XRISM is a collaborative mission between JAXA and NASA, with contributions from over 70 institutions in Japan, the U.S., Canada, and Europe. NASA Goddard developed the Resolve detector and many of the instrument subsystems, together with the two X-ray Mirror Assemblies. Goddard is also responsible for the Science Data Center, which developed analysis software and the data processing pipeline, as well as support for the XRISM General Observer Program.
