I have to give credit to these scientists for taking on such an arduous journey to find the point of impact.Siberia is a huge country(you can fit Canada within the borders of Siberia and still have room left over) and much of the landscape is just about impassable by conventional means.And if that isn’t hard enough,the mosquitoes and various fly species will eat you alive in summer months.Winter is downright freezing with temps bordering on minus 50 Fahrenheit.I first learned of this event as a teenager 40 some years ago.Thanks for the upload.

Most of the information found online for the past few decades has mostly been hyperbole and wild speculation about what happened in Tunguska. This miraculous documentary tells the complete scientific history of the event and how it was studied, in clear detailed terms. Thanks for posting. I once had an eight ounce individual piece of the Sikhote Alin meteorite, which I regrettably sold ten years ago. It was not “shrapnel” and had the best features possible.

The video was originally digitized by David Kring (currently at LPI-JSC) and a copy was sent to John Wasson at UCLA. I found it among John's effects after he passed away. From what I was able to find out, David and John had hopes of releasing the video around 20 years ago, but were unable to, due to questions about copyright. The music was copyright claimed so I'll never see any revenue from it, but I still thought it was worth sharing. There's no real drawback to posting copyright-claimed content on KZfaq - I'd just never see any ad revenue from it, but this channel isn't monetized, anyway.

@@user-tj7tq9jt2i Cometary is definitely possible, but I don't think I'd make such concrete statements. There's no hard line between objects like D-class asteroids and comets, so I'd hesitate before saying it was a comet versus something like a friable CI-chondrite like asteroid or even an object similar to 2008 TC3 - just larger. It's very possible that recoverable meteorites fell. It took 13 years for the first expeditions to arrive - if the object was something like a CI chondrite, any meteorites that survived to reach the ground would have turned to mud within, at most, a few months. If they were a more durable type...it's still possible that they're there to be found, but haven't been recovered yet. The dynamics of the explosion are still very much a subject of ongoing work, and modeling a potential strewnfield for an event like this, even today, is educated guesswork. NASA's models for the Muskogee, Oklahoma, fall just a few years ago were off by several miles. If you look in the wrong spot, you have no chance of finding anything... Even with good intel, hunting for a decades-old fall in a literal swamp would be extremely challenging, and finding any fragments would be remarkably lucky. I'm not convinced either way.

@@prevost8686 An icy meteorite would be a comet by definition. The trouble is that small objects in the Solar System aren't just all rock or all ice - there's a gradient. Active comets tend to be very icy, but many asteroids look like comets that have gotten trapped in the warm inner Solar System and have lost most of their water / ice. But they're still very soft and would act similarly when coming into the atmosphere. Based on how the Tunguska object ~exploded, we know it was friable, but that's all I'd say we know for certain. It could have been cometary / icy. It could also have just been a soft/wet asteroid, like a CI1 chondrite.

Our best guess is that it was a very "soft," comet-like asteroid. A few similar but smaller events like Revelstoke (fell in Canada in 1965) have been documented and a little material has been recovered. Revelstoke was identical to a rare type of meteorites we have other samples of called CI chondrites. They are very friable, clay-rich meteorites -- spectrally similar to B and D-type asteroids like the asteroid Bennu, which OSIRIS-REx just sampled. When modeling the atmospheric entry of soft bodies like this, if they are large enough, they tend to punch through the upper levels of the atmosphere and then explode catastrophically when ram pressure builds high enough. Most meteorites are much more coherent and are better at surviving fragmentation. I've been trying to come up with a practical analogy -- it's like the difference between dropping a rock off of a high bridge versus a bag of flour: The rock will probably survive hitting the surface of the water. The bag of flour will probably ~poof. There is a good chance that the Tunguska event dropped at least some recoverable CI-chondrite meteorites. Unfortunately, CI chondrites react rapidly with water and decompose into ~mud. A CI chondrite would not survive for more than a year or two if left exposed to the wet climate of the area. The Tunguska event was in 1908 and the first expedition made it to the area only by 1927, 19 years later. It's too bad. But the Tunguska event was similar enough to a number of other witnessed events that we have a pretty good idea of why it happened and what the impactor was.

@MeteoriteGallery

From Tunguska, nothing larger than ~sub-mm spherules has been found. It's difficult to say whether or not any larger fragments reached the ground because some meteorite types like carbonaceous chondrites would probably turn to ~mud after a few years in that climate. Even if they fell, the first expedition arrived years after the event and there wouldn't have been anything to find. In general, hunting in dense vegetation for stones that had fallen years prior would be extremely difficult. Most stones from witnessed meteorite falls are recovered within a few days or weeks of the fall, because impact holes quickly disappear and fresh growth and dead leaves will hide anything small on the surface within weeks to months. There could still be stones out there, but it's also possible that none reached the ground, or that they were something like a CI chondrite, which turned to mud within a few weeks or months. We don't know for certain.
