米GAO,SLS開発は2017年打上げに対してリソース不足との報告書
What GAO Recommends
Among other actions to reduce risk and allow for continued assessment of SLS progress and affordability, GAO recommends that NASA develop an executable business case for SLS that matches resources to requirements, and provide to the Congress an assessment of the SLS elements that could be competitively procured for future SLS variants before finalizing acquisition plans for those variants. NASA concurred with GAO's recommendations.
