Not necessary. This is because you are not a scientist Keith.
Otherwise you would know that humans never landed
on Sun and other distant stars (at least officially) but
its material compositions are known from spectroscopy data.
Some elements (helium for instance) were first discovered on
Sun and only after that was found on Earth.

Spectroscopy will tell you what elements are present and in what
proportions but can tell you nothing about the structure of the
objects themselves. Diamond, graphite and hard coal all show
up as carbon in a spctroscopic analysis.

So what?


But you know this Michael so you seem to be being somewhat
less than wholly truthful.


100% truthful. NASA had tons of meteorites of different type.
only from ANSMET program NASA got some 10000 Antarctic meteories
Spectroscopy data were good enough to separate lunar rocks from that
stock. BTW lunar meteorites have no single structure. It can be
as different as basalts and breccias.


Ansmet started in the year 1976, how do you propose
NASA accessed its findings back in 1969 ?

If one have reliable markers it was easy to separate lunar
meteorires from the rest and to know "what any sane person
would expect"


And the reliable markers were of course obtained by the Apollo samples
