The Euclid Space Telescope of the European Space Agency is now back to its regular operations after last week's ice buildup due to water droplets that entered the spacecraft.

This massive effort now brings the highly sensitive VISible instrument (VIS) back to life, with the team's new tactic helping the telescope device return to full operational capabilities. 

ESA's Euclid mission is to learn more about dark matter seen in space, with the agency looking more into the existence of dark energy as part of the universe. 

Euclid Space Telescope's Sight Restored After Deicing

ESA announced that it successfully restored the full operational capabilities of the Euclid Space Telescope after deicing the lens affected by the buildup after water entered it.

The operations were announced last week in an attempt to clear the VISible Instrument's blocked views of space, affecting its quality and seeing distant stars clearly because of the hiccup. 

The team claimed that its attempt focused on heating up a mirror by around 34 degrees warmer, a procedure it spent months figuring out was the best action to take. 

In this venture, the team was able to heat the mirror without interfering with its finely tuned mission's calibration or causing further contamination of the lens.

Little Bit of Ice Greatly Affects Euclid

Europe's space agency said that the little bit of water that turned to ice greatly affected Euclid's ability to see the cosmos clearly, with the light coming into VIS gradually decreasing as the ice remained. 

"It was an enormous team effort over the last months to plan, execute, and analyse the heating of selected mirrors onboard Euclid, resulting in the fantastic result we see now," said Ralf Kohley, Euclid Instrument Scientist and in charge of the anomaly review board.

Euclid and its Mission

The European Space Agency's (ESA) Euclid space telescope was launched into space in July 2023. It is meant to study more of the dark matter present in space, especially as it remains an unknown entity in the great beyond.

By 2027, it will be joined by NASA's Roman Space Telescope to center on a collaborative mission to learn more about this mysterious energy. 

By August, Euclid had reached the point in space where it would look into various spots in the vast cosmos. The space telescope shared its first images using the VISibe Instrument.

This allows researchers and astronomers to capture super-sharp images of the multitudes of galaxies present, with the capability to measure their shapes. Euclid helps uncover more information behind unknown ones. 

Euclid's mission is important for the astronomical world, particularly as it aims to uncover the secrets behind dark matter and why it was theorized to make up a massive part of the universe we know.

However, it could not do so with water-damaged lenses, especially as ice had already built up here. This latest method successfully removed it for the telescope's continued survey of the great beyond.
