Nearby galaxy clusters present a unique opportunity to study the spatialvariation of the physical properties of the ICM and they also provide us withtemplates to test the biases introduced by simplifications assumed in theanalysis of more distant clusters. Perseus stands out as the optimal choice forsuch an analysis, due to its brightenss, proximity, and ubiquitous physicalcharacteristics. We propose 4 short observations that will allow us tocompletely map SN Type enrichment, gas bulk velocities, and other physicalparameters up to virgul0.3-0.4 of its virial radius. This analysis will addressseveral current issues, such as the excess SN Ia pollution in the outer clusterregions and the claimed presence of velocity gradients in the ICM.

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.
