A Meteorite Field Trip To the Field Museum

A Meteorite Field Trip To the Field Museum

It has been many years since I last visited the Windy City so I jumped at the chance this spring when a conference presented just such an opportunity. While Chicago is not much more windy that New York City, and even less windy than Boston, it certainly didn’t disappoint, especially along the long waterfront walk […]

Tabor: My 262 year old Relative

Tabor: My 262 year old Relative

Twelve years ago, the Tabor Meteorite celebrated it’s 250th birthday on this planet. But to me Tabor is so much more than just a historical witnessed meteorite fall of advanced age. Tabor, Czech Republic is also the land of the people on my father’s side. In fact, there is no reason to think that my […]

Borodino: A Rock for the Ages

Borodino: A Rock for the Ages

The Borodino meteorite takes its name from the town of Borodino, Russia. Two days after the meteorite’s fall, the hamlet also extended its name to to the immensely bloody “Battle of Borodino.” For this installment of The Accretion Desk, I would like you do download and listen to the linked music file of Tchaikovsky’s 1812 Overture […]

Avanhandava, Brazil: A No-Nonsense H4

The distribution of Avanhandava is very low even though there are over nine kilograms in circulation. Avanhandava fell in San Paulo, Brazil in 1952. It is listed as an H4, S2, and despite […]

The single 880g mass was recovered shortly after it fell by Edward Keesling who “heard a hissing/buzzing sound, and then observed a dark object falling to the ground on the […]

69354 is the Zip Code for Mars[land]

In 1933, a 2.25kg meteorite was discovered in the community of Marsland, Nebraska. While not technically Mars, Marsland is, you have to admit, a pretty cool name for a meteorite even if only an H5. Marsland was not named after the wonderful Red Planet, but instead for Thomas Marsland, the general freight manager for the […]

Mbale: The First Digital Meteorite

For a brief period in August 1992, a meteorite fall captured the attention of those few on the planet who were enamored by such things. The shower of stones arrived at 3:40 in the afternoon creating quite a disturbance. One hundred fifty kilos of anything falling from the sky and landing on a town would […]
