"Euclid Space Telescope Successfully De-Iced from a Million Miles Away"

The European Space Agency's Euclid telescope, launched in July 2023 to study dark energy and dark matter, is experiencing optical issues due to ice formation from water absorbed during assembly. Engineers are working on a de-icing procedure to address the problem, which involves carefully heating specific parts of the spacecraft to avoid affecting its optical alignment. This issue highlights the need for ongoing maintenance, as small amounts of water are expected to be released within the spacecraft throughout its lifetime.
