GAO Report: NASA: Assessments of Major Projects, GAO
"The National Aeronautics and Space Administration's (NASA) portfolio of major projects continued to experience significant cost and schedule growth this year and the performance is expected to worsen. Since GAO last reported on the portfolio in May 2019, cost growth was approximately 31 percent over project baselines--the third consecutive year that cost growth has worsened after a period of decline. The average launch delay was 12 months, compared to 13 months last year.
Additional cost growth and schedule delays are likely after NASA establishes a new launch date for Artemis I--an uncrewed test flight of the Space Launch System, Orion crew capsule, and associated ground systems. Further, in 2019, GAO found that the Space Launch System (SLS) and Orion programs have underreported cost growth. GAO recommended that SLS calculate cost growth based on costs that are currently included in the first mission and that the Orion program update its cost estimate to reflect the schedule agreed to in its baseline. Both recommendations still require action to address. Looking ahead, NASA will continue to face significant cost and schedule risks as it undertakes complex efforts to return to the moon under an aggressive time frame."
