Two years on, source of Russian Chelyabinsk meteor remains elusive


Two years after a 20-meter rock slammed into the Earth after a meteoroid
dramatically fragmented in the atmosphere over the Chelyabinsk region in
Russia and injured hundreds of people, its parent asteroid remains
elusive, a new paper published in the journal Icarus shows. 

Astronomers had originally predicted that a 2-km near-Earth asteroid
(NEA) designated (86039) 1999 NC43 could be the source body from which
the Chelyabinsk meteoroid was ejected prior to its encounter with the
Earth. 

These two bodies shared similar orbits around the Sun, and initial
studies suggested even similar compositions, said Planetary Science
Institute research scientist Vishnu Reddy, lead author of Link Between
the Potentially Hazardous Asteroid (86039) 1999 NC43 and the Chelyabinsk
Meteoroid Tenuous that appears in Icarus.

However, reanalysis of the orbital parameters and spectral data by an
international team of researchers led by Reddy has shown that the link
between Chelyabinsk and 1999 NC43 is unlikely. The composition of
Chelyabinsk meteorite that was recovered after the event is similar to a
common type of meteorite called LL chondrites. However, the near-Earth
asteroid has a composition that is distinctly different from this,
Reddy said. 

They study also showed that linking specific meteorites to an asteroid
is extremely difficult due to the chaotic nature of the orbits of these
bodies.

Hi Carl and List,

Thank you for this update on the change.  However, what exactly does
this mean in practice?

For example, would a find with coordinates like Mreira now be
classified as a NWA 10xxx ?

Or will finds with firm reliable coordinates still be considered for a
place name and not a NWA 10xxx?

On this page, I can see the crossed out portion about NWAs that was
abolished.  But what else has changed in regards to policy about
classifying NWA material? - http://meteoriticalsociety.org/?page_id=59

Best regards,

2015-02-14 Thread Carl Agee via Meteorite-list
Hi Mike,

In a nutshell, the new rules allow geographic names for any Moroccan
meteorite with find coordinates. To simplify the naming in desert
areas, part of Morocco will have DCA grids. Under the new rules, any
meteorite without coordinates, originating in Morocco or surroundings
(meaning in practical terms purchased in Morocco) will be given a NWA
name. The new style NWAs will start with NWA 10001 to set them apart
from the old style NWA rules. There will be no retroactive names
assigned in this new scheme. Nothing will change in the naming of
falls, which will always have unique geographic names.

Hope this clarifies.

Carl

[meteorite-list] NWA 8159 in Tucson

2015-02-14 Thread Anne Black via Meteorite-list
I am curious.
I did look up this martian, NWA 8159 in the Met. Bulletin, odd rock with 
characteristics of all 3 of the SNC, so what is it?
An heterogeneous meteorite?
The missing link between all 3 martians?
A mixture of types, something like Almahata Sitta???

I did read the description on the Met.Bulletin but is there more written about 
it?  Any papers published yet?
Did anyone take any pictures of that rock?
Would any of that explain the surprising price of $15 000.00 a gram?

Still curious.

In a nutshell, from this point forward, DCA's will be created in the

From this point forward, new finds with coordinates will have DCA names.
That's what I get out of it!

Shawn, List,

This stuff:

http://www.huffingtonpost.com/2015/02/03/aliens-send-space-seed-to-earth_n_6

is just more of the same old Wickramasinghe nonsense, like the red rain of
Kerala State (India), which was nothing but bat blood in rain water, and the
more recent Diatoms from Outer Space claim. 

Just as we learned that Dr. Wickramasinghe could not recognize red blood
cells, we have now learned that he cannot recognize IDP's. Metallic
spherules are common and not an example of panspermia. Oh, and yes,
particles with a weak melt crust and a gooey center are a common type.

All we learn from this press release is that Dr. Wickramasinghe has moved
from the University of Wales in Cardiff to the University of Buckingham in
England. This serves the valuable function of informing  you whose
astrobiology press releases to ignore.

UK Scientists: Aliens May Have Sent Space Seeds To Create Life On Earth


Scientists in the U.K. have examined a tiny metal circular object, and are
suggesting it might be a micro-organism deliberately sent by
extraterrestrials to create life on Earth.

Don't be fooled by the size of the object in the microscopic image above. It
may appear to look like a planet-sized globe, but in fact, it's no bigger
than the width of a human hair.

The University of Buckingham reports that the minuscule metal globe was
discovered by astrobiologist Milton Wainwright and a team of researchers who
examined dust and minute matter gathered by a high-flying balloon in Earth's
stratosphere.

It is a ball about the width of a human hair, which has filamentous life on
the outside and a gooey biological material oozing from its centre,
Wainwright said, according to Express.co.uk. 

One theory is it was sent to Earth by some unknown civilization in order to
continue seeding the planet with life, Wainwright hypothesizes.

That theory comes from a Nobel Prize winner.

This seeming piece of science fiction -- called 'directed panspermia'
-- would probably not be taken seriously by any scientist were it not for
the fact that it was very seriously suggested by the Nobel Prize winner of
DNA fame, Francis Crick, said Wainwright.

Panspermia is a theory that suggests life spreads across the known physical
universe, hitchhiking on comets or meteorites.

The idea of directed panspermia was suggested by Crick, a molecular
biologist, who was the co-discoverer of the structure of DNA in 1953.
Twenty years later, Crick co-wrote -- with biochemist Leslie Orgel -- a
scientific paper about directed panspermia.

The abstract of their manuscript states:

Re: [meteorite-list] Important Announcement form the Nomenclature Committee

2015-02-14 Thread Jeff Grossman via Meteorite-list

To amplify on Carl's response...

For the past 15 years, any meteorite from this region (except falls) 
would get an NWA number unless there was compelling documentation of the 
coordinates of the find.  This might include a photo of the meteorite in 
situ with an active GPS.  But this was rarely presented to NomCom and so 
it rarely happened.


Now, like in other places around the world, NomCom will not question the 
coordinates of finds from Morocco and nearby countries (unless something 
is obviously wrong).  The meteorites will simply be named.  And like in 
other desert regions, this generally will mean DCA names.  There are no 
longer special rules for northwestern Africa.


We will have to see what happens.  The reason the NWA rule was put in 
place 15 years ago was that it wasn't possible to assess the find 
stories of all the meteorites coming out of the marketplaces in 
Morocco.  The rule changes take us back to that situation again, but now 
the nomcom will not even try to evaluate locations.  The difference now 
is that, with DCAs in place, there will not be hundreds of names to 
adjudicate.


As for the question about firm, reliable coordinates,  that will be 
for the reader to decide about any given meteorite.


The other thing that changed in the guidelines were special rules for 
assigning provisional names to NWA meteorites.  With nothing special 
anymore about NWAs, that went away (i.e., section 7.6 was revised).


The new NWA meteorite (N1) is no different than any other 
generically named meteorite.  Northwest Africa now means, literally, 
that the meteorite is most likely to come from the northwest quadrant of 
the continent, and not that it was most likely found in Morocco and 
adjacent parts of surrounding countries.  If nomcom is totally unsure of 
where a meteorite may come from, the name will be Nova xxx.

In a nutshell, the new rules allow geographic names for any Moroccan
meteorite with find coordinates. To simplify the naming in desert
areas, part of Morocco will have DCA grids. Under the new rules, any
meteorite without coordinates, originating in Morocco or surroundings
(meaning in practical terms purchased in Morocco) will be given a NWA
name. The new style NWAs will start with NWA 10001 to set them apart
from the old style NWA rules. There will be no retroactive names
assigned in this new scheme. Nothing will change in the naming of
falls, which will always have unique geographic names.

Hope this clarifies.

Carl

Hi Carl and List,

Thank you for this update on the change.  However, what exactly does
this mean in practice?

For example, would a find with coordinates like Mreira now be
classified as a NWA 10xxx ?

Or will finds with firm reliable coordinates still be considered for a
place name and not a NWA 10xxx?

On this page, I can see the crossed out portion about NWAs that was
abolished.  But what else has changed in regards to policy about
classifying NWA material? - http://meteoriticalsociety.org/?page_id=59

Best regards,
