NASA nudges James Webb telescope launch date after 'sudden, unplanned' vibration incident:
The James Webb Space Telescope is a very big, very overdue and very sensitive project. After years of delays, it was supposed to launch on Dec. 18 and become the newest flagship observatory. The launch has now been moved to no earlier than Dec. 22 after an incident during launch preparations.
The telescope is in the process of getting together with the Ariane 5 rocket that will escort it into space. "A sudden, unplanned release of a clamp band — which secures Webb to the launch vehicle adapter — caused a vibration throughout the observatory," NASA said in a statement Monday.
[...] NASA expects to deliver an update on the telescope's condition at the end of the week.

I have seen many projects rushed to meet a deadline. They always end up costing more, and running later. Do it right, take the time.

JWST is Too Big To Fail™ so it must be retested repeatedly at any expense.
NASA should build space telescopes in such a way that they can afford to have an entire one fail, or to have a segment fail. Or have a JWST-like unfolding telescope with lots of mechanical failure points checked at the ISS before being boosted to its final destination at L2 where it would supposedly be inaccessible for repairs.

It seems like the same mistakes will be repeated for the unambitious scaled down version of LUVOIR, because why bother learning? The contractors will still get paid.
