Abstract	We propose to observe the cluster of galaxies A 665 in order to perform spati-ally resolved spectroscopy with both the RGS and EPIC cameras. A 665 is an idealtarget for this since it has a FWHM of only 1.8 arcmin, allowing a high spectralresolution with the RGS and also an almost complete coverage of the inner partof the cluster within the cross-dispersion width of the detector. In particularwe will study the temperature and abundance distribution within the centralregion using the RGS and in the outer region using the EPIC cameras. The combi-nation of the X-ray properties with already available measurements of theSunyaev-Zeldovich effect will also allow to determine the Hubble constant.

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.
