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

A rocket from California..[ 2020 ]


Huge Delta rocket flies from Vandenberg, California



Delta-4 Heavy (Pat Corkery/United Launch Alliance)  
Three years' work has gone into preparing the pad and support facilities to accommodate the Delta
The biggest rocket ever to launch from the US West Coast has lifted off from Vandenberg Air Force Base.
The 72m-high Delta IV Heavy was carrying a classified satellite for the National Reconnaissance Office (NRO).
It has previously only operated from Florida, and the launch pad at the Californian base had to be upgraded to handle the giant vehicle.
Flying the Delta from the West Coast allows the largest reconnaissance satellites to be put into polar orbits.
.
The vehicle is reserved for military and intelligence use, although there has long been discussion about modifying it for a role in human spaceflight.
The Delta IV Heavy features three core boosters strapped side by side. Each has a Pratt and Whitney Rocketdyne-built RS-68 engine.
These motors burn a tonne of propellant every second and produce 2,900 kiloNewtons (650,000lbs) of thrust at lift-off.
.
This was the fifth flight in the vehicle's history, and the second in just two months.
No details were released about the payload. The NRO operates satellites that return information to the Central Intelligence Agency and US Department of Defence. Large imaging satellites of the type the Delta IV could launch would have remarkable resolution.

The rocket is reserved for government use
Vandenberg's position on the coast means the Delta can fly south over the Pacific and avoid crossing land as it climbs skyward.
.
The last heavy-lift rocket to launch from Vandenberg was the Titan IV-B in 2005.
The extra performance of the Delta enables it to put a further tonne of payload into low-earth orbit compared with the Titan.
.
Thursday's launch took place at 1310 Pacific Standard Time (1610 EST; 2110 GMT). Some $100m had been spent upgrading the SLC-6 launch pad.

Canada to Show Movie About Iran..[ 2018 ]

Despite Threats, Canada to Show Movie About Iran

By Edmund DeMarche
Published January 19, 2011/ Posted 20 Jabuary 2011..17:15

When some government officials in Canada learned that a federal institution bowed to demands to cancel a documentary film about the dangers of an atomic Iran, the officials went nuclear.
James Moore, the heritage minister in Canada, told Library and Archives of Canada (LAC) to show “Iranium,” despite threats of violence leveled at the institution from those angered with the film.
“The principle of free speech is one of the cornerstones of our democracy,” Moore’s office said in a statement. “Minister Moore took action as soon as he heard that the film was cancelled."
In turn, LAC announced it will offer the viewing of the documentary film at a later date in February. 
Moore indicated that the appropriate steps will be taken to ensure security.

“This tells me that Tehran does not decide what movie is shown in Ottawa,” Alex Traiman, the director of the film told FoxNews.com. “I’m very impressed with Minister Moore and all the other people that went psycho over this protest.”
The film was supposed to be previewed at Library and Archives, a federal crown agency, on Tuesday. But the institution received a letter from the Iranian embassy asking that the film not be shown, apparently because it puts the nuclear program in a poor light.
 .
The institution decided to go forward with the screening until threatening phone calls started pouring in. After two suspicious letters arrived the day of the filming, the institution said it would not show the documentary and closed the auditorium.
When government officials caught wind of the cancellation, they responded quickly.
The National Post reported Immigration Minister Jason Kenney posting on Twitter: “The cancellation of tonight’s screening of "Iranium" is outrageous.”
 .
Moore also announced his dismay on Twitter, according to the paper, saying: “I am disappointed that Library & Archives Canada chose not to show the film tonight due to threats of violence.”
Moore went on to say, “The Iranian Embassy will not dictate to the Government of Canada which films will or will not be shown in Canada.”
"Iranium" has only had a few screenings so far in the United States. Its premiere was scheduled to take place Feb. 8 simultaneously at several American cities, according to The National Post.

The latest NASA "Image of the Day" image.

In October 2010, NASA's Marshall Space Flight Center and White Sands Test Facility worked with Pratt & Whitney Rocketdyne to successfully complete a series of thruster tests that will aid in maneuvering and landing the next generation of robotic lunar landers that could be used to explore the moon's surface and other airless celestial bodies. 
 .
he test results will allow the Robotic Lander Project to move forward with robotic lander designs using advanced propulsion technology. In this image, the Divert Attitude Control System thruster fired under vacuum conditions to simulate operation in a space environment. 
The tests mimicked the lander mission profile and operation scenarios.
