James Webb Space Telescope team taking a rest day before sunshield tensioning begins

It is nail biting time. They have already had two limit switches didn't energize upon extension of one of the masts. Fortunately they can look at the temperature monitors and the gyroscope to tell that it made it. A similar concern is tensioning the five layers. Again, they will be able to see a drop in temperature as each layer is properly tensioned. Still holding our breath. They surely deserve some time off!
