TECHNOBARA ricordano questo evento...
Rosetta è stata una missione spaziale sviluppata dall'Agenzia Spaziale Europea e lanciata nel 2004 e finita nel 2016. L'obiettivo della missione fu, dopo un cambio dovuto alla posticipazione del lancio, lo studio della cometa 67P/Churyumov-Gerasimenko. La missione era formata da due elementi: la sonda vera e propria Rosetta e il lander Philae, atterrato il 12 novembre 2014 sulla superficie della cometa 67P/Churyumov Gerasimenko. La missione si è conclusa il 30 settembre 2016, con lo schianto programmato dell'orbiter sulla cometa e disattivazione del segnale.

Rosetta was a space probe built by the European Space Agency launched on 2 March 2004. Along with Philae, its lander module, Rosetta performed a detailed study of comet 67P/Churyumov–Gerasimenko (67P).[ During its journey to the comet, the spacecraft flew by Mars and the asteroids 21 Lutetia and 2867 Šteins.
On 6 August 2014, the spacecraft reached the comet and performed a series of manoeuvres to be captured in its orbit. On 12 November, its lander module Philae performed the first successful landing on a comet, though its battery power ran out two days later.Communications with Philae were briefly restored in June and July 2015, but due to diminishing solar power, Rosetta's communications module with the lander was turned off on 27 July 2016. On 30 September 2016, the Rosetta spacecraft ended its mission by landing on the comet at the Ma'at region.
The probe is named after the Rosetta Stone, a stele of Egyptian origin featuring a decree in three scripts. The lander is named after the Philae obelisk, which bears a bilingual Greek and Egyptian hieroglyphic inscription.

European Space Agency officials have used their Rosetta spacecraft to listen to a sound emitted by Comet 67P/Churyumov-Gerasimenko. The comet song capture by Rosetta is produced by "oscillations in the magnetic field in the comet's environment," ESA officials said in a statement.
