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

This 26 meter (85 foot) antenna operated in Woomera (Island Lagoon), Australia at Deep Space Station (DSS) 41, established in August 1960. The Island Lagoon site was the first deep space station to be established outside the United States and the first Australian antenna NASA built. 
.
The station was operated by the Australian Department of Supply and helped support the Ranger and early Mariner missions, as well as communications from the Deep Space Network (DSN) complex in Goldstone, California via a moon bounce. Woomera’s antenna ceased operations in 1972.
.
Today, the Deep Space Network -- consisting of three sites in Goldstone, California; Madrid, Spain; and Canberra, Australia -- supports space communications for NASA and non-NASA missions that explore the furthest points of our solar system. Each complex currently has a 70 meter (230 foot) antenna, one 34 meter (111 foot) High Efficiency (HEF) antenna, and one or more 34 meter Beam Wave Guide (BWG) antenna. 
 .
The Deep Space Network is operated 24 hours a day, seven days a week, 365 days per year. To support future mission needs, construction is currently underway in Canberra, Australia to add two new 34 meter BWG antennas, Deep Space Station 35 (DSS-35) and DSS-36 by 2018.
