Esivalmisteluna

Esivalmisteluna is a Finnish neologism that has appeared in online discussions and speculative fiction to describe a preparatory phase related to the Moon. The word combines esi- (before), valmistelu (preparation) and luna (moon), reflecting a Finnish tendency to form process terms by compounding roots. There is no standardized definition in astronomy, space policy, or academic Finnish, and the term is not part of official terminology.

In informal use, esivalmisteluna denotes the period of planning, simulations, risk assessment, and coordination that precedes a lunar operation such as a landing, rover deployment, or observational campaign. In this sense it can be understood as the conceptual equivalent of “pre-mission preparation” or “prelude to a lunar event.” Its attested usage is sparse and largely confined to community-driven glossaries, discussion forums about space exploration, and some works of science fiction in Finnish. Because of its informal status, interpretations vary, and the term can be used metaphorically to describe preparatory work in projects beyond lunar contexts. Some writers emphasize its speculative or rhetorical function rather than a precise technical category.
