Journal of Purdue Undergraduate Research, 2012 While in microgravity, astronauts are preoccupied with physical restraint, which takes attention away from the maintenance task or scientific experiment at hand. This may directly lead to safety concerns and increased time for extravehicular activity, as

The Importance of a Liquid Cooled Garment for Extravehicular Activity
, 2018 The liquid cooling and ventilation garment (LCGV) is a lifeline for astronauts working in space. Without the use of the LCVG, astronauts would be subject to the extreme temperature swings of the outside environment and inevitably create a hostile ...
