"Pressurized mobility and re-entry-to-airlock recovery must be a top-level requirement, not an afterthought"
"Rear-entry and semi-rigid architecture remain highly relevant for surface systems and suitport concepts"
"Dedicated EVA architecture dramatically improved work efficiency vs IEVA"
"Europe proved the rear-entry rapid-donning concept works — but without a funded anchor mission the architecture never matured"
"Orbital EVA systems must be treated as maintainable fleets, not isolated suits"
"Long-life EVA programs shift from design problems to sustainment, anomaly and industrial-base problems"
"Pragmatic dual-track approach — import to reduce mission risk while demonstrating domestic capability simultaneously"
"Exploration programs need firm mass control and stable mission assumptions before subsystem elaboration begins"
"Once a suit becomes a fleet asset, lifecycle economics and telemetry matter more than peak performance figures"
"Modern lunar design explicitly built around mobility, fit range and maintainability lessons from legacy systems"
"xEVAS dual-award to Axiom Space and Collins Aerospace (2022) demonstrated NASA strategy of maintaining two US EVA suit developers. Collins w…"
"Lunar suit must be treated as a new architecture branch — not an incremental Feitian derivative — due to dust, terrain and thermal differenc…"
