Maven’s Haven: NASA’s Next Mars Mission Preps for Launch

LITTLETON, Colo. – NASA‘s next mission to the Red Planet is undergoing extensive testing in preparation for its launch next year.

Here within a Lockheed Martin Space Systems high-bay cleanroom, technicians are in tender-loving-care mode, busily outfitting and testing the Mars Atmosphere And Volatile EvolutioN (Maven) spacecraft.

This probe has a literal thirst for knowledge.

The goal of Maven, a $ 670 million Mars orbiter, is to study how Mars loses its atmospheric gas to space, and the role this process has played in changing the Martian climate through time. Mars’ atmosphere is cold and dry today, but there was once liquid water flowing over the surface. So where did the atmosphere — and the water — go?  [Video: Maven to Hunt Mars' Lost Water]

Maven’s launch period is a 20 day window between Nov. 18 and Dec. 7, 2013. If the spacecraft is hurled Marsward on day one of that window, it will insert itself into orbit around the planet on Sept. 22, 2014.

Following a five-week commissioning phase, Maven is to settle into its primary mission, roughly in the opening days of November 2014.

Maven’s one-Earth-year mission allows thorough coverage of near-Mars space. The probe is built to answer questions about the history of Martian volatiles and atmosphere, essential data to help reveal the nature of planetary habitability.

Direct descendent

Maven is deep in assembly, test and launch operations, a critical phase dubbed ATLO, said Tim Priser, Lockheed Martin’s chief engineer for the spacecraft.

“If you look at the physical characteristics of Maven, it is a direct descendent of our Mars Reconnaissance Orbiter,” Priser told SPACE.com.

The fully loaded Maven tips the scale at the same weight of a GMC Yukon, a little over 5,620 pounds (2,550 kilograms). When its fixed solar arrays are stretched out, Maven’s wingtip-to-wingtip length is as long as a school bus, 37 feet (11.3 meters).

Over the last few months technicians have installed the subsystems on the main spacecraft structure — the avionics, power, telecomm, mechanisms, thermal systems, and guidance, navigation and control. The propulsion system was installed earlier this year and the spacecraft was powered up in August with flight software for the first time.

Characterize the beast

After the holidays, Maven will go through rigorous environmental testing, Priser said, “to characterize the beast.” That evaluation means moving Maven from its cleanroom to a nearby special facility in which the spacecraft undergoes shake, rattle and vibration that simulates the craft’s Atlas 5 rocket launch, as well as profiling its magnetic cleanliness.

“We’re going to shake the spacecraft on a new three-axis shake table,” Priser said.

As Maven’s chief engineer, Priser has been advised by others that have used the large test gear he’s likely not going to like what he sees — and might need a barf bag handy. “But when it gets through and out the other side, you feel a whole lot more confident.”

Priser said Maven is to be placed in a highly elliptical orbit around Mars, where it will use three instrument suites: The Particles and Fields Package; a Remote Sensing Package; and the Neutral Gas and Ion Mass Spectrometer. This set of Maven instruments is tuned to make comprehensive measurements essential to understanding the evolution of the Martian atmosphere. [Photos From NASA's Mars Reconnaissance Orbiter]

Deep-dip

The sensitivity of Maven’s science gear led to challenges in building the spacecraft, and called for very clever circuitry and wiring solutions to reduce interference with instruments, Priser said. Also, magnetometers on the spacecraft had to be positioned away from solar array magnetic perturbations.

From its elliptical orbit around Mars, Maven is slated to fly five “deep-dip” campaigns that skim the atmosphere — all part of the plan to probe the Red Planet’s upper atmosphere, ionosphere and interactions with the sun and solar wind.

An advisory group will keep an eye on atmosphere-influencing dust storms on the planet and provide counsel on the timing of Maven’s deep-dip maneuvers,  Priser said.

Smooth sailing

So far, the building and testing of Maven has gone smoothly, Priser said, “and all indicators are that it will continue to do that.” The Mars Reconnaissance Orbiter heritage of people and hardware experience has enabled the Maven project to go well, he said.

The target time for delivery of Maven to its Florida launch facility is the first week of August next year, Priser said.

Following liftoff, an early nerve-wracking item on the Maven outbound checklist is getting the solar arrays deployed, said he added. En route to Mars, instrument health checks will be performed and the spacecraft’s magnetometers are to be turned on to start collecting data.

Maven will then make a series of propellant-gulping maneuvers to finesse itself into the desired science orbit. Valuable Maven science can be done for a full nine years of a possible extended mission.

But first things first, Priser said: “We’ve got a fixed launch window breathing down our neck,” he concluded.

Instrument providers

Instruments on the spacecraft are provided by the University of California, Berkeley, the University of Colorado, Boulder, and NASA Goddard, with the Centre d’Etude Spatiale des Rayonnements in Toulouse, France, providing the sensor for one instrument.

NASA’s Jet Propulsion Laboratory in Pasadena, Calif., has provided the Electra telecommunications relay package that’s onboard Maven. The mission is part of NASA’s Mars Scout program.

The Laboratory for Atmospheric and Space Physics (LASP) at the University of Colorado, Boulder is in charge of coordinating the science team and distributing the science derived by Maven. Bruce Jakosky from University of Colorado is the Maven principal investigator.

Overseeing the health of the spacecraft as it operates around Mars will be done via the Lockheed Martin Mission Support Area.

On gun control, look to Biden

Rebecca Puckwalter-Poza says Vice President Joe Biden was a leader on gun control in the Senate.

STORY HIGHLIGHTS

• Rebecca Buckwalter-Poza: Obama has apparently tapped Biden as gun control point man


• She says he was leader in Senate on issue, shepherding 1994 gun control legislation


• It banned manufacture of many semi-automatic guns,criminalized high-capacity magazines


• Writer: Biden worked across aisle; he's adroit, determined statesman, right man for job

Editor's note: Rebecca Buckwalter-Poza served as deputy national press secretary of the Democratic National Committee during the 2008 election.

(CNN) -- President Obama's poignant speech at Sunday's interfaith vigil in Newtown, Connecticut, set the tone for our mourning. Now, America's path forward will be decided out of the spotlight. The question of whether the tragedy at Sandy Hook Elementary School will linger only in memory or be memorialized by an enduring shift in gun policy can only be answered by the legislature.

Incoming Judiciary Committee chair Sen. Diane Feinstein has announced she will introduce an enhanced assault weapons ban on the first day of the new Congress, but the fate of that legislation is in the hands of Vice President Joe Biden.

Biden will reportedly lead the administration's political response.

Rebecca Buckwalter-Poza

No politician could be better suited to the challenge of passing federal gun control legislation than Biden. Over the past four decades, Biden has been one of the most consistent and effective advocates of gun control and violence prevention legislation. In 1994, Biden shepherded the Violent Crime Control and Law Enforcement Act through the Senate, a near miracle six years in the making.

After Biden wrote the Violent Crime Control and Law Enforcement Act in 1988, Republicans quickly filibustered, blocking the bill for four years. He steered "the Biden crime bill" through the lengthy filibuster by negotiating with Republicans and making revisions. "Every single line in that bill was written with every single major Republican a part of it," Biden said in a September 12, 1994, interview on the Charlie Rose show.

The Clinton administration and then-Sen. Biden repeatedly refused to make concessions that would have jeopardized the substance of the act, even after debate over the amendment we know as the federal assault weapons ban imperiled the entire bill. Instead of backing down, Biden took on Republican Sens. Phil Gramm and Orrin Hatch and faced opponents attacking the bill as taxpayer-funded "dance lessons and midnight basketball for robbers and rapists."

France: Where fear and taboo control guns more than laws

Biden did not budge: "Make no mistake, this is about guns, guns, guns." The crime bill passed the Senate in November 1993.

When the bill foundered in the House, Biden persevered. It reached President Clinton's desk thanks to an unexpected, eleventh-hour push from a "Lost Battalion of Republicans" led by Rep. Mike Castle of Delaware. He'd been swayed during a series of meetings with the House Speaker and other House Republicans, at which Biden was the only Senator in attendance.

The resulting legislation banned the manufacture of 19 types of semi-automatic firearms and criminalized the possession of high-capacity magazines. The process taught a critical lesson: When otherwise "pro-gun'" lawmakers have to choose between a crime bill including a gun ban and inaction, it is more than possible for them to vote to protect Americans. Unfortunately, the assault weapons ban expired in 2004. Since then, numerous lawmakers, including Joe Biden, have tried and failed to get the ban renewed.

Congress now has a rare opportunity to take new action on gun control. After Newtown, proponents of stricter gun legislation are backed by public opinion and bolstered by a surge of political support. The "pro-gun" wing of the GOP and the National Rifle Association remain silent even as their supporters are defecting publicly.

Democratic Sens. Harry Reid and Joe Manchin, whose voting record earned them the NRA's "top rating," have backed off their "pro-gun" positions and declared that "everything must be on the table" for legislative debate. The 31 pro-gun senators have not spoken since Friday's tragedy, signaling the possibility that some of them might be changing their minds on guns, too.

Lawmakers are essentially being asked to consider an updated version of the 1994 assault weapons ban. On Sunday, Feinstein promised the legislation "will ban the sale, the transfer, the importation and the possession" of assault weapons and ban high-capacity magazines as well as "clips of more than ten bullets."

Biden will likely support a new ban on assault weapons and push for improvements. His 2007 Crime Control and Prevention Act would not only have renewed the ban but required background checks for all gun purchases, closing the "gun show loophole.'" Biden has also called on Congress to address the relationship of mental illness to violence in the wake of the Virginia Tech shootings.

Was your gun banned?

The president cautioned Americans Sunday, saying "no single law, no set of laws can eliminate evil from the world, or prevent every senseless act of violence in our society. But that can't be an excuse for inaction. Surely, we can do better than this."

In his first term, however, Obama practiced a policy of appeasement, failing to block the expansion of gun rights or promote gun control. To ensure Congress passes tough, comprehensive gun control laws rather than settling for a watered-down version, as with health care, Obama must let Biden lead.

Why? Biden has distinguished himself as an adroit and effective statesman in both the legislative and the executive branches. The former six-term senator has a deft touch with moderate and conservative counterparts: in 2008, he eulogized Strom Thurmond. As vice president, he has spearheaded the implementation of the American Recovery and Reinvestment Act. Moreover, Biden has a particular passion for protecting students and educators. His wife, Jill Biden, has been teaching for more than 30 years.

The deaths of 20 first-graders and six adults compel all Americans as sons and daughters, fathers and mothers, uncles and aunts, to consult their moral compasses. Legislators face a greater responsibility: a moral imperative to pass any legislation that could possibly prevent a future Newtown, Aurora, Oak Creek or Blacksburg.

Opinion: Gun violence is a national security issue

As Obama ministers to the American people and offers words of comfort, Biden must move lawmakers to action. In 1994, Biden warned his colleagues, "we simply can't let the gun lobby deny to the American people the vital benefits in this bill." Biden must once more appeal to Congress to enact gun control. If anyone can succeed in those chambers, it's Joe Biden.

Theater review: Hilarious, hometown 'Book of Mormon'

Most of the audience flocking to “The Book of Mormon,” which officially descended on Chicago Wednesday night like satirical manna from some warped “South Park” heaven, are looking for amusement and escape. They'll surely find salvation from the rough old world in this new production of the deliciously over-eager 2011 Broadway hit, newly crafted for Chicago with a clutch of utterly committed, fresh-faced, faux-Mormon lads.

The true revelation in this brand new Chicago production — directed by Casey Nicholaw and Trey Parker and that stands up well to the original Broadway edition — is one Ben Platt, a hilariously funny young actor who finds an entirely different way into Elder Cunningham, the loser-geek Mormon, first played in New York by Josh Gad. He is the partner on this mission to Uganda for the alpha Elder Price (Nic Rouleau, who comes direct from Broadway and is also sharp and generally terrific, although very much in the original mold of the role). Platt, whose comic instincts are exquisite, really leans into this part, throwing himself out there with the abandonment of youth and shrewdly pushing the sincerity and charm of the character while downplaying the obvious manifestation of his quirks. Physical resemblance notwithstanding, Platt kicks the dangerous Jonah Hill-like cliches half way to Christendom, and makes the sidekick role about four times as funny and ten times as believable. He's no “American Idol” vocalist, but you won't care.

Laughs flow like Mormon wagon trains rolling West. But “The Book of Mormon,” like the enigmatic volume it lampoons so mercilessly, is actually a many-layered beast and therein, verily, lies its brilliance.

I'll try and not spoil narrative surprises. Somehow, the writing and composing team of Trey Parker, Robert Lopez and Matt Stone managed to poke wicked fun at the all-American religion without frying on the third rail of religious faith — and all the while convincing their audience that they actually are enjoying a rather sweet show.

“The Book of Mormon” is exquisitely toned. It brilliantly exploits the protection afforded by edges and extremes and mitigates its use of gags about such comedic untouchables as Jesus Christ, AIDS, Africa and genital mutilation (and those are the printable topics) with an earnestness impossible for even a nervous prude to resist. On Wednesday, those prudes were sputtering into their shirt collars with mirth.

In terms of risky content, “The Book of Mormon” makes the Monty Python boys look like they were writing the Acts of the Apostles. Yet it has a sweetness that few other satirical dramatic works have achieved. These Mormons are so lovable you feel half-inclined to take a couple of ‘em home with you. (It’s not like anyone ever wanted to give Mel Brooks a hug.)

Thanks mostly to Lopez, the show not only has a strikingly traditional and whip-tight musical structure; fans of the genre will recognize little stylistic spoofs of “Defying Gravity” from “Wicked,” “Tomorrow” from “Annie” and, of course, the hilarious Act 2 centerpiece wherein earnest Ugandans mangle Mormon doctrine in a skewering of “The Small House of Uncle Thomas” from “The King and I.” Jesus also looks remarkably like Prince Herbert from “Spamalot.”

But for those who hate musicals — and plenty of “South Park” fans are in that category — the caustic, relentless Parker-Stone worldview is very much is in evidence—especially in the truly inspired “spooky Mormon Hell” nightmare sequence centered on Adolf Hitler, Johnnie Cochran (“if it don't fit ..”) and dancing cups of illicit, mock Starbucks. These, they declare, are what keeps the members of the Church of Jesus Christ of Latter-day Saints awake at night. They may well be right. This show steers closer to the truth than you might think.

On a further viewing, I was blown away again by the disciplined narrative logic these writers applied to their outrageous storytelling. That's what comes of creating a TV show from whole imaginative cloth, almost every week for 16 years. One learns how to ensure the outlandish makes perfect sense.

Look behind the gags and you can find much pondering of the central problem faced by all people of faith: the apparent inability of religion to end the suffering of the innocent. You can find discussion of how faith is an all-or-nothing proposition; who could believe about 50 percent of Mormonism? The show lampoons the ability of persons of faith to compartmentalize and, most brilliantly of all, the pervasive nature of racial condescension. Indeed, it's in the racial arena (speaking of third rails) that this show is at its most risky and most admirable, as when white Mormon missionaries sing “We Are Africa” (a dead-on take-down of the smugness of “We Are the World”) even as actual Africans (well, African characters) stare at them in quiet amazement. Chicago actor James Vincent Meredith, who plays Mafala likes he's doing Athol Fugard, is a huge asset to the show.

The one performer who needs work is Syesha Mercado, who plays the lead ingenue role of Nabulungi (her name is constantly bungled as “Neutrogena” and the like by Elder Cunningham). Mercado sings well, albeit at a certain remove, but she has yet to grab hold of the necessary vulnerability of her character and hit the lyrical gags. She was a late replacement and surely will improve with time. Pierce Cassedy, as Elder McKinley (a Mormon who insists on turning off his gay identity) is hilarious and, more importantly, very poignant.

With tickets this scarce and prices this high, you might well wonder if “The Book of Mormon” is worth your time and elevated expectations. Be not afraid, suburban pilgrim. The Chicago production pulses with the just the right combination of Broadway production values, proven material, sufficient buy-in by the original creative team (who all took a bow on opening night) and new young men on a mission, not quite from God.

Egypt opposition vows to fight on against Islamist charter

CAIRO (Reuters) - Egypt's opposition, facing defeat over a new constitution in a referendum this weekend, urged its supporters to reject the Islamist-backed charter and pledged to fight on to amend it during elections expected next year.

Forty-eight hours before the second round of the plebiscite, the main opposition coalition of liberals, leftist, Christians and secular Muslims called for a "no" vote against a document it views as leaning too far towards Islamism.

The first day of voting last weekend resulted in a 57 percent majority in favor of the constitution, promoted by President Mohamed Mursi as a vital step in Egypt's transition to democracy almost two years after the fall of Hosni Mubarak.

The second stage on Saturday is expected to produce another "yes" vote as it covers areas of the country that are seen as more conservative and likely to back Mursi.

The National Salvation Front, the main opposition coalition, said a "no" vote meant taking a stand against attempts by the Muslim Brotherhood, Mursi's political backers, to dominate Egypt.

"For the sake of the future, the masses of our people should strongly and firmly say 'no' to injustice and 'no' to the Brotherhood's dominance," the Front said in a statement.

A senior Front member, Abdel Ghaffar Shokr, head of the Popular Socialist Coalition Party, said that if the constitution was approved, the opposition would go on fighting to change it.

"That's why we will participate in the legislative election because it is the only way to amend the constitution," he said.

The constitution must be in place before elections can be held. If it passes, the poll should be held within two months.

In an attempt to mobilize voters, the opposition said it planned to hold public meetings, distribute flyers and send cars equipped with loudspeakers through the streets.

A street protest against the constitution in Cairo this week attracted only a few hundred people, well down on the numbers drawn to previous such events.

ISLAMIST GROUPS

Islamist groups are planning a mass protest in Alexandria on Friday, a move likely to raise tensions a day before the vote.

The rally by the Muslim Brotherhood was called after a violent confrontation between Islamists and the opposition in Egypt's second city last week that ended with a Muslim preacher besieged inside his mosque for 14 hours.

The run-up to the referendum has been marked by often violent protests in which at least eight people have died.

U.N. Secretary-General Ban Ki-moon called for the final stage of the referendum to pass off peacefully so the country can focus on building "a pyramid of democracy in the heart of the Arab world".

"I sincerely hope there should be no further violence and the protest must be carried out in a peaceful manner so people will be free to express their views," Ban told reporters in New York on Wednesday.

Mursi and his backers say the constitution is needed to advance Egypt's transition from decades of military-backed autocratic rule. Opponents say it is too Islamist and ignores the rights of women and of minorities, including 10 percent of Egyptians who are Christian.

Demonstrations erupted when Mursi awarded himself extraordinary powers on November 22 and then fast-tracked the constitution through a drafting assembly dominated by his Islamist allies and boycotted by many liberals.

The referendum is being held over two days because many of the judges needed to oversee polling stayed away in protest.

Judicial authorities on Thursday named the judges who will supervise polling stations on Saturday. The opposition cited a lack of judges at some polling stations in a list of alleged irregularities in the first round.

In order to pass, the constitution must be approved by more than 50 percent of those voting.

Stock futures point to higher open, Oracle up early

NEW YORK (Reuters) - Stock futures pointed to a higher open on Wednesday as the latest offers in ongoing U.S. budget negotiations underlined hopes for a deal, while technology shares were lifted by strong results from Oracle.

The S&P 500 is on track to extend its best two-day run in a month, a sign that investors are looking past the "fiscal cliff," a combination of tax hikes and spending cuts many fear could push the economy into recession if they take effect next year.

President Barack Obama's most recent offer to Republicans in the ongoing fiscal talks made concessions on taxes and social programs spending, amid concerns from Senate Democrats. House Speaker John Boehner said he remained hopeful about an agreement, though the offer was "not there yet." [ID:nL1E8NI331]

"Both Obama and Boehner have been making concessions, suggesting a deal will get done before the deadline, resulting in an acceleration in stock buying," said Adam Sarhan, chief executive of Sarhan Capital in New York.

Tech shares will be in focus a day after Oracle Corp reported earnings that beat expectations on strong software sales growth. Shares rose 2.7 percent to $33.78 in premarket trading.

FedEx Corp reported second-quarter revenue that beat expectations, but said its earnings in the quarter had been impacted by Superstorm Sandy. Shares rose 1.3 percent to $93.53 before the bell.

S&P 500 futures rose 3.9 points and were above fair value, a formula that evaluates pricing by taking into account interest rates, dividends and time to expiration on the contract. Dow Jones industrial average futures added 37 points and Nasdaq 100 futures rose 9 points.

The S&P has gained 2.3 percent over the past two sessions, the first time it has notched two straight days of 1 percent gains since late July. Markets have been supported by any indication agreement might be reached, with banks and energy shares- groups that outperform during periods of economic expansion - leading gains.

"We've been breaking above levels of resistance, including the 50-day moving average and the November high, so from a technical standpoint we're seeing a lot of improvement," Sarhan said. "We're set up for a strong 2013."

Trading volume has been light ahead of the holidays and as some caution remains over the cliff. Equities have struggled to gain ground in recent weeks amid signs there was little room for compromise between the two political parties.

Knight Capital Group Inc climbed 4.1 percent to $76.68 in premarket after it agreed to be bought by Getco Holdings in a deal valued at $1.4 billion. The stock, which was devastated by a near-fatal trading error in August, remains down about 76 percent so far this year.

General Mills Inc reported earnings that beat expectations and raised its full-year profit view, citing a recent acquisition which lifted sales. Shares gained 1.5 percent to $42.40 in premarket trading.

Industrial machinery maker SPX Corp is closing in on a roughly $4.2 billion deal to buy rival Gardner Denver Inc , as it makes progress in securing financing, a source familiar with the matter said on Tuesday. Gardner shares rose 4.1 percent before the bell to $76.68.

U.S. housing starts fell 3 percent in November, impacted by Superstorm Sandy. Stock index futures barely reacted to the data.

Jets bench Sanchez, will start McElroy vs Chargers

NEW YORK (AP) — Mark Sanchez is no longer the New York Jets' franchise quarterback.

He might not even be the backup.

Rex Ryan decided to bench Sanchez on Tuesday in favor of Greg McElroy after the fourth-year quarterback had another miserable performance in a 14-10 loss at Tennessee on Monday night that eliminated New York from playoff contention.

"I think it's best for our team, and for this game," Ryan said during a conference call.

So, it'll be McElroy under center for his first NFL start when the Jets (6-8) play the San Diego Chargers at home Sunday. Ryan hasn't decided whether Sanchez or Tim Tebow — listed as the No. 2 quarterback — will be the backup.

While Sanchez blew the second chance Ryan gave him a few weeks ago, Tebow was leapfrogged by a third-stringer, fueling speculation that the team has little confidence in him as a quarterback.

"I have to look at what I think is the best for the team and not necessarily the individual," Ryan said. "I'll say this about Tim and I've always said it: I know he wants to help this team be successful in the worst way and there's no doubt about that."

Sanchez threw four interceptions Monday night and wasn't able to handle a low snap with the game on the line, ending the Jets' hopes to get back into the postseason.

Things got worse after the game for Sanchez, who received a series of death threats from one disgruntled fan on Twitter. League spokesman Greg Aiello said the NFL's security staff was aware of the man's threats and was working with the Jets to assist on the matter. The team declined comment through a spokesman.

Ryan said after the loss that he wasn't ready to decide who would start against the Chargers, but told Sanchez he would be making a change at quarterback by going with either McElroy or Tebow.

"He respected my decision," Ryan said. "That's not easy, that's for sure."

After talking to his staff and members of the organization Tuesday, Ryan chose McElroy.

"This is my opinion, and I do believe that it's best for our team that Greg is our quarterback," Ryan insisted. "I'm the guy that's making this decision. Every decision I make is based on what I believe is the best decision for the team."

But Ryan was vague in his answers to why he selected McElroy above Tebow, choosing after being asked several times to not go into detail about what specifically factored into the decision.

"I can answer this question a million ways, frontward, backward, sideways, anything else," Ryan said. "It's my decision and I based it on a gut feeling or whatever."

McElroy, a seventh-round pick last year out of Alabama, helped lead the Jets to a 7-6 win over Arizona on Dec. 2 when Ryan pulled Sanchez from that game late in the third quarter. McElroy had modest numbers — 5 of 7 for 29 yards — but threw for the only touchdown of the game, and nearly led another scoring drive as the Jets ran out the clock.

Ryan decided to stick with Sanchez after that game, saying that the one-time face of the franchise gave the Jets their best chance at winning as they remained in the playoff hunt.

But Sanchez struggled in a 17-10 win over Jacksonville and again even more in the loss to Tennessee. McElroy, who gave the Jets a huge spark in his first NFL action, was inactive for both games. That hurt New York on Monday night when Ryan was unable to turn to McElroy since he was not in uniform for the game. Instead, Ryan went to Tebow for one series — which had been part of the game plan — but it was unproductive and Sanchez came back in for the next offensive possession.

Sanchez leads the league with 24 turnovers, including 17 interceptions, and has turned the ball over 50 times since the start of last season. His future with the team is uncertain because he signed a contract extension with New York in March that included $8.25 million in guaranteed money for next season.

Ryan would not commit to Sanchez beyond this season, and wouldn't discuss what the depth chart will look like.

"We have two games left and that's where my focus is going to be," he said. "What's past that will be determined later."

Sanchez was regularly booed during home games this season, falling out of favor with the fans who were excited when the Jets traded up to take him with the fifth overall pick in the 2009 draft.

"Has he had better days than (Monday night)? Absolutely," Ryan said.

There certainly were some good moments for the former Southern California star, particularly in helping lead New York to the AFC championship game in each of his first two seasons, but he failed to take the next step in his development.

While his frequent mistakes in reading defenses and miscalculating throws are a huge reason for his struggles, Sanchez also wasn't helped by a constantly changing cast around him. Several of the team's top offensive players — Thomas Jones, Leon Washington, Jerricho Cotchery, Brad Smith, LaDainian Tomlinson, Plaxico Burress, Alan Faneca and Damien Woody — have all been released, traded or allowed to become free agents since Sanchez's rookie season. He is also working with his second offensive coordinator in Tony Sparano after an up-and-down three seasons with Brian Schottenheimer.

Tebow, acquired from Denver in March, has had a minor role in the offense after being expected to play a major part. He is recovering from two broken ribs that sidelined him for three games, but returned Monday night and had little impact. It would seem unlikely that Tebow, who helped lead the Broncos to the playoffs last season, will be back next season.

When Tebow arrived in New York, he often said he was "excited to be a Jet," but there's little doubt that he no longer feels that way. He has done his best to hide his frustration throughout the season, especially when the wildcat-style offense was talked up by Ryan and Sparano as a highlight of the offense.

Tebow has instead just been a spare part on an offense that ranks 30th in the NFL. He is 6 of 8 passing for 39 yards, and has run 32 times for 102 yards — playing a more significant role as the personal punt protector on special teams.

"People can speculate anything they want," Ryan said. Obviously, as a football team, we're 6-8 and nobody's happy about that and ultimately, I'm the one accountable."

Rocket with 3 astronauts takes off for ISS

BAIKONUR, Kazakhstan (AP) — A Soyuz spacecraft carrying three astronauts took off atop a towering Russian rocket on Wednesday, headed for the International Space Station.

It launched from Russia’s manned-space facility in the frigid steppes of Kazakhstan at 6:12 p.m. (1212 GMT). It separated from its final rocket stage and went into orbit about 15 minutes later.

American Tom Marshburn, Russian Roman Romanenko and Canadian Chris Hadfield will travel for two days in the capsule, before docking with the space station where three other astronauts are already on board.

The docking coming close to Christmas added to the high emotional valence of spaceflight for Hadfield.

“There are certain times of the year and certain times in life that are special by everybody’s traditions. In my family’s tradition, this is maybe the most special time of the year,” he said.

Around four hours before the launch, the astronauts posed for photos, ran final suit checks and chatted with relatives through protective glass designed to protect them from infection.

Romanenko was seen off by his father Yuri, who set a record for time spent in space during a mission in the 1970s.

“My dad carried out a spaceflight in a two-person crew … on a similarly cold day 35 years ago and that was one of the first long-term flights,” Romanenko said at a news conference on the eve of the launch.

Typically, the crew performs a final outdoor salute to top space officials before mounting the bus taking them to the Soyuz, but the practice was forgone on this occasion because of the severe cold; the temperature at launch time was -17 C (2 F).

Before the astronauts were tightly packed into the cramped capsule, they exchanged greetings with Russian Federal Space Agency chief Vladimir Popovkin.

Although space travel has long fascinated the general public, interest has flagged in recent decades as tightened budgets have constrained ambitions.

Hadfield displayed optimism about the future of the industry and said that the voyages to the moon, which last happened 40 years ago, set an important precedent.

“What we are doing today as a group is continuing through that door and learning the things we need to do and taking one small step at a time so that we can better understand where we are in the universe,” he said.

Arming teachers would halt massacres

William Bennett argues that schools would be safer with at least one armed person there who is well-trained in firearms use.

STORY HIGHLIGHTS

• William Bennett: Arming, training one person in a school could help prevent shootings


• He says armed people have stopped instances of mass killing


• Killers may target places where they know they can't be shot down, Bennett says


• Bennett: Guns help prevent crime and improve public safety

Editor's note: William J. Bennett, a CNN contributor, is the author of "The Book of Man: Readings on the Path to Manhood." He was U.S. secretary of education from 1985 to 1988 and director of the Office of National Drug Control Policy under President George H.W. Bush.

(CNN) -- On NBC's "Meet the Press" this past Sunday, I was asked how we can make our schools safer and prevent another massacre like Sandy Hook from happening again. I suggested that if one person in the school had been armed and trained to handle a firearm, it might have prevented or minimized the massacre.

"And I'm not so sure -- and I'm sure I'll get mail for this -- I'm not so sure I wouldn't want one person in a school armed, ready for this kind of thing," I said. "The principal lunged at this guy. The school psychologist lunged at the guy. Has to be someone who's trained. Has to be someone who's responsible."

William Bennett

Well, I sure did get mail. Many people agreed with me and sent me examples of their son or daughter's school that had armed security guards, police officers or school employees on the premises. Many others vehemently disagreed with me, and one dissenter even wrote that the blood of the Connecticut victims was ultimately on the hands of pro-gun rights advocates.

To that person I would ask: Suppose the principal at Sandy Hook Elementary who was killed lunging at the gunman was instead holding a firearm and was well trained to use it. Would the result have been different? Or suppose you had been in that school when the killer entered, would you have preferred to be armed?

Evidence and common sense suggest yes.

In 2007, a gunman entered New Life Church in Colorado Springs and shot and killed two girls. Jeanne Assam, a former police officer stationed as a volunteer security guard at the church, drew her firearm, shot and wounded the gunman before he could kill anyone else. The gunman then killed himself.

In 1997, high school student Luke Woodham stabbed his mother to death and then drove to Pearl High School in Pearl, Mississippi, and shot and killed two people. He then got back in his car to drive to Pearl Junior High to continue his killings, but Joel Myrick, the assistant principal, ran to his truck and grabbed his pistol, aimed it at Woodham and made him surrender.

These are but a few of many examples that the best deterrent of crime when it is occurring is effective self-defense. And the best self-defense against a gunman has proved to be a firearm.

LZ Granderson: Teachers with guns is a crazy idea

And yet, there is a near impenetrable belief among anti-gun activists that guns are the cause of violence and crime. Like Frodo's ring in "The Lord of The Rings," they believe that guns are agencies of corruption and corrupt the souls of whoever touches them. Therefore, more guns must lead to more crime.

But the evidence simply doesn't support that. Take the controversial concealed-carry permit issue, for example.

In a recent article for The Atlantic magazine, Jeffrey Goldberg, by no means an avowed gun-rights advocate, declared, "There is no proof to support the idea that concealed-carry permit holders create more violence in society than would otherwise occur; they may, in fact, reduce it."

Goldberg cites evidence from Adam Winkler, a law professor at UCLA, that concealed-carry permit holders actually commit crimes at a lower rate than the general population.

The General Accountability Office recently found that the number of concealed weapon permits in America has surged to approximately 8 million.

According to anti-gun advocates, such an increase in guns would cause a cause a corresponding increase in gun-related violence or crime. In fact, the opposite is true. The FBI reported this year that violent crime rates in the U.S. are reaching historic lows.

This comes in spite of the fact that the federal assault weapons ban expired in 2004. Supporters of the ban (not including anti-gun groups who thought it didn't go far enough in the first place) claimed that gun crime would skyrocket when the ban was lifted. That wasn't true at all.

In fact, after the expiration of the ban, The New York Times, whose editorial pages are now awash with calls for more gun restrictions, wrote in early 2005, "Despite dire predictions that America's streets would be awash in military-style guns, the expiration of the decade-long assault weapons ban in September has not set off a sustained surge in the weapons' sales, gun makers and sellers say. It also has not caused any noticeable increase in gun crime in the past seven months, according to several city police departments."

But let's take the issue one step further and examine places where all guns, regardless of make or type, are outlawed: gun-free zones. Are gun-free zones truly safe from guns?

John Lott, economist and gun-rights advocate, has extensively studied mass shootings and reports that, with just one exception, the attack on U.S. Rep. Gabrielle Giffords in Tucson, Arizona, in 2011, every public shooting since 1950 in the U.S. in which more than three people have been killed has taken place where citizens are not allowed to carry guns. The massacres at Sandy Hook Elementary, Columbine, Virginia Tech and the Century 16 movie theater in Aurora, Colorado, all took place in gun-free zones.

These murderers, while deranged and deeply disturbed, are not dumb. They shoot up schools, universities, malls and public places where their victims cannot shoot back. Perhaps "gun-free zones" would be better named "defenseless victim zones."

To illustrate the absurdity of gun-free zones, Goldberg dug up the advice that gun-free universities offer to its students should a gunman open fire on campus. West Virginia University tells students to "act with physical aggression and throw items at the active shooter." These items could include "student desks, keys, shoes, belts, books, cell phones, iPods, book bags, laptops, pens, pencils, etc." Such "higher education" would be laughable if it weren't true and funded by taxpayer dollars.

Eliminating or restricting firearms for public self-defense doesn't make our citizens safer; it makes them targets. If we're going to have a national debate about guns, it should be acknowledged that guns, in the hands of qualified and trained individuals subject to background checks, prevent crime and improve public safety.

Document shows CPS had detailed school closing plans

An internal Chicago Public Schools document obtained by the Tribune shows for the first time that the Emanuel administration has weighed how many elementary and high schools to close in which neighborhoods and how to manage the public fallout.

Labeled a "working draft," the Sept. 10 document lays out the costs and benefits of specific scenarios — revealing that the administration has gone further down the path of determining what schools to target than it has disclosed.

While schools are not listed by name, one section of the document contains a breakdown for closing or consolidating 95 schools, most on the West and South sides, as well as targeting other schools to be phased out gradually or to share their facilities with privately run charter schools.

Mayor Rahm Emanuel and his top school leaders have said they are in the early stages of making difficult decisions and that the city cannot afford to keep operating deteriorating schools with dwindling student populations in the face of a billion-dollar budget deficit. The document goes well beyond what the administration has outlined to the public.

Amid a September teachers strike, the Tribune reported that the Emanuel administration was considering plans to close 80 to 120 schools, most in poor minority neighborhoods. Administration officials have repeatedly denied they have such a figure.

"Unless my staff has a hidden drawer somewhere where they've got numbers in there, we don't have a number," schools CEO Barbara Byrd-Bennett said in November.

But the internal document, prepared at a time when school leaders faced a December deadline to make their decisions public, lays out multiple scenarios for closing neighborhood schools and adding privately run charters — a key component of Emanuel's plans for improving public education. Chicago Teachers Union members, aldermen and other charter school critics have accused the administration of favoring the charters while depriving schools in poor neighborhoods of needed improvements.

The document discusses how to deal with public reaction to school closing decisions, with ideas ranging from establishing "a meaningful engagement process with community members" to building a "monitoring mechanism to ensure nimble response to opposition to proposed school actions."

It is unclear how closely the administration is following the ideas in the 3-month-old document; sources told the Tribune the school closing plans are being constantly updated and subsequent proposals have been kept under close wraps.

The detailed document obtained by the Tribune comes from a time when a Chicago teachers strike interrupted the beginning of the school year and Jean-Claude Brizard was still Emanuel's schools chief; the embattled Brizard quit soon after. Byrd-Bennett was a top education official at CPS under Brizard and was named by Emanuel to succeed him.

CPS spokeswoman Becky Carroll said Tuesday that "this plan was proposed by past leadership at CPS and is not supported by CEO Byrd-Bennett."

"In terms of whatever document you have, I don't care when it's dated, as of today there's no list and there's no plan," Carroll said. "Maybe there were multiple, different scenarios passed around at some point, I don't know, but there's no list of schools.

"When CEO Barbara Byrd-Bennett took this position, she made it very clear that we were going to do this differently than how it's been done in the past," which is why she appointed a commission to take public input on school closings, Carroll said.

But under Byrd-Bennett's tenure, at least one of the proposals outlined in the secret document has come to pass — the idea of a five-year moratorium on further school closings after this school year.

First mention: The September document raises the idea of a moratorium that would extend beyond Emanuel's first term in office as part of the rollout of school closings. But the mayor's first public mention of a moratorium came in November, when he offered it as a sweetener that helped persuade state lawmakers to extend the December deadline for announcing school closings to March.

Critics called the delay a ploy to give opponents less time to organize against the closings. But Emanuel said school officials needed the time to gather community input on the "tough choices" about school closings.

Byrd-Bennett said her decisions on what schools to close won't come until after she receives recommendations from the commission she created. The Tribune reported last week that the commission chairman doesn't plan on issuing recommendations until days before the March 31 deadline for announcing school closings — and even then, there are no plans for the commission to identify individual schools.

While CPS has not released a list of schools to close, it has made publicly available a breakdown of how much a building is used, performance levels per school and how expensive the facility is to keep open. School officials have said underenrollment is a key factor in school closing decisions this year. The school system recently released a list of about 300 "underutilized" schools — nearly half the district — that have dwindling student populations.

But the document obtained by the Tribune contains clues as to how the administration could make those decisions.

Closing breakdown: The most stark page in the document is a graphic that breaks down the 95 schools that could be closed in each of CPS' 19 elementary and high school networks.

Park set to win South Korean presidential election

SEOUL (Reuters) - The daughter of a former military ruler took a commanding lead in South Korea's presidential election on Wednesday, putting her on track to become the country's first woman head of state.

A win for 60-year old conservative Park Geun-hye would see her return to the presidential palace where she served as her father's first lady in the 1970s, after Park's mother was assassinated by a North Korean-backed gunman.

With more than 70 percent of the votes counted, Park led with 51.6 percent to 48 percent for her left-wing challenger, human rights lawyer Moon Jae-in.

Her raucous, jubilant supporters braved sub-zero temperatures to chant her name and wave South Korean flags outside her house.

An elated Park reached into the crowd to grasp hands.

Park will take office for a mandatory single, five-year term in February and will face an immediate challenge from a hostile North Korea and have to deal with an economy in which annual growth rates have fallen to about 2 percent from an average of 5.5 percent in the past 50 years.

She is unmarried and has no children, saying that her life will be devoted to her country.

The legacy of her father, Park Chung-hee, who ruled for 18 years and transformed the country from the ruins of the 1950-53 Korean War into an industrial power-house still divides Koreans.

For many conservatives, he is South Korea's greatest president and the election of his daughter would vindicate his rule. His opponents dub him a "dictator" who trampled on human rights and stifled dissent.

"I trust her. She will save our country," said Park Hye-sook, 67, who voted in an affluent Seoul district, earlier in the day.

"Her father ... rescued the country," said the housewife and grandmother, who is no relation to the candidate.

For younger people, the main concern is the economy and the creation of well-paid jobs in a country where income inequalities have grown in recent years.

"Now a McDonald's hamburger is over 5,000 Korean won ($4.66) so you can't buy a McDonald's burger with your hourly pay. Life is hard already for our two-member family but if there were kids, it would be much tougher," said Cho Hae-ran, 41, who is married and works at a trading company.

Park has spent 15 years in politics as a leading legislator in the ruling Saenuri party, although her policies are sketchy.

She has a "Happiness Promotion Committee" and her campaign was launched as a "National Happiness Campaign", a slogan she has since changed to "A Prepared Woman President".

She has cited former British Prime Minister Margaret Thatcher, a tough proponent of free markets, as her role model as well as Angela Merkel, the conservative German chancellor who is Europe's most powerful leader.

NEGOTIATE WITH NORTH

One of those who voted on Wednesday was Shin Dong-hyuk, a defector from North Korea who is the only person known to have escaped from a slave labor camp there.

He Tweeted that he was voting "for the first time in my life", although he didn't say for whom.

Park has said she would negotiate with Kim Jong-un, the youthful leader of North Korea who recently celebrated a year in office, but wants the South's isolated and impoverished neighbor to give up its nuclear weapons program as a precondition for aid, something Pyongyang has refused to do.

The two Koreas remain technically at war after an armistice ended their conflict. Kim Il Sung, the grandfather of the North's current leader, ordered several assassination attempts on Park's father, one of which resulted in her mother being shot to death in 1974.

Park herself met Kim Jong-un's father, the late leader Kim Jong-il, and declared he was "comfortable to talk to" and he seemed to be someone "who would keep his word".

The North successfully launched a long-range rocket last week in what critics said was a test of technology for an intercontinental ballistic missile and has recently stepped up its attacks on Park, describing her as holding a "grudge" and seeking "confrontation", code for war.

Park remains a firm supporter of a trade pact with the United States that and looks set to continue the free-market policies of her predecessor, although she has said she would seek to spread wealth more evenly.

The biggest of all the chaebol, Samsung Group, which produces the world's top selling smartphone as well as televisions, computer chips and ships, has sales equivalent to about a fifth of South Korea's national output.
