So, since there’s no shortage of brilliant minds working for NASA, they’ve managed to design “superelastic” tires based on chainmail armor. 'I wanted to create a piece that's completely unnoticeable and so familiar, you're just going to walk past it. For more information on Technology Readiness Level, please visit: http://www.nasa.gov/content/technology-readiness-level Secondly, because they conform to the terrain and do not sink as much as rigid wheels, they can carry heavier payloads for the same given mass and volume. … Wheels on the Moon. Evolving since the days of Apollo, NASA engineers started examining tire designs back in the 1960's for use on the surface of the Moon.
So, they set about developing several Spring Tire prototypes to improve:While the tires performed well, there was a problem with the steel wires deforming when rolling over punishing simulated Martian terrain at NASA's Jet Propulsion Laboratory (JPL). Tech Reveü. Thin tread strips were attached to the carcass to enhance flotation in soft lunar soil.While NASA was developing rovers to send to Mars, there was also interest in taking a new look at returning to the Moon.
Lastly, because the compliant tires can absorb energy from impacts at moderate to high speeds, they can be used on crewed exploration vehicles which are expected to move at speeds significantly higher than the current Mars rovers. "The Superelastic tire offers traction equal or superior to conventional pneumatic tires and eliminates the possibility of puncture failures, thereby improving automobile safety," NASA said.
Take a look to find out. It performed impressively on the punishing track.So, why are shape memory alloys the key to success for this new generation of spring tires? There are three major benefits to developing high performing compliant tires that are capable of performing in a Martian or Lunar environment. NASA goes back to the middle ages for its latest tire design . While they were vastly different, they were all focused on moving hardware and astronauts across the lunar surface. Report. It has to do with the atomic structure. To solve this problem, NASA has gone back to the middle age to create a superelastic tire. The game changing material that dramatically advanced the development of spring tires was After building the shape memory alloy tire, Glenn engineers sent it to JPL's Mars Life Test Facility. Tire development for space exploration has been a focus of research at NASA Glenn for a decade. Follow. NASA Glenn engineers rebuilt Apollo era tires and developed new designs using newer materials and technology to better function on a lunar surface.A little over a year after the Mars Curiosity Rover landed on Mars, engineers began to notice NASA Glenn engineers thought their work on Spring Tires might be a new and better solution for exploration rovers on Mars. And/or collecting natural fibers, wet clay-like materials that could then dry and become chunks trapped inside.like bricks!have something to add?

I can see the mesh collecting particulate materials inside of the “tire” and becoming very heavy and “bogged down” and sinking the vehicle up to it’s axils….

This manned vehicle used four large flexible wire mesh wheels with stiff inner frames to prevent over-deflection. NASA researcher preps model wing for a blast from the "bug gun."
