NASA Says SLS Program Costs are ‘Unsustainable’ →

For years, journalists, space nerds and government oversight groups alike have talked about the staggering costs associated with the SLS program, which is the agency’s new moon rocket. As Eric Berger reports, NASA has finally gotten the message:

In a new report, 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 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.

Eric quotes the juiciest parts in his article, but the report’s message is loud and clear: the SLS program cannot continue as it has for the last decade if NASA wants to use this launch vehicle to power future missions to the moon and beyond. Of course, with the agency’s direction and budget set by Congress, fixing this problem isn’t going to be easy.
