A complete and extensive mineralogical survey of extraterrestrial bodies is actually possible only by means of remote sensing spectrometers, measuring the planetary surfaces in a spectral range that goes from the visible to the far infrared. The list of instruments still active today, observing the most interesting planets and bodies in our solar system is far too long to list them in this abstract. The important message is that all of them are sending to Earth a huge amount of data that needs to be correctly analysed, to infer the mineralogical composition of the observed regions on different targets. This requires laboratory data of relevant analogue materials under relevant conditions measured on a wide spectral range. At the Planetary Emissivity Laboratory (PEL) of DLR in Berlin two separate instruments, a Bruker IFS 88 and a Bruker Vertex 80V are operated in parallel and independently to measure reflectance and emissivity of planetary analogue materials to cover the 0.4 to 100 µm spectral range. The older IFS 88 is used to measure under room pressure and for emissivity measurements from low to moderate temperatures (up to 180° C), while the new Vertex 80V can be evacuated (below 1 mbar) and used to measure emissivity of moderate to very hot surfaces, reaching temperatures typical of the daily Mercury (beyond 500° C). The laboratory set-up and the already obtained results will be described, together with details about the online-archival and the standardized structure of the existing dataset.
