Spectrophotometric properties of the nucleus of comet 67P/Churyumov-Gerasimenko from the OSIRIS instrument onboard the ROSETTA spacecraft
The Rosetta mission of the European Space Agency has been orbiting the comet 67P/Churyumov-Gerasimenko (67P) since August 2014 and is now in its escort phase. A large complement of scientificExpand

Water sorption on martian regolith analogs: Thermodynamics and near-infrared reflectance spectroscopy
Abstract The near-infrared reflectance spectra of the martian surface present strong absorption features attributed to hydration water present in the regolith. In order to characterize theExpand

Two independent and primitive envelopes of the bilobate nucleus of comet 67P
The factors shaping cometary nuclei are still largely unknown, but could be the result of concurrent effects of evolutionary and primordial processes. The peculiar bilobed shape of cometExpand

The morphological diversity of comet 67P/Churyumov-Gerasimenko
Images of comet 67P/Churyumov-Gerasimenko acquired by the OSIRIS (Optical, Spectroscopic and Infrared Remote Imaging System) imaging system onboard the European Space Agency’s Rosetta spacecraft atExpand

Gravitational slopes, geomorphology, and material strengths of the nucleus of comet 67P/Churyumov-Gerasimenko from OSIRIS observations
We study the link between gravitational slopes and the surface morphology on the nucleus of comet 67P/Churyumov- Gerasimenko and provide constraints on the mechanical properties of the cometaryExpand

Laboratory observations and simulations of phase reddening
The visible reflectance spectrum of many Solar System bodies changes with changing viewing geometry for reasons not fully understood. It is often observed to redden (increasing spectral slope) withExpand

Surface changes on comet 67P/Churyumov-Gerasimenko suggest a more active past
Changes to the surface geology of comet 67P/Churyumov-Gerasimenko are driven by seasonal factors. The changing surface of a comet From 2014 to 2016, the Rosetta spacecraft investigated cometExpand
