Artemis II mission, which is scheduled to launch as early as April 1, 2026, here is a detailed explanation of the hyperbaric, compression, and decompression systems, which are primarily managed through advanced spacesuits and spacecraft life support.

🚀 The Primary System: Orion Crew Survival System (OCSS) Suit
The primary technology that manages pressure and protects the crew is the Orion Crew Survival System (OCSS) suit . Unlike the bulky suits used for spacewalks, this is an intravehicular (IVA) suit worn during critical phases like launch, ascent, and re-entry.
· Pressurized Environment ("Hyperbaric" Function): The OCSS suit acts as a "personal spacecraft" . In the event of a cabin depressurization in deep space, the suit can be pressurized to sustain the astronaut's life .
· Emergency Survival Duration: The suit is engineered to keep an astronaut alive for up to six days in an emergency, providing a contained atmosphere, oxygen, hydration, and even waste management .
