A Universal Space Suit Concept for Mars Mission

The paper presents a conceptual study of a universal space suit (SS) applicable for Mars manned missions. The following scenario of the suit application is reviewed:

• EVA capabilities in the interplanetary flight phase and in the Mars orbital phase;
• EVA on the surface of Mars;
• suited mode during descent/ascent and rendezvous.

The paper reviews various cases and conditions for EVA periods and requirements they impose on the suit design. Design concepts are selected with high reliability, availability, safety, maintainability and adaptability as principal considerations.
