GT-We propose to observe two filaments in the shock region of the Vela SupernovaRemnant which we have already observed in the optical and in the X-Ray band(with ROSAT/PSPC). We have found out that there is a strong evidence of shock-ISM inhomogeneities interaction, but the low spatial and spectral resolution ofPSPC data prevented us to study the real nature of the X-ray emission. In particular, our primary goal is to carry on spatially resolved spectral analysison a 1x1 arcmin resolution element of the post-shock region. This will allow usto discriminate clearly between the interaction processes, either evaporative orbow shock or secondary shocks, to derive the metal abundances behind the shock,and to understand the connection between different ISM phases.

Mission Description
The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
