Some atmospheric and magnetospheric effects possibly related to the Vitim bolide impact
E.A. Kasatkina and O.I. Shumilov
Institute of North Industrial Ecology Problems, Kola Science Centre RAS, 184209 Apatity,
Russia

Sensors aboard US Department of Defence satellites detected the impact of a bolide
on 24 September 2002 at 16:49 UT. The bolide had disappeared at an altitude of
30 km above the Vitim river, Siberia (58.21N, 113.46E). The total radiated energy
was 8.6x10ˆ11 Joules. An unusual infrasonic event with a 30-minute duration has
been detected by the Apatity infrasonic array at Kola Peninsula (67.3N, 33.3E) on
September 24, 2002 at 22:20 UT. The infrasonic signal had been detected by three
spatially separated microbarographs operating in the passband from 0.0001 to 1 Hertz
at a distance of 4000 km from the source. Estimates of the local infrasound velocity
and the direction of the signal arrival seem to be in agreement with the acoustic travel
velocity and the source azimuth. We cannot exclude that the Vitim bolide (or minicomet)
effects were as well appeared at some other atmospheric and magnetospheric
phenomena, e.g. in magnetic disturbances at high latitude stations, cosmic radionoise
absorption, variations of air conductivity. These effects are compared with some other
similar effects related to different bolides like Tunguska and Brasilian ones. A possible
nature of the effects is discussed.

Tunguska 101th anniversary 30JUN09
Tomorrow, Tuesday June 30, 2009 marks the one-hundred-first anniversary of the Tunguska impact event in Russia of June 30, 1908. Wikipedia has a very good report on Tunguska:
... At around 7:17 a.m. local time, Tungus natives and Russian settlers in the hills northwest of Lake Baikal observed a column of bluish light, nearly as bright as the Sun, moving across the sky. About 10 minutes later, there was a flash and a sound similar to artillery fire. Eyewitnesses closer to the explosion reported the sound source moving east to north. The sounds were accompanied by a shock wave that knocked people off their feet and broke windows hundreds of miles away. The majority of eyewitnesses reported only the sounds and the tremors, and not the sighting of the explosion. Eyewitness accounts differ as to the sequence of events and their overall duration. ...

Spider Crater, Western Australia

download large image (6 MB, JPEG)

Over the Kimberley Region of northern Western Australia, satellite sensors and airplane passengers alike can see a giant arachnid sprawling over the arid landscape. This spider’s not just big, it’s old. This prehistoric monster crawls out of the past as if to remind us of the destructive power of the cosmos.

The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on NASA’s Terra satellite captured this image of Spider Crater and its surroundings on August 11, 2000. In this false-color image, the arid landscape appears in varying shades of crimson. Water appears blue-black, namely in the meandering river near the bottom edge of the image. Vegetation appears in shades of red. While vegetation looks sparse throughout the area, the intense red dots along the river indicate fairly lush—if intermittent—vegetation lining the riverbanks.

Near the center of the image is the Spider, sunlight giving an oddly ghostlike appearance to the steep ridges that form its legs. Geologists long puzzled over what this structure was, but found an important clue in the 1970s. They found shatter cones—cone-shaped, grooved rocks known only to appear in craters left by meteor or asteroid impacts. Other clues to the structure’s origin appeared in the form of strongly deformed layers of sedimentary rock that showed evidence of extraterrestrial trauma.

Spider Crater rests in a depression some 13 by 11 kilometers (8 by 7 miles) across. Meteorite craters often have central areas of uplift, and Spider Crater fits this pattern, with a central dome roughly 500 meters (1,640 feet) in diameter. Radiating from this central dome are features unusual in impact craters in general, but important in giving this crater its nickname. Overlapping beds of tough sandstone that have weathered the elements far better than the surrounding rocks form the spider’s “legs.” So while Spider Crater sits in a depression and has a central uplift area characteristic of impact craters, it shows extreme differences in erosion, giving it a unique appearance.

The age of Spider Crater is uncertain, but its formation has been estimated to fall between 900 and 600 million years ago. If this age estimate is correct, the crater formed from an impact that occurred during the Neoproterozoic, a period of geologic history when, some geologists hypothesize, Earth underwent a series of global ice ages nicknamed “Snowball Earth.”

NASA GIVES MEDIA, PUBLIC LOOK INSIDE APOLLO MOON ROCK VAULT

HOUSTON -- NASA will offer reporters an unprecedented chance to
conduct interviews with scientists inside the lab that stores moon
rocks Apollo astronauts collected during their six missions. The July
2 interview opportunities from the Apollo Lunar Sample Processing Lab
and Storage Vaults at NASA's Johnson Space Center in Houston will
take place nearly 40 years after humans first walked on the moon.

Using the NASA Television's Live Interview Media Outlet satellite
channel, news organizations will have a chance to talk with
scientists who study the lunar samples. The interviews will originate
from inside the lunar sample vault, amid the trays of moon rocks and
soil samples. Among the samples are those Apollo 11 astronauts Neil
Armstrong and Buzz Aldrin brought back to Earth in July 1969.

Live interview opportunities will be available from 6 a.m. to 8 a.m.
and 2 p.m. to 4 p.m. CDT with lunar sample scientists Gary Lofgren
and Andrea Mosie. Lofgren is the lunar curator at Johnson and has
been with the lab since the Apollo era. Mosie has been a scientist in
the current lab since it opened in 1979.

To participate in the interviews, journalists should contact Victor
Scott at 281-483-4942 or victor.j.scott@nasa.gov no later than noon,
July 1.

The public also will have an opportunity to take a virtual tour of the
lunar sample lab and ask the scientists questions via Ustream and
Twitter from 12 p.m. to 1 p.m. The public can submit questions to
Johnson's Twitter account, @NASA_Johnson, beginning today and via
Ustream live during the event. The tour and the question-and-answer
session also will be broadcast live on NASA TV.

To view the live broadcast on Ustream and submit questions, visit:

http://www.ustream.tv/channel/nasa-live

Between 1969 and 1972, six Apollo spaceflight missions brought back
842 pounds and 22,000 separate samples of lunar rocks, core samples,
pebbles, sand and dust from the lunar surface. The majority of the
samples are stored at the Apollo Lunar Sample Processing Lab and
Storage Vaults at Johnson, with a small subset held at the White
Sands Space Harbor in New Mexico. The samples continue to be studied
by scientists around the world. The work has provided invaluable
knowledge as NASA prepares to return to the moon.

The NASA Live Interview Media Outlet satellite channel will be used
for the event. The channel is a digital satellite C-band downlink by
uplink provider Americom. It is on satellite AMC 6, transponder 5C,
located at 72 degrees west, downlink frequency 3785.5 Mhz based on a
standard C-band 5150 Mhz L.O., vertical polarity, FEC is 3/4, data
rate is 6.00 Mhz, symbol rate is 4.3404 Mbaud, transmission DVB,
minimum Eb/N0 is 6.0 dB. For NASA TV streaming video, downlink and
schedule information, visit:

NASA is planning a number of activities and events in 2009 as the 40th
anniversary of the first moon landing on July 20 approaches. The
events will celebrate the Apollo Program, its accomplishments, and
the benefits to our lives today. For more information, visit:

The Complicated Geologic History of Asteroid 4 Vesta

--- Meteorites from asteroid 4 Vesta show that it contains patches of granite-like rock.

Written by G. Jeffrey Taylor
Hawai‘i Institute of Geophysics and Planetology

Planetary scientists are pretty sure that almost all of the HED meteorites come from the fourth-largest asteroid, 4 Vesta. HED stands for the three types of rocks that make up the group. As cosmochemists have studied the meteorites over the years, their view of the geologic history of the asteroid has become progressively more complicated. Jean-Alix Barrat and Marcel Bohn (CNRS and University of Brest, France), Philippe Gillet (CNRS and Ecole Normale Supérieure de Lyon, France), and Akira Yamaguchi (National Institute of Polar Research, Tokyo, Japan) have found that Vesta is even more complicated--and interesting--than we thought. ...

Chicora Meteor

On June 24, 1938 a meteorite fell in the vicinity of Chicora,Pennsylvania. Named the "Chicora Meteor", the 450+ tonne meteor exploded approximately twelve miles above the Earth's surface. Only two fragments of the meteorite were found following initial investigations. They had masses 242g and 61g, and were discovered some miles short of the calculated point of impact of the main mass - which is yet to be found. Two more small fragments were found nearby in 1940.
Numerous reports of the Chicora Meteor mention that a cow was struck and injured by a falling stone; other accounts say that the cow was in fact killed by the stone.
The meteor was an olivine-hypersthene chondrite. Its remains were split between the Carnegie Museum of Natural History and the Smithsonian Institution.
The sound and light of the exploding meteor were initially mistaken for an explosion in the powder magazine at West Winfield, and was compared by investigators FW Preston, EP Henderson and James R Randolph as comparable to with the Halifax explosion of 1917 in destructive power. "If it had landed on Pittsburgh there would have been few survivors", they stated.^[3]
