PROBA-V
PROBA-V, or PROBA-Vegetation (the ''V'' standing for ''vegetation'' and not the Roman numeral for ''5''), is a satellite in the European Space Agency's PROBA series. It was launched in 2013 with a predicted usable lifetime between 2.5 and 5 years. Satellite ''PROBA-V'' is a small satellite, assuring the succession of the Vegetation instruments on board the French SPOT-4 and SPOT-5 Earth observation missions. PROBA-V was initiated by the Space and Aeronautics department of the Belgian Science Policy Office. It is built by QinetiQ Space N.V. and operated by ESA and uses a PROBA platform. PROBA-V will support applications such as land use, worldwide vegetation classification, crop monitoring, famine prediction, food security, disaster monitoring and biosphere studies. The mission was originally conceived as a "gap filler" between the SPOT-5 end-of-life (foreseen mid-2014) and the launch of the constellation of the Sentinel-3A and -3B satellites. Due to delays of the Sentinel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vega (rocket)
Vega (, , ) was a European expendable small-lift launch vehicle developed by Avio and operated by Arianespace for the European Space Agency (ESA) and the Italian Space Agency (ASI). Designed to carry payloads between into low Earth and polar orbits, Vega served primarily scientific and Earth observation missions. Development of Vega began in 1998, with its maiden flight launched from the Guiana Space Centre on 13February 2012. Over the next decade, it became the eighth most launched small-lift launch vehicle history, though it struggled to compete in the commercial launch market. After initial success, two in-flight failures and rising competition from SpaceX's rideshare programs, which offered lower prices, relegated Vega to primarily serving European government agencies willing to pay more to support independent space access. The rocket took its name from Vega, the brightest star in the constellation Lyra. It featured a single-body design without strap-on boosters, con ...

PROBA-3
PROBA-3 is a dual-probe technological demonstration mission by the European Space Agency devoted to high-precision formation flying to achieve scientific coronagraphy. It is part of the series of PROBA satellites that are being used to validate new spacecraft technologies and concepts while also carrying scientific instruments. It lifted off aboard ISRO's PSLV-XL rocket from Satish Dhawan Space Center in Sriharikota, India. The project is managed by Damian Galano. Mission concept PROBA-3 consists of two independent, three-axis-stabilized spacecraft: the Coronagraph Spacecraft (CSC) and the Occulter Spacecraft (OSC). The spacecraft will fly close to each other on a highly elliptical orbit around the Earth, with an apogee at 60,500 km altitude. ESA said that by flying in tight formation about 150 metres apart, the Occulter will precisely cast its shadow onto the Coronagraph’s telescope, blocking the Sun’s direct light. This will allow the Coronagraph to image the faint so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
OIP Sensor Systems
OIP Sensor Systems is an Israeli-owned Belgian defence and space company. History The company was founded in Ghent in as (Precision Optics and Instruments), as an effort of Belgium to develop its own optical industry for its Belgian Armed Forces, army. From its foundation until the 1950s, OIP developed military lenses and objectives, medical and scientific microscopes, as well as cameras and photocopy machines for the industry. From the 1960s on, it was one of the first European companies to enter the emerging electro-optical market, with innovations such as one of the first heads-up display for the Lockheed F-104 Starfighter and fire control systems for the Leopard 1 battle tanks in Belgium, Canada and Australia together with SABCA.

ELA-1
ELV () is a launch complex at the Guiana Space Centre in French Guiana supporting launches of the Vega and Vega C rockets. It was first built in November 1971 and was previously used to support launches of the Europa, Ariane 1 and Ariane 3 rockets. History Europa (BEC) ELA-1, at the time designated BEC () was constructed as an equatorial launch site for the Europa-II rocket which was being built as part of the ELDO programme. The first launch occurred on 5 November 1971. This was the only flight of the Europa-II, which ended in failure due to a guidance problem. The launch site was mothballed, and later demolished. Ariane (ELA) When the Ariane 1 programme was started, to replace the failed ELDO programme, a new launch site was built on the site of the former BEC, re-designated as ELA (). The first Ariane 1 launch occurred on 24 December 1979. ELA was also used by Ariane 2 and Ariane 3 rockets, which first flew on 31 May 1986 and 4 August 1984 respectively. ELA wa ...

Earth Observation
Earth observation (EO) is the gathering of information about the physical, chemical, and biosphere, biological systems of the planet Earth. It can be performed via remote sensing, remote-sensing technologies (Earth observation satellites) or through direct-contact sensors in ground-based or airborne platforms (such as weather stations and weather balloons, for example). According to the Group on Earth Observations (GEO), the concept encompasses both "space-based or remotely-sensed data, as well as ground-based or In situ#Earth and atmospheric sciences, in situ data". Earth observation is used to monitor and assess the status of and changes in natural environment, natural and built environments. Terminology In Europe, ''Earth observation'' has often been used to refer to satellite-based remote sensing, but the term is also used to refer to any form of observations of the Earth system, including in situ and airborne observations, for example. The GEO, which has over 100 member coun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

List Of European Space Agency Programs And Missions
A list is a set of discrete items of information collected and set forth in some format for utility, entertainment, or other purposes. A list may be memorialized in any number of ways, including existing only in the mind of the list-maker, but lists are frequently written down on paper, or maintained electronically. Lists are "most frequently a tool", and "one does not ''read'' but only ''uses'' a list: one looks up the relevant information in it, but usually does not need to deal with it as a whole". Lucie Doležalová,The Potential and Limitations of Studying Lists, in Lucie Doležalová, ed., ''The Charm of a List: From the Sumerians to Computerised Data Processing'' (2009). Purpose It has been observed that, with a few exceptions, "the scholarship on lists remains fragmented". David Wallechinsky, a co-author of '' The Book of Lists'', described the attraction of lists as being "because we live in an era of overstimulation, especially in terms of information, and lists help ...

Souvenir Sheet
A souvenir sheet or miniature sheet is a postage stamp or a small group of postage stamps still attached to the sheet on which they were printed. They may be either regular issues that just happen to be printed in small groups (typical of many early stamps), or special issues often commemorating some event, such as a national anniversary, philatelic exhibition, or government program. The number of stamps ranges from one to about 25; larger sheets of stamps are simply called "sheets" with no qualifier. The stamps on the sheet may be perforated in the usual way, or imperforate. The margins or selvage of the sheet may have additional printing, ranging from a simple statement of the occasion being commemorated, up to a full picture of which the stamp(s) are just a small part. The margins of the sheet may have ornamental designs, price, emblems and logo(s) which are not part of stamp(s). Stamps on the miniature sheet can be in se-tenant position while the same stamps were not se-tenan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
