In computing and telecommunications, a character is a unit of information that roughly corresponds to a grapheme, grapheme-like unit, or symbol, such as in an alphabet or syllabary in the written form of a natural language. That is to say, roughly, it is a unit of information that encodes a character (symbol).
Radar astronomy is a technique of observing nearby astronomical objects by reflecting radio waves or microwaves off target objects and analyzing their reflections. Radar astronomy differs from radio astronomy in that the latter is a passive observation and the former an active one. Radar systems have been conducted for six decades applied to a wide range of Solar System studies. The radar transmission may either be pulsed or continuous. The strength of the radar return signal is proportional to the inverse fourth-power of the distance. Upgraded facilities, increased transceiver power, and improved apparatus have increased observational opportunities.
The Goldstone Deep Space Communications Complex (GDSCC), commonly called the Goldstone Observatory, is a satellite ground station located in Fort Irwin in the U.S. state of California. Operated by NASA's Jet Propulsion Laboratory (JPL), its main purpose is to track and communicate with interplanetary space missions. It is named after Goldstone, California, a nearby gold-mining ghost town.
Richard Joseph Goldstone is a South African retired judge who served in the Constitutional Court of South Africa from July 1994 to October 2003. He joined the bench as a judge of the Supreme Court of South Africa, first in the Transvaal Provincial Division from 1980 to 1989 and then in the Appellate Division from 1990 to 1994. Before that, he was a commercial lawyer in Johannesburg, where he entered legal practice in 1963 and took silk in 1976.
Chao Meng-Fu is a 167 km (104 mi) diameter crater on Mercury named after the Chinese painter and calligrapher Zhao Mengfu (1254–1322). Due to its location near Mercury's south pole and the planet's small axial tilt, an estimated 40% of the crater lies in permanent shadow. This combined with bright radar echoes from the location of the crater leads scientists to suspect that it may shelter large quantities of ice protected against sublimation into the near-vacuum by the constant −171 °C (−276 °F) temperatures.
The Goldstone Ground was a football stadium in Hove, East Sussex that was the home ground of Brighton & Hove Albion between 1902 and 1997.
Jack A. Goldstone is an American sociologist, political scientist, and historian, specializing in studies of social movements, revolutions, political demography, and the 'Rise of the West' in world history. He is an author or editor of 13 books and over 150 research articles. He is recognized as one of the leading authorities on the study of revolutions and long-term social change.
Arecibo Catena is a catena on Mercury. It is named after Arecibo Observatory, the former large radio telescope in Puerto Rico.
Haystack Catena is a catena on Mercury. It superficially resembles a graben but is a chain of overlapping secondary craters. It is named after Haystack Observatory, and was originally named Haystack Vallis when it was imaged by Mariner 10 in 1974, but the name was changed in 2013 to better reflect its origin. It is approximately 274 km long. It is located near the center of the Kuiper quadrangle, and it is radial to a large, unnamed crater that is Tolstojan in age.
The Kuiper quadrangle, located in a heavily cratered region of Mercury, includes the young, 55-km-diameter crater Kuiper, which has the highest albedo recorded on the planet, and the small crater Hun Kal, which is the principal reference point for Mercurian longitude. Impact craters and basins, their numerous secondary craters, and heavily to lightly cratered plains are the characteristic landforms of the region. At least six multiringed basins ranging from 150 km to 440 km in diameter are present. Inasmuch as multiringed basins occur widely on that part of Mercury photographed by Mariner 10, as well as on the Moon and Mars, they offer a potentially valuable basis for comparison between these planetary bodies.
The Manned Space Flight Network was a set of tracking stations built to support the American Mercury, Gemini, Apollo, and Skylab space programs.
Tractus Catena is a set of pits in the Arcadia quadrangle of Mars. Its location is centered at 28.17°N 102.77°W. It is 897 km (557 mi) long and was named after a classical albedo feature name. The term "Catena" refers to a chain of craters.
The United Nations Fact Finding Mission on the Gaza Conflict, also known as the Goldstone Report, was a United Nations fact-finding mission established in April 2009 pursuant to Resolution A/HRC/RES/S-9/1 of the United Nations Human Rights Council (UNHRC) of 12 January 2009, following the Gaza War as an independent international fact-finding mission "to investigate all violations of international human rights law and international humanitarian law by the occupying Power, Israel, against the Palestinian people throughout the Occupied Palestinian Territory, particularly in the occupied Gaza Strip, due to the current aggression". South African jurist Richard Goldstone was appointed to head the mission. The other co-authors of the Report were Hina Jilani, Christine Chinkin and Desmond Travers.
Hokusai is a rayed impact crater on Mercury, which was discovered in 1991 by ground-based radar observations conducted at Goldstone Observatory. The crater was initially known as feature B. Its appearance was so dissimilar to other impact craters that it was once thought to be a shield volcano. However, improved radar images by the Arecibo Observatory obtained later in 2000–2005 clearly showed that feature B is an impact crater with an extensive ray system. The bright appearance of rays in the radio images indicates that the crater is geologically young; fresh impact ejecta has a rough surface, which leads to strong scattering of radio waves.
Debussy is a rayed impact crater on Mercury, which was discovered in 1969 by low resolution ground-based radar observations obtained by the Goldstone Observatory. Later in 1990–2005 it was imaged in more detail by the Arecibo Observatory. The crater was initially known as the feature A. The bright appearance of rays in the radar images indicates that the crater is geologically young, because fresh and rough surfaces of young impact craters are good scatterers of radio waves.
Chaikovskij is a crater on Mercury. It has a diameter of 171 kilometers. Its name was adopted by the International Astronomical Union (IAU) in 1976. Chaikovskij is named for the Russian composer Pyotr Ilyich Tchaikovsky, who lived from 1840 to 1893.
The Goldstone Solar System Radar (GSSR) is a large radar system used for investigating objects in the Solar System. Located in the desert near Barstow, California, it comprises a 500-kW X-band transmitter and a low-noise receiver on the 70-m DSS 14 antenna at the Goldstone Deep Space Communications Complex. It has been used to investigate Mercury, Venus, Mars, the asteroids, and moons of Jupiter and Saturn. The most comparable facility was the radar at Arecibo Observatory, until that facility collapsed.
Robert Ian Goldstone is a British publicist, music manager, and former tabloid journalist who gained international attention for his activities during the 2016 American presidential election campaign.
A meeting took place at Trump Tower in New York City on June 9, 2016, between three senior members of the 2016 Trump campaign – Donald Trump Jr., Jared Kushner, and Paul Manafort – four other U.S. citizens, and Russian lawyer Natalia Veselnitskaya. The meeting was arranged by publicist and long-time Trump acquaintance Rob Goldstone on behalf of his client, Russian singer-songwriter Emin Agalarov. The meeting was first disclosed to U.S. government officials in April 2017, when Kushner filed a revised version of his security clearance form.
