OIG Report on Extending ISS Operations Until 2024

Extending the Operational Life of the International Space Station Until 2024, NASA OIG

"Specifically, the ISS faces a risk of insufficient power generation due in part to faster-than-expected degradation of its solar arrays. Second, although most replacement parts have proven more reliable than expected, sudden failures of key hardware have occurred requiring unplanned space walks for repair or replacement. Third, with the retirement of the Space Shuttle fleet NASA has a limited capacity to transport several large replacement parts to the Station should they be needed. While the ISS Program is actively working to mitigate these risks, anticipating the correct amount of replacement parts and transporting them to the ISS present major challenges to extending Station operations 10 or more years beyond its original expected service life.

The OIG also found the assumptions underlying the Agency's budget projections for the ISS are overly optimistic and that its actual costs may be higher. NASA projects its annual budget for the ISS Program to grow from $3 billion in fiscal year (FY) 2014 to nearly $4 billion by FY 2020. However, ISS Program costs rose 26 percent between FYs 2011 and 2013 and an average of 8 percent annually over the life of the program. Moreover, much of the projected cost increase is attributable to higher transportation costs, and the OIG found unrealistic NASA's current transportation estimates."
