On behalf of the Cosmic Origins program office and NASA Astrophysics congratulations to the XRISM teams at NASA and JAXA.
The X-Ray Imaging and Spectroscopy Mission (XRISM), which was formerly known as XARM, is a JAXA/NASA collaborative mission, with ESA participation. The objective of the mission is to investigate celestial X-ray objects in the Universe with high-throughput imaging and high-resolution spectroscopy. XRISM was successfully launched from the Tanegashima Space Center at 8:42 am on September 7, 2023 JST in Japan (23:42 on September 6, 2023 UT).
