The international Rosetta mission was launched in 2004 and consists of the orbiter
spacecraft Rosetta and the lander Philae. The aim of the mission is to map the comet …

The Philae lander accomplished the first soft landing and the first scientific experiments of a
human-made spacecraft on the surface of a comet. Planned, expected and unexpected …

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 …

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. We investigate the formation and evolution of comet nuclei and other trans-
Neptunian objects (TNOs) in the solar nebula and primordial disk prior to the giant planet …

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 …

Context. We present an investigation of the surface properties of areas on the nucleus of
comet 67P/Churyumov-Gerasimenko. Aims. We aim to show that transport of material from …

The factors sha** cometary nuclei are still largely unknown, but could be the result of
concurrent effects of evolutionary, and primordial processes,. The peculiar bilobed shape of …

We collect observational evidence that supports the scheme of mass transfer on the nucleus
of comet 67P/Churyumov–Gerasimenko. The obliquity of the rotation axis of 67P causes …

During its 2 yr mission around comet 67P/Churyumov–Gerasimenko, ESA's Rosetta
spacecraft had the unique opportunity to follow closely a comet in the most active part of its …
