X-ray Timing and Polarization (XTP) / GRAVITAS



The Chinese Academy of Sciences (CAS) has started to develop a future X-ray astronomy mission, called X-ray Timing and Polarization (XTP) mission. XTP is now funded for key technology demonstration and mission definition study. In the mean time, an X-ray astronomy mission called GRAVITAS has been proposed in Europe. After several discussions between CAS and MPE scientists, it is realized that XTP and GRAVITAS have quite good synergy, in terms their scientific goals and mission concepts. Therefore CAS and the Max Planck Society have set up a joint working group in October 2012 to explore the opportunity to merge XTP and GRAVITAS into a joint China-Europe X-ray mission for a launch around 2020.


  • XTP scientific objectives
  • XTP payloads
  • Possible Scenarios of XTP / GRAVITAS merge
  • Other possible international cooperation
