“The current assessment of JWST’s status is
that integration and test will take significantly longer than planned. The result is a launch schedule delay and the consumption of most of the remaining funding reserves. In my opinion, the launch date and required funding cannot be determined until a new plan is thoughtfully developed and verified by independent review.” – Thomas Young
