Several fragments of the meteor that fell in South Texas on Feb. 15 had been not too long ago recovered. Some of the meteorite hunters are members of the American Meteor Society, a company that tracks most of these fireball occasions and publishes information so meteorite hunters have a greater thought of the place to go looking. Mike Hankey, operations supervisor of the American Meteor Society, spoke with TPR’s Jerry Clayton.
This interview has been edited and condensed for size and readability.
Clayton: On common, what number of objects like this one which fell in Texas enter the Earth’s ambiance?
Hankey: This was a much bigger than regular meteor. So perhaps of this dimension, perhaps it is like as soon as per week on the globe. This is an enormous occasion. There’s little question about it.
Clayton: So what do we all know to this point about this fall that occurred in Texas?
Hankey: So that is really a really fascinating meteor that occurred in Texas [because] it was a part of a triplet of occasions that occurred over three completely different days in three completely different international locations. The first one was in France. There was an asteroid that was really detected a couple of hours earlier than it impacted Earth by telescopes, and that created loads of pleasure.
There was one other occasion the very subsequent day in Italy, the place a fraction of a meteor … hit the bottom and was found straight away.
And then the following day was this Texas occasion. [It] occurred through the daytime. It was nonetheless gentle exterior, which additionally makes it a bit bit particular.
It occurred on the tenth anniversary of the Chelyabinsk meteor … in Russia. It was the biggest meteor that is hit Earth in 50 years. And it blew up above the town and prompted all of those home windows – 2000 home windows had been [smashed], and folks went to the hospital.
Clayton: How troublesome was it to pinpoint the realm the place these objects fell in South Texas?
Hankey: It was narrowed down fairly nicely by a system of Doppler climate radar that the United States authorities has that is accessible to everybody. It goes out on the NOAA web site. …
The actually exhausting half is figuring out the place in the radar to look, what time and what location do you wish to search for this signature. But while you do discover it, the meteorites are just about proper beneath the Doppler radar. And that is the case right here. And that is occurred a few dozen instances in the U.S. during the last ten years.

Clayton: What sometimes occurs to those fragments after they’re recovered?
Hankey: Say, a meteorite hunter goes to wish to have it labeled, which implies that you must donate a share of it to scientific establishments. They do these checks. They do these analyses. They find yourself figuring out the kind of meteorite that it’s, and so they write up a bit paper that will get put right into a database. That course of has solely occurred about 1,400 instances in the historical past of humankind.
So most of these meteorite recordsdata are very uncommon. They do not happen fairly often, and they’re dealt with in a particular technique to document them from there. Some materials could be studied, however most of it will be bought in collectors markets. It’ll be damaged up into smaller fragments.
I’m positive this one goes to have a number of research finished past simply the classification as a result of they will at the very least be trying in to see if it is associated to those different meteorites that occurred not too long ago. Some go into personal fingers, some go to establishments and so they’re studied.
