We propose to utilize the unique opportunity provided by the presence of MarsExpress for the first ever combination of remote X-ray observations of solarwind charge exchange (SWCX) emission with simultaneous measurements of the solarwind at Mars. XMM-Newton is by far the best X-ray satellite for this kind ofstudy. In a previous Mars observation, it has already provided the first direct,unambiguous detection of SWCX emission from the exosphere of another planet.This finding has consequences for X-ray astrophysics in general (plasmadiagnostics and soft X-ray background), and is important for planetary evolution(atmospheric outgassing). It opens up a novel possibility of remote globalimaging of planetary exospheres and their spatial and temporal variability.

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.
