The LPSC deadline was yesterday, with the traditional flurry of activity and lots of science. Our abstracts are here. So much good science here! Excited for the virtual conference, but sad we all can’t gather in The Woodlands again this year.
Element maps
I’ve started adding X-ray element maps to our deep zoom meteorite mosaics. Acfer 182 is quite stunning. One can spend hours diving into the complexity of this meteorite.

Dog Sled Bolide: Upstate NY Dec 2 2020
One of the coolest bolide videos I’ve ever seen:
Katharina & Nan Interview
Mr. Toad meteorite
This is from Disney’s The Adventures of Ichabod and Mr. Toad (1949). Apparently a meteorite fell near a baby near The Wind in the Willows. I hope it is a CH3 chondrite!
A microscale search for cosmic answers
Fourth floor friend Seth Wood wrote this nice article for Wash U’s Ampesand about some of the work we do up here.
O-REX TAG
It was exciting to watch O-REX gather a sample from asteroid Bennu. One way OREX will determine how much sample was collected is by spinning the spacecraft and calculating the change in its moment of inertia before and after collection — a great basic physics experiment that I use as an example in my introductory physics class. The PI of OREX, Dr. Lauretta, got his Ph.D. at Wash U working with Dr. Fegley in EPS!
Acfer 182
Backscattered electron mosaic of the CH3 chondrite Acfer 182. This is a big one: ~160 gigapixels.
Bennu and Vesta
Very cool new paper on the discovery of chunks of asteroid Vesta on asteroid Bennu.
Our recent paper showed that pieces of carbonaceous-chondrite-like micrometeoroids bombarded Vesta’s regolith.
We should look through the carbonaceous chondrite multi-gigapixel BSE mosaics for clasts of HED-like material.
