| Abstract | JWST will be able to observe the atmospheres of rocky planets transiting nearbyM dwarfs. A few such planets are already known (around GJ1132, Proxima Cen, andTrappist-1) and TESS is predicted to find many more. Our MUSCLES Treasury Survey(Cycles 19+22) used Hubble/COS+STIS UV observations with contemporaneous X-rayand ground-based data to construct complete SEDs for 11 low-mass exoplanethosts. Here, we propose to expand the MUSCLES project to: (a) new M dwarfexoplanet hosts with varying properties; (b) reference M dwarfs below 0.3 solarmasses that may be used as proxies for M dwarf planet hosts; and (c) morerapidly rotating stars of GJ1132s mass to probe XUV evolution over Gyrtimescales. We propose to gather the first panchromatic SEDs of rocky planet hosts GJ1132 and Trappist-1. |

| 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. |
