Hi all -
I suppose that when we start to get decent IR images, this will be used to
explain the "dark comets", i.l. the dead comet fragments. Rationalizations work
in strange ways

Not to sound silly or anything, but there are meteorites with NO fusion
crust? Assuming of course you're not talking about very weathered
specimens, are you telling me there are freshly fallen meteorites that
have NO fusion crust at all? How is that possible?

No, there are not. There is a very small number, definable as the number of
planets and moons with an appreciable atmosphere. Are you suggesting that

the most mistaken concepts in our hobby so time for another treatise on fusion

it doesn't say how many will graze any given planet though. Unless of

I have thought what causes a fusion crust, but to be brief, I didn't explain
the obvious process of entry into an atmosphere and back out. To me, this
"skipping out" of the atmosphere is a relatively rare event. Most of anything
that enters the atmosphere in the first place burns up in the p

Yup it would be a guess, but doesn't science make guesses (hypotheses)
based on data and knowledge gained from data? Having said that, I think
it's safe to say there's more to it than meets the eye.

A fusion crust is formed by the rapid melting and rapid resolidifying of the
