Brazilian National Institute For Space Research
The National Institute for Space Research ( pt, Instituto Nacional de Pesquisas Espaciais, INPE) is a research unit of the Brazilian Ministry of Science, Technology and Innovations, the main goals of which are fostering scientific research and technological applications and qualifying personnel in the fields of space and atmospheric sciences, space engineering, and space technology. While INPE is the civilian research center for aerospace activities, the Brazilian Air Force's General Command for Aerospace Technology is the military arm. INPE is located in the city of São José dos Campos, São Paulo. History On August 13, 1961, President Jânio Quadros signed a decree which created the Organizing Group for the National Commission on Space Activities (COGNAE). This group would give rise to the current National Institute for Space Research. COGNAE, which shortly after became known as CNAE, started its activities by stimulating, coordinating and supporting studies on space re ...

Outer Space
Outer space, commonly shortened to space, is the expanse that exists beyond Earth and its atmosphere and between celestial bodies. Outer space is not completely empty—it is a near-perfect vacuum containing a low density of particles, predominantly a plasma of hydrogen and helium, as well as electromagnetic radiation, magnetic fields, neutrinos, dust, and cosmic rays. The baseline temperature of outer space, as set by the background radiation from the Big Bang, is . The plasma between galaxies is thought to account for about half of the baryonic (ordinary) matter in the universe, having a number density of less than one hydrogen atom per cubic metre and a kinetic temperature of millions of kelvins. Local concentrations of matter have condensed into stars and galaxies. Studies indicate that 90% of the mass in most galaxies is in an unknown form, called dark matter, which interacts with other matter through gravitational but not electromagnetic forces.

President Of Brazil
The president of Brazil ( pt, Presidente do Brasil), officially the president of the Federative Republic of Brazil ( pt, Presidente da República Federativa do Brasil) or simply the ''President of the Republic'', is the head of state and head of government of Brazil. The president leads the executive branch of the federal government and is the commander-in-chief of the Brazilian Armed Forces. The presidential system was established in 1889, upon the proclamation of the republic in a military coup d'état against Emperor Pedro II. Since then, Brazil has had six constitutions, three dictatorships, and three democratic periods. During the democratic periods, voting has always been compulsory. The Constitution of Brazil, along with several constitutional amendments, establishes the requirements, powers, and responsibilities of the president, their term of office and the method of election. Jair Bolsonaro is the 38th and current president. He was sworn in on 1 January 2019 followin ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

China–Brazil Earth Resources Satellite Program
The China–Brazil Earth Resources Satellite program (CBERS) is a technological cooperation program between Brazil and China which develops and operates Earth observation satellites. History The basis for the space cooperation between China and Brazil was established in May 1984, when both countries signed a complementary agreement to the cooperation framework agreement in science and technology. In July 1988, China and Brazil signed the protocol establishing the joint research and production of the China-Brazil Earth Resources Satellites (CBERS). Brazil, emerging from a long military regime, sought to abandon the Cold War logic and establish new international partnerships. China was dedicated to its great internal reform, but was also seeking international partnerships to develop advanced technologies. The agreement was advantageous for both countries. Brazil had the chance to develop medium-size satellites at a time when it was only capable of building small ones (100 kg size ...

Brazilian Space Program
The Brazilian space program is the rocketry and space exploration programs conducted by Brazil from 1961 until the creation of the Brazilian Space Agency in 1994. It had significant capabilities in launch vehicles, launch sites, and satellite manufacturing. It was based at the National Institute for Space Research (INPE), under the Ministry of Science and Technology (MCT). The program was under complete military control, which hindered its development, as other countries (such as the United States) blocked technological development due to concerns over missile proliferation. In 1994, the space program was transferred to civilian control under the Brazilian Space Agency. History Since 1964, in an attempt to build a satellite launch vehicle ( ''Veículo Lançador de Satélite--VLS''), Brazil has developed a series of sounding (research) rockets, named Sonda I, II, III, and IV. The early Sondas were test-launched from Barreira do Inferno Launch Center, near the city of Natal in ...

Communications Satellite
A communications satellite is an artificial satellite that relays and amplifies radio telecommunication signals via a transponder; it creates a communication channel between a source transmitter and a receiver at different locations on Earth. Communications satellites are used for television, telephone, radio, internet, and military applications. Many communications satellites are in geostationary orbit above the equator, so that the satellite appears stationary at the same point in the sky; therefore the satellite dish antennas of ground stations can be aimed permanently at that spot and do not have to move to track the satellite. Others form satellite constellations in low Earth orbit, where antennas on the ground have to follow the position of the satellites and switch between satellites frequently. The high frequency radio waves used for telecommunications links travel by line of sight and so are obstructed by the curve of the Earth. The purpose of communications sate ...

Geostationary Orbit
A geostationary orbit, also referred to as a geosynchronous equatorial orbit''Geostationary orbit'' and ''Geosynchronous (equatorial) orbit'' are used somewhat interchangeably in sources. (GEO), is a circular geosynchronous orbit in altitude above Earth's equator ( in radius from Earth's center) and following the direction of Earth's rotation. An object in such an orbit has an orbital period equal to Earth's rotational period, one sidereal day, and so to ground observers it appears motionless, in a fixed position in the sky. The concept of a geostationary orbit was popularised by the science fiction writer Arthur C. Clarke in the 1940s as a way to revolutionise telecommunications, and the first satellite to be placed in this kind of orbit was launched in 1963. Communications satellites are often placed in a geostationary orbit so that Earth-based satellite antennas do not have to rotate to track them but can be pointed permanently at the position in the sky where the sat ...

Remote Sensing
Remote sensing is the acquisition of information about an object or phenomenon without making physical contact with the object, in contrast to in situ or on-site observation. The term is applied especially to acquiring information about Earth and other planets. Remote sensing is used in numerous fields, including geography, land surveying and most Earth science disciplines (e.g. hydrology, ecology, meteorology, oceanography, glaciology, geology); it also has military, intelligence, commercial, economic, planning, and humanitarian applications, among others. In current usage, the term ''remote sensing'' generally refers to the use of satellite- or aircraft-based sensor technologies to detect and classify objects on Earth. It includes the surface and the atmosphere and oceans, based on propagated signals (e.g. electromagnetic radiation). It may be split into "active" remote sensing (when a signal is emitted by a satellite or aircraft to the object and its reflection detected by ...

Weather Satellite
A weather satellite or meteorological satellite is a type of Earth observation satellite that is primarily used to monitor the weather and climate of the Earth. Satellites can be polar orbiting (covering the entire Earth asynchronously), or geostationary (hovering over the same spot on the equator). While primarily used to detect the development and movement of storm systems and other cloud patterns, meteorological satellites can also detect other phenomena such as city lights, fires, effects of pollution, auroras, sand and dust storms, snow cover, ice mapping, boundaries of ocean currents, and energy flows. Other types of environmental information are collected using weather satellites. Weather satellite images helped in monitoring the volcanic ash cloud from Mount St. Helens and activity from other volcanoes such as Mount Etna. Smoke from fires in the western United States such as Colorado and Utah have also been monitored. El Niño and its effects on weather are monitored ...

Earth Observation Satellite
An Earth observation satellite or Earth remote sensing satellite is a satellite used or designed for Earth observation (EO) from orbit, including spy satellites and similar ones intended for non-military uses such as environmental monitoring, meteorology, cartography and others. The most common type are Earth imaging satellites, that take satellite images, analogous to aerial photographs; some EO satellites may perform remote sensing without forming pictures, such as in GNSS radio occultation. The first occurrence of satellite remote sensing can be dated to the launch of the first artificial satellite, Sputnik 1, by the Soviet Union on October 4, 1957. Sputnik 1 sent back radio signals, which scientists used to study the ionosphere. The United States Army Ballistic Missile Agency launched the first American satellite, Explorer 1, for NASA’s Jet Propulsion Laboratory on January 31, 1958. The information sent back from its radiation detector led to the discovery of the Earth's ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Telecommunication
Telecommunication is the transmission of information by various types of technologies over wire, radio, optical, or other electromagnetic systems. It has its origin in the desire of humans for communication over a distance greater than that feasible with the human voice, but with a similar scale of expediency; thus, slow systems (such as postal mail) are excluded from the field. The transmission media in telecommunication have evolved through numerous stages of technology, from beacons and other visual signals (such as smoke signals, semaphore telegraphs, signal flags, and optical heliographs), to electrical cable and electromagnetic radiation, including light. Such transmission paths are often divided into communication channels, which afford the advantages of multiplexing multiple concurrent communication sessions. ''Telecommunication'' is often used in its plural form. Other examples of pre-modern long-distance communication included audio messages, such as coded drumb ...

Meteorology
Meteorology is a branch of the atmospheric sciences (which include atmospheric chemistry and physics) with a major focus on weather forecasting. The study of meteorology dates back millennia, though significant progress in meteorology did not begin until the 18th century. The 19th century saw modest progress in the field after weather observation networks were formed across broad regions. Prior attempts at prediction of weather depended on historical data. It was not until after the elucidation of the laws of physics, and more particularly in the latter half of the 20th century the development of the computer (allowing for the automated solution of a great many modelling equations) that significant breakthroughs in weather forecasting were achieved. An important branch of weather forecasting is marine weather forecasting as it relates to maritime and coastal safety, in which weather effects also include atmospheric interactions with large bodies of water.
