A light leak was discovered in the telescope, prompting further investigation. Upon closer examination, photos revealed small areas of damage on some of the thermal shields. The exact cause of this damage remains unclear at this time. However, it is imperative to address these issues promptly to ensure the continued functionality and accuracy of the telescope’s observations.
The telescope is equipped with 56 aluminum X-ray concentrators, each consisting of nested mirrors that direct X-rays into a detector. Positioned in front of the concentrators is a thin filter known as a thermal shield which acts to prevent sunlight from interfering with the X-ray observations. Sitting atop the concentrators is a hollow circular piece made of carbon composite called a sunshade. The sunshade is divided into six segments resembling slices of a pie and serves the purpose of keeping the concentrators from overheating in direct sunlight while also safeguarding the delicate thermal shields from damage.
To rectify these problems, experts will need to identify and address the source of the damage on the thermal shields. This may involve making repairs or replacing damaged parts altogether. Once these issues have been resolved, scientists can continue their valuable contribution to scientific research and discovery through observations using this advanced telescope technology.
