Did you know that origami has influenced space exploration? Rockets have a limited amount of space inside them, meaning it can be difficult to get large objects out into orbit. Something like the 25-meter solar array shown above would be impossible to safely store inside a rocket at full size!
This origami pattern solves this problem by allowing the array to be stowed compactly during launch, then unfolded to its full size once in space. Additionally, since the pieces of the folded design are all connected, electrical circuits can run throughout, allowing for power generation from the panels.
For more information on the design of the solar panel, see these publications:

This Instructable will show you how to make your own paper model of this flasher pattern, which unfolds to nearly 50 times its compacted surface area!

Step 1: Print
Print or copy the fold pattern onto a piece of paper.
Step 2: Cut
Cut along the outer edges of the square pattern.
Step 3: Crease the Pattern
Using the line colors as a guide, fold along the crease lines:
Blue lines = mountain folds
Red lines = valley folds
It is easiest to focus on one fourth of the pattern at a time, and work your way around. Use the images above to help you, or use the PDF version below.
Step 4: Collapse the Pattern
Carefully compact the paper from the outside edges, letting the existing creases guide you to the final state. The outside edges should almost do a 180° from where they were in the unfolded state.
Step 5: Open the Pattern
Now, pull on the corners of the paper and watch it expand!
You can re-collapse the pattern and expand it as many times as you would like.
