The X-Ray Imaging and Spectroscopy Mission (XRISM) is ready to launch on 26 August 2023 to observe the most energetic objects and events in the cosmos. In doing so, it will unveil the evolution of the Universe and the structure of spacetime. XRISM will tentatively launch from the Tanegashima Space Center in Japan at 09:34 JST / 01:34 BST / 02:34 CEST. The mission is a collaboration between the Japan Aerospace Exploration Agency (JAXA) and NASA, with significant participation from ESA. In return for providing hardware and scientific advice, ESA will also receive 8% of XRISM’s available observing time.
