Visual Monitoring Camera
The Visual Monitoring Camera (VMC), also known as the Video Monitoring Camera and Mars Webcam, is a small camera mounted on ''Mars Express'' spacecraft. It is operated by the Mars Express Flight Control Team at ESOC in Darmstadt, Germany. Originally, VMC was a technical camera to monitor the separation of the Beagle 2 lander, but after a few years, it was repurposed into Mars Webcam, streaming its data to the web and even being used for science. Starting in 2007, the VMC was used for the Mars Webcam project, where it takes global views of Mars at a high cadence and they are posted online. The VMC is a camera-on-chip design, using the IRIS-1 system. Originally used as engineering monitoring camera for the ''Beagle 2'' lander, it has a wide 40° field of view and limited imaging controls and it has no focus mechanism. In 2016, it was used for professional science in addition to its roles as a technical monitoring camera and public outreach. History The camera was included on the ...

University Of The Basque Country
The University of the Basque Country ( eu, Euskal Herriko Unibertsitatea, ''EHU''; es, Universidad del País Vasco, ''UPV''; UPV/EHU) is a Spanish public university of the Basque Autonomous Community. Heir of the University of Bilbao, initially it was made up of the Faculty of Economic and Business Sciences of Sarriko (1955), Medicine (1968) and Sciences (1968). Following the General Law of Education (1970), the Nautical School (1784), the School of Business Studies of Bilbao (1818) and the Technical Schools of Engineers (1897) joined in, until it grew into the complex of thirty centers that compose it presently. It has campuses over the three provinces of the autonomous community: Biscay Campus (in Leioa, Bilbao, Portugalete and Barakaldo), Gipuzkoa Campus (in San Sebastián and Eibar), and Álava Campus in Vitoria-Gasteiz. It stands out as the main research institution in the Basque Country, carrying out 90% of the basic research carried out in that territory and benefitin ...

JunoCam
JunoCam (or JCM) is the visible-light camera/telescope onboard NASA's ''Juno'' spacecraft currently orbiting Jupiter. The camera is operated by the JunoCam Digital Electronics Assembly (JDEA). Both the camera and JDEA were built by Malin Space Science Systems. JunoCam takes a swath of imaging as the spacecraft rotates; the camera is fixed to the spacecraft, so as it rotates, it gets one sweep of observation. It has a field of view of 58 degrees with four filters (3 for visible light). Planned goals and outcome Originally, due to telecommunications constraints, ''Juno'' was expected to only be able to return about 40 megabytes of camera data during each 11-day orbital period (the orbital period was later modified). The downlink average data rate of around 325 bits per second will limit the number of images that are captured and transmitted during each orbit to somewhere between 10 and 100 depending on the compression level used. This is comparable to the previous ''Galileo'' m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Field Of View
The field of view (FoV) is the extent of the observable world that is seen at any given moment. In the case of optical instruments or sensors it is a solid angle through which a detector is sensitive to electromagnetic radiation. Humans and animals In the context of human and primate vision, the term "field of view" is typically only used in the sense of a restriction to what is visible by external apparatus, like when wearing spectacles or virtual reality goggles. Note that eye movements are allowed in the definition but do not change the field of view when understood this way. If the analogy of the eye's retina working as a sensor is drawn upon, the corresponding concept in human (and much of animal vision) is the visual field. It is defined as "the number of degrees of visual angle during stable fixation of the eyes".Strasburger, Hans; Pöppel, Ernst (2002). Visual Field. In G. Adelman & B.H.

Black And White
Black-and-white (B&W or B/W) images combine black and white in a continuous spectrum, producing a range of shades of grey. Media The history of various visual media began with black and white, and as technology improved, altered to color. However, there are exceptions to this rule, including black-and-white fine art photography, as well as many film motion pictures and art film(s). Photography Contemporary use Since the late 1960s, few mainstream films have been shot in black-and-white. The reasons are frequently commercial, as it is difficult to sell a film for television broadcasting if the film is not in color. 1961 was the last year in which the majority of Hollywood films were released in black and white. Computing In computing terminology, ''black-and-white'' is sometimes used to refer to a binary image consisting solely of pure black pixels and pure white ones; what would normally be called a black-and-white image, that is, an image containing shades of ...

CMOS
Complementary metal–oxide–semiconductor (CMOS, pronounced "sea-moss", ) is a type of metal–oxide–semiconductor field-effect transistor (MOSFET) fabrication process that uses complementary and symmetrical pairs of p-type and n-type MOSFETs for logic functions. CMOS technology is used for constructing integrated circuit (IC) chips, including microprocessors, microcontrollers, memory chips (including CMOS BIOS), and other digital logic circuits. CMOS technology is also used for analog circuits such as image sensors (CMOS sensors), data converters, RF circuits ( RF CMOS), and highly integrated transceivers for many types of communication. The CMOS process was originally conceived by Frank Wanlass at Fairchild Semiconductor and presented by Wanlass and Chih-Tang Sah at the International Solid-State Circuits Conference in 1963. Wanlass later filed US patent 3,356,858 for CMOS circuitry and it was granted in 1967. commercialized the technology with the trademark ...

The Planetary Society
The Planetary Society is an American internationally-active non-governmental nonprofit organization. It is involved in research, public outreach, and political space advocacy for engineering projects related to astronomy, planetary science, and space exploration. It was founded in 1980 by Carl Sagan, Bruce Murray, and Louis Friedman, and has about 60,000 members from more than 100 countries around the world. The Society is dedicated to the exploration of the Solar System, the search for near-Earth objects, and the search for extraterrestrial life. The society's mission is stated as: "Empowering the world’s citizens to advance space science and exploration." The Planetary Society is a strong advocate for space funding and missions of exploration within NASA. They lobby Congress and engage their membership in the United States to write and call their representatives in support of NASA funding. In addition to public outreach, The Planetary Society has sponsored solar sail ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Beagle 2
The ''Beagle 2'' is an inoperative British Mars lander that was transported by the European Space Agency's 2003 ''Mars Express'' mission. It was intended to conduct an astrobiology mission that would have looked for evidence of past life on Mars. The spacecraft was successfully deployed from the ''Mars Express'' on 19 December 2003 and was scheduled to land on the surface of Mars on 25 December. ESA, however, received no communication from the lander at its expected landing time on Mars, and declared the mission lost in February 2004 after numerous attempts to contact the spacecraft were made. The ''Beagle 2'' fate remained a mystery until January 2015, when it was located on the surface of Mars in a series of images from NASA's '' Mars Reconnaissance Orbiter'' HiRISE camera. The images showed it landed safely but two of its four solar panels failed to deploy, blocking the spacecraft's communications antenna. The ''Beagle 2'' is named after , the ship that took the naturalist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
