Interplanetary Spaceflight
Interplanetary spaceflight or interplanetary travel is the crewed or uncrewed travel between stars and planets, usually within a single planetary system. In practice, spaceflights of this type are confined to travel between the planets of the Solar System. Uncrewed space probes have flown to all the observed planets in the Solar System as well as to dwarf planets Pluto and Ceres, and several asteroids. Orbiters and landers return more information than fly-by missions. Crewed flights have landed on the Moon and have been planned, from time to time, for Mars, Venus and Mercury. While many scientists appreciate the knowledge value that uncrewed flights provide, the value of crewed missions is more controversial. Science fiction writers propose a number of benefits, including the mining of asteroids, access to solar power, and room for colonization in the event of an Earth catastrophe. A number of techniques have been developed to make interplanetary flights more economical. Adv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NASA Deep Space Network
The NASA Deep Space Network (DSN) is a worldwide network of American spacecraft communication ground segment facilities, located in the United States (California), Spain (Madrid), and Australia (Canberra), that supports NASA's interplanetary spacecraft missions. It also performs radio and radar astronomy observations for the exploration of the Solar System and the universe, and supports selected Earth-orbiting missions. DSN is part of the NASA Jet Propulsion Laboratory (JPL). General information DSN currently consists of three deep-space communications facilities placed approximately 120 degrees apart around the Earth. They are: * the Goldstone Deep Space Communications Complex () outside Barstow, California. For details of Goldstone's contribution to the early days of space probe tracking, see Project Space Track; * the Madrid Deep Space Communications Complex (), west of Madrid, Spain; and * the Canberra Deep Space Communication Complex (CDSCC) in the Australia ...

Chinese Deep Space Network
The Chinese Deep Space Network (CDSN) is a network of large antennas and communication facilities that are used for the interplanetary spacecraft missions of China. It is managed by the China Satellite Launch and Tracking Control Center General (CLTC), which reports to the People's Liberation Army Strategic Support Force Space Systems Department. They also deal with radio-astronomical and radar observations. The network was first needed for the lunar mission Chang'e 1, and since has been used to support subsequent missions to the Moon and Mars such as Chang'e 5, and Tianwen-1 missions. Similar deep space networks are run by the United States, Russia, European countries, Japan, and India. Introduction In principle, a Chinese deep space network has existed since 1993 with the commissioning of the Nanshan 25-meter telescope in the mountains south of Ürümqi. The 25-meter antenna of the Shanghai Astronomical Observatory was then not only able to participate in the Sout ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ESA Deep Space Network
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. ESA stations Core Ground Stations * K ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Japanese Deep Space Network
Usuda Deep Space Center is a facility of the Japan Aerospace Exploration Agency. It is a spacecraft tracking station in Saku, Nagano, opened in October, 1984. The main features of the station are two large beam waveguide antennas, an older 64 meter antenna and a newer 54 meter dish. Usuda was the first deep-space antenna constructed with beam-waveguide technology. Although this construction dramatically simplifies installation and maintenance of electronics, it was previously thought to offer poor noise performance. However, after the U.S. Jet Propulsion Lab (JPL) tested this antenna and found the noise performance was better than its conventional 64-meter antennas, it too switched to this method of construction for all subsequent antennas of their Deep Space Network (DSN). Because the 64 meter antenna is aging and is still in use over ten years after its designed service life, JAXA has built a new antenna nearby. Similar huge antennas are used by the deep space networks of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indian Deep Space Network
Indian Deep Space Network (IDSN) is a network of large antennas and communication facilities operated by the Indian Space Research Organisation to support the interplanetary spacecraft missions of India. Its hub is located at Byalalu, Ramanagar in the state of Karnataka in India. It was inaugurated on 17 October 2008 by the former ISRO chairman G. Madhavan Nair. Similar networks are run by USA, China, Russia, Europe, and Japan. Introduction The network consists of the ISRO Telemetry, Tracking and Command Network (ISTRAC), augmented by a fully steerable and a DSN antenna which improves the visibility duration when compared with the existing ISTRAC system. The Indian Deep Space Network implements a baseband system adhering to Consultative Committee for Space Data Systems (CCSDS) Standards, thus facilitating cross-support among the Telemetry Tracking Command (TTC) agencies. The two antennas at the Byalalu complex have built-in support facilities. A fibre optic li ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
