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.

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 ...

2014 In Spaceflight
In 2014, the maiden flight of the Angara A5, Antares 120 and Antares 130 took place. A total of 92 orbital launches were attempted in 2014, of which 88 were successful, two were partially successful and two were failures. The year also saw seven EVAs by ISS astronauts. The majority of the year's orbital launches were conducted by Russia, the United States and China, with 34, 23 and 16 launches respectively. Overview An Ariane 5 ES launched the ''Georges Lemaître'' Automated Transfer Vehicle, the last one of the series, which also marked 60 successfully completed Ariane 5 launches in a row. On 22 August 2014, Arianespace launched the first two Full Operational Capability Galileo satellites for the European satellite navigation system. A number of significant events in planetary exploration occurred in 2014, including the entry of the Rosetta spacecraft into orbit around the comet 67P/Churyumov–Gerasimenko in August 2014 and the deployment of the Philae lander to its su ...

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] |
Panchromatic
Panchromatic emulsion is a type of black-and-white photographic emulsion that is sensitive to all wavelengths of visible light. Description A panchromatic emulsion renders a realistic reproduction of a scene as it appears to the human eye, although with no colors. Almost all modern photographic film is panchromatic. Some older types of film were orthochromatic and were not sensitive to certain wavelengths of light. As naturally prepared, a silver halide photographic emulsion is much more sensitive to blue and UV light than to green and red wavelengths. The German chemist Hermann W. Vogel found out how to extend the sensitivity into the green, and later the orange, by adding sensitising dyes to the emulsion. By the addition of erythrosine the emulsion could be made orthochromatic while some cyanine derivatives confer sensitivity to the whole visible spectrum making it panchromatic. However, his technique was not extended to achieve a fully panchromatic film until the early 190 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Point Rosee
Point Rosee (French: ''Pointe Rosée''), previously known as Stormy Point, is a headland near Codroy at the southwest end of the island of Newfoundland, on the Atlantic coast of Canada. In 2014, archaeologist Sarah Parcak, using near-infrared satellite images discovered a possible Norse site at Point Rosee, Newfoundland. If confirmed, it would have been the second known Viking or Norse site in Newfoundland and the second Norse site in North America outside of Greenland. Point Rosee was excavated in 2015 and 2016, by a team of researchers directed by Parcak and co-directed by her husband Gregory "Greg" Mumford. In their November 8, 2017, report that was submitted to the Provincial Archaeology Office in St. John's, Newfoundland, Parcak and Mumford wrote that they "found no evidence whatsoever for either a Norse presence or human activity at Point Rosee prior to the historic period" and that "None of the team members, including the Norse specialists, deemed this area as having an ...

Vikings
Vikings ; non, víkingr is the modern name given to seafaring people originally from Scandinavia (present-day Denmark, Norway and Sweden), who from the late 8th to the late 11th centuries raided, pirated, traded and settled throughout parts of Europe.Roesdahl, pp. 9–22. They also voyaged as far as the Mediterranean, North Africa, Volga Bulgaria, the Middle East, and North America. In some of the countries they raided and settled in, this period is popularly known as the Viking Age, and the term "Viking" also commonly includes the inhabitants of the Scandinavian homelands as a collective whole. The Vikings had a profound impact on the early medieval history of Scandinavia, the British Isles, France, Estonia, and Kievan Rus'. Expert sailors and navigators aboard their characteristic longships, Vikings established Norse settlements and governments in the Viking activity in the British Isles, British Isles, the Faroe Islands, Settlement of Iceland, Icela ...
