QUESTION:
What is the space suit made of?

ANSWER from the Internet:
(http://www.jsc.nasa.gov/pao/factsheets/wardrobe.html)
The suit comprises several layers including a polyurethane-coated nylon
pressure bladder, a polyester structural restraint layer with folded and
pleated joints (for mobility), and a woven Kevlar, Teflon, and Dacron
anti-abrasion outer layer.

The EMU comprises the spacesuit assembly, the primary life support system
(PLSS), the display and control module, and several other crew items
designed for spacewalks and emergency life support. The EMU accommodates a
variety of interchangeable systems that interconnect easily and securely in
singlehanded operation for either normal or emergency use. When preparing to
work in space, the astronaut goes into the airlock of the space shuttle
orbiter and puts on the following parts of the EMU:

* A urine-collection device that receives and stores urine for transfer
later to the orbiter waste management system.

* A liquid cooling and ventilation garment, a one-piece mesh suit made of
spandex, zippered for front entry, and weighing 6.5 pounds dry. The garment
has water-cooling tubes running through it to keep the wearer comfortable
during active work periods.

* An in-suit drink bag containing 21 ounces of potable water, the "Snoopy
Cap," or communications carrier assembly, with headphones and microphones
for two-way communications and caution-and-warning tones, and a biomedical
instrumentation subsystem.

To put on the spacesuit, the astronaut first dons the lower torso assembly
and then rises into the top section of the two-piece EMU spacesuit hanging
on the wall of the airlock. The upper torso of the spacesuit is a hard-shell
fiberglass structure that contains the primary life support system and the
display control module. Connections between the two parts must be aligned to
enable circulation of water and gas into the liquid cooling ventilation
garment and return. Then, the gloves are added and last to be donned is the
extravehicular visor and helmet assembly, which provides protection from
micrometeoroids and from solar ultraviolet and infrared radiation. Bearings
in the shoulder, arm, wrist, and waist joints allow the crewmember freedom
of movement. Bending, leaning, and twisting motions of the torso can all be
done with relative ease.

All fabric-to-hardware connections are made with either mechanical joints or
adhesive bonding. Materials used in the construction of the suit are
selected to prevent fungus or bacteria growth; however, the suit must be
cleaned and dried after flight use.

The entire suit assembly is rated with a minimum 8-year life expectancy. The
nominal operating atmospheric pressure in the suit is 4.3 psid.
