The NYT is...the same publication that put out that hit-piece against meteorites last year where all of us were declared as a "black market" of illegal activity. It was little else besides slanderous statements, half-truths, and propaganda...
I recall the IMCA even wrote an official statement to rebut the lies and errors in the NYT article. You know an article is really really bad when the meteorite community feels it necessary to put together and release an official rebuttal.
Of course, this NYT article will get picked up by tons of news wires and aggregators who will republish and churn it back out endlessly. While it's new, unknowing people will repost and "like" or "recommend" the article on Facebook, further spreading the misinformation via social media. It's like a dirty...virus and I'm sure I won't be the only one today playing "damage control" on Facebook with this latest NYT torpedo-job.
This type of event is what makes me excited to wake up every morning and be involved in some small way with the world of meteorites and meteoritics. It's the reason almost everyone reading this is a member of a mailing-list like this - because Cherbarkul is what meteorite falls are all about. This is good good stuff and I loathe to see another rehash of the slanderous BS put out into the media. So if you are reading this, and later on you see a discussion in a forum/list/site somewhere about this event and somebody is quoting or referencing these error-filled NYT articles - please chime in politely but firmly and correct the misconceptions. It will be tedious, but it's necessary.
The problem is, there are a few bad apples in the meteorite world. But they are an extreme minority in relation to the greater numbers of reputable and decent people involved with meteorites. That is true for every group of people on Earth, no matter how big or small. If one chooses to be biased, selective, and narrowly-focus on a single negative anecdote, then anything can be made to look bad. The art of the "spin"....

Quote:Writeup from MB 101:Chelyabinsk 54°49’N, 61°07’E (approximate centroid)Chelyabinskaya oblast’, RussiaFell: 15 Feb 2013; 3:22 UTClassification: Ordinary chondrite (LL5)History: At 9:22 a.m. (local time) on February 15, 2013, a bright fireball was seen by numerous residents in parts of the Kurgan, Tyumen, Ekaterinburg and Chelyabinsk districts. Images of the fireball were captured by many video cameras, especially in Chelyabinsk. Residents of the Chelyabinsk district heard the sound of a large explosion. The impact wave destroyed many windows in Chelyabinsk and surrounding cities. Many people were wounded by glass fragments. A part of the roof and a wall of a zinc plant and a stadium in Chelyabinsk were also damaged. Numerous (thousands) stones fell as a shower around Pervomaiskoe, Deputatsky and Yemanzhelinka villages ~40 km S of Chelyabinsk. The meteorite pieces were recovered and collected out of snow by local people immediately after the explosion. The snow cover was about 0.7 m deep. The falling stones formed holes surrounded by firn snow. Largest stones reached the frozen soil. A stone may have broken the ice of Chebarkul Lake, located 70 km W of Chelyabinsk. Small meteorite fragments were found around the 8 m hole in the ice but divers did not find any stones on the lake bottom.Physical characteristics: The meteorite stones and fragments are from <1 g to 1.8 kg in weight and from a few mm to 10 cm (mainly 3-6 cm) in size. The total mass collected by local people is certainly >100 kg and perhaps > 500 kg. Fusion crusted stones are common. The fusion crust is black or brown and fresh. Broken fragments are rare. The interior of the stones is fresh but in some pieces there is evidence for weak oxidation of metal grains.Petrography: (D.D. Badyukov and M.A. Nazarov, Vernad). The majority (2/3) of the stones are composed of a light-colored lithology with a typical chondritic texture. Chondrules (~63%) are readily delineated and set within a fragmental matrix. The mean chondrule diameter is 0.93 mm. The chondrule glass is devitrified. The main phases are olivine and orthopyroxene. Olivine shows mosaicism and planar fractures. Rare grains of augite and clinobronzite are present. Small and rare feldspar grains show undulutory extinction, planar deformation features, and are partly isotropic. Troilite (4 vol.%) and FeNi metal (1.3 vol.%) occur as irregularly shaped grains. Accessory minerals are chromite, ilmenite, and Cl-apatite. A significant portion (1/3) of the stones consist of a dark, fine-grained impact melt containing mineral and chondrule fragments. Feldspar is well developed and practically isotropic. No high-pressure phases were found in the impact melt. There are black-colored thin shock veins in both light and dark lithologies.Geochemistry: (M.A. Nazarov, N.N. Kononkova, and I.V. Kubrakova, Vernad). Mineral chemistry: Olivine Fa 27.9±0.35, N=22; orthopyroxene Fs22.8±0.8Wo1.30±0.26, N=17; feldspar Ab86; chromite Fe/Fe+Mg=0.90, Cr/Cr+Al=0.85 (at.%). Major element composition of the light lithology (XRF, ICP-AS, wt%): Si=18.3, Ti=0.053, Al=1.12, Cr=0.40, Fe=19.8, Mn=0.26, Ca=1.43, Na=0.74, K=0.11, P=0.10, Ni=1.06, Co=0.046, S=1.7. Atomic ratios of Zn/Mn × 100=1.3, Al/Mn=8.8. The impact melt lithology has almost the same composition but it is distinctly higher in Ni, Zn, Cu, Mo, Cd, W, Re, Pb, Bi (ICP-MS).Classification: Ordinary chondrite (LL5), shock stage S4, weathering W0.Specimens: About 400 stones weighing 3.5 kg in total and a few thin sections are in Vernad.
