Great news. Looking forward to the data!
I still don’t get it.
The sun can burn myy retina as well, but unless I’m staring right at it, I can still see essentially half of space.
Yet seen a good explanation of how the orbit around L2 is done. Not like L2 has a gravity well to orbit around.
Think I read the motion is needed to keep Webb in contact with Earth.
The Webb INFRA-RED TELESCOPE is built especially to see back in time to where light from the beginning of the Universe is so red-shifted that it is invisible to normal telescopes, like Hubbell.
To do this, the mirrors and sensors are COOLED down to near absolute zero, so that any HEAT that is admitted into it’s aperture is sensed and accumulated. So it is extremely sensitive to light and heat.
The Webb has multiple shields that block out the Sun light and heat. If it were to aim at the SUN it would be destroyed and totally useless.

It’s to keep Webb from being affected by heat from the Sun Earth and Moon.................
