1. Space suite description
By: Bryson Core

2. What is a space suits purpose?
A space suit has many purposes Other than giving a astronaut oxygen in outer space. The suit protects them from the harsh temperature in outer space by keeping them from getting too hot or cold. Of course the space suit gives the astronaut oxygen for them to breath but it also protects them from dust particles that are going faster than gun bullets. Space Suits give astronauts water while they are in the suit and the suit has a yellow sun visor that protects their eyes from the sun’s rays. With this information we can conclude that the space suits main purpose is to protect the astronaut.

3. Primary life suport system (PLSS)
A space suit has many parts that make the suit function. For example the primary life support system (PLSS) is worn like a backpack and provides oxygen for the astronaut. It also removes the carbon dioxide that the astronaut breathes out. The PLSS runs on a electrical battery. PLSS holds water cooling equipment to cool off the astronaut and a fan to circulate oxygen. It also has a radio so that the astronaut can contact mission control.

4. The upper torso is made up of the HUT
The upper torso is made up of the HUT. The HUT is made of a hard fiberglass material that is used in cars and pools. This is because the HUT is used for protection as well as carrying tools. It is also the connection piece for tubes that drain water and allow oxygen to flow through the suit.

5. The space suit arms are not custom made but astronauts can get different part sizes. EVA gloves are the gloves astronauts wear in space to pick up objects. They are made to protect astronauts hand and are made to let the astronauts move their fingers as easy as possible. Since the fingers are the easiest part of the body to freeze in space the glove has heated finger tips to keep their fingers from freezing. A piece of the glove called bearing connects the sleeve to the glove and allows the wrist to turn.

6. Display and control module
The display and control module is located on the front of the suit so that the astronaut can control a mini-spacecraft. The astronaut can control the primary life support system (PLSS) with this machine.

7. Wrist mirror and chuff checklist
The astronaut can not see the front of the display and control module with the suit on. This is why they wear the wrist mirror to see the front of the display and control module. Looking at the module with the mirrow makes the words backwards but "backwards" is "forwards."
The chuff checklist is not as impressive. It is a checklist of tasks to do on the astronut's wrist.

8. A plastic bag inside the suit is filled with water and is attached to the upper torso using velcro. A plastic tube comes out the bag of water and is adjusted near the astronauts's mouth. When the astronaut bites the tube a value opens releasing water into the astronaut's mouth. When the astronaut quits biting the value closes.

9. This is also known as the pants, boots and anything from the waist down closure. The waist baring is the part of the waist that helps the astronaut move their legs. A metal piece in the lower torso is what connects it to the upper torso. The lower torso has D-rings that has tethers attacted to them. Then they attach the tethers to the spacecraft so the astronauts will not float into space. The astronauts have different colored lower torsos like white and red and white strips (like candy canes) to tell each astronaut apart

10. The helmet obviously covers and protects the head
The helmet obviously covers and protects the head. It has many other uses for astronauts. The helmet also has a vent pad. This vent pad directs oxygen from the primary life subsystem to the front of the helmet. The helmet is mostly made of a clear plasstic bubble. This bubble is covered by a extravehicular visor assembly. This visor is covered by a thin gold layer that filters out the sun's harmful rays. The visor also protects the person from small objects that may hit it and from extreme temperatures. TV camera and lights maybe attacted to the helmet.

11. Communications carrier Assembly (CCA)
The communications carrier assembly is called the CCA or snooby cab. The astronaut wears a cap under the helmet and has earphones and microphones. They use this cap to connect the astronaut to the radio. Using this the astronauts can communicate with the other astronauts and the hear warning sounds.

12. Liquid cooling and ventilation System
This garment is like underwear expect it cools down the astronaut instead of keeping them warm. It is a stretchy material and has 91.5 meters or 300 feet narrow tubes through out this system. The tubes are pumped with cold water. The cold water runs through the tubes near the skin through out the whole body. By doing this the cold water removes excess heat in the suit. The vents in the system removes the sweat and recycles the sweat through the water cooling system.

13. SAFER is like a life jacket except in space
SAFER is like a life jacket except in space. SAFER is what astronauts wear like a backpack when they are outside the space station. The astronauts wear a tether that is connected to the spacestation if the tether breaks lose from the station instead of floating away they control the SAFER to bring them back to the spacestation (like a jetpack). The SAFER uses small nitrogen jet thrusters to let the astronaut move around in space. They use a joystick to control it.

14. The space suit has 14 layers to protect the astronaut
The space suit has 14 layers to protect the astronaut. The first 3 layers are cooling and ventalation material. Next is the bladder layer. It puts the right about of pressure on the body and holds the oxygen to breath. The next layer holds the bladder layer in the correct shape around the astronauts's body and is the same material as camping tents. The tear resistance layer is the ripstop linear. The next 7 layers are Mylar insulation. This makes the suit thermos. The outer layer is made up of 3 materials. One is waterproof. The second is a bullet-proof vest. The last is fire proof.

15. To answer Mrs. Wilson's question about how do astronauts go to the bathroom, they do not. Instead they wear adult diapers. Most of the time when the astronauts do a spacewalk it typically last more than 6 hours so instead of going to the bathroom they wear adult diapers.

16. I liked doing this project but like all projects it takes up my time
I liked doing this project but like all projects it takes up my time. I do not like the fact that projects take up so much time. As far as this project goes it was interesting to find out how a space suit worked. That is why I chose this topic to learn something new. I really like the fact that our teacher let us choose our topic instead of giving us topics to do. I have not had many teachers who let me choose my project. This maybe the reason I do not like projects.
