La NASA ha annunciato venerdì che in luglio del 2020 un mini elicottero decollerà da Cape Canaveral insieme a un mezzo di esplorazione al suolo in direzione di Marte, meta che dovrebbe raggiungere nel febbraio del 2021.
L’aeromobile battezzato "Mars Helicopter" pesa circa 1,8 chilogrammi e la sua fusoliera ha le dimensioni di una palla da baseball. Le sue eliche possono compiere 3'000 giri al minuto, 10 volte di più di quanto accade sulla terra. Inoltre il velivolo è dotato di celle solari e di un meccanismo di riscaldamento che permettono di caricarne le batterie.
L’agenzia spaziale degli Stati Uniti, con questa sperimentazione, intende dimostrare la sostenibilità e l’utilità di questi apparecchi per studi geologici e verificare l'abitabilità del pianeta rosso.
