Thank you for responding to my questions. I am also trying to gain a
self-meteoriticized education. I was unaware of the attachment rule.
PS - Attachments aren't supposed to be posted to the list, per list

Hi Randall:
I will try to answer one of your questions.
I wish I could give you details on how to get meteorites off of Mars, but
this is something that I would have to talk to Jay Melosh about (if I can
keep him in place long wnough).
However, I can address the issue of asteroid/meteroid
Could your Martian impact scenario apply to ejecta
from Mercury?
Probably but you've no atmospheric effects to account
for.
You've got a big potential well to climb out of mind.
Fine, you've got the Yarkovsky effect to help you out
but it's a big ask. I don't know where I read this or
Ken,
Thank you for you reply and the link to webwrongs. Yes, it's theolitic basalt
with a melted surface. I hope you will keep an open mind and take the time to
read this. Please take a look at the Geophysical Meteors on the web link you
provided.
I have had many communications with
Another way to recognize a Venus surface rock would be from
its weathering in the Venus atmosphere. Because Venus'
surface is so hot, and its atmosphere is so rich in carbon dioxide
and sulfur oxides, the surface rocks should have lots of sulfates
and maybe carbonates in them. Water-free sulfates

Ken,
I will be happy to share with you some of the data that I've collected at the
impact site including videos and pictures. All of the pictures, videos, and
samples are stored at my apartment in Lima. I am currently in Arequipa and
expect to travel to Lima within the next two weeks.
Mr. Webb,McCafferty and others.
If you don't mind, I have a few more questions.
Do you know of a facility that could perform 187Os/186Os ratios testing at
a reasonable price?
Would element variations and ratios in the fusion crust be indicative of
extraterrestrial origin.

I believe Fermat wrote something the same thing and it

Randall,
I think we would all be interested in seeing photos of the crater you
found and your suspect meteorites rather than the roundabout way you
began this discussion. As to whether anyone can assist you, depends if
you are seeking truth or a preconceived idea.

Hi Randall and Others:
I did some checking. To quote Tim Swindle: Yes, there may be meteorites
from Venus, but we have not found them yet!
It is much more difficult to get something out of the gravity well of
Venus, through the Venus atmosphere, and out of the gravity well of the
Sun. It is much

Hi Randall and the List,
This guy has spent a lot of time testing his rocks.
His samples look very terrestrial to me. I do not
recognize any flight markings.
He states that the escape velocity of Venus is less
than Earth, but he does not explain how an impactor
makes it to the surface
Has anyone seen this website and if so, what are your opinions as to the
validity of his claims that the meteorites found are from Venus. And how would
anyone know if a meteorite came from one of the inner planets? Would cosmic ray
exposure and oxygen isotope be useful. What tests would be
