is the vault at ASU, this is a museum quality display. Sadly very few people have gone to the vault, it was nice touching a 150 gram piece of Mars.

It's really easy, the rocks from space have no characteristics like terrestrial rocks, we have no 90% iron /10% nickel rocks on earth, but there are other characteristics which make meteorites different.

For example fusion crust from traveling through the atmosphere.

Pallasites have crystals of peridot.

All irons have a Widmanstätten pattern since they cool so slowly in the vacuum of space metal crystals form.

On Stony meteorites you have chondrules which are round gatherings of material.

While some terrestrial rocks look like meteorites they don't have all the characteristics of a meteorite.

I think all rock on Earth are Ignious or Magnetite. A process of volcanic activity. These treasures are from the birth of the Solar System and are asteroidal and didn't suffer the accretion and processes that formed the fantastic rocky Iron cored miracle we called Earth. We really should have called it something nicer. There is a hill near my flat called Falkland Hill and another we call Devils Plough because it looks like it was smashed in half by the devil.
Both are ancient volcanoes.
Pristine meteors are time machines 4.5 Billion years old as the system formed.
Stranger still is Sol. A Main sequence type G star on it's own is very unusual. Normally stars are at least binary, often 4 or more. She's on her own and super stable.
Hey am often wrong so get a second opinion.

I've been to ASU a few times, never saw that part, I was always either in the stadium shooting a football game or underneath it visiting the Richard F. Caris Mirror Laboratory.
