Witness NASA capsule's re-entry this weekend
rgj.com (Nevada)
January 10, 2006

When a NASA capsule hauling comet and interstellar dust plummets through
the Earth's atmosphere this weekend, residents in large sweeps of the
West will witness a cosmic spectacle.

During the Stardust capsule's blazing re-entry at 1:57 a.m. PST Sunday,
it will travel at 29,000 mph, making it the fastest man-made object to
return to Earth.

The 100-pound cargo will arc over Northern California toward Utah's
Dugway Proving Ground, a remote Army base southwest of Salt Lake City.

Residents in parts of Northern California, Oregon, Washington, Idaho,
Nevada and Utah should see the Stardust capsule as it streaks across the
pre-dawn sky.

Prime viewing will be along Nevada's Interstate 80 where residents can
view the capsule's front.

The capsule's glow is expected to shine as bright as Venus for 90
seconds. It will appear brightest over Carlin, a small mining city in
northeast Nevada.

The capsule will likely appear as a bright pink dot to the naked eye. In
certain places, those with telescopes may see the capsule pass in front
of the moon, appearing as a tiny dot trailed by a dark wave of hot air
and debris from its heat shield.

During the capsule's descent, a team of scientists aboard a NASA DC-8
aircraft will track it and measure its brightness.

[meteorite-list] After 3 Billion Miles, Stardust Returns Sunday Bearing Cosmic Dust Older Than The Sun

2006-01-10 Thread Ron Baalke

After 3 Billion Miles, Craft Returns Sunday Bearing Cosmic Dust Older
Than the Sun

By WARREN E. LEARY
New York Times
January 10, 2006

In a blaze across the night sky, it should be a spectacular homecoming
at the end of a very, very long journey.

After covering 2.88 billion miles over seven years, the Stardust
spacecraft is nearing home with its minute but precious cargo: samples
of what are believed to be the oldest materials in the solar system.

Tucked away in what looks like a giant fly swatter of a collector is
dust swooped up from a close encounter with the comet Wild 2 and an
accumulation of particles picked up in three circuits of the Sun.

"This has been a fantastic opportunity to collect the most primitive
material in the solar system," said Donald Brownlee of the University of
Washington, the principal investigator for the mission. "We fully expect
some of the comet particles to be older than the Sun."

Comets, icy bodies that normally inhabit a region near Pluto's orbit,
are made of material many scientists believe is virtually unchanged
since the Sun and the planets formed about 4.6 billion years ago.

Studying comets not only provides clues to how the solar system was
created but could also help explain how certain materials and conditions
combined to form life, researchers said.

"Comets are a library of our history," said Thomas Duxbury, project
manager at the National Aeronautics and Space Administration's Jet
Propulsion Laboratory in Pasadena, Calif., which is supervising the mission.

After its launching in 1999, the Stardust circled the Sun and flew by
Earth for a gravity boost to rendezvous with Wild 2 (pronounced vilt 2)
near Jupiter. On Jan. 2, 2004, the Stardust came within 149 miles of the
comet, deploying shields to protect itself from cometary dust while
extending a 160-square-inch collector filled with a material called
aerogel.

This low-density silicon material, composed of 99.8 percent air, gently
slowed and trapped particles without significantly altering or damaging
them. Stardust also spent 195 days collecting interstellar particles
that flow through the solar system.

The challenge now is to bring them home safely. If all goes as planned,
a capsule bearing the space dust will dive into the atmosphere early
Sunday morning and gently parachute the samples to the Utah desert.

But bringing the Stardust home will require an orchestrated sequence of
events, many of them performed autonomously by the spacecraft. Adding to
the tension is the fact that the Stardust return capsule is similar to
one released by an earlier NASA probe called Genesis, which crashed to
Earth in 2004 when its parachutes failed.

Collector plates that trapped solar particles during Genesis' two-year
mission were shattered and contaminated, but scientists are trying to
recover some of the science.

"We are convinced that this is not going to happen on Stardust," said
Edward Hirst, the mission's systems manager. "We took the lessons
learned on Genesis and looked at Stardust."

Both craft were built by Lockheed Martin and share some systems. But
engineers said that the faulty switch believed to have failed in
deploying parachutes on the more complex Genesis capsule passed testing
on Stardust before launching.

Nonetheless, Mr. Duxbury said, NASA has prepared contingency plans to
recover the samples in case the mission, which cost $212 million, ends
in a crash landing. "If we have an accident and land hard, we still
think we can get the science out," he said.

Stardust has begun its final preparations to come home. On Nov. 16, it
performed the first of three trajectory correction maneuvers aiming it
at a target area southwest of Salt Lake City. The second, Hirst said,
was performed Thursday and was a textbook maneuver. "After sifting
through all the post-burn data, I expect we will find ourselves right on
the money," he said.

The last adjustment, scheduled for Friday, will place the craft in a
re-entry corridor for a landing point within an ellipse measuring 47 by
27 miles.

Plans call for Stardust to release its 101-pound sample return capsule
on Sunday at 12:57 a.m. Eastern time, when the spacecraft is 68,805
miles from Earth. About 15 minutes later, the main spacecraft is to fire
thrusters that divert it from Earth into an orbit around the Sun.

Four hours after release, the three-foot-wide return capsule is to enter
the Earth's atmosphere at 410,000 feet above the Pacific. At 28,860
miles an hour, this will be the fastest a human-made object has ever
entered the atmosphere. At 200,000 feet, the capsule's heat shield will
reach a peak temperature of 365 degrees Fahrenheit, followed 10 seconds
later by peak deceleration as the capsule experiences 38 times the force
of gravity.

The fireball of the descent should be visible from areas in Northern
California, Southern Oregon, Northern Nevada, Southern Idaho and Western
Utah, depending upon clou

[meteorite-list] Scientists See Better, Fainter with New Keck Laser Guide Star

2006-01-10 Thread Ron Baalke

http://www.keckobservatory.org/news/science/060110_lgs/index.html
  
Scientists See Better, Fainter with New Keck Laser Guide Star
Keck Observatory

WASHINGTON, D. C. (January 10, 2006) A new sodium laser is giving 50
times more sky coverage to the atmospheric-correcting technology known
as adaptive optics on the Keck II telescope at Mauna Kea, Hawaii. The
laser lets scientists explore most of the sky with adaptive optics and
gives them the capability to study objects that were previously too
faint to be seen with the system. Since 1999, Keck Adaptive Optics has
provided 10 times more resolving power than what could otherwise be
achieved from the ground. The results are producing infrared images from
the ground comparable - and often better - than those taken from space.

"This has been the most exciting technological and scientific
breakthrough for the Observatory in the last decade. It may forever
change the way we do astronomy from the ground," said W. M. Keck
Observatory Director Fred Chaffee. "We are entering a new, extraordinary
era of discovery."

After just one year of regular scientific use, the Keck Laser Guide Star
Adaptive Optics system is producing spectacular results and advancing
research in several fields of astronomical study. Findings include the
discovery of new asteroids, moons and planetoids in our solar system,
the detection of new brown dwarf binary systems -- including a strange
new kind of binary, observations of physical processes taking place near
a supermassive black hole, and new findings about extremely distant
supernovae and young galaxies.

The technique of adaptive optics uses visible light from a bright star
to measure and correct for atmospheric distortions at infrared
wavelengths. But only about two percent of the sky has stars bright
enough to use with adaptive optics. The Keck Laser Guide Star system
overcomes this limitation by creating an artificial star anywhere in the
sky. The W. M. Keck Observatory is the only 8 10 meter class facility in
the world currently providing this capability to observers.

"The wish list for astronomers is pretty simple," said Dr. David Le
Mignant, adaptive optics scientist at the W. M. Keck Observatory.
"First, they want the highest-quality images that can possibly be
obtained. Second, they want to look anywhere they want to in the sky.
The laser guide star makes both these wishes come true."

Operating at nearly 1,000 times a second, the Keck adaptive optics
system minimizes the blurring effects of Earth's atmosphere to provide
infrared images 10 times better than what can be achieved from the
ground. Without any correcting technology, the best telescopes on Earth
are limited to an average "seeing" ability, or resolving power, of about
0.5 arcseconds, the equivalent of being able to distinguish an object
the size of a blueberry from 2.5 miles (4 km) away. But with adaptive
optics, atmospheric blurring is removed, producing a resolving power of
about 50 milliarcseconds or better. This improvement is like looking at
a penny from 2.5 miles away and being able to read the words, "ONE CENT"
and "Liberty" stamped on the coin.

"We are shattering a limitation for ground-based observations --
astronomers can now uncover and study fine structures in extremely faint
objects anywhere, within and beyond our galaxy, " said Dr. Le Mignant.
"This new data will particularly complement present deep sky surveys
which study the formation of galaxies in the universe."

More than 21 scientific results made possible with the Keck Laser Guide
Star system are presented today at the 207th meeting of the AAS in
Washington D.C. Among the many new significant findings discussed at
Special Session 98, "Seeing the Universe in a New (Sodium) Light":

  have used the Keck Laser Guide Star to discover three new
  satellites orbiting some of the largest objects in the Kuiper
  belt. The surprising properties of these moons suggest that they
  are formed very differently from the tiny moons known to orbit
  smaller Kuiper Belt Objects. (A. Bouchez, Caltech)

* At the center of our own Milky Way galaxy, the hostile environment
  around the supermassive black hole should make it difficult for
  stars to form, but a group of massive young stars has been
  detected and their origins are puzzling scientists. The problem
  has been dubbed "the paradox of youth." Now, UCLA scientists are
  able to measure how these young stars move across the sky with an
  unparalleled precision of only two kilometers per second, and
  determine, for the first time, the orbit of each of the young
  stars located more than a few light months from the black hole.
  Scientists are using the stars' orbits, which retain an imprint of
  their origin, to understand how and where these young stars may
  have formed. (J. Lu, UCLA)

Public to look for dust grains in Stardust detectors
By Robert Sanders, Media Relations

BERKELEY -- Astronomy buffs who jumped at the chance to use their home 
computers in the [EMAIL PROTECTED] search for intelligent life in the universe 
will soon be able to join an Internet-based search for dust grains 
originating from stars millions of light years away.

In a new project called [EMAIL PROTECTED], University of California, Berkeley, 
researchers will invite Internet users to help them search for a few dozen 
submicroscopic grains of interstellar dust captured by NASA's Stardust 
spacecraft and due to return to Earth in January 2006.

Though Stardust's main mission was to capture dust from the tail of comet 
Wild 2 -- dust dating from the origins of the solar system some 4.5 
billion years ago -- it also captured a sprinkling of dust from distant 
stars, perhaps created in supernova explosions less than 10 million years 
ago.

"These will be the very first contemporary interstellar dust grains ever 
brought back to Earth for study," said Andrew Westphal, a UC Berkeley 
senior fellow and associate director of the campus's Space Sciences 
Laboratory who developed the technique NASA will use to digitally scan the 
aerogel in which the interstellar dust grains are embedded. "Stardust is 
not only the first mission to return samples from a comet, it is the first 
sample return mission from the galaxy."

"Like [EMAIL PROTECTED], which is the world's largest computer, we hope 
[EMAIL PROTECTED] will also be a large computer, though more of a neural 
network, using brains together to find these grains," said Bryan Mendez of 
the Center for Science Education at the Space Sciences Laboratory. Mendez 
and Nahide Craig, assistant research astronomer at the laboratory, plan to 
create K-12 curricula around the [EMAIL PROTECTED] project and to reach out to 
local astronomy groups to boost participation.

Mendez and Craig will describe their educational outreach program in a 
poster session on Jan. 10 at the national meeting of the American 
Astronomical Society in Washington, D.C.

Based on previous measurements of interstellar dust by both the Ulysses 
and Galileo spacecrafts, Westphal expects to find approximately 45 grains 
of submicroscopic dust in the collector, a mosaic of tiles of lightweight 
aerogel forming a disk about 16 inches in diameter -- nearly a square foot 
in area -- and half an inch thick. Though those searching for pieces of 
Wild 2's tail will easily be able to pick out the thousands of cometary 
dust grains embedded in the front of the detector, finding the 45 or so 
grains of interstellar dust stuck in the back of the detector won't be so 
easy.

Thanks to a grant from NASA and assistance from the Planetary Society, 
however, Westphal and his colleagues at the Space Sciences Laboratory have 
created a "virtual microscope" that will allow anyone with an Internet 
connection to scan some of the 1.5 million pictures of the aerogel for 
tracks left by speeding dust. Each picture will cover an area smaller than 
a grain of salt.

"Twenty or 30 years ago, we would have hired a small army of microscopists 
who would be hunched over microscopes focusing up and down through the 
aerogel looking for the tracks of these dust grains," said Westphal. 
"Instead, we developed an automated microscope to scan the aerogel and 
hope to use volunteers we have trained and tested to search for these 
tracks."

The Web-based virtual microscope will be made available to the public in 
mid-March, even before all the scans have been completed in a cleanroom at 
Houston's Johnson Space Center. In all, Westphal expects to need some 
30,000 person hours to look through the scanned images at least four 
times. Searching each picture should take just a few seconds, but the 
close attention required as the viewer repeatedly focuses up and down 
through image after image will probably limit the number a person can scan 
in one sitting.

To insure that the volunteer scanners know what they're doing, each must 
pass a test where he or she is asked to find the track in a few test 
samples. To judge the reliability of each volunteer -- and to provide some 
reward in what for most will be a fruitless search -- the team also plans 
to throw in some ringers with and without tracks.

"We will throw in some calibration images that allow us to measure the 
volunteers' efficiency," Westphal said.

If at least two of the four volunteers viewing each image report a track, 
that image will be fed to 100 more volunteers for verification. If at 
least 20 of these report a track, UC Berkeley undergraduates who are 
expert at spotting dust grain tracks will confirm the identification. 
Eventually, the grain will be extracted for analysis. Discoverers will get 
to name their dust

Chinese Antarctica explorers discover 150 meteorites
People's Daily Online (China)
January 9, 2006

Since their first discovery of meteorite on Jan. 1, 2006, the explorers
with China's 22nd Antarctica expedition have found 150 meteorites on the
Grove Mountains.

Some of the meteorites discovered are of rare types. The biggest one
weighs 901g, according to Dr. Ju Yitai, captain of the team stationed on
the Grove Mountains.

Meteorite collection is an import mission for the explorers.

They aim to increase China's collection of Antarctica meteorites and
discover new and special types. Besides, they are also seeking unknown
meteorite-intensive areas in the enrichment areas formed through glacier
movement and melt.

Dr. Ju said meteorite collection is the main task for his team in the
first 20 days.

With improving weather, most team members have joined the collection
apart from other work. In the past couple of days, they picked as many
as 30 pieces each day. On Jan. 7, in particular, 70 pieces were found.

With millions of dust particles headed our way from space, scientists
could use a hand.

Make that 60,000 hands, give or take a few.

Researchers are asking for volunteers to observe the Stardust capsule as
it streaks through the atmosphere early Sunday with its precious cargo
of comet dust.

Although the resulting fireball could be brighter than Venus and set off
a sonic boom as it soars over Nevada and Utah, the view will not be as
spectacular from California, said Peter Jenniskens of the SETI Institute
in Mountain View, who is organizing the observations.

``The fireball will be relatively low in the sky,'' he said, ``and at
the time it reaches peak brightness we'll be seeing it from the rear.''

For the best shot, go to a dark spot with a clear view of the horizon to
the north, northwest and northeast. Bring binoculars or a camcorder, and
watch the clock: The capsule is scheduled to re-enter the atmosphere at
39 seconds past 1:56 a.m. PST, give or take four seconds.

Official observers can register on a Web site.

Meanwhile, scientists at the University of California-Berkeley are
trying to recruit 30,000 people to help find rare interstellar dust
particles in samples from the capsule.

Volunteers will use Web-based ``virtual microscopes'' on their home
computers to focus up and down through images, looking for tracks left
by particles in the fluffy aerogel that was used to collect and cushion
them.

If they get enough recruits, the job could be finished by late this
year, said Andrew Westphal, a researcher at UC-Berkeley.

``This project was born out of desperation,'' he said. Without the Web
technology, it would have taken an army of expert microscopists working
full-time for years to get the job done.

[meteorite-list] 'Mild' Collision Spawned Earth's Moon

'Mild' collision spawned Earth's moon
Maggie McKee
New Scientist
09 January 2006
 
The collision that spawned the Earth's moon was relatively mild, reveals
the longest and most detailed computer simulation ever done of the
impact. The research puts limits on the size and velocity of space rocks
that can lead to the formation of satellites in cosmic smash-ups.

Computer models suggest the Moon formed after an object the size of Mars
(just over half the diameter of Earth) crashed into Earth about 4.5
billion years ago. Debris from the impact formed a disc around Earth
that eventually coalesced to become the Moon.

But modelling the process realistically is extremely difficult, and
researchers have tried a variety of approaches. Most have used single
particles in the models to represent some larger number of real
particles, a method called Smoothed Particle Hydrodynamics (SPH).

But the best of these models use just a few thousand particles in the
debris disc, and therefore can not reveal detailed disc structures. As a
result, the models can only recreate conditions for less than a day
after the impact.
  
"Extreme" simulations

Now, researchers led by Keiichi Wada at the National Astronomical
Observatory of Japan in Tokyo have used another approach to model the
disc for about four days. They divided the disc into a three-dimensional
grid of boxes - each with its own properties, such as temperature and
density - and evolved the boxes over time. They ran two "extreme"
simulations - one in which the disc was made mostly of hot gas, and
another where it was mostly liquid and solid.

Both simulations behaved similarly for the first 10 hours after the
initial impact, with the damaged impactor circling back and hitting
Earth a second time, when it is destroyed. This accords with SPH models
as well, suggesting gravity is the dominant force in the early formation
of the disc.

But the two models begin to diverge after that. If the impactor
vaporises when it is destroyed, spiral shock waves are created that slow
down the disc's rotation. This allows the disc material to fall onto the
Earth and prevents the formation of a moon.
  
Trouble with models

In contrast, if the impactor produces mostly liquid or solid debris, the
shocks cannot slow the disc down enough to make it fall to Earth, and
the Moon is formed. The researchers suggest that any impact powerful
enough to vaporise the impactor would not form a satellite.

In the case of the Earth, they estimate the Mars-sized object must have
been travelling at less than 15 kilometres per second. In more general
terms, they conclude that if an impactor is more than a few times the
mass of Earth, then "the giant impact never results in forming a large
satellite".

Scott Kenyon, an astronomer at the Smithsonian Astrophysical Observatory
in Cambridge, Massachusetts, US, says the conclusion is reasonable. "The
gaseous disc would most likely collapse faster than a solid or liquid
disc," he told New Scientist.

But he points out that astronomers have long struggled with modelling
the viscosity of gas in rotating discs. He says all models have this
problem, but that the 3D grid approach may be more vulnerable to it
because the viscosity must be chosen by the researchers, and the value
selected could affect the timescale over which the disc falls to Earth.

Tom,

I got it as well.  He forgot to take his meds.  He
does this everytime he forgets. For the record, the
first name is Urine.  Forward his spam back to him. 
If we all do that everytime, we can at least stuff his
mailbox.  He won't quit with a polite request.  I've
tried that.

Cheers,
Norm

Just use the killfile that surely all e-mail clients have.  Then you will never 
hear from him again
(that's what worked for me).

Re: [meteorite-list] Göran Lindfors again!!

2006-01-10 Thread Göran Axelsson
Well, I think I'm one of the lucky ones then, the last mail I got from 
Göran Lindfors said that I was an amateur and that he would never ever 
again answer my mails.  ...boo hooo, how sad I am... :-)



If he still uses the tele2 address I suggest that you all mail his ISP 
and complain to them directly. They have a web page for reporting abuse. 
It is all in Swedish (stoopid swedes!) but you could also mail them 
directly at [EMAIL PROTECTED] describing the problem in english.



If you want to take a shot at the web page, here is short instructions 
for using the web page:


Follow this link: http://www.tele2.se/abuse
Click on the "kontaktformulär" (contact form) and a new window will pop up.

The first field is for customers of Tele2, leave it empty.
Second field "Din e-postadress för ev. återkoppling" (Your email address 
for possible reply) Fill in your email address.
Third field, "Vad gäller ärendet?" (What's the issue?) Select "Spam" or 
"trakasserier" (harassment) as you feel.
Datum is date, the format is year - month - day  hour : minute. Fill in 
some time you got an email.
The last field is "Beskriv kortfattat vad du vill anmäla" (Describe 
shortly what you want to report) Tell them your complaints. English is 
okay, virtually everyone in Sweden speaks english.

Press "Skicka till Abuse" (Send to abuse).

Now you get a "Tack för din anmälan" (Thanks for your complaint)

Hopefully they will do something about it.

Feel free to ask for more help if you need.

Good luck!

/Göran, no not that one

Congratulations Jan!

You are now a member of an elite inner circle of meteorite people targeted by a
