- Abstract
XMM-Newton is an ESA telescope in orbit since Dec 1999. It could be the first ESA cornerstone mission in the “ESA Horizon 2000” to extend its lifetime beyond its 10 years of expected operations. The Flight Control Team (FCT) with support from other ESOC departments (e.g. Flight Dynamics, Software Support and Ground Segment Support), is evaluating the status of the entire mission system. Special attention is given to subsystems health, estimation of consumables, orbit evolution, units degradation, hardware and software availability and redundancies. Ground Systems and H/W obsolescence on ground is another key factor in a successful mission continuation. Operations extension, therefore, not only involve the Spacecraft, but also all the ground related systems. In this paper, particular emphasis will be given to the platform status, reporting performance data of major subsystems and how the in-flight data differ from design prediction. Same attention will be given also to the information of Orbital and Ground related aspects. Industry has often remarked that feedback from flight missions is not provided so they lack data to help in further improvement of their products. In this occasion those data will be forwarded to industry to be taken into account in the design of other long duration mission.
