Waynick * Member of USNC-URSI Executive Committee DESCRIPTION OF THE INTERNATIONAL UNION OF RADIO SCIENCE The International Union of Radio Science is one of 18 world scientific unions organized under the International Council of Scientific Unions (!CSU). It is commonly designated as URS! (from its French name, Union Radio Scientifique Internationale). Its aims are (1) to promote the scientific,study of radio communications, (2) to aid and organize radio research requiring cooperation on an international scale and to encourage the discussion and .publication of the results (3) to facilitate agreement upon common methods of measurement and"the standardization of measuring instruments, and (4} to stimulate and to coordinate studies of the scientific aspects of telecommunications using electromagnetic waves, guided and unguided. The International Union itself is an organizational frame­ work to aid in promoting these objectives. The actual technical work is largely done by the National Committees in the various countries. The officers of the International Union are: President: W. E. Gordon (USA) Past President: W. N. °Christiansen (Australia) Vice Presidents: A. L. Cullen (U.K,) A. P. Mitra (India) s. Okamura (Japan) A. Smolinski (Poland) Secretary-General: J. Van Bladel (Belgium) Honorary Presidents: H. G. Booker (USA) G. Beynon (U.K.) M. B. Decaux (France) W. Dieminger (West Germany) I. Koga (Japan) J. A. Ratcliffe (U.K.) The Secretary-General's office and the headquarters of the organization are located at Avenue de Lancaster 32, B-1180 Brussels, Belgium. The Union is supported by contributions (dues) from 38 member countries. Additional funds for symposia and other scientific activities of the Union are provided by !CSU from contributions re­ ceived for this purpose from UNESCO. The International Union, as of the XXth General Assembly held in Washington, D.C., in August 1981, has nine bodies called Commission for centralizing studies in the principal technical fields. The names of the Commissions and their chairmen follow. V A. Electromagnetic Metrology V. Kose (FRG) B. Fields and Waves H. C, Unger (FRG)' C. Signals and Systems J. K. Wolf (USA) D. Electronic and Optical Devices and Applications J, Le Mezec (France) E. Electromagnetic Noise and Interference S. Lundquist (Sweden) F. Remote Sensing and Wave Propagation D. Gjessing (Norway) G. Ionospheric Radio and Propagation P. Bauer (France) H. Waves in Plasmas M. Petit (France) J. Radio Astronomy V, Radhakrishnan (India) Every three years the International Union holds a meeting called the General Assembly; the next is the XXIst, to be held in Florence, Italy, in August/September, 1984. The Secretariat prepares and distributes the Proceedings of these General Assemblies. The International Union arranges international symposia on specific sub­ jects pertaining to the work of one or several Commissions and also cooperates with other Unions in international symposia on subjects of joint interest. Radio is unique among the fields of scientific work in having a specific adaptability to large-scale international research pro­ grams, since many of the phenomena that must be studied are world­ wide in extent and yet are in a measure subject to control by experi­ menters. Exploration of space and the extension of scientific obser­ vations to the space environment are dependent on radio for their research. One branch, radio astronomy, involves cosmic phenomena. URSI thus has a.distinct field of usefulness in furnishing a meeting ground for the numerous workers in the -manifold aspects of radio re­ search; its meetings and committee activities furnish valuable means of promoting research through exchange of ideas. vd.

The LVDC allows engineers to monitor telemetry data during unmanned rocket launches. Significance: Missile Assembly Building AE, commonly called Hangar AE, is nationally significant as the telemetry station for NASA KSC’s unmanned Expendable Launch Vehicle (ELV) program. Since 1961, the building has been the principal facility for monitoring telemetry communications data during ELV launches and until 1995 it processed scientifically significant ELV satellite payloads. Still in operation, Hangar AE is essential to the continuing mission and success of NASA’s unmanned rocket launch program at KSC. It is eligible for listing on the National Register of Historic Places (NRHP) under Criterion A in the area of Space Exploration as Kennedy Space Center’s (KSC) original Mission Control Center for its program of unmanned launch missions and under Criterion C as a contributing resource in the CCAFS Industrial Area Historic District.

According to the role-model hypothesis, the gender match between scientist and influencer is paramount (for example, women scientists would disproportionately often mention their mothers as career influencers)," scientists writing in the journal Social Studies of Science report (see also ). "According to the opportunity-structure hypothesis, the parent's educational level predicts his/her probability of being mentioned as a career influencer (that ism parents with higher educational levels would be more likely to be named). The examination of a sample of American scientists who had received prestigious postdoctoral fellowships resulted in rejecting the role-model hypothesis and corroborating the opportunity-structure hypothesis.

  • Boeing Backgrounder Inmarsat-5
    Backgrounder Defense, Space & Security P.O. Box 516 St. Louis, MO 63166 www.boeing.com Inmarsat-5 Description and Purpose: Four Boeing 702HP satellites will provide new Ka-band high-data-rate mobile communications services. Customer: Continuing a relationship which began more than three decades ago, Inmarsat, the leading provider of global mobile satellite communications services, returned to Boeing in August 2010 to order three 702HP spacecraft to provide its new Ka-band global and high-capacity satellite services. In October 2013, Inmarsat exercised the option to order one more 702HP spacecraft to add to their fleet. General Characteristics: The new satellites will join Inmarsat’s fleet of geostationary satellites that provide a wide range of voice and data services through an established global network of distributors and service providers. Imarsat-5 F1, the first of four Boeing-built Inmarsat-5 satellites, was successfully launched on December 8, 2013 and handed over to the customer on March 3, 2014. Inmarsat-5 F2 successfully launched on February 1, 2015, and was handed over to the customer on April 24, 2015. Each Inmarsat-5 satellite will carry 89 Ka-band beams that will operate in geosynchronous orbit with flexible global coverage. The satellites are designed to generate approximately 15 kilowatts of power at the start of service and approximately 13.8 kilowatts at the end of their 15-year design life. To generate such high power, each spacecraft’s two solar wings employ five panels each of ultra triple-junction gallium arsenide solar cells. The Boeing 702HP carries the xenon ion propulsion system (XIPS) for all on-orbit maneuvering.

  • By: Maddie S. It Takes 84 Earth Years for It to Complete One Orbit
    Uranus By: Maddie S. It takes 84 earth years for it to complete one orbit. It's radius is 400.1 miles. At its closest it orbits Uranus appeared to be 1.7 billion miles away. At its only a blue-green ball with farthest it orbits 1.9 billion miles a smooth surface. away. Uranus is too far away to see easily without a telescope. Uranus is the seventh planet Sometimes it is just bright from the sun. It orbits farther enough to see with the naked out, along Uranus's outer eye. ring. Uranus' high powered telescope at the Keck Observatory in Hawaii creates detailed images of Uranus. Each of Uranus' hemispheres receives 42 earth years of sunlight. Uranus' rings are a mix of large chunks of matter and fine particles of dust. One spacecraft has managed to visit Uranus but it took a little creativity to get it there. The rings orbiting Uranus are thinner than those orbiting other planets. Uranus has ten moons. Ariel is Uranus's brightest moon. The moons names are Juliet, Puck Cordelia, Ophelia, Bianca, Desdemona, Portia, Rosalind, Cressida, and Belinda. Umbriel is the darkest moon on Uranus. Uranus Uranus is so far away that for about 200 years scientists could not make out how quickly it turns on its axis. Most planets turn on their axis in such a way that they are almost upright as they move about the sun. It is the only planet with an axis tipped that way, so some think of it as a sideways planet. Like most planets, Uranus has its own natural satellites, or moons.
