The XARM (X-ray Astronomy Recovery Mission) satellite is a Japanese X-ray observatory, which is to replace partially the lost Astro H (Hitomi) observatory.
XARM will carry replacements for Hitomiís two lower-energy instruments ó the Soft X-ray Imager and the Soft X-ray Spectrometer. The two Hard X-ray Telescopes and imagers will not be replaced.
NASA provides a copy of Astro-H's High-Resolution Soft X-Ray Spectrometer (SXS), which will probe matter in extreme environments; investigate the nature of dark matter on large scales in the universe; and explore how galaxies and clusters of galaxies form and evolve.
XARM carries following payloads:
The satellite might be used in conjunction with NuSTAR, which can cover the Hard X-ray segment not included in XARM.
In July 2017, the mission was apporoved. A launch is planned for 2021.
