9 days after the launch of the James Webb Area Telescope, NASA says it has made good progress deploying the $10 billion instrument and has now begun the vital technique of “tensioning” the sunshield.

On Monday, six motors on board the telescope started the method of totally extending the primary of 5 layers of the sunshield. These tennis-court sized layers, every made from a polyimide movie known as Kapton, will shade the instrument and permit it to chill all the way down to 50 Kelvin, which is -223 levels Celsius and simply 50 levels above absolute zero. This chilly atmosphere is vital for Webb to watch infrared gentle and detect warmth from very distant objects.

NASA’s Webb mission supervisor, Invoice Ochs, stated the primary of those 5 layers must be fully deployed by the top of Monday. The purpose is to increase the opposite 4 layers on Tuesday and Wednesday. After this time, the large sunshield—essentially the most advanced side of an intricate deployment course of—shall be full.
