| Description | We propose to measure the Solar Wind Charge Exchange (SWCX) X-ray emission from the upstream (relative to the solar wind) portion of Earth.s magnetosheath. This is the direction in which the magnetosheath has its highest density of neutral particles, highest solar wind density, and thus its brightest SWCX emission. Although the emissivity, the rate at which X-rays are produced as a function of the neutral and ion densities, can be predicted theoretically, there are sizeable uncertainties which can be reduced only by direct measurement. These measurements can then be used to calculate the amount of SWCX emission due to neutrals in the heliosphere, more tightly constraining the existence of the Local Hot Bubble, and more closely constraining the amount of Galactic halo emission above 0.5 keV. |

| 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. |
