I'm starting to think this mission is cursed...

The launch readiness date for the James Webb Space Telescope is moving to no earlier than Dec. 22 to allow for additional testing of the observatory, following a recent incident that occurred during Webb’s launch preparations.

The incident occurred during operations at the satellite preparation facility in Kourou, French Guiana, performed under Arianespace overall responsibility. Technicians were preparing to attach Webb to the launch vehicle adapter, which is used to integrate the observatory with the upper stage of the Ariane 5 rocket. A sudden, unplanned release of a clamp band – which secures Webb to the launch vehicle adapter – caused a vibration throughout the observatory.

Isn't that what they said about Hubble?

At least Hubble was fixable.

If it turns out to not be fit for its original mission it could be expended in a DART 2 mission?  ;)

Now if the rocket works and the satellite  opens correctly.

Iheard there is another delay, communication between the rocket and control.  Dec24 NET.

Teams are working on "a communication issue between the observatory and the launch vehicle system," NASA shared in an online post. The agency will provide an update about the telescope on Friday.

Telescope is inside rocket fairing and the rocket is currently being moved to the launch platform.

Its happening ITS HAPPENING

I'm a cynic, and I freely admit it, but I'll believe it when I actually see it go up. Until then, it's almost like vaporware.

And what the heck do they mean that the communication problem between the launch vehicle and the observatory is "mostly resolved?" They can talk to one another 1/2 the time? Eighty percent of the time?  Nine out of every ten words go through?

If it goes up and works out, it definitely will make a heck of a Christmas present.

Agreed.  Let's hope tomorrow morning's launch is the first of many, many successful steps leading up to it starting its mission.

Its 12:47 am in NZ - launch is in 33 minutes..... and I am starting to get nervous!!
If you're not a scientist but you think you've destroyed the foundation of a vast scientific edifice with 10 minutes of Googling, you might want to consider the possibility that you're wrong.
