On Wednesday, NASA’s Office of the Inspector General prepared a memorandum on the elements of the Artemis Program that NASA was canceling as its focus shifted to the Moon’s surface. These were:

Exploration Upper Stage, an upgrade for the Space Launch System rocket
Universal Stage Adapter, which links the Orion spacecraft to the Exploration Upper Stage
Mobile Launcher 2, a larger launch tower for the upgraded Space Launch System rocket
Habitation and Logistics Outpost, a habitation module for the Lunar Gateway
The memorandum notes that each of these projects has experienced substantial cost increases and numerous delays over the last decade.

“Over the course of their life cycles, the combined contract values for these efforts ballooned from nearly $2.8 billion to $5.9 billion and NASA extended their contracted delivery dates by up to seven years,” states the report by the inspector general. “However, our projections indicate that if NASA allowed work to continue to completion, the systems would have cost more and taken longer than what was on contract.”
