How do you fit a giant telescope in a rocket?
What you’ll see
The James Webb telescope's mirror is six and a half metres wide, too big for any rocket. So engineers folded it like origami. Eighteen gold hexagons, with two side wings that fold back. Its sunshield, as big as a tennis court, folded into a small pack. After launch, it opened step by step over two weeks, and not one fold failed.
