Outgassing-induced effects in the rotational state of comet 67P/Churyumov—Gerasimenko during the Rosetta mission
Samarasinha, Nalin H.; Lamy, Philippe; Jorda, Laurent +1 more
The new target of the Rosetta mission is comet 67P/Churyumov-Gerasimenko (hereafter 67P/C-G). In order to support the planning of the mission, in particular the strategy during the mapping and landing phases, we have performed numerical simulations of the rotational evolution of a comet in the orbit of 67P/C-G. In these simulations, the currently …
The ground calibration setup of OMEGA and VIRTIS experiments: description and performances
Langevin, Yves; Gondet, Brigitte; Bonello, Guillaume +4 more
Hyperspectral imagery is an essential technique for remote sensing of surfaces and atmospheres of planetary objects. However, given the instrumental complexity of coupling imaging and spectroscopy, in particular in the infrared, an in-depth ground calibration is mandatory to enable an unbiased and optimized data reduction. This paper presents the …
