Lyrics:
[Sagan]
If you wish to make an apple pie from scratch
You must first invent the universe
Space is filled with a network of wormholes
You might emerge somewhere else in space
Some when-else in time
The sky calls to us
If we do not destroy ourselves
We will one day venture to the stars
A still more glorious dawn awaits
Not a sunrise, but a galaxy rise
A morning filled with 400 billion suns
The rising of the milky way
The Cosmos is full beyond measure of elegant truths
Of exquisite interrelationships
Of the awesome machinery of nature
I believe our future depends powerfully
On how well we understand this cosmos
In which we float like a mote of dust
In the morning sky
But the brain does much more than just recollect
It inter-compares, it synthesizes, it analyzes
it generates abstractions
The simplest thought like the concept of the number one
Has an elaborate logical underpinning
The brain has it's own language
For testing the structure and consistency of the world
[Hawking]
For thousands of years
People have wondered about the universe
Did it stretch out forever
Or was there a limit
From the big bang to black holes
From dark matter to a possible big crunch
Our image of the universe today
Is full of strange sounding ideas
[Sagan}
How lucky we are to live in this time
The first moment in human history
When we are in fact visiting other worlds
The surface of the earth is the shore of the cosmic ocean
Recently we've waded a little way out
And the water seems inviting

Indonesia Meteor/Meteorite News- Bone, Indonesian ASTEROID 8OCT09 28OCT09
Space Weather News for Oct. 28, 2009
http://spaceweather.com
INDONESIAN ASTEROID: Earlier this month, with no warning, a ~10-meter wide asteroid hit Earth's atmosphere above Indonesia and exploded. The break-up was so powerful, it triggered nuclear test ban sensors thousands of kilometers away. A just-released analysis of infrasound data shows that the asteroid detonated with an energy equivalent of about 50 kton of TNT, similar to a small atomic bomb. This significant impact has received relatively little attention in Western press.

*Asteroid explosion over Indonesia raises fears about Earth's defences*
*An asteroid that exploded in the Earth's atmosphere with the energy
of three Hiroshima bombs this month has reignited fears about our
planet's defences against space impacts.*

Published: 10:23AM GMT 27 Oct 2009
On 8 October, the rock crashed into the atmosphere above South Sulawesi,
Indonesia <http://www.telegraph.co.uk/news/worldnews/asia/indonesia
The blast was heard by monitoring stations 10,000 miles away, according
to a report by scientists at the University of Western Ontario
<http://neo.jpl.nasa.gov/news/news165.html
Scientists are concerned that it was not spotted by any telescopes, and
that had it been larger it could have caused a disaster.
The asteroid <http://www.telegraph.co.uk/science/space >, estimated to
have been around 10 metres (30ft) across, hit the atmosphere at an
estimated 45,000mph. The sudden deceleration caused it to heat up
rapidly and explode with the force of 50,000 tons of TNT.
Luckily, due to the height of the explosion -- estimated at between 15
and 20 km (nine to 12 miles) above sea level -- no damage was caused on
the ground.
However, if the object had been slightly larger -- 20 to 30 metres (60
to 90ft) across -- it could easily have caused extensive damage and loss
of life, say researchers.
Very few objects smaller than 100 meters (300ft) across have been
spotted and catalogued by astronomers.
Tim Spahr, director of the Minor Planet Center
<http://www.cfa.harvard.edu/iau/mpc.html > in Cambridge, Massachusetts,
warned that it was inevitable that minor asteroids would go unnoticed.
He said: "If you want to find the smallest objects you have to build
more, larger telescopes.
"A survey that finds all of the 20-metre objects will cost probably
multiple billions of dollars."
The fireball was spotted by locals in Indonesia, and a YouTube video
taken that day <http://www.youtube.com/watch?v=yeQBzTkJNhs > "appears to
show a large dust cloud consistent with a bright, daylight fireball",
according to the Ontario researchers.
An asteroid or comet fragment around 60 meters across is believed to
have been behind the Tunguska Event
<http://en.wikipedia.org/wiki/Tunguska_event >, a powerful explosion that
took place over Russia in 1908. The blast has been estimated at
equivalent to 10-15 million tons of TNT -- enough to destroy a large city.
The White House
<http://www.telegraph.co.uk/news/worldnews/northamerica/usa/barackobama/ >
is to develop a policy on the space object impact threat by October next
year.

Asteroid Impactor Reported over Indonesia

NASA/JPL Near-Earth Object Program Office
October 23, 2008
On October 8, 2009 about 03:00 Greenwich time, an atmospheric fireball
blast was observed and recorded over an island region of Indonesia. The
blast is thought to be due to the atmospheric entry of a small asteroid
about 10 meters in diameter that, due to atmospheric pressure, detonated
in the atmosphere with an energy of about 50 kilotons (the equivalent of
50,000 pounds of TNT explosives).
The blast was recorded visually and reported upon by local media
representatives. See the YouTube video at:
http://www.youtube.com/watch?v=yeQBzTkJNhs&videos=jkRJgbXY-90
A report from Elizabeth Silber and Peter Brown at the University of
Western Ontario indicates that several international very-long
wavelength infrasound detectors recorded the blast and fixed the
position near the coastal city of Bone in South Sulawesi, island of
Sulewesi. They note that the blast was in the 10 to 50 kT range with the
higher end of this range being more likely.
Assuming an estimated size of about 5-10 meters in diameter, we would
expect a fireball event of this magnitude about once every 2 to 12 years
on average. As a rule, the most common types of stony asteroids would
not be expected to cause ground damage unless their diameters were about
25 meters in diameter or larger.
A more extensive report by Elizabeth Silber and Peter Brown of the
University of Western Ontario is here.

On Oct 8, 2009, media reports appeared in the local press in Indonesia
concerning a loud air blast occurring near 11am local time (0300 UT).
Subsequent to these first media reports, additional English language
reports appeared suggesting the event was meteoritic.

http://www.thejakartapost.com/news/2009/10/08/blast-may-be-result-falling-space-waste-or-meteorite-lapan.html
Indonesian language reports more clearly identify a bright fireball,
accompanied by an explosion and lingering dust cloud as the origin of
the air blast. Finally, a YouTube video posted on the same day appears
to show a large dust cloud consistent with a bright, daylight fireball.

Based on these initial reports, a detailed examination was made of all
International Monitoring System (IMS) infrasound stations of the
Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO). From this
initial examination, a total of 11 stations showed probable signals from
a large explosion centered near 4.5S, 120E, with an origin time near
0300 UT on Oct 8, 2009, consistent with the media reports. This signal
was notable for having been (a) detected at many IMS stations, including
five at ranges over 10,000 km (and one at a nearly 18,000 km range) and
(b) being confined to very low frequencies. Both of these observations
suggest the explosion source was of very high total energy. All signal
motions were between 0.27 - 0.32 km/s, consistent with stratospheric
signal returns.
We have used the Air Force Technical Application Centre (AFTAC)
period-yield relation as described by ReVelle (1997) as the most robust
basic indicator of source energy. To generate measured periods, the
average periods of all phase-aligned stacked waveforms at each station
were measured, according to the technique described in Edwards et al
(2006). These periods were then averaged to produce a single, global
average period of 13.4 sec and the AFTAC yield relation applied; this
produced an average source yield of 31 kT of TNT. Averaging the
individual yields from all stations produces a mean source energy near
50 kT of TNT while using only the eight stations having the highest
signal-to-noise-ratio (SNR) and using the local observed periods of the
waveform at maximum amplitude produces a yield estimate of 40 kT of TNT,
all of which are basically consistent. It is important to note, however,
that the standard deviation of this measurement is nearly 30 kT. That
is, the best source energy estimate would be 40 +/- 30 kT TNT. Note that
much of this variation may be due to the signal emanating from different
portions of the fireball trail as observed at different stations; each
period measurement is a "sample" of the size of the cylindrical blast
cavity at that particular segment of the trail detected by any one
station. As such, the out of atmosphere yield for this event is likely
higher than these measurements suggest - very probably in the ~50 kT range.
The yield estimates based on infrasonic amplitude are very uncertain in
this instance as the propagation distances are much larger than is
typical and outside the range limits where such relations have been
developed (e.g. Edwards et al, 2006) and hence the period relationship
(which was generated using a dataset of nuclear explosions having yields
in this range) is more applicable.
Some examples of the detected and processed waveforms are shown in the
appendix.
Based on these infrasound records, it appears that a large (40-50 kT
TNT) bolide detonation occurred near 0300 UT on Oct 8, 2009 near the
coastal city of Bone in South Sulawesi, Indonesia. The infrasonic
geolocation is not precise enough to determine if the bolide was over
water or land, but it was relatively near the coast.
Follow-on observations from other instruments or ground recovery efforts
would be very valuable in further refining this unique event.
Using an average impact velocity for NEAs of 20.3 km/s, the energy
limits (10 - 70 kT) suggested by this analysis correspond to an object
5-10 m in diameter. Based on the flux rate from Brown et al (2002), such
objects are expected to impact the Earth on average every 2 - 12 years

Bright light in sky causes commotion
At 3:07 a.m. Tuesday, McPherson County Communicationsofficers received several reports from citizens and law enforcement officers
regarding a large blue light falling from the sky. Dispatchers spoke with
Saline and Reno County authorities and were advised that
they had also received reports of this phenomena.
The National Weather Service in Wichita, was
contacted and they advised they had received a report of this from Lincoln County.
The general consensus is that it was a meteorite, however there is no
determination as to where it made impact.

Workshop on Asteroid 2008 TC3- 28OCT09
Workshop on Asteroid 2008 TC3 Scheduled
http://asima.seti.org/2008TC3/workshop2008TC3.html
WORKSHOP ON ASTEROID 2008 TC3
University of Khartoum, Khartoum, Sudan
Dec 5-15, 2009
INVITATION
The University of Khartoum, Faculty of Sciences and Physics Department,
and the SETI Institute invite planetary astronomers and meteoriticists
to participate in a workshop dedicated to asteroid 2008 TC3. Asteroid
2008 TC3 was the first asteroid to be detected in space and subsequently
found to impact the Earth. Fragments were recovered in the Nubian Desert
of northern Sudan in the form of rare ureilite meteorites, called
"Almahata Sitta".
Goal of the workshop is to discuss the results from ongoing research
into the properties of asteroid 2008 TC3 when it was still in space, its
nature and origin, the asteroid's impact in Earth's atmosphere, the
subsequent recovery, and the analysis of the recovered meteorites. Talks
on the origin of ureilites are invited, as well as discussions on how to
adjust observing strategies to increase the likelyhood of future
discoveries of small asteroids on a collision course with Earth.
By accepting this invitation, researchers will have a chance to examine
the collection of recovered meteorites and discuss how best to proceed
with the investigation of this small asteroid.
The workshop will be held on the days of December 6 and 7, 2009. The
University invites participants to take part in a banquet on the evening
of December 6 [Earliest return flight would be afternoon December 8].
In the week following, from December 8 to 15, there will be a site visit
to the area where Almahata Sitta was recovered . An effort will be made
to expand the diversity of recovered materials by finding more of the
fallen debris. Participants are asked to bring clothes and strong shoes,
suitable for outdoor camping and hiking. The weather can be cold at
night (bring woolen hat). Bring medication for a bad stomach,
anti-musquito spray, and sun-screen.
Itinerary: Dec. 8 - travel to Almahata Sitta; Dec. 9-12 - field survey;
[optional: Dec 13 - morning travel back to Khartoum (10-hr trip, arrive
3 pm afternoon at the earliest)]; Dec 13-15 - sight seeing along Nile,
back in Khartoum 4pm afternoon Dec. 15.
Abstract and registration <http://atv.seti.org/registration2008TC3.html
deadline is *November 1, 2009*. Please do not delay.

Planetary mission sources say the Russian Space Agency will officially
delay launch of its sample return mission to the Martian moon Phobos
until 2011 because of delays with integration and test of the vehicle in
time to make its originally planned October launch window.
The delay also affects China's first mission to Mars. The 240 lb.
Chinese Yinghou-1 spacecraft was to be mounted atop the Russian
spacecraft for transport to Martian orbit where it was to be released
before the Russian spacecraft landed on Phobos. The mission was to have
been launched on board a Zenit heavy booster from the Baikonur
Cosmodrome between October 6-16.

Designed with its five primary elements stacked atop one another (see
graphic above) the Russian Phobos mission is one of the most daring
planetary flights ever planned by either the U.S. or former Soviet
Union. It is being built by the Lavochkin Association facility, which
has developed many previous successful Soviet planetary missions and
also builds Russian military spacecraft today.
Those elements include a planetary cruise stage and descent stage with
landing legs atop which are stacked an ascent stage and sample return
capsule. The Chinese spacecraft (not pictured) is to ride on platform
added above the sample capsule, but separated before the landing on Phobos.
The fully integrated spacecraft (see graphic below) has a launch weight
of more than 24,400 lb. including propellants. It is to fly to Mars
about 200 million mi. from Earth then land on the 15 mi. dia. moon that
orbits about 5,800 mi. above Mars.

Using a sample apparatus similar to that carried to Earth's moon on
three successful Soviet unmanned lunar landing missions, the Phobos
lander is to drill into the surface of Phobos to obtain a sample from as
deep as 3 ft. below the surface. The apparatus is also designed so
ground controllers using the spacecraft's television system can spot and
pick up rock pebbles for return to earth. Up to about 160 grams (5.5 oz)
of soil and rocks could be collected.
The sample is to be elevated to a soccer ball sized Earth return capsule
mounted atop a coffee table sized Earth return bus. Several days of
sample operations would be conducted before the ascent stage carrying
the Earth return capsule is fired off the lander. It will need only
about 22 fps of velocity to escape the small gravity of the moon.
Once back in the vicinity of Earth, the capsule would be separated from
the ascent stage and reenter the Earth's atmosphere for a parachute
landing and recovery in Australia.
Phobos is believed by many planetary scientists to be a captured
asteroid, but it could also be dotted with dust pockets of Martian
material that could have landed on Phobos after large meteor impacts on
Mars. This means that samples of the body could yield a bonanza of data
on the composition of both asteroids and Mars. That data is of
increasing importance given the emphasis being placed on other future
sample return flights, including possible manned missions, to asteroids
much closer to Earth, as well as Phobos and eventually Mars itself.
U.S. geologist Ray Arvidson of Washington University in St. Louis (a
member of both the NASA Mars rover and Phoenix lander science teams)
says he has been helping the Chinese develop standardized data formats
for the mission. This is so the data from the Chinese orbiter can be
used by international planetary scientists.
The scientific payload on the Chinese spacecraft consists of several
instruments including a camera with 660 ft. resolution to monitor
Martian dust storms. It also carries a plasma package with electron and
ion sensors along with a mass spectrometer, a magnetometer and
radio-occultation sounder.
The shift to 2011 means that the U.S., Russia and China will all be
flying major missions to Mars in that same timeframe. NASA's Mars
Science Laboratory (MSL) rover was also delayed to the late 2011 Martian
launch window because of its own development and test problems.

This conference will be the seventh in a series of meetings on
meteoroids and related topics, which have been held approximately every
three years since 1993. In 2007 the meeting was organized by the Institut
d'Estudis Espacials de Catalunya (IEEC) and the /Institut de Ciencies de
l'Espai (CSIC) /and was held in CosmoCaixa, the science museum of the
Obra Social Fundacio La Caixa in Barcelona, Spain. The topics covered
during that meeting included the origin, nature, evolution and dynamics of
solar system minor bodies, with special emphasis on the study of
micrometer- to meter-sized fragments of comets and asteroids.
The 2010 meeting programme is expected to have sessions which cover the
following areas:
- Observational techniques and meteor detection programs
- Meteor shower activity and forecasting
- Dynamics, sources and spatial distribution of meteoroids including
sporadic, swarm and interstellar meteoroids
- Meteoroid interactions with Earth and planetary atmospheres;
ablation, fragmentation, deceleration.
- Atmospheric effects induced by meteors; Physics and chemistry of
meteor interactions processes in the Mesosphere and Lower Thermosphere
- Astromineralogy: properties of meteoroids
- Interrelationships: meteoroids - IDPs - dust - micrometeorites -
meteorites
- Meteoroid flux and impact hazard; Hypervelocity impacts
on the moon and spacecraft
- Meteor studies in astrobiology: organics and delivery process
- New techniques for detections of meteors and fireballs
- Meteor detection including cameras, telescopes, lidar, seismic and
infrasound sensors
- Radar observations and large aperture radars
Both invited and contributed talks, will be included in the program. The
program schedule will encourage informal interchange between the different
research communities. Deadlines for registration and abstract submission
for contributed talks and posters will be
announced in the Fall of 2009.
