0.000 HBDSpaceX Spacesuit: Style Without Functionality?
<center> </center> Today Elon Musk has published the first picture of SpaceX spacesuit. According to his statement is not a model but a working sample that passed the first tests. As Max writes, it was quite difficult to strike a balance between aesthetics and functionality. No doubt, it looks very cool. But there is no information about what functionality can provide this costume, and whether it can rightly be called a spacesuit. <center> </center> Let's be objective: even with the leadership of SpaceX and other Mask's companies in many advanced technologies, it's hard to believe that this suit has everything necessary for survival in space. #### A space suit should provide protection from the following basic threats: the absence of oxygen, high and low temperature, pressure compensation, radiation and solar wind. <p> Let's compare this trendy outfit with the most «powerful» NASA's suit: EMU, which is used for work in outer space. <center> EMU suit (<a href="https://www.google.ru/search?newwindow=1&biw=1440&bih=761&tbm=isch&sa=1&q=emu+space+suit&oq=EMU+space&gs_l=psy-ab.1.0.0i30k1j0i24k1l2.870.2131.0.3703.6.6.0.0.0.0.70.348.6.6.0....0...1.1.64.psy-ab..0.6.345...0j0i2k1j0i19k1j0i8i30i19k1.HFS-TlgJw2Y#imgrc=36P2tdACqD9QKM:">images</a>)</center> EMU combines soft and hard materials, which provides protection and mobility. In fact, the material of the suit consists of 13 layers: two layers of internal cooling, two layers of compressing, eight layers of thermal and micrometeorites protection and one outer layer. The composition of these layers is composed of the following materials: knitted nylon, spandex, urethane nylon, dacron neoprene, nylon, mylar, gortex, kevlar and nomex. EMU consists of different functional modules: * MAG (collects urine), * LCVG (removes excess heat), * EEH (provides communication), LTA (lower part of the suit, pants, knee pads, Shin guards and boots), * HUT (upper part of the costume, hard fiberglass shell that supports several structures: arms, torso, helmet, life support backpack and control module), * PLSS (primary life support system: oxygen, energy, carbon dioxide cleaning, cooling, water). And that's not all, a complete description of the parts of the costume you can see in the picture below: <center>  you can find a detailed description and more images <a href="http://orbiterchspacenews.blogspot.ru/2012/01/spacesuits-nasa.html">HERE</a> </center> #### EMU is designed for 8 hours of work in outer space and withstand the temperature range from -184 °с to +149 °с degrees, this monster weighs 145 kg. The production cost of one suit ranges from 12-20 million dollars. Hom much will cost SpaceX suit?- We don't know. <p> A couple of years ago, NASA launched the development of a new prototype Z1 (Buzz Lightyear suit). But, it was too bulky and uncomfortable. Therefore, almost immediately was started work on the next prototype Z2. <center>  <a href="https://www.nasa.gov/feature/the-next-generation-of-suit-technologies">Source NASA</a>. *The most curious can see how the <a href="https://www.google.ru/search?q=nasa+z1&newwindow=1&source=lnms&tbm=isch&sa=X&ved=0ahUKEwj-14K4vu3VAhWrNpoKHbdNAo0Q_AUICygC&biw=1440&bih=761">Z1 looked</a> :)* </center> In fact, Z2 is the symbiosis of the EMU suit with Dava Newman development- Biosuit. Biosuit is a tightly wrapped fabric of polymers and active materials (alloy of nickel and titanium). <center>  Biosuit. <a href="https://www.wired.com/2014/01/how-a-textbook-from-1882-will-help-nasa-go-to-mars/">Source and more information with pictures</a></center> It is worth noting, that Elon Musk never claimed that the development of SpaceX is able to provide the astronaut with all the necessary functionality. Today, cosmonauts have a wide range of suits that meet completely different requirements and serve for different situations. Can you imagine that Mask's suit replace all these parts: <center> </center> From right to left: *1. Suit for outer space 2. For activity inside a spaceship 3-4. External pressurized suit 5-6. Inner suit pressurized suit 7. Shell with insulation and protection from meteors 8. Suit of constant wearing 9. Suit with liquid cooling 10. NWM :)*. <a href="http://www.furfur.me/furfur/culture/culture/169731-odezhda-buduschego-skafandry">source</a></center> <p> #### Most likely, the model of SpaceX is intended primarily for the environment, which already has a primary basic protection from space impacts: on board the spacecraft, space rover, station of colonists on another planet. <p> The main objective of this suit is to protect the astronaut from the low temperature differential and a short-term lack of oxygen. This suit can give a few minutes of life, that could be decisive in a critical situation, and will allow the cosmonaut to reach the rescue compartments or a more reliable spacesuit. #### <center>I look forward to more detailed presentations...</center> <center><a href="https://steemit.com/@natord"> </a></center>
