Since he was eight years old, Robert Salazar has been making artistic creations from folded paper.
Now, he is taking his love of origami to a different place: outer space.
Salazar works with the Jet Propulsion Laboratory of the United States space agency NASA. He says that ideas from origami can help design devices for research and exploration:
Origami offers the potential to take a very large structure, even a vast structure, and you can get it to fit within the rocket, go up, then deploy back out again. So it greatly magnifies what we are capable of building in space.
Researchers are using ideas from origami on several space agency projects.
Manan Arya is a technologist at the Jet Propulsion Laboratory. He is working on a project called Starshade. The project's goal is to fit a large object into a rocket. Once the rocket reaches the correct point in space, the Starshade opens like a flower. This large flower shape is meant to block light to permit a space telescope to better see areas close to bright stars.
Starshade, Arya says, can be used to look for planets that orbit other stars.
Seeing an exoplanet next to its parent star is like trying to image a firefly next to a search light, the searchlight being the star. Starshade seeks to block out that starlight so you can image a really faint exoplanet right next to it.
Researchers are also using ideas from origami to design a robot and a special antenna for satellites.
The robot is called the Pop-up Flat Folding Explorer Robot, or PUFFER.
It can fold itself flat to get into small spaces. Salazar says the robot can explore environments "otherwise inaccessible" to a robot. It could even be used to explore cave systems on our own planet, he adds.
Antennas on satellites capture and send communications signals.
Arya notes that the idea behind the special antenna's design is to pack it into very small satellites that are known as CubeSats. Arya says it is very useful to be able to fit large antennas into a small space:
The bigger the antenna you have, the more gain your antenna has, so it is useful to have a big antenna that gets packaged into this tiny space that unfolds out to be a large antenna. The biggest CubeSat antennas we have right now are about half a meter.
NASA's Jet Propulsion Laboratory origami-based technologies have a graceful beauty. In origami, Salazar said, art, science and engineering only have small differences.

萨拉萨尔与美国宇航局(NASA)的喷气推进实验室合作!|98(RLQt|-448fI2|。他表示,折纸手工的点子可以助力设计太空研究和探索的设备:
