Yea, that's a LOT of deployment/automation that all has to work perfectly.Looking forward to this launch, I really hope all goes to plan.

I hate, hate, hate to say this but this bird is so damm complex it might be doomed winding up as a $2 billion paperweight.Delayed again:
An “incident” with the James Webb Space Telescope has occurred
NASA is leading an anomaly review board to investigate and conduct additional testing.arstechnica.com
At some point you have wonder if it would've been cheaper to just build two, so if they first one failed just send it's replacement, instead of testing and testing and testing.I hate, hate, hate to say this but this bird is so damm complex it might be doomed winding up as a $2 billion paperweight.
Had been seeing some articles about this and meaning to learn more. Giddy about what it could bring us. I'm not sure that we'll get another "whoa" moment like the Hubble Deep Field image, but you never know.
A review board, headed by NASA, made the decision that additional testing is required to ensure that these vibrations haven’t damaged any components in the observatory. Therefore, the date of the launch is now moved from December 18 to “no earlier than” December 22.
the vibrations could be of a larger magnitude or in a different direction than designed for.Uh, how can 'vibrations' be a problem for a satellite that is going to be launched into space aboard a thundering rocket ship??
Well, they won't be of a larger magnitude, but they could have been in a plane that could do more damage. Max acceleration threshold should be pretty high for a n unmanned launch package.the vibrations could be of a larger magnitude or in a different direction than designed for.
Very. It's infrared though right? Or is it visible and infra?With a cost of $10 billon dollars lets hope the launch goes well.
Just how much more powerful is it compared to the Hubble? Can't wait to see some of the pictures it captures.
I wonder if it's a timing related thing to get to it's L2 location?Seems a bit crazy to do that on Christmas eve though, you'd think they would have just waited until January.

https://en.wikipedia.org/wiki/James_Webb_Space_TelescopeThe primary mirror of JWST, the Optical Telescope Element, consists of 18 hexagonal mirror segments made of gold-plated beryllium which combine to create a 6.5 m (21 ft) diameter mirror — considerably larger than Hubble's 2.4 m (7 ft 10 in) mirror. Unlike the Hubble telescope, which observes in the near ultraviolet, visible, and near infrared (0.1 to 1 μm) spectra, JWST will observe in a lower frequency range, from long-wavelength visible light through mid-infrared (0.6 to 28.3 μm), which will allow it to observe high redshift objects that are too old and too distant for Hubble to observe.
how much did all the testing costs?At some point you have wonder if it would've been cheaper to just build two, so if they first one failed just send it's replacement, instead of testing and testing and testing.
Not sure exactly, but from podcasts and stories I've read it was a massive chunk of the expense and delay.how much did all the testing costs?
probably a shitton. they have a full-size cryogenic chamber to test the damn thing :O :O :Ohow much did all the testing costs?
wtf sunk cost?!probably a shitton. they have a full-size cryogenic chamber to test the damn thing :O :O :O
