Inspiration Of The Day: Watch Me Http://love.whrt.it/ditum

Our pale blue dot, planet Earth, is seen in this video captured by NASA astronaut Jack Fischer from his unique vantage point on the International Space Station. From 250 miles above our home planet, this time-lapse imagery takes us over the Pacific Ocean’s moon glint and above the night lights of San Francisco, CA. The thin hue of our atmosphere is visible surrounding our planet with a majestic white layer of clouds sporadically seen underneath.

The International Space Station is currently home to 6 people who are living and working in microgravity. As it orbits our planet at 17,500 miles per hour, the crew onboard is conducting important research that benefits life here on Earth.

Yahoo Finance Adds Cryptocurrency Trading Capabilities

Last year, Yahoo Finance added over 100 cryptocurrency quote pages across all platforms globally, giving audiences the unique ability to track coins and stay informed on the digital currency craze.

Yahoo Finance is now allowing users to act on that information, and trade cryptocurrency directly through its platform. The new feature, launched this week on the iOS app, allows users to buy and sell a variety of cryptocurrencies by linking their account – via an integration with our partners at TradeIt –  including Bitcoin, Ethereum, Litecoin and Dogecoin.  Android, desktop and mobile web are coming soon.

“As the leading provider of financial data, insights, and editorial content, we are constantly looking for ways to better serve audiences on the Yahoo Finance platform,” said Joanna Lambert, General Manager of Finance & Tech at Oath. “We first launched our integration with Trade It one year ago, allowing people to trade on Yahoo Finance for the first time ever.  We’re excited to expand this offering to cryptocurrencies, further connecting our passionate community of investors with relevant utilities on our trusted platform.”

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.
