Spacecraft to be controlled by artificial intelligence
It is a concept that had fatal consequences for the astronauts in the science fiction movie 2001: A Space Odyssey after their spaceship’s artificially intelligent computer reasoned it had to kill them in order to continue the mission.
Yet despite this warning from Arthur C Clarke and director Stanley Kubrick, The European Space Agency now hopes to use real-life artificial intelligence to control future spacecraft.
British engineers, supported by ESA, are developing control systems that can be used in satellites, robotic exploration vehicles and spacecraft capable of controlling themselves.
The space vehicles will be able to learn, identify problems, adapt during missions, carry out repairs and take their own decisions about how best to carry out a task.
Details of the research have emerged as ESA prepares to launch the second of its Read more…
Target Earth: Near Earth Asteroids Swarming the February Skies
Photo by Steve E. Farmer Jr.
February 12, another newly discovered hazardous asteroid (PHA) was announced. As most other NEO’s in the past, this one safely passed by Earth…this time.
Potentially Hazardous Asteroid 2011 CU46 was announced on February 12, 2011. This hazardous asteroid did not drift by Earth at only a few thousand miles as in the case of Near Earth Object 2011 CQ1; 2011 CU46 safely passed by at a distance of a little more than 316,000 miles – which is still considered a “near miss” in astronomical terms. PHA 2011 CU46 has a diameter of 20m – 50m; and this particular object would likely cause a massive fireball and surface damage if it were to impact Earth in a populated area.
Potentially Hazardous Asteroids & Near Earth Objects
As defined by NASA, A Potentially Hazardous Asteroid (PHA) is based on parameters that measure the asteroid’s potential to make threatening close approaches to the Earth. An asteroid which comes within an orbital intersection distance of 0.05 AU with Earths orbit and is of a diameter of 110m – 240m, is normally identified as a potentially hazardous object. Other factors are also included.
Since the February 4 announcement of NEO 2011 CQ1, over forty more Near Earth Objects have been discovered, identified, and catalogued.
Apophis Likely to Miss, What about PHA 2011 AG5?
PHA 2011 AG5 was discovered by Mt. Lemmon Survey on January 8, 2011. After more than one-hundred extra observations of this Potentially Hazardous Asteroid were collected by both amateur and professional astronomers, orbital elements were calculated and it was determined that 2011 AG5 could possibly impact Earth in the year 2052. More observations and research is needed to refine the orbit of this asteroid.
2011 AG5 is very similar to the famous asteroid Apophis which could possibly impact the Earth in the year 2036. Apophis is a little larger in diameter that 2011 AG5 and is expected to pass by Earth twice as close as 2011 AG5. Both of these minor planets are large enough to cause substantial damage to a major city on Earth if impact were to occur, but with any luck these minor planets will spare Earth and safely pass us by.
Preparing for Asteroid Impact
It’s only a matter of time before the announcement comes that Earth will obtain an impact from a minor planet large enough to cause wide-spread damage. It is this reason why more studies be performed on minor planets – to help further improve our understandings on these objects in hopes to give us a better defense option when that announcement comes. We have the technology to detect these hazardous objects and certain programs are working on methods to deflect or destroy asteroids. With any luck, they will design a fail-proof method to eliminate the potential risk from these objects impacting Earth.
The supply of corn keeps getting smaller
675 million bushels of corn may seem like a lot, but that is only an 18 day supply for the US grain market, and that is the reason corn prices pushed above $7 Wednesday on the CME. March corn did not close above that level, but settled at $6.98 per bushel following USDA’s February Supply and Demand report that indicated the ethanol industry was refining corn faster than previously thought.
Corn, beans and wheat prices have all been rising, but so has the price for ethanol. A year ago, ethanol was in the $1.70 per gallon range, but Wednesday closed at $2.457 per gallon, the highest it has been since the early summer price spike in 2008 when it exceeded $2.80 per gallon.
The result of the ethanol industry’s demand for corn tightens down the supply, says University of Missouri marketing specialist Melvin Brees. In his Crop Report Commentary Brees says USDA economists raised corn use by 70 million bushels and 50 million of that was added to Read more…
Gaddafi tells Palestinians: revolt against Israel
Ali Shuaib and Salah Sarrar
TRIPOLI (Reuters) – Palestinian refugees should capitalize on the wave of popular revolts in the Middle East by massing peacefully on the borders of Israel until it gives in to their demands, Libyan leader Muammar Gaddafi said on Sunday.
Gaddafi is respected in many parts of the Arab world for his uncompromising criticism of Israel and Arab leaders who have dealings with the Jewish state, though some people in the region dismiss his initiatives as unrealistic.
He was giving his first major speech since a popular uprising in neighboring Egypt forced President Hosni Mubarak to resign, an event which electrified the Arab world and prompted speculation that other Arab governments could also be toppled.
“Fleets of boats should take Palestinians … and wait by the Palestinian shores until the problem is resolved,” Gaddafi was shown saying on state television. “This is a time of popular revolutions.”

Chile: fifth earthquake in three days

A MAGNITUDE 5.6 earthquake struck Chile – the third to hit within hours and the fifth tremor in three days.
The latest tremor hit 41 kilometres northwest of the central city of Concepcion at a depth of 17.7 kilometres. The quakes earlier in the day measured 6.0 and 5.8.
On Friday two quakes – measuring 6.3 and a 6.8 – rattled the region.
All the tremors have occurred in the same area heavily damaged by an 8.8 magnitude quake nearly a year ago.
That disaster resulted in more than 500 deaths and $30 billion in damage, and led to an inquiry over the lack of a timely tsunami warning.
2012: Leaks In Earth’s Magnetic Field Found
Scientists have found two large leaks in Earth’s magnetosphere, the region around our planet that shields us from severe solar storms.
The leaks are defying many of scientists’ previous ideas on how the interaction between Earth’s magnetosphere and solar wind occurs: The leaks are in an unexpected location, let in solar particles in faster than expected and the whole interaction works in a manner that is completely the opposite of what scientists had thought.

Egypt’s military leaders dissolved parliament and suspended the constitution on Sunday, meeting two key demands of protesters who have been keeping up pressure for immediate steps to push forward the transition to democratic, civilian rule after forcing Hosni Mubarak out of power.
In their latest communique, the military rulers that took over when Mubarak stepped down Friday, said they will run the country for six months, or until presidential and parliament elections can be held.
The military leaders said they were forming a committee to amend the constitution and set the rules for popular referendum to endorse the amendments.
Both the lower and upper houses of parliament are being dissolved. The last parliamentary elections in November and December were Read more…
S. Korea confirms 2 more bird flu outbreaks
SEOUL, Feb. 13 (Yonhap) — South Korea on Sunday confirmed two additional bird flu outbreaks in areas near Seoul despite nationwide efforts to stem the spread of the disease.
The farm ministry said the new cases were reported at a medium-sized duck farm and a small poultry farm that raises chickens and ducks, which reported symptoms earlier in the week.
All 8,400 birds on the two farms in Hwaseong south of Seoul and Dongducheon north of the capital have been culled and buried, with other bird farms within a 3-kilometer radius being checked for infections.
The outbreaks are the Read more…

China sees U.S. stoking Brazil and India anger over yuan
By Zhou Xin and Koh Gui Qing
BEIJING (Reuters) – The United States has incited Brazil and India to criticize China’s currency policy, but Beijing need not worry too much because it can defuse the tension through talks, a series of Chinese government advisers told Reuters.
Independent analysts warned, however, that a belief that Brazil and India are doing Washington’s bidding and are not truly aggrieved could make Beijing complacent and undermine fledgling ties between the emerging powers.
Increasingly widespread calls for a stronger yuan are awkward for China, which is accustomed to facing U.S. pressure over its tightly controlled exchange rate but has long tried to cast itself as the natural ally of other developing nations.
Brazil and India are unlikely to be any more successful than the United States in persuading Beijing to permit faster appreciation, researchers in Chinese government think tanks said.
“They must realize that the root of problem is not China but Read more…
