NASA simplifies lunar spacesuits to accelerate Artemis IV mission
NASA has opted to develop a simplified "Sortie Suit" variant of the planned AxEMU lunar spacesuit for the initial Artemis landing missions, aiming to lower mass, reduce complexity, and streamline interfaces with SpaceX and Blue Origin landers.
The move reflects Administrator Jared Isaacman's push to get Artemis back on track for a 2028 crewed landing, with requirements being relaxed — including shorter certification timelines — after the program fell behind schedule and risked ceding the Moon to China.
Axiom Space, now the sole suit provider after Collins Aerospace withdrew, is working closely with NASA six days a week to adapt the design, which had exceeded mass budgets due to demanding original requirements such as six EVAs over 6.5 days and two-hour operation in permanently shadowed regions.
