Between 2007 and 2023 our XMM-Newton monitoring of SN1987A yielded EPIC and RGSspectra of unprecedented quality. The fluxes and broadening of the numerousemission lines provide information on the evolution of the X-ray emitting plasmaand its dynamics. The soft X-ray light curve has displayed a steady flux declinefrom 2014 decreasing 21% of its peak value by 2023. To further monitor theevolution of the X-ray flux and to follow the expected turnover we propose tocontinue our monitoring.This will allow us to further study the time evolutionof the shock conditions and abundance profiles. At high energies EPIC-pn canmonitor the hard band continuum and help to clarify the extremely low observedFe abundance by following the evolution of the detected Fe-K line [truncated!
