The Augustine Committee studying the future of human spaceflight issued a summary of its report yesterday. (The full report to be issued later.)

Meanwhile, the committee has a web page containing many documents both produced by the committee and those presenting at its public sessions plus many submitted by members of the public. Recently, the paper I submitted in June was posted on the site. Here it is. (PDF)
