The current space suit is made out of four main components.
1.) Liquid Cooling Ventilation Garment (LCVG)
The LCVG has 300 feet of 1/8” dia. tubing woven into a stretchy spandex that comfortably hugs the body and carries the heat away to the backpack where the heat is removed and the cool water recirculated.
2.) Bladder or Pressure Retention Area
This holds the oxygen inside the suit.
3.) Restraint Layer
The restraint layer holds the shape of the suit when pressurized and allows for the flexibility of all body joint when under pressure.
4.) Thermal Micrometeoroid Garment (TMG)
This absorbs impacts from small particles traveling at upwards of 30,000 MPH. It also reflects solar and cosmic radiation and resists heat transferring through the layers.
Since the beginning of our existence, man has wondered how to explain the world around him. This desire for a deeper understanding led to science, which may not have all the answers, but has led humanity to reach these great heights.
1.) Longer Lifespan
Modern medicine and the technology that encompasses its field is truly amazing. If the average lifespan keeps growing at this rate imagine how much it will increase in just 50 years!
Humanity started as an extremely violent race, with tribes killing or enslaving whoever they could. Over time, humans have evolved to live with one another in a much more peaceful setting. While it seems that violent hatred will always exist, science is neither good or evil. It simply depends on the hands of the user, and in the right hands, a weapon can protect the innocent from the disruptor.
3.) Easy Communication

From cell phones to the internet to UAVs, science has made talking to someone on the other side of the globe possible in seconds. We are all connected like never before in a whole new world of communication.
4.) Exploring Man’s Final Frontier: Space
Who hasn’t looked at the stars and wondered what was beyond this world? Now we have the luxury of exploring space through telescopes, robots, and even stepping foot on the moon! This knowledge leads to a a whole new deeper level of understanding how this universe came to be that, frankly, humans just didn’t have 100 years ago.
5.) Provoked Curiosity

The most exciting aspect of science is that every answers seems to lead to 100 more questions. As humankind discovers this world together, we are left wanting to know more. Let science fuel your curiosity and you could create the next great benefit.
Science has provided several benefits to society that could not all be covered here. Feel free to comment and share one of your favorite benefits!”
For today’s fun fact Friday, does anybody know how many stars are hypothesized to be in the sky? If so, what can you think of on Earth that there is more prevalent?
Thanks to NASA/ESA for this beautiful picture of stars forming in the Large Magellanic Cloud.
For today’s fun fact Friday, can anyone tell me what celestial bodies in space we’re made from?
We wanted to have a little fun this weekend and see what type of show our space fans prefer. Would you rather watch Sci-Fi, like Star Trek, or a science-savvy comedy, like Big Bang Theory?
Singapore has built 18 synthetic supertrees, which each have about 200 different types of plants inside. Solar panels scale the trees, allowing sunlight to be easily stored, while their shape acts as thermal storage systems.

Many argue that technology, such as cars consuming oil, are destroying the natural world we live in. Supertrees are just one example that prove technology can be used for the betterment of society. Science and technology neutral, but the hands of the beholder choose where to direct its power.
NASA has detected that there aren’t any aliens running around, but Martian snow does exist. Mars’ South Pole is home to dry ice, which is frozen carbon dioxide, approximately the size of human red blood cell. This discovery is not actually from Curiosity, rather the Mars Reconnaissance Orbiter, which watches the planet from above.
Mars is currently the only planet in our solar system known to have cardon dioxide snowflakes, however this discovery proves the worth of research in our space program. If we looked at our other neighbor planets as in depth as we looked at Mars, who knows what else we could find and learn?
Since my last blog post on the space-time continuum and its implication on traveling into the future, I have been questioned on the reality of traveling back in time. In this post I will be looking at varying time travel theories that exist to eliminate paradoxes.

Say someone does go back in time, only to meet themselves in the past, and they hand their past selves a key to a door. The past self then uses that key to open the door. This means that, in the past, that person received a key from their future self to open that door. A loop in time is created in this example, but let’s go even deeper: what if the future self changed the past?
A paradox. Thanks to byrdseed for the picture.
One theory suggests that for every decision we choose, there exists another dimension where the opposite choice is the reality. This implies that there would be an infinite amount of dimensions in a multiverse, where our universe seems even more minuscule. It also cures any paradox. If that future person changed something in the past, there is already a dimension where this reality exists. Therefore, this theory suggests that the time traveler wouldn’t just be traveling through time, but dimensions as well, to alleviate any paradox.
