Lunch Discussion: eROSITA

Werner Becker and Salva Zavlin talked about eROSITA (extended ROentgen Survey with an Imaging Telescope Array), a new 0.2-12 keV all-sky-survey which is a joint mission of MPE and IKI, approved a few months ago. The mission will use XMM-type optics (15" on-axis resolution, 20" FOV average; 2500 cm^2) with advanced pn detectors, and survey the full sky over 4 years, with a slated launch in 2011. MPE will provide the optics (7 separate mirror modules) and detectors, IKI will provide the bus and platform, which will also contain a Lobster-style all sky monitor.
