Story of iconic golden mirrors on James Webb Telescope and challenge of setting them up in space

India Today  

The James Webb Telescope is travelling nearly 15,00,000 kilometers away from Earth to a destination from where it hopes to look at first light, moments after the formation of our universe. The golden mirrors on the James Webb Space Telescope are a result of years of research and development. Based on the analysis, scientists recommended the beryllium mirrors for the James Webb Space Telescope. The James Webb Space Telescope mirrors vs the Hubble mirror. Unlike the Hubble space telescope, the James Webb observatory has a hexagonal shape to allow for a "high filling factor and six-fold symmetry."
