Audit Calls NASA’s Goal To Reduce Artemis Rocket Costs ‘Highly Unrealistic,’ Threat To Deep Space Exploration – Slashdot | CPT PPP Coverage

Richard Tribou reports via Phys.Org: NASA’s goal to reduce the costs of the powerful Space Launch System rocket for its Artemis program by 50% was called “highly unrealistic” and a threat to its deep space exploration plans, according to a report by NASA’s Office of the Inspector General released (PDF) on Thursday. The audit says the costs to produce one SLS rocket through its proposed fixed-cost contract will still top $2.5 billion, even though NASA thinks it can shrink that through “workforce reductions, manufacturing and contracting efficiencies, and expanding the SLS’s user base.”

“Given the enormous costs of the Artemis campaign, failure to achieve substantial savings will significantly hinder the sustainability of NASA’s deep space human exploration efforts,” the report warns. The audit looked at NASA’s plans to shift from its current setup among multiple suppliers for the hardware to a sole-sourced services contract that would include the production, systems integration and launch of at least five SLS flights beginning with Artemis V currently slated for as early as 2029. NASA’s claim it could get those costs to $1.25 billion per rocket was taken to task by the audit.

“NASA’s aspirational goal to achieve a cost savings of 50% is highly unrealistic. Specifically, our review determined that cost saving initiatives in several SLS production contracts were not significant,” the audit reads. It does find that rocket costs could approach $2 billion through the first 10 SLS rockets under the new contract, a reduction of 20%. […] Through 2025, the audit stated its Artemis missions will have topped $93 billion, which includes billions more than originally announced in 2012 as years of delays and cost increases plagued the leadup to Artemis I. The SLS rocket represents 26% of that cost to the tune of $23.8 billion. The inspector general makes several recommendations to NASA. The most striking of which is that NASA consider using commercial heavy-lift rockets, such as SpaceX’s Starship and Super Heavy or Blue Origin’s New Glenn, as an alternative to the SLS rocket for future Artemis missions.

“Although the SLS is the only launch vehicle currently available that meets Artemis mission needs, in the next 3 to 5 years other human-rated commercial alternatives that are lighter, cheaper, and reusable may become available,” the audit reads. “Therefore, NASA may want to consider whether other commercial options should be a part of its mid- to long-term plans to support its ambitious space exploration goals.”
