Astronomers Monitor Asteroid to Pass Near Mars
50 meters (164 feet) wide that is expected to cross Mars' orbital path early next year. Observations provided by the astronomers and analyzed by 's Near-Earth Object Office at the Jet Propulsion Laboratory in . , indicate the object may pass within 30,000 miles of Mars at about 6 a.m. EST (3 a.m. PST) on Jan. 30, 2008.- Astronomers funded by are monitoring the trajectory of an asteroid estimated to be
"Right now asteroid 2007 WD5 is about half-way between Earth and Mars and closing the distance at a speed of about 27,900 miles per hour," said Don Yeomans, manager of the Near Earth Object Office at JPL. "Over the next five weeks, we hope to gather more information from observatories so we can further refine the asteroid's trajectory."
detects and tracks asteroids and comets passing close to Earth. The Near Earth Object Observation Program, commonly called "Spaceguard," plots the orbits of these objects to determine if any could be potentially hazardous to our planet.
Asteroid 2007 WD5 was first discovered on Nov. 20, 2007, by the NASA-funded Catalina Sky Survey and put on a "watch list" because its orbit passes near Earth. Further observations from both the NASA-funded Spacewatch at Kitt Peak , Ariz. , and the Magdalena Ridge Observatory in gave scientists enough data to determine that the asteroid was not a danger to Earth, but could potentially impact Mars. This makes it a member of an interesting class of small objects that are both near Earth objects and "Mars crossers."
Because of current uncertainties about the asteroid's exact orbit, there is a 1-in-75 chance of 2007 WD5 impacting Mars. If this unlikely event were to occur, it would be somewhere within a broad swath across the planet north of where the Opportunity rover is located.
"We estimate such impacts occur on Mars every thousand years or so," said Steve Chesley, a scientist at JPL. "If 2007 WD5 were to thump Mars on Jan. 30, we calculate it would hit at about 30,000 miles per hour and might create a crater more than half-a-mile wide." The Mars Rover Opportunity is exploring a crater approximately this size right now.
Such a collision could release about three megatons of energy. Scientists believe an event of comparable magnitude occurred here on Earth in 1908 in Tunguska,, but no crater was created. The object was disintegrated by Earth's thicker atmosphere before it hit the ground, although the air blast devastated a large area of unpopulated forest.

What a news TIME magazine named this week MAN OF THE YEAR Im really surprise cuz last year Hugo Chavez won that honor by getting most of the internet vote but the magazine decide to give the honor to the people and internet if I well remember
Well Putin received the honor cuz he made RUSSIA again a key player in this world, made the country 2nd oil producer behind Saudi Arabia, and most of all gave a rebirth to the dying country left behind by the corrupt Yeltsin

this past december 9th marks the beggining of a new era without IMF and World Bank, for Venezuela, Brazil, Ecuador, Bolivia, Paraguay and Argentina, this a new era that those South america countries would help each other with own money and would not ask again for more "expert" advice of IMF that made so great damage to the region.
Venezuela took out more of his money from IMF so that means another crisis for that US Organization that has lost a lot of revenues cuz most of the countries pay their lends

this would be the first time in history that an Empire FALLS because economic problems!!!
Some other big economic group has a mighty GNP bigger than USA, UE no no BRIC (Brazil, Russia, India and China) how about that??

take a look on the article
WASHINGTON, Dec. 3 — A new assessment by American intelligence agencies concludes that Iran halted its nuclear weapons program in 2003 and that the program remains frozen, contradicting judgment two years ago that Tehran was working relentlessly toward building a nuclear bomb.
The conclusions of the new assessment are likely to reshape the final year of the Bush administration, which has made halting Iran’s nuclear program a cornerstone of its foreign policy.
The assessment, a National Intelligence Estimate that represents the consensus view of all 16 American spy agencies, states that Tehran is likely keeping its options open with respect to building a weapon, but that intelligence agencies “do not know whether it currently intends to develop nuclear weapons.”
Iran is continuing to produce enriched uranium, a program that the Tehran government has said is designed for civilian purposes. The new estimate says that enrichment program could still provide Iran with enough raw material to produce a nuclear weapon sometime by the middle of next decade, a timetable essentially unchanged from previous estimates.
But the new estimate declares with “high confidence” that a military-run Iranian program intended to transform that raw material into a nuclear weapon has been shut down since 2003, and also says with high confidence that the halt “was directed primarily in response to increasing international scrutiny and pressure.”
The estimate does not say when American intelligence agencies learned that the weapons program had been halted, but a statement issued by Donald Kerr, the principal director of national intelligence, said the document was being made public “since our understanding of Iran’s capabilities has changed.”
Rather than painting Iran as a rogue, irrational nation determined to join the club of nations with the bomb, the estimate states Iran’s “decisions are guided by a cost-benefit approach rather than a rush to a weapon irrespective of the political, economic and military costs.” The administration called new attention to the threat posed by Iran earlier this year when President Bush had suggested in October that a nuclear-armed Iran could lead to “World War III” and Vice President Dick Cheney promised “serious consequences” if the government in Tehran did not abandon its nuclear program.
Yet at the same time officials were airing these dire warnings about the Iranian threat, analysts at the Central Intelligence Agency were secretly concluding that Iran’s nuclear weapons work halted years ago and that international pressure on the Islamic regime in Tehran was working.
Senator Harry Reid, the majority leader, portrayed the assessment as “directly challenging some of this administration’s alarming rhetoric about the threat posed by Iran.” He said he hoped the administration “appropriately adjusts its rhetoric and policy,” and called for a “a diplomatic surge necessary to effectively address the challenges posed by Iran.”
But the national security adviser, Stephen J. Hadley, quickly issued a statement describing the N.I.E. as containing positive news rather than reflecting intelligence mistakes.
“It confirms that we were right to be worried about Iran seeking to develop nuclear weapons,” Mr. Hadley said. “It tells us that we have made progress in trying to ensure that this does not happen. But the intelligence also tells us that the risk of Iran acquiring a nuclear weapon remains a very serious problem.”
“The estimate offers grounds for hope that the problem can be solved diplomatically — without the use of force — as the administration has been trying to do,” Mr. Hadley said.
The new report comes out just over five years after a deeply flawed N.I.E. concluded that Iraq possessed chemical and biological weapons programs and was determined to restart its nuclear program — an estimate that led to congressional authorization for a military invasion of Iraq, although most of the report’s conclusions turned out to be wrong.
Intelligence officials said that the specter of the botched 2002 N.I.E. hung over their deliberations over the Iran assessment, leading them to treat the document with particular caution.
“We felt that we needed to scrub all the assessments and sources to make sure we weren’t misleading ourselves,” said one senior intelligence official, speaking on condition of anonymity.
