Workshop and Field Excursion: Damage to Target Rocks During Impact Cratering

http://folk.uio.no/stephaw/cdws.html

Damage to target rocks during impact cratering
Oslo, Norway
Workshop: June 6-8, 2010
Field Trip: June 9-11, 2010

------------------------------------------------------------------------
MEETING LOCATION AND DATE
------------------------------------------------------------------------

The workshop will be arranged at PGP (Physics of Geological Processes)
http://lux.uio.no/pgp/

http://www.uio.no/

,
June 6-8, 2010, with an immediately following excursion to the Ritland
impact structure, southwestern Norway on June 9-11.

Please, be aware that June is high touristic season in Oslo, and it can
be difficult to find (inexpensive) housing. Make your bookings as early
as possible!

------------------------------------------------------------------------
SCIENTIFIC FORMAT
------------------------------------------------------------------------

The workshop will be organized in plenary sessions of presentations that
focus on:

1. Distribution and characterisation of rock damage measured in specific
craters

2. The process of rock failure itself - how do current models
incorporate rock mechanics and what are the pros and cons of different
methods?

3. Meso-/micro scale damage e.g. shatter cones (length scale meters),
planar deformation features, broken crystals, and pore space destruction

4. Local scale - fracture-fragmentation zone near crater-origin

5. Regional scale - the influence of pre-existing fault patterns on the
crater shape

6. The relationship between fragmentation of rocks in the vicinity of
impact craters and their observed geophysical signature.

We intend to have oral presentations and workshop/discussion sessions.
The detailed program will be announced later.

------------------------------------------------------------------------
CALL FOR ABSTRACTS

Asteroid to Fly by Within Moon's Orbit Thursday
Jet Propulsion Laboratory
April 06, 2010

A newly discovered asteroid, 2010 GA6, will safely fly by Earth this
Thursday at 4:06 p.m. Pacific (23:06 U.T.C.). At time of closest
approach 2010 GA6 will be about 359,000 kilometers (223,000 miles) away
from Earth - about 9/10ths the distance to the moon. The asteroid,
approximately 22 meters (71 feet) wide, was discovered by the Catalina
Sky Survey, Tucson, Az.

"Fly bys of near-Earth objects within the moon's orbit occur every few
weeks," said Don Yeomans of NASA's Near-Earth Object Office at the Jet
Propulsion Laboratory in Pasadena, Calif.

NASA detects and tracks asteroids and comets passing close to Earth
using both ground and space-based telescopes. The Near-Earth Object
Observations Program, commonly called "Spaceguard," discovers these
objects, characterizes a subset of them and plots their orbits to
determine if any could be potentially hazardous to our planet.

JPL manages the Near-Earth Object Program Office for NASA's Science
Mission Directorate in Washington. JPL is a division of the California
Institute of Technology in Pasadena. Cornell University, Ithaca, N.Y.,
operates the Arecibo Observatory under a cooperative agreement with the
National Science Foundation in Arlington, Va.

(NOTE: their server is currently overloaded with requests; this is a "near mirror" of their article until traffic returns to normal levels)

Meteorite “Kosice”, the fall in Slovakia

On February 28th at 22:24:46 UT a bright bolide enlightened the night sky over the Central Europe. Despite the late hour bunch of people were watching Olympics ice hockey finals on TV and eye witnessed astonishing celestial spectacle. The glare of the bolide illuminated streets and interior of apartments, at some places in Eastern Slovakia cannon-like burst or series of low frequency blasts were heard. Due to the bad weather, cloudy skies and scatter showers the Central European Fireball Network (operated by Dr. Pavel Spurny of the Czech Academy of Sciences) did not take direct optical records of the bolide and Slovak Video Network (operated by Dr. Juraj Toth of Comenius University in Bratislava) did not operate that night so that at first moment it seemed that there are no scientific records of this event. Fortunately fast photoelectric sensors on 7 automated fireball stations in the Czech Republic (6) and Austria (1) detected the illumination of the sky caused by the bolide which enabled to determine exact time and duration of the bolide and estimate its brightness. The bolide reached the maximum brightness at least -18 magnitude in one huge flare. In the morning few photographers took a picture of a possible scatter dust trail. Later on several surveillance camera data were published showing the moment when the night became a day for a second but only two videos from Hungary (Orkeny village, Fazzi Daniella and Vass Gabor; Telki village, contact persons Szarneczky Krisztian, Kiss Laszlo) actually captured the fireball itself. Thanks to calibration of videos by several members of the Hungarian Astronomical Association (MCSE - www.mcse.hu) contributed (namely Igaz Antal) and trajectory analysis done by Dr. Jiri Borovicka of the Czech Academy of Sciences gave the hope that significant number of meteorite fragments reached the surface. He also calculated the impact area near town Kosice in Eastern Slovakia. The data from Local Seismic Network Eastern Slovakia (project led by Prof. Moczo of Comenius University) confirmed the fall location as well. The expedition consisting of scientists and graduate students of the Astronomical Institute of the Slovak Academy of Sciences (under the leadership of Jan Svoren), Comenius University in Bratislava (under the leadership of Juraj Toth), Czech Academy of Sciences (under the leadership of Pavel Spurny) started to sweep meadows and forests at the calculated area. The first meteorite was discovered by Juraj Tóth on March 20th. Until the March 28th, 64 meteorite fragments were found. The heaviest fragment weights 2.19 kg, the smallest pieces were only about 0.5 gram. The total mass recovered is equal to 3.917kg. Preliminary analysis implies that the recovered meteorite is classified as an ordinary H5 chondrite (Dr. J. Haloda, Czech Geological Survey). The ongoing data analysis will reveal also other parameters of this bolide as the meteorite atmospheric velocity, pre-atmospheric mass and initial orbit in the Solar System. According to Slovak laws, meteorites belong to the state. Collecting meteorites is allowed only to state or academic institutions from Slovak Republic.

ABSTRACT
Meteorites have traditionally been defined as solid objects that have fallen to Earth from space. This definition, however, is no longer adequate. In recent decades, man-made objects have fallen to Earth from space, meteorites have been identified on the Moon and Mars, and small interplanetary objects have impacted orbiting spacecraft. Taking these facts and other potential complications into consideration, we offer new comprehensive definitions of the terms "meteorite,""meteoroid," and their smaller counterparts:
A meteoroid is a 10-μm to 1-m-size natural solid object moving in interplanetary space. A micrometeoroid is a meteoroid 10 μm to 2 mm in size.
A meteorite is a natural, solid object larger than 10 μm in size, derived from a celestial body, that was transported by natural means from the body on which it formed to a region outside the dominant gravitational influence of that body and that later collided with a natural or artificial body larger than itself (even if it is the same body from which it was launched). Weathering and other secondary processes do not affect an object's status as a meteorite as long as something recognizable remains of its original minerals or structure. An object loses its status as a meteorite if it is incorporated into a larger rock that becomes a meteorite itself.
A micrometeorite is a meteorite between 10 μm and 2 mm in size. Meteorite–"a solid substance or body falling from the high regions of the atmosphere" (Craig 1849); "[a] mass of stone and iron that ha[s] been directly observed to have fallen down to the Earth's surface" (translated from Cohen 1894); "[a] solid bod[y] which came to the earth from space" (Farrington 1915); "A mass of solid matter, too small to be considered an asteroid; either traveling through space as an unattached unit, or having landed on the earth and still retaining its identity" (Nininger 1933); "[a meteoroid] which has reached the surface of the Earth without being vaporized" (1958 International Astronomical Union (IAU) definition, quoted by Millman 1961); "a solid body which has arrived on the Earth from outer space" (Mason 1962); "[a] solid bod[y] which reach[es] the Earth (or the Moon, Mars, etc.) from interplanetary space and [is] large enough to survive passage through the Earth's (or Mars', etc.) atmosphere" (Gomes and Keil 1980); "[a meteoroid] that survive[s] passage through the atmosphere and fall[s] to earth" (Burke 1986); "a recovered fragment of a meteoroid that has survived transit through the earth's atmosphere" (McSween 1987); "[a] solid bod[y] of extraterrestrial material that penetrate[s] the atmosphere and reach[es] the Earth's surface" (Krot et al. 2003).
