Gli astronauti della Stazione spaziale internazionale (ISS) sono soddisfatti del raccolto del loro orto stellare. Per la prima volta infatti, riferisce la NASA, hanno assaggiato la verdura fresca coltivata in orbita, per l'esattezza un ceppo di lattuga romana.
L’operazione, al di là della gastronomia, rappresenta un passo importante in vista di possibili future missioni umane di lunga durata nello spazio. Le foglie di insalata, lavate con una salviettina igienizzante, sono state condite con olio e aceto. Alcune sono state congelate e saranno riportate sulla Terra per ulteriori analisi.
Un'insalata "spaziale" (EBU)

Come detto, si tratta di lattuga rossa romana ed è la prima verdura interamente coltivata e mangiata nello spazio. A piantarla era stato 33 giorni fa l'astronauta americano Scott Kelly, la cui missione durerà complessivamente un anno, ed è cresciuta all'interno di una piccola serra realizzata dalla società Veggie Orbital Technologies. I prossimi passi saranno quelli di far crescere verdure e ortaggi più complessi, che garantiscono un maggior apporto nutritivo come pomodori e mirtilli. Agli astronauti non resta che augurare buon appetito…
