As we have described before, there is humidity – water – in every spacecraft. And this humidity will turn to ice in the cold and vacuum of space. Euclid is no exception to this. If this humidity collects on optical surfaces like mirrors, it will affect the optical performance of a space telescope. For this reason Euclid will undergo a second targeted de-icing process over the next days.
