TL;DR: Measurements of the interior of Comet 67P/Churyumov-Gerasimenko by Radiowave Transmission (CONSERT) suggest the upper part of the “head” of 67P is fairly homogeneous on a spatial scale of tens of meters, and the dust component may be comparable to that of carbonaceous chondrites.

TL;DR: In this paper, the authors review the requirements and model dielectric properties of asteroids to outline a possible instrument suite, and highlight the capabilities of radar instrumentation to achieve these observations.

TL;DR: In this article, the authors used the propagation of the Comet Nucleus Sounding Experiment by Radiowave Transmission (CONSERT) signal throughout the small lobe of the 67P/CG nucleus to deduce the real part of the permittivity, at a value of 1.27 ± 0.05.
Journal ArticleDOI
Homogeneity of 67P/Churyumov-Gerasimenko as seen by CONSERT: implication on composition and formation
TL;DR: In this paper, the sensitivity of measurements to local variations in density, dust-to-ice ratio, and composition was analyzed using permittivity modeling of mixtures, and the maximum detectable heterogeneity size and contrast in terms of composition and porosity of the nucleus was analyzed.
PHILAE Localization from CONSERT / ROSETTA Measurement.
TL;DR: In this paper, the authors presented the measurements and the estimate of the final position of the Philae lander in November 2014, using the CONSERT data enabled an initial estimate to be made of Philae's location based on signals propagated through the 67P/CG nucleus, which was then refined through three sets of measurements carried out during periods of direct visibility between Rosetta and Philae during the first science sequence (FSS).
