USNS ''Mizar'' (MA-48/T-AGOR-11/T-AK-272) was a vessel of the United States Navy. She was named after the star Mizar. Cargo ship ''Mizar'' was built as a small ice-strengthened, double hull, cargo ship of the ''Eltanin'' class on a Maritime Administration type (C1-ME2-13a) hull, by Avondale Marine Ways, Inc. from January 1957. She entered service on March 7, 1958, and served as part of the Military Sea Transportation Service (MSTS), working around Canada and Greenland, with a single voyage to Antarctica in 1961. Naval Research Laboratory The loss of the on April 10, 1963, and problems handling heavy search equipment over the side from in 1963 drove the Naval Research Laboratory (NRL) requirement for a larger, more capable ship than the usual oceanographic research type. A search for a candidate ship, capable of being modified for an inboard center well, led to selection of ''Mizar'' in late 1963. In 1964 ''Mizar's'' successful search for the sunken submarine, before modif ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mizar
Mizar is a second- magnitude star in the handle of the Big Dipper asterism in the constellation of Ursa Major. It has the Bayer designation ζ Ursae Majoris ( Latinised as Zeta Ursae Majoris). It forms a well-known naked eye double star with the fainter star Alcor, and is itself a quadruple star system. The Mizar and Alcor system lies about 83 light-years away from the Sun, as measured by the Hipparcos astrometry satellite, and is part of the Ursa Major Moving Group. Nomenclature ''ζ Ursae Majoris'' ( Latinised to ''Zeta Ursae Majoris'' and abbreviated to ζ UMa or Zeta UMa) is Mizar's Bayer designation. It also has the Flamsteed designation 79 Ursae Majoris. The traditional name ''Mizar'' derives from the Arabic ' ' meaning 'apron; wrapper, covering, cover'. In 2016, the International Astronomical Union organized a Working Group on Star Names (WGSN) to catalog and standardize proper names for stars. The WGSN's first bulletin of July 2016 ...

Mid-Atlantic Ridge
The Mid-Atlantic Ridge is a mid-ocean ridge (a divergent or constructive plate boundary) located along the floor of the Atlantic Ocean, and part of the longest mountain range in the world. In the North Atlantic, the ridge separates the North American from the Eurasian Plate and the African Plate, north and south of the Azores Triple Junction respectively. In the South Atlantic, it separates the African and South American plates. The ridge extends from a junction with the Gakkel Ridge (Mid-Arctic Ridge) northeast of Greenland southward to the Bouvet Triple Junction in the South Atlantic. Although the Mid-Atlantic Ridge is mostly an underwater feature, portions of it have enough elevation to extend above sea level, for example in Iceland. The ridge has an average spreading rate of about per year. Discovery A ridge under the northern Atlantic Ocean was first inferred by Matthew Fontaine Maury in 1853, based on soundings by the USS ''Dolphin''. The existence of the ridge ...

National Defense Reserve Fleet
The National Defense Reserve Fleet (NDRF) consists of ships of the United States of America, mostly merchant vessels, that have been "mothballed" but can be activated within 20 to 120 days to provide shipping during national military emergencies, or non-military emergencies such as commercial shipping crises. The NDRF is managed by the U.S. Department of Transportation's Maritime Administration (MARAD). It is distinct from the United States Navy reserve fleets, which consist largely of warships. NDRF vessels are at the fleet sites at James River, Virginia ( James River Reserve Fleet); Beaumont, Texas ( Beaumont Reserve Fleet); and Suisun Bay, California (Suisun Bay Reserve Fleet); and at designated outported berths. Former anchorage sites included Stony Point, New York ( Hudson River Reserve Fleet); Wilmington, North Carolina; Mobile, Alabama; Astoria, Oregon; and Olympia, Washington. Through the 2010s, the oldest, most decrepit hulls at Suisun Bay were stripped of toxic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Military Sealift Command
Military Sealift Command (MSC) is an organization that controls the replenishment and military transport ships of the United States Navy. Military Sealift Command has the responsibility for providing sealift and ocean transportation for all US military services as well as for other government agencies. It first came into existence on 9 July 1949 when the Military Sea Transportation Service (MSTS) became solely responsible for the Department of Defense's ocean transport needs. The MSTS was renamed the Military Sealift Command in 1970. Military Sealift Command ships are made up of a core fleet of ships owned by the United States Navy and others under long-term-charter augmented by short-term or voyage-chartered ships. During a time charter MSC takes control of a merchant ship and operates it for the chartered amount of time. During this time the ship is crewed by civilian mariners and MSC pays for all expenses. Time chartered ships are not subject to inspections from foreign gove ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SOSUS
The Sound Surveillance System (SOSUS) was a submarine detection system based on passive sonar developed by the United States Navy to track Soviet Navy, Soviet submarines. The system's true nature was classified with the name and acronym SOSUS themselves classified. The unclassified name ''Project Caesar'' was used to cover the installation of the system and a cover story developed regarding the shore stations, identified only as a Naval Facility (NAVFAC), being for oceanographic research. In 1985, as the fixed bottom arrays were supplemented by the mobile Surveillance Towed Array Sensor System (SURTASS) and other new systems were coming on line, the name itself changed to Integrated Undersea Surveillance System (IUSS). The commands and personnel were covered by the "oceanographic" term until 1991 when the mission was declassified. As a result, the commands, Oceanographic System Atlantic and Oceanographic System Pacific became Undersea Surveillance Atlantic and Undersea Surveillance ...

Palomares, Almería
Palomares is an agricultural, fishing, and tourist town along the Mediterranean Sea in the Almería province of Andalusia, Spain. It is about above sea level. The village falls within the municipality of Cuevas del Almanzora. The ruins of ''El Artial'' lie just outside the village. Crashes of a B-52 and a KC-135 in 1966 The town is noted for a fatal accident in 1966 in which a B-52 Stratofortress of the Strategic Air Command crashed after a midair collision with a KC-135 Stratotanker plane, causing radioactive contamination after its payload of four hydrogen bombs (H-bombs) was dispersed and crashed. There were four thermonuclear weapons in the bomber. The high-explosive igniters in two of these bombs detonated on impact, spreading radioactive material, including deadly plutonium-239, over a wide area of the Spanish countryside, but safety mechanisms and electronics prevented nuclear explosions. The third H-bomb landed via parachute into a stream, where it was relatively intact a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1966 Palomares B-52 Crash
The 1966 Palomares B-52 crash, also called the Palomares incident, occurred on 17 January 1966, when a B-52G bomber of the United States Air Force's Strategic Air Command collided with a KC-135 tanker during mid-air refueling at over the Mediterranean Sea, off the coast of Spain. The KC-135 was destroyed when its fuel load ignited, killing all four crew members. The B-52G broke apart, killing three of the seven crew members aboard. At the time of the accident, the B-52G was carrying four B28FI Mod 2 Y1 thermonuclear (hydrogen) bombs, all of which fell to the surface. Three were found on land near the small fishing village of Palomares in the municipality of Cuevas del Almanzora, Almería, Spain. The non-nuclear explosives in two of the weapons detonated upon impact with the ground, resulting in the contamination of a area with radioactive plutonium. The fourth, which fell into the Mediterranean Sea, was recovered intact after a search lasting two and a half months. Acci ...
