ISRO
The Indian Space Research Organisation (ISRO ) is India's national space agency, headquartered in Bengaluru, Karnataka. It serves as the principal research and development arm of the Department of Space (DoS), overseen by the Prime Minister of India, with the Chairman of ISRO also serving as the chief executive of the DoS. It is primarily responsible for space-based operations, space exploration, international space cooperation and the development of related technologies. The agency maintains a constellation of imaging, communications and remote sensing satellites. It operates the GAGAN and IRNSS satellite navigation systems. It has sent three missions to the Moon and one mission to Mars. Formerly known as the Indian National Committee for Space Research (INCOSPAR), ISRO was set up in 1962 by the Government of India on the recommendation of scientist Vikram Sarabhai. It was renamed as ISRO in 1969 and was subsumed into the Department of Atomic Energy (DAE). The establi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

PSLV-C40
PSLV-C40 was the 42nd mission of the Indian Polar Satellite Launch Vehicle (PSLV) program in the XL configuration. PSLV-C40 successfully carried and deployed 31 satellites in Sun-synchronous orbits. Overview Two Surrey Satellite Technology satellites were launched, the 100 kg Carbonite-2 Earth Observation technology demonstrator and the 168 kg Telesat LEO Phase 1 communications satellite. Four SpaceBEE sub-CubeSats were launched to test "2-way satellite communications and data relay", probably for the Silicon Valley company Swarm Technologies. However, the U.S. Federal Communications Commission (FCC) had denied regulatory approval for Swarm Technologies 10 cm × 10 cm × 2.8 cm BEE satellites as they were too small to be reliably tracked by the United States Space Surveillance Network, so may become an impact hazard to other satellites. If confirmed, the FCC may take regulatory action over these satellites. Launched satellites * Astranis DemoSat-2 * ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Satish Dhawan Space Centre
Satish Dhawan Space Centre – SDSC (formerly Sriharikota Range – SHAR) is the primary spaceport of the Indian Space Research Organisation (ISRO), located in Sriharikota, Tirupati district, Andhra Pradesh. The spaceport is located on an island off the east coast of India, surrounded by Pulicat Lake and the Bay of Bengal. The distance of Sriharikota from Chennai is . The Centre currently has three functioning launch pads used for launching sounding rockets, polar satellites and geosynchronous satellites. India's Lunar exploration probes Chandrayaan-1, Chandrayaan-2, Chandrayaan-3, Mars Orbiter Mission, solar research mission Aditya-L1 and space observatory XPoSat were also launched from SDSC. Originally called Sriharikota Range (SHAR), the centre was renamed on 5 September 2002 as a tribute to ISRO's former chairman Satish Dhawan with retaining its original acronym and is referred as SDSC-SHAR. History Sriharikota island was chosen in 1969 for a satellite launchi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orbital Decay
Orbital decay is a gradual decrease of the distance between two orbiting bodies at their closest approach (the periapsis) over many orbital periods. These orbiting bodies can be a planet and its satellite, a star and any object orbiting it, or components of any binary system. If left unchecked, the decay eventually results in termination of the orbit when the smaller object strikes the surface of the primary; or for objects where the primary has an atmosphere, the smaller object burns, explodes, or otherwise breaks up in the larger object's atmosphere; or for objects where the primary is a star, ends with incineration by the star's radiation (such as for comets). Collisions of stellar-mass objects are usually accompanied by effects such as gamma-ray bursts and detectable gravitational waves. Orbital decay is caused by one or more mechanisms which absorb energy from the orbital motion, such as fluid friction, gravitational anomalies, or electromagnetic effects. For bodies ...

Geocentric Orbit
A geocentric orbit, Earth-centered orbit, or Earth orbit involves any object orbiting Earth, such as the Moon or artificial satellites. In 1997, NASA estimated there were approximately 2,465 artificial satellite payloads orbiting Earth and 6,216 pieces of space debris as tracked by the Goddard Space Flight Center. More than 16,291 objects previously launched have undergone orbital decay and entered Earth's atmosphere. A spacecraft enters orbit when its centripetal acceleration due to gravity is less than or equal to the centrifugal acceleration due to the horizontal component of its velocity. For a low Earth orbit, this velocity is about ; by contrast, the fastest crewed airplane speed ever achieved (excluding speeds achieved by deorbiting spacecraft) was in 1967 by the North American X-15. The energy required to reach Earth orbital velocity at an altitude of is about 36 MJ/kg, which is six times the energy needed merely to climb to the corresponding altitude. Spa ...

Sun-synchronous Orbit
A Sun-synchronous orbit (SSO), also called a heliosynchronous orbit, is a nearly polar orbit around a planet, in which the satellite passes over any given point of the planet's surface at the same local mean solar time. More technically, it is an orbit arranged so that it Precession, precesses through one complete revolution each year, so it always maintains the same relationship with the Sun. Applications A Sun-synchronous orbit is useful for imaging satellite, imaging, reconnaissance satellite, reconnaissance, and weather satellites, because every time that the satellite is overhead, the surface illumination angle on the planet underneath it is nearly the same. This consistent lighting is a useful characteristic for satellites that image the Earth's surface in visible or infrared wavelengths, such as weather and spy satellites, and for other remote-sensing satellites, such as those carrying ocean and atmospheric remote-sensing instruments that require sunlight.

Infrared
Infrared (IR; sometimes called infrared light) is electromagnetic radiation (EMR) with wavelengths longer than that of visible light but shorter than microwaves. The infrared spectral band begins with the waves that are just longer than those of red light (the longest waves in the visible spectrum), so IR is invisible to the human eye. IR is generally (according to ISO, CIE) understood to include wavelengths from around to . IR is commonly divided between longer-wavelength thermal IR, emitted from terrestrial sources, and shorter-wavelength IR or near-IR, part of the solar spectrum. Longer IR wavelengths (30–100 μm) are sometimes included as part of the terahertz radiation band. Almost all black-body radiation from objects near room temperature is in the IR band. As a form of EMR, IR carries energy and momentum, exerts radiation pressure, and has properties corresponding to both those of a wave and of a particle, the photon. It was long known that fires e ...

Cartosat-2F
Cartosat-2F is the eighth satellite in the Cartosat-2 Series. It is an Earth observation satellite launched on the PSLV-C40 mission by the Indian Space Research Organisation (ISRO). History Originally, Cartosat-2E was published as the last Cartosat-2 satellite to be launched, as Cartosat-3 Series spacecraft were scheduled to launch in 2018. Cartosat-2F was first listed on launch schedules as Cartosat-2ER, a name possibly indicating it was originally a replica of Cartosat-2E to be used as a spare. Satellite description Like other satellites in the series, Cartosat-2F was built on an IRS-2 bus. It uses reaction wheels, magnetorquers, and hydrazine-fueled reaction control thrusters for stability. It has a design service life of five years. Cartosat-2F has three main remote sensing instruments, a panchromatic camera called PAN, a four channel visible/near infrared radiometer called HRMX, and a Event Monitoring camera (EvM). * Panchromatic camera (PAN) is capable of takin ...
