Iridium Satellite Space Crash May Produce Future Meteors? 11FEB09


Debris Spews Into Space in Collision of Satellites
By WILLIAM J. BROAD
Published: February 11, 2009
For decades, space experts have warned of orbits around the planet growing so crowded that two satellites might one day slam into one another, producing swarms of treacherous debris. It happened Tuesday. And the whirling fragments could pose a threat to the International Space Station, orbiting 215 miles up with three astronauts onboard, though officials said the risk was now small. “This is a first, unfortunately,” Nicholas L. Johnson, chief scientist for orbital debris at the National Aeronautics and Space Administration, said of the collision. It happened some 490 miles above northern Siberia, at around noon Eastern time. Two communications satellites — one Russian, one American — cracked up in silent destruction. In the aftermath, military radars on the ground tracked large amounts of debris going into higher and lower orbits. “Nothing to this extent” has ever happened before, Mr. Johnson said. “We’ve had three other accidental collisions between what we call catalog objects, but theywere all much smaller than this,” the objects always very small and moderate insize.The communication satellites, he added, “are two relatively big objects. ”The American satellite was an Iridium, one of a constellation of 66 space craft. Liz DeCastro, corporate communications director of Iridium Satellite, based in Bethesda, Md., said that the satellite weighed about 1,200 pounds and that itsbody was more than 12 feet long, not including large solar arrays.In a statement, the company said that it had “lost an operational satellite” on Tuesday, apparently after it collided with “a nonoperational” Russian satellite. “Although this event has minimal impact on Iridium’s service,” the statement added, “the company is taking immediate action to address the loss. ” The company’s hand-held phones can be used anywhere around the globe to give users voice and data communications. Mr. Johnson said the Russian satellite was presumably nonfunctional. Officials at the Russian Embassy in Washington could not be reached for comment. Mr. Johnson said the United States military’s tracking radars had yet to determine the number of detectable fragments. “It’s going to take a while,” he said. “It’s very, very difficult to discriminate all those objects when they’re really close together. And so over the next couple of days we’ll have a much better understanding.”At a minimum, Mr. Johnson added, “I think we’re talking many, many dozens, if not hundreds.” The debris could threaten the space station and its astronaut crew, he said. “There are actually debris from this event which we believe are going through space station altitude already,” he said. The risk to the station, Mr. Johnson added, “is going to be very, very small.” In the worst case, he said, “We’ll just dodge them if we have to. It’s the small things you can’t see that are the ones that can do you harm. ”In Houston, International Space Station controllers have often adjusted its orbit to get out of the way of speeding space debris, which can move so incredibly fast that even small pieces pack a destructive wallop. John Yembrick, a NASA spokesman in Washington, said the agency now judged therisk of collision with the speeding fragments to be “very small.” The threat, headded, is defined and acceptable. Mr. Johnson, who works at the Johnson Space Center in Houston, said the new swarms of whirling debris might also eventually pose a threat to other satellites in an orbital chain reaction. “What we’re doing now is trying to quantify that risk,” he said. “That’s a workin progress. It’s only been 24 hours. We put first things first,” meaning the station and preparing for the next shuttle mission.

Comet Lulin-Green Comet Approaches Earth 4FEB09

Green Comet Approaches Earth
NASA Science news02.04.2009 February 4, 2009:

In 1996, a 7-year-old boy in China bent over the eyepiece of a small telescope and saw something that would change his life--a comet of flamboyant beauty, bright and puffy with an activetail. At first he thought he himself had discovered it, but no, helearned, two men named "Hale" and "Bopp" had beat him to it. Mastering his disappointment, young Quanzhi Ye resolved to find his own comet one day.And one day, he did. Fast forward to a summer afternoon in July 2007. Ye, now 19 years old and a student of meteorology at China's Sun Yat-sen University, bent over his desk to stare at a black-and-white star field. The photo was taken nights before by Taiwanese astronomer Chi Sheng Lin on "skypatrol" at the Lulin Observatory. Ye's finger moved from point to point--and stopped. One of the stars was not a star, it was a comet, and this time Ye saw it first.Comet Lulin, named after the observatory in Taiwan where the discovery-photo was taken, is now approaching Earth. "It is a green beauty that could become visible to the naked eye any day now," says Ye. Amateur astronomer Jack Newton sends this photo from his backyard observatory in Arizona: http://science.nasa.gov/headlines/y2009/images/greencomet/Jack-Newton1.jpg

"My retired eyes still cannot see the brightening comet," says Newton,"but my 14-inch telescope picked it up quite nicely on Feb. 1st."The comet makes its closest approach to Earth (0.41 AU) on Feb. 24,2009. Current estimates peg the maximum brightness at 4th or 5th magnitude, which means dark country skies would be required to see it.No one can say for sure, however, because this appears to be Lulin's first visit to the inner solar system and its first exposure to intense sunlight. Surprises are possible.Lulin's green color comes from the gases that make up its Jupiter-sized atmosphere. Jets spewing from the comet's nucleus contain cyanogen (CN:a poisonous gas found in many comets) and diatomic carbon (C2). Both substances glow green when illuminated by sunlight in the near-vacuum ofspace.In 1910, many people panicked when astronomers revealed Earth would passthrough the cyanogen-rich tail of Comet Halley. False alarm: The wispy tail of the comet couldn't penetrate Earth's dense atmosphere; even it if had penetrated, there wasn't enough cyanogen to cause real trouble. Comet Lulin will cause even less trouble than Halley did. At closest approach in late February, Lulin will stop 38 million miles short of Earth, utterly harmless.To see Comet Lulin with your own eyes, set your alarm for 3 am. The comet rises a few hours before the sun and may be found about 1/3rd of the way up the southern sky before dawn. Here are some dates when it is especially easy to find:
sky map

Feb. 6th:
Comet Lulin glides by Zubenelgenubi, a double star at the fulcrum of Libra's scales. Zubenelgenubi is not only fun to say (zuBEN-el-JA-newbee), but also a handy guide. You can see Zubenelgenubi with your unaided eye (it is about as bright as stars in the Big Dipper); binoculars pointed at the binary star reveal Comet Lulin in beautiful proximity.
[sky map]

Feb. 16th:
Comet Lulin passes Spica in the constellation Virgo. Spica is a star of first magnitude and a guidepost even city astronomers cannotmiss. A finderscope pointed at Spica will capture Comet Lulin in the field of view, centering the optics within a nudge of both objects. [skymap ]

Feb. 24th:
Closest approach! On this special morning, Lulin will lie just a few degrees from Saturn in the constellation Leo. Saturn is obvious to the unaided eye, and Lulin could be as well. If this doesn't draw you out of bed, nothing will.
[sky map]

Ye notes that Comet Lulin is remarkable not only for its rare beauty,but also for its rare manner of discovery. "This is a 'comet ofcollaboration' between Taiwanese and Chinese astronomers," he says. "The discovery could not have been made without a contribution from both sides of the Strait that separates our countries. Chi Sheng Lin andother members of the Lulin Observatory staff enabled me to get the images I wanted, while I analyzed the data and found the comet."Somewhere this month, Ye imagines, another youngster will bend over an eyepiece, see Comet Lulin, and feel the same thrill he did gazing at Comet Hale-Bopp in 1996. And who knows where that might lead...?"I hope that my experience might inspire other young people to pursue the same starry dreams as myself," says Ye.

Sugar compounds found in meteorites; bolsters theory that ingredients of life came from outer space
Author: ALEX DOMINGUEZ Associated Press Writer Date: December 19, 2001 Publication: Associated Press Archive Sugar compounds, an indispensable ingredient for life today, have been found in meteorites, bolstering the theory that chunks of rock from outer space delivered the materials that gave rise to life in Earth. Another key ingredient, amino acids, has already been found in meteorites. George Cooper of NASA's Ames Research Center at Moffett Field, Calif., said that while it has not been proved that meteorites delivered the materials that led to life, the discovery means...

Researchers says NASA's Mars researchers have failed to prove case for bacteria fossils in Martian meteorite
Author: PAUL RECER AP Science Writer Date: November 20, 2001 Publication: Associated Press Archive A group of researchers say NASA scientists have failed to prove their contention that a Mars meteorite contains evidence of ancient microbial life on the Red Planet. A group led by Peter R. Buseck of Arizona State University said that the NASA researchers have inadequate evidence showing that tiny crystalline structures in Mars meteorite ALH84001 were formed by bacteria billions of years ago as the rock was sitting on the Martian surface. A study with Buseck as the first author appears... Click here for complete article ($1.50)

Asteroid photos show complex surface with dust 'ponds' likely formed after impacts, researchers say
Author: WILLIAM McCALL Associated Press Writer Date: September 26, 2001 Publication: Associated Press Archive Photos taken by the first spacecraft to land on an asteroid show a landscape littered with boulders, small rocks and other debris that appear to have partly eroded and settled into mysterious "ponds" of thick dust, researchers say. The photos taken by the Near Earth Asteroid Rendezvous spacecraft, called NEAR, add evidence to the theory that even the weak gravity of an asteroid can hold on to much of the flying debris created when struck by another object such as...

Study: Crystal in meteorite proves life once existed on Mars
Author: PAUL RECER AP Science Writer Date: February 27, 2001 Publication: Associated Press Archive
A crystal found in a meteorite from Mars could only have been formed by a microbe and may be evidence of the oldest life form ever found, researchers say.
Scientists at the Johnson Space Center in Houston say that a crystalized magnetic mineral, called magnetite, found in a Martian meteorite is similar to crystals formed on Earth by bacteria. "I am convinced that this is supporting evidence for the presence of ancient life on Mars," said Kathie Thomas-Keprta, an...
