Just a few days ago NASA announced that Webb had been hoisted and secured on top of the Ariane 5 rocket that will launch it to space. It’s folded into the 5.4 meter/17.7ft. fairing of the Ariane 5 for launch, the largest rocket fairing NASA could find. 

NASA said today in a launch update that:

“The James Webb Space Telescope team is working on a communication issue between the observatory and the launch vehicle system. This will delay the launch date to no earlier than Friday, Dec. 24. We will provide more information about the new launch date no later than Friday, Dec. 17.”

Wishing you clear skies and wide eyes.
