The new rover tires are made from a nickel-titanium alloy. This alloy can change form and can also return to its original shape. It is also super-elastic and that is what helps it 'remember' its original shape.

It can adapt easily to both sand and rock and rearrange itself to move as required. In the process the tire is not damaged since the material itself changes shape to accommodate any other material it rolls over, there is no blunt force, abrasion or friction - things that can otherwise damage a tire.

NASA plans to use this tire to help with space mobility and who knows, it might see itself become tires on some vehicles on Earth in the future.
