INSAT-1D
INSAT-1D was 4th and the concluding multipurpose geostationary satellite of the INSAT-1 (first-generation seven-year responsibility for the operation of the INSAT space segment. But the success of this launch meant a lot to India - a country that was setting up its national computer networks. Relying on a lot of communication circuits, microwave, coaxial, and fibre-optic telecommunication links throughout the country causes a huge problem; and thus the Indian Space Research Organisation (ISRO) planned at the start of the INSAT-1 series to always have at least two satellites in space to meet the increasing demand of telecommunication links for India's civilian community. INSAT-1A and INSAT-1C had already faced immature death and their plans had suffered a serious setback. Another satellite INSAT-1B, launched in 1983, exceeded its planned seven-year working life. Launch INSAT 1D was built by Ford Aerospace (now Loral Inc) for the Indian National Satellite System. Initially, the lau ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ...

Indian Space Research Organisation
The Indian Space Research Organisation (ISRO; ) is the national space agency of India, headquartered in Bengaluru. It operates under the Department of Space (DOS) which is directly overseen by the Prime Minister of India, while the Chairman of ISRO acts as the executive of DOS as well. ISRO is India's primary agency for performing tasks related to space-based applications, space exploration and the development of related technologies. It is one of six government space agencies in the world which possess full launch capabilities, deploy cryogenic engines, launch extraterrestrial missions and operate large fleets of artificial satellites. The Indian National Committee for Space Research (INCOSPAR) was established by Jawaharlal Nehru under the Department of Atomic Energy (DAE) in 1962, on the urging of scientist Vikram Sarabhai, recognising the need in space research. INCOSPAR grew and became ISRO in 1969, within DAE. In 1972, the government of India set up a Space Commissi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solar Sail
Solar sails (also known as light sails and photon sails) are a method of spacecraft propulsion using radiation pressure exerted by sunlight on large mirrors. A number of spaceflight missions to test solar propulsion and navigation have been proposed since the 1980s. The first spacecraft to make use of the technology was IKAROS, launched in 2010. A useful analogy to solar sailing may be a sailing boat; the light exerting a force on the mirrors is akin to a sail being blown by the wind. High-energy laser beams could be used as an alternative light source to exert much greater force than would be possible using sunlight, a concept known as beam sailing. Solar sail craft offer the possibility of low-cost operations combined with long operating lifetimes. Since they have few moving parts and use no propellant, they can potentially be used numerous times for delivery of payloads. Solar sails use a phenomenon that has a proven, measured effect on astrodynamics. Solar pressure affec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Delta II
Delta II was an expendable launch system, originally designed and built by McDonnell Douglas. Delta II was part of the Delta rocket family and entered service in 1989. Delta II vehicles included the Delta 6000, and the two later Delta 7000 variants ("Light" and "Heavy"). The rocket flew its final mission ICESat-2 on 15 September 2018, earning the launch vehicle a streak of 100 successful missions in a row, with the last failure being GPS IIR-1 in 1997. History In the early 1980s, all United States expendable launch vehicles were planned to be phased out in favor of the Space Shuttle, which would be responsible for all government and commercial launches. Production of Delta, Atlas-Centaur, and Titan 34D had ended. The ''Challenger'' disaster of 1986 and the subsequent halt of Shuttle operations changed this policy, and President Ronald Reagan announced in December 1986 that the Space Shuttle would no longer launch commercial payloads, and NASA would seek to purchase launches ...

Cape Canaveral Space Force Station
Cape Canaveral Space Force Station (CCSFS) is an installation of the United States Space Force's Space Launch Delta 45, located on Cape Canaveral in Brevard County, Florida. Headquartered at the nearby Patrick Space Force Base, the station is the primary launch site for the Space Force's Eastern RangeCAST 1999, p. 1-12. with three launch pads currently active (Space Launch Complexes 37B, 40, and 41). The facility is south-southeast of NASA's Kennedy Space Center on adjacent Merritt Island, with the two linked by bridges and causeways. The Cape Canaveral Space Force Station Skid Strip provides a runway close to the launch complexes for military airlift aircraft delivering heavy and outsized payloads to the Cape. A number of American space exploration pioneers were launched from CCSFS, including the first U.S. Earth satellite (1958), first U.S. astronaut (1961), first U.S. astronaut in orbit (1962), first two-man U.S. spacecraft (1965), first U.S. unmanned lunar land ...

Cape Canaveral Space Launch Complex 17 -b
Space Launch Complex 17 (SLC-17), previously designated Launch Complex 17 (LC-17), was a launch site at Cape Canaveral Air Force Station (CCAFS), Florida used for Thor and Delta launch vehicles launches between 1958 and 2011. It was built in 1956 for use with the PGM-17 Thor missile, the first operational ballistic missile in the arsenal of the United States. More recently the launch complex has been used for vehicles in the Delta launch vehicle family, derived from the Thor missile, to launch probes to the Moon and planets, solar observatories and weather satellites. SLC-17 features two expendable launch vehicle (ELV) launch pads, 17A and 17B. The pads were operated by the 45th Space Wing and have supported more than 300 Department of Defense, NASA and commercial missile and rocket launches. Following the last military launch, in August 2009, SLC-17A was withdrawn from use, and LC-17B was transferred to NASA (SLC-17B) for two remaining launches. Pad 17A supported i ...

1989 Loma Prieta Earthquake
The 1989 Loma Prieta earthquake occurred on California's Central Coast on October 17 at local time. The shock was centered in The Forest of Nisene Marks State Park in Santa Cruz County, approximately northeast of Santa Cruz on a section of the San Andreas Fault System and was named for the nearby Loma Prieta Peak in the Santa Cruz Mountains. With an magnitude of 6.9 and a maximum Modified Mercalli intensity of IX (''Violent''), the shock was responsible for 63 deaths and 3,757 injuries. The Loma Prieta segment of the San Andreas Fault System had been relatively inactive since the 1906 San Francisco earthquake (to the degree that it was designated a seismic gap) until two moderate foreshocks occurred in June 1988 and again in August 1989. Damage was heavy in Santa Cruz County and less so to the south in Monterey County, but effects extended well to the north into the San Francisco Bay Area, both on the San Francisco Peninsula and across the bay in Oakland.
