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

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

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

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

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

Re: [meteorite-list] Picric acid

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. On Sun, Jan 15, 2023, 12:52 PM John Lutzon via Meteorite-list < meteorite-list@meteoritecentral.com> wrote: >

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

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. On Fri, Aug 14, 2020, 9:37 PM Paul via Meteorite-list <

Re: [meteorite-list] MICROMETEORITES

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

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

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

Indeed, you should run! It's a modified water truck used for cleaning rail hopper cars, and you might get soaked! http://www.daltontrucking.com/mom-whats-that-for/ On Dec 9, 2017 2:00 PM, "Adam Hupe via Meteorite-list" < meteorite-list@meteoritecentral.com> wrote: > If you see this show up in

Re: [meteorite-list] space junk

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

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

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
