Habitation and Logistics Outpost

The Habitation and Logistics Outpost (HALO), (formerly known as Minimal Habitation Module and Utilization Module) is a now canceled module that was planned to be part of the Lunar Gateway. It was built by Northrop Grumman. A Falcon Heavy rocket was planned to launch HALO, already attached to the Power and Propulsion Element in 2027. The NASA Office of Inspector General (OIG) reported that, at cancellation, NASA had spent nearly $1.9 billion on HALO (up from the $1.3 billion contract value), with delivery projected for October 2026, beyond the original May 2025 commitment. However, the OIG further reported that corrosion found in HALO's primary structure would likely have delayed delivery to July 2031.
