What Does PLSS Stand For?
PLSS stands for Portable Life Support Subsystem
The Portable Life Support Subsystem (PLSS) is a compact, self-contained system designed to provide essential life support functions for astronauts during extravehicular activities (spacewalks) or in other hostile environments. It includes critical components such as oxygen supply, carbon dioxide removal, temperature control, and power management, ensuring the safety and well-being of users while enabling mobility and functionality in space. The PLSS is a vital part of space exploration equipment, facilitating extended missions beyond the confines of spacecraft.
