Next Generation Spacesuit like Second Skin

Scientists from MIT have designed a next-generation spacesuit that acts practically as a second skin, and could revolutionize the way future astronauts travel into space. (Photo : Jose-Luis Olivares/MIT)
Astronauts are used to climbing into conventional bulky, gas-pressurized spacesuits, but this new design could allow them to travel in style. Soon they may don a lightweight, skintight and stretchy garment lined with tiny, muscle-like coils. Essentially the new suit acts like a giant piece of shrink-wrap, in which the coils contract and tighten when plugged into a power supply, thereby creating a “second skin.”
"With conventional spacesuits, you’re essentially in a balloon of gas that’s providing you with the necessary one-third of an atmosphere [of pressure,] to keep you alive in the vacuum of space," lead researcher Dava Newman, a professor of aeronautics and astronautics and engineering systems at MIT, said in astatement.
"We want to achieve that same pressurization, but through mechanical counterpressure - applying the pressure directly to the skin, thus avoiding the gas pressure altogether. We combine passive elastics with active materials. … Ultimately, the big advantage is mobility, and a very lightweight suit for planetary exploration."
Newman, who has worked for the past decade on a design for the next-generation spacesuit, describes the new garment in detail in the journal IEEE/ASME: Transactions on Mechatronics.
The MIT BioSuit’s coils, which are a main feature of the outfit, are made from a shape-memory alloy (SMA). At a certain temperature, the material can “remember” and spring back to its engineered shape after being bent or misshapen.
Skintight suits are not a novel idea, but in the past scientists have always struggled with the question: how do you get in and out of a suit that is so tight? That’s where the SMAs come in, allowing the suit to contract only when heated, and subsequently stretched back to a looser shape when cooled.
Though the lightweight suit may not seem at first like it can withstand the harsh environment that is outer space, Newman and his colleagues are sure that the BioSuit would not only give astronauts much more freedom during planetary exploration, but it would also fully support these space explorers.
Newman and his team are not only working on how to keep the suit tight for long periods of time, but also believe their design could be applied to other attires, such as athletic wear or military uniforms.
"An integrated suit is exciting to think about to enhance human performance," Newman added. "We’re trying to keep our astronauts alive, safe, and mobile, but these designs are not just for use in space."


Scuse you, Dava Newman is a FEMALE professor at MIT. 

(fyi, I passed out in a vacuum chamber wearing an earlier version of this suit. =D)

The pose would mislead you. This was actually one of the nicest rattlesnakes I’ve ever met. He mostly just wanted to crawl under me to hide. I was a wimp and backed away, though.

nuno, if you just walkaway then I WILL get a sumburm! Prodcure me a parasoul, FHOOST away ALL of sunray immedeat 9.8/10 Someone insteadidea, is move to North and CLOIUDY place! Yoo haul

Friends, this is why you keep things (specifically work you’ve done) long after you think they’ve lost their relevancy.

I dropped the bluebird nest-box job off of my resume a while back due to space issues, but it documents my familiarity with nest boxes and carpentry ability.
Instead of agonizing over word choices all over again in this new resume for a job that involves wood duck nest boxes… I can just pull up these freaking old resumes and copy the word choices I agonized over years ago! Boooooom.

the waitomo caves of new zealand’s northern island, formed two million years ago from the surrounding limestone bedrock, are home to an endemic species of bioluminescent fungus gnat (arachnocampa luminosa, or glow worm fly) who in their larval stage produce silk threads from which to hang and, using a blue light emitted from a modified excretory organ in their tails, lure in prey who then become ensnared in sticky droplets of mucus.

sssscomic:

——>And here’s a link to the print drive page if the image linking didn’t work. Because I still don’t understand how to do anything properly on Tumblr, arggh!<——

That’s riiight!

SSSS is almost a year old and it’s book 1 time! I’m sure you all know how these webcomic crowdfunding campaigns work, but still: it’s basically a fancy, fun, month-long preorder for the book.

I’m really thankful if you guys help spreading the word! The reason I’ve been able to work on the comic full time this year is because my previous comic print drive did so well, and if enough folks get this book I should be able to keep on going and updating as frequently next year too. :3

Read “Stand Still. Stay Silent” over here.

Boosting this! “Stand Still, Stay Silent" is one of my favorite webcomics right now. Gorgeous art, an intriguing world, regular updates, and kitties!

Even if you’re not interested in joining the print drive, I encourage you to check the comic out. And I can vouch for the drive itself and the quality of work that turns out as I participated in the drive for Minna’s previous comic, “A Redtail’s Dream”. The end product arrived on schedule and is a beautiful hardback that makes me smile every time I see it on my shelf.

Finished my curtains last night!

They’re way more washer friendly than the previous curtains so it should be a lot easier to keep the cat fur under control.
They’re also shorter and hang just below the sill, rather than dragging across various desk surfaces, and they’re not nearly as wide so they don’t bunch up at the ends even when closed.

Bonus: they block out way more light than expected but that’s good and should cut down on glare on various screens.

I killed so many spools of thread in this project. I didn’t buy any, just relied on whatever we have in these various boxes and it was juuuust enough and now that’s 6 less spools of tan-ish thread of unknown age or origin taking up space!
