Very hard to build structure to withstand launch and resist distortion during orbit,with temperatures near 0 degrees Kelvin. Lots of challenging engineering going on in JWST with exotic composite materials and the like, especially at such grand scale.

Oh!

Whew! For a moment there I thought the nutjob U.S. Senator from Virginia was getting a space telescope named after him.

Are they going to put the whole optical assembly together on the ground and make sure the focus is correct before putting it into space this time?

I hoped they learned a GOOD lesson from Hubble. Do NOT skimp on testing on the ground, even if it seems expensive. It’s a heck of a lot more expensive to have to send someone up into space to fix it.
