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 physical properties of cometary nuclei observed today relate to their complex history
and help to constrain their formation and evolution. In this article, we review some of the …

The near-Earth asteroid 162173 Ryugu, the target of the Hayabusa2 sample-return mission,
is thought to be a primitive carbonaceous object. We report reflectance spectra of Ryugu's …

The Philae lander, part of the Rosetta mission to investigate comet 67P/Churyumov-
Gerasimenko, was delivered to the cometary surface in November 2014. Here we report the …

The processes that led to the formation of the planetary bodies in the Solar system are still
not fully understood. Using the results obtained with the comprehensive suite of instruments …

The ESA Rosetta spacecraft followed comet 67P at a close distance for more than 2 yr. In
addition, it deployed the lander Philae on to the surface of the comet. The (surface) …

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 …

ABSTRACT The Rosetta probe, orbiting Jupiter-family comet 67P/Churyumov–
Gerasimenko, has been detecting individual dust particles of mass larger than 10− 10 kg by …

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 …
