NASA's canceled Artemis hardware contracts reached $5.9 billion, audit finds

Key Points:

• NASA's Office of Inspector General (OIG) revealed that major Artemis program hardware, including the Exploration Upper Stage (EUS), Universal Stage Adapter (USA), Mobile Launcher 2 (ML-2), and Gateway's HALO module, became costly components that no longer fit the agency's revised lunar mission plans and have been canceled.
• The canceled hardware, originally contracted at $2.9 billion, reached a final investment of $5.9 billion by the time work ceased, with ongoing development delays, technical issues, and cost overruns contributing to the decision to restructure Artemis and simplify mission architecture.
• Boeing's EUS faced significant delays and cost increases, with delivery pushed from March 2021 to an estimated end of 2028, while Dynetics' USA and Bechtel's ML-2 also experienced substantial budget growth and schedule slippage due to performance and management challenges.
• The HALO module suffered from corrosion issues and unrealistic scheduling pressures, leading to cost growth from $187 million to $1.9 billion and delays extending to 2031 before cancellation amid NASA's shift away from the Gateway space station concept.
• NASA acknowledged the impact of shifting mission requirements, resource shortages, and contractor difficulties but emphasized that the Artemis program restructuring aims to promote discipline, affordability, simplification, and faster lunar return timelines.
