| Abstract | To use clusters as sensitive probes to study the emergence of cosmic structureand to test cosmological models, we need a better knowledge of the scalingrelations of cluster mass and observable properties. With this goal a LargeProgram was approved in AO3 to study a representative sample of 34 clusters indetail. The observations are now completed. While we obtained very good resultsfor a large fraction of the clusters, a substantial fraction of the data arerendered unusable by high background events as demonstrated below. To achieveour observational goals, it is critical that the complete sample be observed andthe clusters with the poorest data, 9 clusters, be reobserved. In addition, notethat multi-wavelength observations of the entire sample have begun. |

| 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. |
