National Space Program
The National Space Program was a set of policies and organisations under the Hawke and Keating Governments created with the goals of developing a national space industry in Australia. When the Howard Government came to power in 1996 the program was abolished following the advice of the Bureau of Industry Economics. The National Space Program was generally considered a failure by most media after its demise. During its existence it was crippled by a lack of budget, and multiple white elephant projects. Background Although Australia has had space interests dating back to the Apollo program, prior to the establishment of the NSP Australia had had no unified space policy. At the time of the implementation of the program, Australia had separate space related programs under the Department of Defence, CSIRO, the Department of Transport and Communications, multiple other departments, as well as multiple private and university programs. In response to the disorganised state of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Prior to 1901, telecommunications were administered by each colony. On 1 July 1975, separate c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
L Band
The L band is the Institute of Electrical and Electronics Engineers (IEEE) designation for the range of frequencies in the radio spectrum from 1 to 2 gigahertz (GHz). This is at the top end of the ultra high frequency (UHF) band, at the lower end of the microwave range. Applications Mobile service In Europe, the Electronic Communications Committee (ECC) of the European Conference of Postal and Telecommunications Administrations (CEPT) has harmonized part of the L band (1452–1492 MHz), allowing individual countries to adopt this spectrum for terrestrial mobile/fixed communications networks supplemental downlink (MFCN SDL). By means of carrier aggregation, an LTE-Advanced or UMTS/HSDPA base station could use this spectrum to provide additional bandwidth for communications from the base station to the mobile device; i.e., in the downlink direction. In the Americas, mobile services are operated between the 1.7 GHz to 2.1 GHz range in the PCS and AWS bands. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Offset Agreement
Offsets are compensatory trade agreements, reciprocal trade agreements, between an exporting foreign company, or possibly a government acting as intermediary, and an importing entity. Offset agreements often involve trade in military goods and services and are alternatively called: industrial compensations, industrial cooperation, offsets, industrial and regional benefits, balances, ''juste retour'' or equilibrium, to define mechanisms more complex than counter-trade. Counter-trade can also be considered one of the many forms of defense offset, to compensate a purchasing country. The incentive for the exporter results from the conditioning of the core transaction to the acceptance of the offset obligation.Ianakiev, Gueorgui (2014), " Defence Offsets : Regulation and Impact on the Integration of the European Defence Equipment Market ", in Bellais, Renaud (ed) (2014), "The Evolving Boundaries of Defence : An Assessment of Recent Shifts in Defence Activities ", Emerald Group Publishi ...

Hughes Aircraft Company
The Hughes Aircraft Company was a major American aerospace and defense contractor founded on February 14, 1934 by Howard Hughes in Glendale, California, as a division of Hughes Tool Company. The company was known for producing, among other products, the Hughes H-4 Hercules ''Spruce Goose'' aircraft, the atmospheric entry probe carried by the ''Galileo'' spacecraft, and the AIM-4 Falcon guided missile. Hughes Aircraft was founded to construct Hughes' H-1 Racer world speed record aircraft, and it later modified aircraft for his transcontinental and global circumnavigation speed record flights. The company relocated to Culver City, California, in 1940 and began manufacturing aircraft parts as a subcontractor. Hughes attempted to mold it into a major military aircraft manufacturer during World War II; however, its initial military projects ended in failure, with millions of dollars in U.S. government funds expended but only three aircraft actually built, resulting in a highly publi ...

Hypersonic Speed
In aerodynamics, a hypersonic speed is one that exceeds 5 times the speed of sound, often stated as starting at speeds of Mach 5 and above. The precise Mach number at which a craft can be said to be flying at hypersonic speed varies, since individual physical changes in the airflow (like molecular dissociation and ionization) occur at different speeds; these effects collectively become important around Mach 5-10. The hypersonic regime can also be alternatively defined as speeds where specific heat capacity changes with the temperature of the flow as kinetic energy of the moving object is converted into heat. Characteristics of flow While the definition of hypersonic flow can be quite vague and is generally debatable (especially due to the absence of discontinuity between supersonic and hypersonic flows), a hypersonic flow may be characterized by certain physical phenomena that can no longer be analytically discounted as in supersonic flow. The peculiarity in hypersonic flows ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ultraviolet–visible Spectroscopy
UV spectroscopy or UV–visible spectrophotometry (UV–Vis or UV/Vis) refers to absorption spectroscopy or reflectance spectroscopy in part of the ultraviolet and the full, adjacent visible regions of the electromagnetic spectrum. Being relatively inexpensive and easily implemented, this methodology is widely used in diverse applied and fundamental applications. The only requirement is that the sample absorb in the UV-Vis region, i.e. be a chromophore. Absorption spectroscopy is complementary to fluorescence spectroscopy. Parameters of interest, besides the wavelength of measurement, are absorbance (A) or transmittance (%T) or reflectance (%R), and its change with time. Optical transitions Most molecules and ions absorb energy in the ultraviolet or visible range, i.e., they are chromophores. The absorbed photon excites an electron in the chromophore to higher energy molecular orbitals, giving rise to an excited state. For organic chromophores, four possible types of transitions ...

STS-42 Launch
STS-4 was the fourth NASA Space Shuttle mission, and also the fourth for Space Shuttle ''Columbia''. Crewed by Ken Mattingly and Henry Hartsfield, the mission launched on June 27, 1982, and landed a week later on July 4, 1982. Due to parachute malfunctions, the SRBs were not recovered. STS-4 was the final test flight for the Space Shuttle; it was thereafter officially declared to be operational. ''Columbia'' carried numerous scientific payloads during the mission, as well as military missile detection systems. Crew STS-4, being the last test flight of the Space Shuttle, was also the last to carry a crew of two astronauts. Commander Ken Mattingly had previously flown as Command Module Pilot on Apollo 16, and was also the original Command Module Pilot for Apollo 13 before being replaced by his backup, Jack Swigert. Hartsfield was a rookie astronaut who had transferred to NASA in 1969 after the cancellation of the Air Force's Manned Orbiting Laboratory (MOL) program. He ...
