"XRISM Mission Unveils Initial Glimpse into the X-ray Universe"

The XRISM mission, a collaboration between JAXA and NASA, has provided its first glimpse into the X-ray universe, showcasing detailed images and spectra of cosmic phenomena such as supernova remnants and galaxy clusters. The mission's instruments, Resolve and Xtend, are already exceeding performance expectations, despite an issue with Resolve's aperture door not opening fully. XRISM aims to offer new insights into the chemical composition, motion, and physical states of X-ray sources, enhancing our understanding of the universe's hottest and most energetic regions. Regular operations are expected to begin later in 2024.
