The Nucleus of comet 67P/Churyumov–Gerasimenko – Part I: The global view – nucleus mass, mass-loss, porosity, and implications
Martin Pätzold,Thomas Andert,Matthias Hahn,Jean-Pierre Barriot,Sami W. Asmar,Bernd Häusler,Michael K. Bird,Silvia Tellmann,Janusz Oschlisniok,Kerstin Peter +9 more
TL;DR: The radio science experiment RSI on-board Rosetta determined the mass of the nucleus of comet 67P/Churyumov-Gerasimenko at the start of the prime mission from 2014 August to November (GM = 666.2 ± 0.2 m3 s−2 or 9982 ± 3 × 1012 kg).

TL;DR: The radio signals are affected by the medium through which the signals propagate (atmospheres, ionospheres, interplanetary medium, solar corona), by the gravitational influence of the planet on the spacecraft and finally by the performance of various systems involved both on the satellite and on ground.

Rosetta CONSERT Data as a Testbed for In Situ Navigation of Space Probes and Radiosciences in Orbit/Escort Phases for Small Bodies of the Solar System
Mao Ye,Fei Li,Jianguo Yan,Alain Herique,Wlodek Kofman,Yves Rogez,Thomas Andert,Xi Guo,Jean-Pierre Barriot +8 more
TL;DR: In this article, the authors investigate the use of CONSERT ranging data acquired in direct visibility between the lander Philae and the Rosetta orbiter, in the frame of the ESA space mission to comet 67P/Churyumov-Gerasimenko, as a proxy of autonomous navigation and orbitography science capability.
