Engineering Analysis

Key Subsystem Architecture

Life support system drawing on Collins Aerospace PLSS heritage; RTX aerospace manufacturing

Mission Role

ISS orbital EVA; received NASA xEVAS task order December 2022; withdrew from task order June 2024

Limitations & Failures

Design specifications not public; withdrew from NASA xEVAS ISS EVA task order June 2024

Program Lesson
"xEVAS dual-award to Axiom Space and Collins Aerospace (2022) demonstrated NASA strategy of maintaining two US EVA suit developers. Collins withdrawal in 2024 reverted ISS EVA suit supply to single-provider risk."
Future Relevance

Collins exit from xEVAS leaves commercial station EVA market (Starlab, Orbital Reef) without a second-source US EVA suit developer under NASA contract.

Documented Failure Cases
Critical 2013

Water entered Luca Parmitano's helmet during EVA — vision impaired, comms degraded, breathing compromised

→ Cooling-water management is a primary safety-critical function, not a nuisance issue. Contamination tolerance must be designed in from day one
