Abstract	Our special vantage point in our Galaxy allows us to study the Galactic warm-hothalo along several sightlines. The combination of absorption and emissionmeasurements provides a powerful tool in this regard. One immediate step forwardwould be to use emission measures close to the sightlines of absorption lines.With the proposed observations we will determine emission measures close to fivesightlines in which we have detected z=0 absorption lines with Chandra. Thiswill break the degeneracy between density and path-length and robustly measurethe extent and mass of the warm-hot halo, placing strongest constraints yet onthe fraction of missing baryons in the warm-hot plasma.

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.
