| Description | We propose a 30 ks XMM observation of the accreting millisecond pulsar SAX J1808.4--3658, during its next outburst. A measure of its orbital parameters will help to decide whether the system is losing mass at an extraordinary rate or whether some (quasi)-cyclic variation of the orbit is currently ongoing. Understanding how the orbit is evolving will also provide precise orbital ephemeris which are crucial to improve the sensitivity of radio and gamma-ray pulse searches. |

| 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. |
