Scientists and engineers at NASA are using origami techniques to help solve a fundamental dilemma facing spacecraft designers: How do you take a big object, pack it into a small container for rocket launch, and then unpack it again once it arrives in space — making sure nothing breaks in the process.
The folded sheet looks a bit like the folded maps you can buy at gas stations. But instead of multiple steps to unfold it, all you need to do is grasp the corners of the paper and pull. It's simple — and simplicity is key when designing a spacecraft.
"If I was deploying [a solar panel] in space," Trease says, "I would only need one motor to do that deployment. That's the beauty of the design."
And the usefulness of origami in space exploration doesn't end with solar panels.
For example, we can now print things like electronic circuits, solar cells and displays directly onto sheets of paper, Trease says, and scientists are devising ways take these sheets and fold them up into into useful instruments — such as seismometers or atmospheric detectors.
"What really excites me is the idea of just sending the entire printer up into orbit," Trease says. Then if you needed a different sensor, he explains, you could just upload the design and print out a new one in space.
