The first full-pressure suits for use at extreme altitudes were designed by individual inventors as early as the 1930s. The first space suit worn by a human in space was the Soviet SK-1 suit worn by Yuri Gagarin in 1961. Since then space suits have been worn beside in Earth orbit, en-route and on the surface of the Moon.
The suits are white to reflect heat and to stand out against the blackness of space; the red stripes serve to differentiate astronauts. The Extravehicular Mobility Unit ( EMU ) is an independent anthropomorphic spacesuit that provides environmental protection, mobility, life support, and communications for astronauts performing extravehicular ...
NASA planners invented the term extravehicular activity (abbreviated with the acronym EVA) in the early 1960s for the Apollo program to land humans on the Moon, because the astronauts would leave the spacecraft to collect lunar material samples and deploy scientific experiments.
The Apollo/Skylab space suit (sometimes called the Apollo 11 Spacesuit because it was most known for being used in the Apollo 11 Mission) is a class of space suits used in Apollo and Skylab missions. The names for both the Apollo and Skylab space suits were Extravehicular Mobility Unit (EMU). [ 2 ]
SAFER is fitted around the life support backpack of the space suit (EMU or Extravehicular Mobility Unit).SAFER in no way interferes with suit mobility. The flight test unit was fitted with a single hand control module rigidly attached to the Display and Control Module (DCM) in front of the suit.
Along with a NASA designed life support system, the new higher pressure Z suits allow for bypassing pre-breathe and allows for quick donning of the suit and exit of the space craft. The Z-1 is the first suit to be successfully integrated into a suitport dock mechanism eliminating the need for an air lock, and reducing the consumable demands on ...

A portable life support system from the Apollo A7L suit, with its outer cover removed. A primary (or portable or personal) life support system (or subsystem) (PLSS), is a device connected to an astronaut or cosmonaut's spacesuit, which allows extra-vehicular activity with maximum freedom, independent of a spacecraft's life support system.
