Can anyone explain to me IN DETAIL what astronauts were and what are the layers of the suit?

Question

I'm doing a project on Astronauts and what they wear so I need help. Project due tomorrow! GMT! AARRGGGGHHHH!

Answer 1

Try searching for "Space Suit" on www.nasa.gov
I found this... http://history.nasa.gov/spacesuits.pdf
which looks like it may have what you want (Pictures too).
You may find other sources on the NASA site.

Answer 2

A project on astronauts due on Sunday? Are you a Scientologist or something? :)

Anyway, Wikipedia's a great thing:

Answer 3

Materials used to make space suit:

Nylon tricot
Spandex
Urethane-coated Nylon
Dacron
Neoprene-coated Nylon
Mylar
Gortex
Kevlar (material in bullet-proof vests)
Nomex
All of the layers are sewn and cemented together to form the suit. The space suit consists of the following parts:

Maximum Absorption Garment (MAG) – During almost seven hours of space walking, it is difficult for astronauts to relieve themselves of the urine produced by their body For this reason, every astronaut space walking, wears a large, absorbent diaper, which collects urine and feces while in the spacesuit. The MAG is disposed off after the completion of the space walk.
Liquid Cooling and Ventilation Garment (LCVG) – LCVG is a set of Nylon tricot and spandex "long underwear" that is laced with thin plastic tubes through which, cool water flows which eliminates the excess body heat produced by the astronaut. The cooling water comes from the spacesuit's backpack unit or from the spacecraft through an umbilical cord.
EMU Electrical Harness (EEH) - This is a set of communications wires and bio instruments worn by the astronaut inside the suit. It connects to the radio and bio instruments in the suit's backpack. It helps in communication and monitors the astronaut's vital signs such as respiration rate, heart rate, temperature, etc.
Communications Carrier Assembly (CCA) - The CCA is a fabric cap worn by the astronaut, which contains microphones and earphones enabling hand-free communication with the radio.
Lower Torso Assembly (LTA) - The LTA is a single unit, which includes pants, knee and ankle joints, boots and lower waist. A metal connect ring facilitates its fitting.The LTA has loops to join the tools preventing them from floating away in space.
Hard Upper Torso (HUT) - The HUT is a hard fiberglass shell that resembles a vest and supports numerous structures such as the arms, lower torso, helmet, life-support backpack and control module.
Arms - Arm unit holds shoulder, upper arm and elbow joint bearings enabling the astronaut free movement of his arms in any direction. The arm units are of various sizes so that they can be fitted to different astronauts.
Gloves - Gloves aid easy movement of the wrist bearings. They are attached to the arms by quick-connect rings. For a proper grip on things, gloves have rubberized fingertips. Astronauts also wear fine-fabric gloves inside the outer glove units for comfort. The outer gloves have loops on them to tether tools.
Helmet - The helmet is made of clear, impact-resistant, polycarbonate plastic, and is attached to the HUT by a quick-connect ring. The helmet is padded in the rear for comfort; it has a purge valve to eliminate carbon dioxide if the backup oxygen supply has to be used. In the helmet, oxygen flows from behind the astronaut's head, over the head and down his or her face. The inside of the helmet is treated with an anti-fog compound before the space walk
Extravehicular Visor Assembly ( EVA) – It protects the astronaut from bright sunlight.
In-suit Drink Bag (IDB) – It provides drinking water to the astronaut during the space walk. It is a plastic pouch placed inside the HUT and can hold 32 ounces (1.9 liters) of water and has a small tube something like a straw that is placed next to the astronaut's mouth.
Primary Life Support Subsystem (PLSS) – The PLSS is the backpack worn by the astronaut. It contains oxygen tanks, carbon dioxide scrubbers/filters, cooling water, radio, electrical power, ventilating fans and warning systems
Secondary Oxygen Pack (SOP) – It provides emergency oxygen supply and fits below the PLSS on the backpack frame
Display and Control Module (DCM) - The DCM is a chest-mounted unit. It holds all the switches, gauges, valves and LCD displays essential for operating the PLSS. The astronaut, with the help of a sleeve-mounted mirror, can view the DCM.
