Description | We propose to utilize the very favorable observing conditions of Mars for XMM in Oct 2018 for detailed studies of Solar Wind Charge Exchange (SWCX) in its exosphere, accompanied by simultaneous in-situ measurements of the solar wind with Mars Express and MAVEN. XMM, the by far best X-ray satellite for this kind of study, has already detected 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 possibility of remote global imaging of planetary exospheres and their spatial and temporal variability. As the observation will take place close to solar minimum, any interference with scattered solar X-rays will be minimized. |

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. |
