Is a space suit made of leather?

Answer 1

David Bragg, of Carlisle, England asked the following question of Tony Ceccacci, flight director for the orbit 2 team

Question: What materials are spacesuits made of?

Answer: David: We call the spacesuit an EMU, which stands for extravehicular mobility unit. The EMU consists of a hard upper torso, a lower torso assembly, gloves, a helmet and visor assembly, communications carrier assembly, liquid cooling and ventilation garment, urine collection device, and an operational bioinstrumentation system. The upper torso, including arms, is that portion of the pressure suit above the waist, excluding the gloves and helmet. It provides the structural mounting for most of the EMU -- helmet, arms, lower torso, portable life support system, display and control module, and electrical harness. The arm assembly contains the shoulder joint and upper arm bearings that permit shoulder mobility as well as the elbow joint and wrist bearing. The basic structure is made of Fiberglas. The lower torso connects to the hard upper torso by a waist ring. It is composed of several layers, beginning with a pressure bladder of urethane-coated nylon, a restraining layer made of Dacron, an outer thermal garment made of neoprene-coated nylon, four layers of aluminized Mylar and a surface layer of Gortex and Nomex.
