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 p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

ELA-1
ELA-1, short for Ensemble de Lancement Ariane 1 ( French for Ariane Launch Area 1), now named Ensemble de Lancement Vega (short ELV), is a launch pad at the Centre Spatial Guyanais in French Guiana. It has been used to support launches of the Europa rocket, Ariane 1, Ariane 3, and is currently used to launch Vega rockets. History Europa (BEC) ELA-1, at the time designated Base Équatoriale du CECLES (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 CECLES pad. This was designated Ensemble de Lancement Ariane (ELA). The first Ariane 1 launch occurred on 24 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Earth Observation
Earth observation (EO) is the gathering of information about the physical, chemical, and biological systems of the planet Earth. It can be performed via 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 data". Earth observation is used to monitor and assess the status of and changes in 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 countries and over 100 participating organizations, uses EO in this broader sense. In t ...

Electromagnetic Spectrum
The electromagnetic spectrum is the range of frequencies (the spectrum) of electromagnetic radiation and their respective wavelengths and photon energies. The electromagnetic spectrum covers electromagnetic waves with frequencies ranging from below one hertz to above 1025 hertz, corresponding to wavelengths from thousands of kilometers down to a fraction of the size of an atomic nucleus. This frequency range is divided into separate bands, and the electromagnetic waves within each frequency band are called by different names; beginning at the low frequency (long wavelength) end of the spectrum these are: radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays at the high-frequency (short wavelength) end. The electromagnetic waves in each of these bands have different characteristics, such as how they are produced, how they interact with matter, and their practical applications. There is no known limit for long and short wavelengths. Extreme ultr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 the part of stamp(s). Stamps on the miniature sheet can be in se-tenant position while the same stamps were not se-t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
