(Main)Space engineering - Space environment
Space engineering - Space environment
This standard applies to all product types which exist or operate in space and defines the natural environment for all space regimes. It also defines general models and rules for determining the local induced environment.
Project-specific or project-class-specific acceptance criteria, analysis methods or procedures are not defined.
The natural space environment of a given item is that set of environmental conditions defined by the external physical world for the given mission (e.g. atmosphere, meteoroids and energetic particle radiation). The induced space environment is that set of environmental conditions created or modified by the presence or operation of the item and its mission (e.g. contamination, secondary radiations and spacecraft charging). The space environment also contains elements which are induced by the execution of other space activities (e.g. debris and contamination).
This standard may be tailored for the specific characteristic and constrains of a space project in conformance with ECSS-S-ST-00.

Vesoljska tehnika - Okolje v vesolju
Ta standard se uporablja za vse vrste proizvodov, ki obstajajo ali delujejo v vesolju, in določa naravno okolje za vse vesoljske režime. Določa tudi splošne modele in pravila za ugotavljanje lokalnega ustvarjenega okolja. Merila sprejemljivosti, analizne metode ali postopki za posamezen projekt ali posamezen razred projekta niso opredeljeni. Naravno okolje v vesolju določenega predmeta je tisti sklop okoljskih pogojev, ki ga določa zunanji fizični svet za določeno misijo (npr. atmosfera, meteoroidi in sevanje energijskih delcev). Ustvarjeno okolje v vesolju je tisti sklop okoljskih pogojev, ki ga ustvari ali spremeni prisotnost ali delovanje predmeta in njegove misije (npr. onesnaženje, drugotna sevanja in polnjenje vesoljskega plovila). Okolje v vesolju zajema tudi elemente, ki jih ustvari izvajanje drugih vesoljskih dejavnosti (npr. odpadki in onesnaženje). Ta standard se lahko prilagodi posameznim lastnostim in omejitvam vesoljskega projekta v skladu s standardom ECSS-S-ST-00.
