Japan Aerospace Exploration Agency has agreed to cooperate with European Space Agency (ESA) on the X-Ray Imaging and Spectroscopy
Mission: XRISM.
Hiroshi Yamakawa, President of JAXA and Johann-Dietrich Wörner, Director General of ESA have signed the agreement in presence of ESA Council Delegates at the European Space Operation Center in Darmstadt, Germany on June 14, 2019.

The XRISM project, kicked off in 2018, is the seventh X-ray astronomy satellite program of the Institute of Space and Astronautical Science, JAXA. It aims at the early recovery of the prime science objective "to solve outstanding astrophysical questions with high resolution X-ray spectroscopy" of ASTRO-H whose operation was ceased in 2016.

Under the agreement, JAXA and ESA have agreed to apply the cooperation developed through ASTRO-H in XRISM. In addition to contributing to the development of one of XRISM's most important instruments, the Soft X-ray Spectrometer, ESA will also support European scientists for their participation in the XRISM project.

XRISM is currently under development and is scheduled to be launched in FY2021.
