Description Using four carefully distributed pointings, we propose to observe the soft-Xray spectrum of the diffuse component of the Milky Way bulge through Baade.s window, i.e. nearly through the galactic center, and at two higher-z positions. The foreground will be removed from these observations using a nearby pointing towards a high-extinction region. We hope to use the bulge spectrum to: 1. Determine, with the aid of non-equilibrium modeling, the physical state of the gas at the base of the bulge, and how that state changes with distance from the mid-plane. 2. Calculate the total diffuse soft X-ray emission from the bulge, to compare the Milky Way to the bulge of M101. 3. Determine the spectrum of the foreground emission that may be due to hot gas in the Sco-Cen bubble.

Mission Description The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's 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 Earth's 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.
