Fireball streaks across the morning sky

Fireball streaks across the morning sky

A fireball cruised over our city this morning, surprising early-morning commuters.
Our 660News line has been inundated with callers saying they saw a fireball streak across the sky.
Callers tell us the bright green, yellow and blue streak beamed across the heavens, and then broke apart into six or seven pieces, before disappearing.

The fireball apparently streaked from east to west across, and lit up the sky for about ten seconds.

The last time a meteorite lit up the sky was in November, when a massive space rock came through our atmosphere. Researchers later found fragments of the debris in northwestern Saskatchewan.

East Coast Event NOT A ROCKET 31MAR09

NOT A ROCKET
by Dr. Tony Phillips
SpaceWeather.com 31MAR09

News reports that a Russian rocket fell over the US mid-Atlantic coast on Sunday evening, March 29th, are probably incorrect. A spent Russian rocket booster did reenter Earth's atmosphere on March 29th, but apparently not over the USA. According to data published by US Strategic Command, the reentry occurred near Taiwan (24° N, 125° E) at 11:57 p.m. EDT. So what were those lights in the sky over Maryland and Virginia two hours earlier? Eyewitness accounts of the Atlantic Coast fireball are consistent with a meteoritic bolide--a random asteroid hitting Earth's atmosphere and exploding in flight.

Streaking lights, explosions reported Dorchester County, Md., to the Virginia/North Carolina border 29MAR09

By Patrick Wilson
The Virginian-Pilot© March 30, 2009

Were they meteors? A comet? UFOs?
People from Maryland to Hampton Roads heard loud explosions and saw brilliant, streaking lights in the sky Sunday night.
There was no immediate explanation, the National Weather Service office in Wakefield said. The Virginia Beach 911 center had numerous calls waiting just before 10 p.m., a supervisor said.
The Weather Service said reports were made from Dorchester County, Md., to the Virginia/North Carolina border. People said they saw a streak in the sky and heard an explosion.
“It was orange, like a fireball,” said Steve Wagner, who lives in the Great Bridge area of Chesapeake and said what he saw was too close to be a shooting star. Wagner was outside cooking with family when he saw the streak. He said he went inside when his daughter called, then heard an explosion that sounded like thunder.
Chris Wamsley, a meteorologist with the National Weather Service’s Wakefield office, said there could be various causes of the explosions and lights. A team of people is looking into what happened, he said.
Lindsey Hosek of the Great Neck area of Virginia Beach was jogging along the water with her dog when the sky lit up, she said.
“The bright light at first terrified me because I thought somebody was shining a light on me, and then I saw it, and I was in complete awe because it was so beautiful,” she said.
Then she saw something that looked like a comet moving low toward the ground; it was blue in front followed by orange and appeared to be the shape and size of a refrigerator.
“It was just so low. It was like where a bird should be,” she said. “It was definitely heading downward.”
She was on the phone with a friend a minute later when she heard an explosion.
Kenneth Martin of Chesapeake’s South Norfolk neighborhood said he saw what appeared to be lightning, then the sky turned blue.
Then, he said, a white ball of fire shot close to the ground and appeared to burn out. He said he’s sure it was a meteor.
“It was so vivid in the sky, blinking,” he said. “It was the strangest thing I’ve ever seen.”
No damage was reported, the Weather Service said.

On Feb. 15 in Austin, Texas, runners struggled through the streets, midmarathon. A news cameraman covering the race happened to catch a fireball streaking through the sky.
The first news reports said a plane had crashed. A helicopter was dispatched to the site.
But there was no plane.
In Hillsboro, Rob Wesel thought he knew exactly what had happened: A meteoroid had streaked to Earth, scattering fragments -- or meteorites -- over Texas farmland.

Time to Solidify an Ocean of Magma -Lunar Study 29MAR09

Time to Solidify an Ocean of Magma
25MAR09
--- A small mineral grain places limits on how long it took the lunar magma ocean to solidify.

Written by G. Jeffrey Taylor
Hawai‘i Institute of Geophysics and Planetology
Cosmochemists are reasonably sure that a global ocean of magma surrounded the Moon when it formed. This was a monumentally important event in lunar history, forming the primary feldspar-rich crust of the lunar highlands and setting the stage for subsequent melting inside the Moon to make additional crustal rocks. Numerous questions remain about the complex array of processes that could have operated in such a huge amount of magma, and about how long it took to solidify the magma ocean. Alex Nemchin and colleagues at Curtin University of Technology (Australia), Westfäilische Wilhelms-Universität (Münster, Germany), and the Johnson Space Center (Houston, Texas, USA) dated a half-millimeter grain of the mineral zircon (ZrSiO4) in an impact melt breccia from the Apollo 17 landing site. They used an ion microprobe to measure the concentrations of lead and uranium isotopes in the crystal, finding that one portion of the grain recorded an age of 4.417 ± 0.006 billion years. Because zircon does not crystallize until more than 95% of the magma ocean has crystallized, this age effectively marks the end of magma ocean crystallization. Magma ocean cooling and crystallization began soon after the Moon-forming giant impact. Other isotopic studies show that this monumental event occurred 4.517 billion years ago. Thus, the difference between the two ages means that the magma ocean took 100 million years to solidify.

Moments ago... as I was observing the Orion Nebula through my SN8/LXD (8") Shmidt-Neutonian, I saw a white flash that lit up the aperature of the scope. Upon looking up toward Orion I saw a persistant trail lasting about 2 seconds and quite long (~7 degrees.). I summoned wife to watch telescope while checking the Sentinel camera to see if it got it too. It did! A SLOW and nice Bolide with a double explosion and apparent fragmentation products clearly evident however small they are. The Fireball was heading toward the Nebula but did not quite reach it from my location 35 miles North of Sacramento.

2008 TC3, Almahata Sitta meteorite came from F-class asteroid 26MAR09

http://www.sciam.com/article.cfm?id=asteroid-meteorite-sudan-fireball

Rock Science: First Meteorites Recovered on Earth from an Asteroid Tracked in Space Fragments in the Sudanese desert make up an "asteroid trifecta":
discovery, prediction and recovery By John Matson Scientific American March 25, 2009

Last October, asteroid monitors at the Catalina Sky Survey at the University of Arizona in Tucson picked up a small object on an immediate collision course with Earth. The asteroid was too small to present a real threat - just a few meters across, it stood little chance of penetrating the atmosphere intact. Indeed, it exploded in astratospheric fireball over northern Sudan less than 24 hours later - anevent witnessed by people on the ground as well as the pilots of a KLM airliner- conforming well to astronomer's predictions for its trajectory. But the asteroid, dubbed 2008 TC3, was nonetheless a momentous discovery: Among the countless small objects that strike Earth's atmosphere every year, none had ever been detected and tracked before it impacted. Now the Sudan bolide has yielded yet another first:

Researchers report in Nature today
<http://www.nature.com/nature/journal/v458/n7237/full/nature07920.html>that they have recovered 47 meteorites from the object in the Nubian Desert. And lead author Peter Jenniskens, a meteor astronomer at the SETI Institute in Mountain View, Calif., says that another search completed earlier this month, after the paper was submitted, has upped the meteorite count to about 280.
Astronomer Donald Yeomans, manager of NASA's Near-Earth Object Programoffice <http://neo.jpl.nasa.gov/> at the Jet Propulsion Laboratory inPasadena, Calif., calls 2008 TC3 "a perfect asteroid trifecta,"referring to "pre-impact discovery, successful impact prediction, and successful sample return." (Yeomans did not contribute to the recovery research, but his office played a leading role in tracking the asteroid's entry <http://www.cfa.harvard.edu/mpec/K08/K08T50.html>.)

The find allows astronomers to connect the chemical composition of the meteorite to its orbit and reflectance in the sky during tracking. "The holy grail of asteroid science is to uniquely link a specific meteorite and its detailed composition to a specific asteroid type," Yeomans says."And that has now been done without an expensive sample-return mission. "This object, which the study's authors call Almahata Sitta (Arabic for Station Six, a train station in the desert where eyewitnesses saw the fireball and that served as the researchers' base camp), appears to belong to a rare class of bodies called F-class asteroids, which constitute just 1.3 percent of all asteroids. Chemically speaking, Almahata Sitta is a meteorite whose specific composition is unique among meteorite collections. It is a fragile, porous ureilite (a relatively rare kind of olivine- and pyroxene-bearing meteorite)containing graphite and nanodiamonds, among other materials. Its fragility, Jenniskens says, helps explain why it broke apart so high in the atmosphere. With the benefit of the object's rarity as an F-class body and its orbit, tracked backward through time, the researchers established a possible link to a larger F-class asteroid, the 1.6-mile-(2.6-kilometer-) diameter 1998 KU2, which may have originated from the same parent body as Almahata Sitta."The orbit of the asteroid, by just tracking it for 20 hours, is 10,000times better than anything you can get from just observing a fireball Jenniskens says. "What's neat about this is that the big asteroid allows you to extend back in time the evolutionary history." He notes that scientists might be able to pinpoint the specific region of the asteroid belt that 2008 TC3 came from with more F-class asteroids from the same parent body. Even the brief amount of time 2008 TC3 was tracked provided an excellent lead on where to look- and the desert surface provided an ideal surface for turning up the dark fragments. "The entry trajectory was very precisely known," Jenniskens says. The first samples were found in early December by a 45-person search team from the University of Khartoum. (Three scientists from that university and one from the University of Juba in Sudan are among the co-authors of the study.) "We had many eyes and hands," Jenniskens says, trying "to find these."

“Sirente crater”, Italy impact origin disputed 26MAR09

An article in journal of Geophysical Research disputes the origin of the what has been called the “Sirente crater”.The paper discussing this theory is:
Speranza, F., I. Nicolosi, N. Ricchetti, G. Etiope, P. Rochette, L. Sagnotti, R. De Ritis, and M. Chiappini (2009), The “Sirente crater field,” Italy, revisited. Journal of Geophysical Research. vol. 114, B03103, doi:10.1029/2008JB005759
http://www.agu.org/pubs/crossref/2009/2008JB005759.shtml

They concluded:
“Our data show that the Sirente crater and the minor depressions are simply the results of human activity and karstic processes, respectively.”

Asteroid Impact Helps Trace Meteorite Origins

The car-sized asteroid that exploded above the Nubian Desert last October was small compared to the dinosaur-killing, civilization-ending objects that still orbit the sun. But that didn't stop it from having a huge impact among scientists. This was the first instance of an asteroid spotted in space before falling to Earth. Researchers rushed to collect the resulting meteorite debris, and a new paper in Nature reports on this first-ever opportunity to calibrate telescopic observations of a known asteroid with laboratory analyses of its fragments."Any number of meteorites have been observed as fireballs and smoking meteor trails as they come through the atmosphere," says Douglas Rumble of the Carnegie Institution's Geophysical Laboratory, a co-author of the paper."It's been happening for years. But to actually see this object before it gets to the Earth's atmosphere and then to follow it in -- that's the unique thing."The chemical compositions of asteroids can be studied from Earth by analyzing the spectra of sunlight reflected from their surfaces. This provides enough information to divide asteroids into broad categories, butdoes not yield detailed information on their compositions. On the otherhand, meteorites recovered on Earth can be analyzed directly for chemical composition, but researchers generally have no direct information on what type of asteroid they came from.The asteroid, known as 2008 TC3, was first sighted October 6, 2008, by telescopes of the automated Catalina Sky Survey near Tucson Arizona. Numerous observatories followed its trajectory and took spectrographic measurements before it disappeared into the Earth's shadow the following day. A recovery team led by Peter Jenniskens of the SETI Institute in California and Muawia Shaddad of the University of Khartoum then searched for meteorites along the projected approach path in northern Sudan. They recovered 47 fragments, one of which was selected for preliminary analysisby laboratories, including the Carnegie Institution's Geophysical Laboratory."This asteroid was made of a particularly fragile material that caused it to explode at a high 37 kilometer altitude, before it was significantly slowed down, so that the few surviving fragments scattered over a large area,"explains Jenniskens, the lead author of the Nature paper. "The recovered meteorites were unlike anything in our meteorite collections up to that point."Carnegie's Andrew Steele studied the meteorite's carbon content, which showed signs that at some point in its past the meteorite had been subjected to very high temperatures. "Without a doubt, of all the meteorites that we've ever studied, the carbon in this one has been cooked to the greatest extent," says Steele. "Very cooked, graphite-like carbon is the main constituent of the carbon in this meteorite." Another form of carbon Steele found in the meteorite, nanodiamonds, may give clues as to whether the heating was caused by impacts on the parent asteroid, or by some other process. Oxygen isotopes in the meteorite give other information about its parent body. Each source of meteorites in the solar system, including planets such as Mars, has a distinctive signature of the three isotopes 16O, 17O, and18O. This signature can be recognized even when other variables, such as chemical composition or rock type, differ. "Oxygen isotopes represent the single most decisive measurement in determining the parental or family groupings of meteorites," says Rumble who performed the analysis. According to Rumble's analysis, 2008 TC3 falls into a category of very rare meteorites called ureilites, all of which may have originally come from the same parent body. "Where that is, we don't know," says Rumble. But because astronomers took spectral measurements of 2008 TC3 before it hit the Earth,and can compare those measurements with the laboratory analyses, scientists will be better able to recognize ureilite asteroids in space. One known asteroid with a similar spectrum, the 2.6 kilometer-sized asteroid 1998 KU2, has already been identified by researchers as a possible source for 2008 TC3. Rumble's work was funded by NASA Cosmochemistry grant NNX07AI48G. Steele was supported by NASA's Sample Return Laboratory Instruments and Data Analysis Program (SRLIDAP) , NASA's Astrobiology Science and Technology for Exploring Planets (ASTEP) program , and the NASA Astrobiology Institute (NAI).

FOR IMMEDIATE RELEASE: March 25, 2009

We saw it coming:

Asteroid monitored from outer space to ground impact

Sandians Mark Boslough and Dick Spalding watch it in real time

ALBUQUERQUE, N.M. -- Reports by scientists of meteorites striking Earth in the past have resembled police reports of so many muggings -- the offenders came out of nowhere and then disappeared into the crowd, making it difficultto get more than very basic facts.Now an international research team has been able to identify an asteroid inspace before it entered Earth's atmosphere, enabling computers to determineits area of origin in the solar system as well as predict the arrival timeand location on Earth of its shattered surviving parts."I would say that this work demonstrates, for the first time, the ability ofastronomers to discover and predict the impact of a space object," saysSandia National Laboratories researcher Mark Boslough, a member of theresearch team.Perhaps more importantly, the event tested the ability of society to respond very quickly to a predicted impact, says Boslough. "In this case, it was never a threat, so the response was scientific. Had it been deemed a threat-- a larger asteroid that would explode over a populated area -- an alert could have been issued in time that could potentially save lives by evacuating the danger zone or instructing people to take cover. "The profusion of information in this case also helps meteoriticists learn the orbits of parent bodies that yield various types of meteorites.Such knowledge could help future space missions explore or even mine the asteroids in Earth-crossing orbits, Boslough says.The four-meter-diameter asteroid, called 2008 TC3, was initially sighted by the automated Catalina Sky Survey telescope at Mount Lemmon, Ariz., on Oct.6. Numerous observatories, alerted to the invader, then imaged the object. Computations correctly predicted impact would occur 19 hours after discovery in the Nubian Desert of northern Sudan. According to NASA's Near Earth Object program, "A spectacular fireball litup the predawn sky above Northern Sudan on October 7, 2008."A wide variety of analyses were performed while the asteroid was en route and after its surviving pieces were located by meteorite hunters in an intense search.

Researchers, listed in the paper describing this work in the March 26 issueof the journal Nature, range from the SETI Institute, the University of Khartoum, Juba University (Sudan), Sandia, Caltech, NASA Johnson Space Center and NASA Ames, to other universities in the U.S., Canada, Ireland,England, Czech Republic and the Netherlands. Sandia researcher Dick Spalding interpreted recorded data about the atmospheric fireball, and Boslough estimated the aerodynamic pressure and strength of the asteroid based on the estimated burst altitude of 36 kilometers. Searchers have recovered 47 meteorites so far -- offshoots from the disintegrating asteroid, mostly immolated by its encounter with atmospheric friction -- with a total mass of 3.95 kilograms.The analyzed material showed carbon-rich materials not yet represented in meteorite collections, indicating that fragile materials still unknown may account for some asteroid classes. Such meteorites are less likely to survive due to destruction upon entry and weathering once they land on Earth's surface."Chunks of iron and hard rock last longer and are easier to find than clumps of soft carbonaceous materials," says Boslough."We knew that locating an incoming object while still in space could be done, but it had never actually been demonstrated until now," says Boslough."In this post-rational age where scientific explanations and computer models are often derided as 'only theories,' it is nice to have a demonstration like this."Sandia is a multiprogram laboratory operated by Sandia Corporation, a Lockheed Martin company, for the U.S. Department of Energy's National Nuclear Security Administration. With main facilities in Albuquerque, N.M.,and Livermore, Calif., Sandia has major R&D responsibilities in national security, energy and environmental technologies, and economic competitiveness.

Dr. Kennett gave a talk, which included a lot of research that is either being prepared for publication, been submitted for publication, and in press. Dr. Kennett made a very convincing case that something unique, extraordinary, and instantaneous occurred at the beginning of the Younger Dryas about 12,900 B. calender years ago and could be an event that was extraterrestrial in nature. His idea that it involved multiple, simultaneous Tunguska-like events occurring across the North American continent. He also, discussed and showed pictures of the research on the Greenland ice sheet, carried out by Paul Mayewski, and Andrei Kurbatov. Outcropping along the edge of the Greenland Ice Sheetis a well defined Younger Dryas bed, which consists of dark greydusty ice with clean, white Holocene ice above it and clean, white terminal Pleistocene ice below it. They found the nannodiamonds and other alleged impact indicators right at and only at the basal contact of the Younger Dryas ice layer. They found exactly what would be expected for an layer of meteoritic debris from Tunguska-like events.

This is a show that you do not want to miss.It is in the realm of possibility, that decade or so from now, Dr. West, Dr. Kennett, and other members the YDB Group will likely be known as the "Walter Alvarezes of the Quaternary.

I am now getting together with a couple of archaeologists to do some “prospecting” for nannodiamonds and microspherules.
