AXRO 2015 in Prague is International Workshop on Astronomical X-Ray Optics focused on presentation and discussion of recent and future technologies for future X-ray astronomy missions. One session is focused on astrophysical aspects of X-ray telescopes/satellites in which some review talks will be given from leading scientists in this field plus some presentations of relevant Czech scientists. The goal of the workshop is to present and to discuss recent and future technologies for X-ray astronomy missions. These missions require development of mostly innovative technologies, and we want to discuss the possibilities, the results obtained so far, and new ideas in detail. It is obvious that the requirements of future large space X-ray astronomy missions are so demanding that they need a truly interdisciplinary approach in a wide international collaboration. These technologies will include X-ray optics based on Si wafers, advanced glass forming for precise X-ray optics, but also other possible technologies and alternatives, as well as related advanced metrology, measurements and tests.
