Re: [meteorite-list] Destruction of the Hopewell civilization

[Mark Hammergren via Meteorite-list]

I, too, would love to hear more about the Hopewell people's use of
meteoritic materials.
As for the sensationalist article by Tankersley et al., it was convincingly
refuted by others and finally formally retracted from the journal this year.

Re: [meteorite-list] Terrestrial meteorite

[Mark Hammergren via Meteorite-list]

Thirty years ago, my thesis advisor, Don Brownlee, and I talked about
potential terrestrial meteorites and how their "asteroids" might be
identified among the population of near-Earth objects. Unfortunately for me
at the time, we decided that any strong identification would rely on
details of silicate chemistry that are tough to measure through
ground-based remote sensing. But we were certain that such bodies must
exist.

On the same subject, the moon will be a great place to search for
terrestrial meteorites, and may prove to be the best place to investigate
the conditions of early Earth. Heck, we might even find fossils.

Re: [meteorite-list] CNEOS1 2014-01-08 hunt in P.N.G. Harvard physicist Avi Loeb is organizing a $1.5 million expedition

[Mark Hammergren via Meteorite-list]

Agreed on all points. This is worse than nonsense: Avi Loeb and his
tabloid-quality antics make a mockery of SETI and astrobiology. Public and
congressional ridicule of a "search for little green men" doomed the NASA
High Resolution Microwave Survey in the early 90's. It would have surveyed
the sky in millions of frequencies using the Arecibo radio telescope,
partially for SETI purposes, and was already funded and running after a
decade of development. I worked with people who were employed in that
project and who had the rug pulled out from under their feet with
essentially no warning. Some had to leave the field of astronomy to find
other employment. Serious SETI research did not recover from that disaster
for more than 20 years.
What will Loeb advocate "studying" next? Chemtrails? HAARP mind control?
Qanon? Disgusting.

Re: [meteorite-list] Picric acid

[Mark Hammergren via Meteorite-list]

Metallic picrate salts are notoriously sensitive explosives, particularly
anhydrous nickel. Unless that is your desired end product, there are far
better choices for meteorite etchants.

Re: [meteorite-list] Falling Fireballs Crashed in Chile Last Week. They Weren't Meteorites

[Mark Hammergren via Meteorite-list]

Fires are never caused by meteorites or space junk, unless they are around
100 meters or so across. Did Chelyabinsk or Carancas start fires? No. We
have no evidence beside people seeing meteors and coincidental fires. Let's
put this to rest.

Re: [meteorite-list] MICROMETEORITES

[Mark Hammergren via Meteorite-list]

Dan,
Essential references for hands-on work on this topic are two books by
Jon Larsen, both available from Amazon and other sellers at extremely
reasonable prices. These are: "In Search of Stardust: Amazing
Micrometeorites and Their Terrestrial Imposters", which has stunningly
beautiful microphotography, and "On the Trail of Stardust: The Guide
to Finding Micrometeorites: Tools, Techniques, and Identification".
Best of luck to your friend!

Re: [meteorite-list] Meteorites Recovered From Ocean Bottom

[Mark Hammergren via Meteorite-list]

Hi Rob,
Excellent question! We've been working on a recovery effort for the
Feb. 6, 2017 Wisconsin / Lake Michigan meteorites since shortly after
that fall. Marc Fries is part of this collaboration between the Adler
Planetarium, Field Museum, and Shedd Aquarium to retrieve fragments of
these meteorites using a magnet-equipped underwater sled, with some
reconnaissance using small ROVs. The predicted spatial density of
large fragments is pretty low, but we're hopeful that we can find some
of the more numerous tiny fragments that are certainly out there. The
project is being implemented primarily through the work of our teen
volunteers and interns -- mostly because involving the public in our
work is what we do, but also because nobody funds scientists to hunt
for meteorites (ANSMET being an exception).
The nature of the lake bottom is quite varied, and largely unmapped
throughout the strewn field. While there are significant stretches of
clean sand and silt, there are also outcrops of bedrock, colonies of
zebra and quagga mussels, and at least two known shipwrecks. Hopefully
no great amount of taconite pellets from the northern iron mines!
You can learn more about "The Aquarius Project" at:
https://www.adlerplanetarium.org/education/far-horizons/the-aquarius-project/
Best regards,
-- Mark

Re: [meteorite-list] space junk

[Mark Hammergren via Meteorite-list]

I'd hazard that this is lightning damage, and the vitreous slag-like
material is the remains of the melted shingles. There are some
fragile-looking drips on the large fragment in image 4 that don't look like
they could have survived high-speed impact through the roof. A Google image
search for "lightning damage to roof" also shows similar holes in shingle
roofs.

Re: [meteorite-list] Very Very cool Meteor video

[Mark Hammergren via Meteorite-list]

I'm sorry, but this is a terrible fake. One big red flag: why would he
compose the shot pointing the camera to a boring, cloudy scene --
precisely where the "meteor" would come down? And another: the time
delay between the "meteor" and sonic boom is less than around five
seconds, corresponding to a distance of around a mile or so to the
fireball itself! Not realistic at all.
