X-Ray Imaging and Spectroscopy Mission (XRISM), formerly the 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.
XRISM was lifted into orbit during the mission ‘H-IIA 202 | XRISM & SLIM’, on board a H-IIA space rocket.
The launch took place on Sept. 6, 2023, 11:42 p.m. from Yoshinobu Launch Complex LP-1.
