Space Launch System: Cost Transparency Needed to Monitor Program Affordability

Excerpt:  “Last year, NASA launched its Artemis I flight test using a Space Launch System rocket, or SLS. NASA plans to spend billions of dollars to produce more rockets. It also needs to build progressively stronger versions of these rockets for use on Artemis missions into the 2030s. Original SLS cost baselines, or committed costs, were tied to the launch of Artemis I. Without a baseline to track these production costs for upcoming missions, future program costs are less transparent and harder for NASA and Congress to monitor. NASA should act on our prior recommendations to improve transparency and monitoring of this program.”
