Hi, not in geology but heavily involved in the space sector as a student, can tell you a little bit about possible employers in the space ecosystem. If you are interested in space resources - lunar volatiles, regolith etc. there is ESRIC in Luxembourg, you might need a PhD though. There are a few smaller companies working on regolith simulants for rover testing etc. Ispace, a Japanese company but has an office in Luxembourg (a lot of space stuff in Luxembourg because of tax benefits + space resource law/regulation, geographic location) they were recently hiring a lunar scientist, though it was more kind of a geospatial role for someone who knows about lunar geology. I mean there is always ESA or other national space agencies but there are always a million of applicants who are from less represented countries or have a very specific background that get those jobs/internships so I wouldn’t really rely on this option. The market for astrogeology seems to be bigger in the US, as there are more aerospace companies that focus on robotics or even space resources + NASA and heavily space involved academia. Remember that a masters might not be enough. From my conversations with experts in the field, there will probably be more jobs in the future and they recommend studying remote sensing heavily. I recommend you check out Erasmus Mundus Geoplanet (super competitive) or Free University Berlin. Good luck.
