INTRO: In a new report(PDF), the federal department charged with analyzing how efficiently US taxpayer dollars are spent, the Government Accountability Office, says NASA lacks transparency on the true costs of its Space Launch System rocket program.
Published on Thursday, the new report (see .pdf) examines the billions of dollars spent by NASA on the development of the massive rocket, which made a successful debut launch in late 2022 with the Artemis I mission. Surprisingly, as part of the reporting process, NASA officials admitted the rocket was too expensive to support its lunar exploration efforts as part of the Artemis program.
"Senior NASA officials told GAO that at current cost levels, the SLS program is unaffordable," the new report states.
The Government Accountability Office expressed serious concerns about NASA's decision not to measure production costs of SLS rocket elements, including the core stages and rocket engines needed for future launches. Instead, NASA told the report authors that it plans to "monitor production costs and affordability of the SLS program via the five-year production and operations cost estimate."
However, the report states, these are "poor tools" for a cost baseline for the SLS rocket program and will make it difficult for taxpayers to measure costs and the performance of NASA and its contractors over time. Moreover, the report indicates that NASA has not regularly updated its five-year production cost estimates for the rocket. The report also cites concerns about development costs of future hardware for NASA's big-ticket rocket program, including the Exploration Upper Stage.
Another problem with NASA's cost estimates is that they do not appear to account for delays to Artemis missions. It is probable that the Artemis II mission, a crewed flight around the Moon, will launch no earlier than 2025. The Artemis III crewed landing will likely slip to at least 2026, if not more, with additional delays down the line. At least one NASA official apparently told the Government Accountability Office that these delays would have no cost impacts, which seems highly improbable.
"Some NASA officials told us that changes to Artemis mission dates should not affect the SLS program’s cost estimate," the report states. "Other officials noted that the program’s cost estimate would be expected to increase to account for the delay to the Artemis IV mission, which shifted from 2026 to 2028." (MORE - details)
