Skylab Extravehicular Activity

Proceedings of the Human Factors Society Annual Meeting, 1974
The use of extravehicular activity (EVA) techniques during Skylab for accomplishing major mission objectives and major and minor repair work outside the Skylab workshop is discussed. The basic feasibility of EVA was demonstrated during the Gemini Program.

Extravehicular activity space suit interoperability

Acta Astronautica, 1995
The European Agency (ESA) and the Russian Space Agency (RKA) are jointly developing a new space suit system for improved extravehicular activity (EVA) capabilities in support of the MIR Space Station Programme, the EVA Suit 2000. Recent national policy agreements between the U.S.

Extravehicular Activity Technology Needs

AIAA SPACE 2010 Conference & Exposition, 2010
Extravehicular activities (EVAs) are an essential component of human space flight. Crewmembers wearing spacesuits have planted flags on the surface of the Moon, inspected the Space Shuttle’s thermal protection system, built the International Space Station, captured satellites, repaired the Hubble Space Telescope, and performed many other critical jobs.

A new preoxygenation procedure for extravehicular activity (EVA)

Acta Astronautica, 1998
A 10.2 psi staged-decompression schedule or a 4-hour preoxygenation at 14.7 psi is required prior to extravehicular activity (EVA) to reduce decompression sickness (DCS) risk. Results of recent research at the Air Force Research Laboratory (AFRL) showed that a 1-hour resting preoxygenation followed by a 4-hour, 4.3 psi exposure resulted in 77% DCS risk

A wearable computer for support of astronaut extravehicular activity

Proceedings. Sixth International Symposium on Wearable Computers,, 2003
A wearable situational awareness terminal (WearSAT) that provides text, graphics, and video to an astronaut via a near-eye display, and acts as a client on a wireless network, has the potential to enhance the ability of astronauts to perform useful work and cope with uncertainty during extravehicular activity (EVA).

Extravehicular activity training and hardware design consideration

Acta Astronautica, 1995
Preparing astronauts to perform the many complex extravehicular activity (EVA) tasks required to assemble and maintain Space Station will be accomplished through training simulations in a variety of facilities. The adequacy of this training is dependent on a thorough understanding of the task to be performed, the environment in which the task will be ...

Automated tether management system for extravehicular activities

Journal of Field Robotics, 2007
AbstractSafe extravehicular activity (EVA) requires astronauts to employ tethers to ensure proximity to their spacecraft. This research strives to improve EVA efficiency by allowing crew members to remotely release and retract their safety tether from extended distances using a tether management system consisting of a remotely releasable robotic ...

Technology of Extravehicular Activity

2020
Extravehicular activity refers to the mission that astronauts use extravehicular spacesuits to leave the pressurized module of a spacecraft, walk outside the spacecraft or on the planetary surface and carry out the relevant operations. In order to meet the requirements of long-term on-orbit safe and reliable operation, the space station must have the ...

Medical Aspects of Extravehicular Activity

2019
Extravehicular activity (EVA), commonly referred to as spacewalks, is an exciting and necessary capability of human space flight. EVA is defined as work performed outside of the pressurized habitable environment of the space vehicle. EVA requires a self-contained living environment provided by a complex pressurized spacesuit.
