| Abstract: | Two decades of incremental decisions have locked in a vision of human space exploration through an interdependent civil space program centered on the Shuttle and the Space Station. The program lacks the resilience necessary to contain cost overruns, schedule slips, and capability cutbacks. The result is overcommitment, which makes it difficult to sustain the program in a budget-constrained environment. Coping with overcommitment through budget cuts in space science, applications, and technology could split the post-Apollo coalition and jeopardize NASA as an institution. Alternatively, terminating the Space Station could eliminate overcommitment, strengthen NASA's political base, and facilitate restructuring toward a resilient program that is sustainable. A restructured NASA might once again become a model for other agencies. |
