Suffering is Always ‘Optional‘

“Suffering stems from unconsciously reacting to a ‘believed in’ story (imagined, personal narrative) strongly held in the mind that takes you out of the Now.”  ~Anon I mus (Spiritually Anonymous)

Tax avoidance may be legal but it’s bankrupting our social order | Owen Jones

Tax avoiders rely on legal loopholes, at the expense of a state they refuse to contribute to, says the Guardian columnist Owen Jones

In the coming days, you will hear this response from the defenders of our rotten status quo. “What the Paradise Papers has exposed is legal, so what is the problem?” They have an agenda, of course. They want to demonise the very concept of taxation because they want to roll back the state and construct a free-market “utopia” which, in practical terms, would be dystopian for the vast majority.

Owen Jones highlights what the Paradise Papers reveal in how elites are refusing to help the populace and how the loopholes are hurting society. As Jones goes on to note on Britain:

The state is punitive when it comes to, say, benefitfraudsters or thousands of young people criminalised for arbitrarily banned drugs, but uses kid gloves when it comes to our shameless uber-wealthy elite. The colossally destructive behaviour of the rich is permitted; the infractions of the poor are deemed intolerable.

As Owen Jones illuminates current society has been set as following:

One rule for those at the top, another for everyone else. 

In this age of austerity, in which public services are being axed, the Pararise Papers highlights a greater ill in the practice of austerity as tax avoidance is set as such. As Owen Jones end his article:

A democratic revolution is surely coming in the western world, and this shameless, decadent elite only have themselves to blame.

Reinventing the Wheel

Planning a trip to the Moon? Mars? You’re going to need good tires…

Exploration requires mobility. And whether you’re on Earth or as far away as the Moon or Mars, you need good tires to get your vehicle from one place to another. Our decades-long work developing tires for space exploration has led to new game-changing designs and materials. Yes, we’re reinventing the wheel—here’s why.

Wheels on the Moon

Early tire designs were focused on moving hardware and astronauts across the lunar surface. The last NASA vehicle to visit the Moon was the Lunar Roving Vehicle during our Apollo missions. The vehicle used four large flexible wire mesh wheels with stiff inner frames. We used these Apollo era tires as the inspiration for new designs using newer materials and technology to better function on a lunar surface.

Up springs a new idea

During the mid-2000s, we worked with industry partner Goodyear to develop the Spring Tire, an airless compliant tire that consists of several hundred coiled steel wires woven into a flexible mesh, giving the tires the ability to support high loads while also conforming to the terrain. The Spring Tire has been proven to generate very good traction and durability in soft sand and on rocks.

Spring Tires for Mars

A little over a year after the Mars Curiosity Rover landed on Mars, engineers began to notice significant wheel damage in 2013 due to the unexpectedly harsh terrain. That’s when engineers began developing new Spring Tire prototypes to determine if they would be a new and better solution for exploration rovers on Mars.

In order for Spring Tires to go the distance on Martian terrain, new materials were required. Enter nickel titanium, a shape memory alloy with amazing capabilities that allow the tire to deform down to the axle and return to its original shape.

These tires can take a lickin’

After building the shape memory alloy tire, Glenn engineers sent it to the Jet Propulsion Laboratory’s Mars Life Test Facility. It performed impressively on the punishing track.

Why reinvent the wheel? It’s worth it.

New, high performing tires would allow lunar and Mars rovers to explore greater regions of the surface than currently possible. They conform to the terrain and do not sink as much as rigid wheels, allowing them to carry heavier payloads for the same given mass and volume. Also, because they absorb energy from impacts at moderate to high speeds, there is potential for use on crewed exploration vehicles which are expected to move at speeds significantly higher than the current Mars rovers.

Airless tires on Earth

Maybe. Recently, engineers and materials scientists have been testing a spinoff tire version that would work on cars and trucks on Earth. Stay tuned as we continue to push the boundaries on traditional concepts for exploring our world and beyond.
