| Abstract: | The future X-ray missions for high resolution spectroscopy are briefly reviewed. ASTRO-H, planned for launch in 2014, will introduce microcalorimeters for the first time and reveal dynamical motions of hot gas in extended objects. High resolution spectroscopy will also be used for the search of missing baryons with oxygen lines in the local universe. Dedicated X-ray missions are also planned. A very large X-ray observatory IXO, under joint study of NASA, ESA and JAXA, will explore the evolution of the universe using X-ray spectroscopy as a very powerful tool. |
