We propose a 45 ksec observation of Abell S1063 (z=0.3475), the second mostX-ray luminous cluster in the ROSAT-ESO Flux Limited X-ray (REFLEX) galaxycluster survey and maybe one of the most massive clusters known. Chandra dataimply strong centroid variation with the core being clearly offset. The veryhigh luminosity L_44=30 and high temperaure T=11 keV imply that this cluster isboosted by merger effects. If this is true for AS1063 we should see a starktemperature structure perhaps similar to that of the .bullet. clusterRXJ0658-55. It is necessary to produce highly resolved temperature maps tocategorize these clusters and to understand their formation and this is notpossible with the existing Chandra data.

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.
