Estimation of surface temperatures on Mercury in preparation of the MERTIS experiment onboard BepiColombo

Hiesinger, Harald; Helbert, Jörn; Bauch, Karin E. +1 more

The Mercury Radiometer and Thermal Infrared Spectrometer (MERTIS) is part of the payload on the joint ESA-JAXA BepiColombo Mission, launched in October 2018. The spectrometer is designed to map surface composition, identify rock-forming minerals, map surface mineralogy, and study surface temperature variations. The surface of Mercury undergoes lar…

Mid-infrared reflectance spectroscopy of synthetic glass analogs for Mercury surface studies

Helbert, Joern; Hiesinger, Harald; Weber, Iris +14 more

We have synthesized and analyzed by mid-infrared reflectance spectroscopy silicate glasses that are representative for the glasses on the surface of Mercury. The glass compositions are based on high-pressure laboratory experiments and the resulting compositions of the glass phase. The spectra are of interest for investigating the surface of Mercur…
