OIG To NASA: Empty Goals, No Strategy, Not Enough Money

NASA's 2017 Top Management and Performance Challenges, NASA OIG

"... In the long term, NASA's plans beyond EM-2 for achieving a crewed Mars surface mission in the late 2030s or early 2040s remain high level, serving as more of a strategic framework than a detailed operational plan. For example, the Agency's current Journey to Mars framework lacks objectives; does not identify key system requirements other than SLS, Orion, GSDO, and a Deep Space Gateway; and does not suggest target mission dates for crewed orbits of Mars or planet surface landings. If the Agency is to reach its goal of sending humans to Mars in the late 2030s or early 2040s, significant development work on key systems - such as a deep space habitat, in-space transportation, and Mars landing and ascent vehicles - must be accomplished in the 2020s. In addition, NASA will need to begin developing more detailed cost estimates for its Mars exploration program after EM-2 to ensure the commitment from Congress and other stakeholders exists to fund an exploration effort of this magnitude over the next several decades. Finally, NASA's decision whether to continue spending $3-$4 billion annually to maintain the ISS after 2024 - roughly a third of its exploration budget - will affect its funding profile for human exploration efforts in the 2020s, and therefore has significant implications for the Agency's Mars plans.

"... The rising cost of the SLS Program also presents challenges for NASA given the program may exceed its $9.7 billion budget commitment. The Agency plans to spend roughly $2 billion a year on SLS development but has minimal monetary reserves to address any technical challenges that may arise for EM-1 or EM-2. According to guidance developed at Marshall Space Flight Center (Marshall), the standard monetary reserve for a program such as the SLS should be between 10 and 30 percent during development. The SLS Program did not carry any program reserves in fiscal year (FY) 2015 and only $25 million in FY 2016 - approximately 1 percent of its development budget. Moving forward, the SLS Program plans to carry only minimal reserves through 2030, which in our view is unlikely to be sufficient to enable NASA to address issues that may arise during development and testing."

"... Despite the extension, in October 2015, we reported NASA will not have enough time to mitigate several known human space flight risks for future deep space missions. Accordingly, the Agency needs to prioritize its research to address the most important risks in the time available while also ensuring a spacecraft originally designed and tested for a 15-year life span will continue to operate safely and as economically as possible. While the amount of research being conducted on the ISS has increased over the past 8 years, several factors continue to limit full utilization."

"... The selection and balance of NASA's science missions is heavily influenced by stakeholders external to the Agency, including the President, Congress, the science community, and, to a lesser extent, other Federal and international agencies. The President and Congress provide direction through the budgeting and appropriation processes, which has a strong influence on the composition and overall balance of the Agency's science portfolio. The science community - as represented by the National Research Council (NRC) - establishes mission priorities based on a broad consensus within various science research disciplines. These priorities are set forth in the NRC's decadal surveys on the subject matter areas encompassed by the Science Mission Directorate's four divisions ... Managing differing priorities from numerous stakeholders and funding changes on a year-to-year basis (which we described as "funding instability" in a September 2012 report) can lead to inefficiencies, resulting in cost increases and schedule delays that can have a cascading effect on NASA's entire science portfolio."
