Meteorite mineral made in the lab
By Victoria Gill Science reporter, BBC News |
The team use large projectile launchers to create shock waves |
By slamming materials together, scientists have made a mineral that is found naturally only in meteorites and the deep layers of Earth's mantle.
Their successful "shock" experiment reveals new clues about the formation of our early Solar System.
The team report the production of the mineral wadsleyite in the journal PNAS.
Its creation in the lab shows that objects that collided to form the planets may have been far smaller than previously thought. ...

Meteor/Meteorite News- Tektites Sent Flying 11AUG09
Planet Smash-Up Sends Vaporized Rock, Hot Lava Flying
Jet Propulsion Laboratory
August 10, 2009
http://www.jpl.nasa.gov/news/news.cfm?release=2009-119
PASADENA, Calif. -- NASA's Spitzer Space Telescope has found evidence of
a high-speed collision between two burgeoning planets around a young star.
Astronomers say that two rocky bodies, one as least as big as our moon
and the other at least as big as Mercury, slammed into each other within
the last few thousand years or so -- not long ago by cosmic standards.
The impact destroyed the smaller body, vaporizing huge amounts of rock
and flinging massive plumes of hot lava into space. An artist's
animation of the event is at
http://www.nasa.gov/mission_pages/spitzer/multimedia/spitzer-20090810.html
.
Spitzer's infrared detectors were able to pick up the signatures of the
vaporized rock, along with pieces of refrozen lava, called tektites.
"This collision had to be huge and incredibly high-speed for rock to
have been vaporized and melted," said Carey M. Lisse of the Johns
Hopkins University Applied Physics Laboratory, Laurel, Md., lead author
of a new paper describing the findings in the Aug. 20 issue of the
Astrophysical Journal. "This is a really rare and short-lived event,
critical in the formation of Earth-like planets and moons. We're lucky
to have witnessed one not long after it happened."
Lisse and his colleagues say the cosmic crash is similar to the one that
formed our moon more than 4 billion years ago, when a body the size of
Mars rammed into Earth.
"The collision that formed our moon would have been tremendous, enough
to melt the surface of Earth," said co-author Geoff Bryden of NASA's Jet
Propulsion Laboratory, Pasadena, Calif. "Debris from the collision most
likely settled into a disk around Earth that eventually coalesced to
make the moon. This is about the same scale of impact we're seeing with
Spitzer -- we don't know if a moon will form or not, but we know a large
rocky body's surface was red hot, warped and melted."
Our solar system's early history is rich with similar tales of
destruction. Giant impacts are thought to have stripped Mercury of its
outer crust, tipped Uranus on its side and spun Venus backward, to name
a few examples. Such violence is a routine aspect of planet building.
Rocky planets form and grow in size by colliding and sticking together,
merging their cores and shedding some of their surfaces. Though things
have settled down in our solar system today, impacts still occur, as was
observed last month after a small space object crashed into Jupiter.
Lisse and his team observed a star called HD 172555, which is about 12
million years old and located about 100 light-years away in the far
southern constellation Pavo, or the Peacock (for comparison, our solar
system is 4.5 billion years old). The astronomers used an instrument on
Spitzer, called a spectrograph, to break apart the star's light and look
for fingerprints of chemicals, in what is called a spectrum. What they
found was very strange. "I had never seen anything like this before,"
said Lisse. "The spectrum was very unusual."
After careful analysis, the researchers identified lots of amorphous
silica, or essentially melted glass. Silica can be found on Earth in
obsidian rocks and tektites. Obsidian is black, shiny volcanic glass.
Tektites are hardened chunks of lava that are thought to form when
meteorites hit Earth.
Large quantities of orbiting silicon monoxide gas were also detected,
created when much of the rock was vaporized. In addition, the
astronomers found rocky rubble that was probably flung out from the
planetary wreck.
The mass of the dust and gas observed suggests the combined mass of the
two charging bodies was more than twice that of our moon.
Their speed must have been tremendous as well -- the two bodies would
have to have been traveling at a velocity relative to each other of at
least 10 kilometers per second (about 22,400 miles per hour) before the
collision.
Spitzer has witnessed the dusty aftermath of large asteroidal impacts
before, but did not find evidence for the same type of violence --
melted and vaporized rock sprayed everywhere. Instead, large amounts of
dust, gravel, and boulder-sized rubble were observed, indicating the
collisions might have been slower-paced. "Almost all large impacts are
like stately, slow-moving Titanic-versus-the-iceberg collisions, whereas
this one must have been a huge fiery blast, over in the blink of an eye
and full of fury," said Lisse.

EARTH ASTEROID NEWS- ASTEROID 1994CC TRIPLE THE BANG 8AUG09
http://www.jpl.nasa.gov/news/features.cfm?feature=2259
Triple Asteroid System Triples Observers' Interest
Jet Propulsion Laboratory
August 06, 2009
Radar imaging at NASA's Goldstone Solar System Radar on June 12
and 14, 2009, revealed that near-Earth asteroid 1994 CC is a triple
system. Asteroid 1994 CC encountered Earth within 2.52 million
kilometers (1.56 million miles) on June 10. Prior to the flyby,
very little was known about this celestial body. 1994 CC is only
the second triple system known in the near-Earth population. A
team led by Marina Brozovic and Lance Benner, both scientists at
NASA's Jet Propulsion Laboratory in Pasadena, Calif., made the
discovery.
1994 CC consists of a central object about 700 meters (2,300 feet)
in diameter that has two smaller moons revolving around it.
Preliminary analysis suggests that the two small satellites are at
least 50 meters (164 feet) in diameter. Radar observations at
Arecibo Observatory in Puerto Rico, led by the center's director
Mike Nolan, also detected all three objects, and the combined
observations from Goldstone and Arecibo will be utilized by JPL
scientists and their colleagues to study 1994 CC's orbital and
physical properties.
The next comparable Earth flyby for asteroid 1994 CC will occur
in the year 2074 when the space rock trio flies past Earth at a
distance of two-and-a-half million kilometers (1.6 million miles).
Of the hundreds of near-Earth asteroids observed by radar, only
about 1 percent are triple systems.

PERSEIDS METEOR OUTBURST - iPHONE GETS INVOLVED 5AUG09
Space Weather News for Aug. 4, 2009
http://spaceweather.com
POSSIBLE PERSEID METEOR OUTBURST: This year's Perseid meteor
shower could be even better than usual. According to NASA's
Meteoroid Environment Office, a filament of comet dust has
drifted across Earth's path and when Earth passes through it,
sometime between 0800 and 0900 UT (1 - 2 am PDT) on
August 12th, the Perseid meteor rate could surge to twice
its normal value. Check http://spaceweather.com
and observing tips.
PERSEIDS ON YOUR iPHONE: Spaceweather.com is pleased to
announce a new iPhone/iPod application dedicated to the
upcoming Perseid meteor shower. It features a Perseid
countdown clock, news alerts, an easy-to-use sky map, and a
live gallery of photos from around the world. Sky watchers
of all types will find it a valuable companion when the
shower peaks later this month.
