Miura Fold is a rigid origami technique that can be used to fold rigid materials into flat parallelograms.
It is used to fold large solar panels in Japanese satellites before launch which can then be spread out when in space.
The folding patterns of this origami form a regularly repeated pattern of parallelograms. Each adjacent parallelogram is a mirror image of the one before and after it. When folded this way, any flat material can be packed into a compact shape which can be pulled open and closed shut by moving the opposite corners. This technique when used in folding the solar arrays reduces the number of motors required for unfolding in space, reducing the weight of the satellite.
