[meteorite-list] More historic falls
Mark, Liking the website, I always enjoy the histories and stories that historic meteorites have to offer to the meteorite collection community. These historic falls help mold and guide meteorites collecting and science the way it is today. Enjoy to see more from this website and other historic meteorite website. Long live history.

[meteorite-list] Fireball question / sonic boom
Hi List, It seems like there have been many fireball sightings in the past few months but no material being found on the ground, as in the recent Oklahoma event. I was wondering if the absence of a sonic boom has anything to do with it. Does a sonic boom or explosion have to be present for a major meteorite producing event? Could there still be a few meteorites on the ground with no sonic boom? With Buzzard Coulee, Mifflin, Ash Creek these events all produced meteorites and sonic booms were heard by the locals. Does anyone know if there were sonic booms associated with the Park Forest and Whetstone events? Thanks, Sonny __ Visit the Archives at http://www.meteoritecentral.com/mailing-list-archives.html Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list

The actual term commonly found in the scientific literature is potted butt. It refers to a small specimen embedded in some kind of supporting medium, usually epoxy, acrylic, or the like, prior to sample processing. These samples then may be sliced for thin section preparation or other purposes, or, for tiny samples, just ground down to expose the sample surface. If one wishes to do microscopic examination of the sample remaining in a potted butt, the surface (sample plus supporting medium) is commonly polished. This is what Cascadia is calling a polished butt.

Re: [meteorite-list] Smallest Complete Meteorite?
Of course, there is a continuum of meteorite sizes down through micrometeorites to dust, all of which have been collected on Earth. The smallest named meteorite found on Earth may be Yamato 8333, at 10 mg. There are perhaps a dozen more, all Antarctic, below 100 mg. In Rubin and Grossman (2010), we assert that micrometeorites are meteorites, and we set the lower size limit for micrometeorites at 10 micrometers. Such a particle, if chondritic, would weigh a few nanograms. So I would therefore assert that the smallest collected meteorite weighs ~1 ng. The word complete is the difficult part of this question. I don't know what it means.

Re: [meteorite-list] Fireball question / sonic boom

I was wondering if the absence of a sonic boom has anything to do with it. Does a sonic boom or explosion have to be present for a major meteorite producing event? Could there still be a few meteorites on the ground with no sonic boom? With Buzzard Coulee, Mifflin, Ash Creek these events all produced meteorites and sonic booms were heard by the locals. Does anyone know if there were sonic booms associated with the Park Forest and Whetstone events?

[meteorite-list] When is an Asteroid Not an Asteroid?
http://www.jpl.nasa.gov/news/news.cfm?release=2011-100 When is an Asteroid Not an Asteroid? Jet Propulsion Laboratory March 29, 2011 On March 29, 1807, German astronomer Heinrich Wilhelm Olbers spotted Vesta as a pinprick of light in the sky. Two hundred and four years later, as NASA's Dawn spacecraft prepares to begin orbiting this intriguing world, scientists now know how special this world is, even if there has been some debate on how to classify it. Vesta is most commonly called an asteroid because it lies in the orbiting rubble patch known as the main asteroid belt between Mars and Jupiter. But the vast majority of objects in the main belt are lightweights, 100-kilometers-wide (about 60-miles wide) or smaller, compared with Vesta, which is about 530 kilometers (330 miles) across on average. In fact, numerous bits of Vesta ejected by collisions with other objects have been identified in the main belt. I don't think Vesta should be called an asteroid, said Tom McCord, a Dawn co-investigator based at the Bear Fight Institute, Winthrop, Wash. Not only is Vesta so much larger, but it's an evolved object, unlike most things we call asteroids. The layered structure of Vesta (core, mantle and crust) is the key trait that makes Vesta more like planets such as Earth, Venus and Mars than the other asteroids, McCord said. Like the planets, Vesta had sufficient radioactive material inside when it coalesced, releasing heat that melted rock and enabled lighter layers to float to the outside. Scientists call this process differentiation. McCord and colleagues were the first to discover that Vesta was likely differentiated when special detectors on their telescopes in 1972 picked up the signature of basalt. That meant that the body had to have melted at one time. Officially, Vesta is a minor planet -- a body that orbits the sun but is not a proper planet or comet. But there are more than 540,000 minor planets in our solar system, so the label doesn't give Vesta much distinction. Dwarf planets -- which include Dawn's second destination, Ceres -- are another category, but Vesta doesn't qualify as one of those. For one thing, Vesta isn't quite large enough. Dawn scientists prefer to think of Vesta as a protoplanet because it is a dense, layered body that orbits the sun and began in the same fashion as Mercury, Venus, Earth and Mars, but somehow never fully developed. In the swinging early history of the solar system, objects became planets by merging with other Vesta-sized objects. But Vesta never found a partner during the big dance, and the critical time passed. It may have had to do with the nearby presence of Jupiter, the neighborhood's gravitational superpower, disturbing the orbits of objects and hogging the dance partners. Other space rocks have collided with Vesta and knocked off bits of it. Those became debris in the asteroid belt known as Vestoids, and even hundreds of meteorites that have ended up on Earth. But Vesta never collided with something of sufficient size to disrupt it, and it remained intact. As a result, Vesta is a time capsule from that earlier era. This gritty little protoplanet has survived bombardment in the asteroid belt for over 4.5 billion years, making its surface possibly the oldest planetary surface in the solar system, said Christopher Russell, Dawn's principal investigator, based at UCLA. Studying Vesta will enable us to write a much better history of the solar system's turbulent youth. Dawn's scientists and engineers have designed a master plan to investigate these special features of Vesta. When Dawn arrives at Vesta in July, the south pole will be in full sunlight, giving scientists a clear view of a huge crater at the south pole. That crater may reveal the layer cake of materials inside Vesta that will tell us how the body evolved after formation. The orbit design allows Dawn to map new terrain as the seasons progress over its 12-month visit. The spacecraft will make many measurements, including high-resolution data on surface composition, topography and texture. The spacecraft will also measure the tug of Vesta's gravity to learn more about its internal structure. Dawn's ion thrusters are gently carrying us toward Vesta, and the spacecraft is getting ready for its big year of exploration, said Marc Rayman, Dawn's chief engineer at NASA's Jet Propulsion Laboratory, Pasadena, Calif. We have designed our mission to get the most out of this opportunity to reveal the exciting secrets of this uncharted, exotic world. The Dawn mission to Vesta and Ceres is managed by the Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, for NASA's Science Mission Directorate, Washington. The Dawn mission is part of the Discovery Program managed by NASA's Marshall Space Flight Center in Huntsville, Ala. UCLA is responsible for overall Dawn mission science. Orbital Sciences Corporation of Dulles, Va., designed and built the Dawn spacecraft. The

Re: [meteorite-list] Fireball question / sonic boom
Curious... I know there are many variables involved, and it probably varies with the conditions under which each event occurs, but I've read that some people have heard sonic booms (as low boom/rumbles) up to 50 miles away or more. Couldn't one figure out that distance by calculating altitude of any given bolide and air pressure/temp during the time of the event, (since it affects the sound waves at different elevations) to determine how far from the epicenter someone could here the sonic boom? I'm seriously curious about this.

Dear List, I vaguely remember seeing a schematic somewhere many years ago of how a sample of the Tucson Ring was sectioned into pieces. Does anyone remember this or know where I can find it? Also, I am interested in knowing where, exactly, samples were actually removed from the ring. I have an old woodcut from 1855 that shows the ring in its original state and I notice there is a nodular mass inside the ring that is not present on the current mass. Is this removed portion the source of all the small specimens in collections today?

[meteorite-list] Sonic Boom
Hi All, I had a chance to talk to Skip Wilson about the Portales Fall. The occupants of two of the nearby residences (about a half mile apart) sitting directly under the main break up did not hear anything. One of the residents happened to be working outside when the meteorite broke apart. Interestingly enough the Portales residents who were situated directly behind and in front of the break up heard two distinct sonic booms.

Re: [meteorite-list] Sonic Boom
Hello Sonny and Listmembers, Interesting. Perhaps the sound waves travel around the epicenter (anything located directly beneath) as they move towards the ground. I imagine circular rings moving expanding in an outward direction as they travel to the Earths surface. The higher the altitude of breakup, the larger the rings will be when they touch down... and the further away one must be from the center to actually hear the sonic booms. This is just a guess. Anyone with more knowledge care to elaborate on this hypothesis?

Re: [meteorite-list] Fireball question / sonic boom
Something to consider... If all events with sonic booms generate meteorites, then there are meteorites on the ground in Louisiana/Mississippi from the big fireball there a couple of months back.

Re: [meteorite-list] Fireball question / sonic boom
I think most large fireballs do not produce meteorites. Most meteorites are the product of rather ordinary meteors, which survive because they are slow and shallow and slow down while still very high, don't fragment, and produce single individuals. Of course, the vast majority of these are never found, and those that are have no associated fireball. When there are big fireballs- the sort that get meteorite hunters salivating- the situation is different. Most big fireballs probably don't produce meteorites. Those that do, however, do so because they start off with enough mass that they can afford to lose 95% of it and still have something get low enough to hit dense air at a low enough speed to avoid complete destruction. That height is below about 30 km, which happens to be about the height where sonic booms can be produced and reach the ground. So the presence of a sonic boom with a fireball is a useful indicator that meteorites might be produced. The absence of one, however, probably shouldn't be taken as an indicator that they were not, since a meteor can still end (without complete ablation) high enough that no sonic boom will reach the ground.

I was wondering if the absence of a sonic boom has anything to do with it. Does a sonic boom or explosion have to be present for a major meteorite producing event? Could there still be a few meteorites on the ground with no sonic boom? With Buzzard Coulee, Mifflin, Ash Creek these events all produced meteorites and sonic booms were heard by the locals. Does anyone know if there were sonic booms associated with the Park Forest and Whetstone events?

Re: [meteorite-list] Fireball question / sonic boom
The vast majority of meteorites retard while they are still far too high for sonic booms to reach the ground. The big, impressive fireballs that are more massive and reach lower heights are the exceptions. The meteoroids that slow down while still high are more likely to produce single meteorites; those that have enough mass to reach low altitudes still traveling at high speed tend to fragment and produce strewn fields.

Re: [meteorite-list] Fireball question / sonic boom
Ablation ceases at 3-4 km/s (about Mach 10), and this is about where the meteoroid becomes invisible. For a typical meteorite, it will rapidly lose this remaining velocity and enter nearly vertical dark flight.
