Un caffè che manda in orbita, e non in senso metaforico: a bordo della Stazione spaziale internazionale (ISS) potrebbe presto fare il suo esordio anche il vero espresso italiano.
La sfida ai limiti delle leggi della fisica è stata raccolta da Argotec, azienda ingegneristica specializzata in sistemi aerospaziali e nell'alimentazione degli astronauti, e da Lavazza, storico marchio del caffè made in Italy. Le due aziende hanno lavorato al primo sistema a capsule in grado di funzionare in orbita, che è stato battezzato 'ISSpresso', dalla sigla della ISS.
In questi giorni una squadra di giovani ingegneri sta mettendo a punto il sistema, sottoponendolo agli ultimi test per rispondere ai rigidi requisiti della Nasa. "La macchina deve resistere alle forti sollecitazioni in fase di lancio - spiegano - operando in condizioni di microgravità e di fluidodinamica completamente diverse da quelle sulla Terra".
