The Euclid space telescope's vision was successfully restored after a de-icing operation by the European Space Agency.

Accumulated water ice on the spacecraft's optics impaired its ability to study distant galaxies.

Engineers remotely heated a mirror, which led to a 15% improvement in light reception by the telescope.

The de-icing procedure is essential for Euclid's mission to explore dark energy and dark matter in the universe.

Identification of ice formation and the decontamination process will now be a regular part of spacecraft operations, with repetitions every 6 to 12 months.

The de-icing success provides valuable insights for future satellite missions encountering similar challenges.

Euclid is a key mission within ESA's Cosmic Vision programme, with international collaboration including contributions from NASA.
