Winter Olympic Gold Medalists to Get Bonus Meteorite Medal SaturdaySPACE.comBy Robert Z. Pearlman, collectSPACE.com 9 hours agoOlympic athletes placing gold on Saturday, Feb. 15, 2014 at the Sochi Winter Games will be conferred a bonus medal adorned with a fragment of the 2013 Chelyabinsk meteorite. What is better than winning gold at the Olympics? Winning gold at the Winter Olympic Games in Sochi, Russia on Saturday (Feb. 15) — because on that day, and that day alone, earning a gold medal also means being awarded a piece of a rock that fell from space.Saturday marks exactly one year since a small near-Earth asteroid entered the Earth's atmosphere over Russia and exploded over the Chelyabinsk Oblast (region). Regarded as the most widely witnessed asteroid strike in modern history, the Chelyabinsk meteor was also the largest recorded natural object to have fallen from space since 1908.The space rock broke into hundreds, if not thousands, of small fragments, which rained down over the area's snow-covered fields. Over the past year, many fragments of the Chelyabinsk meteorite have been recovered, with some of the pieces heading to labs for study, many landing on the collectors' market, others going to museums and a small set being placed aside for a special set of medallions.Ten of those medals will be presented to those who place gold at the Sochi 2014 Olympics on the anniversary of the Chelyabinsk meteor fall."We will hand out our medals to all the athletes who will win gold on that day [Feb. 15], because both the meteorite strike and the Olympic Games are global events," Alexei Betekhtin, culture minister for the Chelyabinsk region, in a statement.In total, 50 of the meteorite-adorned medallions have been minted. In addition to the those that will be awarded to the Olympic committees of those nations whose athletes win gold medals Saturday, one is being given to the regional Chelyabinsk museum, another will stay in Sochi and the remainder will be offered to private collections.The medallions, which were crafted out of gold and silver, feature a design that was inspired by the footage of the meteor's fall as captured by car-mounted dash cams. The videos from that day quickly went viral, shared across the planet by social media.The meteorite pieces are affixed in a small indentation at the center of the medals.The meteorite medals are not replacing the Olympic gold medals awarded to athletes on Saturday, contrary to some media reports. The Chelyabinsk medals will be presented to the athletes separately and not as part of the traditional podium ceremony.The 10 meteorite-embedded awards will be bestowed to the gold medal athletes competing in speedskating (men's 1500), short-track speedskating (women's 1000 and men's 1500), cross-country skiing (women's relay), ski jumping (men's K-125), Alpine skiing (women's super giant slalom) and skeleton (men's) events.Today, small fragments (2 to 3 grams) of the Chelyabinsk meteorite sell for $50 to $75. Larger fragments (between 5 and 10 grams) typically sell for $200 and above.The shock wave from the meteor damaged thousands of buildings in the Chelyabinsk Oblast, resulting in more than 1,500 people seeking medical help. Injuries ranged from cuts due to shattered glass windows, eye pain due to the brightness of the flash, ultraviolet burns and, in one of two serious injuries reported, a broken spine.The damage from the meteor explosion was estimated by the oblast's governor to be more than one billion rubles (or about $33 million US).
Chelyabinsk "was the first asteroid-impact disaster in human history,"...
Chelyabinsk asteroid crashed in space before hitting Earth: scientistsReutersBy Irene Klotz May 23, 2014 3:41 PMThe trail of a falling object is seen above a residential apartment block in the Urals city of Chelyabinsk, in this still image taken from video shot on February 15, 2013. REUTERS/OOO SpetszakazCAPE CANAVERAL Fla. (Reuters) - An asteroid that exploded last year over Chelyabinsk, Russia, leaving more than 1,000 people injured by flying glass and debris, collided with another asteroid before hitting Earth, new research by scientists shows.Analysis of a mineral called jadeite that was embedded in fragments recovered after the explosion show that the asteroid's parent body struck a larger asteroid at a relative speed of some 3,000 mph (4,800 kph)."This impact might have separated the Chelyabinsk asteroid from its parent body and delivered it to the Earth," lead researcher Shin Ozawa, with the University of Tohoku in Japan, wrote in a paper published this week in the journal Scientific Reports.The discovery is expected to give scientists more insight into how an asteroid may end up on a collision course with Earth. Scientists suspect the collision happened about 290 million years ago.Most of the 65-foot (20-meter) wide asteroid that blazed over Chelyabinsk in southwestern Siberia on Feb. 15, 2013, was incinerated in a bright fireball, the result of frictional heating as it dropped through the atmosphere at 42,000 mph (67,600 kph). But many small fragments survived.Workers repair damage caused after a meteorite passed above the Urals city of Chelyabinsk February 15, 2013. REUTERS/Yevgeni YemeldinovThe asteroid was traveling almost 60 times the speed of sound and exploded about 18 miles (30 km) above ground with a force nearly 30 times as powerful as the atomic bomb dropped by the United States on Hiroshima, Japan in 1945 in World War Two.The blast over Chelyabinsk caused shock waves that destroyed buildings and shattered windows. More than 1,000 people were injured by flying debris.Analysis of recovered Chelyabinsk meteorites revealed an unusual form of jadeite entombed inside glassy materials known as shock veins, which form after rock crashes, melts and re-solidifies.Jadeite, which is one of the minerals in the gemstone jade, forms only under extreme pressure and high temperature. The form of jadeite found in the Chelyabinsk meteorites indicates that the asteroid’s parent body hit another asteroid that was at least 492 feet (150 meters) in diameter.Scientists are still analyzing fragments of the asteroid and calculating its precise path toward Earth.A Russian policeman works near an ice hole, said by the Interior Ministry department for Chelyabinsk region to be the point of impact of a meteorite seen earlier in the Urals region, at lake Chebarkul some 80 kilometers (50 miles) west of Chelyabinsk February 15, 2013. REUTERS/Chelyabinsk region Interior Ministry/HandoutIn an email to Reuters, Ozawa described the Chelyabinsk meteorite as "a unique sample.”"It is a near-Earth object that actually hit the Earth, and its trajectory was well-recorded,” Ozawa wrote.The Chelyabinsk asteroid caused the second most powerful explosion in recorded history. In 1908, a suspected asteroid exploded with a force about 1,000 times more powerful than the Hiroshima atomic bomb, leveling some 80 million trees over 772 square miles (2,000 square km) near Russia’s Podkamennaya Tunguska River in Siberia.The first possible meteorites from the so-called Tunguska event were recovered just last year. Results have not yet been published.(Editing by Grant McCool)
