X-Ray Astronomy Recovery Mission (XARM) is a replacement for the Hitomi satellite that malfunctioned few weeks after the launch.
Smart Lander for Investigating Moon (SLIM) is a lunar probe that will target a landing on a small crater in Mare Nectaris, an area located near the moon’s equator on the side facing Earth.
Il satellite verrà mandato in orbita terrestre a 550 km di quota e raffreddato a elio liquido a temperature vicino allo zero assoluto per poter vedere ai raggi X. Dopo che tutto l’elio sarà evaporato, 3 anni circa, la missione primaria terminerà.
Dalla pagina della missione del sito della NASA, sembra che sia stata posticipata ad aprile 2023:
Si legge in un box a destra: “The X-ray Imaging and Spectroscopy Mission (XRISM) is a JAXA/NASA collaborative mission with ESA participation. XRISM will investigate the X-ray sky using high-resolution spectroscopy and imaging and is expected to launch from Japan by April 2023.”
