satelliitissa

Satelliitissa is the inessive singular form of the Finnish noun satelliitti, meaning "in a satellite" or "inside a satellite." In Finnish, the inessive case (-ssa/-ssä) marks location within something, so satelliitissa denotes being inside a satellite—physically within its internal space or structure. The term is used mainly in technical and scientific texts dealing with space hardware, spacecraft interiors, and satellite systems, but may also appear in journalism or fiction describing space missions.

Usage and examples: In technical writing, satelliitissa is used to refer to locations, components, or processes inside a satellite. For example: "Tutkimuslennon aikana mitatut arvot tallennettiin satelliitissa olevaan muistivarastoon." "Satelliitissa olevat järjestelmät vaativat erityistä luotettavuutta." "Säteilyn vaikutukset satelliitissa toimivien laitteiden käyttöikään ovat tutkimuksen kohteena." These illustrate describing interiors, equipment, and effects occurring within a satellite.

Etymology and notes: The noun satelliitti is a loanword from the international term satellite, likely via Swedish satellit or English. The -ssa ending is the standard Finnish inessive marker, used to express "inside the satellite." Other grammatical forms are formed by regular inflection of the noun. Satelliitissa is thus a regular morphological form, not a separate concept.
