Su Marte ci sono le condizioni per la crescita delle patate. Questa affermazione è stata fatta da ricercatori del Centro internazionale per la patata sulla base di un esperimento effettuato tra metà febbraio e l’inizio di marzo a Lima, in Perù.
Il tubero, proveniente da una selezione creata usando un centinaio di varietà, è stato coltivato sotto una speciale cupola che ha riprodotto la situazione climatica all’aperto sul pianeta rosso.
La terra utilizzata è stata estratta dal deserto della Pampa de la Joya, dove il suolo è simile a quello marziano. Si è fatto ricorso a fertilizzanti. La patata è originaria delle Ande; in Europa è giunta alla metà del 1500.
