Ruag Space si è aggiudicata un contratto per la Stazione Spaziale Internazionale (ISS). La filiale di Nyon, specializzata nello sviluppo di bioreattori spaziali, dovrà sviluppare e dimostrare l'efficacia di un sistema di ricircolo dell'aria, basato su microalghe, un progetto dell'Agenzia Spaziale Europea chiamato BIORAT.
Sistemi di sopravvivenza innovativi vengono sviluppati per la stazione marziana, qui nel suo concetto di base
Se l'uomo vuole andare su Marte, devono essere sviluppate tecnologie per riciclare l'aria, l'acqua e i rifiuti umani in un circuito chiuso. Per quanto riguarda l'aria, le alghe sono particolarmente utili, poiché quasi il 50% della produzione mondiale di ossigeno proviene da queste piante, ha ricordato la società in un comunicato stampa diramato lunedì.
Le alghe sono efficaci nel rigenerare l'aria attraverso la fotosintesi. Sono quindi particolarmente adatte per le cabine spaziali con equipaggio. Ma questo richiede lo sviluppo di fotobioreattori specializzati, in grado di coltivare questi microrganismi in microgravità e a gravità parziale.
