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.

After registration (and sending us your passport pdf), you will receive
a letter of invitation from the University and a visa approval number
from the Ministry of Foreign Affairs in Sudan that should help expedite
the visa process. If there are any questions, please feel free to

Russian/Chinese Mars Mission Rescheduled for 2011- 27OCT09

Joint Russian and Chinese Mission to Mars Slips to 2011


http://www.spaceflightnow.com/news/n0909/19phobos/


Joint Russian and Chinese mission to Mars slips to 2011
BY CRAIG COVAULT
SPACEFLIGHT NOW
September 20, 2009

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.

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

Comets May Give Life a Hand

Summary: A comet hitting Earth would seem to bring only death and
destruction, but one group is studying how such an impact could promote
certain necessary chemical steps in the origin of life. The researchers
are focusing on how comet collisions might have influenced the molecular
orientation, or handedness, of our planet's biology.

Billions of years ago, comets may have ferried life-sustaining water to
our planet's surface, but that may not be all that we should thank these
dirty snowballs for. Researchers are simulating comet impacts to see if
they might help proliferate the left-handedness in molecules that life
on Earth depends upon.

There is evidence from meteorite studies that amino acids may have been
delivered to Earth from space.

"There is interest in how these building blocks
came to be on primordial Earth," says Jennifer Blank of the SETI Institute.

She and her colleagues study comets as a second avenue for depositing
these biological compounds on Earth. Their current work, which is
supported by NASA's Exobiology and Evolutionary Biology Program, is
looking at how the fire and brimstone of a comet impact may benefit the
formation of complex molecules of a particular handedness.

Primordial Lab

Life on Earth uses 20 amino acids to build up the thousands upon
thousands of different proteins that perform a myriad of cell functions.
Astrobiologists often focus on the origins of amino acids in order to
understand where life may have come from.

One of the first experiments aimed at reproducing the primordial Earth
and its chemistry was undertaken by Stanley Miller in 1953. He was able
to synthesize amino acids using lightning-like discharges in a reducing
atmosphere of methane, ammonia and water - similar to what exists on
Jupiter.

Since that pioneering work, researchers have come to believe that
Earth's early atmosphere was in fact more oxidative, containing mostly
nitrogen and carbon dioxide.

"Without the reducing atmosphere, the Miller mechanism becomes much less
efficient at producing amino acids," Blank says.

One way to get around this is to make the amino acids in space and have
them come crashing down on-board meteorites and comets. There is ample
evidence that meteorites carry amino acids. And just recently, an amino
acid was discovered in comet material brought back by NASA's Stardust
spacecraft.

Blank and her colleagues were curious as to what happens to these
biomolecules when the "space capsule" they are riding in smacks into the
Earth.

The team has focused their work on comets, rather than meteors. Although
comets are less prevalent in the inner solar system, they have a few
possible advantages over their dry rocky counterparts when it comes to
delivering biologically relevant material to a planet's surface.

First of all, a comet impact is thought to be less harsh than that of a
meteorite because comets are less dense, which means their impact
generates lower temperatures and pressures. Blank says that the blow
would be further softened on a comet arriving at an oblique angle.

The second advantage of comets is that they carry water, which is key
for the chemical reactions that beget life. When the comet lands, its
ice melts, forming a little puddle near the crash site.

"Comets give you all the ingredients, like a compact evolution kit,"
Blank says.

stationary target that contains an organic sample. The "comet" material
is then extracted and analyzed to determine what chemical reactions have
occurred.

Of course, the primordial Earth was stocked with its own water, but "if
a comet or meteor were to land in the ocean, any interesting chemistry
would quickly be diluted away," says co-investigator George Cooper of
NASA Ames. A comet impact on dry land would give the organic molecules
on board the chance to amplify their numbers in the localized puddle.

Like Shooting Comets in a Barrel

To simulate a comet hitting pay dirt, Blank and her colleagues fire a
bullet into a metal container the size of a can of beans. In this
scenario, the container is the comet and the bullet is the hard ground.
Inside the container is a small chamber about as big as a quarter, in
which the scientists place a liquid sample of organic molecules.

"It's not super high-tech, but it is rather involved as far as the
structural complexity is concerned," Blank explains.

She and her colleagues take special care to ensure that the metal
container doesn't leak from the impact. Afterwards, they carefully drill
down to the chamber and draw out their "shocked" liquid sample.

In 2001, the team reported that amino acids placed in the comet
simulator were still intact following the impact, which surprised
other scientists.

"It's the coolest thing," Blank recounts. "People told us, 'Nothing is
going to survive, so why should we fund you?'"

Normally, the 1,000-degree-temperatures inside the smashed "comet" would
destroy any amino acids. But Blank believes the temperature rises and
falls too fast for the molecules to react. There is also enormous
pressure of 10,000 atmospheres that may be preventing the breakdown of
compounds.

However, the amino acids did more than just survive the crash. They also
started bonding together to form short chains up to 5-amino-acids long.

This comet-induced bonding may have played a role in the origin of life.
Typically, there is an energy barrier that prevents amino acids from
latching together. Indeed, organisms require enzymes to overcome this
barrier when putting together their proteins. But enzymes themselves are
proteins, so there is a bit of a chicken-and-egg problem: how do you
build up proteins before you have proteins to help build them up?

It is perhaps conceivable that a comet impact fused together the first
rudimentary protein pieces (called "peptides") and thereby got the whole
ball rolling.

Blank's group is now running simulations to see if they can model how
the energy barrier to amino acid bonding changes under the high
temperature and pressure of a comet impact.

Molecular Crash-Test Dummies

The scientists are also planning to do more comet crash tests. They will
be looking at sugars, which play an important part in the structure of
DNA and RNA. And they will be looking at amino acids again, this time
studying whether the handedness of comet passengers might be affected by
the impact.

In regard to the handedness, Blank thinks there might be a difference in
how the amino acids hook up together during the impact. Left-handed
amino acids may form chains more readily with other left-handed amino
acids, rather than with right-handed ones.

Such a preference, if it exists, might be able to enhance a slight
overabundance of one hand (a so-called enantiomeric excess in the original
comet material. This might explain why organisms only use left-handed
amino acids to form proteins.

"It will be a great discovery if they can get definite evidence as to
formation of sugars, peptides, or enantiomeric excess," says Yoshihiro
Furukawa of Tohoku University in Japan, who was not involved with this
work.

He says the one concern will be contamination of the sample with the
left-handed biology we are already familiar with. He suggests using
amino acids made with carbon-13, so that any subsequent contamination
with normal carbon-12-based amino acids will be easy to detect.
