This is a coordinated HST+XMM-Newton program to address the conditions thataffect habitability on Earth-like planets around Sun-like stars. Both wavelengthregimes (far-UV with HST, X-rays with XMM) are needed to constrain modelssufficiently to represent realistic conditions. An approved TESS program for ourtargets will provide additional information on surface inhomogeneities (spots)and their sizes and locations so that that can be taken into account as well.The FUV and X-ray fluxes from young stars are erosive of a planet.s atmosphere,particularly for hydrogen, but also for oxygen and nitrogen, both chemicallyimportant elements.

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.
