We have lots of science in the next few weeks that will be using the Microgravity Sciences Glovebox (MSG).  This closed environment allows us to work in a “clean” area.  My favorite science in the MSG, so far, is the stem cell research.  This study is examining  the option of proliferating stem cells in microgravity.

The Dark Lord’s Handbook, by Paul Dale. The Dark Lord’s Handbook, Part 1 To start with, let’s do the the blurb: To become a Dark Lord is no easy thing. The simple ambition to hold dominion over the world and bend all to your will sounds straightforward but it’s not. There’s armies to raise, fortresses to build, heroes to defeat, battles to be fought, hours of endless soliloquy in front of the…

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.

🚨This is a Red Alert for net neutrality 🚨

Last December, the FCC voted to to kill net neutrality. If we do not take action, this will kill the free and open internet as we know it. The internet needs you—all of you—to make sure your voices are heard NOW.

We need all hands on deck for this one. It may be our last chance. If you’re feeling under-informed and overwhelmed about why net neutrality is so incredibly important, we have this handy guide just for you.

Here’s what you can do to save the internet:

In mid-May, the Senate will vote on a resolution to overrule the FCC using the Congressional Review Act (CRA). We only need one more vote in the Senate to win. Write or call your Senators or Representatives. You can also text BATTLE to 384-387 to get more information on how to write to your reps. You can do this, Tumblr.

Join us and dozens of your other favorite companies like Etsy, Vimeo, Reddit, and GitHub to raise awareness with the Red Alert campaign being run by Battle for the Net. Just add this small widget to your Tumblr to let your followers know how they can contact their reps. It’s as easy as copying and pasting the small line of code right into the customize theme page on the web.

This is important. This matters. It’s up to you to help.
