Extravehicular activity (EVA) is any activity done by an astronaut in outer space outside a spacecraft. In the absence of a breathable Earthlike atmosphere, the astronaut is completely reliant on a space suit for environmental support. EVA includes spacewalks and lunar or planetary surface exploration (commonly known from 1969 to 1972 as ...
The Z-1 is the first Z prototype suit constructed. The Z series [1] is a series of prototype extra-vehicular activity (EVA) space suits being developed in the Advanced Extravehicular Mobility Unit (AEMU) project under NASA's Advanced Exploration Systems (AES) program.
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 ...
This is a list of the 26 longest spacewalks, also known as an extravehicular activity or EVA. "Agency" here refers to the organization under whose auspices the EVA was conducted (so a Swiss or Japanese astronaut would be listed under NASA if they wore NASA suits and were controlled by Mission Control Houston).
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 ...
The Feitian space suit (Chinese: 飞天航天服; pinyin: Fēitiān Hángtiān Fù) is an extravehicular space suit design developed and used by the China Manned Space Program. It provides life support, environmental protection, and communications for taikonauts during extravehicular activity (EVA).
On the International Space Station (ISS), extravehicular activities are major events in the building and maintaining of the orbital laboratory, [1] and are performed to install new components, re-wire systems, modules, and equipment, and to monitor, install, and retrieve scientific experiments.

Virtual reality has been explored as a technology to artificially expose astronauts to space conditions and procedures prior to going into space. Using virtual reality, astronauts can be trained and evaluated on performing an EVA (extravehicular activity) with all the necessary equipment and environmental features simulated.
