Pew! Rosetta’s comet stinks!

If it were possible to breath in space, one would smell a pungent aroma of rotten eggs, ammonia, vinegary sulphur dioxide and toxic hydrogen cyanide coming from comet 67P/Churyumov–Gerasimenko, according to sensors on the Rosetta mission.


Mars versus the comet

A flotilla of spacecraft orbiting Mars will be turning their instruments in two directions – one towards Comet Siding Spring, and the other towards Mars itself, to find out what happens when a planetary atmosphere brushes against the fuzzy atmosphere of a comet.

Rosetta captures a ‘selfie’ with comet 67P/Churyumov–Gerasimenko

The camera on Rosetta’s Philae lander has snapped a ‘selfie’ with comet 67P/Churyumov–Gerasimenko in the distance about 16 km away. The image was taken on 7 October and also captures the side of the Rosetta spacecraft and one of the 14 metre-long solar wings. Two images with different exposure times were combined to bring out the faint details in this very high contrast situation. The comet’s active ‘neck’ region is clearly visible, with streams of dust and gas extending away from the surface. Image: ESA/Rosetta/Philae/CIVA.
