The defining challenge of the Moon is not the lack of air, but the presence of dust. Lunar regolith is composed of jagged, glass-like shards that destroyed seals and jammed mechanisms during Apollo.

The E439 suit features a revolutionary "suitport" design and advanced bearing systems specifically engineered to mitigate dust. Unlike previous suits that were donned inside a pressurized spacecraft (dragging dust in with them), the xEMU is designed to attach to the outside of the rover or habitat. Astronauts enter the suit from the back, sealing the spacecraft’s interior from the abrasive lunar environment. The E439 tests in 2021 focused heavily on these pressure seals, ensuring that the "gray plague" would not jeopardize the mission.
