A Japanese H-2A rocket, designated H-2A F47, launched the X-Ray Imaging and Spectroscopy Mission, or XRISM, a joint project between the Japan Aerospace Exploration Agency and NASA. XRISM is a replacement for the Hitomi X-ray astrophysics observatory, which failed about one month after launch in 2016. XRISM will perform high-resolution X-ray spectroscopic observations of the hot gas plasma wind that blows through the galaxies in the universe. These observations will enable us to determine flows of mass and energy, revealing the composition and evolution of celestial objects. JAXA’s Smart Lander for Investigating Moon, or SLIM, mission will fly as a rideshare on this launch, heading to the moon to test precision landing technology. The H-2A rocket will fly in the 202 configuration with two strap-on solid rocket boosters. Delayed from 2nd Quarter after H3 launch failure. Delayed from Aug. 27 and 28.
