NASA goes back to the middle ages for its rover tire design
The Mars Curiosity rover has been a big success, but NASA's modern tech couldn't save its tires from breaking down in the harsh conditions of Mars. For future missions, the agency has gone back to the age of knights. Based on the principals of chainmail armor, the "Superelastic" tires can withstand more deformation than any other non-pneumatic tire. At the same time, they could potentially withstand extraplanetary abuse and provide better traction for next-generation rovers.
