This research explores the surface properties of ten Centaurs through their reflective properties in the 0.6-5.3 μm range obtained using the JWST/NIRSpec spectrograph in the framework of two different programs: the JWST GO-1 large program "Discovering the Surface Composition of the trans-Neptunian Objects, Icy Embryos for Planet Formation" (DiSCo

ESPRESSO is the VLT ultra-stable high-resolution spectrograph, developed by institutions from Switzerland, Italy, Portugal, Spain, and ESO, located in the combined Coudé Lab of the VLT at ESO, and is able to operate either using one 8.2m-VLT UT or simultaneously with the four VLT UTs. ESPRESSO started routine operations in October 2018 at ESO, and

In December 2020, the Hayabusa2/JAXA mission returned to Earth ~5.4g of primitive material from the carbonaceous asteroid (162173) Ryugu. Since their return, the samples are stored and analysed in the ISAS (Institute of Space and Astronautical Science) Curation Facility. All the analyses in the Curation Facility are conducted under clean and
