How NASA Engineers Use Origami To Design Future Spacecraft

Summary

Origami, the Japanese art of paper folding, is revolutionizing space exploration by enabling the deployment of large, thin structures compactly. The International Space Station's solar array wings and Mars Phoenix lander's UltraFlex solar array exemplify this. NASA's Starshade project, a giant star blocker for imaging distant exoplanets, utilizes origami's mathematical folding principles to fit within a rocket and deploy with precision in space. This innovative application of an ancient art underscores the importance of thinking small to achieve big in space technology.

Q & A

What is origami and how has it been used in unexpected ways?

Origami is the ancient Japanese art of paper folding, traditionally used for creating art. It has been applied in surprising ways such as in car airbags, medical stents, and space exploration, where its folding principles allow for compact storage and deployment of large structures.

Why is origami important for space exploration?

Origami is crucial for space exploration because it enables the creation of large, thin structures that can be folded into compact forms to fit within the limited space of rockets, and then unfolded in space.

How do the solar array wings on the International Space Station (ISS) utilize origami?

The solar array wings on the ISS use a zigzag folding pattern, allowing them to be compactly stored and then deployed in space to generate power.

What is the Mars Phoenix lander's solar array called and how does it use origami?

The Mars Phoenix lander's solar array is called the UltraFlex, which uses a fan-folded design inspired by origami to efficiently pack and deploy the solar panels.

What is the Starshade project and how does it relate to origami?

The Starshade project at NASA's Jet Propulsion Lab is developing a large, star-blocking device to help astronomers image exoplanets by blocking out the starlight. The Starshade's design involves origami principles to enable its precise folding and unfolding in space.

Why is it challenging to image exoplanets directly?

Directly imaging exoplanets is challenging because the stars they orbit are much brighter, which washes out the detail of the planets, making them difficult to observe.

How does the Starshade help in observing exoplanets?

The Starshade acts as a large external occulter that blocks the light from the star, allowing telescopes to capture detailed images of the faint exoplanets orbiting them.

What is the size of the Starshade and why is its folding mechanism important?

The Starshade is about the size of a baseball diamond. Its folding mechanism is important because it needs to be compactly folded to fit inside a rocket for launch and then unfold with millimeter accuracy in space.

How does the Starshade achieve the required precision in its deployment?

The Starshade achieves the required precision through a carefully designed folding pattern and deployment mechanism that allows it to unfold in space with millimeter accuracy, positioning it correctly between the star and the telescope.

What are some other space applications of origami mentioned in the script?

Other space applications of origami include solar sails for propulsion and sun-shades for space telescopes like Gaia and the James Webb Space Telescope.

What is the significance of origami in the future of space exploration?

Origami is significant in the future of space exploration as it allows for the efficient packaging of large structures, enabling ambitious space missions with the constraint of limited rocket sizes.
