  1. I thought JWST was supposed to be in the shadow of the Earth always (L2). Why is there still sunshine into the shield? Update: it was explained around 23:00. Basically L2 point would be in constant shadow of Earth but they want to use solar panels for electricity so they don't actually go exactly to L2 but instead orbit around it at a distance that gets sunlight to the solar panels.

  2. 27:00 I understood that he had worried during the planning and as they think they have solved all known problems, there's nothing else to worry. Of course, the changes are that something unforeseen goes bad that worrying about that is not going to change anything so there's no point to worry anymore.
