No. 9 Rosetta rides with its comet

While 2014 was the year the Rosetta spacecraft celebrated making it into orbit around a comet, 2015 was the year it got down to some serious hard work. Its comet, with the tongue-twisting name 67P/Churyumov–Gerasimenko, made its closest approach (186 million kilometres) to the Sun, a period known as perihelion when the comet would be expected to be at its most active. Rosetta was there to witness this.


Philae’s descent to comet 67P

Recently released images compiled into a movie show the descent of the European Space Agency’s Philae lander to its first touchdown site, Agilkia, on Comet 67P/Churyumov–Gerasimenko on 12 November 2014. The image sequence starts just over two miles from the comet, and the final image is from just 9 metres above the landing site.
