SABIA-Mar
The SABIA-Mar (Spanish: ), originally called SAC-E by CONAE, is a dual satellite joint Earth observation mission. The mission objective is to study the oceanic biosphere, its changes over time, and how it is affected by and reacts to human activity. It will focus on the monitoring of ocean surfaces, especially studying the ocean ecosystem, the carbon cycle, and marine habitats, as well as ocean mapping. This collaboration between the Argentine (CONAE) and the Brazilian ( AEB) space agencies was originally supposed to make two identical spacecraft with Argentina supplying the payload and Brazil the satellite bus. The satellites, SABIA-Mar A and SABIA-Mar B, were supposed to fly in 2017 and 2018, and operate until 2021. By 2016, CONAE announced that a new agreement had been reached, where Argentina would build SABIA-Mar 1, and Brazil would build SABIA-Mar 2. The Argentine satellite, SABIA-Mar 1, is supposed to fly in 2024. SABIA-Mar 1 SABIA-Mar 1 will be designed and built by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brazilian Space Agency
The Brazilian Space Agency ( pt, Agência Espacial Brasileira; AEB) is the civilian authority in Brazil responsible for the country's space program. It operates a spaceport at Alcântara, and a rocket launch site at Barreira do Inferno. It is the largest and most prominent space agency in Latin America. The Brazilian Space Agency is the institutional successor of Brazil's space program, which had been managed by the Brazilian military until its transfer to civilian control on 10 February 1994. It suffered a major setback in 2003, when a rocket explosion killed 21 technicians. Brazil successfully launched its first rocket into space, the VSB-30, on 23 October 2004 from the Alcântara Launch Center; several other successful launches have followed. Brazil was briefly a partner in the International Space Station, and in 2006, AEB astronaut Marcos Pontes became the first Brazilian and the first native Portuguese-speaker to go into space, when he arrived at the ISS for a week.

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Comisión Nacional De Actividades Espaciales
Comisión Nacional de Actividades Espaciales (CONAE; in English, National Space Activities Commission) is the civilian agency of the government of Argentina in charge of the national space programme. History Sociedad Argentina Interplanetaria During the 1940s, Teófilo Tabanera organized a group of foreign and Argentine specialists as the Sociedad Argentina Interplanetaria, SAI (Argentine Interplanetary Society). Tabanera's efforts ensured that Argentina was the first Latin American nation to create a spaceflight organisation and in 1952 was one of the founding members of the International Astronautical Federation. Argentine Aldo Cocca was a pioneer in space law and helped originate the idea of space being the common heritage of humankind, later enshrined in United Nations treaties of the 1960s. Comisión Nacional de Investigaciones Espaciales In 1960, Tabanera was named head of the newly created ''Comisión Nacional de Investigaciones Espaciales'' CNIE (National Commi ...

Earth Observation Satellites Of Brazil
Earth is the third planet from the Sun and the only astronomical object known to harbor life. While large volumes of water can be found throughout the Solar System, only Earth sustains liquid surface water. About 71% of Earth's surface is made up of the ocean, dwarfing Earth's polar ice, lakes, and rivers. The remaining 29% of Earth's surface is land, consisting of continents and islands. Earth's surface layer is formed of several slowly moving tectonic plates, which interact to produce mountain ranges, volcanoes, and earthquakes. Earth's liquid outer core generates the magnetic field that shapes the magnetosphere of the Earth, deflecting destructive solar winds. The atmosphere of the Earth consists mostly of nitrogen and oxygen. Greenhouse gases in the atmosphere like carbon dioxide (CO2) trap a part of the energy from the Sun close to the surface. Water vapor is widely present in the atmosphere and forms clouds that cover most of the planet. More solar energy is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Satellites Of Argentina
A satellite or artificial satellite is an object intentionally placed into orbit in outer space. 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 is small CubeSats. Similar satellites can work together as a group, forming constellations. Because of the high launch cost to space, satellites are designed to be as lightweight and robust as possible. Most communication satellites are radio relay stations in orbit and carry dozens of transponders, each with a bandwidth of tens of megahertz. Satellites are placed from the surface to orbit by launch vehicles, high enough to avoid orbital decay by the atmosphere. Satellites can then change or maintain the orbit by propulsio ...

Sensor
A sensor is a device that produces an output signal for the purpose of sensing a physical phenomenon. In the broadest definition, a sensor is a device, module, machine, or subsystem that detects events or changes in its environment and sends the information to other electronics, frequently a computer processor. Sensors are always used with other electronics. Sensors are used in everyday objects such as touch-sensitive elevator buttons ( tactile sensor) and lamps which dim or brighten by touching the base, and in innumerable applications of which most people are never aware. With advances in micromachinery and easy-to-use microcontroller platforms, the uses of sensors have expanded beyond the traditional fields of temperature, pressure and flow measurement, for example into MARG sensors. Analog sensors such as potentiometers and force-sensing resistors are still widely used. Their applications include manufacturing and machinery, airplanes and aerospace, cars, medicine, r ...

Charge-coupled Device
A charge-coupled device (CCD) is an integrated circuit containing an array of linked, or coupled, capacitors. Under the control of an external circuit, each capacitor can transfer its electric charge to a neighboring capacitor. CCD sensors are a major technology used in digital imaging. In a CCD image sensor, pixels are represented by p-doped metal–oxide–semiconductor (MOS) capacitors. These MOS capacitors, the basic building blocks of a CCD, are biased above the threshold for inversion when image acquisition begins, allowing the conversion of incoming photons into electron charges at the semiconductor-oxide interface; the CCD is then used to read out these charges. Although CCDs are not the only technology to allow for light detection, CCD image sensors are widely used in professional, medical, and scientific applications where high-quality image data are required. In applications with less exacting quality demands, such as consumer and professional digital camera ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Multispectral Image
Multispectral imaging captures image data within specific wavelength ranges across the electromagnetic spectrum. The wavelengths may be separated by filters or detected with the use of instruments that are sensitive to particular wavelengths, including light from frequencies beyond the visible light range, i.e. infrared and ultra-violet. It can allow extraction of additional information the human eye fails to capture with its visible receptors for red, green and blue. It was originally developed for military target identification and reconnaissance. Early space-based imaging platforms incorporated multispectral imaging technology to map details of the Earth related to coastal boundaries, vegetation, and landforms. Multispectral imaging has also found use in document and painting analysis. Multispectral imaging measures light in a small number (typically 3 to 15) of spectral bands. Hyperspectral imaging is a special case of spectral imaging where often hundreds of contig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amazônia-1
The Amazônia-1 or SSR-1 (in Portuguese: ''Satélite de Sensoriamento Remoto-1''), is the first Earth observation satellite developed by Brazil, helped by Argentina's INVAP, who provided the main computer, attitude controls and sensors, and the training of Brazilian engineers, and launched at 04:54:00 UTC (10:24:00 IST) on 28 February 2021. Operations will be joint with the China–Brazil Earth Resources Satellite program (CBERS-4) satellite. Background In the early 1990s, the design of SSR (Satélite de Sensoriamento Remoto) satellites, Amazônia-1 precursor, was revised and Instituto Nacional de Pesquisas Espaciais (INPE) technicians proposed replacing the polar orbit by an equatorial orbit, and this proposal was accepted. That made sense at that time as Brazil already had polar orbit coverage with the CBERS satellites. SSR-1 suffered several delays, either by lack of resources, or bid disputes. The effective start only occurred in 2001, when a contract was signed for t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Satellite Bus
A satellite bus (or spacecraft bus) is the main body and structural component of a satellite or spacecraft, in which the payload and all scientific instruments are held. Bus-derived satellites are opposed to specially produced satellites. Bus-derived satellites are usually customized to customer requirements, for example with specialized sensors or transponders, in order to achieve a specific mission. They are commonly used for geosynchronous satellites, particularly communications satellites, but are also used in spacecraft which occupy lower orbits, occasionally including low Earth orbit missions. Examples Some satellite bus examples include: * Boeing DS&S 702 * Lockheed Martin Space Systems A2100 * Alphabus * INVAP ARSAT-3K * Airbus D&S Eurostar * ISRO's I-1K, I-2K, I-3K, I-4K, I-6K, and Indian Mini Satellite bus * NASA Ames MCSB * SSL 1300 * Orbital ATK GEOStar * Mitsubishi Electric DS2000 * Spacecraft bus of the James Webb Space Telescope * SP ...
