NASA’s Cassini–Huygens spacecraft has discovered evidence for a large-scale saltwater reservoir beneath the icy crust of Saturn’s moon Enceladus. The data came from the spacecraft’s direct analysis of salt-rich ice grains close to the jets ejected from the moon. The study has been published in this week’s edition of the journal Nature.

Data from Cassini’s cosmic dust analyzer show the grains expelled from fissures, known as tiger stripes, are relatively small and usually low in salt far away from the moon. Closer to the moon’s surface, Cassini found that relatively large grains rich with sodium and potassium dominate the plumes. The salt-rich particles have an “ocean-like” composition and indicate that most, if not all, of the expelled ice and water vapor comes from the evaporation of liquid salt-water. When water freezes, the salt is squeezed out, leaving pure water ice behind.

Cassini’s ultraviolet imaging spectrograph also recently obtained complementary results that support the presence of a subsurface ocean. A team of Cassini researchers led by Candice Hansen of the Planetary Science Institute in Tucson, Arizona, measured gas shooting out of distinct jets originating in the moon’s south polar region at five to eight times the speed of sound, several times faster than previously measured. These observations of distinct jets, from a 2010 flyby, are consistent with results showing a difference in composition of ice grains close to the moon’s surface and those that made it out to the E ring, the outermost ring that gets its material primarily from Enceladean jets. If the plumes emanated from ice, they should have very little salt in them.

“There currently is no plausible way to produce a steady outflow of salt-rich grains from solid ice across all the tiger stripes other than salt water under Enceladus’s icy surface,” said Frank Postberg, a Cassini team scientist at the University of Heidelberg in Germany.

The data suggests a layer of water between the moon’s rocky core and its icy mantle, possibly as deep as about 50 miles (80 kilometers) beneath the surface. As this water washes against the rocks, it dissolves salt compounds and rises through fractures in the overlying ice to form reserves nearer the surface. If the outermost layer cracks open, the decrease in pressure from these reserves to space causes a plume to shoot out. Roughly 400 pounds (200 kilograms) of water vapor is lost every second in the plumes, with smaller amounts being lost as ice grains. The team calculates the water reserves must have large evaporating surfaces, or they would freeze easily and stop the plumes.

“We imagine that between the ice and the ice core there is an ocean of depth and this is somehow connected to the surface reservoir,” added Postberg.

The Cassini mission discovered Enceladus’ water-vapor and ice jets in 2005. In 2009, scientists working with the cosmic dust analyzer examined some sodium salts found in ice grains of Saturn’s E ring but the link to subsurface salt water was not definitive. The new paper analyzes three Enceladus flybys in 2008 and 2009 with the same instrument, focusing on the composition of freshly ejected plume grains. In 2008, Cassini discovered a high “density of volatile gases, water vapor, carbon dioxide and carbon monoxide, as well as organic materials, some 20 times denser than expected” in geysers erupting from the moon. The icy particles hit the detector target at speeds between 15,000 and 39,000 MPH (23,000 and 63,000 KPH), vaporizing instantly. Electrical fields inside the cosmic dust analyzer separated the various constituents of the impact cloud.

“Enceladus has got warmth, water and organic chemicals, some of the essential building blocks needed for life,” said Dennis Matson in 2008, Cassini project scientist at NASA’s Jet Propulsion Laboratory in Pasadena, California.

“This finding is a crucial new piece of evidence showing that environmental conditions favorable to the emergence of life can be sustained on icy bodies orbiting gas giant planets,” said Nicolas Altobelli, the European Space Agency’s project scientist for Cassini.

“If there is water in such an unexpected place, it leaves possibility for the rest of the universe,” said Postberg.

Wikinews accredited reporter Killing Vector traveled to the G-20 2009 summit protests in London with a group of protesters. This is his personal account.

London — “Protest”, says Ross Saunders, “is basically theatre”.

It’s seven a.m. and I’m on a mini-bus heading east on the M4 motorway from Cardiff toward London. I’m riding with seventeen members of the Cardiff Socialist Party, of which Saunders is branch secretary for the Cardiff West branch; they’re going to participate in a march that’s part of the protests against the G-20 meeting.

Before we boarded the minibus Saunders made a speech outlining the reasons for the march. He said they were “fighting for jobs for young people, fighting for free education, fighting for our share of the wealth, which we create.” His anger is directed at the government’s response to the economic downturn: “Now that the recession is underway, they’ve been trying to shoulder more of the burden onto the people, and onto the young people…they’re expecting us to pay for it.” He compared the protest to the Jarrow March and to the miners’ strikes which were hugely influential in the history of the British labour movement. The people assembled, though, aren’t miners or industrial workers — they’re university students or recent graduates, and the march they’re going to participate in is the Youth Fight For Jobs.

The Socialist Party was formerly part of the Labour Party, which has ruled the United Kingdom since 1997 and remains a member of the Socialist International. On the bus, Saunders and some of his cohorts — they occasionally, especially the older members, address each other as “comrade” — explains their view on how the split with Labour came about. As the Third Way became the dominant voice in the Labour Party, culminating with the replacement of Neil Kinnock with Tony Blair as party leader, the Socialist cadre became increasingly disaffected. “There used to be democratic structures, political meetings” within the party, they say. The branch meetings still exist but “now, they passed a resolution calling for renationalisation of the railways, and they [the party leadership] just ignored it.” They claim that the disaffection with New Labour has caused the party to lose “half its membership” and that people are seeking alternatives. Since the economic crisis began, Cardiff West’s membership has doubled, to 25 members, and the RMT has organized itself as a political movement running candidates in the 2009 EU Parliament election. The right-wing British National Party or BNP is making gains as well, though.

Talk on the bus is mostly political and the news of yesterday’s violence at the G-20 demonstrations, where a bank was stormed by protesters and 87 were arrested, is thick in the air. One member comments on the invasion of a RBS building in which phone lines were cut and furniture was destroyed: “It’s not very constructive but it does make you smile.” Another, reading about developments at the conference which have set France and Germany opposing the UK and the United States, says sardonically, “we’re going to stop all the squabbles — they’re going to unite against us. That’s what happens.” She recounts how, in her native Sweden during the Second World War, a national unity government was formed among all major parties, and Swedish communists were interned in camps, while Nazi-leaning parties were left unmolested.

In London around 11am the march assembles on Camberwell Green. About 250 people are here, from many parts of Britain; I meet marchers from Newcastle, Manchester, Leicester, and especially organized-labor stronghold Sheffield. The sky is grey but the atmosphere is convivial; five members of London’s Metropolitan Police are present, and they’re all smiling. Most marchers are young, some as young as high school age, but a few are older; some teachers, including members of the Lewisham and Sheffield chapters of the National Union of Teachers, are carrying banners in support of their students.

Stewards hand out sheets of paper with the words to call-and-response chants on them. Some are youth-oriented and education-oriented, like the jaunty “Gordon Brown‘s a Tory/He wears a Tory hat/And when he saw our uni fees/He said ‘I’ll double that!'” (sung to the tune of the Lonnie Donegan song “My Old Man’s a Dustman“); but many are standbys of organized labour, including the infamous “workers of the world, unite!“. It also outlines the goals of the protest, as “demands”: “The right to a decent job for all, with a living wage of at least £8 and hour. No to cheap labour apprenticeships! for all apprenticeships to pay at least the minimum wage, with a job guaranteed at the end. No to university fees. support the campaign to defeat fees.” Another steward with a megaphone and a bright red t-shirt talks the assembled protesters through the basics of call-and-response chanting.

Finally the march gets underway, traveling through the London boroughs of Camberwell and Southwark. Along the route of the march more police follow along, escorting and guiding the march and watching it carefully, while a police van with flashing lights clears the route in front of it. On the surface the atmosphere is enthusiastic, but everyone freezes for a second as a siren is heard behind them; it turns out to be a passing ambulance.

Crossing Southwark Bridge, the march enters the City of London, the comparably small but dense area containing London’s financial and economic heart. Although one recipient of the protesters’ anger is the Bank of England, the march does not stop in the City, only passing through the streets by the London Exchange. Tourists on buses and businessmen in pinstripe suits record snippets of the march on their mobile phones as it passes them; as it goes past a branch of HSBC the employees gather at the glass store front and watch nervously. The time in the City is brief; rather than continue into the very centre of London the march turns east and, passing the Tower of London, proceeds into the poor, largely immigrant neighbourhoods of the Tower Hamlets.

The sun has come out, and the spirits of the protesters have remained high. But few people, only occasional faces at windows in the blocks of apartments, are here to see the march and it is in Wapping High Street that I hear my first complaint from the marchers. Peter, a steward, complains that the police have taken the march off its original route and onto back streets where “there’s nobody to protest to”. I ask how he feels about the possibility of violence, noting the incidents the day before, and he replies that it was “justified aggression”. “We don’t condone it but people have only got certain limitations.”

A policeman I ask is very polite but noncommittal about the change in route. “The students are getting the message out”, he says, so there’s no problem. “Everyone’s very well behaved” in his assessment and the atmosphere is “very positive”. Another protestor, a sign-carrying university student from Sheffield, half-heartedly returns the compliment: today, she says, “the police have been surprisingly unridiculous.”

The march pauses just before it enters Cable Street. Here, in 1936, was the site of the Battle of Cable Street, and the march leader, addressing the protesters through her megaphone, marks the moment. She draws a parallel between the British Union of Fascists of the 1930s and the much smaller BNP today, and as the protesters follow the East London street their chant becomes “The BNP tell racist lies/We fight back and organise!”

In Victoria Park — “The People’s Park” as it was sometimes known — the march stops for lunch. The trade unions of East London have organized and paid for a lunch of hamburgers, hot dogs, french fries and tea, and, picnic-style, the marchers enjoy their meals as organized labor veterans give brief speeches about industrial actions from a small raised platform.

During the rally I have the opportunity to speak with Neil Cafferky, a Galway-born Londoner and the London organizer of the Youth Fight For Jobs march. I ask him first about why, despite being surrounded by red banners and quotes from Karl Marx, I haven’t once heard the word “communism” used all day. He explains that, while he considers himself a Marxist and a Trotskyist, the word communism has negative connotations that would “act as a barrier” to getting people involved: the Socialist Party wants to avoid the discussion of its position on the USSR and disassociate itself from Stalinism. What the Socialists favor, he says, is “democratic planned production” with “the working class, the youths brought into the heart of decision making.”

On the subject of the police’s re-routing of the march, he says the new route is actually the synthesis of two proposals. Originally the march was to have gone from Camberwell Green to the Houses of Parliament, then across the sites of the 2012 Olympics and finally to the ExCel Centre. The police, meanwhile, wanted there to be no march at all.

The Metropolitan Police had argued that, with only 650 trained traffic officers on the force and most of those providing security at the ExCel Centre itself, there simply wasn’t the manpower available to close main streets, so a route along back streets was necessary if the march was to go ahead at all. Cafferky is sceptical of the police explanation. “It’s all very well having concern for health and safety,” he responds. “Our concern is using planning to block protest.”

He accuses the police and the government of having used legal, bureaucratic and even violent means to block protests. Talking about marches having to defend themselves, he says “if the police set out with the intention of assaulting marches then violence is unavoidable.” He says the police have been known to insert “provocateurs” into marches, which have to be isolated. He also asserts the right of marches to defend themselves when attacked, although this “must be done in a disciplined manner”.

He says he wasn’t present at yesterday’s demonstrations and so can’t comment on the accusations of violence against police. But, he says, there is often provocative behavior on both sides. Rather than reject violence outright, Cafferky argues that there needs to be “clear political understanding of the role of violence” and calls it “counter-productive”.

Demonstration overall, though, he says, is always a useful tool, although “a demonstration is always a means to an end” rather than an end in itself. He mentions other ongoing industrial actions such as the occupation of the Visteon plant in Enfield; 200 fired workers at the factory have been occupying the plant since April 1, and states the solidarity between the youth marchers and the industrial workers.

I also speak briefly with members of the International Bolshevik Tendency, a small group of left-wing activists who have brought some signs to the rally. The Bolsheviks say that, like the Socialists, they’re Trotskyists, but have differences with them on the idea of organization; the International Bolshevik Tendency believes that control of the party representing the working class should be less democratic and instead be in the hands of a team of experts in history and politics. Relations between the two groups are “chilly”, says one.

At 2:30 the march resumes. Rather than proceeding to the ExCel Centre itself, though, it makes its way to a station of London’s Docklands Light Railway; on the way, several of East London’s school-aged youths join the march, and on reaching Canning Town the group is some 300 strong. Proceeding on foot through the borough, the Youth Fight For Jobs reaches the protest site outside the G-20 meeting.

It’s impossible to legally get too close to the conference itself. Police are guarding every approach, and have formed a double cordon between the protest area and the route that motorcades take into and out of the conference venue. Most are un-armed, in the tradition of London police; only a few even carry truncheons. Closer to the building, though, a few machine gun-armed riot police are present, standing out sharply in their black uniforms against the high-visibility yellow vests of the Metropolitan Police. The G-20 conference itself, which started a few hours before the march began, is already winding down, and about a thousand protesters are present.

I see three large groups: the Youth Fight For Jobs avoids going into the center of the protest area, instead staying in their own group at the admonition of the stewards and listening to a series of guest speakers who tell them about current industrial actions and the organization of the Youth Fight’s upcoming rally at UCL. A second group carries the Ogaden National Liberation Front‘s flag and is campaigning for recognition of an autonomous homeland in eastern Ethiopia. Others protesting the Ethiopian government make up the third group; waving old Ethiopian flags, including the Lion of Judah standard of emperor Haile Selassie, they demand that foreign aid to Ethiopia be tied to democratization in that country: “No recovery without democracy”.

A set of abandoned signs tied to bollards indicate that the CND has been here, but has already gone home; they were demanding the abandonment of nuclear weapons. But apart from a handful of individuals with handmade, cardboard signs I see no groups addressing the G-20 meeting itself, other than the Youth Fight For Jobs’ slogans concerning the bailout. But when a motorcade passes, catcalls and jeers are heard.

It’s now 5pm and, after four hours of driving, five hours marching and one hour at the G-20, Cardiff’s Socialists are returning home. I board the bus with them and, navigating slowly through the snarled London traffic, we listen to BBC Radio 4. The news is reporting on the closure of the G-20 conference; while they take time out to mention that Canadian Prime Minister Stephen Harper delayed the traditional group photograph of the G-20’s world leaders because “he was on the loo“, no mention is made of today’s protests. Those listening in the bus are disappointed by the lack of coverage.

Most people on the return trip are tired. Many sleep. Others read the latest issue of The Socialist, the Socialist Party’s newspaper. Mia quietly sings “The Internationale” in Swedish.

Due to the traffic, the journey back to Cardiff will be even longer than the journey to London. Over the objections of a few of its members, the South Welsh participants in the Youth Fight For Jobs stop at a McDonald’s before returning to the M4 and home.

A suicide bomber killed 43 people in Iraq Sunday, injuring an estimated 40 more.

The attack occurred southwest of Baghdad and targeted members of a government-backed militia, Sons of Iraq, also known as the Sahwa, who were waiting to collect their pay. Early reports say the attacks killed at least three soldiers and injured an additional thirteen, while three accountants died and four more were wounded. It’s not yet clear who the remaining casualties are.

A survivor of the bombing said that “[t]here were more than 85 people lined up in three lines at the main gate of the military base to receive salaries when a person approached us. When one of the soldiers tried to stop him, he blew himself up.”

An Iraqi military official said that “[t]he suicide bomber blew himself up in the biggest group of Sahwa members. We generally let them enter the base in groups of 10 for them to get their salaries.”

A second suicide bombing took place in Western Iraq, when an attacker fired upon Sahwa militants in Al-Qa’im before blowing himself up, killing three people, with six more injured.

Credit for the attacks has not yet been claimed, but al-Qaeda is considered the probable culprit.

The Sahwa movement is a Sunni militia group that split from al-Qaeda in 2006, and with US support have been one of the groups fighting al-Qaeda. In recent months, members of the militia have said that they have come under attack from other militant groups, and support from the Iraqi government has been reduced.

Witnesses heard gunshots in a Wal-Mart parking lot in Cedar Park, Texas, near Highway 183, on Sunday morning. Police arrested eighteen year-old Soloman Onwukaife at the scene. Four, including the gunman who had facial wounds unrelated to the shooting, are being treated for injuries after the incident. A fifth victim has been released.

Cedar Park Police Captain Mike Harmon said authorities arrived at the parking lot around 4:30 AM local time. There they arrested Onwukaife, who has been charged with aggravated assault with a deadly weapon. The Cedar Park Wal-Mart was closed down briefly on Sunday morning; however, no staff or customers were injured.

Police have released the names of the victims, eighteen-year-old Cody McGrath, nineteen-year-old Shayne Davis, nineteen-year-old Zacharia Gietl and 22-year-old Leland McGlocklin. As-of Monday, Gietl has been released from hospital whilst the others remain in critical, but stable, condition. Police informed media the incident occurred follwing a dispute which began at a nearby party where alcohol was being served. After moving the fight to the parking lot, Onwukaife is alleged to have shot the four victims.

Onwukaife was expected to be released on Monday, after which he would immediately be jailed. Police advised media the investigation is on-going and more charges may still be filed. Specifically, Police are trying to determine if any other participants in the fight were armed.

Buffalo, New York —Wikinews was the first to tell you that the Elmwood Village Hotel development in Buffalo, New York was to undergo “significant changes”.

The Elmwood Village Hotel is a proposed project that would be placed at Elmwood and Forest Aves. in Buffalo. In order for the development to take place, at least five buildings that house both businesses and residents, must be demolished.

To confirm and to get more information about the changes, Wikinews interviewed Eva Hassett, Vice President of Savarino Construction Services Corporation, the development company in charge of building the hotel.

Wikinews: The hotel proposal is being redesigned. Could you comment on that? What changes are being made? Are they significant?

Eva Hassett: The hotel has been resized as a 72-room, four story building. This is 10% smaller in number of rooms and a full story lower. We are also redesigning the facades in a way that will minimize the mass – more of a vertical feeling than horizontal. Different materials, windows, details. The smaller size of the hotel also makes the number of on-site parking spaces more appropriate and hopefully represents less of a challenge to an already difficult parking situation.

WN: Will you still be going before the city’s planning board as scheduled on February 28? Same for the Common Council?

Hassett: We will be on the Planning Board agenda this Tuesday morning but I do not expect that the Board will vote on the item that morning. I think we will be mainly explaining the new design and hearing input/questions.

WN: Will there be anymore public meetings?

Hassett: We would be happy to do one more big public meeting. We will be talking to Forever Elmwood about that on Monday (February 27, 2006). We would like to see if there is support for the new design and we also want to honor the public’s request for another meeting. I am hopeful that meeting can take place the week of March 6th.

WN: Is Savarino considering Mr. Rocco Termini’s design/proposal? If no, do you (Savarino) support/oppose?

Hassett: We are hopeful that we can build the hotel as redesigned. We think it would be a great addition to the Elmwood Ave. area, a good way for out-of-towners to see what Buffalo offers and a big help to the businesses there.

WN: Are you considering more time for the community to make a judgment?

Hassett: As I mentioned above, we expect to have one more meeting to get public reaction to the new design, and I think the Planning Board may want an additional meeting to make their determination. We do however, have constraints that will limit the amount of extra time. We still think it is a great project for the City and Elmwood; and we still want it to be something that the community wants as well.

So far, the City of Buffalo’s City Planning Board is still scheduled to meet at 8:00 a.m. (Eastern) on February 28, 2006 followed by the Common Council meeting at 2:00 p.m. on the same day.

Images of the design are not yet available. “We are working on the renderings this weekend, but I will likely have some early in the week,” stated Hassett.

American helicopters and warplanes bombed 2 villages near Ramadi, Iraq on Sunday. The U.S. military said nearly 70 suspected insurgents were killed, while local witnesses said that at least 39 civilians, including 18 children, were also lost to the attack.

A Ramadi resident, Ahmed Fouad, said that just after 7 p.m. Sunday, U.S. warplanes killed 18 children, including Fouad’s son and 8-year-old daughter. “She was killed with her brother. Her mother had a stroke out of shock.” Fouad said.

Family members of victims gathered at a Ramadi General Hospital where refrigeration space for the dead bodies had been exhausted. In the garden the bodies of a woman and three children lay as relatives sifted through remains.

“[They] were not terrorists…they were only a bunch of civilians whose curiosity prompted them to gather around a destroyed Humvee,” said Dr. Dhiya Fahdawi in reference to the dead and wounded.

The U.S. military neither confirmed nor denied that civilians were killed and issued a statement saying; “All the attacks were timed and executed in a manner to reduce the possibility of collateral damage.”
