headed for space, where it began its mission to observe the Universe and measure its expansion over time. The commissioning process began well as the mission team spent weeks testing and calibrating the observatory, then flew the mission out to Lagrange Point 2 . The telescope focused its mirrors, collected its “first light,” and theit took were breathtaking! Unfortunately, Euclid hit a snag when its Fine Guidance Sensor failed to lock onto its “guide stars.”, thanks to a software patch.
The Euclid mission is one of the most sophisticated and precise observatories ever launched. To ensure accuracy, the telescope must point to a new field in the sky every 75 minutes with extreme stability. To do this, the spacecraft relies on the Fine Guidance Sensor , a completely new instrument that uses optical sensors to image the sky from the sides ofLoopy star trails show the effect of Euclid’s Fine Guidance Sensor intermittently losing its guide stars.
The software patch was tested first on Earth with an electric model of Euclid and a simulator, then for ten days in orbit. As Micha Schmidt,– went back to the drawing board and revised the way the Fine Guidance Sensor identifies stars. After a major effort and in record time, we were provided with new on-board software to be installed on the spacecraft.
“I want to thank all our teams of experts involved in successfully completing the challenging commissioning phase, including the Euclid Consortium, engineers and industry. Now comes the exciting phase of testing Euclid in science-like conditions, and we are looking forward to its first images showcasing how this mission will revolutionize our understanding of the dark Universe.”

Combining a bulky chain with a stable polymer to enhance liquid crystal performanceFrom laptop screens to navigation systems, liquid crystals are ubiquitous in modern life. These materials flow like liquids, but their molecules align with one another in a way that resembles the orientational order of a crystal. Electrically switching between different molecular orientations—or phases—in a liquid crystal changes how the material transmits light, hence their use/utility in visual displays.
