Philae (Rosetta Lander): Experiment status after commissioning

Rosenbauer, H.; Biele, J.; Bibring, J. P. +2 more

Being successfully launched on March 2, 2004, ESA's cornerstone mission "ROSETTA" (originally planned to be launched in January 2003 to comet Wirtanen) is en route. It will also bring the 100 kg Lander "Philae" with a scientific payload of 26.7 kg to the surface of comet 67P/Churyumov-Gerasimenko. After a first scientific sequence in 2014 it will …

67P/Churyumov Gerasimenko nucleus model: Portrayal of the Rosetta target

Coradini, A.; De Sanctis, M. C.; Capria, M. T.

Rosetta is a cornerstone ESA mission dedicated to the detailed study of a comet nucleus before and after the onset of activity. Comet 67P/Churyumov-Gerasimenko is the new Rosetta target. At the moment, little is known about this comet, but the successful design of the ROSETTA mission requires some preliminary knowledge of the comet's physical para…

Multidimensional physicochemical models of the near-nucleus coma: Present achievements and requested future developments

Crifo, J. -F.

The published multidimensional physicochemical simulations of the near-nucleus coma (hereafter "NNC") are reviewed. The goals of these simulations are to understand the physical origin of the observed NNC structure(s), and to relate the latter to properties of the nucleus - an inference which is often done on the basis of subjective impressions on…

Modelling the large particle environment of comet 67P/Churyumov Gerasimenko

Agarwal, J.; Grün, E.; Müller, M. +1 more

A method is presented to simulate images of a cometary dust trail in consistency with observed gas and dust production rates. It is also applicable to dust tails including neckline and antitail phenomena. Our main objective is to analyse the amount of mm-sized and larger particles within a given image. These are interesting to us because their emi…

Physical parameters of the plasma tail of Rosetta target comet 67P/Churyumov-Gerasimenko

Churyumov, K. I.

On the basis of photometric processing of the two large scale photographic images of comet 67P obtained in Nizhny Arkhyz with the help of the 6-BTA reflector of SAO of RAS and using the diffusion model of L. Shulman and H. Nazarchuk some physical parameters of magnetic field of the comet plasma tail (coefficients of diffusion and induction of magn…
