| Abstract | We propose to investigate the heavy ion content of the elusive polar solar windby observing the cometary X-ray emission which results from charge exchangebetween solar wind heavy ions and cometary neutrals, thus providing in-situinformation. We will utilize the favorable opportunity that AO-17 will be closeto solar minimum, when the polar wind will have expanded to lower latitudes, andthat one bright comet, 21P/Giacobini-Zinner, will be continuously observable forXMM and close to Earth on its way from +30 deg to -30 deg ecliptic latitude.This observation is perfectly tailored to XMM, as it makes full use of its highsoft X-ray sensitivity, its spectral, temporal, and spatial resolution, its fullfield of view, and of all six (PN, MOS1, MOS2, RGS1, RGS2, OM) of its scientific instruments. |

| 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. |
