The E.M.U Display and Control Module (DCM). The EMU, like the Apollo/Skylab A7L spacesuit, was the result of 21 years of research and development. [Note 1] It consists of a Space Suit Assembly (SSA) assembly which includes the Hard Upper Torso (HUT), arm sections, gloves, an Apollo-style "bubble" helmet, the Extravehicular Visor Assembly (EVVA), and a soft Lower Torso Assembly (LTA ...
Extravehicular Mobility Unit (EMU) – used on both the Space Shuttle and International Space Station (ISS). The EMU is an independent anthropomorphic system that provides environmental protection, mobility, life support, and communications for a Space Shuttle or ISS crew member to perform an EVA in Earth orbit. Used from 1982 to present, but ...
The Apollo 11 EMU featured an A7L suit with a -6 (dash six) backpack reflecting seven suit and six backpack design iterations. [4] The A7L was a rear entry suit made in two versions. The Extra-vehicular (EV), which would be used on the Moon and the Command Module Pilot (CMP) that was a simpler garment.
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.
When the United States resumed EVAs on April 7, 1983, astronauts started using an Extravehicular Mobility Unit (EMU) for self-contained life support independent of the spacecraft. STS-6 was the first Space Shuttle mission during which a spacewalk was conducted.
The original HUT design for the EMU, first used in 1980, included bellowed shoulder bearings, which allowed for variation in the angle of the shoulder bearings. This allowed for one configuration to ease donning of the suit, and a different configuration to allow maximum mobility during EVA. However, the limited life of the bellows prompted a ...
The I-Suit incorporates improvements in materials and manufacturing techniques which make it both lighter and more mobile than the EMU. While the EMU is solely intended for the microgravity environment, where weight is not an issue, the I-Suit's planetary role makes weight a critical factor. By replacing the EMU's fiberglass Hard Upper Torso (HUT) section with a soft upper torso, or SUT, and ...
