The Optical, Spectroscopic, and Infrared Remote Imaging System OSIRIS is the scientific
camera system onboard the Rosetta spacecraft (Figure 1). The advanced high performance …

Images from the OSIRIS scientific imaging system onboard Rosetta show that the nucleus of
67P/Churyumov-Gerasimenko consists of two lobes connected by a short neck. The nucleus …

On the basis of previous ground-based and fly-by information, we knew that Titan's atmosphere
was mainly nitrogen, with some methane, but its temperature and pressure profiles were …

Images of comet 67P/Churyumov-Gerasimenko acquired by the OSIRIS (Optical, Spectroscopic
and Infrared Remote Imaging System) imaging system onboard the European Space …

The Rosetta spacecraft reached Comet 67P/Churyumov-Gerasimenko (hereafter 67P/CG)
in August 2014 at an heliocentric distance of 3.6 au and was then put in orbit around its …

Context. The Rosetta mission of the European Space Agency has been orbiting the comet
67P/Churyumov-Gerasimenko (67P) since August 2014 and is now in its escort phase. A …

Context. The complex shape of comet 67P and its oblique rotation axis cause pronounced
seasonal effects. Irradiation and hence activity vary strongly.Aims. We investigate the …

We analyzed more than 200 OSIRIS NAC images with a pixel scale of 0.9−2.4 m/pixel of
comet 67P/Churyumov-Gerasimenko (67P) that have been acquired from onboard the Rosetta …

Pits have been observed on many cometary nuclei mapped by spacecraft 1 , 2 , 3 , 4 . It has
been argued that cometary pits are a signature of endogenic activity, rather than impact …

The factors shaping cometary nuclei are still largely unknown, but could be the result of
concurrent effects of evolutionary 1 , 2 and primordial processes 3 , 4 . The peculiar bilobed …
