TL;DR: The VIRTIS instrument on board the Rosetta spacecraft has provided evidence of carbon-bearing compounds on the nucleus of the comet 67P/Churyumov-Gerasimenko, and no ice-rich patches are observed, indicating a generally dehydrated nature for the surface currently illuminated by the Sun.

TL;DR: Lutetia is likely a remnant of the primordial planetesimal population, unaltered by differentiation processes and composed of chondritic materials of enstatitic or carbonaceous origin, dominated by iron-poor minerals that have not suffered aqueous alteration.

TL;DR: The stratigraphy observed on comet 67P/Churyumov–Gerasimenko is the result of evolutionary processes affecting the uppermost metres of the nucleus and does not necessarily require a global layering to have occurred at the time of the comet’s formation.

TL;DR: The European Space Agency's Rosetta spacecraft is the first Solar System mission to include instrumentation capable of measuring planetary thermal fluxes at both near-IR (VIRTIS) and sub-millimeter-mm (smm-mm, MIRO) wavelengths as discussed by the authors.

TL;DR: In this article, the authors presented a global map of the night side TEC variations, which correlates well with the magnetic field model derived from Mars Global Surveyor (MGS) Magnetometer/Electron Reflectometer (MAG/ER) data.
