[meteorite-list] Griffith Observatory to reopen in 2005

[Robert Verish]

Southern California will be minus one of its most
viewed meteorite collections until the 
Griffith Observatory reopens in 2005.
News article follows:

"With flags waving and the sun glinting off shovels,
California Governor Gray Davis and Los Angeles Mayor
James Hahn joined other state and local officials in
breaking ground Wednesday, (October 30) for Griffith
Observatory's renovation and expansion project. The 
groundbreaking ceremony, attended by over 100 guests
and the John Marshall High School marching band,
officially begins 30 months of construction activity
at the Observatory. The project will fully restore the
1935 icon, completely transform the Planetarium
Theater, and more than double the Observatory's usable
public space through an addition underneath the front
lawn and western terrace.

Construction should be completed by mid-2005, followed
by installation and testing of new equipment and
exhibits; the Observatory is currently scheduled to
reopen in December 2005.  More than $58.6 million has
been secured thus far for the $83.0 million project."

Re: [meteorite-list] Asteroid Color Clans

[almitt]

Hi John,

I'll take a stab at this but Bernd really has great resources for answering this no
doubt better than I can. The topic that Bernd had started was on asteroid color clans
and that at least 90 percent of asteroids are associated with families (from
collisions in the past). No doubt the Vesta HED's are from chunks broken off from
Vesta in an impact and that have made their way into an orbit that upon further impact
has allowed meteoroids to end up in some of the kirkwood gaps where they can be
purbatrated into Earth crossing orbits. Yes they are from other sources but they
originated from the same source or asteroid. No doubt this is true for the other
related asteroid family groups and again the color clans that they are beginning to
piece together with the new research.

I don't know if we can say for sure or not if a certain meteorite is from a particular
asteroid chunk or fragment but there is very strong evidence to show the HED's are
indeed from Vesta and also a strong link of the H type chondrites to asteroid Hebe. I
don't think there is much doubt about the Mars type meteorites (SNC's) are from Mars
and the Lunar meteorites are from the moon as we have been there and have material to
compare to. With the color clans coming into play we can at least say that certain
meteorites are from certain families now.

On a related note Mar's moon Phobos is very similar to the CV3's like Allende but
there are also many other asteroids out there with that spectral match (could it be
the same clan?) I have always thought with the larger crater I see in the photos taken
by NASA that Phobos was a good candidate for that source material.

Another question or comment. Perhaps some of the meteorites of different classes
sample the same asteroid (or family, clan). We could have iron meteorites, pallasites
and chondrites or achondrites all from the same parent body but we are looking at
different depths of material all from the same parent body or asteroid family clan.
This is no doubt true of the meteorites we have from Vesta and shows material from
different depths. My best!

[meteorite-list] Annefrank Flyby A Success

[Ron Baalke]

Annefrank flyby a success
by Andrew Sengul
University of Washington Daily Online
November 4, 2002

A group of scientists, including UW astronomy professor Donald Brownlee,
spent last Friday and Saturday at the NASA Jet Propulsion Laboratory in
Pasadena, Calif., to coordinate an outer-space mission more than seven years
in planning. At a critical moment around 8:50 p.m. on Friday afternoon, the
Stardust spacecraft passed within 3,000 kilometers of an asteroid called
5535 Annefrank, sending photographs and other data back to Earth.

"It was a huge success," said Brownlee, the mission's chief scientist.
"Everything worked just great. We got tremendous pictures, better than what
we expected. When the spacecraft first came in, we were a little worried,
since we couldn't distinguish the asteroid from the stars, but once we got
closer, we could see it very clearly. It turned out that we were approaching
the asteroid's night side, and since all asteroids are different shapes, you
can't definitively say which side will be light and which side will be dark.
The pictures we got show that the Annefrank asteroid is a lot bigger and a
lot darker than we originally expected. It's about [seven] kilometers in
diameter, the same size as the asteroid that killed off the dinosaurs 64
million years ago."

While the Annefrank flyby excited scientists involved, this weekend's
operation only constituted a dress rehearsal of sorts for the Stardust
spacecraft's upcoming encounter with the comet Wild 2 (pronounced vild two).
On Jan. 2, 2004, the spacecraft will pass within 75 miles of this new comet,
close enough to capture some of the gas and dust surrounding its nucleus.
Traveling at about 13,400 mph, the spacecraft will capture particles
traveling many times the speed of sound.

"Basically, we got to see how all of Stardust's systems worked with this
encounter," said Brownlee. "With the asteroid flyby, we passed a major
milestone in the mission. After this, all Stardust has left to do is collect
the samples from Wild 2 and return to Earth."

Planning for the Stardust began in 1995, and the program was approved and
funded by NASA a year later, costing $200 million - a remarkably low price
for a space mission. Its main goal is to gather samples of dust from outer
space, hence its name. Wild 2 was chosen for sampling because it is the
easiest and most economical comet to reach from Earth.

"Comets are like ancient records of the history of our solar system,"
Brownlee said. "Most of them are in orbits far beyond our reach, and Wild 2
has only been in its current orbit since 1974. Its orbit used to span
between Jupiter's and Neptune's, but in 1974 it passed so near to Jupiter
that the planet's gravity altered its course, and now it orbits between
Jupiter and Mars."

The asteroid takes its name from Anne Frank, a Jewish teenager who recorded
her experiences hiding from the Nazis in Amsterdam during World War II in a
now-famous diary. It was discovered in 1942 by the German astronomer Karl
Reinmuth, three months before the Frank family first went into hiding, but
its current name was not given until long after the war ended.

Following its encounter with Wild 2, Stardust will return to Earth and
deposit its samples in a self-return capsule that will parachute to the
ground in Utah around Jan. 15, 2006. The Stardust project is the first
sample-return space mission in the United States since the last Apollo moon
landing in 1974.

"It's really exciting to have done this successfully," said Brownlee. "Doing
things like this in space takes a lot of talented people working very hard.
There's a lot that can go wrong in space, so when everything works out like
this, it's wonderful."

More information about the mission, along with an official press release
containing pictures of the asteroid, is available at

[meteorite-list] STARDUST Successfully Images Asteroid Annefrank During Dress Rehearsal

[Ron Baalke]

http://stardust.jpl.nasa.gov/news/news94.html

STARDUST Successfully Images Asteroid Annefrank During Dress Rehearsal
STARDUST Project
November 4, 2002 

Late Friday evening Pacific time on November 2, 2002 at
the Jet Propulsion Laboratory (JPL) in Pasadena, California, and at Lockheed
Martin Space Systems - Astronautics (LMA) near Denver, Colorado, the NASA
STARDUST flight team pulled off a tremendously successful close flyby of the
main belt asteroid Annefrank. This flyby was used as an engineering test of
the ground and spacecraft operations that will be implemented at the primary
scientific target, Comet Wild 2 (pronounced "Vilt" 2) just over one year
from now.

STARDUST is a low-cost Discovery Mission that continues to perform as
expected after more than three and a half years into a planned seven-year
mission to rendezvous with Comet Wild 2 in January 2004. STARDUST will
collect cometary dust samples, flowing from the nucleus just hours before
spacecraft flyby, and return the samples to Earth in a Sample Return Capsule
in January 2006. The close flyby of Annefrank offered a unique opportunity
to thoroughly test all planned operations on the spacecraft and ground
support operations which will be used during the rendezvous with Comet Wild
2.

"We performed a full dress rehearsal with the cometary dust collector
deployed as we flew STARDUST within 3,300 kilometers of Annefrank," said
Professor Donald Brownlee, the project's Principal Investigator from the
University of Washington. "The spacecraft was poised in its flyby attitude
with all the science instruments on. The flyby has exceeded all of our
expectations and provided us with unexpected data about the asteroid," said
Brownlee.

The approach geometry to Annefrank was much more difficult than will be the
case for Comet Wild 2. The spacecraft was pointed over 60 degrees off of the
normal Sun and Earth pointing attitude and was running on its battery
in order to attempt to detect and capture images of Annefrank.

"The spacecraft performed every command perfectly and did everything asked
of it," said Allan Cheuvront, Spacecraft Engineer at Lockheed Martin
Space Systems near Denver. "We are thrilled with how well the entire
operation went. We couldn't have asked for better performance from STARDUST
and the images it captured of the asteroid exceeded everyone's expectations.
The spacecraft's pointing, attitude and flight operations were excellent.
This really adds to our level of confidence about how well the spacecraft
will perform when we reach Wild 2," added Cheuvront. Cheuvront and a team of
engineers at Lockheed Martin's spacecraft control center, known as the
Mission Support Area, control the spacecraft in conjunction with JPL and the
Deep Space Network.

The Navigation Camera was straining to see Annefrank during approach. "This
camera was operating at its limit of performance and seeing very dim stars
down to about 11th visual magnitude", said Ray Newburn, the Lead Scientist
for the camera at JPL.

However, the brightness predicted by Drs. Stephen Synnott and Donald Yeomans
of JPL was dimmer than 11th visual magnitude. "We tried everything we could
think of including taking multiple long exposures and adding these on the
ground", said Dr. T. S. Mike Wang, Optical Navigation Specialist at JPL,
"but Annefrank was not cooperating. It was just too dim."

Because of the high probability of not seeing Annefrank during the approach,
the flyby was designed to be successful without having to see it up to 20
minutes from encounter. "A flyby distance of 3,000 km (1,864 miles) was
chosen so that there was no risk of the spacecraft flying near any possible
dust environment or small satellites of Annefrank", said Ed Hirst, JPL
Mission Design Manager. "We also wanted to ensure that Annefrank would be in
the camera view at the start of the encounter sequence," added Hirst.

Since Annefrank was not seen in the approach images, the flight team felt
that the asteroid was at least as dim as predicted and possibly even dimmer.
The team decided to send up a new encounter configuration file and set the
initial flyby exposures longer. "We had a planned uplink six hours before
encounter for this very purpose," said Robert Ryan, Mission Manager at JPL.
"We had some communications problems the day before that gave us some
difficulty, but NASA's Deep Space Network gave us highest priority, and
excellent communications on Friday, allowing us to play back earlier images
we missed as well as sending our final encounter commands," added Ryan.

At 8:00 pm (PST) Friday evening, communications were established with the
spacecraft to watch its pre-loaded sequence command turn the spacecraft away
from the Sun and Earth into its flyby attitude. "We have built up over three
years of flight experience and a tremendous amount of confidence and respect
for our spacecraft to perform such operations routinely," said Joe Vellinga,
STARDUST Program Manager at Lockheed Martin who led the dev

Re: [meteorite-list] Asteroid Color Clans

[John Divelbiss]

Hi Al, Rob, Bernd and others,

I think it is wonderful to think we can match types with asteroids that are
labeled and watched.

I have a question. Is it safe to say that what we are doing is matching
spectrums of types with those same specturms for a given asteroid, but not
necessarily committing to say that is probably from that asteroid. In other
words, their maybe(must be) several to hundreds of a given type asteroid out
there. And that one LL4 could come from one rock, and another from a
different rock with the same spectrum on the opposite side of the belt. I
maybe stating the obvious, but for instance I so often read that an HED is
probably from the asteroid Vesta, when in truth it maybe from another one.

I've read McSween and Norton's books amoung others, but I never read/heard
it stated like I'm trying to do...poorly.

Looking for input,

John

[meteorite-list] meteorites and rocks for sale

[John Divelbiss]

Hello All,
 
This is my first shameless plug for a listing of goodies for 
sale and due tomorrow night on ebay. Tonight will be the long version. The list 
has a couple meteorite slices including Gao, Dhofar 007 and NWA 904. http://members.ebay.com/aboutme/herman-75/  

 
I've also added some nice earthly material 
(olivine gabbro) which I liken to achondrites such as shergottite and 
diogenite. I've listed a few slices that are a cheap version of a nice 
slice of the good stuff. I know many of you could care less about such 
material, but I feel compelled to share what I think is great study material. 
Especially when comparing to achondrites. Based on its location in the 
field, this material is probably ancient ocean bedrock from the 
Pre-Cambrian time period, and maybe over a billion years old. I would 
like to think if we ever find meteorites on the moon from earth, it would be 
material similar to this. I also have listed a piece of magnetite rich 
gneiss (iron ore) which is stongly attracted to magnets. In the future I will 
also have more meteorites, thin sections of meteorites and gabbros, etc, and 
other types of earthly finds from the same area including peridotite, 
serpentenite, hypersthene-magnetite rich material, gneiss(es), etc. If any of 
you are interested in getting some of this great earthly material, contact me 
and I'm sure I could fix you up for a small price plus shipping. All of the 
material was field collected by me. Take care and thanx for 
reading.

[meteorite-list] Asteroid Annefrank

[Ron Baalke]

Hi,

We're going to be releasing a photo of Asteroid Annefrank today.
The asteroid was a bit dimmer than expected.  It did not
show up in any of the opnav images on approach (up to 12 hours
away), so we proceeded with the flyby with no course correction.
On the positive side, because it was dimmer, the asteroid
was about twice as big as expected.  Upon close approach, the 
autonav software on Stardust worked perfectly, and picked out the 
asteroid and centered the camera on the asteroid during the encounter.
Not surprisingly, Asteroid Annefrank is an irregularly-shaped
object, and craters are visible in the closer images.  There
is an indication Annefrank may be a contact binary.  I'll let
you know when the image is available.

There is LUN-A => lunar highland breccias (DaG 262, NWA 482)
There is LUN-B => lunar mare basalt (NWA 032, Dho 287)

O.R. Norton CEM, p. 253, Fig. 11.10:

"Comparison of reflection spectra of the CR2 chondrite, Renazzo
(solid curve), and the main belt asteroid 2 Pallas (open circles).
The match is almost perfect ..."

The author, N.M. Short, states that "The tiny 
crater was produced by a chemical explosion as part of an experiment to 
duplicate on a small scale the Meteor Crater itself."

Re: [meteorite-list] Asteroid Color Clans

[almitt]

Hi Bernd and all,

Bernd reported from a S & T article:

"at least 90 percent of asteroids are associated with families."

Which leads to the interesting topic of which meteorites sample which asteroids. So
far we have some good ideas where some of the meteorites are from. Examples are:

HED type meteorites probable sample asteroid Vesta
H type meteorites probably sample asteroid Hebe
L4 type meteorites may sample asteroid Eros
CM2 type meteorites may sample  Ceres
Aubrites may sample asteroid 3103 (44 Nysa) are there other klans?
M type asteroids (as asteroid Psyche) some of the iron meteorites types
A type asteroids (as asteroid Asporina) pallasite meteorite types

and of course we have the lunar (is there a classification category yet?) and Mars
(SNC's) meteorites

Can anyone add other links (weak or otherwise??) I know there is a link to the L6's
but can't find that right now.

Mostly borrowed from Harry McSweens book Meteorites and Their Parent Planets.
