Rosetta : dans quelques heures, la sonde spatiale déposera Philae sur la surface de la comète 67 P/Churyumov-Gerasimenko, une première mondiale
La descente de Philae devrait prendre sept heures et se fera depuis une altitude de 12,5 km dans la passivité la plus totale : les ingénieurs de l’ESA ne pourront pas modifier sa trajectoire. Un vrai challenge.
