The Webb telescope mockup weighs just over 5600 lbs. and is slowly and carefully lifted because it cannot undergo a hard impact due to its heavy weight and the delicate nature of the precision attachment points to the sunshield model.

Engineers and technicians at Northrop Grumman, Redondo Beach, Calif., lift a full-size mockup of the Webb telescope's primary mirror support structure from a rollover fixture onto a full-size model of the sunshield. The operation enabled engineers to check clearances between these elements and the sunshield layers.
