The committee was tasked with providing recommendations that "describe a high-level strategic approach to ensuring the sustainable pursuit of national goals enabled by human space exploration, answering enduring questions, and delivering value to the nation" and to consider the evolution of such a program out to 2030 (though our report went on to include considerations out to the 2050s).
The committee outlined a set of pragmatic and aspirational rationales for human spaceflight. The pragmatic rationales being economic benefits, national security, national stature and international relations, inspiration of students and citizens, and scientific discovery. The aspirational rationales were human survival, and shared destiny/aspiration to explore.
Congratulation, and I look forward to reading the report.
From what you've written it sounds wonderfully ambitious. Would dearly love to see humans flying beyond LEO, and a lunar outpost in my lifetime would be extraordinary.
