"NASA and JAXA Collaborate to Resolve X-ray Astronomy Satellite Glitch"

The Japanese X-ray astronomy satellite XRISM, developed with contributions from NASA and ESA, is performing well in orbit, except for an issue with one of its instruments' aperture door. Despite the door not opening as intended, the spacecraft's two main instruments, Resolve and Xtend, are meeting or exceeding most requirements. NASA and JAXA are working to troubleshoot the aperture door issue, with hopes that it will eventually open, allowing the instrument to operate at full capacity.
