"The first deployment takes place 33 minutes after liftoff, when it releases its solar panel. That will be followed by its first midcourse correction burn, called MCC-1a, which will take place 12.5 hours after liftoff. Those two events are the most time-sensitive ones for the spacecraft"

"there are 344 single-point failures in the spacecraft, 80% of which are associated with deployment mechanisms"

"The sunshield, for example, includes 140 release mechanisms, 70 hinge assemblies, eight deployment motors, about 400 pulleys and 90 cables that are a total of 400 meters long"

"A maneuver 29 days after launch will place JWST into its final halo orbit"
