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."

Terraformation of Mars: A New Look
We look at Mars now as a forgotten Red Planet that almost seems barren and life-less judging from our available images and study of it. But study shows Mars was once as ecologically prosperous as our own Earth. But what happened to all of its waters? Better yet why is it so dry and lacking any plants? Once the abundance of oxygen left and the waters froze over or dried off the planet became what it is today. But what if we can in a way reactivate’ Mars? Welcome to Mars, Terraformed’.
About Terraforming
Transforming Mars will be a long and complicated process. But this is exactly the type of subject that interests space researchers like Christopher McKay of NASA Ames Research Center. First, greenhouse gases, like chlorofluorocarbons that contribute to the growing ozone layer on Earth, will be released into the atmosphere. This traps the heat from the Sun and raises the surface temperature by an average of 4 degrees Celsius. In order to achieve this, factories would manufacture chlorofluorocarbons derived from the air and soil. A single factory would require the power equivalent of a large nuclear power plant.
The increasing temperature would vaporize some of the carbon dioxide in the south polar cap. Introducing carbon dioxide into the atmosphere would produce additional warming, melting more of the polar cap until it has been vaporized completely. This would produce an average temperature rise of 70 degrees Celsius.
With the temperature this high, ice will start melting, providing the water needed to sustain life. This water would raise the atmospheric pressure to the equivalent of some mountaintops. While this would be a survivable level, it may still require the use of an oxygen mask. The next step, which may take up to several centuries, would be to plant trees that thrive on carbon dioxide and produce oxygen.

NASA: Terraforming Mars
Terraforming is the process of transforming a hostile environment into one suitable for human life. Being that Mars is the most Earth-like planet, it is the best candidate for terraforming. Once just the subject of science fiction novels, it is now becoming a viable research area. The famed astronomer and Pulitzer prize winner, Carl Sagan, says that there is enormous promise in the search for ancient life on Mars. If life was once sustainable on Mars, it is important to know what caused Mars to evolve into the cold and lifeless planet it is today. With this knowledge, we can terraform Mars by reversing the process.
NASA scientists believe that it is technologically possible at the present time to create considerable global climate changes, allowing humans to live on Mars. But this will not be by any means an easy task. Raising the atmospheric pressure and surface temperature alone could be achieved in a few decades.
This research has strong environmental implications for Earth. What researchers are trying to do involves global warming, a sort of greenhouse effect on the cold planet Mars. Scientists may be able to test their hypotheses about global warming in their attempts to elevate Mars’ surface temperature. Likewise, once theories, they may be applied to our own planet in an attempt to reverse environmental damage done by pollution and deforestation.

In 1972 NASA launched the "Jupiter Plaque", an engraved tablet depicting life on Earth and our location in the cosmos, for any intelligent life that may come across it.
The Los Angles Times asked several prominent artists to draw what they would have put on the plaque and why. To the surprise of everyone, Kirby the futurist and visionary drew two superbeings, a man and a woman, that would scare away potential conquerors. Suggesting to intelligent life that everyone on Earth are Supermen. This was his explanation:
"I see no wisdom in the eagerness to be found and approached by any intelligence with the ability to accomplish it from any sector of space. In the meetings between ‘discoverers’ and ‘discoverees’, history has always given the advantage to the finders. In the case of the Jupiter Plaque, I feel that a tremendous issue was thoughtlessly taken out of the world forum by a few individuals who have marked a clear trail to our door. My point is who will come-a-knocking, the trader or the tiger?"

It’s scary how much sense this makes.

Sept. 12, 1992: Dr. Mae Jemison Becomes First African American Woman in Space

On this day in 1992, Dr. Mae Jemison became the first African American woman to travel through space. She served as Mission Specialist aboard Space Shuttle Endeavour on STS-47.

WTCI’s Alison Lebovitz discusses the legacy of the first woman of color to travel beyond the stratosphere on “The A List with Alison Lebovitz.” Watch the interview here.

Photos: NASA

Jemison appeared on Wait Wait Don’t Tell Me in 2013 and told host Peter Sagal how she geeked out about Star Trek as a young woman, relished dancing in the Space Shuttle Endeavour, abhorred using diapers in space, and much more.

She also described what it felt like to finally achieve her dream of visiting space:

And I remember one time actually we flew through the Southern Lights… They’re these shimmering curtain of lights. So there’s nothing that you could have ever seen in a science fiction movie that would even come close to seeing that in person.

Pretty stellar.
