Mirror Quadrants for XRISM
Released on January 30, 2020
The X-ray Imaging and Spectroscopy Mission (XRISM, pronounced “crism”) is a collaboration between the Japan Aerospace Exploration Agency (JAXA) and NASA, along with ESA participation, to investigate the X-ray universe using high-resolution imaging and spectroscopy. XRISM features two instruments: Resolve, an X-ray calorimeter spectrometer, and Xtend, an X-ray imager.
These images, taken in June 2019, show completed elements of one XRISM flight X-ray Mirror Assembly (XMA). Each XMA includes both a primary and a secondary mirror. Each mirror has four quadrants with 203 nested foil mirror segments apiece, for a total of 1,624 mirror segments in one XMA.
NASA’s Goddard Space Flight Center developed the X-ray Mirror Assemblies, as well as the Resolve detector and many of its subsystems. XRISM is expected to launch in 2023.
