NASA registered a new patent, and it has nothing to do with rockets, but it is related to scientific exploration beyond the planet Earth.
The American aeronautical technology development agency created the superelastic tire, which can be used in vehicles built to cross the Martian or lunar terrain, and even will be used in land vehicles.
Inspired by the chainmail used as protection by soldiers in the medieval times, NASA and Goodyear created this tire without air, the structure is made of nitinol, an alloy of nickel and titanium. This alloy has a memory capacity, i.e., returns to its original shape even after undergoing extreme pressure resisting permanent deformation during a considerable period of time.
This makes it the ideal tire to cross geological terrains with obstacles like the surface of Mars, which could cause holes in the ordinary tires. The superelastic tire could also be used on Earth in all-terrain vehicles in both military applications and emergency situations but also in all kinds of civilian vehicles that need to traverse tricky terrain.
