[meteorite-list] Mars Exploration Rover Update - November 2, 2005

[Ron Baalke]

http://marsrovers.jpl.nasa.gov/mission/status.html#opportunity

OPPORTUNITY UPDATE: Dusty Weekend - sol 627-630, Nov 02, 2005:

The three-sol plan for Opportunity's sols 627 to 629 (Oct. 29 to 31,
2005) began well, with a drive of 51 meters (164 feet) on the first sol.
To allow as much time as possible for driving on that sol, the rover's
usual post-drive imaging from its new location had been planned for the
following sol. Overnight, Opportunity went into the deep-sleep mode for
saving energy. The morning after a deep sleep, the rover wakes up when
solar panels start putting out a prescribed level of energy. However, a
dust storm in the Meridiani region reduced sunshine enough on the
morning of sol 628 that Opportunity did not wake from deep sleep early
enough for the first scheduled activities of that sol. The rover's
onboard software properly put Opportunity into self-protective automode
for the day, so the rover did not take the post-drive images. Analysis
continued on Sunday, and the team uplinked commands on Monday to resume
activities. On sol 630, Opportunity successfully took pictures showing
the terrain surrounding its new position. Dustiness of the atmosphere
above Opportunity diminished a little on sol 630, as indicated by
increased output from the solar panels.

Sol-by-sol summaries:

Sol 627 (Oct. 29, 2005): In the first sol of a three-sol plan,
Opportunity drove 51 meters (164 feet). Wheel slippage averaged 3.7
percent, with a peak of 18 percent. Maximum tilt during the drive was
11.5 degrees. A dust storm in the Margaritifer region near Meridiani had
been noticed before plans were set for sol 627, so researchers had told
Opportunity to check the clarity of the atmosphere a few times during
the sol. Those observations saw a maximum atmospheric opacity ("tau") of
1.6, on a scale where 0 is perfectly clear, 1.0 is about as obscured as
a smoggy day in Los Angeles, and an earlier dust storm at Meridiani
reached 2.0 on sol 489. Opportunity's solar panels generated 593 watt
hours on sol 627. That is about 100 watt hours less than on recent days
before the dust storm, but still more than typical daily output during
winter. The rover used deep-sleep mode overnight.

Sols 628 and 629: Output from the solar panels did not climb high enough
to wake Opportunity from deep sleep until 7:38:50 in the morning, local
solar time. This was nearly five minutes too late for its first
scheduled activity of the day, turning on heaters to warm the miniature
thermal emission spectrometer. The rover realized it had woken up too
late, so it properly put itself into protective automode. It remained in
automode for sol 629. Solar panels' output was 479 watt hours on sol 628
and 470 watt hours on sol 629, indicating a diminished amount of
sunlight getting through the dust.

Sol 630: The team sent commands for activities originally planned for
sol 628. Opportunity returned to normal operations and took images of
the surroundings at the location it had reached on sol 627. Solar panels
produced 496 watt hours, which was enough to support an overnight UHF
communications pass in addition to the imaging activities.

As of sol 630 (Nov. 1, 2005), Opportunity had driven a total of 6373.6
meters (3.96 miles).

[meteorite-list] Methane-Producing Organisms Found in Utah Desert

[Ron Baalke]

http://www.usc.edu/uscnews/stories/11771.html

Work Bolsters Life on Mars Theories
By Lori Oliwenstein
USC Press Release
November 1, 2005

A Keck School scientist and his collaborators are the first to find
methane-producing bacteria in arid desert soils, providing a springboard
for future experiments on the distant planet.

Evidence of methane-producing organisms can be found in inhospitable
soil environments much like those found on the surface of Mars,
according to experiments undertaken by scientists and students from the
Keck School of Medicine of USC and the University of Arkansas and
published online in the journal Icarus.

The results, they said, provide ample impetus for similar "biodetection
experiments" to be considered for future missions to Mars.

"Methane-producing organisms are the ones most likely to be found on
Mars," noted Joseph Miller, associate professor of cell and neurobiology
in the Keck School and one of the study's lead researchers. "And, in
fact, methane was detected on Mars last year."

Methane is considered to be a biological signature for certain living
organisms that metabolize organic matter under conditions of low or no
oxygen.

Terrestrial methanogens (methane-producers) are typically found in
environments largely protected from atmospheric oxygen, such as peat
bogs, oceanic methane ices and anoxic levels of the ocean. But they
previously had not been detected in an arid desert environment.

To see if methane could be found in Mars-like soil, the investigators
collected soil and vapor samples from the arid environment of the Mars
Desert Research Station in Utah and then compared them with vapor
samples taken from the Idaho High Desert and soil samples from Death
Valley, the Arctic and the Atacama desert in Chile.

Three of five vapor samples from the Utah site showed the presence of
methane; there was no methane found in any of the vapor samples from
Idaho. Similarly, while five of 40 soil samples from Utah produced
methane after the addition of growth medium to the samples - indicating
that the methane was being given off by a biological organism, most
likely a bacterium - none of the other soil samples showed signs of
methane production.

Finding methane in the Utah desert is no guarantee that
methane-producers exist on Mars, said Miller, who previously has
analyzed data from the Viking Lander missions and found that soil
samples taken in the 1970s from the Martian surface exhibited a
circadian rhythm in what appeared to be nutrient metabolism, much like
that present in terrestrial microbes.

However, Miller said, this recent experiment does provide "proof of
principle [in that] it improves the case that such bacteria can and
might exist on the Martian surface." And, he added, that surely warrants
further investigation during future missions to Mars.

In conclusion, the researchers wrote, "The detection of methane,
apparently of biological origin, in terrestrial desert regolith bodes
well for future biodetection experiments in at least partially analogous
Martian environments."

If my memory serves me well enough even at my advanced age I saw meteorite
spheres carved out of what very probably was NWA 869, that stony L5 (P.S. is
there any official classification update with this special one?) "underdog",
at the Munich show. Never ever saw something like that before, besides the
popular and well-known Gibeon iron spheres, of course.

Now, if Asteroid models were to be carved from real meteorites, this one
might be a choice. But then again, I am quite sure I won´t buy one... :-)

[meteorite-list] Hayabusa's Scientific and Engineering Achievements during Proximity Operations around Itokawa

[Ron Baalke]

http://www.isas.ac.jp/e/snews/2005/1102.shtml

Hayabusa's Scientific and Engineering Achievements
during Proximity Operations around Itokawa

Japan Aerospace Exploration Agency (JAXA)
November 2, 2005

Hayabusa arrived at its exploration target, near Earth asteroid Itokawa,
on September 12th of this year after having been propelled there via ion
engines and an Earth swing-by. Since then, it has successfully performed
orbital maneuvers, precisely keeping its position relative to Itokawa.
The Hayabusa project team has made many discoveries while carrying out
their ambitious scientific observations of Itokawa. This release
summarizes and reports the major scientific and engineering achievements
in advance of Hayabusa's unprecedented and historic descent to the
surface of Itokawa for sample collection middle to later this month.

Hayabusa is a technology demonstration spacecraft focusing on key
technologies that are required for future large-scale sample and return
missions, yet is also making new scientific observations and
discoveries. The technology demonstration component of the mission
consists of five goals: ion engine propulsion in interplanetary cruise,
ion engine propulsion in combination with an Earth gravity assist,
autonomous guidance and navigation using optical measurements,
collection of surface samples in an ultra-low gravity environment and
the direct recovery of these samples on the ground after its return from
interplanetary flight. To date the Hayabusa project has accomplished
these demonstrations up through the third goal. Specifically, at the
time of arrival at Itokawa, Hayabusa had driven its proprietary new ion
engines for 26,000 hours, including their operation during an Earth
flyby. It has also perfectly completed a period of hybrid optical
navigation (Fig. 1) followed by precise guidance and
navigation of the spacecraft during its station keeping period around
Itokawa. (Fig. 2) These engineering achievements are the
primary mission of Hayabusa and their successful completion is a great
achievement.

The deep-space exploration technologies that the world's space agencies
are pursuing consist of three major elements: high efficiency electric
propulsion for cruise, rendezvous with target destinations and
round-trip flights back to the Earth. As of this time Hayabusa has
accomplished the first and second of these elements, leading the way for
the space exploration agencies of the world. Furthermore, robotic sample
collection and return from an extra terrestrial object has not been
executed before, and is not currently planned, except for Hayabusa,
which will attempt to gather a bulk sample from Itokawa. Hayabusa's
success clearly shows that Japan's deep space exploration technology has
reached the level of the world's most developed space agencies, and that
Japan is now in a leadership position in some select engineering fields.
Thus Hayabusa opens a new era in solar system exploration.

For the scientific aspects of the mission, Hayabusa carries four
instruments that have performed successful observations to date: AMICA,
a visible imager with multi-band filters has exposed 1,500 images
amounting to almost 1 GB of data, NIRS, a near infrared spectrometer has
taken 75,000 measurements distributed globally over the body, LIDAR, a
laser altimeter has accumulated 1.4 million measurements globally, and
XRS, a X-ray spectrometer has received and integrated its signal for 700
hours. In addition to these, spacecraft tracking data has been used to
measure properties of the asteroid as well. These unprecedented
scientific measurements are briefly described and reported in what follows.

(A) Morphological and geological discoveries about Itokawa: The a priori
theoretical assumption that small near-Earth asteroids should have
geologically homogeneous features was completely overturned by the
observation of a wide variety of surface features and types at Itokawa.
The surface is covered with huge boulders and, for the first time, naked
surfaces not covered with regolith have been exposed. (Fig. 3, 4, 5, 6,
7)  Previously visited asteroids were covered with thick
regolith, thus Itokawa's surface is like nothing that has seen before,
which is quite fortunate for the Hayabusa mission. The opportunity to
observe the true asteroid surface, which is usually concealed from view,
advances our understanding of spectroscopic observations of asteroids
taken from Earth, and allows us to expand our knowledge of near Earth
asteroids.

(B) Taking advantage of the observations made with the onboard
instruments, sufficiently detailed information about the sampling sites
has been obtained, and the relation between the potential samples and
the spectroscopic data has been correctly correlated. As a technology
demonstration mission, Hayabusa has already finished the preliminary
steps towards the primary sample and return goal. (Fig. 8) 
These samples will provide important scientific clues concerning the
puzzlingly inco

[Ron Baalke]

Asteroid ace keeps NASA grounded

Scientist works on plans to save Earth, even though it's not his job

By Alan Boyle
MSNBC
November 1, 2005

Planetary scientist Don Yeomans laughs at the title of "asteroid czar,"
but as the manager of NASA's Near-Earth Object Program, he's arguably 
the go-to guy for asteroids and other celestial objects that could 
blast us back into the Stone Age.

Over the past decade, Yeomans and his colleagues at NASA's Jet
Propulsion Laboratory in Pasadena, Calif., have had to cope with a
series of asteroid alerts - arising in part because astronomers are
getting so much better at spotting space rocks that have a chance of
crossing Earth's orbit sometime in the next century or two.

The biggest concern right now has to do with an asteroid called Apophis,
which will have a close encounter with Earth in 2029 and might even hit
us in 2036, depending on how its orbit changes between now and then.
NASA says Apophis will almost certainly miss Earth - but just in case,
Yeomans and other at the space agency have sketched out plans for space
missions to divert the asteroid if necessary.

NASA issued its plan as a response to concerns expressed by former
astronaut Rusty Schweickart, who is calling attention to potential
threats from near-Earth objects as the chairman of a California-based
group called the B612 Foundation.

Yeoman discussed Schweickart's concerns, NASA's response and the bigger
picture behind near-Earth objects on Tuesday in an interview with MSNBC.com.

During the discussion, he made clear that he doesn't let his status as
NASA's chief asteroid-watcher go to his head. For someone who watches
out for cosmic doomsdays, Yeomans seems remarkably grounded.


"Several months ago, the Pasadena newspaper did an article on strange
jobs, and I was there with a belly dancer, a tattoo artist and a dog
groomer," he said with a laugh. "So that's the kind of company I keep here."

He also keeps company with a growing array of skywatchers, including
researchers at JPL's own Near Earth Asteroid Tracking project in Hawaii, 
professionals at other facilities such as the Lincoln Near Earth Asteroid 
Research project in New Mexico - and hundreds of amateur astronomers 
around the world.

"Back in the early '90s and before that, this near-Earth object issue
was looked upon, even among our scientific colleagues, as sort of a
crazy topic," he recalled.

Some even thought NASA was using near-Earth objects as a ploy to get
more money, he said. But since then, asteroid-watching has gotten a lot
more respectable.

"We shouldn't be going hard over and devoting a lot more resources than
what we have now, perhaps," he said. "But the modest level of spending
that NASA is doing now - about $4 million a year - is probably
appropriate, at least for the time being, for the insurance that we get
as a result of tracking these objects into the future. We don't get the
giggle factor nearly as much as we once did."

Although the study of near-Earth asteroids has come a long way in the
past decade, one big question still hangs in the air: Who takes over if
Yeomans and his colleagues actually spot an asteroid or comet heading
our way?

At least officially, it's not NASA. True, NASA identifies and tracks
potentially threatening near-Earth objects, and NASA does have plans to
respond to Apophis if necessary. However, dealing with an actual threat
is not part of the space agency's job description, Yeomans said.

"NASA does not have the charter to look at that, nor does anyone else,"
he said. "That's the point - no one does at the moment."

What to do about Apophis? 

Here's the edited Q&A from Tuesday's interview, beginning with a
discussion of NASA's plans to divert Apophis if necessary:

MSNBC.com: It's interesting that there is a timetable for dealing with
this particular asteroid. Could you talk about the thinking that goes
into how you approach something like this, which is a very
low-probability but high-impact event?

Yeomans: The first point to be made is that the whole point of NASA's
near-Earth object search is to find these objects well in advance of any
threatening encounter. Once you have a couple of decades to work with,
this problem becomes tractable. So the object was discovered as part of
the program here, and we ran the orbit calculations forward and found
this close approach in 2029.

Then we discovered that depending on the circumstances of that close
approach in 2029, there could be what we call "resonant returns." In
2036, seven years after the 2029 return, the earth has gone around the
sun seven times, of course, and the asteroid would have gone around six
times. And they arrive at the same place at the same time, if the object
passes through a 600-meter [2,000-foot] "keyhole" in 2029. Now the
chances of that happening are pretty minuscule, but it hasn't been ruled
out yet.

The plan is to continue observations of this object, both optically and
with radar

Hi--If I had known the interest generated, I would have been a better 
observer--I did not record the time--It was Halloween evening and I was 
just about to close down for lack of trick or treaters--so guessing about 9 
or 9:30--from my location in the Hayfield Kingstowne area of Fairfax County 
VA--what I observed was SSW of my location, about 30 degrees or so above 
the horizon traveling in a WSW direction, It had the appearance of a very 
wide jet vapor trail--twice or so the normal width, but very 
luminescent-with a sort of bluish/pale yellow cast--my view of it was 
limited as line of sight was blocked by houses and trees after it passed.

Maybe one of these ;-)

Dhofar 733 (LUN-A) - anorthositic granulitic breccia
DaG 262 (LUN-A) - polymict anorthositic lunar highland breccia/
  contains maskelynite-rich clasts
Dhofar 287 (LUN-B) - plagioclase is totally converted to maskelynite/
   a low-Ti mare basalt, with similarities to Apollo 12 and 15 
basalts

Re: [meteorite-list] FIREBALL OVER NORTHERN VIRGINIA

[Francis Graham]

Dear List,
  At 8:40 PM Nov. 1 a Kent State student and myself
noticed a bright bolide directly to the south, from
Kent OH. 
  The sky was not very clear; horse-tail clouds were
still there at sunset, peppered with fog near the
ground at the time of viewing. So we thought the
bolide would have been seen much brighter but for
these conditions.
  Does anyone have a better time on this? Could they
be the same object? We thought it may have been a
satellite re-entry at the time.

[meteorite-list] Proposal: Joe Six Pack's Weathering Scale

[Martin Altmann]

One can't determine, but one can guess macroscopically
and if one has had a lot of stones in one's hand,
the later correct determination of the weathering degree, often is as
supposed :-)

Let's be constru- and instructive, that's what the list is for, and try to
built up together a scale for rough estimating without a microscope:

JSP - weathering scale (provisional)

W0 -
Black, dull fusion crust of silky to rough appearence. (or glossy shiny if
basaltic).
No stainings on the crust, if exist hairfine flightmarks.
If a fragment, sharpest edges, many different tiny "things" visible on the
broken surfaces, broken surfaces crumbly.
All what looks like metal has no brown rims around. No brown mottling after
cut.
Little Devil on shoulder says: "You MUST have it".

W1 -
Still black fusion crust, but shiny and smooth, like a little polished. Some
smaller brown areas on the crust possible, also metal grains lurking through
the crust.
interior and crust easy distingushable; side where it sat on the ground of a
different color;  little brown auras around metal grains.
Cut surface some brown mottling. Nothing red inside. Nice, nice

W2 -
Remainders of fusion crust, looking quite thick, shiny and not black
anymore. Fractured edges rounded. Fractured surfaces shiny and smoothened.
Pit's from chondrules visible there. Major parts of cut surfaces brown. Dirt
on bottom. Flight marks gone.

W3 -
No crust, rounded, desert varnish, light coloured caliche, where it was in
ground. Cracks possible. No tiny regmaglyptes visible. If cut, iside of more
or less uniform brown colour. If fragment, broken surfaces look like
undamaged parts.
To say it short, that stuff, which you find most, if you're wandering around
on a large fair and which let you shrug your shoulders.
Reads on ebay:  "beautiful stone"

W4 -
Like W3, but also often with deep cracks and clefts with rounded edge,
sometimes caliche inside or even tiny stones. Cut boring brown, with
sometimes some snot - People will say "I bought it from Bessey" (nooo, just
a jokus, he has a lot of fine stones tooo).
Reads on ebay "nice stone"

W5 -
You can break it up with one hand.
Reads on ebay "inetersting shape"

Let's work it out - more suggestions?
Buckleboo!
Martin

Just out of curiosity, how can you determine the
weathering level of a meteorite like this, which
lacks significant metal and sulfide?  The scale
up to W4 is defined by these and only these minerals:

>W0: No visible oxidation of metal or sulfide.  A

Re: [meteorite-list] New Lunar Meteorite Discovered - NWA 3163

[Greg Hupe]

Hi Jeff,

Thank you for your inquiry.

I had a discussion on the phone with the lead scientist last night regarding 
the weathering level of NWA 3163 would be after the question was brought up 
by a collector. He basically stated that due to the very low amount of 
caliche and virtually no interior staining, that he would suggest the 
weathering grade would be very low, perhaps W1 if he had to apply the grade 
(which he did not in his submitted classification).


We are still waiting for the terrestrial age. I know this does not determine 
the weathering level, but may help in this case due to the current 
weathering grade rules (as you kindly listed below). I suppose it is all up 
to interpretation for this type of meteorite and I guess one could compare 
this lunar meteorite to another similar one and could make an educated guess 
or suggestion of weathering level.


Perhaps the scientific community and/or NomCom can come up with a scientific 
way to determine weathering levels for meteorites of this type, which
lack significant metal and sulfide. They might be able to use the Apollo 
samples which have small clasts of the same material to use as a guide? Just 
a thought.


Best regards,

Greg

Re: [meteorite-list] Fred's TAN 057 a CK or a CV Chondrite?

[Meteoriteshow]

Dear Bernd and All,

Many thanks for your help in trying to understand what Tnz057 really is and 
providing many information about studies that have been
carried out already about CVs and CKs.
I will try my best in order to get more information about this meteorite, from 
labs that are willing to work on it and of course
will share the results (when available!) with the Meteorite List.
Any other comments & clues are welcome of course, my goal being to find out 
what we have recovered from the Tanezrouft: a CV4? a
CK4? a CK5?... or anything else??? One of the main interests is to me that it 
may bring some new information about the
classification of CVs and CKs, causing Scientitsts to face new questions. Isn't 
it exciting?
I agree that it does not fit completely to the criterias of classification as a 
CK (the most obvious points to me are the huge CAIs
and sharply defined chondrules that are present in this meteorite...) but it 
does not fit to the criterias of classification as a CV
as well. O isotopes have not been searched so far, maybe one day?
For all those reasons I really believe that before we get more information 
about the CK and CV groups, the classification reached by
Bertrand Devouard, Brigitte Zanda and Michele Denise is what had to be provided 
in the present knowledge that we have. The new
question is also about its metamorphism since UCLA concluded to a CK5... but 
once again this meteorite is quite heterogeneous (John
Wasson has seen the complete meteorite and various sections) and the partslices 
that have been used for the study on CK and R
chondrites is quite small and maybe not fully representative... I don't know as 
I'm not a scientist myself and I simply wonder,
taking the different results the way they come! And once again the fact that 
quite different conclusions are obtained is very
interesting, for a meteorite that is "anomalous" from its "head down to its 
toes"! (to mention Bernd's expression).

"May the Force be with Tnz057"!!!
Best regards,

Frederic
