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.

The first group of images, taken in November 2019, shows scientists and technicians in a clean room performing an electrical checkout of the XRISM Calorimeter Spectrometer Insert (CSI), which includes the Resolve detector.

The remaining images were taken in December 2019 and show testing and calibration of a completed flight X-ray Mirror Assembly (XMA) at the 100-meter X-ray beamline facility at NASA's Goddard Space Flight Center.

Goddard developed the X-ray Mirror Assemblies, as well as the Resolve detector and many of its subsystems. XRISM is expected to launch in 2023.

The XRISM Calorimeter Spectrometer Insert (CSI) allows X-ray light focused by an X-ray Mirror Assembly at the front of the spacecraft to reach the Resolve detector. In flight, the silver cap will not be present. Part of the CSI was built using flight-quaified spare parts from the ill-fated Hitomi mission, as can be seen by the engraved "ASTRO-H" &ampmdash; an earlier name for the mission.Credit: Larry Gilbert/NASA

These electrical leads power high-performance magnets in refrigerators that work in stages to keep the Calorimeter Spectrometer Insert very cold: 50 millikelvin, or 0.05 K above absolute zero (&ampndash;459.58 F, &ampndash;273.1 C).Credit: Larry Gilbert/NASA
