The Hellenic Navy (HN) (Greek: Πολεμικό Ναυτικό, Polemikó Naftikó, abbreviated ΠΝ) is the naval force of Greece, part of the Greek Armed Forces. The modern Greek navy has its roots in the naval forces of various Aegean Islands, which fought in the Greek War of Independence. During the periods of monarchy (1833–1924 and 1936–1973) it was known as the Royal Navy (Βασιλικόν Ναυτικόν, Vasilikón Naftikón, abbreviated ΒΝ).The total displacement of all the navy's vessels is approximately 150,000 tons.The motto of the Hellenic Navy is "Μέγα το της Θαλάσσης Κράτος" from Thucydides' account of Pericles' oration on the eve of the Peloponnesian War. This has been roughly translated as "Great is the country that controls the sea". The Hellenic Navy's emblem consists of an anchor in front of a crossed Christian cross and trident, with the cross symbolizing Greek Orthodoxy, and the trident symbolizing Poseidon, the god of the sea in Greek mythology. Pericles' words are written across the top of the emblem. "The navy, as it represents a necessary weapon for Greece, should only be created for war and aim to victory."...............The Hellenic Merchant Marine refers to the Merchant Marine of Greece, engaged in commerce and transportation of goods and services universally. It consists of the merchant vessels owned by Greek civilians, flying either the Greek flag or a flag of convenience. Greece is a maritime nation by tradition, as shipping is arguably the oldest form of occupation of the Greeks and a key element of Greek economic activity since the ancient times. Nowadays, Greece has the largest merchant fleet in the world, which is the second largest contributor to the national economy after tourism and forms the backbone of world shipping. The Greek fleet flies a variety of flags, however some Greek shipowners gradually return to Greece following the changes to the legislative framework governing their operations and the improvement of infrastructure.Blogger Tips and Tricks

Commonly known simply as the shuttle, the orbiter is both the brains and heart of NASA's Space Transportation System. Hence, the STS before the number of every shuttle flight. 
 -
About the same size and weight as a DC-9 aircraft, the orbiter contains the pressurized crew compartment (which can carry up to seven crew members), the cargo bay and the three main engines mounted on its aft end. 
-
On April 12, 1981, commander John Young and pilot Robert Crippen roared into space on the first ever shuttle mission. Twenty years earlier on April 12, 1961, cosmonaut Yuri Gagarin ushered in the era of human space flight when he became the first person to orbit the Earth.

NATO must fight harder against Gaddafi’s forces..[ 2240 ]


France, Britain want NATO to fight harder against Gaddafi’s forces

PARIS — Thirteen days after the United States turned over command of the Libya campaign, the NATO alliance showed signs of strain Tuesday, with France and Britain complaining that their partners are not doing enough to help protect rebel-held cities from assaults by Moammar Gaddafi’s troops.

.

The unusual open criticism, from French Foreign Minister Alain Juppe and British Foreign Secretary William Hague, raised questions about the ability of the 28-member alliance to smoothly conduct a large-scale, sustained military operation without the United States playing a commanding role, as it has in the past.
“The Americans have the numbers of planes, and the Americans have the right equipment,” said Francois Heisbourg, a military specialist at the Foundation for Strategic Research in Paris.
But the Obama administration appeared to reject the possibility of an expanded U.S. military role in the near future. A State Department spokesman insisted Tuesday that NATO was performing adequately in enforcing the no-fly zone, and said the alliance was fine-tuning its tactics to address complaints about the campaign’s effectiveness.
“We have every confidence in NATO’s ability to carry out the task of enforcing the arms embargo as well as the no-fly zone and the protection of civilians in Libya,” the spokesman, Mark Toner, told reporters in Washington.
.
“The U.S., of course, as needed, would help out if requested in other capacities. But, really, our role has receded,” he said.
Juppe and Hague, in separate comments, urged more NATO countries to dispatch aircraft ready to participate actively in the bombing operations. A European official who spoke on the condition of anonymity because of the sensitivity of the issue said Hague was speaking in particular of restrictions imposed by most contributing governments that have limited many NATO warplanes to secondary roles.
.
“We must maintain and expand our efforts in NATO,” Hague said upon arriving in Luxembourg for a European Union meeting. “That is why the United Kingdom in the last weeks supplied additional aircraft capable of striking ground targets that threaten the civilian population. Of course, it would be welcome if other countries did the same.”
Juppe, in even more direct remarks on France Info radio before departing for the Luxembourg meeting, also said NATO must increase the effectiveness of its bombing operations. That would help prevent Gaddafi’s forces from shelling the besieged city of Misurata and other contested cities.
“NATO wanted to take over military operations, and we accepted that,” Juppe said. “But it must play its full role. That is to say, it must prevent Gaddafi from using heavy weapons against the civilian population.”
What NATO is doing now, he added, “is not sufficient.”
.
‘Not enough aircraft’
Seventeen nations, with about 175 planes, have been officially participating in the NATO campaign since the United States stepped back March 31. Of those, only France and Britain are allowing their aircraft to fly without restrictions on their use, noted Jean-Pierre Maulny, a defense expert at the International and Strategic Relations Institute in Paris. Of the other aircraft, some have been barred from bombing, others from hitting vehicles and others from flying attack missions at all, according to reports from Brussels.
But Brig. Gen. Mark van Uhm, NATO’s Dutch chief of allied operations, told reporters at NATO headquarters in Brussels that bombing operations have not dropped off since the United States handed over the command and withdrew most of its aircraft from the campaign. Over the past week, he said, the number of sorties — one flight by one plane — has averaged 155, of which 62 were strike missions.
.
Seeking to refute criticism that the campaign has become ineffective in protecting rebel-held cities, van Uhm said NATO aircraft destroyed 49 Libyan army tanks and nine armored personnel carriers over the weekend alone, most of them near the contested eastern city of Ajdabiya. The airstrikes were credited by rebels with helping halt a Libyan army assault on the strategic crossroads town, 99 miles south of rebel headquarters in Benghazi.
.
“I think with the assets we have, we are doing a great job,” he said.
NATO’s performance in running the air campaign was expected to be a key topic at a meeting of NATO foreign ministers in Germany later this week. Secretary of State Hillary Rodham Clinton was scheduled to fly to Berlin on Wednesday for two days of talks, while the department’s top Middle East experts huddled with European and Arab counterparts and Libyan opposition leaders in the Persian Gulf state of Qatar to map out strategy.
-
Some NATO officials have suggested that their bombing would be more effective if the U.S. A-10 Warthog close-support plane were made available again, Heisbourg said, because none of NATO’s other air forces possess similar slow-flying warplanes.
“The essence of the problem,” he added, “is not enough aircraft and not enough of the right kind of aircraft.”
The pilots of France’s Rafale and Mirage 2000 fighter-bombers, for instance, have found their Sagem AASM 125 air-to-ground missile systems to be remarkably effective in striking Libyan tanks, he noted. But the problem is that they are fired from high up and Gaddafi’s forces have adopted the same ragtag uniforms and four-wheel-drive pickups as the rebels to blend into the desert landscape.
“If it’s a tank down there, it’s okay,” Heisbourg said. But the missiles “certainly can’t tell the difference between a rebel Toyota pickup and a loyalist Toyota pickup,” he added.
-
French objections
Juppe’s comments carried a particular edge because French President Nicolas Sarkozy’s government strongly opposed turning operations over to a NATO command after the Obama administration decided to reduce its commitment at the end of March.
The ostensible French argument was that Arab governments would oppose any operation carried out with the NATO brand name. But its unsaid goal was to keep the command in the hands of the main combatants, France and Britain.
Sarkozy had to acquiesce to a NATO command, however, under pressure from the United States and Britain. Against that background, French officials began complaining that the campaign was bogging down within days of the U.S. withdrawal.
.
The unease grew as reports from Libya made it clear that rebel forces — which seemed to be winning as NATO took over — were in no shape to quickly overwhelm Gaddafi’s army and well-equipped militias.
A senior French diplomat, speaking anonymously to avoid committing the government, emphasized that France and its allies are relying on defections among Gaddafi’s aides and on diplomacy to bring the campaign to an end, realizing that the early hope of a clean rebel victory has evaporated.
Whatever the method, he said, France and its allies have decided the outcome must be Gaddafi’s departure from power.
-
Former Libyan foreign minister Musa Kusa, who abandoned Gaddafi late last month and fled to Britain, was set to leave Tuesday for the international meeting on Libya scheduled for Wednesday in Qatar, according to a person familiar with the matter who was not authorized to speak publicly. The trip would mark Kusa’s first since his defection, and he appeared set to offer insights on Libya to officials gathering for the forum in Doha.
-
U.S. officials confirmed that Musa Kusa had been invited to the Doha meeting by the host country, but said it was not clear what role, if any, the former Libyan intelligence chief would play in the meeting.

In this image from 2005, NASA's Mars Exploration Rover Opportunity used its rock abrasion tool on a rock informally named "Gagarin" during the 401st and 402nd Martian days, or sols, of the rover's work on Mars (March 10 and 11, 2005). 
-
This false-color image shows the circular mark created where the tool exposed the interior of the rock Gagarin at a target called "Yuri." 
 -
The circle is about 1.8 inches (4.5 centimeters) in diameter. Gagarin is at the edge of a highly eroded, small crater that was informally named Vostok for the spacecraft that carried Cosmonaut Yuri Gagarin in the first human spaceflight, on April 12, 1961.
 -
This image combines exposures taken through three different filters by Opportunity's panoramic camera on Sol 405 (March 14, 2005). The view is presented in false color to emphasize differences among materials in the rocks and the soils.

Japan: Eearthquake 7.1 hits north-east..[ 2238 ]

Japan: Powerful earthquake hits north-east




A powerful earthquake has hit north-east Japan, exactly one month after the devastating earthquake and tsunami.

The 7.1-magnitude tremor triggered a brief tsunami warning, and forced workers to evacuate the crippled Fukushima nuclear plant.
The epicentre of the quake was in Fukushima prefecture, and struck at a depth of just 10km (six miles).
It came as Japan said it was extending the evacuation zone around the nuclear plant because of radiation concerns.

A house of cards..[ 2237 ]

A society that depends on nuclear energy is just like a house of cards

(Mainichi Japan) April 9, 201

A tsunami triggered by the March 11 Great East Japan Earthquake not only destroyed towns and ports in northeastern Honshu, but also demonstrated various problems involving Japan's post-war energy policy.
The nuclear power policy that the government had disguised as rock-solid has actually proved so vulnerable. Prosperity built around such a policy is fragile. This has illustrated a wide perception gap between people on the seriousness of the crisis.
Even though people are calling for solidarity and collective efforts to overcome the disaster, nobody apparently has the impression that the groundwork has been laid for the restoration of Japan.
Late last week, I visited quake- and tsunami-ravaged areas in the Sanriku district along the Pacific coast of the Tohoku region -- Rikuzen-Takata in Iwate Prefecture, Kesennuma, Minami-Sanriku and Ishinomaki in Miyagi Prefecture, as well as the Fukushima Prefecture city of Soma. Many of these areas have been left in ruins. A large part of Kesennuma has been reduced to ashes by quake-triggered fires.
In sharp contrast, inland areas of quake-hit cities and towns remain intact. Residents of the Tokyo metropolitan area are losing their sense of crisis. No wonder that there is a wide perception gap on the seriousness of the disaster.
In an interview, former Fukushima Gov. Eisaku Sato emphasized that the nuclear accident is a man-made disaster. Sato, 71, is known as a staunch opponent of nuclear power generation.

The former governor pointed out that the biggest problem involving the national government's nuclear power policy is that bureaucrats and power suppliers are under the wrong impression that nuclear power generation is absolutely safe and should be promoted by all means and that they keep problems involving such plants a secret. He thus asserted that efforts to invite electric power companies to build nuclear power plants in sparsely populated areas in a bid to create jobs for local residents are nothing but addictive drugs for regional communities.
Sato served five terms as governor from 1988. Initially, he promoted the introduction of nuclear power plants, but a wide gap emerged between him and the national government as well as Tokyo Electric Power Co. (TEPCO), the operator of the tsunami-crippled Fukushima No. 1 Nuclear Power Plant. After he resigned during his fifth tenure, he was arrested for accepting bribes and later indicted. He was convicted by the district and high courts, and has appealed the ruling to the Supreme Court.
It is inappropriate to jump to the conclusion that he was arrested as a result of a politically motivated investigation aimed at suppressing anti-nuclear power movements, but what he pointed out has been proven by various news reports.
The government's Nuclear and Industrial Safety Agency (NISA) learned that a U.S. research institute had pointed to the possibility that the loss of an electric power source could lead to a reactor core meltdown, but disregarded it. The Fukushima Prefecture town of Futaba, which hosts the plant's No. 5 and 6 reactors, still suffers from huge budget deficits even though 30 years have passed since the power station was built.
A historian who heard inconsistent announcements that the government and TEPCO made in their separate news conferences said the crisis is just like the "Nomonhan Incident," an armed conflict that broke out between Japanese and Soviet forces along the border between Mongolia and Manchuria, currently part of northeastern China, in 1939. Japan, which was overconfident of its military might after its victory in the Japanese-Russo War, underestimated Russia and went into another armed conflict with it. Even though Japanese soldiers on the battlefront were outstanding, Japan suffered a humiliating defeat because of inadequate instructions given by elite officers who did not know actual warfare.
The Japanese military covered up their defeat in the battle, and fought in the Pacific War without analyzing the cause of its failure in the incident, leading to its catastrophic defeat in World War II.
The Nomonhan incident raised questions as to whether Japan should seek to restore disaster-ravaged areas under the leadership of elite bureaucrats -- who were overly proud of Japan's prosperity as an economic and technological superpower -- without clarifying the cause of their mistake that led to the crisis.

At the time of the Nomonhan Incident, the Cabinet of Prime Minister Kiichiro Hiranuma was unable to control the Imperial Japanese Army and he was forced to step down after being tossed about in a complex international situation.
There are now calls urging the two major political parties -- the Democratic Party of Japan and the Liberal Democratic Party -- to form a grand coalition in order to facilitate their cooperation in overcoming the disaster. However, there is no point in forming a large ruling bloc that cannot control bureaucrats.
At Rikuzen-Takata, which has been left in ruin, work is under way to install new utility polls along National Route 45. The public has agreed that it is an urgent task to quickly restore utilities, but there is no consensus about a vision on what kind of society should be created after rebuilding destroyed infrastructure.
The crisis has clarified that a society that depends heavily on electricity generated largely by nuclear power plants -- which Japan as a post-war economic and technological superpower has achieved -- is just like a house of cards. Japanese leaders as well as members of the general public should be aware of this. (By Takao Yamada, Expert Senior Writer)
