Exploring the Pingualuit Impact Crater
by Charles O’Dale, Ottawa Centre (codale0806@rogers.com)
Introduction
The Pingualuit Impact Crater, located in northern Quebec at N 61° 16´ W 73° 40´, was the first structure in Canada for which an impact origin was proposed. The structure is classified as a simple crater, 2.8 km in diameter and 400 m deep. It is slightly larger than the smallest crater on the Moon that is observable from our planet (Meen 1951). The inner slopeof the 3.4-km-diameter rim averages 30° and the outer slope averages 10°. The rim extends to a diameter of ~4.6 km and continues gradually outward to merge with the surrounding terrain at ~6.6 km. The peak of the rim is ~160 m above the inner lake level and 120 - 150 m above the regional terrain. The lake within the crater, with a depth of over 250 m, is one ofthe deepest in North America. It is also one of the clearest in the world with a transparency of over 35 m. Dating using the isotope ratio 40Ar-39Ar (Grieve 2006) gives the impact structurean age of 1.4 ± 0.1 Ma. The Pingualuit Impact Crater was formerly named New Quebec Crater and, previous to that, Chubb Crater.

Meteorite hunter donates rare find

By KGW Staff
PORTLAND -- A meteorite hunter from Portland is donating part of a recent find to Portland State University.
Video: Fireball during Texas marathon
Meteor fireball in sky
Meteorite donated to PSU
You may have seen the video of the fireball captured during a marathon last month near Austin, Texas.
When Patrick Thompson heard about it, he decided to spend eight days looking for parts of the meteor and he was successful. After searching on foot an average of 25 miles a day, he ended up finding 14 fragments of the meteorite.
For Thompson, it’s a true treasure.
“There's something about it, something about putting your hands on a rock and being the first person to touch it,” he said. “It came from space. These things are floating around up there, every time you see a shooting star, you're kind of reminded of the fact that these things are coming to earth, bombarding us all the time.”
Scientists said because Thompson’s latest meteorite finds are so fresh, the rocks are especially valuable.
Thompson said he plans to sell some of the rocks after donating at least one of them to PSU.

Student`s Science Fair Project on Earth Microbes 6MAR09
Students show off science projects
by Garrett Andrews
Herald Staff Writer
Article Last Updated; Friday, March 06, 2009
Speaking only slightly louder than the buzz of several hundred other student-scientists inside the reverberating concrete walls of the La Plata County Fairgrounds, Pagosa Springs eighth-grader Kendra Schlom explained her answer to the determining question of human existence: How did life on Earth originate?
She was discussing her entry in the San Juan Basin Regional Science Fair, a project that supports the idea that a meteorite could have transported early microbes to Earth.
In her project, titled "Finding the Origin," Kendra located the highest survivable temperatures for several primitive microbes and tested to see if these microbes could survive the temperatures a meteorite sustains when entering the Earth's atmosphere and crashing into the surface. She used basalt tiles to simulate chondrite meteorites.
Kendra and her father, a mechanic at Wolf Creek Ski Area, took an acetylene torch to samples of varying thicknesses, to analyze the time it takes the heat to completely penetrate the samples.
"From this information, I think that microbes could survive, because the temperature never exceeded the limit of what they could survive in," she said. "I believe that even if we went into lower thicknesses, they could survive, as long as the meteor is a quarter inch or thicker."
If she's right, then it's theoretically possible that these lone microbes ignited the evolutionary process that produced all of life as we know it.
Kendra, who hopes to study quantum physics at the Massachusetts Institute of Technology after high school, was one of 209 entries in this year's fair. About 20 winners will travel to the state science fair in Denver later this month.
Fair coordinator Jeff Hatfield said that as scores in science, technology and math continue to slide, events like science fairs become more important.
"CSAP scores and other assessment data show that we really need to ramp this up a bit. The fair is when you can actually get kids to dedicate their time to an actual science project. They're doing all the learning on their own.
"The bottom line is that we want these kids to be strongly rooted in science and technology," he said.
Not all the other projects had such divine implications as Kendra's, but most reflected hours of original study.
Bayfield eighth-grader Denvir Clarke placed bacteria in petri dishes and studied over time the effects of various germ-killing household cleaning products.
"I found that my hypothesis was wrong," she said near the end of a run-through of her presentation.
"Antibacterial soap is less effective at killing bacteria than regular soap."
Standing near a prototype of his invention was Kolton Miller, an eighth-grader at Mancos Middle School. He rushed through the features of the Bear-icade self-opening bear-proof trash can with the panache of a salesman, eagerly maintaining eye contact and gesturing with his hands, even as he went on bear-related tangents.
"I'm aware there's already a bear-proof trash can on the market today. The difference is, my trash can is more convenient," Kolton said.
With the Bear-icade, there's no more manual locking and unlocking. The device automatically locks after the lid is lifted and closed, and is disengaged by the extending arm of a garbage truck. Best of all, Kolton said, area bears stay safe and out of trouble.
Upstairs, the four judges for the earth sciences category pored over the merits of the nine projects assigned to their section. Consulting geologist Mary Gillam, retired geophysicist James Albright, consulting geotechnical engineer Barb McCall and school psychologist Patrick Callahan were unanimous in supporting Kendra for first place in her division.
Her idea provoked discussion at a table of professionals.
"It was an unusual approach to an ambitious topic," said Gillam.
Said McCall: "It could be the answer to life's biggest question. Right here in Durango."
The contestants each went through two rounds of judging and some were called back. The judges put Kendra on the spot during her presentation, asking about the effects of kinetic energy on the microbes, and she took their questions in stride and admitted when she didn't know.
All of the entries were good, the judges said.
"She was just far more expansive," said Albright.

Western astronomers on hunt for meteor
By Communications Staff Friday, March 7, 2008
Astronomers from The University of Western Ontario have captured rare video of a meteor falling to Earth, and are hoping to enlist the help of local residents in recovering one or more possible meteorites that may have crashed in the Parry Sound area.

The Physics and Astronomy Department at Western has a network of all-sky cameras in Southern Ontario that scan the sky monitoring for meteors. Associate Professor Peter Brown, who specializes in the study of meteors and meteorites, says that Wednesday evening (March 5) at 10:59 p.m. EST these cameras captured video of a large fireball and the department has also received a number of calls and emails from people who actually saw the light. Brown along with Wayne Edwards, a post doctorate student, are now working to get the word out among interested people who may be willing to see if they can spot any fallen meteorites. “Most meteoroids burn up by the time they hit an altitude of 60 or 70 kilometres from Earth," says Edwards. “We tracked this one to an altitude of about 24 kilometres so we are pretty sure there are at least one, and possibly many meteorites, that made it to the ground." Edwards says the lab can narrow the ground location where the meteorite would have fallen, to about 12 square kilometres and have created a map that may assist in locating the meteorite. The rock, or rocks, would probably weigh a kilogram or slightly more. “We would love to find a recovered meteorite on this one, because we have the video and we have the data and by putting that together with the meteorite, there is a lot to be learned." Wayne Edwards is available for interviews and/or to report finds at 519-850-2385. He can also be reached via email at wedwards@uwo.ca If you would like to receive a 14-mb video file of the meteor in avi format, maps or an image, please reply to this email address.
Reply Comment by Mark Langenfeld:
While I have heard nothing further, the linked maps suggest whatever survived may have splashed into Georgian Bay.
Reply Comment by Patrick Herrmann:
Nothing had been recovered from that fall. The stones fell too far out in Georgian Bay, and the ice was too thin to go by snowmobile. Point-au-Baril is what they ended up calling the potential strewn field.I was trying to get a helicopter lined up to go and look for some stones, but then, about a week or so after the fireball, there was another snowstorm, and that was it.

Tamarind the Australian dog proves Martian life 3MAR09
Australian dog proves Martian life
A dog trained to sniff out sewage-scented meteorites may have found evidence that life once existed on Mars, a discovery that could have saved NASA the expense of sending probes.
The Dingo-Kelpie mongrel picked out the unpleasant aroma of bacteria in mud from Queensland bacteria that matched fossils of primitive organisms in Martian rock that plunged into Antarctica 13,000 years ago.
Known as Tamarind to biophysicist owner Tony Taylor, the Australian dog could have saved NASA the bother of sending probes to the red planet - if only it had sniffed around filth in Moreton Bay sooner.
And NASA scientists who examined the potato-sized meteorite discovery, called ALH84001, agree this may well be proof that life really did exist on Mars.
Well-trained
Taylor said Tamarind came along on all his field trips, so training him to smell out sediments containing specific bacteria was quite easy. "It smells like sewage and she knows the word 'stinky'."
Based at the Australian Nuclear Science and Technology Organisation in Sydney, Taylor says he and colleague Professor John Barry have examined 82 different bacteria, retrieved from the area identified by the dog.
"When we say life, we're talking about bacteria, single cell primitive life forms, like we have here on Earth. It'd be underground, we'd have to drill down, so these little rovers that are crawling all over the surface would never find it" Tony Taylor,biophysicist.
They discovered they contained 11 characteristics also found in the Mars fossils, including a structure other scientists claimed could only be formed in intense heat.
"They were a perfect match, absolutely perfect. Eleven features out of 11," said Taylor, whose work, crediting Tamarind, was published on Thursday in the "Journal of Microscopy".
"These fossils are four billion years old. They pre-date the fossil record of life here on Earth."
Imaging technique
The bacteria-studying duo developed an imaging technique that allowed them to examine the bacteria at a much higher resolution - and they were delighted with the findings.
The scientists now believe the combined data warrant a manned mission to Mars to retrieve further samples.
"The results indicate very strongly that life was once there and... that life might still be there," Taylor said. "When we say life, we're talking about bacteria, single cell primitive life forms, like we have here on Earth."
"It'd be underground, we'd have to drill down, so these little rovers that are crawling all over the surface would never find it."
Two US-backed rovers are now exploring the red plant and transmitting unprecedented images of the barren landscape, but may achieve little else.

Tardigrades Space Travel on Meteorites Might Work 2MAR09
Eight-Legged Tardigrades Space Survivor Gives 'Panspermia' New Life 
Senior Science Writer

The revelation last week that tiny eight-legged animals survived exposure to the harsh environment of space on an Earth-orbiting mission is further support for the idea that simple life forms could travel between planets.
This idea, called panspermia, is not new. It holds that the seeds of life are everywhere, and that microbial life on Earth could have traveled here from Mars or even from another star system, and then evolved into the plethora of species seen today. In essence, we may all be Martians.
In various forms, the panspermia concept was discussed among scientists in the 1700s, again in the 1800s, and then notably when Sir Fed Hoyle and Chandra Wickramasinghe popularized it about 30 years ago. Mainstream scientists often dismissed the hypothesis, however, even into the 1990s.

ASTEROID FLYBY:
There's no danger of a collision, but newly-discovered asteroid 2009 DD45 will come close enough today when it flies by our planet 72,000 km (0.00048 AU) away. That's only twice the height of a geostationary communications satellite. The asteroid measures 30 to 40 meters across, similar in size to the Tunguska impactor of 1908. Closest approach occurs at approximately 1340 UT (5:40 am PST) on March 2nd. Experienced amateur astronomers may be able to photograph the space rock shining like an 11th magnitude star as it races through the constellations Hydra and Virgo. The timing favors observers in Hawaii, Australia, New Zealand, Japan and east Asia.

Tamdakht, Moroc Meteorite Hunting 27FEB09
Tamdakht, Moroc Meteorite Hunting by Philippe ThomasA meteorite fall occurred near Ouarzazate on December 20th, 2008, specifically around the villages of Tamdakht and Tiguert, located in the mountains northwest of the city. We decided to go there to gather more information on this fall and, eventually, to find some pieces. Departure for Morocco was on Wednesday, February 11th in the afternoon. The road is long, but we arrive in the south of the country on 12 at night, exhausted. Here, a few days of rest are necessary to recover the route and also to enjoy the sun that is so much lacking to us at home. Almost 30 ° C difference ... a pure happiness! We left for Ouarzazate on Monday, February 16th early in the morning. Our Moroccan friend accompanies us, he has toured a lot in the zone of the fall and knows many nomads who live in these mountains. We arrived at the entrance of Ouarzazate in early afternoon and we stop in the first Total gas station to find someone who is waiting for us to guide us to places where stones were found. Our two guides getting into our car and we started. The track which leads in mountains start at the end of a residential area. We see that it is a very used track, it is wide, flat (a real highway) and we can ride rather fast especially in 4x4!... the rest of the story at: http://www.meteoritica.com/tamdakht%20hunting%20trip.html

February 27, 2009
DALLAS - Police say a 6-pound chunk of metal that crashed through the roof of a Dallas home was part of a machine that was grinding up an unwanted tree nearby. Sgt. Gil Cerda says: "Mystery solved." So much for the theory it could have been a piece of debris from this month's collision of Russian and U.S. satellites.
Cerda says the metal chunk was a grinding tip of a mulching machine being used by a tree disposal service crew. No one was hurt when it went flying Tuesday. Senior Cpl. Janice Crowther said no charges will be filed against the business because it was an accident.
The satellite debris theory also came up when a fireball streaked across the Texas sky Feb. 15. That turned out to be a meteorite. It also surfaced last week when a piece of metal crashed through a New Jersey warehouse. That was another errant piece of a mulching machine.

DALLAS - Police say a 6-pound chunk of metal that crashed through the roof of a Dallas home was part of a machine that was grinding up an unwanted tree nearby. Sgt. Gil Cerda says: "Mystery solved." So much for the theory it could have been a piece of debris from this month's collision of Russian and U.S. satellites.
Cerda says the metal chunk was a grinding tip of a mulching machine being used by a tree disposal service crew. No one was hurt when it went flying Tuesday. Senior Cpl. Janice Crowther said no charges will be filed against the business because it was an accident.
The satellite debris theory also came up when a fireball streaked across the Texas sky Feb. 15. That turned out to be a meteorite. It also surfaced last week when a piece of metal crashed through a New Jersey warehouse. That was another errant piece of a mulching machine.

WEST — Meteorite hunters have descended in droves to the countryside surrounding this farming community, searching for the elusive pieces from a fireball that flared across the daytime sky over Central Texas and then broke apart.
But while the fireball and its accompanying sonic boom Feb. 15 were spectacular, West residents say they’ve got better things to do than hunt for the thousands of fragments that litter the land and might not even be on their property.
Spring planting is a focus for the farmers now. That meteorite hunters from across the country are asking to traipse across their fields looking for stones the size of a pecan or smaller at a crucial time for planting has more than a few farmers and ranchers perturbed. In some cases, people didn’t ask and trespassed.

"Fireball" sighting maybe a meteorite

Island residents are being urged by Maria Mitchell Association director of astronomy, Vladimir Strelnitski, to keep their eyes open for meteorites around Surfside and the south shore in the coming days following an unconfirmed sighting of a fireball blazing across the early-morning sky Friday, Feb. 20 at 4:30 a.m.
Terry Galschneider was up early watching television when she said a dramatic orange fireball "lit up the sky" for five seconds. She said the fireball was too large and bright to have been a shooting star or a helicopter. Her full description to Strelnitski left him to "not exclude that it fell in the ocean, but maybe even on land."The object's brightness suggests it would be relatively close to Galschneider, although its lack of sound made that even less possible to tell for certain. He said it was highly unlikely to have been debris from colliding satellites.The sighting was not confirmed by either Nantucket airport officials orby the police, and no other reports of fiery objects in the sky Friday in Massachusetts have been made to NASA, or to astronomy departments at Boston University, the University Massachusetts at Lowell, or the American Meteor Society. Other islanders who may have spotted the fireball are encouraged to contact Strelnitski at the Maria Mitchell Association at +1(508) 228-5273 .
Though unlikely, Strelnitski said discovering a meteorite - or part of one - on Nantucket would be unprecedented and could yield important information to scientists. People around Surfside especially are encouraged to look for unusual small craters with valleys on the surface with strange objects inside. Meteors can be a piece of metal, a greenish or grayish piece of stone, or a black piece of organic matter that resembles coal called carbonatious condrite, the rarest of all meteorites.

Another meteor impact coincides with large-scale volcanic eruptions
---Planet Earth online 23 February 2009
Scientists have long debated the cause of the dinosaurs' extinction about 65 million years ago. The remnants of a large volcanic eruption in the Faroe Islands. These eruptions can go on for millions of years. Around this time a giant meteorite struck the Gulf of Mexico. But the extinction also seems to coincide with massive and long-lasting volcanic eruptions in India known as the Deccan Traps. So which event was responsible? And are these phenomena linked?
New research now shows that this combination of meteorite impact andlarge-scale volcanic activity - known as flood basalt eruptions - is not unique. An international team of researchers looked at a 30-million-year-old meteorite crater in Belarus called Logoisk. They found that this too coincided with volcanic eruptions further south which covered Yemen and Ethiopia with basalt rock. These events are similar to those that occurred 65 million years ago, but on a much smaller scale. The scientists suggest such coincidences may be more common than previously thought. Dr Sarah Sherlock from the Open University and lead author of the paper, says, 'If you have a flood basalt then people wonder if there's also an impact. ''There will be, almost certainly,' she added. According to the paper, a meteorite will strike the Earth and leave a crater the size of Logoisk on average once every 1.5 million years. Flood volcanic eruptions occur over several million years, so a Logoisk-sized crater is likely to occur during each of the 16 identified periods of flood volcanism on Earth in the last 360 million years. However, researchers do not think there is a causal link between flood volcanism and meteorite impact.'There is simply no geological evidence to link the two,' says Sherlock. To determine the precise age of the Logoisk crater the researchers used argon dating. 'Argon dating is very versatile.' said Sherlock. 'It's the only technique that can be used to date both [impacts and flood volcanism].' Samples of material from the crater were gradually heated using an infrared laser, causing the release of argon gas. The ratio of two isotopes of argon released in the gas gives an accurate indication ofthe age of the sample. Using this technique, the researchers showed that the two events occurred simultaneously.
One question raised by the results was why the meteorite impact and flood volcanism 65 million years ago wiped out much of life on Earth, including the dinosaurs, but the similar events 30 million years ago did not. According to Sherlock, it was down to the size of the events.'These coincidences in Earth's history are not as rare as people think,but in order to actually do significant damage to the environment they have to be really, really big.' Sherlock added. Together, the 65-million-year-old Chicxulub crater in the Gulf of Mexico and volcanic eruptions that produced the Deccan Traps eruption 65 million years ago released 8000 gigatonnes (Gt) of sulfur dioxide, causing global environmental damage. By comparison the Logoisk and Afro-Arabian events released only 30Gt - insufficient to cause change on a global scale.
The research is published in the Journal of the Geological Society, London.

Comet Lulin visits inner Solar System 26FEB09

Comet Lulin visits inner Solar System
BY DR EMILY BALDWIN
ASTRONOMY NOW
23 February, 2009
On 24 February Comet Lulin will make its first visit to the inner Solar System, streaking past the Earth at a distance of 38 million miles, or 160 times further than the Moon. Comet Lulin, formally known as C/2007 N3, was discovered last year byastronomers at Taiwan's Lulin Observatory. Nicknamed the "green comet", Lulin's atmosphere contains poisonous cyanogen and diatomic carbongases. Researchers at the University of Leicester will be using NASA's Swift satellite to monitor the comet in X-ray, ultraviolet and optical light as it closes in on the Earth this week.
"The wonderful ease of scheduling of Swift and its joint UV and X-raycapability make Swift the observatory of choice for observations like these," says Dr Julian Osborne, leader of the Swift project at Leicester. The University of Leicester played a major role in developing Swift's X-Ray Telescope.

This image of Comet Lulin taken 28 Jan merges data acquired by Swift's Ultraviolet/Optical Telescope (blue and green) and X-Ray Telescope (red). At the time of the observation, the comet was 99.5 million milesfrom Earth and 115.3 million miles from the Sun. Image: Univ. of Leicester/NASA/Swift/Carter et al. Comets are thought to represent some of the most pristine ingredients ofthe Solar System. They are made up of dust, gas and ice, and as they approach the Sun, the frozen components sublime and stream out in tails. Swift observations of the comet on 28 January revealed that it is certainly active. "The UVOT data show that Lulin was shedding nearly 800 gallons of water each second," says team member Dennis Bodewits, a NASA Postdoctoral Fellow at the Goddard Space Flight Center in Greenbelt,which is enough to fill an Olympic-size swimming pool in less than 15 minutes. Although Swift can't see water directly, ultraviolet light from the Sunquickly breaks apart water molecules into hydrogen atoms and hydroxyl (OH) molecules, the latter of which Swift's Ultraviolet/OpticalTelescopes (UVOT) can detect. "This gives us a unique view into the types and quantities of gas a comet produces," Bodewits explains. The images taken so far reveal a hydroxyl cloud spanning a distance greater than the distance between Earth and the Moon, and a tail streaming off at an angle. Solar radiation pushes the icy grains awayfrom the comet, and as they gradually evaporate, they create a thin tail of hydroxyl molecules. Farther from the comet, even the hydroxyl molecule succumbs to solar ultraviolet radiation, breaking into its constituent oxygen and hydrogen atoms."The solar wind - a fast-moving stream of particles from the Sun -interacts with the comet's broader cloud of atoms," says Stefan Immler, also at Goddard. "This causes the solar wind to light up with X-rays,and that's what Swift's XRT sees." This interaction, called charge exchange, results in X-rays from most comets when they pass within about three times Earth's distance from the Sun. Because Lulin is so active and is losing a lot of gas, its X-ray emitting region extends in a largecloud far sunward of the comet. The team hope that the forthcoming observations of Lulin will reveal more on the comet's chemistry andenable scientists to build up a three-dimensional picture of the cometduring its maiden voyage through the Solar System.Comet Lulin will be visible to the naked eye, and for most locations inthe Northern Hemisphere will be easiest to spot after midnight when itis high in the sky. In small telescopes it will appear as a dim fuzzy"star" - brighter in the centre and more diffuse around the edges. It will fade from view by mid-March.
