Jammed door on XRISM telescope blocks low-energy X-ray observation

The X-Ray Imaging and Spectroscopy Mission (XRISM), a collaboration between JAXA and NASA, encountered a major setback when an aperture door jammed, obstructing its primary instrument, Resolve. Despite efforts to fix the issue, the telescope's ability to measure low-energy X-rays remains compromised.

Astronomers were thrilled at the prospect of uncovering new insights into the universe's formation and dark matter through the X-Ray Imaging and Spectroscopy Mission (XRISM), a collaborative project between the Japan Aerospace Exploration Agency (JAXA) and NASA.

The telescope, launched successfully in September 2023, encountered an unexpected problem: one of the aperture doors covering its primary instrument, Resolve, which detects particles, became jammed. This malfunction has caused significant concern among scientists.

Efforts to remotely open the jammed door have been unsuccessful. NASA has confirmed to Space.com that the intended 18-month operation of the telescope is now uncertain, as officials deliberate on the best course of action. This is particularly disappointing since XRISM was expected to serve as a powerful successor to NASA's older Chandra X-ray Observatory, which is facing potential budgetary constraints threatening its operations.

Despite the issue, there is a positive aspect to Resolve's door malfunction. While the instrument cannot measure low-energy X-rays with the door closed, it remains capable of detecting high-energy X-rays, as these wavelengths are unaffected by the obstruction.

However, the situation remains disheartening for scientists who had anticipated groundbreaking advancements in X-ray astronomy. "I am absolutely gutted that we can't see below 2 keV," Simionescu told Space.com.
