XRISM will study the Universe in X-ray light with an unprecedented combination of light collecting power and energy resolution – the capability to distinguish X-rays of different energies. The mission will provide a picture of the dynamics in galaxy clusters, the chemical make-up of the Universe and the flow of matter around accreting supermassive black holes (Active Galactic Nuclei or AGN), among many other topics.
The spacecraft will be launched on 26 August 2023 from the Tanegashima Space Center, Japan, with hardware components and support for science management and planning provided by ESA. In return, ESA will be granted 8% of XRISM's available observing time, to be allocated to scientists affiliated to institutions in ESA Member States.
