What Does PLSS Stand For?
PLSS stands for Primary Life SuPport Subsystem
The Primary Life Support Subsystem (PLSS) is a vital component of space missions, designed to provide essential life support functions for astronauts. This subsystem manages environmental controls, including oxygen supply, carbon dioxide removal, temperature regulation, and humidity control, ensuring a safe and habitable atmosphere within spacecraft and spacesuits. The PLSS is critical for sustaining life during extravehicular activities and plays a fundamental role in mission success.
