How Everything Is Made on Instagram: "NASA’s Glenn Research Center engineered an airless “superelastic” tire using advanced shape-memory alloys — metals that can deform under heavy load and instantly spring back to their original shape. No air, no pressure, no risk of a flat. Originally developed for Moon and Mars rovers, these tires can survive extreme terrain, massive temperature swings, and crushing forces that would destroy normal wheels. Now the same space-born technology is being adapted f
