Our Vision for BiOrigami
Applying bioengineering to space exploration
BiOrigami can improve mission capabilities by conserving volume
We asked planetary science experts how self-folding structures could aid space exploration. Here is what they said.
When launching satellites, probes, telescopes, and manned spacecraft into orbit, volume is everything. Because rockets need to fly through the atmosphere at supersonic speeds, payloads need to be packed into sleek, aerodynamic fairings at the tip of the rocket. A typical fairing has a diameter of just 5 meters. Carrying up large structures like solar panels and telescope mirrors requires the use of compact folding for launch.
A size comparison of the International Space Station and a 5 meter-diameter payload fairing cross section. Most medium and heavy launch vehicles support a maximum fairing diameter of 5 meters. ISS image retrieved from www.historicspacecraft.com.
Origami is already used heavily in the space industry. To name just one example, the Ultraflex Solar Array used on the Mars Phoenix Lander deploys by unfolding many isosceles triangles into a circle.
Top: The Ultraflex Solar Array System in its folded and unfolded state. Bottom: The Ultraflex Solar Array System as deployed on the Mars Phoenix Lander. Images are from the Orbital ATK Ultraflex fact sheet (top) and NASA/JPL/UA/Lockheed Martin (bottom).
Our project goal is to develop the concept of origami in space further, by making the structures (1) self-folding and self-unfolding, and (2) produced biologically, which allows for in-situ resource utilization. We envision many possible uses for BiOrigami. Repositories of hundreds of different structures could be sent on manned missions flat-packed as reams of paper for on-demand use by astronauts. Self-folding structures could be used to deploy inflatable habitats, solar arrays, sun shields, and more. Small, self-unfolding paper-based probes could be dispersed around the Martian surface and relay weather information, relying on solar power.
