CONSTANT PRESSURE Causes Strain To astronauts While WEARING A Space Glove
Problem:
Imagine if you were to be part of a long-term space expedition. Eventually, every one of your team members would have to wear a pair of space gloves, in order to complete shuttle repairs or other various repairs. Over time the constant pressure on your fingers would cause strain on your hands. Not only that but your fingernails would start to fall off! This is true due to the 6-8 hours astronauts are out in spacewalks. According to Dava Newman, the MIT director of technology she says astronauts with bigger hands suffer more from this.

Layers of The EVA Gloves
Layers Of The Glove:
In order to understand our project in full you must first understand the three different layers of the space glove. The Outer most layer is the TMG Palm which protects the astronauts from radiation and different temperature conditions out in space. The second layer is the restraint. The restraint is like the mold of the glove. It makes sure the bladder keeps it's form when it is inflated with oxygen. And finally the layer we will be focusing on is the Bladder. The bladder is most likely the most important layer due to its job. The bladder is the inner most layer and is where all the oxygen is kept. Due to the oxygen that builds up in the finger this is why we see astronauts experiencing pain and in some cases even losing finger nails.

Gas Law Equation
Gas Law Relation:
Gas law play a pretty significant role due to the basic concept that when changing volume inside of something the pressure of the gas molecules inside will also change depending on if the volume is increased or decreased. In relation to the space glove if there was a change in volume the change occurs there will also be a change in pressure. This change occurs when the astronauts try to bend their fingers. When the astronauts bend their fingers they cause a change in volume due to the crinkles. When these crinkles occur a pocket of air also known as gores is formed and these pockets of air have a lot of pressure that almost feel like a resistance for the astronaut when trying to bend. These gores are the main cause of discomfort inside of the space glove.
