it reports NASA In its reporting on the progress of the mission. Increasing sun protection is an important part—and especially difficult. For protection, the individual foil has to be spread over five layers, and something can easily go wrong. While NASA wanted to expand sun protection on New Year’s Eve, several sensors that were supposed to monitor the installation of sun protection failed.
A little later, the successful expansion of the second web Sun Shield was reported. According to NASA, this is another important milestone. “Webb’s sun shield now resembles its full, kite-shaped shape in space,” NASA said. It took longer than expected to emerge today, but that was also because the surgical team worked meticulously after the initial difficulties and stuck to protocols designed to deal with unforeseen situations.
The two middle cantilever arms are now locked in their final positions. You’ll keep the sun protection membranes with you until the team moves on to the final step of installing sun protection: tensioning the foil. In the coming days, the team will separate each of the five layers of Sun Shield and then individually strain them to bring them to their final, taut shape. This creates space between the membranes so that heat can escape and each layer of the sun shield is cooler than the one below.
