NASA Has Quite Literally Reinvented The Wheel


Here on Earth, getting a flat tyre is one in all life’s nice inconveniences. For NASA getting a flat tyre on Mars isn’t simply inconvenient, it’s probably catastrophic.

There is not any AA van to badist, and positively no spare tyre inside a number of million kilometres.

To overcome this distinctive hurdle a specialist staff at NASA was given a daring mission to fairly merely reinvent the wheel.

Their reply is the Shape Memory Allow Tire, a revolutionary new wheel that may’t undergo from a flat, can survive extremely difficult environments and may even be bent out of form earlier than springing again to its unique place.


Effectively what you’re taking a look at is the way forward for wheels on Mars, the Moon and probably even Earth.

Now the staff has been engaged on this for a really very long time however to rejoice how far they’ve come NASA has interviewed the engineers behind the wheel to debate how far they’ve come from the early prototypes that have been being examined virtually a decade in the past.

What is the Shape Memory Allow Tire?

It’s a revolutionary wheel design that’s made out of a fancy ‘chainmail’ metallic weave.

The materials that makes up the springs is a stoichiometric nickel titanium alloy which basically offers it some fairly exceptional properties.

In essence it permits the staff to create a set form that may soak up unbelievable forces on it and whereas it is going to change form to soak up these forces it is going to at all times return to its unique form.

Originally the staff had been working solely with spring metal which whereas helpful as a reference level, suffered badly from deformation over time.

The resolution to this, as you’ll be able to uncover within the video under, was discovered by pure serendipity.

Having solved the issue of the tyre deforming below unbelievable stresses the staff set about placing their new invention to the check.

This included testing it in Mars-like situations alongside the wheels which can be at present discovered on the Curiosity rover.

The staff even created a real-world model which might be connected to a traditional 4×4 and located that it labored completely right here on Earth too.

So what’s subsequent? Well for now the main focus could be very a lot on Lunar and Mars missions so that you’re not going to be seeing these tyres in your subsequent automotive.

That doesn’t imply that they gained’t altogether. Many of todays on a regular basis applied sciences have been born out of NASA’s badysis labs and it’s no secret that main tyre producers have additionally been working laborious on creating airless tyres.
