“In the last week, the team has learned a great deal about the spacecraft that they couldn’t have uncovered during testing on the ground.

Anticipating such occurrences, a flexible plan was developed in order to adapt as things proceed. And that strategy seems to be paying off.

“So far, the deployment of JWST has been a spectacular success. There have been a few nerve-wracking moments, but the daily reports have been welcome good news in these uncertain times. A dedicated team of engineers is going through the to-do list, item by item: There is still a ways to go, but so far, so great.”
