XRISM X-Ray Imaging and Spectroscopy Mission │ JAXA

XrismX-Ray Imaging and
Spectroscopy Mission

XRISM will perform high-resolution X-ray spectroscopic observations of hot gas plasma wind that blows through galaxies in the universe. These observations will enable us to determine flows of mass and energy, revealing the composition and evolution of celestial objects. This innovative, JAXA-led international project will be developed in collaboration with NASA, ESA, and other highly-qualified partners, and will deliver the highly-anticipated scientific new horizon of X-ray astronoy to the world.


A collection of interviews with engineers and scientists. Let's take a look behind the scenes of research and development.

XRISM Interview


XRISM is a new X-ray astronomical satellite which observes plasma in stars and galaxies. With a new generation of X-ray imaging spectroscopy technologies, XRISM will resolve mysteries regarding the formation of the universe.


By measuring the velocity and makeup of the plasma between stars and galaxies, XRISM will resolve more precisely than ever how these celestial objects are formed.
