American space suit, tested 1964-68. Between 1964 and 1968 two hard suit assemblies were developed at NASA-ARC, identified as the AX-1 (Ames Experimental) and AX-2. These suits were the first to demonstrate multiple bearing technology.
The AX-3 was an 0.5 bar suit, 23 kg, 0.5 to 0.7 bar operational pressure, with improved mobility and was completed in 1977. The program culminated in the development of the prototype AX-5, an all hard suit for high pressure application and zero prebreathe in the 1980's. The AX-5 shared common design goals with the ILC Mark III. For example, they had to be easy to get into and out of, be comfortable to wear, and allow adequate mobility and range of motion for the jobs to be performed. Both were designed to be altered to fit different size astronauts
Gross mass: 23 kg (50 lb).

Space Suits To explore and work in space, human beings must take their environment with them because there is no atmospheric pressure and no oxygen to sustain life. Inside the spacecraft, the atmosphere can be controlled so that special clothing is not needed. But in order to work outside the spacecraft, humans need the protection of a spacesuit. More...
