France launches air strike in Mali

PARIS/BAMAKO (Reuters) - The French air force carried out an air strike in Mali on Friday in support of government forces trying to push back Islamist rebels, French Foreign Minister Laurent Fabius said.

The raid came as France launched a military intervention in the west African state to help the government resist a push south by rebel forces.

Western powers fear the alliance of al Qaeda-linked militants that seized the northern two-thirds of Mali in April will seek to use the vast desert zone as a launchpad for international attacks.

"French forces brought their support this afternoon to Malian army units to fight against terrorist elements," French President Francois Hollande told reporters. "This operation will last as long as is necessary."

Hollande said United Nations Security Council resolutions meant France was acting in accordance with international laws.

Earlier, Hollande had made it clear that France would intervene to stop any further drive southward by Islamist rebels as Malian soldiers launched a counter-offensive to wrest back a town captured by militants this week.

Mali's government appealed for urgent military aid from France on Thursday after Islamist fighters encroached further south, seizing the town of Konna in the center of the country. The rebel advance caused panic among residents in the nearby towns of Mopti and Sevare, home to a military base and airport.

"We are faced with blatant aggression that is threatening Mali's very existence. France cannot accept this," Hollande said in a New Year speech to diplomats and journalists. "We will be ready to stop the terrorists' offensive if it continues."

The U.N. Security Council in December authorized the deployment of an African-led force supported by European states.

"The French believe that France, and Europe, face a real security threat from what is happening in the Sahel," said Jakkie Cilliers, executive director of the Institute for Security Studies in South Africa.

More than two decades worth of peaceful elections had earned the Mali a reputation as a bulwark of democracy in a part of Africa better known for turmoil - an image that unraveled in a matter of weeks after a coup last March that paved the way for the Islamist rebellion.

Mali is Africa's third largest gold producer and a major cotton grower, and home to the fabled northern desert city of Timbuktu - an ancient trading hub and UNESCO World Heritage site that hosted annual music festivals before the rebellion.

REINFORCEMENTS ARRIVE

Residents had seen Western soldiers arriving late on Thursday at an airport at Sevare, 60 km (40 miles) south of Konna.

Sevare residents also reported the arrival of military helicopters and army reinforcements, which took part in the counter-attack to retake Konna overnight on Thursday in a bid to roll back the militant's southward drive.

"Helicopters have bombarded rebel positions. The operation will continue," a senior military source in Bamako said.

A source at Sevare airport also said around a dozen war planes had arrived on Friday. A spokesman for the Nigerian air force said planes had been deployed to Mali for a reconnaissance mission, not for combat.

A spokesman one of the main groups in the Islamist rebel alliance said they remained in control of Konna.

Asked whether the rebels intended to press ahead to capture Sevare and Mopti, the Ansar Dine spokesman, Sanda Ould Boumama, said: "We will make that clear in the coming days." He said any intervention by France would be evidence of an anti-Islam bias.

The French foreign ministry stepped up its security alert on Mali and parts of neighboring Mauritania and Niger on Friday, extending its red alert - the highest level - to include Bamako. France has 8 nationals in Islamist hands in the Sahara after a string of kidnappings.

"Due to the serious deterioration in the security situation in Mali, the threat of attack or abduction is growing," the ministry said in its travel alert. "It is strongly recommended that people avoid unnecessarily exposing themselves to risks."

Wall Street climbs on China data; S&P nears resistance

NEW YORK (Reuters) - Stocks climbed on Thursday on optimism about global growth spurred by stronger-than-expected exports in China, the world's second-biggest economy, though gains in the S&P 500 were capped at a resistance level near a 5-year high.

Financial and energy stocks were the day's top gainers in afternoon trading. The financial sector index <.gspf> rose 0.8 percent and the energy sector <.gspe> was up 0.6 percent.

The benchmark Standard & Poor's 500 index hovered near a five-year closing peak of 1,466.47. On Friday, the index had closed at its highest since December 2007.

"The market is technically right at the level of resistance, near 1,465-1,467," said Randy Frederick, managing director of active trading and derivatives at Charles Schwab.

"A solid breakthrough above the level would be the start of a next leg higher, but it looks like it is going to be difficult to break above that level for now," Frederick said, citing concerns about the corporate earnings season and impending negotiations over the U.S. debt ceiling.

By late morning, the S&P 500 had erased almost all its gains from earlier Thursday in minutes. Some traders said the dip was triggered by a trade in the options market that prompted a large amount of S&P futures to hit the market at the same time, sending the S&P 500 index down rapidly.

Data showed China's export growth rebounded sharply to a seven-month high in December, a strong finish to the year after seven straight quarters of slowdown.

The Dow Jones industrial average <.dji> was up 36.20 points, or 0.27 percent, at 13,426.71. The Standard & Poor's 500 Index <.spx> was up 5.11 points, or 0.35 percent, at 1,466.13. The Nasdaq Composite Index <.ixic> was up 0.05 points, or 0.00 percent, at 3,105.86.

In company news, shares of upscale jeweler Tiffany dropped 4.3 percent to $60.53 after it said earnings for the year through January 31 will be at the lower end of its forecast.

U.S.-traded Nokia shares jumped 18 percent to $4.42 after the Finnish handset maker said its fourth-quarter results were better than expected and that the mobile phone business achieved underlying profitability.

Herbalife Ltd stepped up its defense against activist investor Bill Ackman, stressing it was a legitimate company with a mission to improve nutrition and help public health. The stock was down 2.4 percent at $39.15.

U.S. data showed claims for unemployment benefits rose last week, though seasonal volatility made it difficult to get a clear picture of the labor market's health.

Also, U.S. wholesale inventories rose more than expected in November and sales rose by the most in more than 1-1/2 years. The market's reaction to both reports was muted.

Jaguars fire Mularkey after team's worst season

JACKSONVILLE, Fla. (AP) — The Jacksonville Jaguars fired coach Mike Mularkey on Thursday after just one season, the worst in franchise history.

New general manager David Caldwell made the announcement two days after he was hired, giving him a clean slate heading into 2013. Caldwell said he wants to immediately explore every avenue possible to turn the Jaguars around.

"For that to happen as seamlessly as we want, and as quickly as our fans deserve, I feel it is in everyone's best interests for an immediate and clean restart," Caldwell said.

Mularkey, who went 2-14 this season, became the eighth head coach fired since the end of the regular season. He looked like he would be one and done when owner Shad Khan parted ways with general manager Gene Smith last week and gave Mularkey's assistants permission to seek other jobs. Even though Khan ultimately hired Mularkey, Smith directed the coaching search last January that started and ended with the former Atlanta Falcons offensive coordinator.

"Mike Mularkey is leaving our organization with my utmost respect," Khan said. "Mike gave the Jaguars everything he had on and off the field, and his efforts as our head coach will always be appreciated."

Mularkey's brief tenure — he didn't even last a year — was filled with mistakes. His biggest one may have been his loyalty to Smith, who assembled a roster that lacked talent on both sides of the ball.

Mularkey probably stuck with Smith's franchise quarterback, Blaine Gabbert, longer than he should have. And the coach's insistence that the team was closer than outsiders thought and his strong stance that he had the roster to turn things around became comical as the losses mounted. The Jaguars lost eight games by at least 16 points, a staggering number of lopsided losses in a parity-filled league.

Mularkey would have been better served had he said publicly what he voiced privately: that the Jaguars didn't have enough playmakers or a starting-caliber quarterback.

Instead, he never conceded that Jacksonville was a rebuilding project that needed time.

Mularkey signed a three-year contract on Jan. 11, 2012, getting a second chance to be a head coach six years after resigning with the Buffalo Bills.

His return was shaky from the start.

His best player, running back Maurice Jones-Drew, skipped offseason workouts as well as training camp and the preseason in a contract dispute. His first draft pick, receiver Justin Blackmon, was arrested and charged with aggravated DUI in June. And his team was riddled with injuries, including key ones to linebacker Daryl Smith and Jones-Drew.

Even things he had control over went awry.

He had to backtrack after saying Chad Henne would compete with Gabbert for the starting job in March. He created a stir by threatening to fine players up to $10,000 for discussing injuries. He initially played rookie receiver Kevin Elliott over Cecil Shorts III early on. And he really irked some players with tough, padded practices late in a lost season.

Throw in the way he handled injuries to receiver Laurent Robinson (four concussions before going on IR) and Jones-Drew (admittedly should have had foot surgery sooner), and there were reasons to doubt whether Mularkey was cut out to be a head coach. Dating back to his final season in Buffalo, Mularkey has lost 20 of his last 23 games.

Nonetheless, if Khan really wanted to fire Mularkey, he would have done after the season finale along with Smith.

So this was Caldwell's call.

Caldwell and Mularkey spent four years together in Atlanta, getting to know each other well enough that Caldwell didn't need a sit down with Mularkey after he got the GM job Tuesday.

Caldwell and Khan have a news conference scheduled for Thursday afternoon.

Potential replacements for Mularkey include former Chicago Bears coach Lovie Smith, Indianapolis Colts offensive coordinator Bruce Arians, St. Louis Rams offensive coordinator Brian Schottenheimer and San Francisco 49ers offensive coordinator Greg Roman.

Schottenheimer was up for the Jacksonville job last season, and Roman has been linked to the Jaguars since Caldwell became the leading candidate to replace Smith.

Roman and Caldwell were teammates and roommates in the 1990's while attending John Carroll University.

Atmosphere of Venus Has Strange Magnetic ‘Ropes’

Strange, newly discovered structures in Venus’ atmosphere are redrawing scientists’ perceptions of the planet’s magnetic environment.

The European Space Agency’s Venus Express spacecraft spotted these enormous magnetic entities — called flux ropes — stretching for hundreds of miles in the planet’s upper atmosphere, above the poles.

Flux ropes have been seen before around other planets, including Earth. They transport superheated plasma gas from one side of the “rope” to the other. But on Venus, scientists don’t know why these phenomena form in the atmosphere, according to a paper published Dec. 26 in the journal Geophysical Research Letters. How long they exist, and how they dissipate, are also mysteries.

“It is a huge surprise,” study leader Tielong Zhang, who holds dual affiliations at research institutions in China and Austria, wrote in an email to SPACE.com. [Photos of Venus, the Mysterious Planet]

Twisting magnetic lines

Magnetic flux ropes come together from twisted magnetic field lines. They have been spotted in magnetic fields all over the solar system.

On Earth, flux ropes form near the face of the planet opposite the sun. The stream of charged particles known as the solar wind flows around the planet and creates a “magnetotail” of charged particleson the other side.

Periodic solar outbursts known as coronal mass ejections arise from a type of flux rope. The delicate structures sit on top of the sun and transport matter and superheated gas from one part of the sun to another. Researchers believe that when the flux ropes become unstable, that’s when the sun erupts.

Venus stands apart from most other planets in the solar system, however, because it has no magnetic field. Zhang said the ionosphere (or upper atmosphere) of Venus acts as an obstacle to the solar wind.

When Venus’ atmosphere has a higher pressure than the incoming solar wind field, the ionosphere is considered “unmagnetized,” meaning that it’s free of all but the smallest magnetic field structures.

The ionosphere of Venus stays unmagnetized most of the time, until the solar wind reaches a higher pressure than the surrounding atmosphere and magnetizes it. In these conditions, relatively small flux ropes can form due to the higher speed of the solar wind rolling over the slower ionosphere, researchers said. [The 10 Weirdest Facts About Venus]

“The ionosphere is filled with these very small — kilometers across — flux ropes,” Christopher Russell told SPACE.com. Russell is a space physicist at UCLA and a co-investigator on Zhang’s study.

“That might seem large to somebody walking down the street, but in terms of the size of the ionosphere, they are small,” said Russell, who was also the principal investigator of NASA’s Venus Pioneer missionthat first spotted these structures.

Scientists have known about these small flux ropes for a generation, since Pioneer orbited Venus in the late 1970s and early 1980s.

But the giant flux ropes were completely unknown until Venus Express — which was in a different orbit than Pioneer — spotted them with its magnetometer in 2008 and 2009. And they likely are created by a very different process, Russell said.

Frequent flux ropes

Venus Express saw the giant flux ropes in magnetized regions of the Venusian ionosphere over the poles, where that region of the atmosphere of Venus made its closest approaches to the planet. According to the paper, these ropes happen “quite often” and are hundreds of miles long, about as long as the depth of the ionosphere.

Scientists determined that the flux ropes form from solar particles on the side of the planet facing away from the sun, in the magnetotail. As the ropes’ magnetic fields twisted tighter, they passed from the equator region to the poles.

“It seems to be associated with a process known as reconnection, which is magnetic field lines joining up together and forming a new magnetic configuration,” Russell said. On Earth, this is the driving force behind the planet’s spectacular auroras, which also tend to originate in the magnetotail.

As Venus’ flux ropes move over the poles, the local magnetic field they create is stronger than the background, Russell added. To better understand them, the scientists are now working on a statistical survey to figure out how often flux ropes occur in Venus’ ionosphere, and where they are.

Zhang, who is the principal investigator for Venus Express’ magnetometer instrument, noted that giant flux ropes were previously found in the atmosphere of Mars — but only in the southern hemisphere. Mars, like Venus, does not have a planet-wide magnetic field.

“The observation and formation of the large flux rope at Mars might raise speculative questions related to the giant flux ropes at Venus,” Zhang said, but added it was too early to draw direct links.

At least one study, according to Zhang’s paper, has drawn a link between the magnetic rocks found on Mars and the flux ropes found above the Red Planet.

But Mars is a much different environment than Venus, so the giant flux ropes found by Venus Express could arise for another reason, he said.

Zhang works for both the University of Science and Technology of China and the Austrian Academy of Sciences, while the rest of his paper’s research team hails from Austria, the United States, Germany, China and the United Kingdom.

'Lincoln' leads Academy Award contenders with 12 nominations

With a conspicuous diss of Kathryn Bigelow, the un-nominated director of “Zero Dark Thirty,” the Academy Awards nominations were announced Thursday morning.

“Zero Dark Thirty” was one of nine films given the best picture nomination nod. The others: “Beasts of the Southern Wild”; “Silver Linings Playbook”; “Lincoln”; “Les Miserables”; “Life of Pi”; “Amour”; “Django Unchained”; and “Argo.” With 12 nominations total, director Steven Spielberg’s “Lincoln” led this year’s pack, unusually full of films that have reached a broad mainstream audience. “Life of Pi” came in with 11 nominations; “Silver Linings Playbook” and “Les Miserables” received eight.

The best actress Oscar nominees include the oldest-ever performer in that category (Emmanuelle Riva, 85, for “Amour”) as well as the youngest (Quvenzhane Wallis, 9, “Beasts of the Southern Wild”). They’ll compete for the Feb. 24 Oscars against Naomi Watts (“The Impossible”), Jessica Chastain (“Zero Dark Thirty”) and Jennifer Lawrence (“Silver Linings Playbook”).

To the surprise of no one on this planet or any other, Daniel Day-Lewis led the best actor competition for “Lincoln.” His fellow nominees: Denzel Washington, “Flight”; Hugh Jackman, “Les Miserables”; Bradley Cooper, “Silver Linings Playbook”; and in the year’s most unsettling performance, Joaquin Phoenix, “The Master.”

“Silver Linings Playbook” fared well, against some predictions, scoring a supporting actor nomination for Robert De Niro and a supporting actress nod for Jacki Weaver. Other supporting actors nominated include Christoph Waltz for “Django Unchained”; Philip Seymour Hoffman, “The Master”; Alan Arkin, “Argo”; and Tommy Lee Jones,” Lincoln.” All have won Oscars before.

Along with Weaver, Sally Field received a supporting actress nomination, hers for “Lincoln.” The competition: Anne Hathaway, singing her guts out all the way to the podium on Feb. 24 (I’m guessing) for “Les Miserables”; Helen Hunt for “The Sessions” (more of a leading role, in fact); and Amy Adams as the Lady Macbeth of the action in “The Master.”

It’s a huge showing for “Beasts of the Southern Wild,” whose director, Benh Zeitlin, goes toe to toe against his fellow directing nominees David O. Russell (“Silver Linings Playbook”), Ang Lee (“Life of Pi”), Michael Haneke (“Amour”) and Spielberg. Along with “Zero Dark Thirty” director Bigelow, “Argo” helmer Ben Affleck, widely expected to be nominated ... wasn’t.

Syria denounces peace envoy who hinted Assad must go

BEIRUT (Reuters) - Syria denounced international envoy Lakhdar Brahimi as "flagrantly biased" on Thursday, casting doubt on how long the U.N.-Arab League mediator can pursue his peace mission.

The Syrian Foreign Ministry was responding to remarks by Brahimi a day earlier in which he ruled out a role for President Bashar al-Assad in a transitional government and effectively called for the Baathist leader to quit.

"In Syria...what people are saying is that a family ruling for 40 years is a little bit too long," Brahimi told the BBC, referring to Assad, who inherited his post from his father Hafez al-Assad, who seized power in 1970 and ruled for 30 years.

"President Assad could take the lead in responding to the aspiration of his people rather than resisting it," the veteran Algerian diplomat said, hinting the Syrian leader should go.

The Foreign Ministry in Damascus said it was very surprised at Brahimi's comments, which showed "he is flagrantly biased for those who are conspiring against Syria and its people".

The ministry later said it was nevertheless still willing to work with the envoy to find a political solution to the crisis.

Brahimi has had no more success than his predecessor Kofi Annan in his quest to resolve the 21-month-old conflict in which more than 60,000 people have been killed.

British Foreign Secretary William Hague warned that violence in Syria might worsen and said the international community must "step up" its response if it does.

So far regional rivalries and divisions among big powers have stymied any concerted approach to the upheaval, one of the bloodiest to emerge from a series of revolts in the Arab world.

Russian and U.S. diplomats, who back opposing sides of the war, will meet Brahimi in Geneva on Friday.

Ahead of the meeting, Russia repeated its insistence that Assad must not be pushed from power by external forces and that his exit must not be a precondition for negotiations.

"Only the Syrians themselves can agree on a model or the further development of their country," Foreign Ministry spokesman Alexander Lukashevich said.

"MASK OF IMPARTIALITY"

Syria's al-Watan newspaper said Brahimi had removed his "mask of impartiality" to reveal his true face as a "a tool for the implementation of the policy of some Western countries".

On Sunday Assad, making his first public speech in six months, offered no concessions and said he would never talk to foes he branded terrorists and Western puppets.

As peace efforts floundered, rebels battled for a strategic air base for a second day, pursuing a civil war that had briefly receded for some Damascus residents who set aside their differences to play in a rare snowfall that blanketed the city.

For a few hours, people in the capital dropped their weapons for snowballs and traded hatred for giggles.

"Last night, for the first time in months, I heard laughter instead of shelling. Even the security forces put down their guns and helped us make a snowman," Iman, a resident of the central Shaalan neighborhood, said by Skype.

There was no respite on other battlefronts, with heavy fighting around the Taftanaz base in northwestern Syria, which insurgents are trying to capture to extend their grip on Idlib province and weaken Assad's control of the skies.

Rebels assaulted the airport's main buildings and armory using heavy guns, tanks and other weapons and appeared to have overrun half the area of the base, said Rami Abdelrahman, director of the Syrian Observatory for Human Rights, a pro-opposition group that monitors the conflict from abroad.

"Now, it's serious," he said.

The air base has been used to launch helicopter attacks in the region, and its loss would be a blow to the government's ability to defend its positions there, Abdelrahman said.

MISSILE LAUNCH

Insurgents have tried to take the base for months, but have been bolstered by the recent arrival of Islamist fighters including the al Qaeda-linked al-Nusra Front, he added.

There was no immediate government account of the fighting, which could not be confirmed independently.

Opposition forces have seized swathes of territory in northern Syria in recent months, but remain vulnerable to attack by the military's planes and helicopters - hence their strategy of trying to capture air bases such as the one at Taftanaz.

There was no word on whether the firing of a short-range ballistic missile inside Syria on Wednesday, reported by a NATO official, was linked to the fighting at Taftanaz.

NATO could not confirm the type of missile used, but the description fit the Scuds that are in the Syrian military's armory, the official added, describing the latest launch and similar ones last week as "reckless".

A NATO official said that since the start of December 2012, the alliance had detected at least 15 launches of unguided, short-range ballistic missile inside Syria.

Neither side has gained a clear military advantage in the war pitting mostly Sunni Muslim rebels against security forces dominated by Assad's minority, Shi'ite-linked Alawite sect.

The Observatory also reported fighting between rebels and troops in the Sayyida Zeinab area of Damascus, and air raids were reported in the capital's Maleiha area and eastern suburbs.

Despite some support from Sunni regional powers including Turkey, Saudi Arabia and Qatar, the rebels remain largely disorganized, fragmented and ill-equipped. Poor discipline, looting and insecurity in some insurgent-held areas have also eroded their support from civilians.

Turf wars between rebel units and with Kurdish groups have also beleaguered the armed opposition. On Thursday, a senior Islamist commander was assassinated near the border with Turkey, Syrian rebels and political opposition sources said.

Thaer al-Waqqas, northern commander of al-Farouq Brigades, had been suspected of involvement in the killing four months ago of a member of al-Nusra Front.

He was shot dead at a rebel position in the town of Sermin, a few kilometers from Turkey, the sources said.

Wall Street modestly higher as Alcoa beats revenue estimates

NEW YORK (Reuters) - Stocks edged up on Wednesday after Alcoa got the earnings season under way with better-than-expected revenue and an encouraging outlook for the year.

The market's rise came after two-days of declines, with few catalysts to give direction and investors fretting about the start of earnings season after the prior quarter's lackluster performance.

Alcoa Inc said late on Tuesday it expects global demand for aluminum to grow in 2013, though the company expressed concern about the impact on business from a confrontation in Washington over the U.S. budget. Shares of Alcoa, the largest U.S. aluminum producer, were trading flat in early afternoon at around $9.12, after earlier trading higher.

Overall, corporate profits were expected to beat the previous quarter's meager 0.1 percent rise. Both earnings and revenues in the fourth quarter were expected to grow by 1.9 percent, according to Thomson Reuters data.

But the lowered expectations leave room for companies to surprise investors even if their results are not particularly strong, analysts said.

The current quarter was shaping up like the previous one, with companies lowering expectations in recent weeks, said James Dailey, portfolio manager of TEAM Asset Strategy Fund in Harrisburg, Pennsylvania.

"So the big question and focus is on revenue, and Alcoa had better-than-expected revenue," calming the market a little, Dailey said.

The Dow Jones industrial average <.dji> was up 56.44 points, or 0.42 percent, at 13,385.29. The Standard & Poor's 500 Index <.spx> was up 3.31 points, or 0.23 percent, at 1,460.46. The Nasdaq Composite Index <.ixic> was up 11.50 points, or 0.37 percent, at 3,103.31.

Shares of Herbalife Ltd rose 3.5 percent to $39.70, following news that hedge fund manager Dan Loeb has taken a stake of more than 8 percent in the nutritional supplements seller, according to a regulatory filing. Herbalife has come under fire from prominent short-seller Bill Ackman, who has accused the company of being a "pyramid scheme," a charge it vehemently denies.

Facebook Inc shares rose above $30 per share for the first time since July, 2012. The social network sent out a media invitation on Tuesday saying, "Come and see what we're building." Facebook, which has been tight-lipped about its plans after its botched IPO in May, invited the media to its Menlo Park, California, campus on January 15.

Among other companies reporting earnings, Constellation Brands , whose labels include Robert Mondavi and Ravenswood wines, reported higher profit and raised its forecast. The stock was down 0.8 percent at $35.74.

Apollo Group Inc slid more than 11 percent after it reported lower student sign-ups for the third straight quarter and cut its operating profit outlook for 2013. Apollo's shares were last at $18.63.

AP Source: RG3 surgery repairs damage to ACL, LCL

WASHINGTON (AP) — Robert Griffin III had surgery to repair two ligaments in his troublesome right knee Wednesday morning, said a person familiar with the situation.

The Washington Redskins quarterback had his knee repaired by orthopedist James Andrews in Florida. The doctor had already diagnosed a torn lateral collateral ligament in his right knee. The person said Andrews also found and repaired damage found in Griffin's ACL.

The person spoke to The Associated Press on condition of anonymity because the Redskins had not made an announcement about the latest details surrounding the rookie quarterback's injury.

Now comes RG3's next challenge: a race against time to get healthy before the beginning of next season.

Griffin's recovery time will take several months at least but could extend into next season, depending on the extent of the damage. The process could also be speeded up because Griffin is known as a focused, determined competitor who would be expected to take his rehab as seriously as possible.

"Thank you for your prayers and support. I love God, my family, my team, the fans, & I love this game. See you guys next season," Griffin tweeted before the surgery began.

Athletes generally need nine to 12 months to make a full recovery from a torn ACL, although Minnesota Vikings running back Adrian Peterson made a remarkable return this season about eight months after tearing an ACL — and nearly broke the NFL's single-season rushing record.

Russ Paine, a physical therapist in Houston who worked with Peterson during his rehab, said the running back's timetable for returning to competition was in fact "pretty traditional."

"What's non-traditional is him almost breaking the rushing record," Paine said in a phone interview Wednesday.

Griffin reinjured his knee at least twice in Sunday's playoff loss to the Seattle Seahawks, prompting a national debate over whether coach Mike Shanahan endangered Griffin's career by not taking the team's franchise player out of the game sooner.

The first major injury to the knee came in 2009, when Griffin tore the ACL in the third game of the season while playing for Baylor. Griffin missed the rest of the year but returned in 2010 and won the Heisman Trophy in 2011.

Griffin sprained the LCL last month when he was hit by Baltimore Ravens defensive tackle Haloti Ngata at the end of a 13-yard scramble. Griffin missed one game and returned to play three more while wearing a bulky knee brace, his mobility clearly hindered.

Then, on Sunday, Griffin hurt the knee again as he fell awkwardly while throwing a pass in the first quarter against the Seahawks. He remained in the game, with Shanahan saying he trusted Griffin's word that all was OK.

Griffin finally departed in the fourth quarter, after the knee buckled while he was trying to field a bad shotgun snap.

The No. 2 overall pick in last year's draft, Griffin was one of several rookie quarterbacks to make an instant impact on the NFL this season. He set the league record for best season passer rating by a rookie QB and led the Redskins to their first NFC East title in 13 years.

But he also had to leave three games early due to injuries — two because of his knee and one because of a concussion — and missed a fourth altogether because of the knee.

NASA to Announce Launch of New Earth-Observing Satellite

NASA plans to announce tomorrow (Jan. 10) the launch of a new satellite, the Landsat Data Continuity Mission (LDCM), to monitor Earth’s landscape and the changes to it.

The new satellite, scheduled to launch Feb. 11, will replace the Landsat 5 satellite, which is to be decommissioned in the coming months, the U.S. Geological Survey reported in December.

The announcement will be made at 1 p.m. EST at NASA headquarters in Washington. You can watch it live here, as well as on NASA Television and the agency’s website.

Landsat 5 is the longest-operating Earth-observing satellite mission in history, according to the USGS. Launched in 1984 with a three-year design life, it has been taking images and recording changes on the Earth’s surface ever since. The satellite almost failed several times, but engineers brought it back to life. However, the recent failure of a gyroscope (which helps satellites maintain their orientation) left no option but to end the mission, the USGS said in its release.

“Any major event since 1984 that left a mark on this Earth larger than a football field was likely recorded by Landsat 5, whether it was a hurricane, a tsunami, a wildfire, deforestation or an oil spill,” USGS Director Marcia McNutt said in the statement. “We look forward to a long and productive continuation of the Landsat program, but it is unlikely there will ever be another satellite that matches the outstanding longevity of Landsat 5.”

The satellite monitored the effects of the devastating floods along the Mississippi River in 2011, snapped an image of the path of a tornado in Massachusetts that same year, and helped the effort to battle raging wildfires in Arizona.

LDCM, like Landsat 5, is a collaboration between NASA and the USGS that will continue the Landsat program’s 40-year data record of monitoring Earth from space. Landsat 5 has orbited the globe more than 150,000 times and recorded over 2.5 million images.

Karzai's U.S. visit a time for tough talk

The last time Presidents Obama and Karzai met was in May in Kabul, when they signed a pact regarding U.S. troop withdrawal.

(CNN) -- Afghan President Hamid Karzai is meeting this week with President Obama in Washington amid increasing ambivalence in the United States about what to do about the war in Afghanistan.

Americans are tired of the war. Too much blood and treasure has been spent. The White House is grappling with troop numbers for 2013 and with the nature and scope of any U.S. mission after 2014. With the persisting corruption and poor governance of the Afghan government and Karzai's fear that the United States is preparing to abandon him, the relationship between Kabul and Washington has steadily deteriorated.

As the United States radically reduces its mission in Afghanistan, it will leave behind a stalled and perilous security situation and a likely severe economic downturn. Many Afghans expect a collapse into civil war, and few see their political system as legitimate.

Karzai and Obama face thorny issues such as the stalled negotiations with the Taliban. Recently, Kabul has persuaded Pakistan to release some Taliban prisoners to jump-start the negotiations, relegating the United States to the back seat. Much to the displeasure of the International Security Assistance Force, the Afghan government also plans to release several hundred Taliban-linked prisoners, although any real momentum in the negotiations is yet to take place.

U.S. may remove all triips from Afghanistan after 2014

Washington needs to be careful that negotiations are structured in a way that enhances Afghanistan's stability and is not merely a fig leaf for U.S. and NATO troop departure. Countering terrorism will be an important U.S. interest after 2014. The Taliban may have soured on al Qaeda, but fully breaking with the terror group is not in the Taliban's best interest. If negotiations give the insurgents de facto control of parts of the country, the Taliban will at best play it both ways: with the jihadists and with the United States.

Negotiations of a status-of-forces agreement after 2014 will also be on the table between Karzai and Obama. Immunity of U.S. soldiers from Afghan prosecution and control over detainees previously have been major sticking points, and any Afghan release of Taliban-linked prisoners will complicate that discussion.

Karzai has seemed determined to secure commitments from Washington to deliver military enablers until Afghan support forces have built up. The Afghan National Security Forces have improved but cannot function without international enablers -- in areas such as air support, medevac, intelligence and logistical assets and maintenance -- for several years to come. But Washington has signaled that it is contemplating very small troop levels after 2014, as low as 3,000. CNN reports that withdrawing all troops might even be considered.

Everyone is hedging their bets in light of the transition uncertainties and the real possibility of a major security meltdown after 2014. Afghan army commanders are leaking intelligence and weapons to insurgents; Afghan families are sending one son to join the army, one to the Taliban and one to the local warlord's militia.

With Afghan president's visit, nations' post-2014 future takes shape

Patronage networks pervade the Afghan forces, and a crucial question is whether they can avoid splintering along ethnic and patronage lines after 2014. If security forces do fall apart, the chances of Taliban control of large portions of the country and a civil war are much greater. Obama can use the summit to announce concrete measures -- such as providing enablers -- to demonstrate U.S. commitment to heading off a security meltdown. The United States and international security forces also need to strongly focus on countering the rifts within the Afghan army.

Assisting the Afghan army after 2014 is important. But even with better security, it is doubtful that Afghanistan can be stable without improvements in its government.

Afghanistan's political system is preoccupied with the 2014 elections. Corruption, serious crime, land theft and other usurpation of resources, nepotism, a lack of rule of law and exclusionary patronage networks afflict governance. Afghans crave accountability and justice and resent the current mafia-like rule. Whether the 2014 elections will usher in better leaders or trigger violent conflict is another huge question mark.

Emphasizing good governance, not sacrificing it to short-term military expediencies by embracing thuggish government officials, is as important as leaving Afghanistan in a measured and unrushed way -- one that doesn't jeopardize the fledgling institutional and security capacity that the country has managed to build up.

U.S. likely to keep thousands of troops in Afghanistan after NATO forces leave

Karzai has been deaf and blind to the reality that reducing corruption, improving governance and allowing for a more pluralistic political system are essential for Afghanistan's stability. His visit provides an opportunity to deliver the message again -- and strongly.
