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

IRIS Preps for Launch...[ 3134 ]

Spacecraft  IRIS Preps for Launch

IRIS Preps for Launch

The fully integrated spacecraft and science instrument for NASA's Interface Region Imaging Spectrograph (IRIS) mission is seen in a clean room at the Lockheed Martin Space Systems Sunnyvale, Calif. facility. The solar arrays are deployed in the configuration they will assume when in orbit. IRIS is scheduled to launch on June 26, 2013.

Understanding the interface between the photosphere and corona remains a fundamental challenge in solar and heliospheric science. The IRIS mission opens a window of discovery into this crucial region by tracing the flow of energy and plasma through the chromosphere and transition region into the corona using spectrometry and imaging.
.
IRIS is designed to provide significant new information to increase our understanding of energy transport into the corona and solar wind and provide an archetype for all stellar atmospheres. 
.
The unique instrument capabilities, coupled with state of the art 3-D modeling, will fill a large gap in our knowledge of this dynamic region of the solar atmosphere. 
.
The mission will extend the scientific output of existing heliophysics spacecraft that follow the effects of energy release processes from the sun to Earth.

Brazil, national security force to five major cities '''[ 3133 ]

Brazil sends national security force to quell protests

Brazil's government says it will deploy a national security force to five major cities after a wave of protests which has seen almost a quarter of a million people demand better public services.
Members of the national force will be sent to Rio de Janeiro, Minas Gerais, Bahia, Ceara and the capital, Brasilia.
All of the cities are hosting games in Fifa's Confederations Cup.
The announcement comes after riot police and protesters clashed in fresh protests on Tuesday in Sao Paulo.
Brazil's ministry of justice said that Recife was the only Confederations Cup host city not to request the support of the National Public Security Force (FNSP).

Brazil's National Public Security Force


  • Created in 2004 as a joint co-operation of various Brazilian public safety forces
  • Led by the police commissioner of Brazil's Federal Police
  • Deployed in cases of "social unrest and exceptional situations in Brazilian states when public order is challenged"

A source in the ministry said it would be up to local governments to decide how long the FNSP would stay.
Shops and banks in Brazil's largest city, Sao Paulo, were vandalised on Tuesday by groups of masked activists, who fought other demonstrators trying to stop the violence.
The protest was the latest in a wave of demonstrations engulfing at least a dozen cities.
Brazilian President Dilma Rousseff said she was proud that so many people were fighting for a better country.
The protests were sparked by anger at a rise in public transport fare prices in Sao Paulo on 2 June but have since mushroomed into much broader discontent with high levels of corruption, the poor state of the health and education services and the high cost of living.
They are the largest since 1992, when people took to the streets to demand the impeachment of then-President Fernando Collor de Mello.

On June 18, 1983, Sally Ride became the first American woman to fly in space when the space shuttle Challenger launched on mission STS-7.

 As one of the three mission specialists on the STS-7 mission, she played a vital role in helping the crew deploy communications satellites, conduct experiments and make use of the first Shuttle Pallet Satellite. In this image, Dr. Ride sits in the aft flight deck mission specialist's seat during deorbit preparations.
