Unveiling Euclid's Hidden Stars: A Commission's Celestial Quest

Euclid, a space mission aimed at understanding the secret structure and composition of the Universe, has encountered some issues during its commissioning phase. These include intermittent failures of the Fine Guidance Sensor to lock onto faint stars, stray sunlight reflecting off a thruster bracket and causing stray light interference in observations, and occasional X-ray interference from solar flares. However, teams are working on resolving these issues through software fixes, reprogramming of the survey, and repeat observations. Despite these challenges, Euclid is expected to achieve its scientific goals and provide valuable insights into dark matter and dark energy.
