|Title||Simultaneous study of SWCX at Mars near solar maximum with XMM and Mars Express|
|Author||Dr Konrad Dennerl|
|Description||We propose to utilize the exceptionally favorable observing conditions of Mars for XMM in June 2014 for detailed studies of solar wind charge exchange (SWCX) induced X-ray emission in its exosphere, accompanied by simultaneous in-situ measurements of the solar wind with Mars Express. XMM has already provided the first direct, unambiguous detection of SWCX emission from the Martian exosphere. This finding has consequences for X-ray astrophysics in general (soft X-ray background), is important for our understanding of planetary evolution (atmospheric outgassing), and opens up a novel method for remote global imaging of planetary exospheres and their spatial and temporal variability. There will be no similarly favorable opportunity before 2023.|

|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.
