NASA making puncture-less tyres with shape memory for Mars
NASA is developing super-elastic tyres for its future Mars rovers that can regain its shape even after deforming up to 10%. The chainmail-based tyres made from alloys like nickel-titanium eliminate the possibility of punctures while offering traction equal or superior to conventional air-filled tyres, said NASA. The material could also be used for lightweight heat and debris shield for spacecraft.
