Malargüe Station
Malargüe Station (also known as DSA 3 or Deep Space Antenna 3) is a 35-metre ESTRACK radio antenna in Argentina. It enables the European Space Agency (ESA) to communicate with spacecraft in deep space. It is located south of the town of Malargüe, Argentina. The Malargüe antenna has two sister stations, Cebreros Station, near Madrid, Spain, and New Norcia Station near New Norcia, Western Australia. The completion of this station allows ESTRACK to track deep space missions continuously. On 7 December 2011, the station's 35 m-diameter dish antenna was hoisted into place. The operation took several hours and had to wait for a calm day with no wind. The station underwent tests in 2012 and was fully operational in 2013. Malargüe Station was one of the stations providing communications, tracking and data download from the Rosetta spacecraft ''Rosetta'' was a space probe built by the European Space Agency launched on 2 March 2004. Along with ''Philae'', its lander module, ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ESTRACK
The European Space Tracking (ESTRACK) network consists of a number of ground-based space-tracking stations belonging to the European Space Agency (ESA), and operated by the European Space Operations Centre (ESOC) in Darmstadt, Germany. The stations support various ESA spacecraft and facilitate communications between ground operators and scientific probes such as XMM-Newton, Mars Express, BepiColombo, Gaia. Similar networks are run by the USA, China, Russia, Japan, and India. Composition The Core ESTRACK network is composed of seven ESA-owned ground stations and the ESTRACK Control Centre in the ESOC. Four of the stations are used for tracking satellites and launchers near Earth and three are used for tracking deep-space probes. Service contracts with commercially operated ground stations and cooperation agreements with international partners allows the network to track satellites that aren't in view of the ESA owned ground stations.

Radio
Radio is the technology of signaling and communicating using radio waves. Radio waves are electromagnetic waves of frequency between 30 hertz (Hz) and 300 gigahertz (GHz). They are generated by an electronic device called a transmitter connected to an antenna which radiates the waves, and received by another antenna connected to a radio receiver. Radio is very widely used in modern technology, in radio communication, radar, radio navigation, remote control, remote sensing, and other applications. In radio communication, used in radio and television broadcasting, cell phones, two-way radios, wireless networking, and satellite communication, among numerous other uses, radio waves are used to carry information across space from a transmitter to a receiver, by modulating the radio signal (impressing an information signal on the radio wave by varying some aspect of the wave) in the transmitter. In radar, used to locate and track objects like aircraft, ships, spacecraf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antenna (electronics)
In radio engineering, an antenna or aerial is the interface between radio waves propagating through space and electric currents moving in metal conductors, used with a transmitter or receiver. In transmission, a radio transmitter supplies an electric current to the antenna's terminals, and the antenna radiates the energy from the current as electromagnetic waves (radio waves). In reception, an antenna intercepts some of the power of a radio wave in order to produce an electric current at its terminals, that is applied to a receiver to be amplified. Antennas are essential components of all radio equipment. An antenna is an array of conductors ( elements), electrically connected to the receiver or transmitter. Antennas can be designed to transmit and receive radio waves in all horizontal directions equally (omnidirectional antennas), or preferentially in a particular direction ( directional, or high-gain, or “beam” antennas). An antenna may include components not connec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Spacecraft
A spacecraft is a vehicle or machine designed to fly in outer space. A type of artificial satellite, spacecraft are used for a variety of purposes, including communications, Earth observation, meteorology, navigation, space colonization, planetary exploration, and transportation of humans and cargo. All spacecraft except single-stage-to-orbit vehicles cannot get into space on their own, and require a launch vehicle (carrier rocket). On a sub-orbital spaceflight, a space vehicle enters space and then returns to the surface without having gained sufficient energy or velocity to make a full Earth orbit. For orbital spaceflights, spacecraft enter closed orbits around the Earth or around other celestial bodies. Spacecraft used for human spaceflight carry people on board as crew or passengers from start or on orbit (space stations) only, whereas those used for robotic space missions operate either autonomously or telerobotically. Robotic spacecraft used to support scientific re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Malargüe
Malargüe () is a city in the southwest part of province of Mendoza, Argentina, about 370 km south of the provincial capital Mendoza. It is the head town of the Malargüe Department, and it has about 27,000 inhabitants as per the . Overview The city is located in a semi-arid area. Agriculture is focused on the production of seed potato, along with minor crops such as alfalfa, onion and garlic. In the past, the local industries included oil exploration and production (now almost completely deactivated) and uranium mining. As a touristic area, Malargüe provides hotels and cabins for visitors interested in eco-tourism in the summer and skiing in the winter at the nearby resorts of Las Leñas and Los Molles. The city is known for its traditional dish, the ''chivito'' (baby goat). It hosts the annual National Festival of the Goat and the Provincial Festival of the Lamb, during the second week of January.

New Norcia Station
New Norcia Station (also known as NNO) is an ESTRACK Earth station in Australia for communication with spacecraft after launch, in low earth orbit, in geostationary orbit and in deep space. It is located south of the town of New Norcia, Western Australia. It was the first ESA deep space ground station, followed by Cebreros Station and Malargüe Station.

New Norcia, Western Australia
New Norcia () is a town in Western Australia, north of Perth, near the Great Northern Highway. It is situated next to the banks of the Moore River, in the Shire of Victoria Plains. New Norcia is the only monastic town in Australia, with its Benedictine abbey founded in 1848. The monks later founded a mission and schools for Aboriginal children. A series of Catholic colleges were created, with the school that became St Benedict's College in 1965 later gaining notoriety for being the site of sexual abuse that took place in the late 1960s and 1970s. The town has many heritage sites and places of interest. A ground station for the European Space Agency is located south of the town. Since a road bypass was complete in 2017, heavy traffic bypasses the town. History On 1 March 1846, a Benedictine mission to the local Yued Aboriginal people was started about to the north, led by the Spanish Benedictine monks Giuseppe Serra and Rosendo Salvado. Within a year the mission was moved ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phys
Physics is the natural science that studies matter, its fundamental constituents, its motion and behavior through space and time, and the related entities of energy and force. "Physical science is that department of knowledge which relates to the order of nature, or, in other words, to the regular succession of events." Physics is one of the most fundamental scientific disciplines, with its main goal being to understand how the universe behaves. "Physics is one of the most fundamental of the sciences. Scientists of all disciplines use the ideas of physics, including chemists who study the structure of molecules, paleontologists who try to reconstruct how dinosaurs walked, and climatologists who study how human activities affect the atmosphere and oceans. Physics is also the foundation of all engineering and technology. No engineer could design a flat-screen TV, an interplanetary spacecraft, or even a better mousetrap without first understanding the basic laws of physics. (. ...
