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 ...
Haiying (海鹰号航天服) EVA space suit: The imported Russian Orlan-M EVA suit is called Haiying. Used on Shenzhou 7. Feitian (飞天号航天服) EVA space suit: Indigenously developed Chinese-made EVA space suit also used for the Shenzhou 7 mission. [42] The suit was designed for a spacewalk mission of up to seven hours. [43]
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 ...
In a suitport system, a rear-entry space suit is attached and sealed against the outside of a spacecraft, space habitat, or pressurized rover, facing outward.To begin an extra-vehicular activity (EVA), an astronaut in shirt-sleeves first enters the suit feet-first from inside the pressurized environment, and closes and seals the space suit backpack and the vehicle's hatch (which seals to the ...

In an independent space suit, the heat is ultimately transferred to a thin sheet of ice (formed by a separate feed water source). Due to the extremely low pressure in space, the heated ice sublimates directly to water vapor, which is then vented away from the suit.
Simplified Aid For EVA Rescue (SAFER) is a small, self-contained, propulsive backpack system worn during spacewalks, to be used in case of emergency only. If an untethered astronaut were to lose physical contact with the vessel, it would provide free-flying mobility to return to it.
