WorldView-4
''WorldView-4'', previously known as ''GeoEye-2'', was a third generation commercial Earth observation satellite launched on 11 November 2016, at 18:30:33 UTC. The spacecraft was operated by DigitalGlobe. With a maximum resolution of , ''WorldView-4'' provided similar imagery as ''WorldView-3'', the highest resolution commercially available at the time of its launch. The spacecraft suffered a failure in one of its control moment gyroscopes in January 2019, and operations were unable to be recovered. It reentered over New Zealand on 30 November 2021. History Work on ''GeoEye-2'' began in October 2007 when commercial imagery company GeoEye selected ITT Corporation to begin work on long lead-time items for the satellite camera system. In March 2010, an initial contract for construction of the spacecraft was awarded to Lockheed Martin Space Systems, which previously built the '' Ikonos'' imaging satellite. At the time, ''GeoEye-2'' was planned for launch in late 2012. The s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

DigitalGlobe
DigitalGlobe is an American commercial vendor of space imagery and geospatial content, and operator of civilian remote sensing spacecraft. The company went public on the New York Stock Exchange on 14 May 2009, selling 14.7 million shares at US$19.00 each to raise US$279 million in capital. On 5 October 2017, Maxar Technologies completed its acquisition of DigitalGlobe. The company's "WorldView" satellites should not be confused with the unrelated WorldView company (a stratospheric balloon operator). Origins WorldView Imaging Corporation was founded in January 1992 in Oakland, California in anticipation of the 1992 Land Remote Sensing Policy Act (enacted in October 1992) which permitted private companies to enter the satellite imaging business. Its founder was Dr Walter Scott, who was joined by co-founder and CEO Doug Gerull in late 1992. In 1993, the company received the first high resolution commercial remote sensing satellite license issued under the 1992 Act. The company ...

Atlas V
Atlas V is an expendable launch system and the fifth major version in the Atlas launch vehicle family. It was originally designed by Lockheed Martin, now being operated by United Launch Alliance (ULA), a joint venture between Lockheed Martin and Boeing. Atlas V is also a major NASA launch vehicle. It is America's longest-serving active rocket. In August 2021, ULA announced that Atlas V would be retired, and all 29 remaining launches had been sold. , 19 launches remain. Each Atlas V launch vehicle consists of two main stages. The first stage is powered by a Russian RD-180 engine manufactured by Energomash and burning kerosene and liquid oxygen. The Centaur upper stage is powered by one or two American RL10 engine(s) manufactured by Aerojet Rocketdyne and burns liquid hydrogen and liquid oxygen. The Star 48 upper stage was used on the '' New Horizons'' mission as a third stage. Strap-on solid rocket boosters (SRBs) are used in most configurations. AJ-60A SRBs were u ...

Canyon Fire (2016)
The Canyon Fire was a wildfire that burned on Vandenberg Space Force Base in Santa Barbara County, California during September 2016. By the time the fire was contained on September 24, it had burned of land. Due to the nature of the activities that take place on the Base, there were a number of unique challenges posed during the fire including the presence of potentially hazardous materials. The fire The fire broke out September 17 and quickly grew to over . Due to the location of the fire, burning in a remote canyon on the southern half of the base, access was difficult for fire crews. On September 18 the fire jumped to over prompting evacuation warnings for homes on San Miguelito Canyon south of Lompoc and east of the base. By mid-afternoon on September 19 the fire had grown to over and with no containment was continuing to burn with a moderate rate of spread. As the fire continued to spread, firefighters were faced with a number of unique challenges. Base officials warned ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lockheed Martin Space Systems
Lockheed Martin Space is one of the four major business divisions of Lockheed Martin. It has its headquarters in Littleton, Colorado, with additional sites in Valley Forge, Pennsylvania; Sunnyvale, California; Santa Cruz, California; Huntsville, Alabama; and elsewhere in the United States and United Kingdom. The division currently employs about 16,000 people, and its most notable products are commercial and military satellites, space probes, missile defense systems, NASA's Orion spacecraft, and the Space Shuttle external tank.

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Launch Vehicle
A launch vehicle or carrier rocket is a rocket designed to carry a payload ( spacecraft or satellites) from the Earth's surface to outer space. Most launch vehicles operate from a launch pads, supported by a launch control center and systems such as vehicle assembly and fueling. Launch vehicles are engineered with advanced aerodynamics and technologies, which contribute to large operating costs. An orbital launch vehicle must lift its payload at least to the boundary of space, approximately and accelerate it to a horizontal velocity of at least . Suborbital vehicles launch their payloads to lower velocity or are launched at elevation angles greater than horizontal. Practical orbital launch vehicles are multistage rockets which use chemical propellants such as solid fuel, liquid hydrogen, kerosene, liquid oxygen, or Hypergolic propellants. Launch vehicles are classified by their orbital payload capacity, ranging from small-, medium-, heavy- to super-heavy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
InSight
Insight is the understanding of a specific cause and effect within a particular context. The term insight can have several related meanings: *a piece of information *the act or result of understanding the inner nature of things or of seeing intuitively (called noesis in Greek) *an introspection *the power of acute observation and deduction, discernment, and perception, called intellection or noesis *An understanding of cause and effect based on the identification of relationships and behaviors within a model, context, or scenario (see artificial intelligence) An insight that manifests itself suddenly, such as understanding how to solve a difficult problem, is sometimes called by the German word '' Aha-Erlebnis''. The term was coined by the German psychologist and theoretical linguist Karl Bühler. It is also known as an epiphany, eureka moment or (for cross word solvers) the penny dropping moment (PDM). Sudden sickening realisations often identify a problem rather than solvin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Service Structure
A service structure is a steel framework or tower that is built on a rocket launch pad to facilitate assembly and servicing. An umbilical tower also usually includes an elevator which allows maintenance and crew access. Immediately before ignition of the rocket's motors, all connections between the tower and the craft are severed, and the bridges over which these connections pass often quickly swing away to prevent damage to the structure or vehicle. Kennedy Space Center During the Space Shuttle program, the structures at the Launch Complex 39 pads contained a two-piece access tower system, the Fixed Service Structure (FSS) and the Rotating Service Structure (RSS). The FSS permitted access to the Shuttle via a retractable arm and a "beanie cap" to capture vented LOX from the external tank. The RSS contained the Payload Changeout Room, which offered "clean" access to the orbiter's payload bay, protection from the elements, and protection in winds up to . The FSS on Pad 39A was c ...
