Author name: Martin Horejsi

Dr. Martin Horejsi is a Professor of Instructional Technology and Science Education at The University of Montana, Missoula. A long-time meteorite collector and writer, before publishing his column "The Accretion Desk" in The Meteorite Times, he contributed often and wrote the column "From The Strewnfields" in Meteorite Magazine. Horejsi is also the Lead Technology Reviewer for The National Science Teaching Association, and just celebrated his 22th year working with NASA and the JPL in education and public outreach (EPO), and is a NASA Solar System Ambassador. Horejsi specializes in the collection and study of historic witnessed fall meteorites with the older, smaller, and rarer the better. Although his meteorite collection once numbered over a thousand pieces with near that many different locations, several large trades and sales and trades have streamlined the collection to about 250 important locations with all but 10 being witnessed falls. Many of the significant specimens in Horejsi's collection are historic witnessed falls that once occupied prominence in the meteorite collections of Robert A. Haag, James Schwade, and Michael Farmer. Other important specimens were acquired through institutional trades including those from The Smithsonian Institution, Arizona State University, and other universities. Horejsi was awarded the Harvey (Nininger) Award in Tucson in 2006, The Brotherhood of Guardians of the Ensisheim Meteorite in 2011, a JPL Inspiration Person, on the JPL STARDUST Team that was awarded the Smithsonian Air and Space Museum Annual Trophy in 2008, and former board member of the International Meteorite Collectors Association, and the Northwest Council for Computers in Education.

Meteorites at the Rock Shop: Columbine of Aspen is Breathtaking!

  For those of us with an above average enthusiasm for meteorites, the traditional rock shop is often devoid of the very rocks we crave. Yet we continue to search their offerings in hopes a space rock somehow entered their inventory. And when desperation finally sets in, we resort to asking the question of the proprietor, “Do you have any

“I’ll Be Back” and East Coast Meteorites: Remembering 30 years ago with Peekskill.

About 100 miles separates Titusville, NJ and Peekskill, NY. So why does that matter? Well in 1992, those of us who got excited about meteorites back then were able to follow the events surrounding the fall of the Peekskill meteorite. And the Peekskill meteorite was preceded by the Peekskill fireball that was captured by no less than 16 video cameras.

H. H. Nininger: Master of Meteorites By Kenneth J. Zoll

From 1889 to 1923, Harvey Harlow Nininger followed the fairly traditional and well worn path of an academic, but then something changed. And very likely if you are reading this, you also have experienced that “change” and from that point on, meteorites were part of your life. In the case of H. H. Nininger, he took the rest of the

Old Woman’s Knee, Ron N. Hartman, and NWA 400 Meteorites

As I was doing some spring cleaning during our first Montana winter blizzard, I found a bag of meteorites labeled at Oum Rokba. Further, there was a polished complete slice with an accompanying specimen card from the Ron Hartman collection. It gave me pause since I knew Ron Hartman had passed on over a decade ago, and Oum Rokba was

Artemis and the Valera Meteorite: Time to get back to work!

A strange thing about the Valera L5 meteorite, besides landing on a cow of course, is that it is currently crossing the bridge of time between recent and historic. October 17, 2022 marks the 50th anniversary of its fall to earth. That timespan is also the physical distance between our last visit to the moon, and our renewed interest in

John Shaw and the Tagish Lake Meteorite: “Boy, that was close!”

The 21st century began with a bang over Alaska and Canada. Just over two weeks into the new millennium, an amazing specimen of carbonaceous space science landed on a frozen surface preserved about as well as anything could have been outside crashing through the roof of the Lunar and Planetary Lab at Johnson Space Center during a tour by top

Bensour: The Meteorite Times Birthday Meteorite

Of all the different directions and angles of collecting rocks from space, the so-called Birthday Meteorite is the most personal. And due to the fact that meteorite falls, finds, and of course distribution and collector access, the offerings to those desiring a particular meteorite are not predictable. A Birthday Meteorite, at least according to my unofficial definition, is a meteorite

Within the sovereign borders of Ukraine, over 40 meteorites have been discovered with many of them witnessed falls. Many of them now also considered historic falls and finds, with many of those also rare types. And luckily, many available for our collections. My personal collection contains about 10 different Ukrainian meteorites specimens, and at one time many more when I

The Forest City Meteorite: When Science Took a Backseat to Litigation

Iowa, as a state, joined 28 other others back on December 28, 1846. And late that same century, as Frank Cressy wrote, “Over a 15 year period in the late 1800s, the state of Iowa experienced three of the largest meteorite showers in the history of the United States.” One of those falls was named Forest City, and it was

New Orleans revisited. Where is the meteorite? Either one?

One year ago we lost Dave B. Gheesling, one of the greats in this gentlemanly art of meteorite collecting. Dave valued friendships and made it obvious with his vast collection of pictures with meteorite friends. So take a moment and see the big picture on Dave’s Falling Rocks website filled with friend photos. Back to New Orleans… On September 23,

Turbid Glass from a King: The Ipiranga Brazil Meteorite

Two days after Christmas back in 1972, a meteor headed west across the sky over southwest Paraná State in Brazil. Described as an “airplane on fire” and a “flying torch” the bright light broke up and left a trail of smoke that floated in the cloudless morning sky for more than 15 minutes. Machine guns came to mind to those

The Allegan, Michigan Meteorite: A Confused Agglomerate

On a summer morning at about eight o’clock, a large stone meteorite entered the airspace above Allegan, Michigan landing on a spot of ground known as Thomas Hill. It was Monday July 10, 1899. The Allegan meteorite is classified as an H5 chondrite, one of the most common types of meteorites to fall on this world. But what seems like

Sorry it took me 213 years to show you my Stannern Meteorite Individual

Two hundred and thirteen years ago this May, the Stannern achondrite fell from the sky, landing in what is now the Czech Republic. The shower of stones was reported to have lasted eight minutes which I find astounding for many reasons. Estimates of upwards of 300 individual stones fell with only 66 documented stones recovered, and a majority of those
