Description
The X-Ray Imaging and Spectroscopy Mission (XRISM) project was initiated in 2018. Following the development of onboard components, the proto-flight was conducted from 2021 to 2023 at JAXA Tsukuba Space Center. The spacecraft was launched from JAXA Tanegashima Space Center on September 7, 2023, and onboard components, including the observation instruments, were activated during the four months of the in-orbit commissioning phase. From February, the planned performance verification observations were conducted until the end of August, and the guest observations selected by JAXA, NASA, and ESA started in September. In this paper, we show initial results obtained in the performance verification phase, not only by the precise X-ray spectroscopy by the onboard X-ray micro-calorimeter but also by the wide field of view X-ray CCD camera.
