Re: [meteorite-list] Do we have an accurate number of finds from Lotus/ Coloma?

[Richard Montgomery]

Apologies to Brien Cook for my earlier post asking for pictures of his find; 
which have already been posted, graciously thank you, and with congrats, are 
awesome.  (Quick fingers make fools of a keyboard author, in this case, me.)


Whoops...instead, I was hoping to see a pic of Peter Jenniskens 
run-over-in-the-Lotus-Park-parking-lot piece.


Peter, is there a possibility of seeing yours?

[meteorite-list] Cassini Finds Saturn Moon Phoebe has Planet-Like Qualities

[Ron Baalke]

http://www.jpl.nasa.gov/news/news.cfm?release=2012-119  

Cassini Finds Saturn Moon has Planet-Like Qualities
Jet Propulsion Laboratory
April 26, 2012

PASADENA, Calif. -- Data from NASA's Cassini mission reveal Saturn's
moon Phoebe has more planet-like qualities than previously thought.

Scientists had their first close-up look at Phoebe when Cassini began
exploring the Saturn system in 2004. Using data from multiple spacecraft
instruments and a computer model of the moon's chemistry, geophysics and
geology, scientists found Phoebe was a so-called planetesimal, or
remnant planetary building block. The findings appear in the April issue
of the Journal Icarus.

"Unlike primitive bodies such as comets, Phoebe appears to have actively
evolved for a time before it stalled out," said Julie Castillo-Rogez, a
planetary scientist at NASA's Jet Propulsion Laboratory in Pasadena,
Calif. "Objects like Phoebe are thought to have condensed very quickly.
Hence, they represent building blocks of planets. They give scientists
clues about what conditions were like around the time of the birth of
planets and their moons."

Cassini images suggest Phoebe originated in the far-off Kuiper Belt, the
region of ancient, icy, rocky bodies beyond Neptune's orbit. Data show
Phoebe was spherical and hot early in its history, and has denser
rock-rich material concentrated near its center. Its average density is
about the same as Pluto, another object in the Kuiper Belt. Phoebe
likely was captured by Saturn's gravity when it somehow got close to the
giant planet.

Saturn is surrounded by a cloud of irregular moons that circle the
planet in orbits tilted from Saturn's orbit around the sun, the
so-called equatorial plane. Phoebe is the largest of these irregular
moons and also has the distinction of orbiting backward in relation to
the other moons. Saturn's large moons appear to have formed from gas and
dust orbiting in the planet's equatorial plane. These moons currently
orbit Saturn in that same plane.

"By combining Cassini data with modeling techniques previously applied
to other solar system bodies, we've been able to go back in time and
clarify why it is so different from the rest of the Saturn system," said
Jonathan Lunine, a co-author on the study and a Cassini team member at
Cornell University, Ithaca, N.Y.

analyses suggest that Phoebe was born within the first 3 million years
of the birth of the solar system, which occurred 4.5 billion years ago.
The moon may originally have been porous but appears to have collapsed
in on itself as it warmed up. Phoebe developed a density 40 percent
higher than the average inner Saturnian moon.

Objects of Phoebe's size have long been thought to form as
"potato-shaped" bodies and remained that way over their lifetimes. If
such an object formed early enough in the solar system's history, it
could have harbored the kinds of radioactive material that would produce
substantial heat over a short timescale. This would warm the interior
and reshape the moon.

"From the shape seen in Cassini images and modeling the likely cratering
history, we were able to see that Phoebe started with a nearly spherical
shape, rather than being an irregular shape later smoothed into a sphere
by impacts," said co-author Peter Thomas, a Cassini team member at Cornell.

Phoebe likely stayed warm for tens of millions of years before freezing
up. The study suggests the heat also would have enabled the moon to host
liquid water at one time. This could explain the signature of water-rich
material on Phoebe's surface previously detected by Cassini. 

The new study also is consistent with the idea that several hundred
million years after Phoebe cooled, the moon drifted toward the inner
solar system in a solar-system-wide rearrangement. Phoebe was large
enough to survive this turbulence.

More than 60 moons are known to orbit Saturn, varying drastically in
shape, size, surface age and origin. Scientists using both ground-based
observatories and Cassini's cameras continue to search for others.

The Cassini-Huygens mission is a cooperative project of NASA, the
European Space Agency and the Italian Space Agency. JPL manages the
mission for the agency's Science Mission Directorate in Washington. The
California Institute of Technology in Pasadena manages JPL for NASA.

Re: [meteorite-list] HED crater name (was Mercury's new names...)

[MexicoDoug]

Dear list,

Speaking of names, I don't recall any posting the 'official name' of 
the suspected source crater for the HED's on Vesta ...


It's ... "Rheasilvia".

It's central uplift, Mount Rheasilvia (Rheasilvia Mons) is now the 
highest known mountain peak in the Solar sytem, on poor, pummeled, 
pockmarked petit planetoid Vesta.


What did it beat out (displace to #2)?  You guessed it, it kicked the 
Olympians off their acropodium: Mount Olympus (Olympia Mons), on Mars, 
a likely source crater for our igneous Martian meteorites ;-)  Vestalis 
Maxima rules, all hail!


Kindest wishes

MESSENGER Mission News
April 26, 2012

Dr. Seuss, Alvin Ailey among the Names Selected for 23 Mercury Craters

The International Astronomical Union (IAU) recently approved a proposal
from the MESSENGER Science Team to assign 23 new names to impact craters
on Mercury. The IAU has been the arbiter of planetary and satellite
nomenclature since its inception in 1919. In keeping with the
established naming theme for craters on Mercury, all of the newly
designated features are named after famous deceased artists, musicians,
or authors.

The newly named craters include:

   * Ailey, for Alvin Ailey (1931-1989), an American choreographer
 credited with popularizing modern dance and revolutionizing
 African-American participation in 20th century concert dance.

   * Aksakov, for Sergey Aksakov (1791-1859), a 19th-century Russian
 literary figure remembered for his semi-autobiographical tales of
 family life, as well as for his books on hunting and fishing.

   * Balanchine, for George Balanchine (1904-1983), one of the 20th
 century's most famous choreographers, a developer of ballet in the
 United States and the co-founder and ballet master of New York
 City Ballet; he wrote more than 400 ballets.

   * Ellington, for Edward Kennedy "Duke" Ellington (1899-1974), an
 American composer, pianist, and big-band leader who, over the
 course of a 50-year career, wrote more than 1,000 compositions. A
 major figure in the history of jazz, he also wrote music that
 stretched into other genres, including blues, gospel, film scores,
 popular, and classical.

   * Faulkner, for William Faulkner (1897-1962), considered one of
 the most important writers of U.S. Southern literature. A Nobel
 Prize laureate, he worked in a variety of media but is best known
 for his novels and short stories.

   * Fonteyn, for Margot Fonteyn (1919-1991), an English ballerina
 regarded as one of the greatest classical ballet dancers of all
 time. She spent her entire career as a dancer with the Royal
 Ballet, eventually being appointed "Prima Ballerina Assoluta" of
 the company by Queen Elizabeth II.

   * Grainger, for Percy Grainger (1882-1961), an Australian-born
 composer, arranger, and pianist who, during the course of a
 65-year career, played a prominent role in the revival of interest
 in British folk music in the early years of the 20th century.

   * Grotell, for Maija Grotell (1899-1973), a Finland-born ceramist
 and teacher known for her experiments in glaze technology and
 sometimes described as the "mother of American ceramics."

   * Henri, for Robert Henri (1865-1929), an American painter and
 teacher. He was a leading figure of the Ashcan School, an early
 20th century artistic movement best known for works portraying
 scenes of daily life in New York's poorer neighborhoods.

   * Holst, for Gustav Theodore Holst (1874-1934), an English
 composer most famous for his orchestral suite, 'The Planets".

   * Kofi, for Vincent Akwete Kofi (1923-1974), a Ghanaian sculptor
 who borrowed extensively from traditional African concepts of
 stylization, emphasis, distortion and symbolism.

   * Lismer, for Arthur Lismer (1885-1969), a Canadian painter and
 member of the Group of Seven, a team of artists famous for its
 paintings inspired by the Canadian landscape and for initiating
 the first major Canadian national art movement.

   * Magritte, for René Magritte (1898-1967), a Belgian artist and
 one of the most prominent Surrealist painters, whose works were
 characterized by particular symbols, including the female torso,
 the bowler hat, the castle, the rock, and the window.

   * Mendelssohn, for Jakob Ludwig Felix Mendelssohn (1809-1847), a
 German composer, pianist, organist, and conductor of the early
 Romantic period. Among his most famous works is "Overture to A
 Midsummer Night's Dream", which includes the "Wedding March".

   * Nabokov, for Vladimir Nabokov (1899-1977), a multilingual
 Russian writer. He wrote his first lite

[meteorite-list] First Mars Express Gravity Results Plot Volcanic History

[Ron Baalke]

http://www.esa.int/esaSC/SEM6HJNW91H_index_0.html

First Mars Express gravity results plot volcanic history
European Space Agency 
26 April 2012

Five years of Mars Express gravity mapping data are providing unique
insights into what lies beneath the Red Planet's largest volcanoes. The
results show that the lava grew denser over time and that the thickness
of the planet's rigid outer layers varies across the Tharsis region.
 
The measurements were made while Mars Express was at altitudes of
between 275-330 km above the Tharsis volcanic "bulge" during the closest
points of its eccentric orbit, and were combined with data from NASA's
Mars Reconnaissance Orbiter.

The Tharsis bulge includes Olympus Mons - the tallest volcano in the
Solar System, at 21 km - and the three smaller Tharsis Montes that are
evenly spaced in a row.

The region is thought to have been volcanically active until 100-250
million years ago, relatively recent on a geological timescale.

The large mass of the volcanoes caused tiny "wobbles" in the trajectory
of Mars Express as it flew overhead; these were measured from Earth via
radio tracking and translated into measurements of density variations
below the surface.  

Overall, the high density of the volcanoes corresponds to a basaltic
composition that is in agreement with the many martian meteorites that
have fallen to Earth.

The new data also reveal how the lava density changed during the
construction of the three Tharsis Montes volcanoes. They started with a
lighter andesitic lava that can form in the presence of water, and were
then overlaid with heavier basaltic lava that makes up the visible
surface of the martian crust.

"Combined with the varying height of the volcanoes, we can say that
Arsia Mons is the oldest, then Pavonis Mons formed and finally Ascraeus
Mons," says Mikael Beuthe of the Royal Observatory of Belgium and lead
author of the paper published in the Journal of Geophysical Research.

At Ascraeus Mons, however, the density of the lava decreased at a later
stage, so that the top of the volcano is of lower density."

The transition could reflect changes in heating beneath the surface in
the form of a single mantle plume - an upwelling of abnormally hot rock
from deeper within the viscous mantle, created in a process that can be
likened to a lava lamp but on a gigantic scale - that slowly moved
sideways to create each of the three Tharsis Montes in turn. This is the
exact opposite of Earth where "plates" of crust move above a stationary
plume to form chains of volcanoes, such as the Hawaiian islands.

The data also describe the thickness of the lithosphere - the outermost
shell of the planet, including the upper portion of the mantle - and
find surprising lateral variations between Olympus Mons and the Tharsis
Montes, with the three smaller volcanoes having a much higher density
underground "root" than Olympus Mons.

These roots could be dense pockets of solidified lava or an ancient
network of underground magma chambers.

"The lack of a high-density root below Olympus Mons indicates it was
built on a lithosphere of high rigidity, while the other volcanoes
partially sank into a less rigid lithosphere," says co-author Veronique
Dehant, also of the Royal Observatory of Belgium. "This tells us that
there were large spatial variations in the heat flux from the mantle at
the time of their formation."
 
Since the three Tharsis Montes sit on top of the Tharsis bulge, whereas
Olympus Mons stands on the edge, the greater crustal thickness at the
centre may have acted as an insulating lid to increase the temperature,
creating a less rigid lithosphere. Here rising magma interacted with the
pre-existing bulge, whereas the magma forming Olympus Mons ascended
through the older crust that is supporting the Tharsis bulge, perhaps
creating the observed density differences between the volcanoes.

"These results show that data on the Mars interior are key to
understanding the evolution of the Red Planet," says Olivier Witasse,
ESA Mars Express Project Scientist. "One option for a future mission to
Mars would be a network of small landers, simultaneously measuring
seismic activity in order to probe the interior."

Re: [meteorite-list] Sutter's Mill meteorite hunt

[Michael Farmer]

All I have found is a rattlesnake.
The fragments I have I bought. Heavy rain all night last night, but clear from 
now on. Perhaps today I'll get mine.

[meteorite-list] Dr. Seuss, Alvin Ailey among the Names Selected for 23 Mercury Craters

[Ron Baalke]

http://messenger.jhuapl.edu/news_room/details.php?id=219

MESSENGER Mission News
April 26, 2012

Dr. Seuss, Alvin Ailey among the Names Selected for 23 Mercury Craters

The International Astronomical Union (IAU) recently approved a proposal
from the MESSENGER Science Team to assign 23 new names to impact craters
on Mercury. The IAU has been the arbiter of planetary and satellite
nomenclature since its inception in 1919. In keeping with the
established naming theme for craters on Mercury, all of the newly
designated features are named after famous deceased artists, musicians,
or authors.

The newly named craters include:

* Ailey, for Alvin Ailey (1931-1989), an American choreographer
  credited with popularizing modern dance and revolutionizing
  African-American participation in 20th century concert dance.

* Aksakov, for Sergey Aksakov (1791-1859), a 19th-century Russian
  literary figure remembered for his semi-autobiographical tales of
  family life, as well as for his books on hunting and fishing.

* Balanchine, for George Balanchine (1904-1983), one of the 20th
  century's most famous choreographers, a developer of ballet in the
  United States and the co-founder and ballet master of New York
  City Ballet; he wrote more than 400 ballets.

* Ellington, for Edward Kennedy "Duke" Ellington (1899-1974), an
  American composer, pianist, and big-band leader who, over the
  course of a 50-year career, wrote more than 1,000 compositions. A
  major figure in the history of jazz, he also wrote music that
  stretched into other genres, including blues, gospel, film scores,
  popular, and classical.

* Faulkner, for William Faulkner (1897-1962), considered one of
  the most important writers of U.S. Southern literature. A Nobel
  Prize laureate, he worked in a variety of media but is best known
  for his novels and short stories.

* Fonteyn, for Margot Fonteyn (1919-1991), an English ballerina
  regarded as one of the greatest classical ballet dancers of all
  time. She spent her entire career as a dancer with the Royal
  Ballet, eventually being appointed "Prima Ballerina Assoluta" of
  the company by Queen Elizabeth II.

* Grainger, for Percy Grainger (1882-1961), an Australian-born
  composer, arranger, and pianist who, during the course of a
  65-year career, played a prominent role in the revival of interest
  in British folk music in the early years of the 20th century.

* Grotell, for Maija Grotell (1899-1973), a Finland-born ceramist
  and teacher known for her experiments in glaze technology and
  sometimes described as the "mother of American ceramics."

* Henri, for Robert Henri (1865-1929), an American painter and
  teacher. He was a leading figure of the Ashcan School, an early
  20th century artistic movement best known for works portraying
  scenes of daily life in New York's poorer neighborhoods.

* Holst, for Gustav Theodore Holst (1874-1934), an English
  composer most famous for his orchestral suite, 'The Planets".

* Kofi, for Vincent Akwete Kofi (1923-1974), a Ghanaian sculptor
  who borrowed extensively from traditional African concepts of
  stylization, emphasis, distortion and symbolism.

* Lismer, for Arthur Lismer (1885-1969), a Canadian painter and
  member of the Group of Seven, a team of artists famous for its
  paintings inspired by the Canadian landscape and for initiating
  the first major Canadian national art movement.

* Magritte, for René Magritte (1898-1967), a Belgian artist and
  one of the most prominent Surrealist painters, whose works were
  characterized by particular symbols, including the female torso,
  the bowler hat, the castle, the rock, and the window.

* Mendelssohn, for Jakob Ludwig Felix Mendelssohn (1809-1847), a
  German composer, pianist, organist, and conductor of the early
  Romantic period. Among his most famous works is "Overture to A
  Midsummer Night's Dream", which includes the "Wedding March".

* Nabokov, for Vladimir Nabokov (1899-1977), a multilingual
  Russian writer. He wrote his first literary works in Russian, but
  rose to international prominence for the novels he composed in
  English; his "Lolita" is frequently cited as one of the most
  important novels of the 20th century.

* Nureyev, for Rudolf Nureyev (1938-1993), a Russian dancer,
  considered one of the most celebrated ballet dancers of the 20th
  century and credited with expanding the role to the male ballet
  dancer who once served only as support to the women.

* Pasch, for Ulrica Fredrica Pasch (1735-1796), a Swedish painter
  and miniaturist and one of the few female artists known in
  Scandinavia before the 19th century. She was a member of the Royal
  Swedish Academy of Arts.

* Petipa, for Marius Petipa (1818

Re: [meteorite-list] Sutter's Mill meteorite hunt

[Guenther]

Hi Mike,

Only 15 grams from such a large fall? Wow! That means that there must be
lots left to find. Maybe it's already been posted but what is the total
estimated weight of the fall?

I plan to go soon myself and I wonder if the GPS locations of specimens
found are being cataloged yet? Although, I imagine that it would be a bitter
sweet thing to have all the finds cataloged this soon.

Thanks for the update,

Abe Guenther

Day two of the meteorite hunt ended with no new finds other than a few
fragments of the parking lot specimens here in California. Many people are
here, some new faces, most well known, all hunting for the fall of a
lifetime, a CM2, only California's third fall. 
I walked many miles today, with nothing to show but sore feet,  but i did
buy out ~1gram of fragments recovered from the parking lot piece found by
Dr. Jeniskens. more pieces were scattered in the lot.
Sadly this rarest of rare meteorites fell in one of the toughest terrains I
have ever had the displeasure of searching for meteorites in. As of right
now less than 15 grams has been found despite large scale search.  Of course
that could change at any moment with the right find. 
So far it has been fun, i almost stepped on small rattlesnake today, so be
careful, he did not rattle. Police were involved in a couple of hunters day
for innocent reasons, seems landowners called cops even when hunters had
permission, people are kind of private up here, and park rangers were
getting interested in people hunting for rocks. It could get interesting
really fast with tomorrow's barrage of news that is coming down the pike.
Still, this is one of the rarest falls on my lifetime, and worth working
oneself nearly to death to try and find. i hope as much as possible is
recovered for the science that can be done.
Congrats again to Robert Ward for finding the first smallest needle in the
worlds largest haystack, something that 50 people today did not duplicate.
