In the US, if a meteorite lands on your property, it's yours and you can sell or donate it as you please. This homeowner probably made a decent amount on the sale, especially with the emphasis on immediate preservation.

Does this happen often in the US?
I mean often enough that folks happen to know the legality of it?
In which case I find it extremely frightening that one could be sitting on their porch, minding their own business, browsing HN, and then get unexpectedly head-shotted by a meteorite.

Everybody knows that. You contact NASA. Then a black helicopter will pick you up, bring you to an airbase and fly you straight to the white house, where you will be introduced to the actual truth, while a team of very excited scientists with biohazard suits praise and examine the artefact. If you're still sceptical, they will take you to a large hidden hangar in the middle of the desert and show you around.

I guess I'm not be reading the same type of science fiction.
You contact NASA because you found a meteorite with clear signs of alien life, a black helicopter will pick you up, you get put in a dark cell, interrogated, and then told to forget all about it or G-Men will disappear your family. You try to sell the news to mass media, but rumours start to spread about you. Your life work get discredited, you lose your job and family, end up wandering the streets in an alcohol daze muttering about aliens.
I guess it depends if you've drank the kool aid about the US government being the good guys, or not.

Can’t take any US action movie seriously anymore. Not because of plotlines like this, but because they portray the team at the white house as somewhat capable.

The real jackpot here is how this large chunk happened to impact a home belonging to an astute and prepared individual:
He then immediately preserved and documented the entire scene using disposable gloves and aluminum foil to place the meteorite fragments in glass jars.
I can think of many diverse reactions to a meteor strike, but even NASA is singing the praises of this guy and his quick thinking.

"Our cameras in Northford, Connecticut, and Douglassville, Pennsylvania, as well as a doorbell camera in Wayne, New Jersey, captured the meteor, and from that we measured its trajectory... The path traced back to low in the asteroid belt."
I don't doubt it, but that's an astounding trajectory estimation...
defrost 12 hours ago [-]
Desert Fireball Network, and less public precursor projects have been doing this for a while now:
> The dark flight trajectory of a meteoroid is significantly affected by the atmospheric winds, especially by the jet stream. As a result, the meteorite fall position can be shifted by up to several kilometers compared to a scenario with no winds.
That network is mostly interested in where it falls, not where it came from. A few degrees for finding an origin is a huge variation.
defrost 10 hours ago [-]
Planetary scientists are motivated to physically examine freshly fallen near pristine samples, yes. They are also keenly interested in origins, intra or extra solar system, relationships to known showers et al.
The less public precursors were and still have an interest in both projected targets and sources.
anovikov 11 hours ago [-]
This is absolutely trivial as long as any fixed ground objects are visible in a camera and does not at all require some sub-pixel precision.
onion2k 8 hours ago [-]
It's trivial to draw a line between some fixed points and extrapolate back to an origin if there's no external forces acting on the asteroid. But there is - planetary gravity, the moon, potentially the sun heating one side of it, atmospheric wind, weather, etc make a big difference. That makes it harder.
anovikov 8 hours ago [-]
That's basics of meteor observation. As long as camera didn't move, you can plot the track against the stars and time is known. Then with two tracks from different locations, orbit is determined.
lazide 7 hours ago [-]
Also, a typical consumer camera is going to struggle (even with the best analysis!) to have visual accuracy within even a few degrees of true (due to everything from high compression ratios in post processing to shitty optical properties in the actual camera) and that makes a probability cone that is pretty large.
Still better than nothing, though!
anovikov 5 hours ago [-]
building a WCS model (pixel XY <-> ray vectors) of a camera is a solved science. Of course you can never expect it to be rectangular.
lazide 2 hours ago [-]
No kidding, that is what I was referring too. Precision for a typical doorbell camera is going to be several minutes of angle at best, which is my point.

Oh well several arcminutes is excellent. Yes this is best case.

Are we sure the guy who picked it up didn't just wash it with some sort of detergent after it cooled off?
gus_massa 2 hours ago [-]
No, many of the the molecules are too unusual. More details:
The amino acids have a central C (Carbon) that is connected to 4 parts, a COOH (acid), a NH2 (amino) and H (Hydrogen) and a R (rest, that is a polite way to say whatever). [I'm ignoring some less usual cases.]
The 4 parts can be arengad in two ways, "L" and "D" that are mirrors of each other. Living things (and corpses) almost have only the "L" version. But in the meteorite they found a 50% and 50% mix of L and D that is a clear thing that they were made by chemical reactions instead of living thing.
Also, in living things (and corpses) the possible/usual R are like 30. The meteorite has a few of the usual ones, and also a few unusual ones that is another clear thing that they were made by chemical reactions instead of living thing.
Also, the R they found can be explained by the expected chemical reactions on a meteorite. I don't understand the details, but IIUC there is HCN (Cyanide) and in some conditions it likes to react with itself and make the stuff they found.
So unless the guy is a mad scientist making weird experiments in his attic that are not very useful to rule the word, it's probably a mix made in the meteorite by chemical reactions.
From what I understand about this story, the homeowner had the presence of mind to immediately attempt to preserve the meteorite, which is what made subsequent analysis possible.
Presumably other fragments landing outdoors with no one around taking similar steps to preserve them, even if they were to be recovered, would not be as valuable for study because of their exposure to the natural environment of Earth.

No? It's obvious the meaning is that most meteorites will never be found because they're tiny and no one witnesses where they land. If it hits a house you know where it landed.

Browsing that site, The SETI Institute appears to have expanded beyond its original goal of finding extraterrestrial intelligence into astrobiology and more. Perhaps the first attempts at detecting alien radio signals hoped too much?
I have little doubt that, given the infinite size of the universe, that extraterrestrial intelligence (of some sort) exists, the question is whether we will ever detect it... It perhaps even exists as close to us as Europa, should we attempt a landing there...

Detecting radio signals never made much sense to me.
Even a few light years away, it’s almost infeasible to build a radio transmitter that could be detected above the noise floor. The amount of energy you’d need would be absurdly wasteful.
