Stuhlinger Medal
The Stuhlinger Medal, whose official name is the "Ernst Stuhlinger Medal for Outstanding Achievement in Electric Propulsion", is the highest honor in the field of electric propulsion for spacecraft bestowed by the Electric Rocket Propulsion Society (ERPS), the main professional society in that field, to persons who made outstanding contributions to the science, technology or development of electric propulsion. The Stuhlinger Medal was established by the ERPS in 2005 as the "Medal for Outstanding Achievement in Electric Propulsion", then renamed after its first recipient Ernst Stuhlinger (1913–2008), the German-born American rocket scientist, shortly after his death in 2008. The medal is typically awarded every two years during the ERPS's main conference, the International Electric Propulsion Conference.

The Electric Rocket Propulsion Society (ERPS)
''The'' () is a grammatical article in English, denoting persons or things that are already or about to be mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with nouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a consonant sound, and as (homophone of the archaic pron ...

Electrically Powered Spacecraft Propulsion
Spacecraft electric propulsion (or just electric propulsion) is a type of spacecraft propulsion technique that uses electrostatic or electromagnetic fields to accelerate mass to high speed and thus generate thrust to modify the velocity of a spacecraft in orbit. The propulsion system is controlled by power electronics. Electric thrusters typically use much less propellant than chemical rockets because they have a higher exhaust speed (operate at a higher specific impulse) than chemical rockets.Choueiri, Edgar Y. (2009New dawn of electric rocket'' Scientific American'' 300, 58–65 Due to limited electric power the thrust is much weaker compared to chemical rockets, but electric propulsion can provide thrust for a longer time. Electric propulsion was first successfully demonstrated by NASA and is now a mature and widely used technology on spacecraft. American and Russian satellites have used electric propulsion for decades. , over 500 spacecraft operated throughout the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electric Rocket Propulsion Society
Electricity is the set of physical phenomena associated with the presence and motion of matter that has a property of electric charge. Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations. Various common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others. The presence of an electric charge, which can be either positive or negative, produces an electric field. The movement of electric charges is an electric current and produces a magnetic field. When a charge is placed in a location with a non-zero electric field, a force will act on it. The magnitude of this force is given by Coulomb's law. If the charge moves, the electric field would be doing work on the electric charge. Thus we can speak of electric potential at a certain point in space, which is equal to the work done by an external agent in carrying a unit of positiv ...

Ernst Stuhlinger
Ernst Stuhlinger (December 19, 1913 – May 25, 2008) was a German-American atomic, electrical, and rocket scientist. After being brought to the United States as part of Operation Paperclip, he developed guidance systems with Wernher von Braun's team for the US Army, and later was a scientist with NASA. He was also instrumental in the development of the ion engine for long-endurance space flight, and a wide variety of scientific experiments. Life Stuhlinger was born in Niederrimbach (now part of Creglingen), Württemberg, Germany. At age 23, he earned his doctorate in physics at the University of Tübingen in 1936, working with Otto Haxel, Hans Bethe and his advisor Hans Geiger. In 1939 to 1941, he worked in Berlin, on cosmic rays and nuclear physics as an assistant professor at the Berlin Institute of Technology developing innovative nuclear detector instrumentation. Despite showing promise as a scientist, in 1941 Stuhlinger was drafted as a private in the German Army and se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International Electric Propulsion Conference
The International Electric Propulsion Conference (IEPC) in its current form is a biennial academic conference in the field of electric space propulsion and hosted by the Electric Rocket Propulsion SocietyERPS. It was originally organized by the American Rocket Society (ARS) and later by the American Institute of Aeronautics and Astronautics The American Institute of Aeronautics and Astronautics (AIAA) is a professional society for the field of aerospace engineering. The AIAA is the U.S. representative on the International Astronautical Federation and the International Council of ... (AIAA) as a US-American national conference and was expanded starting in 1976 to its current international character with the joining of international space engineering societies. Currently, few hundred engineers and scientists join the conference and present and discuss the latest developments and research results regarding electric propulsion.

Robert G
The name Robert is an ancient Germanic given name, from Proto-Germanic "fame" and "bright" (''Hrōþiberhtaz''). Compare Old Dutch ''Robrecht'' and Old High German ''Hrodebert'' (a compound of '' Hruod'' ( non, Hróðr) "fame, glory, honour, praise, renown" and ''berht'' "bright, light, shining"). It is the second most frequently used given name of ancient Germanic origin. It is also in use as a surname. Another commonly used form of the name is Rupert. After becoming widely used in Continental Europe it entered England in its Old French form ''Robert'', where an Old English cognate form (''Hrēodbēorht'', ''Hrodberht'', ''Hrēodbēorð'', ''Hrœdbœrð'', ''Hrœdberð'', ''Hrōðberχtŕ'') had existed before the Norman Conquest. The feminine version is Roberta. The Italian, Portuguese, and Spanish form is Roberto. Robert is also a common name in many Germanic languages, including English, German, Dutch, Norwegian, Swedish, Scots, Danish, and Icelandic. It can ...
