Euclid Space Telescope Faces Setbacks in Dark Universe Mission

The Euclid space telescope, launched by the European Space Agency, has encountered technical issues during its commissioning phase. The telescope's fine guidance sensors are occasionally losing track of stars, stray sunlight is affecting early images, and X-rays are reaching the detectors due to unwanted sunlight. While these problems do not threaten the mission, they could impact its operations. The Euclid team is working on software fixes and exploring ways to mitigate the issues. Despite the challenges, initial tests are encouraging, and the telescope is expected to begin its survey of the dark universe soon.
