X-ray Imaging and Spectroscopy Mission (XRISM)

The X-ray Imaging and Spectroscopy Mission (XRISM) is a JAXA/NASA collaborative mission, with ESA participation. Equipped with an X-ray micro-calorimeter and X-ray CCD camera, identical to those on Hitomi, specializing in soft X-ray imaging spectroscopy. XRISM's aim is to develop the world of high resolution X-ray spectroscopy.
