This is illustrated well in 'Ambition', a short sci-fi film that screened on 24 October 2014 during the British Film Institute’s celebration of Sci-Fi: Days of Fear and Wonder, at the Southbank, London. A collaboration between the European Space Agency and Platige Image, 'Ambition' also features a cameo of Europe's the recently successful cometary mission Rosetta. You can catch updates on this singular mission to comet 67P Churyumov-Gerasimenko (I kid you not, that is its name!) here.
Enjoy and stay curious!
