Origami, the Japanese tradition of paper folding may address a consistent challenge for the engineers at NASA’s Jet Propulsion Laboratory. How do you pack a significant amount of spacecraft into a tight place?
The ancient art is key to the design of NASA’s Starshade, and now origami is being explored by NASA for other projects.
What is Starshade?
Fully functioning, Starshade can spread out to an 85-foot diameter. That’s about the size of a baseball diamond.
But flying a baseball diamond sized object into space is a challenge, so engineers are using origami as a way to shrink the large spacecraft for transportation.
While Starshade is still just in the concept stages, NASA’s Jet Propulsion Lab is actively exploring origami for other projects as well.
The Brains Behind the Project
“A huge part of my job is looking at something on paper and asking, ‘Can we fly this?'” said Manan Arya, a technologist working on Starshade.
Arya’s Ph.D. thesis looked into the use of origami in space structure.
“Once I realized this is how you fold spacecraft structures, I became interested in origami,” Arya said. “I realized I was good at it and enjoyed it. Now I fold constantly.”
The Starshade project still has a long way to go, but Arya believes we could see space origami very soon.
CubeSats are one promising application. CubeSats are briefcase-sized satellites that will likely require a collapsible antenna.
“That’s an area where I see origami having an increasing role,” Arya said.
The JPL engineers are also working on a robot called PUFFER. PUFFER’s collapsible body is made from a folding circuit board embedded with fabric. When in use, it pops-up and can climb over rocks or squeeze down under ledges.
