Researchers use origami to solve space travel challenge ANI | Updated: Dec 15, 2020 16:03 IST Washington [US], December 15 (ANI): WSU researchers have used the ancient Japanese art of paper folding to possibly solve a key challenge for outer space travel - how to store and move fuel to rocket engines. The researchers have developed an origami-inspired, folded plastic fuel bladder that doesn't crack at super cold temperatures and could someday be used to store and pump fuel. Led by graduate student Kjell Westra and Jake Leachman, associate professor in the School of Mechanical and Materials Engineering, the researchers have published their work in the journal, Cryogenics.
