| Description | Although contamination monitoring was introduced and vigorously pursued after the RGS and MOS were cooled in 2002 November, it is important to establish a long-term contamination monitor. The star zeta Puppis is an ideal target because of the exceptional strength of its NVI and NVII lines at about 25 and 30A respectively. So far, XMM has not been able to detect any variability in this star above the few percent level. It is visible for 2 months every 6 months and for this long-term programme, I propose a longer observation time than used during the immediate post-cooling period, prefering instead the 60ks used for the PV phase. |

| 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. |
