Swan Reach, South Australia
Swan Reach is a river port in South Australia 127 km north-east of Adelaide on the Murray River between Blanchetown and Mannum in South Australia. It is on the left bank of the river. The Swan Reach Ferry is a cable ferry crossing operated by the state government as part of the state's road network. Swan Reach, with all parts below Lock #1, is also one of the lowest parts of the river. In 2009–2010 the river was about 1.5 metres below its normal level. In late 2022 and early 2023 the town experienced a flood with river levels not seen since the devastating flood of 1956. Homes and businesses on Victoria street were inundated, along with most of the holiday homes at Marks Landing. Widespread damage was caused. At the , Swan Reach had a population of 283. History Swan Reach was first settled in the 1850s and was originally the largest of five sheep and cattle stations in the area. It soon became one of the first riverboat ports in South Australia and was a loading port ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Stolen Generation
The Stolen Generations (also known as Stolen Children) were the children of Australian Aboriginal and Torres Strait Islander descent who were removed from their families by the Australian federal and state government agencies and church missions, under acts of their respective parliaments. The removals of those referred to as "half-caste" children were conducted in the period between approximately 1905 and 1967, although in some places mixed-race children were still being taken into the 1970s. Official government estimates are that in certain regions between one in ten and one in three Indigenous Australian children were forcibly taken from their families and communities between 1910 and 1970. The Bringing Them Home Royal Commission report (1997) described the Australian policies of removing Aboriginal children as genocide. Emergence of the child-removal policy Numerous 19th and early 20th century contemporaneous documents indicate that the policy of removing mixed-race ...

Passive Radar
Passive radar (also referred to as parasitic radar, passive coherent location, passive surveillance, and passive covert radar) is a class of radar systems that detect and track objects by processing reflections from non-cooperative sources of illumination in the environment, such as commercial broadcast and communications signals. It is a specific case of ''bistatic radar'' – passive bistatic radar (PBR) – which is a broad type also including the exploitation of cooperative and non-cooperative radar transmitters. Introduction Conventional radar systems comprise a colocated transmitter and receiver (radio), receiver, which usually share a common antenna (radio), antenna to transmit and receive. A pulsed signal is transmitted and the time taken for the pulse to travel to the object and back allows the range of the object to be determined. In a passive radar system, there is no dedicated transmitter. Instead, the receiver uses third-party transmitters in the environment and m ...

Murray Mallee
The Murray Mallee is a cereal, grain-growing and sheep-farming area in the east of the Australian state of South Australia. The name is not formally designated but is widely used to refer to an area of approximately bounded by the Murray River, River Murray on its northern and western sides, the Victoria (Australia), Victorian border on its eastern side, and up to about 50 kilometres (30 miles) south of the Mallee Highway. The formal designated name for approximately the same region is Murraylands. Details The Murray Mallee area is predominantly a vast plain of low elevation, with sandhills and gentle undulating sandy rises, interspersed by flats. The annual rainfall ranges from approximately in the north to further south. The area was very lightly populated, with marginal pastoral runs of sheep at low stocking rates, until the beginning of the 20th century. Artesian water was discovered at moderate depth, and of railways were opened, mainly in the 1910s, to make sh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Satellite
A satellite or an artificial satellite is an object, typically a spacecraft, placed into orbit around a celestial body. They have a variety of uses, including communication relay, weather forecasting, navigation ( GPS), broadcasting, scientific research, and Earth observation. Additional military uses are reconnaissance, early warning, signals intelligence and, potentially, weapon delivery. Other satellites include the final rocket stages that place satellites in orbit and formerly useful satellites that later become defunct. Except for passive satellites, most satellites have an electricity generation system for equipment on board, such as solar panels or radioisotope thermoelectric generators (RTGs). Most satellites also have a method of communication to ground stations, called transponders. Many satellites use a standardized bus to save cost and work, the most popular of which are small CubeSats. Similar satellites can work together as groups, forming constellatio ...

Observatory
An observatory is a location used for observing terrestrial, marine, or celestial events. Astronomy, climatology/meteorology, geophysics, oceanography and volcanology are examples of disciplines for which observatories have been constructed. The term ''observatoire'' has been used in French since at least 1976 to denote any institution that compiles and presents data on a particular subject (such as public health observatory) or for a particular geographic area (European Audiovisual Observatory). Astronomical observatories Astronomical observatories are mainly divided into four categories: space observatory, space-based, airborne observatory, airborne, ground-based, and underground-based. Historically, ground-based observatories were as simple as containing a mural instrument (for measuring the angle between stars) or Stonehenge (which has some alignments on astronomical phenomena). Ground-based observatories Ground-based observatories, located on the surface of Earth, are u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Space Domain Awareness
Space domain awareness is the study and monitoring of satellites orbiting the Earth. It involves the detection, tracking, cataloging and identification of artificial objects, i.e. active/inactive satellites, spent rocket bodies, or Space debris, fragmentation debris. Aims Space domain awareness accomplishes the following: * Predicting when and where a decaying space object will Atmospheric entry, re-enter the Earth's atmosphere; * Preventing a returning space object, which to radar looks like a missile, from triggering a false alarm in missile-attack warning sensors; * Charting the present position of space objects and plot their anticipated orbital paths; * Detecting new human-made objects in space; * Producing a running catalogue of human-made space objects; * Determining which country owns a re-entering space object; * Informing countries whether or not objects may interfere with satellites and International Space Station orbits; * Providing data for future Anti-satellite wea ...

Light Pollution
Light pollution is the presence of any unwanted, inappropriate, or excessive artificial Visible spectrum, lighting. In a descriptive sense, the term ''light pollution'' refers to the effects of any poorly implemented lighting sources, during the day or night. Light pollution can be understood not only as a phenomenon resulting from a specific source or kind of pollution, but also as a contributor to the wider, collective impact of various sources of pollution. Although this type of pollution can exist throughout the day, its effects are magnified during the night with the contrast of the sky's darkness. It has been estimated that 83% of the world's people live under light-polluted skies and that 23% of the world's land area is affected by skyglow. The area affected by artificial illumination continues to increase. A major side effect of urbanization, light pollution is blamed for compromising health, disrupting ecosystems, and spoiling aesthetic environments. Studies show that ur ...

International Dark-Sky Association
DarkSky International, formerly the International Dark-Sky Association (IDA), is a United States–based nonprofit organization incorporated in 1988 by founders David Crawford, a professional astronomer, and Tim Hunter, a physician and amateur astronomer. The mission of DarkSky is "to preserve and protect the night time environment and our heritage of dark skies through quality outdoor lighting." Light pollution is the result of outdoor lighting that is not properly shielded, allowing light shine into the eyes and night sky. Direct light that shines into the eyes is called glare, and light directed into the night sky above the horizon causes skyglow. Lighting can also cause light trespass when it enters areas where unwanted (e.g. a neighbor's yard and windows). DarkSky is the first and currently the largest organization in the dark-sky movement. Principal approach DarkSky's principal approach is to raise awareness about the value of dark, star-filled night skies and enco ...
