While the Rosetta space probe’s Philae lander prepares to land on the comet 67P/Churyumov-Gerasimenko on November 12, the analyzes at a distance go on. The comet is about 450 million kilometers (about 280 million miles) from the Sun and its activity is increasing due to the sublimation of the ice, which becomes steam. The ROSINA (Rosetta Orbiter Spectrometer for Ion and Neutral Analysis) instrument has already analyzed some emissions finding that the comet really stinks.
