SPENVIS
The Space Environment Information System (SPENVIS) is an ESA operational software developed and maintained at Belgian Institute for Space Aeronomy since 1996. It provides a web-based interface for assessing the Space environment Space environment is a branch of astronautics, aerospace engineering and space physics that seeks to understand and address conditions existing in space that affect the design and operation of spacecraft.

The system is used by an international user community for various purposes, e.g. mission analysis and planning, educational support, and running models for scientific applications. SPENVIS also includes extensive background information on the space environment and the environment models. References External linksSPENVIShome page European Space Agency {{Space-stub ...

Space Environment
Space environment is a branch of astronautics, aerospace engineering and space physics that seeks to understand and address conditions existing in space that affect the design and operation of spacecraft. A related subject, space weather, deals with dynamic processes in the solar-terrestrial system that can give rise to effects on spacecraft, but that can also affect the atmosphere, ionosphere and geomagnetic field, giving rise to several other kinds of effects on human technologies. Effects on spacecraft can arise from radiation, space debris and meteoroid impact, upper atmospheric drag and spacecraft electrostatic charging. Radiation in space usually comes from three main sources: # The Van Allen radiation belts # Solar proton events and solar energetic particles; and # Galactic cosmic rays. For long-duration missions, the high doses of radiation can damage electronic components and solar cells. A major concern is also radiation-induced "single-event effects" such as si ...

Belgian Institute For Space Aeronomy
The Royal Belgian Institute for Space Aeronomy (BIRA-IASB) ( nl, Koninklijk Belgisch Instituut voor Ruimte-Aeronomie - BIRA, french: Institut royal d'aéronomie spatiale de Belgique - IASB) is a Belgian federal scientific research institute. Created in 1964, its main tasks are research and public service in space aeronomy, which is the physics and chemistry of the atmosphere of the Earth and other planets, and of outer space. The scientists rely on ground-based, balloon-, air- or space-borne instruments and computer models. History On 25 November 1964 the Aeronomical Service is separated from the Royal Meteorological Institute (RMI) and lives on as a scientific institution of the state with the name: Belgian Institute for Space Aeronomy (BIRA-IASB). In 2014, BIRA-IASB celebrates its 50th anniversary and gains its royal statute. On this occasion, the Institute gathere50 important events in its history The institute has as main competence, tasks of public service and research in th ...

Web Application
A web application (or web app) is application software that is accessed using a web browser. Web applications are delivered on the World Wide Web to users with an active network connection. History In earlier computing models like client-server, the processing load for the application was shared between code on the server and code installed on each client locally. In other words, an application had its own pre-compiled client program which served as its user interface and had to be separately installed on each user's personal computer. An upgrade to the server-side code of the application would typically also require an upgrade to the client-side code installed on each user workstation, adding to the technical support, support cost and decreasing productivity. In addition, both the client and server components of the application were usually tightly bound to a particular computer architecture and operating system and porting them to others was often prohibitively expensive for ...
