Background

The Habitation and Logistics Outpost (HALO) was designed as the first crewed module of the Lunar Gateway, built by Northrop Grumman. The module had already arrived at the launch preparation facility when the Gateway programme was cancelled in 2026, leaving it with no deployment path.

HALO was conceived as a node module providing crew quarters, communications and docking for visiting vehicles including the Human Landing System. Its cancellation represents a sunk cost of several hundred million dollars in completed hardware.

The module's fate is emblematic of the wider Gateway cancellation: hardware exists but has nowhere to go. NASA has not announced a repurposing plan, and the political momentum that sustained Gateway through multiple administrations has definitively ended.
