Installing the first layer of the sunscreen on the James Webb Space Telescope
To date, the new space telescope, James Webb got five protective layers from solar radiation. They must cover the optics and instruments. In August, the first deployment tests are being prepared.
The operation of all layers reduces the temperature between the hot and cool sides by 570 degrees Fahrenheit. Each next is made of Kapton with a low temperature regime. All installed in June-July 2017. Let's not forget that the launch of the telescope will be an important event, as it is able to peer 13.5 billion years into the past.
Installing five layers of screen. Everyone seems as thin as human hair. The layers are made by NeXolve Corporation in Alabama and prevent background solar heat from affecting infrared sensors. Visor in size reaches the parameters of a tennis court, but the thickness resembles human hair.
James Webb - space observatory and the last word in the development. In power surpasses the famous Hubble. His goal - the study of distant objects in the early space. With it, expect to get the first images of ancient galaxies and the first stars.
Sun layers function to reduce the temperature between the heated and cool sides by 570 degrees Fahrenheit. Each next layer has a lower level of heating.
