IXO system studies and technology preparation

The International X-ray Observatory (IXO) is a candidate mission in the ESA Space Science Programme Cosmic Visions 2015-2025. IXO is being studied as a joint mission with NASA and JAXA. The mission concept and X-ray telescope accommodation have both been studied in the ESA Concurrent Design Facility. Competitive industrial studies will now further investigate the issues raised, and will elaborate mission concepts. In parallel the required technologies are being developed, with the main emphasis under ESA responsibility being focused on Silicon Pore Optics (SPO). A technology development plan has been made and its implementation is progressing well. The paper presents a summary of the ESA system studies of IXO and provides an overview of the related ESA led technology preparation activities.
