Pegasus Field
Pegasus Field was an airstrip in Antarctica, the southernmost of three airfields serving McMurdo Station. It closed due to excessive melting in the summer season caused by warmer temperatures combined with dust and dirt blown in from nearby Black Island. The last flight was on December 8, 2016 and it was replaced by Phoenix Airfield with flights expected to start in February 2017. Pegasus was originally conceived as a blue ice runway capable of handling wheeled aircraft year-round, but as it was developed, it was enhanced with a 4-inch layer of compacted snow on top—thus more properly characterizing it as a white ice runway. Other local runways are the snow runways at Williams Field that are limited to ski-equipped aircraft, and the Ice Runway on the sea-ice available during the summer Antarctic field season. The field is named after ''Pegasus'', a C-121 Lockheed Constellation that made a forced landing on unprepared terrain in bad weather on October 8, 1970. None of the ...

McMurdo Station
McMurdo Station is a United States Antarctic research station on the south tip of Ross Island, which is in the New Zealand-claimed Ross Dependency on the shore of McMurdo Sound in Antarctica. It is operated by the United States through the United States Antarctic Program (USAP), a branch of the National Science Foundation. The station is the largest community in Antarctica, capable of supporting up to 1,258 residents, and serves as one of three year-round United States Antarctic science facilities. All personnel and cargo going to or coming from Amundsen–Scott South Pole Station first pass through McMurdo. By road, McMurdo is 3 kilometres (1.9 mi) from New Zealand's smaller Scott Base. History The station takes its name from its geographic location on McMurdo Sound, named after Lieutenant Archibald McMurdo of . The ''Terror'', commanded by Irish explorer Francis Crozier, along with expedition flagship ''Erebus'' under command of James Clark Ross, first charted the area ...

Lockheed Constellation
The Lockheed Constellation ("Connie") is a propeller-driven, four-engined airliner built by Lockheed Corporation starting in 1943. The Constellation series was the first pressurized-cabin civil airliner series to go into widespread use. Its pressurized cabin enabled commercial passengers to fly well above most bad weather for the first time, thus significantly improving the general safety and ease of air travel. Several different models of the Constellation series were produced, although they all featured the distinctive triple-tail and dolphin-shaped fuselage. Most were powered by four 18-cylinder Wright R-3350 Duplex-Cyclones. In total, 856 were produced between 1943 and 1958 at Lockheed's plant in Burbank, California, and used as both a civil airliner and as a military and civilian cargo transport. Among their famous uses was during the Berlin and the Biafran airlifts. Three served as the presidential aircraft for Dwight D. Eisenhower, one of which is featured at the National M ...

Airports In The Ross Dependency
An airport is an aerodrome with extended facilities, mostly for commercial air transport. Airports usually consists of a landing area, which comprises an aerially accessible open space including at least one operationally active surface such as a runway for a plane to take off and to land or a helipad, and often includes adjacent utility buildings such as control towers, hangars and terminals, to maintain and monitor aircraft. Larger airports may have airport aprons, taxiway bridges, air traffic control centres, passenger facilities such as restaurants and lounges, and emergency services. In some countries, the US in particular, airports also typically have one or more fixed-base operators, serving general aviation. Operating airports is extremely complicated, with a complex system of aircraft support services, passenger services, and aircraft control services contained within the operation. Thus airports can be major employers, as well as important hubs for tourism and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Night-vision Goggles
A night-vision device (NVD), also known as a night optical/observation device (NOD), night-vision goggle (NVG), is an optoelectronic device that allows visualization of images in low levels of light, improving the user's night vision. The device enhances ambient visible light and converts near-infrared light into visible light which can be seen by the user; this is known as I2 ( image intensification). By comparison, viewing of infrared thermal radiation is referred to as thermal imaging and operates in a different section of the infrared spectrum. A night vision device usually consists of an image intensifier tube, a protective housing, and may have some type of mounting system. Many NVDs also include a protective sacrificial lens, mounted over the front lens (ie. objective lens) on NVDs to protect the latter from damage by environmental hazards and some can incorporate [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boeing C-17 Globemaster III
The McDonnell Douglas/Boeing C-17 Globemaster III is a large military transport aircraft that was developed for the United States Air Force (USAF) from the 1980s to the early 1990s by McDonnell Douglas. The C-17 carries forward the name of two previous piston-engined military cargo aircraft, the Douglas C-74 Globemaster and the Douglas C-124 Globemaster II. The C-17 is based upon the McDonnell Douglas YC-15, YC-15, a smaller prototype airlifter designed during the 1970s. It was designed to replace the Lockheed C-141 Starlifter, and also fulfill some of the duties of the Lockheed C-5 Galaxy. Compared to the YC-15, the redesigned airlifter differed in having swept wings, increased size, and more powerful engines. Development was protracted by a series of design issues, causing the company to incur a loss of nearly US$1.5 billion on the program's development phase. On 15 September 1991, roughly one year behind schedule, the first C-17 performed its maiden flight. The C-17 formally ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ice Runway
The Ice Runway is the principal runway for the U.S. Antarctic Program during the summer Antarctic field season due to its proximity to McMurdo Station. The other two runways in the area are the snow runway at Williams Field (NZWD) and the compacted snow runway at Phoenix Airfield (NZFX), which replaced Pegasus Field (NZPG) in 2017. The sea ice runway is capable of handling wheeled aircraft, which have included to date: Lockheed C-5 Galaxy, Lockheed C-141 Starlifter, Boeing C-17 Globemaster III, Lockheed C-130 Hercules and Lockheed P-3 Orion. In the summer season of 2009/2010 the RNZAF trialed a modified Boeing 757 operationally. The intention is to use the Boeing 757 for passenger transport, thereby freeing up capacity for C17 cargo space. The annual sea-ice runway for wheeled aircraft is constructed at the start of each season and is used until early December when the sea ice begins to break up. Subsequently flight operations are moved back to Williams Field. Pilots land ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ross Island
Ross Island is an island formed by four volcanoes in the Ross Sea near the continent of Antarctica, off the coast of Victoria Land in McMurdo Sound. Ross Island lies within the boundaries of Ross Dependency, an area of Antarctica claimed by New Zealand. History Discovery Sir James Ross discovered it in 1840, and it was later named in honour of him by Robert F. Scott. Ross Island was the base for many of the early expeditions to Antarctica. It is the southernmost island reachable by sea. Huts built by Scott's and Shackleton's expeditions are still standing on the island, preserved as historical sites. Today Ross Island is home to New Zealand's Scott Base, and the largest Antarctic settlement, the U.S. Antarctic Program's McMurdo Station. Greenpeace established World Park Base on the island and ran it for five years, from 1987 to 1992. Geography Because of the persistent presence of the ice sheet, the island is sometimes taken to be part of the Antarctic mainland. Its are ...

Williams Field
Williams Field or Willy Field is a United States Antarctic Program airfield in Antarctica. Williams Field consists of two snow runways located on approximately 8 meters (25 ft) of compacted snow, lying on top of 8–10 ft of ice, floating over 550 meters (1,800 ft) of water. The airport, which is approximately seven miles from Ross Island, serves McMurdo Station and New Zealand's Scott Base. Until the 2009–10 summer season, Williams was the major airfield for on-continent aircraft operations in Antarctica. Williams Field is named in honor of Richard T. Williams, a United States Navy equipment operator who drowned when his D-8 tractor broke through the ice on January 6, 1956. Williams and other personnel were participants in the first Operation Deep Freeze, a U.S. military mission to build a permanent science research station at McMurdo Station in anticipation of the International Geophysical Year 1957–58. Operation The skiway was typically in operation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blue-ice Area
A blue-ice area is an ice-covered area of Antarctica where wind-driven snow transport and sublimation result in net mass loss from the ice surface in the absence of melting, forming a blue surface that contrasts with the more common white Antarctic surface. Such blue-ice areas typically form when the movement of both air and ice are obstructed by topographic obstacles such as mountains that emerge from the ice sheet, generating particular climatic conditions where the net snow accumulation is exceeded by wind-driven sublimation and snow transports. Only about 1% of Antarctic ice area can be considered to be blue-ice area, but they have attracted scientific interest due to the large numbers of meteorites that accumulate on them; these meteorites either fall directly on the blue-ice area and remain there or they fall elsewhere into the ice sheet and are transported to the blue-ice area by ice flow. Additionally, ice up to 2.7 million years old has been obtained from blue-i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
