James Webb Space Telescope reaches launch pad for Christmas liftoff
The James Webb Space Telescope is due to launch on Saturday (Dec. 25) during a 32-minute window that opens at 7:20 a.m. EST (1220 GMT). The massive observatory will blast off from Kourou, French Guiana, atop an Ariane 5 rocket operated by European launch provider Arianespace. You can watch launch coverage live at Space.com beginning at 6 a.m. EST (1100 GMT) courtesy of NASA or you can watch directly at the agency's website.

Damn I missed the launch. I just assumed it would be pushed back again!
I was watching Scott Manley's video yesterday on Webb and I think he said it will take about 2 weeks to get into the final orbit out past the moon-earth L2 point. They undershot on the upper stage because there was a risk it would be an over-performing engine and send the telescope out past it's orbit, with too much energy for the telescope to use it's fuel to return.

Yeah, I'd put aside some time in 2029 too.
