Abstract	We propose two 50-ksec observations of the transient millisecond X-ray pulsarSAX J1808.4-3658 (J1808) in quiescence. The previous (36 ksec XMM, MOS only)observation of J1808s X-ray spectrum did not show a clear blackbody-likecomponent from the neutron star (NS) surface. J1808s known mass transfer rateand low photon cooling rate require rapid neutrino cooling. This is the mostrestrictive current constraint upon the structure of NS interiors, and thus onthe behavior of matter at high densities. We propose a substantial improvementof this constraint, capable of ruling out a pion condensate as the mechanism forrapid neutrino cooling. Our secondary objective is to measure or constrain anyvariability in the quiescent X-ray luminosity and spectrum of J1808.

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.
