Pearl Jam announces July concert at Wrigley Field

Pearl Jam (January 22, 2013)

Tribune staff report

8:21 a.m. CST, January 23, 2013

Pearl Jam will be playing at Wrigley Field Friday, July 19, the band confirmed this morning.

The band tweeted out, "IT'S OFFICIAL: Pearl Jam will be playing at Wrigley Field. Will you be there?" The show will be called “An Evening With Pearl Jam," with no opening act.

Tickets will go on sale Feb. 9 at 10 a.m. central, according to concert promoter Live Nation. Tickets will be available at www.tickets.com or by calling 1-800-THE-CUBS. Tickets will not be available at the Wrigley Field Box Office.

Pearl Jam and the Cubs haven't been very subtle about the possibility of the iconic band playing a concert at Wrigley Field in 2013.

Tuesday afternoon, both the Cubs and Pearl Jam Tweeted pictures of the field at Wrigley, with a full concert setup. The band's Tweet, featuring the "stay tuned" hashtag, also included a "looking good" reference to the Wrigley image.

The Cubs also played a role in the suspense, sending out a Tweet that included "Ten," and a repeat of the "stay tuned" hashtag. There was also a link to a photo of a Ron Santo Cubs jersey (No. 10), the parallel being that “Ten” is also the title of Pearl Jam’s first album.

The band also announced a July 16 date in London, Ontario.

Cameron promises Britons straight choice on EU exit

LONDON (Reuters) - Prime Minister David Cameron promised on Wednesday to give Britons a referendum choice on whether to stay in the European Union or leave if he wins an election in 2015, placing a question mark over Britain's membership for years.

Cameron ended months of speculation by announcing in a speech the plan for a vote sometime between 2015 and the end of 2017, shrugging off warnings that this could imperil Britain's economic prospects and alienate its biggest trading partner.

He said the island nation, which joined the EU's precursor European Economic Community 40 years ago, did not want to retreat from the world, but public disillusionment with the EU was at "an all-time high".

"It is time for the British people to have their say. It is time for us to settle this question about Britain and Europe," Cameron said. His Conservative party will campaign for the 2015 election promising to renegotiate Britain's EU membership.

"When we have negotiated that new settlement, we will give the British people a referendum with a very simple in or out choice to stay in the European Union on these new terms; or come out altogether. It will be an in-out referendum."

The speech firmly ties Cameron to an issue that was the bane of a generation of Conservative leaders. In the past, he has avoided partisan fights over Europe, the undoing of the last two Conservative prime ministers, John Major and Margaret Thatcher.

Britain would seek to claw back powers from Brussels, he said, a proposal that will be difficult to sell to other European countries. London will do an "audit" to determine which powers Brussels has that should be delegated to member states.

Sterling fell to its lowest in nearly five months against the dollar on Wednesday as Cameron was speaking.

The response from EU partners was predictably frosty. French Foreign Minister Laurent Fabius quipped: "If Britain wants to leave Europe we will roll out the red carpet for you," echoing Cameron himself, who once used the same words to invite rich Frenchmen alienated by high taxes to move to Britain.

German Foreign Minister Guido Westerwelle said his country wanted Britain to remain a full EU member, but London could not expect to pick and choose the aspects of membership it liked.

Business leaders have warned that the prospect of years of doubt over Britain's EU membership would damage the investment climate.

"Having a referendum creates more uncertainty and we don't need that," Martin Sorrell, chief executive of advertising giant WPP, told the World Economic Forum in Davos.

"This is a political decision. This is not an economic decision. This isn't good news. You added another reason why people will postpone investment decisions."

The speech also opens a rift with Cameron's junior coalition partners, the Liberal Democrats. Their leader, Deputy Prime Minister Nick Clegg, said the plan would undermine a fragile economic recovery.

And even allies further afield are wary: the United States has said it wants Britain to remain inside the EU with "a strong voice".

EUROSCEPTICS THRILLED

Cameron has been pushed into taking such a strong position in part by the rise of the UK Independence Party, which favors complete withdrawal from the EU and has climbed to third in opinion polls, mainly at the expense of the Conservatives.

"All he's trying to do is to kick the can down the road and to try and get UKIP off his back," said UKIP leader Nigel Farage.

Eurosceptics in Cameron's party were thrilled by the speech. Conservative lawmaker Peter Bone called it "a terrific victory" that would unify 98 percent of the party. "He's the first prime minister to say he wants to bring back powers from Brussels," Bone told Reuters. "It's pretty powerful stuff".

Whether Cameron will ever hold the referendum remains as uncertain as the Conservatives' chances of winning the next election in 2015.

They trail the opposition Labour party in opinion polls, and the coalition government is grappling with a stagnating economy as it pushes through public spending cuts to reduce Britain's large budget deficit.

Cameron said he would prefer Britain, the world's sixth biggest economy, to remain inside the 27-nation EU. As long as he secured the reforms he wants, he would campaign for Britain to stay inside the EU "with all my heart and soul".

But he also made clear he believed the EU must be radically reformed. It was riskier to maintain the status quo than to change, he said.

"The biggest danger to the European Union comes not from those who advocate change, but from those who denounce new thinking as heresy," he said.

"WAFER THIN" CONSENT

The euro zone debt crisis was forcing the bloc to change, and Britain would fight to make sure new rules were fair to countries that didn't use the common currency, he said. Britain is the largest of the 10 EU members that do not use the euro.

Democratic consent for the EU in Britain was now "wafer thin", he said, reflecting the results of opinion polls that show a slim majority would vote to leave the bloc.

"Some people say that to point this out is irresponsible, creates uncertainty for business and puts a question mark over Britain's place in the European Union," said Cameron. "But the question mark is already there: ignoring it won't make it go away."

Asked after the speech whether other EU countries would agree to renegotiate Britain's membership, Cameron said he was an optimist and that there was "every chance of success."

"I want to be the prime minister who confronts and gets the right answer for Britain on these kind of issues," he said.

It is nearly 40 years since British voters last had a say in a referendum on Britain's membership of the European club. A 1975 vote saw just over 67 percent opt to stay inside with nearly 33 percent wanting to leave.

Wall Street opens flat as investors eye earnings

NEW YORK (Reuters) - U.S. stocks were little changed near five-year highs on Tuesday as investors held back from making large bets ahead of earnings from key tech companies.

Both the Dow and S&P 500 closed at their highest levels so far in this earnings season, with the gains largely coming on better-than-expected results. But despite bullish statements from major companies, many investors are worried economic uncertainty in the fourth quarter hurt earnings and revenues.

Weaker-than-expected economic data had little impact on stocks. Existing-home sales unexpectedly fell in December, dropping 1 percent, according to the National Association of Realtors. Analysts were looking for a rise of 1.2 percent.

Recently Apple Inc and Intel Corp gave weak outlooks, calling the tech sector' outlook into question. Three tech companies are due to report after the market's close: Google Inc, International Business Machines and Texas Instruments.

"Markets are quiet today with many investors taking a wait-and-see approach to tonight's tech earnings," said Douglas DePietro, managing director at Evercore Partners in New York. "There's still room for us to rise from here, but right now most of the action is in specific stocks."

Four Dow components reported early on Tuesday, and three rose on the results. Insurer Travelers Cos was the stand-out, climbing 3.4 percent to $78.90 as the S&P 500's biggest percentage gainer after it forecast higher premiums across its business.

DuPont, the largest U.S. chemical company by market capitalization, reported revenue that was ahead of Wall Street expectations, while Verizon Communications Inc also posted revenue that beat forecasts.

Shares of DuPont were up 0.6 percent at $47.24 while Verizon rose 0.3 percent to $42.67.

On the downside, Johnson & Johnson, the diversified health company, fell 0.5 percent to $72.87 after forecasting 2013 earnings below expectations.

The Dow Jones industrial average was down 6.07 points, or 0.04 percent, at 13,643.63. The Standard & Poor's 500 Index was down 1.56 points, or 0.10 percent, at 1,484.42. The Nasdaq Composite Index was down 2.52 points, or 0.08 percent, at 3,132.19.

Monday was a market holiday for Martin Luther King Jr. Day in the United States. President Barack Obama at his inauguration for a second term on Monday called for aggressive action on climate change, economic equality and the federal budget.

Markets have recently been pressured by uncertainty stemming from Washington about the federal debt limit and spending cuts that could hamper U.S. growth.

Republican leaders in the House of Representatives said they aim to pass on Wednesday a nearly four-month extension of the U.S. debt limit, allowing the government to borrow enough to meet its obligations during that period.

Overall, S&P 500 fourth-quarter earnings rose 2.5 percent, according to Thomson Reuters data.

U.S. shares of Research in Motion jumped 8.2 percent to $17.13 a day after its chief executive said the company may consider strategic alliances with other companies after the launch of devices powered by RIM's new BlackBerry 10 operating system.

Jim, John Harbaugh ready for rematch at Super Bowl

SANTA CLARA, Calif. (AP) — Jim and John Harbaugh have exchanged a handful of text messages, and plan to leave it at that. No phone conversations necessary while the season's still going. No time for pleasantries, even for the friendly siblings.

There is work to be done to prepare for the Super Bowl, prepare for each other, prepare for a history-making day already being widely hyped as "Harbowl" or "Superbaugh" depending which nickname you prefer.

"It doesn't matter who the coach is, what relationship you have with the person on the other side," 49ers coach Jim Harbaugh said so matter-of-factly Monday afternoon.

Their parents sure aren't picking sides for the Feb. 3 matchup in New Orleans.

These days, the Harbaughs' longtime coaching father, Jack, stays away from game-planning chatter or strategy sessions with his Super Bowl-bound coaching sons. Baltimore's John Harbaugh and little brother Jim have been doing this long enough now to no longer need dad's input.

Yet, they still regularly seek it. And, their father does offer one basic mantra: "Get ahead, stay ahead."

"Probably the greatest advice that I've ever been given and the only advice that I've ever found to be true in all of coaching, I think we mentioned it to both John and Jim ... the coaching advice is, 'Get ahead, stay ahead,'" Jack Harbaugh said.

"If I'm called upon, I'll repeat that same message."

His boys still call home regularly to check in with the man who turned both on to the coaching profession years ago, and the mother who has handled everything behind the scenes for decades in a highly competitive, sports-crazed family — with all the routine sports clichés to show for it.

The Harbaugh brothers will become the first siblings to square off from opposite sidelines when their teams play for the NFL championship at the Superdome.

Not that they're too keen on playing up the storyline that has no chance of going away as hard as they try.

"Well, I think it's a blessing and a curse," Jim Harbaugh said Monday. "A blessing because that is my brother's team. And, also, personally I played for the Ravens. Great respect for their organization. ... The curse part would be the talk of two brothers playing in the Super Bowl and what that takes away from the players that are in the game. Every moment that you're talking about myself or John, that's less time that the players are going to be talked about."

Both men love history, just not the kind with them making it.

"I like reading a lot of history ... I guess it's pretty neat," John Harbaugh offered Monday. "But is it really going to be written about? It's not exactly like Churchill and Roosevelt or anything. It's pretty cool, but that's as far as it goes."

Nice try, guys.

John watched the end of Jim's game from the field in Foxborough, Mass., as Baltimore warmed up for the AFC championship game. Jim called his sister's family from the team plane before takeoff after a win at Atlanta and asked how his big brother's team was doing against New England.

The improbable Super Bowl features a set of brothers known around the NFL as fierce competitors unafraid to make a bold move during the season. Unafraid to upset anyone who stands in their way.

In fact, each one made a major change midseason to get this far — John fired his offensive coordinator, while Jim boosted his offense with a quarterback switch from Alex Smith to Colin Kaepernick.

Leading up to Sunday's games, parents Jack and Jackie said they would wait to decide whether to travel to New Orleans if both teams advanced or stick to what has been working so well — watching from the comfort of their couch in Mequon, Wis.

"We enjoy it very much. We get down in our basement, turn on the television and just have a fantastic day watching outstanding football," Jack said last week. "We share our misery with no one but ourselves. Not only the misery, but the ups and downs, the ins and outs of an outstanding professional game."

And, no, the Harbaughs weren't looking ahead to a potential big trip to the Big Easy.

Jack insists his wife is quick to pull out that old sports cliche: "It's one game at a time. I think it's very appropriate," he said.

Jim figures they won't possibly miss this history-making game.

"I think they'll be there," he said with a smile.

The brothers, separated in age by 15 months, have taken different paths to football's biggest stage — years after their intense games of knee football at the family home. They tried to beat each other at cards, or whatever other game it was at the time. Sometimes, they tried to beat each other up. Sister, Joani Crean, often got in on the fun, too.

The 49-year-old Jim never reached a Super Bowl, falling a last-gasp pass short during a 15-year NFL career as a quarterback. The 50-year-old John never played in the NFL.

Still, both will tell you, "Who's got it better than us? No-body!" — one catchphrase they got from their dad.

"We can't put into words what it means to see John and Jim achieve this incredible milestone," their brother-in-law, Indiana basketball coach Tom Crean, said on Twitter. "We talked to Jim (before) his team plane left. All he wanted to know was how was John doing? How were they playing? One incredible family who puts the care, well-being and love for each other at the forefront like most families do. Again, we are very proud of them. Going to be exciting to watch it unfold."

John worked his way up from the bottom of the coaching ranks, while Jim was the star college quarterback at Michigan, a first-round draft pick and eventual Pro Bowler who made coaching his career once he retired.

John already has the one-up, while Jim's team is the early favorite. John's Ravens beat the 49ers 16-6 on Thanksgiving night 2011, in Jim's rookie season as an NFL coach — though both know that means nothing now.

"I just want everybody to know, that was a four-day deal and every story has been told," John said. "We're not that interesting. There's nothing more to learn. The tape across the middle of the room story, OK, you got it? It's OK. It was just like any other family, really. I really hope the focus is not so much on that. We get it, it's really cool and it's exciting and all that."

Said Jim, "Completely new business."

In spite of his efforts to avoid the topic, Jim did take the opportunity to express how proud he is of John.

"He's a great football coach, a real grasp of all phases — offense, defense, special teams. I think he could coordinate at least two of those phases and do it as well as anyone in the league," Jim said. "I've got half the amount of coaching experience he does. Again, it's not about us. I keep coming back to that. I'm really proud of my brother. I love him. That's the blessing part, that this is happening to him."

And, fittingly for the big brother, John feels the exact same way.

Defterios: What keeps Davos relevant

STORY HIGHLIGHTS

• Since the late 20th Century, the ski resort of Davos has been synonymous with the World Economic Forum

Davos (CNN) -- Veterans of Davos often refer to nature's awe-inspiring work as the Magic Mountain.

The name comes from an early 20th century novel by Thomas Mann -- reflecting on life in an alpine health retreat, and the mystery of time in this breath-taking setting.

Read more from John Defterios: Why Egypt's transition is so painful

Since the late 20th century, this ski resort has been synonymous with the World Economic Forum, which represents networking on its grandest scale.

This year nearly 40 world leaders -- a record for this annual meeting -- 2000 plus executives and it seems an equal number of people in the media, like yours truly, are in pursuit of them all. The setting is certainly more chaotic then a decade ago. The agendas of the Fortune 500 chief executives are to filled with bi-lateral meetings and back door briefings to allow for the spontaneity that made this venue unique.

Davos gets ready for leaders' gathering

HIDE CAPTION

I first came to Davos as a relatively junior correspondent in 1990, two months after the fall of the Berlin Wall. It was arguably then, after nearly two decades in the conference business, when the forum became a fixture on the global calendar.

Quest: U.S. economy to dominate Davos 2013

I can remember, quite vividly, working out of a bunker (like we do today) in the Davos Congress Centre. West German Chancellor Helmut Kohl sat side-by-side with his East German counterpart Hans Modrow. That meeting before the global community helped set the stage for monetary union, a huge unification fund for what became Eastern Germany and shortly thereafter German elections.

The early 90s at Davos were dominated by European reconstruction after the fall of communism. Former party bosses came to the forum to convince business leaders that a transition to market economics could be delivered. Boris Yeltsin made his Davos appearance during that chaotic transition from the USSR to today's Russia.

Davos 2013: New year, same old problems?

In 1992, Chinese Premier Li Peng used the setting here in the Alps to articulate plans for the country's economic opening up to the world. Not by chance, the architect of Washington's engagement with Beijing, the former U.S. Secretary of State Henry Kissinger also took a high profile that year.

Again only two years later in 1994, Yasser Arafat and Shimon Peres walked hand in hand on stage, holding a public dialogue leading up to the creation and recognition of the Palestinian Authority.

The World Economic Forum, as the saying goes, was positioned to be in the right place at the right time. While the author of the Magic Mountain talked about the complexity of time around World War I, in the 1990s time was compressed here.

The fall of communism, the lowering of global trade barriers, the opening up of China, the removal of apartheid in South Africa and the proliferation of the internet all unfolded in that decade.

Interactive: How's your economic mood?

As those events came together, so too did the major players as they made the journey to Davos. Michael Bloomberg, evolving as a global name in financial data and now the Mayor of New York City, sat alongside Microsoft CEO Bill Gates. U.S. President Bill Clinton outlined his party's historic move to the political center before a packed audience of global business executives.

To spice things up, rock stars and actors, as they became activists, chose the Davos platform: Bono, Richard Gere, Sharon Stone, Brad and Angelina would have the wealthiest and most powerful corporate titans freeze in their tracks.

Earlier this week, I walked into the main plenary hall as workers put the final touches on the stage and lighting. It is a venue which has welcomed countless political leaders and business executives, during internet booms and banking busts, in the midst of a Middle East crisis and even during the lead up to two Gulf Wars.

But that inter-play between geo-politics and business -- during the best and worst of times -- is what keeps the forum relevant. It allows this setting at the base of the Magic Mountain to endure and recreate something unique during what Mann rightly described as the ongoing complexity of our times.

Single-digit freeze continues; wind chills at dangerous levels

Chicago's morning weather forecast. ( WGN - Chicago)

Brace yourself and bundle up.

After a night when temperatures dipped to the low single digits, "they're not going to move a whole lot today," said Mark Ratzer, a meteorologist with the National Weather Service.

Temperatures may not break 10 degrees today, Ratzer says, and if they do, it won't be by more than a degree or two. A wind chill advisory issued Monday remains in effect until 10 a.m. this morning.

At 8 a.m., it was minus 1 degree at O'Hare International Airport, with a wind chill of minus 14. This is the first time since Feb. 10, 2011 that a subzero temperature has been recorded in Chicago. The streak of 711 consecutive days without a subzero temperature was the fourth longest on record, according to Richard Castro, also a meteorologist at the weather service.

If there's good news, it's that the wind won't be quite as strong as it was Monday when wind chills plummeted into the negative teens.

It won't be as cold as it was on Jan. 22, 1936, when a low temperature of 17 degrees below zero set Chicago's all-time record.

That's about where the good news stops. The cold will linger for several days, and temperatures are not expected to top 32 degrees until early next week, Ratzer said.

The overnight low of 4 degrees was the coldest since Feb. 10, 2011, when aided by a heavy snow cover, temperatures dipped to 9 below zero.

Over a 30-year period, the average temperature high for Jan. 22 is 31 degrees and the average low is 16.

Authorities reported no overnight deaths from the cold, though today's temperatures remain dangerous for anyone spending prolonged periods outdoors.

At least seven people in Cook County have died from causes related to the cold this season.

Israel goes to polls, set to re-elect Netanyahu

JERUSALEM (Reuters) - Israelis voted on Tuesday in an election that is expected to hand hawkish Prime Minister Benjamin Netanyahu a third term, opening the way for a showdown with Iran and bolstering opponents of Palestinian statehood.

However, Netanyahu's own Likud party, running alongside the ultra-nationalist Yisrael Beitenu group, looks set to have fewer seats than in the previous parliament, with opinion polls showing a surge in support for the far-right Jewish Home party.

Political sources said Netanyahu, concerned by his apparent fall in popularity, might approach center-left parties after the ballot in an effort to broaden his coalition and present a more moderate face to Washington and other concerned allies.

"We want Israel to succeed, we vote Likud-Beitenu ... The bigger it is, the more Israel will succeed," Netanyahu said after voting alongside his wife and two sons.

Some 5.66 million Israelis are eligible to cast a ballot, with polling stations closing at 10 p.m.. Full results are due by Wednesday morning, opening the way for coalition talks that could take several weeks.

By 2 p.m., the Israeli election committee said turnout was 38.3 percent, up from 34 percent at the same time in 2009 and the highest level since 1999. Ahead of the ballot, analysts had speculated that high turnout would benefit center-left parties that have sometimes struggled to motivate their voter base.

The lackluster election campaign failed to focus on any single issue and with a Netanyahu victory predicted by every opinion poll, the two main political blocs seemed to spend more time on internal feuding than confronting each other.

"There is a king sitting on the throne in Israel and I wanted to dethrone him, but it looks like that won't happen," said Yehudit Shimshi, a retired teacher voting in central Israel in balmy winter weather that drew out the electorate.

No Israeli party has ever secured an absolute majority, meaning that Netanyahu, who says that dealing with Iran's nuclear ambitions is his top priority, will have to bring various allies on board to control the 120-seat Knesset.

The former commando has traditionally looked to religious, conservative parties for backing and is widely expected to seek out the surprise star of the campaign, self-made millionaire Naftali Bennett, who heads the Jewish Home party.

Bennett has ruled out any peace pact with the Palestinians and calls for the annexation of much of the occupied West Bank.

His youthful dynamism has struck a chord amongst Israelis, disillusioned after years of failed peace initiatives, and has eroded Netanyahu's support base.

The Likud has also shifted further right in recent months, with hardline candidates who reject the so-called two-state solution dominating the top of the party list.

"TRENDY PARTIES"

Surveys suggest Bennett may take up to 14 seats, many at the expense of Likud-Beitenu, which was projected to win 32 in the last round of opinion polls published on Friday - 10 less than the two parties won in 2009 when they ran separate lists.

Acknowledging the threat, Netanyahu's son Yair urged young Israelis not to abandon the old, established Likud.

"Even if there are more trendy parties, there is one party that has a proven record," he said on Tuesday.

Amongst the new parties standing for the first time in an election were Yesh Atid (There is a Future), a centrist group led by former television host Yair Lapid, seen winning 13 seats.

"All our lives we voted Likud, but today we voted for Lapid because we want a different coalition," said Ahuva Heled, 55, a retired teacher voting with her husband north of Tel Aviv.

Lapid has not ruled out joining a Netanyahu cabinet, but is pushing hard for ultra-Orthodox Jews to do military service - a demand fiercely rejected by some allies of the prime minister.

Israel's main opposition party, Labour, which is seen capturing up to 17 seats, has already ruled out a repeat of 2009, when it initially hooked up with Netanyahu, promising to promote peace negotiations with the Palestinians.

U.S.-brokered talks collapsed just a month after they started in 2010 following a row over settlement building, and have lain in ruins ever since. Netanyahu blamed the Palestinians for the failure and says his door remains open to discussions.

Palestinian President Mahmoud Abbas says he won't return to the table unless there is a halt to settlement construction.

That looks unlikely, with Netanyahu approving some 11,000 settler homes in December alone, causing further strains to his already notoriously difficult relations with U.S. President Barack Obama, who was sworn in for a second term on Monday.

IRAN THREAT

Tuesday's vote is the first in Israel since Arab uprisings swept the region two years ago, reshaping the Middle East.

Netanyahu has said the turbulence - which has brought Islamist governments to power in several countries long ruled by secularist autocrats, including neighboring Egypt - shows the importance of strengthening national security.

If he wins on Tuesday, he will seek to put Iran back to the top of the global agenda. Netanyahu has said he will not let Tehran enrich enough uranium to make a single nuclear bomb - a threshold Israeli experts say could arrive as early as mid-2013.

Iran denies it is planning to build the bomb, and says Israel, widely believed to have the only nuclear arsenal in the Middle East, is the biggest threat to the region.

The issue has barely registered during the election campaign, with a poll in Haaretz newspaper on Friday saying 47 percent of Israelis thought social and economic issues were the most pressing concern, against just 10 percent who cited Iran.

One of the first problems to face the next government, which is unlikely to take power before the middle of next month at the earliest, is the stuttering economy.

Data last week showed the budget deficit rose to 4.2 percent of gross domestic product in 2012, double the original estimate, meaning spending cuts and tax hikes look certain.

NASA Eyes ‘Hedgehog’ Invasion of Mars Moon Phobos

A daring, “Angry Birds”-like NASA mission could bombard a Martian moon with robotic “hedgehog” probes in the next few decades, scientists say.

The space hedgehogs are actually small, spiky, spherical rovers that form part of a novel mission idea called Phobos Surveyor. The rovers would take advantage of the low gravity on the Mars moon Phobos, its sister moon Deimos, or asteroids in the solar system. Engineers have designed the devices to work in concert with a nearby mother ship.   

The hedgehogs would work well in the low gravity of the 16-mile-wide (27 kilometers) Phobos, a force 1,000 times weaker than the gravity on Mars itself, where NASA’s Curiosity and Opportunity rovers currently explore, said researcher Marco Pavone of Stanford University. Gravity on Mars is about one-third that of the Earth.

“The problem with [conventional] rovers is, in low gravity, you don’t have any traction. That means your wheels spin and you do not move,” said Pavone, who developed the hedgehog mission concept. [Boldest Mars Missions in History]

Robot hedgehogs in space

Instead of using wheels to move across a planetary surface, however, the hedgehogs would use internal, rotating discs. Plans call for three discs encased in each hedgehog. Each spacecraft would measure about 2 feet (0.6 meters) in diameter, and NASA has already built a prototype version, researchers said.

The three discs inside a hedgehog point in different directions, giving controllers the ability to move the devices with precision, Pavone said. Slightly speeding up the discs can send the hedgehogs tumbling, and a quick spin can make the hedgehog hop to a nearby location, he added.

To get to Phobos, the hedgehogs will potentially hitch a ride inside the proposed Phobos Surveyor, which could be a Discovery-class NASA mission with a cost of about $ 250 million and a streamlined development schedule to meet its science goals. At best, the Phobos mission could launch in 10 to 20 years, but that assumes the concept is approved and funded.

The exploitation of inertial motion is not entirely new to space exploration, as the Japanese Space Agency’s Hayabusa spacecraft pursued a similar idea. That craft released a small lander while above the asteroid Itokawa.

Dubbed MINERVA (for MIcro/Nano Experimental Robot Vehicle for Asteroid), Hayabusa’s tiny lander was supposed to bounce on the asteroid using rotating actuators. But it never made it to the surface.

NASA’s hedgehog would have the ability to not only hop, but also tumble, which would make it potentially a more versatile lander than MINERVA if it were to arrive on Phobos, the research team said.

Separately, NASA’s Jet Propulsion Laboratory has developed a nanorover concept, which envisions a rover that can both hop and roll. This device was planned for a space mission, but that mission never got off the ground.

Probing Phobos’ origins

Pavone’s team has already built two versions of the hedgehogs, but the rovers still require several design changes before they could make it to space. The researchers also plan further testing, including flying the hedgehogs on parabola flights that simulate low gravity, just to see how they behave.

Pavone said he hopes the hedgehogs will help solve a long-standing mystery: Did Phobos form at the same time as Mars, or is it an asteroid pulled in by the Red Planet’s gravity?

“By providing answers to this equation, it will be possible to calibrate this model … for [other] asteroids through the solar system,” Pavone said.

According to the plan, five or six hedgehogs could make the trip to Phobos, which would take about two years. The Phobos Surveyor mother ship could then spend a few months analyzing potential landing sites before releasing the hedgehogs, one at a time.

The mother ship would stay in orbit and map the surface’s composition, though scientists are still discussing which actual instruments to send aboard the craft. The ship could also relay the hedgehogs’ findings back to Earth.

The Phobos Surveyor study is funded under the NASA Innovative Advanced Concepts Program and includes contributors from NASA’s Jet Propulsion Laboratory, the Massachusetts Institute of Technology and Stanford.

How Obama made opportunity real

STORY HIGHLIGHTS

• LZ Granderson: Specifics of Obama's first term may not be remembered


• He says his ability to win presidency twice is unforgettable


• Granderson: Obama, the first black president, makes opportunity real for many


• He says it makes presidency a possibility for people of all backgrounds

(CNN) -- In his first term, President Barack Obama signed 654 bills into law, the Dow Jones Industrial Average increased by about 70% and the national debt by $5.8 trillion.

And in 10 years -- maybe less -- few outside of the Beltway will remember any of that. That's not to suggest those details are not important. But even if all of his actions are forgotten, Obama's legacy as the first black president will endure.

And even though this is his second term and fewer people are expected to travel to Washington this time to witness the inauguration, know that this moment is not any less important.

For had Obama not been re-elected, his barrier-breaking election in 2008 could have easily been characterized as a charismatic politician capturing lightning in a bottle. But by becoming the first president since Dwight Eisenhower to win at least 51% of the vote twice, Obama proved his administration was successful.

And not by chance, but by change.

A change, to paraphrase Martin Luther King Jr., that was not inevitable but a result of our collective and continuous struggle to be that shining city on a hill of which President Ronald Reagan spoke so often.

Best of 2013 inauguration

For much of this country's history, being a white male was a legal prerequisite to being president. Then it was accepted as a cultural norm. Because of that, we could not be the country we set out to be.

But today, somewhere in the Midwest, there is a little Asian-American girl with the crazy idea she could be president one day, and because of Obama, she knows that idea is not very crazy at all.

That's power -- the kind of power that can fade urgent numbers and debates of the day into the background of history.

Gergen: Obama 2.0 version is smarter, tougher

Few remember the number of steps Neil Armstrong took when he landed on the moon, but they remember he was the first human being who stepped on the moon. Few can tell you how many hits Jackie Robinson had in his first Major League Baseball game, but they know he broke baseball's color barrier. Paying homage to a person being first at something significant does not diminish his or her other accomplishments. It adds texture to the arc of their story.

I understand the desire not to talk about race as a way of looking progressive.

But progress isn't pretending to be color blind, it's not being blinded by the person's color.

Or gender.

Or religion.

Or sexual orientation.

Somewhere in the South, there is an openly gay high schooler who loves student government and wants to be president someday. And because of Obama, he knows if he does run, he won't have to hide.

That does not represent a shift in demographics, but a shift in thought inspired by a new reality. A reality in which the president who follows Obama could be a white woman from Arkansas by way of Illinois; a Cuban-American from Florida; or a tough white guy from Jersey. Or someone from an entirely different background. We don't know. Four years is a long time away, and no one knows how any of this will play out -- which I think is a good thing.

For a long time, we've conceived of America as the land of opportunity. Eight years ago, when it came to the presidency, that notion was rhetoric. Four years ago, it became a once in a lifetime moment. Today, it is simply a fact of life.

Ten years from now, we may not remember what the unemployment rate was when Obama was sworn in a second time, but we'll never forget how he forever changed the limits of possibility for generations to come.

Somewhere out West, there is an 80-year-old black woman who never thought she'd see the day when a black man would be elected president. Somehow I doubt Obama's second inauguration is less important to her.

Union: Deal reached between Grayslake schools, teachers

Staff report

8:55 a.m. CST, January 21, 2013

School and union officials in north suburban Grayslake have reached a tentative agreement that will end the teacher's strike there, the union and school district announced Monday.

After negotiations failed to yield an agreement on a new contract, the teachers' union called for a strike that began last Wednesday.

Early this morning, officials from Community Consolidated School District 46 and the teachers' union issued a brief joint statement announcing a tentative deal, according to Dave Comerford, a spokesman for the teachers union. The school district said it would be a two-year contract.

Schools will reopen Tuesday, according to the statement shared by Comerford, but the agreement remains subject to union ratification and Board of Education approval.

The school district announced the tentative agreement on its web site, saying that classes at the district's schools will resume Tuesday after the already scheduled day off today for the Martin Luther King holiday.

On the website, the district said it would not share details of the contract until it is ratified by both the union and the school board.
