USA Locates & Kills Bin Laden




The White House

Office of the Press Secretary

For Immediate Release May 02, 2011 Press Briefing by Senior Administration Officials on the Killing of Osama bin Laden
Via Conference Call


12:03 A.M. EDT

MR. VIETOR: Thank you, everyone, for joining us, especially so late. We wanted to get you on the line quickly with some senior administration officials to talk about the operation today regarding Osama bin Laden. And with that I’ll turn it over to our first senior administration official.

SENIOR ADMINISTRATION OFFICIAL: Thanks for joining us, everybody, at this late hour. It’s much appreciated. From the outset of the administration, the President has placed the highest priority in protecting the nation from the threat of terrorism. In line with this, we have pursued an intensified, targeted, and global effort to degrade and defeat al Qaeda. Included in this effort has been a relentless set of steps that we’ve taken to locate and bring Osama bin Laden to justice. Indeed, in the earliest days of the administration, the President formally instructed the intelligence community and his counterterrorism advisors to make the pursuit of Osama bin Laden, as the leader of al Qaeda, as a top priority.

In the beginning of September of last year, the CIA began to work with the President on a set of assessments that led it to believe that in fact it was possible that Osama bin Laden may be located at a compound in Pakistan. By mid-February, through a series of intensive meetings at the White House and with the President, we had determined there was a sound intelligence basis for pursuing this in an aggressive way and developing courses of action to pursue Osama bin Laden at this location.

In the middle of March, the President began a series of National Security Council meetings that he chaired to pursue again the intelligence basis and to develop courses of action to bring justice to Osama bin Laden. Indeed, by my count, the President chaired no fewer than five National Security Council meetings on the topic from the middle of March -- March 14th, March 29th, April 12th, April 19th, and April 28th. And the President gave the final order to pursue the operation that he announced to the nation tonight on the morning -- Friday morning of April 29th.

The President mentioned tonight that the pursuit of Osama bin Laden and the defeat of al Qaeda has been a bipartisan exercise in this nation since September 11, 2001, and indeed, this evening before he spoke to the nation, President Obama did speak to President Bush 43 and President Clinton this evening to review with them the events of today and to preview his statement to the nation tonight.

And with that, I’ll turn it over to my colleague to go through some of the details. Thank you.

SENIOR ADMINISTRATION OFFICIAL: As you heard, the President ordered a raid earlier today against an al Qaeda compound in Abbottabad, Pakistan. Based on intelligence collection analysis, a small U.S. team found Osama bin Laden living in a large home on a secured compound in an affluent suburb of Islamabad. The raid occurred in the early morning hours in Pakistan and accomplished its objective. Osama bin Laden is now no longer a threat to America.

This remarkable achievement could not have happened without persistent effort and careful planning over many years. Our national security professionals did a superb job. They deserve tremendous credit for serving justice to Osama bin Laden.

Bin Laden was a sworn enemy of the United States and a danger to all humanity; a man who called for the murder of any American anywhere on Earth. His death is central to the President’s goal of disrupting, dismantling, and ultimately defeating al Qaeda and its violent allies. He was responsible for killing thousands of innocent men and women not only on 9/11, but in the 1998 East Africa embassy bombing, the attack of the USS Cole, and many other acts of brutality.

He was the leader of a violent extremist movement with affiliates across the globe that had taken up arms against the United States and its allies. Bin Laden’s most influential role has been to designate the United States as al Qaeda’s primary target and to maintain organizational focus on that objective. This strategic objective, which was first made in a 1996 declaration of jihad against Americans, was the cornerstone of bin Laden’s message.

Since 9/11, multiple agencies within our intelligence community have worked tirelessly to track down bin Laden, knowing that his removal from al Qaeda would strike a crippling blow to the organization and its militant allies. And last September the President was made aware of a compound in Abbottabad, where a key al Qaeda facilitator appeared to be harboring a high-value target. He received regular intelligence updates, as was just mentioned, on the compound in September, and he directed that action be taken as soon as he concluded that the intelligence case was sufficiently strong. A range of options for achieving the mission were developed, and on Friday he authorized the operation.

Now I’ll turn it to my colleagues to go through the intelligence.

SENIOR ADMINISTRATION OFFICIAL: Thank you. First I want to point out that today’s success was a team effort. It was a model of really seamless collaboration across our government. Since 9/11, this is what the American people have expected of us, and today, in this critical operation, we were able to finally deliver.

The operation itself was the culmination of years of careful and highly advanced intelligence work. Officers from the CIA, the NGA, the NSA all worked very hard as a team to analyze and pinpoint this compound. Together they applied their very unique expertise and capabilities to America’s most vexing intelligence problem, where to find bin Laden.

When the case had been made that this was a critical target, we began to prepare this mission in conjunction with the U.S. military. In the end, it was the matchless skill and courage of these Americans that secured this triumph for our country and the world. I’m very proud of the entire team that worked on this operation, and am very thankful to the President for the courage that he displayed in making the decision to proceed with this operation.

With that, let me turn to my colleague to give you details on the intelligence background.

SENIOR ADMINISTRATION OFFICIAL: Thank you. The bottom line of our collection and our analysis was that we had high confidence that the compound harbored a high-value terrorist target. The experts who worked this issue for years assessed that there was a strong probability that the terrorist that was hiding there was Osama bin Laden.

What I’d like to do is walk you through the key points in that intelligence trail that led us to that conclusion. From the time that we first recognized bin Laden as a threat, the CIA gathered leads on individuals in bin Laden’s inner circle, including his personal couriers. Detainees in the post-9/11 period flagged for us individuals who may have been providing direct support to bin Laden and his deputy, Zawahiri, after their escape from Afghanistan.

One courier in particular had our constant attention. Detainees gave us his nom de guerre or his nickname and identified him as both a protégé of Khalid Sheikh Mohammed, the mastermind of September 11th, and a trusted assistant of Abu Faraj al-Libbi, the former number three of al Qaeda who was captured in 2005.

Detainees also identified this man as one of the few al Qaeda couriers trusted by bin Laden. They indicated he might be living with and protecting bin Laden. But for years, we were unable to identify his true name or his location.

Four years ago, we uncovered his identity, and for operational reasons, I can’t go into details about his name or how we identified him, but about two years ago, after months of persistent effort, we identified areas in Pakistan where the courier and his brother operated. Still we were unable to pinpoint exactly where they lived, due to extensive operational security on their part. The fact that they were being so careful reinforced our belief that we were on the right track.

Then in August 2010, we found their residence, a compound in Abbottabad, Pakistan, a town about 35 miles north of Islamabad. The area is relatively affluent, with lots of retired military. It’s also insolated from the natural disasters and terrorist attacks that have afflicted other parts of Pakistan. When we saw the compound where the brothers lived, we were shocked by what we saw -- an extraordinarily unique compound. The compound sits on a large plot of land in an area that was relatively secluded when it was built. It is roughly eight times larger than the other homes in the area.

When the compound was built in 2005, it was on the outskirts of the town center, at the end of a narrow dirt road. In the last six years, some residential homes have been built nearby. The physical security measures of the compound are extraordinary. It has 12- to 18-foot walls topped with barbed wire. Internal wall sections -- internal walls sectioned off different portions of the compound to provide extra privacy. Access to the compound is restricted by two security gates, and the residents of the compound burn their trash, unlike their neighbors, who put the trash out for collection.

The main structure, a three-story building, has few windows facing the outside of the compound. A terrace on the third floor has a seven-foot wall privacy -- has a seven-foot privacy wall.

It’s also noteworthy that the property is valued at approximately $1 million but has no telephone or Internet service connected to it. The brothers had no explainable source of wealth.

Intelligence analysts concluded that this compound was custom built to hide someone of significance. We soon learned that more people were living at the compound than the two brothers and their families. A third family lived there -- one whose size and whose makeup matched the bin Laden family members that we believed most likely to be with Osama bin Laden. Our best assessment, based on a large body of reporting from multiple sources, was that bin Laden was living there with several family members, including his youngest wife.

Everything we saw -- the extremely elaborate operational security, the brothers’ background and their behavior, and the location and the design of the compound itself was perfectly consistent with what our experts expected bin Laden’s hideout to look like. Keep in mind that two of bin Laden’s gatekeepers, Khalid Sheikh Mohammed and Abu Faraj al-Libbi, were arrested in the settled areas of Pakistan.

Our analysts looked at this from every angle, considering carefully who other than bin Laden could be at the compound. We conducted red team exercises and other forms of alternative analysis to check our work. No other candidate fit the bill as well as bin Laden did.

So the final conclusion, from an intelligence standpoint, was twofold. We had high confidence that a high-value target was being harbored by the brothers on the compound, and we assessed that there was a strong probability that that person was Osama bin Laden.

Now let me turn it over to my colleague.

SENIOR ADMINISTRATION OFFICIAL: Thank you. Earlier this afternoon, a small U.S. team conducted a helicopter raid on the compound. Considerable planning helped prepare our operators for this very complex mission. Senior officials have been involved in the decision-making and planning for this operation for months, and briefed the President regularly. My colleague has already mentioned the unusual characteristics of this compound. Each of these, including the high walls, security features, suburban location, and proximity to Islamabad made this an especially dangerous operation.

The men who executed this mission accepted this risk, practiced to minimize those risks, and understood the importance of the target to the national security of the United States.

I know you understand that I can’t and won’t get into many details of this mission, but I’ll share what I can. This operation was a surgical raid by a small team designed to minimize collateral damage and to pose as little risk as possible to non-combatants on the compound or to Pakistani civilians in the neighborhood.

Our team was on the compound for under 40 minutes and did not encounter any local authorities while performing the raid. In addition to Osama bin Laden, three adult males were killed in the raid. We believe two were the couriers and the third was bin Laden’s adult son.

There were several women and children at the compound. One woman was killed when she was used as a shield by a male combatant. Two other women were injured.

During the raid, we lost one helicopter due to mechanical failure. The aircraft was destroyed by the crew and the assault force and crew members boarded the remaining aircraft to exit the compound. All non-combatants were moved safely away from the compound before the detonation.

That’s all I have at this time. I’ll turn it back to my colleague.

SENIOR ADMINISTRATION OFFICIAL: We shared our intelligence on this bin Laden compound with no other country, including Pakistan. That was for one reason and one reason alone: We believed it was essential to the security of the operation and our personnel. In fact, only a very small group of people inside our own government knew of this operation in advance.

Shortly after the raid, U.S. officials contacted senior Pakistani leaders to brief them on the intent and the results of the raid. We have also contacted a number of our close allies and partners throughout the world.

Sine 9/11, the United States has made it clear to Pakistan that we would pursue bin Laden wherever he might be. Pakistan has long understood that we are at war with al Qaeda. The United States had a legal and moral obligation to act on the information it had.

And let me emphasize that great care was taken to ensure operational success, minimize the possibility of non-combatant casualties, and to adhere to American and international law in carrying out the mission.

I should note that in the wake of this operation, there may be a heightened threat to the homeland and to U.S. citizens and facilities abroad. Al Qaeda operatives and sympathizers may try to respond violently to avenge bin Laden’s death, and other terrorist leaders may try to accelerate their efforts to strike the United States. But the United States is taking every possible precaution to protect Americans here at home and overseas. The State Department has sent guidance to embassies worldwide and a travel advisory has been issued for Pakistan.

And without a doubt, the United States will continue to face terrorist threats. The United States will continue to fight those threats. We have always understood that this fight would be a marathon and not a sprint.

There’s also no doubt that the death of Osama bin Laden marks the single greatest victory in the U.S.-led campaign to disrupt, dismantle, and defeat al Qaeda. It is a major and essential step in bringing about al Qaeda’s eventual destruction.

Bin Laden was al Qaeda’s only (inaudible) commander in its 22-year history, and was largely responsible for the organization’s mystique, its attraction among violent jihadists, and its focus on America as a terrorist target. As the only al Qaeda leader whose authority was universally respected, he also maintained his cohesion, and his likely successor, Ayman al-Zawahiri, is far less charismatic and not as well respected within the organization, according to comments from several captured al Qaeda leaders. He probably will have difficulty maintaining the loyalty of bin Laden’s largely Gulf Arab followers.

Although al Qaeda may not fragment immediately, the loss of bin Laden puts the group on a path of decline that will be difficult to reverse.

And finally, it’s important to note that it is most fitting that bin Laden’s death comes at a time of great movement towards freedom and democracy that is sweeping the Arab world. He stood in direct opposition to what the greatest men and women throughout the Middle East and North Africa are risking their lives for: individual rights and human dignity.

MR. VIETOR: With that we’re ready to take a couple questions.

Q One question. You said “a small U.S. team.” Were these military personnel, can you say, or non-military?

SENIOR ADMINISTRATION OFFICIAL: Can’t go into further details at this time; just a small U.S. team.

Q Good morning. Can you tell us specifically what contact there was with bin Laden at the compound? You referred to someone using a woman as a shield that was not bin Laden. But how was he killed? Where? What occurred at the compound?

SENIOR ADMINISTRATION OFFICIAL: As the President said this evening, bin Laden was killed in a firefight as our operators came onto the compound.

Q Thank you. Just to go back to what you were talking about with the attacks in response to this operation, are you hearing any specific threats against specific targets?

SENIOR ADMINISTRATION OFFICIAL: No. But any type of event like this, it is very prudent for us to take measures so that we can ensure that the security measures that we need to institute here and throughout the world are in place. This is just something that we normally would do. We don’t have any specific threats at this time related to this. But we are ensuring that every possible precaution is taken in advance.

Q Yes, hey, how are you doing? My question would be, what was the type of the helicopter that failed? And what was the nature of that mechanical failure?

SENIOR ADMINISTRATION OFFICIAL: Can’t go into details at this time.

SENIOR ADMINISTRATION OFFICIAL: We didn’t say it was mechanical.

Q Was bin Laden involved in firing himself or defending himself? And then any chronology of the raid itself?

SENIOR ADMINISTRATION OFFICIAL: He did resist the assault force. And he was killed in a firefight.

Q Thank you. Thank you for taking this call. Can you give me a comment on the very fact that Osama bin Laden was just in Islamabad -- and has long been (inaudible) Afghanistan (inaudible) also from India, that Osama bin Laden is hiding somewhere near Islamabad? What does it signify, that? Does it signify any cooperation or any kind of link that he had with establishments in Pakistan?

SENIOR ADMINISTRATION OFFICIAL: As the President said, Pakistani cooperation had assisted in this lead, as we pursued it. So we’re continuing to work this issue right now. We are very concerned about -- that he was inside of Pakistan, but this is something that we’re going to continue to work with the Pakistani government on.

Q But the very fact you didn’t inform the Pakistani authorities -- did you have any suspicion that if you informed them, the information might lead somewhere?

SENIOR ADMINISTRATION OFFICIAL: An operation like this that is conducted has the utmost operational security attached to it. I said that we had shared this information with no other country, and that a very, very small group of individuals within the United States government was aware of this. That is for operational security purposes.

SENIOR ADMINISTRATION OFFICIAL: I would also just add to that that President Obama, over a period of several years now, has repeatedly made it clear that if we had actionable intelligence about Osama bin Laden’s whereabouts, we would act. So President Obama has been very clear in delivering that message publicly over a period of years. And that’s what led President Obama to order this operation. When he determined that the intelligence was actionable and the intelligence case was sufficient, he gave us high confidence that bin Laden indeed was at the compound.

Q Thank you. What is going to happen next? And what is the U.S. going to do with bin Laden’s body?

SENIOR ADMINISTRATION OFFICIAL: We are ensuring that it is handled in accordance with Islamic practice and tradition. This is something that we take very seriously. And so therefore this is being handled in an appropriate manner.

MR. VIETOR: Great, thanks. Just to remind everyone, this call is on background, as senior administration officials. We have time for one more question, and we’re going to go to bed.

Q Do you have a sense of the vintage of the compound and how long bin Laden had been there?

SENIOR ADMINISTRATION OFFICIAL: The compound has been in existence for roughly five years, but we don’t know how long bin Laden lived there. We assess that the compound was built for the purpose of harboring him. But again, don’t know how long he’s been there.

MR. VIETOR: Great, thank you all. We’ll talk more tomorrow.

Time to Recall Rick Scott

Florida's Governor Rick Scott has made the decision in April 2011 to not sue BP for its role in the oil spill of 2010. This brings rise to the question of who is Rick Scott working for; this move proves his intentions are not aimed at the good of the state.

"By Ralph De
La Cruz Florida Center for Investigative Reporting

Rick Scott came into the governor’s office without having ever governed. Not even a term on a school board. He never even had to get folks to reach consensus in a precinct. Scott’s main qualification to be governor was that he was CEO of an HMO found guilty of the worst case of Medicare fraud in U.S. history. He’s such a newbie that he doesn’t grasp the most fundamental concept about governing: Politics is the art of compromise. FCIR relies on grants from foundations and donations from readers. Donate today to support investigative journalism in Florida. Academics Donald J. Boudreaux and Dwight H. Lee, writing for no less a conservative voice than the Cato Institute, can explain: “Regardless of the terms employed, few doubt that politics is indeed the art of compromise. Politicians unwilling to compromise are typically labeled ideologues — a label not regarded as a badge of honor among members of the political class. Moreover, politicians who refuse to compromise seldom win and hold on to office …” Being CEO, on the other hand, is the art of applying force and pressure. Running a company is nothing like running a state. And that’s becoming clearer with each passing day of Scott’s term. The tea party’s governor came into office in January like a man possessed — and unconcerned about anyone but his business buddies and the tea party set. He showed little interest in building compromise or coalitions, immediately going after teachers and county and state workers as if they were his employees. Pawns to be moved and sacrificed as only he sees fit. He has shown a disinterest in working with minorities. When Scott met with black lawmakers who were concerned he does not have a single minority in his cabinet, he tried to ingratiate himself by saying he could relate to them: He had grown up in public housing with a parent who had a sixth-grade education. How charming. Scott, who was viewed with suspicion by Hispanics during the campaign because of his promise to bring harsh Arizona-style immigration enforcement to the state, briefly softened his stance — at least until after his brief appearance at the Hispanic Leadership Network. Then he reverted back to his old rhetoric. His budget, presented to a tea party rally as if the rest of the state didn’t matter, pushed corporate tax cuts onto the backs of teachers, county and state workers, and correctional officers. Maybe if those correctional officers had contributed $100,000 at his inauguration, which was a dolled-up fundraiser for him and the Florida Republican Party, things might have been different. But instead, it was the Geo Group — which runs private prisons and employs Scott’s close chum, Bill Rubin, as its lobbyist – handing out the checks. And surprise, one of the first targets of Scott’s decimation of the state infrastructure was … the state prison system. Scott campaigned against the hiring of state lobbyists, then hired state lobbyists. The difference, he explained, was that these were his lobbyists. He threw state Sen. Paula Dockery, one of his earliest political supporters, under the political bus (or train) by rejecting $2.4 billion in federal money for a high-speed rail project that she had been working on for years. That decision reportedly occurred after he met with tea partiers in his office. Hey, appeasing those loyal tea partiers by making an anti-Obama statement comes before political loyalty — or creating upwards of 20,000 Florida jobs. It is as if we suddenly have en emperor in Tallahassee, issuing policy by decree. That might be the way to run a corporation. But it’s no way to run a state. The way Scott has acted, running roughshod over constituents and supporters alike, you’d think the man had won his election by a massive margin — what politicians call a “mandate.” But actually, Scott beat a Democrat in a ruby-red Republican state by one percentage point. Less than 62,000 votes gave him the keys to the mansion. And that sliver of a margin came after spending $73 million of his personal fortune, avoiding the press and opponents until the very end of the campaign, and relying on his mother and wife to be his political face during the campaign. Looking back, it was an impressive blueprint for how to win an electoral victory. Not so much for how to be successful at governing. Now, he occupies office with few allies other than tea partiers and the business elite. Even Republicans and early political supporters — burned by Scott’s sudden, bizarre and illogical decisions such as killing a database tracking addictive pill prescriptions — seem perplexed. Last week, the Senate, overwhelmingly controlled by his party, voted by a veto-proof majority to continue going after the money for the Central Florida rail project. Republican Sen. J.D. Alexander questioned whether Scott had the legal authority to do what he had done, and another Republican senator, David Simmons, vowed to lobby fellow legislators to overturn Scott’s decision. It’s hard to find anyone other than tea party zealots who have a kind word to say about Scott. The other day, a short story in a Treasure Coast/Palm Beach County publication simply announcing a Scott appearance at a Republican fundraiser in Martin County drew a rash of angry comments, such as, “I wonder if Gov. Scott will share the fact that his budget proposal includes increasing his executive office’s budget by over $300 million?” And, “If you’re a senior citizen attending this event, hide your medicare card. Just saying …” Citizens have now formed a Facebook group to advocate his recall. This after less than two months in office. But they should probably speak with Rep. Rick Kriseman first. Last week, Kriseman introduced a bill that would allow the recall of state officials. I know what you’re thinking: Scary that we don’t already have that right. Yep. It’s past time. Thank you, Rep. Kriseman. HB 787 should be automatic, considering the legislature is controlled by Republicans, who often tout accountability as a cornerstone of their party. We’ll soon see whether for them (and their tea party supporters), accountability only applies to teachers and welfare recipients. Or whether it’s for all Floridians, regardless of position, pocketbook or political persuasion."

Thousands flee fierce Colorado wildfire

A fierce wildfire west of Boulder, Colo., which destroyed dozens of homes and caused 3,000 people to flee Monday, continued to rage uncontained Tuesday afternoon.
Boulder County Sheriff Joe Pelle says the fire has burned about 7,100 acres, or 11 square miles. Authorities previously estimated the fire at 3,500 acres. Additional evacuations are expected.
Colorado Gov. Bill Ritter says he has declared a state of emergency and authorized $5 million for the fire.
According to Mike Banuelos, Boulder County public information officer, as of Tuesday afternoon, there is no information about containment yet.
About 175 firefighters from 30 local agencies are battling the blaze, he said.
MILD FIRES:USA catches a break this year with mild wildfire season
Four homes belonging to firefighters were destroyed. Those firefighters were allowed to leave to attend to their families and personal affairs, said Laura McConnell, a spokeswoman for the fire management team.
The weather is far better for firefighters Tuesday than it was Monday. "We have nothing like the extreme conditions we had yesterday," said Chad Gimmestad, a forecaster with the National Weather Service in Boulder.
He said Monday's wild winds and parched, hot conditions helped spread the fire. "At the top of the ridges, winds blew at 40-50 mph for several hours," Gimmestad said. The wind was coupled with humidity levels of 5% to 10%, a day after a near-record high of 94 degrees was recorded.
"The fire moved too quickly and was much more active than anticipated," said Brett Haberstick of the Sunshine Fire Protection District.
It's still unclear what sparked the Fourmile Canyon Fire, as it has been named, although authorities are investigating reports that the fire started Monday when a car crashed into a propane tank.
"We do have an investigative team set up that has started to investigate the cause of the fire and go up into the burned area to document what structures have been involved, what structures have been destroyed," Cmdr. Rick Brough of the Boulder County Emergency Management said during a Tuesday morning news conference.
Although no injuries have been reported in the wildfire, a number of people woke up Tuesday fearing the loss of their homes.
Nancy Engellenner and her husband, Philip Helper, assume their house was lost because so much was destroyed in the surrounding area.
"The way the wind was, it was just spitting flames everywhere," Engellenner said.
Resident David Myers also feared his house burned after he fled. At one point, he said heavy smoke obscured flames from the fire but he could still hear it. He described the sound as a cross between a freight train and a long roll of thunder.
"You can hear the crackling, you can hear just this consumption of fuel, just crackling and burning. And the hardest thing is you couldn't see it because at the point the smoke was that thick. And at that point, it was time to go," he said.
The weather for the rest of the week in the area should continue to be dry and windy, predicts Gimmestad, with little chance of rain.

Best chance for life beyond Earth # 2: Enceladus




After Mars, Saturn and its several moons is the nearest best chance for finding life beyond Earth. In addition to the possibility of life the Saturn system possesses the best chance for finding natural resources such as methane and water.

The next large moon is Enceladus, measuring 504 km across, and orbiting at 238,000 km from the center of Saturn. NASA's Cassini spacecraft recently discovered geysers of water ice pouring out of Enceladus' southern pole. Astronomers think that there could be vast reserves of liquid water underneath the moon's icy surface.

Enceladus has the highest albedo (>0.9) of any body in the solar system. Its surface is dominated by fresh, clean ice.

At least five different types of terrain have been identified on Enceladus. In addition to craters there are smooth plains and extensive linear cracks and ridges. At least some of the surface is relatively young, probably less than 100 million years.

This means that Enceladus must have been active until very recently (and perhaps is still active today). Perhaps some sort of "water volcanism" is at work.

Enceladus is much too small to be heated solely by the decay of radioactive material in its interior at present. But briefly after its formation 4.5 billion years ago short-lived radioisotopes may have provided enough heat to melt and differentiate the interior. That combined with modest present day heating from long-lived isotopes and tidal heating may account for the present day activity on Enceladus.

Cassini closeup view (looks like Europa?) Enceladus is locked in a 1:2 resonance with Dione (similar to the situation between Io and Europa). This may provide a heating mechanism but it is probably insufficient to melt water ice. Enceladus may therefore be composed of some low-melting point material rather than pure water.

Enceladus is very likely the source of the material in Saturn's tenuous E ring. And since the material cannot persist in the ring for more than a few thousand years, it must be due to very recent activity on Enceladus. A less likely possibility is that the rings are maintained by high-velocity collisions between dust particles and the various moons.

Best chance for life beyond Earth # 3: Europa




Europa (pronounced /jʊˈroʊpə/ ( listen); or as Greek Ευρώπη) is the sixth moon of the planet Jupiter, and the smallest of its four Galilean satellites. Europa was discovered in 1610 by Galileo Galilei (and possibly independently by Simon Marius), and named after a mythical Phoenician noblewoman, Europa, who was courted by Zeus and became the queen of Crete.

Roughly the size of Earth's Moon, Europa is primarily made of silicate rock and likely has an iron core. It has a tenuous atmosphere composed primarily of oxygen. Its surface is composed of ice and is one of the smoothest in the Solar System. This surface is striated by cracks and streaks, while craters are relatively infrequent. The apparent youth and smoothness of the surface have led to the hypothesis that a water ocean exists beneath it, which could conceivably serve as an abode for extraterrestrial life.[12] This hypothesis proposes that heat energy from tidal flexing causes the ocean to remain liquid and drives geological activity similar to plate tectonics.[13]

Although only fly-by missions have visited the moon, the intriguing characteristics of Europa have led to several ambitious exploration proposals. The Galileo mission provided the bulk of current data on Europa. A new mission to Jupiter's icy moons, the Europa Jupiter System Mission (EJSM), is proposed for a launch in 2020.[14] Conjecture on extraterrestrial life has ensured a high profile for the moon and has led to steady lobbying for future missions.

Is The Last Airbender Racist



"Some viewers heads are spinning over the look of 'The Last Airbender,' which opens July 1. Not over the fantasy-action 3-D special effects, but over the faces of the main characters, which are largely white in the movie but Asian and Inuit in the popular Nickelodeon cartoon that inspired the film.

Complicating the accusations of racial insensitivity over the casting is the fact that those casting decisions were made by director M. Night Shyamalan, who is of Asian descent himself. In fact, Shyamalan bristles at the accusations and insists that, not only is his cast as multicultural as possible, but also that it's his critics who are the real racists.

The characters in the TV series 'Avatar: The Last Airbender,' created by Bryan Konietzko and Michael Dante DiMartino, are clearly drawn from Asian and Inuit cultures, from their names to their costumes to their martial arts styles. The hero, Aang, is inspired by Tibetan Buddhist monks. His friends, Katara and Sokka, live in a realm of anoraks and igloos. Antagonist Zuko and his tribe appear as classical Chinese warriors.

In the movie, all four characters were initially cast as Caucasian actors: Noah Ringer (Aang), Nicola Peltz (Katara), Jackson Rathbone (Sokka), and Jesse McCartney (Zuko). Before shooting began, however, McCartney was replaced by Dev Patel, of 'Slumdog Millionaire' fame. That change did not appease the project's critics, who noted that the heroes were still all white Westerners, while the only Asian in the principal cast was the villain.

The clearinghouse for the protests has been the website Racebending, which is calling for a boycott of the film. "American actors of color rarely get to play the hero, if ever," said Marissa Lee, one of Racebending's co-founders, in a statement. "We're really disappointed. Paramount felt that white actors were better suited to play heroes of color than hardworking, underrepresented actors who are actually of Asian or Inuit descent."

Shyamalan has insisted he had no intention of whitewashing the characters. In a recent interview with Indie Movies Online, he went into great detail about the casting choices, which he said were entirely his and not Paramount's. He argued that the complaints didn't look beyond the principal players to note the entire cast, which consists of actors from multiple cultures and racial backgrounds playing the 'Airbender' world's four tribes. Of the protest, he said, "The irony of this statement enrages me to the point of ... not even the accusation, but the misplacement of it. You're coming at me, the one Asian filmmaker who has the right to cast anybody I want, and I'm casting this entire movie in this color blind way where everyone is represented. I even had one section of the Earth kingdom as African American, which obviously isn't in the show, but I wanted to represent them, too!"

Why, then, did he cast white actors in the leads? "Noah Ringer walked in the door -- and there was no other human being on the planet that could play Aang except for this kid," the director said. "To me, he felt mixed race with an Asian quality to him. I made all the Air nomads mixed race – some of them are Hispanic, some of them are Korean." Patel's people had to look like him, too, which is the reason the members of the hot-tempered Fire tribe are all played by darker-hued actors.

With three of the tribes played by non-Caucasian actors, Shyamalan said he felt the fourth group, Katara and Sokka's Water tribe, could be played by white actors. "If you don't have an edict of "don't put white people in the movie" then the Water tribe can be European/Caucasian," he said. So, by his logic, casting white actors as Katara and Sokka was actually an act of inclusion, not exclusion. (It's worth noting here, as Shyamalan has, that the cartoon's adherence to the visual conventions of Japanese anime, including round eyes and light skin, have added to the racial confusion. If the characters are drawn with racially indeterminate features, why shouldn't his casting follow suit?) "
